One of Jupiter’s mid-sized storms

One of Jupiter's mid-sized storms

Cool image time! The Juno image on the right, cropped to show here, focuses in on one of Jupiter’s mid-sized storms near its high northern latitudes and just on the edge of the chaotic polar region.

This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1); it has been tracked at least since 1993, and may be older still. An anticyclone is a weather phenomenon where winds around the storm flow in the direction opposite to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6,000 kilometers) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Be sure to take a look at the full image, which provides a bit of context.

International group forms to get UN protection of Apollo sites

8:43 am

An international group of lawyers, academics, and business people has formed an organization called “For All Moonkind,” aimed specifically at getting UN protections for the six lunar Apollo sites.

They are going to the UN because, based on the Outer Space Treaty, this is the only place that has jurisdiction. Unfortunately. This quote illustrates why:

“Though we are based in the US, we are an international organization,” said Michelle Hanlon, US space lawyer and Co-Founder of For All Moonkind. “Humaid Alshamsi [the UAE participant] brings tremendous experience in public and private aviation and space law to our team. We are thrilled that he has agreed to join our effort.”

For All Moonkind was critical of the auction by Sotheby’s of the Apollo 11 Contingency Lunar Sample Return Bag used by astronaut Neil Armstrong. “The astronauts of the Apollo project represented all of us here on Earth,” explained aviation and space lawyer and Advisory Council Member Humaid Alshamsi, “they went to the Moon in peace for all, and the relics of their historic achievement should be shared by all. The loss of this artifact to a private collector is a loss for humanity.”

The Outer Space Treaty forbids any nation from claiming territory in space, thus leaving it under the control of the UN and the international community, a community that — as demonstrated by this quote — is hostile to capitalism and private enterprise. While I laud this group’s desire to protect these historic sites, I fear their actions are going to place limits on the freedoms and property rights of future space colonists.

New images downloaded from Curiosity for the first time in two weeks

9:15 am

For the first time since communications with Mars ceased two weeks ago because the orbits of the Earth and Mars had placed the Sun in between, new images have been downloaded from Curiosity.

For the past two weeks, the last raw images posted had been from sol 1760. Today, the Hazard Avoidance Cameras (Hazcams) added daily images through sol 1774 (taken as per previously uploaded commands). The images all show the same view, the part of Vera Rubin ridge that the rover has been circling around to get to the place where it will be easier to climb up. The science team probably programmed this sequence so that they could look for any changes from wind, over time.

No new images from either Curiosity’s other cameras or from Opportunity have yet appeared, but I expect this to soon change.

India to almost double launch rate with new rocket assembly building

9:01 am

Capitalism in space: India’s space agency ISRO is building a second rocket assembly facility at its Sriharikota spaceport so that it can prepare two rockets for launch simultaneously.

“We have not reached the limit of two launchpads. With the new assembly facility, we will be able to assemble more vehicles. Once we are able to assemble more rockets but not able to launch them even by reducing launch timings, then we will start work on the third launchpad. But for that, we first need (government’s) approval. So, we are gradually working to eliminate all bottlenecks to increase the frequency of launches.” With the new facility, Isro can achieve launch 12 rockets in a year from the seven at present.

The Times of India also recognizes the value of this upgrade. To quote the article, “With the increased frequency of foreign satellite launches, ISRO can rake in big moolah.”

I couldn’t have said it better myself.

Vector live streaming test launch

8:53 am

Capialism in space: If you want to watch today’s test launch by Vector, the company is live streaming the event.

As I post, the rocket is vertical in a small clearing surrounded by woods, with a small group of workers at its base.

Update: One minute to launch.

Update: Launch at 9:25 am. The rocket cleared the tower perfectly. We will have to wait for updates from the company to see how things went beyond that.

Lockheed Martin begins construction of new satellite factory

7:12 pm

Capitalism in space: Lockheed Martin has begun construction of a $350 million satellite factory in Colorado, with expected completion in 2020.

At the moment, Lockheed does not have a competitive rocket. Moreover, its only big space project is Orion, which might never fly more than twice, if that. Thus, this shift to satellites makes some sense, as it will be difficult now for the company to gain market share in the launch and manned spacecraft markets. It is too far behind. However, there is a new industry developing in smallsats, and Lockheed is well positioned to get in at the start.

