Rocket Lab identifies cause of May launch failure; ready to launch again

Capitalism in space: Rocket Lab announced yesterday that it has identified and corrected the cause of a May 15 launch failure and is now ready to resume launches, as early as before the end of July.

Rocket Lab said an investigation by the company traced the root cause to the rocket’s second stage engine igniter system. A problem with the igniter corrupted signals in the computer on the stage, which in turn caused the thrust vector control system to “deviate outside nominal parameters.” The engine computer then shut down the Rutherford engine.

The igniter problem, the company said, resulted from “a previously undetectable failure mode within the ignition system that occurs under a unique set of environmental pressures and conditions” not noticed in previous testing of the engine or on previous Electron launches. Engineers have replicated the problem in the lab and created what Rocket Lab called “redundancies” in the ignition system, including changes to the design of the igniter and how it is manufactured, to prevent the problem from happening again.

Rocket Lab has had two launch failures in the past year, so getting back flying as quickly as possible is critical for them, especially because a lot of new smallsat launch companies are coming up from behind. Virgin Orbit initiated commercial launches this year, having already completed two, and Astra and Firefly both seem ready, based on recent announcements, to make their first orbital launches before the end of this year.

SpaceX completes first static fire test of Superheavy prototype #3

Superheavy booster #3 fires
Superheavy booster #3 fires.

Capitalism in space: SpaceX yesterday successfully completed the first static fire test of the third Superheavy prototype, firing up three Raptor engines for about two seconds.

I have embedded the live stream from NASASpaceflight.com below the fold, cued to just before the engines fire. Because there was a delay of a few minutes from when the static fire was expected and when it actually happened, the announcers had began talking and were caught off guard by the burn.

Next up:

Booster 3 provides a first-time operation for fueling the huge booster with Liquid Oxygen (LOX) and Liquid Methane (CH4) during the test. How much propellant will be loaded, and the schedule for the sequence was unknown. However, NSF’s Adrian Beil wrote a feature on the expectations based on previous experiences with Starship being applied to Super Heavy.

Based on those evaluations, it was expected that Super Heavy would also undergo a Starship-like countdown of 45-60 minutes, with fueling beginning in the 30-40 minute range. Engine chill would then follow at T-12 minutes, ahead of the firing. As with previous Static Fires, the T-10 minute siren sounded, as per the alert notice to local residents. However, as with Starship, mini-holds can be expected, pushing the ignition time to the right. This proved to be the case on Monday.

The booster fired up all three engines for the expected duration, confirmed by Musk before he noted that “depending on progress with Booster 4, we might try a 9 engine firing on Booster 3.”

Booster #4 will be put on the orbital launchpad rather than the test pad, and is likely the booster to be used for the first orbital test flight of Starship, likely to be launched before the end of summer.

Blue Origin completes first commercial suborbital flight

New Shepard just prior to landing
New Shepard just prior to landing.

Capitalism in space: Blue Origin this morning successfully flew its first commercial suborbital flight using its New Shepard spacecraft, taking Jeff Bezos and four other passengers, one paying, to an altitude of 66.5 miles.

The flight lasted just over ten minutes.

I have embedded the video of the flight, cued to just before launch, below the fold. Try to ignore the blather of Blue Origin’s announcer, which fortunately mostly stops once the spacecraft passes 62 miles and enters space. At that point microphones from inside the capsule take over, and you get to hear the reaction of the passengers themselves.

A grand success for Blue Origin and Jeff Bezos. And another grand success for freedom and private enterprise.

Next up, the beginning of regular commercial orbital manned tourist flights, starting in September. Here is the present flight manifest:

  • September 2021: SpaceX’s Dragon capsule flies four private citizens on a three day orbital flight
  • October 2021: The Russians will fly two passengers to ISS to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Watching New Shepard’s first manned commercial flight tomorrow

Blue Origin will be live streaming the suborbital flight tomorrow of its New Shepard spacecraft, carrying Jeff and Mark Bezos, Wally Funk, and passenger 18-year-old Oliver Daemen, his ticket paid for by his father at an undisclosed price.

The broadcast begins at 7 am (Eastern), with launch scheduled for 9 am (Eastern).

The flight itself will be about about ten to twelve minutes total, expecting to reach an altitude exceeding 67 miles, Though it will fly higher than Virgin Galactic’s suborbital flight last week, which reached about 53.5 miles, it will be far shorter. Because Virgin Galactic’s spacecraft takes off attached to the bottom of an airplane, the flight includes more than an hour of flight time getting up to the right altitude to release the spacecraft.