Update: I do this all the time, but I made a mistake here and assigned the Delta family of rockets to Lockheed Martin. For some reason I make this mistake often, switching Atlas 5 and Delta and Lockheed Martin and Boeing. I apologize for the error.

An explorer’s club for Mars missions

9:24 am

An international group based in New Zealand has put together a new organization, dubbed the Martian Trust, modeled after National Geographic as a way to privately fund space missions.

The Martian Trust is similar to the early National Geographic Society, a non-profit which funded exploration of the world’s furthest reaches through everyday members, magazine subscribers, and wealthy philanthropists. The intent is to tap into the global space-lovers, who will help fund projects in exchange for martian stories, products and experiences produced.

They are using crowd-funding to obtain funds. Trustees will be picked either by a vote from those who contributed small amounts, or because they themselves contributed more than $5 million.

Virgin Orbit’s launch jumbo jet arrives at company’s base in California

9:19 am

Capitalism in space: The modified jumbo jet that Virgin Orbit is going to use as the first stage of its LauncherOne rocket, being designed to put smallsats into orbit, arrived yesterday in Long Beach to put it close to the company’s base of operations.

While some of this story is the typical hype we all should expect — and question — from a company run by Richard Branson, Virgin Orbit looks more like the real thing. Last year it was separated from Virgin Galactic, the company that has been promising and failing to fly tourists on suborbital flights now for more than a decade. I suspect this happened because the LauncherOne group did not want to be saddled any longer with the failures of the SpaceShipTwo group.

I have been predicting that LauncherOne will reach space before SpaceShipTwo, and this story only adds weight to that prediction. They have real satellite contracts, and expect their first launch to occur in 2018. While that schedule might not hold, I suspect it will not be far wrong.

Booking service now available to rocket and satellite companies

9:41 am

Capitalism in space: A new company, Precious Payload, is now offering a booking service to both rocket companies and satellite manufacturers to make it easier to match them together.

In the Precious Payload concept, launch providers and brokers share and exchange their immediate and future availability of inventory with the independent Precious Payload GDS, including the status of reservations of inventory (eg. available, reserved, booked, etc.).

Anyone who wants to launch a satellite uploads their mission profile into the Precious Payload GDS. A special algorithm then analyses the data and shows the real-time availability of launchers for specific types of mission.

Launch providers, both manufacturers and brokers, can benefit from the Precious Payload GDS by being able to open another sales channel for their core businesses. They not only receive and process the booking requests from satellite companies, but also browse through the backlog of satellites waiting for launch and bid for their business. Advanced services like rebooking the launches and effectively managing client cancellations and launch failures raise the bar for customer experience in the market.

To pitch their product, they are presently offering their initial service for free.

Next test flight of Rocket Lab’s Electron rocket delayed

9:34 am

Capitalism in space: Rocket Lab has revealed that the second test flight of its rocket Electron is still several months away.

Rocket Lab is in the early stages of a three-vehicle test programme and Moon Express is still developing its lander at its facilities at Cape Canaveral, from where Apollo missions were launched. Rocket Lab’s first test launch successfully made it to space in late May. The first stage performed as it should but the second stage failed to deliver the payload to orbit.

Results of data analysis from the test flight could be available some time next week.

Earlier this month Rocket Lab founder Peter Beck said the company and its investors had confidence in the programme and they had another five rockets in various stages of production.
Beck said then a second test launch was about two or three months away and the company hoped to get its commercial launches underway as soon as it was satisfied with the test programme.

The company had previously said it hoped to launch the second test flight in mid-2017. It appears now that the second launch will not happen before October.

The article is strangely focused on selling the idea that Moon Express’s Google Lunar X-Prize flight, which must occur by the end of this year, is still on track. I don’t see how, with this news. Rocket Lab must first complete its three test flights, and I don’t see how they can do this, get their results, and update their engineering and still get this first commercial flight off by December.

Solid gold Apollo 11 lunar module replica stolen from Armstrong museum in Ohio

9:23 am

On Friday thieves broke into the Neil Armstrong Museum in Ohio and stole a solid gold miniature replica of the Apollo ll lunar module that had been one of three gifted to the three astronauts in Paris during their post-flight world tour.