New Shepard launches from the ground, goes straight up, and reaches its maximum height within minutes.

Which is a better deal? That’s up to you. Since orbital tourist flights are now available and will be launching monthly beginning in September, both of these very short suborbital hops seem much less interesting then they would have only two years ago.

Musk donates more big money to revitalizing downtown Brownsville

It appears that a charitable foundation established by Elon Musk has recently decided to up its donations to the Brownsville Community Improvements Corporation by an extra $1 million, the money aimed at helping to revitalized the downtown of Brownsville, the nearest large city to SpaceX’s Boca Chica spaceport.

The donation was revealed during remarks by Josh Mejia, executive director of the Brownsville Community Improvements Corporation, during a Brownsville developers luncheon .

In his remarks, Mejia, pictured above, gave an update on the e-Bridge Center and other quality of life improvements coming to Brownsville. But, he received the biggest applause when he mentioned inward investment by Elon Musk. “I was texting back and forth with my board members and about 45 minutes ago I receive an email from the Musk Foundation. It is like perfect timing. It is like they know we are here. Well, they just mentioned they donated another million (dollars) towards this program. So, now we have $2 million,” Mejia said. The audience cheered.

This donation is all part of the modern game that requires big business enterprises to make payoffs to local and national politicians and “community activists.” Both Elon Musk and Jeff Bezos know this, and are playing the game to hilt. Both know that the politicians and “community activists” have been telling them, “Nice business you got here, shame if something happened to it.” Bezos responded by donating big to DC’s Air & Space museum, while spreading the wealth to many space advocacy groups.

Musk is instead focusing his payoffs to the local community, where it might do the most good for both him and the locals that his business affects. This donation is not the first he has made to Boca Chica, Brownsville, and south Texas. His foundation has also donated $20 million to the county schools, and another $8 million for other downtown Brownsville projects. The results, obviously helped by the business SpaceX is also bringing to the town, have been noticeable.

In the months since Musk pledged his $10 million, at least 10 downtown properties have gone under contract with interested buyers, said real estate broker Bob Torres Jr. Buildings that used to lease for 25 cents a square foot are now leasing for $1 to $1.50 per square foot.

Home prices have increased nationwide due to the pandemic and low inventory. In Brownsville, this trend has been exacerbated by SpaceX. “People are buying houses sight unseen from Washington state, Portland, Oregon,” Torres said. “They’re going above the asking price, which hardly ever happens.” Real estate broker Bruno Zavaleta III had a client drive from Atlanta and buy three houses.

According to the Brownsville/South Padre Island Board of Realtors, the median price for a home in Brownsville was $212,900 in June, up 47 percent from June 2020. To help with inventory, Esperanza Homes is building 675 houses in northern Brownsville. It will develop this master-planned community over the next six to eight years with a nonprofit community housing development organization called “come dream. come build.”

This pumping of donations by Musk to the local community however will not sell well with the mafia in Washington. The money isn’t going to them, and bullies don’t like that, even if the money is really doing good. Bezos understands this. It doesn’t really matter if the money he donates accomplishes anything real. What matters is that he has paid off the thugs who could make big trouble for him in the future.

Right now it is unclear who’s strategy will work best for protecting each company’s interests. Much will hinge on what each company actually accomplishes in the next few years. SpaceX is clearly ahead in this area, but Blue Origin can certainly catch up.

Cracks, chaos, and maybe caves in one place on Mars

Mosaic of Avernus Cavi fissures
Click for higher resolution. Original images found here and here.

Today’s cool image to the right is a mosaic I have made from two images taken by the context camera on Mars Reconnaissance Orbiter (MRO), showing a most intriguing region on Mars dubbed Avernus Cavi, located in the large volcanic plain called Elysium Planitia between the giant volcanoes Elysium Mons and Olympus Mons, a region I like to call Mars’ volcano country.

The mosaic shows in one picture much of the typical terrain in Avernus Cavi. We see many linear depressions or cracks, created when the ground stretched and cracked at weak points. We also see many depressions that suggest sinkholes, places where the surface sagged down because of a void below ground.

The area of knobs and mesas in the picture’s southeast quadrant is very typical Martian chaos terrain, the later result of long term erosion of these cracks and depressions.

The white box shows the area covered by the image below.

The future of SLS?

In this long NASASpaceflight.com article describing the building the second core stage for NASA’s SLS rocket (the stage scheduled to take astronauts around the Moon in September 2023) was also additional information about the status of later core stages, still not entirely funded.