Police responded to a burglary alarm at the Armstrong Air and Space Museum in Wapakoneta, Ohio, shortly before midnight on Friday (July 28), where the 18 karat gold, five-inch-high (13 centimeter) miniature lunar lander was found missing. “Entry to the museum was discovered and taken was a solid gold replica of the 1969 Lunar Excursion Module that landed on the moon,” Russel Hunlock, Wapakoneta police chief, stated in a release. “The piece is very rare as it was presented to Neil Armstrong in Paris, France shortly after the moon landing.”

I am not hopeful the replica will be recovered. It was obviously stolen for its gold, and I would expect the thieves to quickly break it apart and melt the gold down for sale.

Japanese private rocket launch terminates early due of communication failure

9:14 am

Capitalism in space: The first launch of the first privately-built and funded Japanese suborbital rocket was terminated early today because of a communications failure.

The rocket’s developers, Interstellar Technologies, said they aborted the launch after about 80 seconds and it landed about 8 kilometers (5 miles) offshore. The aim had been to launch the rocket, called “Momo,” to an altitude of 100 kilometers (62 miles), but it only traveled about 30-40 kilometers (19-25 miles).

The Great Red Spot

9:43 am

The Great Red Spot

Cool image time! The image on the right, reduced in resolution to post here, shows one of the close-ups taken by Juno during its recent close fly-by of the Great Red Spot. What makes it different is its colors.

This image of Jupiter’s iconic Great Red Spot was created by citizen scientist Björn Jónsson using data from the JunoCam imager on NASA’s Juno spacecraft.

This true-color image offers a natural color rendition of what the Great Red Spot and surrounding areas would look like to human eyes from Juno’s position. The tumultuous atmospheric zones in and around the Great Red Spot are clearly visible.

Normally scientists enhance the colors to bring out the details. This version does not, which definitely makes it a little less dramatic but more accurate. Even so, the whirls and storms within the Spot are clearly visible.

The image was taken on July 10 from about 8,600 miles away. Note also that the entire Earth would fit inside the storm.

SpaceX now one of the world’s most valuable companies

9:37 pm

Data from a new round of investment capital fundraising says that SpaceX is now valued at $21 billion, placing it among the only six venture-backed companies worth more than $20 billion.

The article also notes that this new valuation is up from the $12 billion listed only two years ago.

Update: As noted by my readers, I have revised the post to note that this story refers not to all companies but to those that obtained their financing privately.

Video of Iranian launch today

9:22 pm

The Iranians have released video of today’s rocket launch.

I’d love a translation of what the crowd is chanting. I would also encourage the engineers in my readership to look at this and tell me if the launch looks right, and if there is any way to judge whether it is an rocket for orbital satellites or a missile. We still have no evidence the rocket successfully put anything in orbit.

Meanwhile, the Trump administration has called this launch a breach of a UN resolution forbidding Iran from developing ballistic missiles.

Cameras on next Kepler-like exoplanet space telescope out of focus

9:34 am

NASA has revealed that the cameras on the Transiting Exoplanet Survey Satellite (TESS) become slightly out of focus when they are cooled to -75 Celsius, the temperature they will experience in space.

NASA has also decided that the fuzziness is not enough to require a fix, and is proceeding with the mission as is, despite concerns expressed by scientists.

Alan Boss, an astronomer with the Carnegie Institution, brought up the issue in a summary of a meeting last week of the Astrophysics Advisory Committee, of which he is a member. “That could have some big effects on the photometry,” he said of the focus problem. “This is certainly a concern for the folks who know a lot about photometry.”

TESS will use those cameras to monitor the brightness of the nearest and brightest stars in the sky, an approach similar to that used by Kepler, a spacecraft developed originally to monitor one specific region of the sky. Both spacecraft are designed to look for minute, periodic dips in brightness of those stars as planets pass in front of, or transit, them. Chou said that since TESS is designed to conduct photometry, measuring the brightness of the stars in its field of view, “resolution is less important compared to imaging missions like Hubble.” However, astronomers are concerned that there will be some loss of sensitivity because light from the stars will be spread out onto a slightly larger area of the detector.