The key tidbit of information is this:

Core Stage-3 is the first build under the new “Stages Production and Evolution Contract” that was initiated in 2019; the contract is not yet completely finalized, with the latest estimate for definitization being early in Fiscal Year 2022 (which begins on October 1st, 2021).

Both NASA and Boeing are proceeding under the assumption that this Congress will approve full funding for later SLS rockets after flights one and two. While the signs strongly suggest that funding for at least two more rockets will arrive, that funding still depends largely on the success of the first unmanned SLS test flight, tentatively scheduled for November-December 2021.

It also depends on the political winds, and when Starship starts reaching orbit somewhat regularly (and cheaply). When that happens, all bets are off on the future of SLS. At some point it will become obvious that it can’t compete against that SpaceX rocket, and Congress will shift its funding appropriately.

Sadly, knowing Congress and the corrupt DC culture, this change will likely only happen after a lot of taxpayer money is wasted on a rocket that is simply too expensive and too cumbersome, and thus not practical for making space exploration possible.

China launches four satellites

Using its Long March 2C rocket, China today successfully launched four satellites, three military reconnaissance satellites and one data communications satellite.

While the first stage crashed inside China (no word on whether it landed near habitable areas), China also claimed it attempted a recovery of the fairings for reuse. At this time no information has been released on what was achieved.

The leaders in the 2021 launch race:

23 China
20 SpaceX
11 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 23 in the national rankings.

The lacy rocks of Mars

Lacy rocks on Mars
Click for full image.

Cool image time! The image to the right, cropped and reduced to post here, was taken on July 16, 2021 by the Mars rover Curiosity, using its high resolution mast camera.

There isn’t much to say. These are alien rocks, created in a place with a gravity only about a third that of Earth’s in a climate that is very different. Their delicate nature suggests we are looking at something that was once more substantial and has since been undergoing erosion.

Nor has it been that unusual to find rocks so dainty on Mars. In fact, the more Curiosity has climbed, the more such things have been visible. And similar things were seen by the rovers Spirit and Opportunity.

How such rocks formed initially in the far past, under what climate conditions, remains the number one mystery on Mars. What is now causing it to flake away into such a finespun gossamer of complexity is as much a mystery, tied more to the climate and geology of Mars today.

This rock sits on the bottom flank of Mt Sharp in Gale Crater, at the highest elevation Curiosity has yet climbed. At this point the rover has just entered a new geological unit, what scientists have dubbed the sulfate unit. The evidence gathered from a distance (that so far appears confirmed by recent observations) suggest that this unit was formed under a fluctuating environment that laid down many layers of sediment as conditions ebbed and flowed.

China test flies reusable suborbital spacecraft

The new colonial movement: China’s state-run press today announced that it had recently flown and landed a new reusable suborbital spacecraft. Here’s their full release:

A reusable suborbital carrier landed stably at an airport in Alxa League in north China’s Inner Mongolia Autonomous Region during a flight demonstration and verification project on Friday.

Earlier on Friday, the carrier was launched from the Jiuquan Satellite Launch Center in northwest China’s Gobi Desert. Its first flight mission was a complete success.

Developed by the China Aerospace Science and Technology Corporation, the reusable suborbital carrier can be used in the space transport system.

The success of the flight has laid a solid foundation for the development of China’s reusable space transportation. Enditem

The release provided no further information. It also provided no images.

This could very much be a real thing, but it also could be entirely fake. The timing of such a factual-devoid press release, coming as it does between two different American commercial suborbital flights, suggests the Chinese government does not want to appear left out, and is claiming, without producing any evidence, that it too has a reusable suborbital spacecraft.

If this release is fake, it also does not mean that China does not have such a spacecraft in development. In fact, it almost certainly does. Like the Soviet Union, China’s state-controlled press has a tendency to exaggerate their achievements for propaganda reasons. But like the Soviet Union, China is careful to base the exaggerations on actual achievements or plans, no matter how tentative.

Based on this, I suspect that what this release tells us is that China’s government is building such a thing, but might not have actually flown it yet. If they have as the press release claims, then expect some images in the next week or so.

Hubble returned to science operations

Engineers today completed their testing of their computer hardware fix on the Hubble Space Telescope and took it out of safe mode, allowing science observations to resume after more than a month.

The first observation is scheduled for Saturday afternoon after some instrument calibrations are completed. Most observations missed while science operations were suspended will be rescheduled for a later date.

Now let us all pray that there are no more major failures for the next few years until the U.S. capabilities in space grow and a relatively fast mission to repair the telescope is possible.

First attempts to map the layered geology of Mars

layers in Jiji Crater on Mars
Click for full image.

Today’s cool image illustrates well the central task of much of today’s geological research on Mars, using the orbital images to try to map out the visible geological layers seen, and figure out if those layers mark over wide regions specific geological epochs, as they do on Earth.

The photo to the right, cropped and reduced to post here, was taken on May 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and featured on July 12th as a captioned image entitled “Layers Blanket a Crater Floor.” From the caption:

This image shows a layered rock formation within Jiji Crater that has eroded into buttes and stair-like layers.

This formation extends west and east. Similar layered rocks are within several craters in Arabia Terra and Meridiani Planum, including [nearby] Sera and Banes craters. The similarities suggest that the same process was forming deposits over a large geographic area long ago. Our image also indicates that much of the formation has eroded away relative to what has remained.

As you can see in the photo, the layers form a neat staircase of terraces descending from the south crater rim to the crater floor. They suggest that once the crater was filled with this material, which over time eroded away.

An image of similar layered buttes and mesas in Sera crater, only about 20 miles away, was featured here on Behind the Black in December 2020 The overview map below shows the relationship between Jiji, Sera, and Banes craters.

Juno team creates dramatic animation of Ganymede/Jupiter fly-by

Using images from Juno’s fly-by of both Ganymede and Jupiter on June 7th and 8th, the science team has produced a dramatic animation, with background music, showing that fly-by from the point of view of the spacecraft.

I have embedded it below the fold.

The 3:30-minute-long animation begins with Juno approaching Ganymede, passing within 645 miles (1,038 kilometers) of the surface at a relative velocity of 41,600 mph (67,000 kph). The imagery shows several of the moon’s dark and light regions (darker regions are believed to result from ice sublimating into the surrounding vacuum, leaving behind darkened residue) as well as the crater Tros, which is among the largest and brightest crater scars on Ganymede.

It takes just 14 hours, 50 minutes for Juno to travel the 735,000 miles (1.18 million kilometers) between Ganymede and Jupiter, and the viewer is transported to within just 2,100 miles (3,400 kilometers) above Jupiter’s spectacular cloud tops. By that point, Jupiter’s powerful gravity has accelerated the spacecraft to almost 130,000 mph (210,000 kph) relative to the planet.

Among the Jovian atmospheric features that can be seen are the circumpolar cyclones at the north pole and five of the gas giant’s “string of pearls” – eight massive storms rotating counterclockwise in the southern hemisphere that appear as white ovals. Using information that Juno has learned from studying Jupiter’s atmosphere, the animation team simulated lightning one might see as we pass over Jupiter’s giant thunderstorms.

The lightning shown on Jupiter, while entertaining, is a complete fantasy. The flashes are much too bright and large. At the scale created, some would cover the Earth. In reality, that lightning wouldn’t be visible until you are very very close, and even then probably difficult to spot in the vastness of Jupiter.

Maezawa reveals status of competition to join him on a private Starship mission to Moon

Capitalism in space: In a video released yesterday Japanese billionaire Yusaku Maezawa provided an update on his Dear Moon competition for choosing the eight individuals who will join him on his private Starship mission around the Moon.

The mission has changed a lot since it was first announced in 2018. Maezawa had planned to invite artists onboard the Starship and venture with them on a circuit around Earth’s only natural satellite. But earlier this year, he changed the process and opened up spots to practically everyone, calling on budding lunar explorers to register for a ticket aboard the Starship and then produce videos on why they want to go to space.

I have embedded the video below. In it Maezawa reveals that he received more than a million applications from every single country on Earth, with many sending short videos describing why they should be chosen. The video provides a sampling of clips from those videos.

What struck me most while watching the video is how completely confident all the applicants were that this private mission on Starship will fly. Even though this is a manned mission around the Moon, something that has only been done nine times, and not for a half century, all seemed entirely sure Maezawa’s mission would happen, and wanted to be on it. I was also struck by the variety of applicants from many places.

Capitalism and freedom is opening the heavens for all humans. And it is about time.

NASA pushing for an SLS launch before the end of the year

According to a statement by NASA administrator Bill Nelson earlier this week, the agency is working hard in its stacking of the SLS rocket in Florida, with the goal of launching before the end of the year.

That statement was revealed in the last sentence of this article describing the work on getting SLS ready, work that appears to be moving along briskly with few surprises.

The present official targeted launch date is set for November. The agency had said it would take between six to ten months to get the rocket ready after the core stage arrived at Kennedy in May. This pointed to a launch sometime between November and March. Right now it appears that NASA is trying very hard to meet that earlier date.

This aggressive effort to launch on schedule is behavior quite out of character for the NASA of the past three decades. In the past, the agency would have moved leisurely along, so that those four months of margin would have almost certainly been used and the launch would have been delayed until March.

I suspect this push now to launch on time is partly generated by a fear that SpaceX’s Starship will reach orbit before SLS. If that happens it will be a major embarrassment to NASA, considering that the agency has spent about three times longer and ten times more money on its rocket than SpaceX.

Isn’t competition wonderful? It even makes government work more efficiently.

Stay tuned. There is still a lot of time between now and November. This race between comparable rockets being built by the government and a private company appears to be neck and neck as we head down the stretch.

Thales Alenia to build first two modules of Axiom’s commercial space station

Capitalism in space: The Italian company Thales Alenia today announced it has finalized the contract to build the first two modules of Axiom’s private commercial space station, set to be docked to ISS initially but eventually to fly independent once ISS is decommissioned.

Total price for the contract is 110 million euros. According to the press release, they are targeting 2024 and 2025 for launching these modules, which will be able to house as many as eight residents.

Based on its past successful experience in building modules for the International Space Station, Thales Alenia Space is responsible for the design, development, assembly and test of the primary structure and the Micrometeoroid & Debris Protection System for the two Axiom modules.

The welding activities of the primary structure of the first module will start in September 2021, with the assembly process concluding in 2022. The first module will arrive at Axiom facilities in Houston in July 2023, where Axiom will integrate and outfit the core systems and certify it for flight prior to shipping to the launch facility.

With the launch of this station, human spaceflight in the United States will become completely independent of the federal government. Private companies will own the rockets, spacecraft, and stations, and the government will no longer have a major say on what goes on in space. The NASA bureaucracy that makes getting an experiment onto ISS cumbersome, difficult, and discouraging will be out of a job. (An example: In the 2000s American scientists studying plant growth in weightlessness ended up launching their experiments with the Russians because getting NASA approval turned out to be too difficult.)

This doesn’t mean that it will be easy to get a payload or experiment onto Axiom’s station. The demand will be quite high. It just means that the decision will no longer reside with the government, but with the private companies and citizens of the United States.

As it always should have been.

Furthermore, that the demand is going to exceed the supply will mean that additional stations will be built, and quickly, because the lure of profit will be there. For example, many of the commercial medical experiments that were on the verge of paying off but were shut down after the Challenger accident in 1986 could very well be brought back to life.

Engineers report Hubble fix appears successfully

Engineers this morning announced that their attempt to switch to backup computer hardware on the Hubble Space Telescope was successful.

The switch included bringing online the backup Power Control Unit (PCU) and the backup Command Unit/Science Data Formatter (CU/SDF) on the other side of the Science Instrument and Command & Data Handling (SI C&DH) unit. The PCU distributes power to the SI C&DH components, and the CU/SDF sends and formats commands and data. In addition, other pieces of hardware onboard Hubble were switched to their alternate interfaces to connect to this backup side of the SI C&DH. Once these steps were completed, the backup payload computer on this same unit was turned on and loaded with flight software and brought up to normal operations mode.

They are now doing tests to make sure everything is working as expected, and preparing the telescope to bring it out of safe mode and resume science operations.

This is great news, but to bring everyone down to Earth, we must remember that Hubble no longer has any redundancy in this area. Should there be another similar computer failure, the telescope will then be dead in the water, with the only way to bring it back a manned or robotic mission — something we presently do not have the capacity to do — to replace these units.

Winner of Blue Origin auction for suborbital flight will not fly on July 20th

Capitalism in space: Blue Origin today announced that the $28 million winner of the auction to buy a seat on the first commercial flight of its suborbital spacecraft New Shepard on July 20th will not be on board, and will instead be replaced by an 18-year-old.

Blue Origin announced Thursday that instead of a $28 million auction winner launching with founder Jeff Bezos on Tuesday, Dutch runner-up Oliver Daemen will be on board. The company said he’ll be the first paying customer, but did not disclose the price of his ticket. …According to Blue Origin, Daemen took a year off after graduating from high school last year to obtain his private pilot’s license. He’ll attend the University of Utrecht in the Netherlands in September. His father is Joes Daemen, founder and CEO of Somerset Capital Partners, a private equity firm in Oisterwijk, Netherlands. Both father and son are already in the U.S. preparing for the launch, according to a company representative.

…Blue Origin said the yet-to-be-identified winner of the charity auction is stepping aside because of a scheduling conflict and will catch a future flight. Daemen was going to be on the second launch for paying customers.

The company has yet to open ticket sales or disclose its prices to the public. That’s expected following Bezos’ flight.

There are some puzzles here. Did Daemen bid during the auction? Was his bid second? If not, why has he been pushed to the head of the line, even before Blue Origin has opened ticket sales or announced its prices?

Moreover, much of this does seem to be hype and pr, rather than real achievement. More important would be an announcement saying that the BE-4 engine is finally ready, making possible orbital flights on New Glenn and ULA’s Vulcan rocket.

Nonetheless, it is nice that Bezos is taking this teenager into space, as is his decision to also give a seat to 82-year-old Wally Funk, one of the women who applied to fly during the Mercury program in the 1960s but was rejected.

Thailand’s government approves new space law

The new colonial movement: The cabinet of Thailand has approved a new space law that will establish a space agency and establish a regulatory framework for both its private and public space industry.

The core principles included the planning of a policy to support both state and public sector participation in a “new space economy”, the creation of a national space policy committee to draw up space policy. The bill also sets up a national space administration agency to perform secretarial tasks for the national space policy committee, with a director that will have the power to appoint officials.

As the language of the bill is not available, it is unclear exactly what the bill does, other than establish a government framework for Thailand’s space industry. Its passage however illustrates the growing international passion for joining the new commercial effort in space. Thailand apparently does not wish to be left behind.

India successfully completes static fire testing of rocket engine for human flights

The new colonial movement: India has successfully completed the third long duration static fire tests of its Vikas rocket engine, to be used on its planned manned space mission dubbed Gaganyaan.

[T]he Vikas engine is the workhorse liquid rocket engine powering the second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and the four strap-on stages of the Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.

Experts point out that the successful testing is necessary as the testing is part of the human rating of a rocket that was not originally designed to launch humans into space. Every space agency follows its own standards of human rating of a launch vehicle and there are no global standards. “This test is one of the critical items which need to be checked in human rating GSLV Mk-III. Semi-Cryogenic engine SE-200 which will replace Vikas is still under development and its developmental times will not match the ambitious Gaganyaan timelines. Vikas is one of the most reliable engines in the world and has proved its mettle.

If you look at PSLV, GSLV Mk-II and GSLV Mk-III missions where Vikas has been used, the burn profile or duration is approximately around 150-160s only on a typical flight. Testing its performance above its designed operational limit is essential to ensure engine reliability against any event of a mishap.

In other words, for the manned mission Vikas will have to burn for a much longer time than its normal profile. They have now successfully shown that it can handle that long burn time.

Bezos donates $200 million to Air & Space Museum

Jeff Bezos, founder of Amazon and Blue Origin and about to fly on the first commercial suborbital flight of his New Shepard spacecraft, today announced the donation of $200 million to the Air and Space Museum in Washington, DC.

The Smithsonian said $70 million of the money would support museum renovations. The other $130 million would go toward building a new education center at the museum called the Bezos Learning Center to inspire students to promote innovation and explore careers in science, math and engineering.

While this is a very gracious and generous act, in the long run it might actually have been better for Bezos to have used this money to get his rocket company off the ground. Success in that manner would be far more effective in inspiring students. Once Blue Origin is actually launching humans into orbit to explore the heavens such a donation might have made better sense. Those student would not only be inspired by the achievement, Bezos would then be providing them a way to join in.

Still, the gift will do much to help maintain the nation’s capabilities in space. Good for Bezos.

FAA threatens shutdown of SpaceX’s Starship program at Boca Chica

Banned by the FAA?
Starship banned by the FAA?

They’re coming for you next: An FAA official revealed yesterday that the agency has not approved the launch tower that SpaceX is building for its Starship/Superheavy rocket in Boca Chica, Texas, and threatened that if disapproved the government would force the company to tear it down.

The Federal Aviation Administration warned Elon Musk’s SpaceX in a letter two months ago that the company’s work on a launch tower for future Starship rocket launches is yet unapproved, and will be included in the agency’s ongoing environmental review of the facility in Boca Chica, Texas. “The company is building the tower at its own risk,” an FAA spokesperson told CNBC on Wednesday, noting that the environmental review could recommend taking down the launch tower.

The FAA last year began an environmental review of SpaceX’s Starship development facility, as Musk’s company said it planned to apply for licenses to launch the next-generation rocket prototypes from Boca Chica. While the FAA completed an environmental assessment of the area in 2014, that review was specific to SpaceX’s much-smaller Falcon series of rockets.

This revelation from FAA officials is most interestingly timed, coming on the same day as this garbage article about the terrible environmental damages some activists imagine SpaceX’s launch facility might someday cause. As is usual for a mainstream news source, the article makes no reference to the wildlife preserve that surrounds the Kennedy Space Center in Florida, where we have empirical proof for more than a half century that a spaceport does no harm to the environment and actually acts to protect it from development.

Nor was this the only such attack article in the past two days. Here is just a sampling:

Blue Origin distributes $19 million of the $28 million earned for its July 20th suborbital flight

Blue Origin today announced the nineteen non-profits that will receive $1 million each, taken from the $28 million that a single as-yet unnamed person is paying to fly with Jeff Bezos on the first commercial suborbital manned flight of New Shepard on July 20, 2021.

All of the organizations are advocates for space exploration. A majority foster education for the young. Two are pro-women, pushing gender politics in space.

The remaining $9 million will be used by Blue Origin’s non-profit to encourage space-focused curriculum and its project to encourage people to send postcards into suborbital space on its New Shepard spacecraft.

All in all the list of recipients surprised me. I had expected this money to go to many of the very leftist environmental groups that Jeff Bezos loves. Instead, the list is entirely space-focused, though it does tend to favor organizations that mostly aim to maintain the status quo of a big government space program or push for gender or racial politics. That there is a large variety of organizations that push many different approaches to encouraging space exploration however is refreshing.

Nonetheless, except for a few that actually educate children, most are advocacy groups. Compare that to the charity being produced by SpaceX’s first manned commercial flight in September, dubbed Inspiration4. That flight is pumping big bucks directly into St. Jude’s Research Hospital to help it cure children from cancer.

Hubble update: Engineers pinpoint issue, prepare to fix it

In an update today on the status for bringing the Hubble Space Telescope back into science operations, the engineers say they think they have pinpointed the failed unit, and are ready to do the switch to a backup.

A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were not successful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Power Control Unit (PCU).

The PCU also resides on the SI C&DH unit. It ensures a steady voltage supply to the payload computer’s hardware. The PCU contains a power regulator that provides a constant five volts of electricity to the payload computer and its memory. A secondary protection circuit senses the voltage levels leaving the power regulator. If the voltage falls below or exceeds allowable levels, this secondary circuit tells the payload computer that it should cease operations. The team’s analysis suggests that either the voltage level from the regulator is outside of acceptable levels (thereby tripping the secondary protection circuit), or the secondary protection circuit has degraded over time and is stuck in this inhibit state.

Because no ground commands were able to reset the PCU, the Hubble team will be switching over to the backup side of the SI C&DH unit that contains the backup PCU. All testing of procedures for the switch and associated reviews have been completed, and NASA management has given approval to proceed. The switch will begin Thursday, July 15, and, if successful, it will take several days to completely return the observatory to normal science operations.

Engineers did a similar switch in 2008, so they are very confident it will work this time also. However, once done, the telescope will no longer have backups for any of these computer modules. The next failure in any of them will shut the telescope down, for good.

Craters on Ganymede’s striped surface

Craters on Ganymede

Cool image time! The photo to the right, cropped to post here, is a color enhanced section taken from of one of the images taken by Juno when it did a close fly-by of the Jupiter moon Ganymede back on June 7, 2021.

The enhancement was done by citizen scientist Navaneeth Krishnan, using a wider Juno image of Ganymeded enhanced by citizen scientist Kevin Gill. That wider image is below, and marks the area covered by this first image with a white box.

In this one picture we can see many of the geological mysteries that have puzzled scientists since the Galileo orbiter first took close-up images back in the 1990s. We can see patches of grooved terrain with the grooves in the different patches often oriented differently. We can also see bright and dark patches that while they overlay the grooved terrain they bear no correspondence to those grooved patches. And on top of it all are these small craters, impacts that obviously occurred after the formation of the grooves.

NASA awards three contracts to develop nuclear propulsion concepts

Capitalism in space: NASA yesterday awarded three different contracts to three different corporation partnerships to develop new nuclear propulsion concepts for use in space.

The contracts, to be awarded through the DOE’s Idaho National Laboratory (INL), are each valued at approximately $5 million. They fund the development of various design strategies for the specified performance requirements that could aid in deep space exploration.

Nuclear propulsion provides greater propellant efficiency as compared with chemical rockets. It’s a potential technology for crew and cargo missions to Mars and science missions to the outer solar system, enabling faster and more robust missions in many cases.

The contracts went to these partnerships:

  • Lockheed Martin and BWX Technologies
  • Aerojet Rocketdyne, General Atomics Electromagnetic Systems, and X-energy
  • Blue Origin, Ultra Safe Nuclear Technologies, Ultra Safe Nuclear Corporation, General Electric Hitachi Nuclear Energy, General Electric Research, Framatome, and Materion

Once the concepts are put forth at the end of the 12-month contracts, the DOE’s laboratory will review them and make recommendations to NASA for further work.

This contract, along with other NASA contracts to develop nuclear power for use on planetary surfaces, strongly suggests that the fear of using nuclear power in space is receding. If so, the capabilities in space will increase significantly in the coming years.

Facebook gets out of satellite business; “sells” its employees to Amazon

Capitalism in space: Facebook has now apparently abandoned a project to launch its own communications satellites and instead has made a deal with Amazon whereby it sold its satellite division to the Bezos-founded company, where they joined Amazon’s Kuiper communications satellite project.

Over the past year, Amazon has revealed details about Project Kuiper’s antenna design, selected United Launch Alliance’s Atlas V rocket for the initial satellite launches, and acquired still more office space for Kuiper employees in Redmond.

According to The Information, the employees who came to Kuiper from Facebook in April are based in the Los Angeles area. They are said to include physicists as well as optical, prototyping, mechanical and software engineers who have worked on aeronautical systems and wireless networks. One of the employees, Jin Bains, was formerly Facebook’s head of Southern California connectivity and is now described on his LinkedIn page as a director on the Project Kuiper team.

The Information reported that Amazon paid Facebook as part of the deal for the employee switchover, but did not provide further details. “It’s not unheard of for big companies to buy groups of employees from one another, just as they often buy small startups to beef up staff in various parts of their business,” The Information’s Sarah Krouse and Sylvia Varnham O’Regan explained. [emphasis mine]

This deal reveals a number of immediate facts, as well as one long term troubling one. First, it indicates as mentioned Facebook’s abandonment of its space ambitions.

Second, it suggests that Amazon might finally be recognizing that the people running its Kuiper satellite project are taking far too long to get it off the ground. Though proposed approximately the same time as SpaceX’s Starlink constellation, Kuiper remains unlaunched with no launches even scheduled, while SpaceX has more than 1,500 satellites in orbit, has been providing test service to customers in selected areas, and is about to become operational globally. This difference is achievement might be explained by this fact: The person Amazon hired to run its Kuiper project was someone Elon Musk fired in 2018 from his Starlink project because that person was taking too long to get it built and launched.

The new hires suggest that Amazon might have finally recognized this issue.

Finally, the long term troubling fact.

Clashing layers in Mars’ largest canyon

Clashing layers on a mountain slope on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on May 27, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows the clash of different layers on the western slope of a mountain within Mars’ largest canyon, Valles Marineris.

The scientist have labeled this a “possible angular unconformity.” In geology an unconformity generally refers to a gap in a series of layers, a period when instead of the layers being deposited they are being eroded away, leaving no record for that time period. An angular unconformity adds tilting to the older layers, which after erosion are then covered by new layers that are oriented somewhat differently.

Based on these definitions, what the scientists suspect is that the brighter layers to the left and lower down the mountain are older. After a period of erosion new layers were deposited on top at a different angle, forming the stripe of layers going from center left up to center right.

The swirly nature of the material on the top of the ridge suggests to me that these layers might be volcanic in nature, but that’s a pure uneducated guess. What some scientists do believe (but have not yet conclusively proven) is that the lower older layers are sediments laid down by an ancient lake that once filled the canyon here.

The overview map below provides a wider view and some context.

SpaceX unveils third drone ship for landing Falcon 9 boosters

Capitalism in space: SpaceX’s founder Elon Musk yesterday unveiled the completion of its third drone ship for landing Falcon 9 boosters in the ocean and returning them to port.

The new ship will be put in place in Florida to support Atlantic launches of Falcon Heavy and the flagship rocket of SpaceX, the Falcon 9, that regularly sends Starlink broadband satellites to orbit and NASA astronauts and cargo to the International Space Station, among other customer requests.

This will give the company two drone ships in Florida and one in California, allowing them to do launches at an even faster pace than the one launch every 2 weeks or so since the beginning of the year. The ship also is designed to be more efficient than the older ships, no longer requiring a tug to take it out into the Atlantic.