“The question is how much science degradation will there be in the results,” Boss said. “The TESS team thinks there will be a 10 percent cut in terms of the number of planets that they expect to be able to detect.”

It could be that NASA has decided that the cost and delay required to fix this is not worth that 10% loss of data.

Time/PBS video documentary nominated for Emmy despite factual error in title

9:25 am

Fake news: The Time/PBS video documentary A Year in Space has been nominated for an Emmy award, despite a blatant factual error in the show’s title.

I haven’t seen the documentary, and so it might a great achievement. Nonetheless, this mission only lasted 340 days, not a year, and to call it “a year in space” is not only false, but an outright lie. For a news organization to start out this wrong, in the title, and then for it to get an Emmy nomination, tells us a great deal about the standards of accuracy in television news.

Breakthrough Starshot puts smallest satellites ever into orbit

9:18 am

Breakthrough Starshot, the privately funded $100 million effort to launch a probe to the nearest star, has put into orbit the world’s smallest satellites ever.

The six prototypes, dubbed Sprites, weigh only 4 grams and contain solar panels, computers, sensors, and radios on a surface equal to that of a U.S. postage stamp. Developed by researchers at Cornell University and transported into space as secondary payloads on a rocket built by the Europe-based company OHB System AG, the nanosatellites are being tested for electronics and communication performance in orbit.

The significance here is not so much that this advances the project’s interstellar mission, but that this technology is becoming more likely for use on both commercial and planetary spacecraft.

Commercial lunar mission gives launch contract to ULA

5:56 pm

Capitalism in space: Astrobotic, a private company planning to put a lander on the Moon by 2019, has awarded its launch contract to ULA.

This initial Peregrine lunar lander will fly 77 pounds (35 kilograms) of customer payloads from six nations either above or below the spacecraft’s deck, depending on specific needs. The autonomous landing will use cameras, guidance computing and five Aerojet Rocketdyne-made hypergolic engines to set the lander down on four shock-absorbing legs.

It will stand 6 feet tall (1.8 meters) and have a diameter of 8 feet (2.5 meters).Subsequent missions envision scaling up to payload masses of 585 pounds (265 kilograms). Markets range from scientific instruments to placing mementos on the Moon.

This company had been competing for the Google Lunar X-Prize, but pulled out of the competition when it realized it couldn’t launch by the end of 2018. It continued development, however, and apparently has gathered enough customers to pay for its launch in 2019.

TDRS-M launch moved to August 20

5:47 pm

NASA has decided to delay the launch of its TDRS-M satellite until August 20.

This simplifies their launch schedule, as it allows SpaceX to launch as planned on August 12 and thus not interfere with an August 17 Russian spacewalk that is releasing two satellites from ISS. It will also give them plenty of time to replace the antenna that was damaged during launch prep, in an incident which they still have not described in any detail.

The damage and repair of TDRS-M creates complicated scheduling problems

9:10 am

Because of the launch delay caused by the accident that damaged the antenna of NASA’s TDRS-M communication satellite, requiring its replacement, the agency is now faced with a cascading series of scheduling problems.

They are now aiming for an August 10 launch of TDRS-M on a ULA Atlas 5. This will then force a delay in the August 12 launch of a Dragon capsule to ISS to August 14, which can’t be delayed past August 16 because of a scheduled Russian spacewalk on ISS that must happen on August 17 because it involves the release of two satellites. Making things even more complicated is Dragon’s cargo, which includes mice for a rodent experiment. If it doesn’t occur before August 16, the mice will then have to be replaced with fresh mice, causing further delays.

There is then even the chance that these scheduling problems might impact SpaceX’s scheduled August 28’s launch of the X-37B, as well as ULA’s scheduled August 31 launch of surveillance satellite.

One additional tidbit: This Dragon will be the last unused cargo capsule. All future SpaceX cargo missions will use previously flown capsules.

I should add that these scheduling issues illustrate starkly the growing need for more launch sites. There is money to be made here, fulfilling this need.

Interorbital’s first test rocket, Neptune 1, is almost ready for flight

8:56 am

Capitalism in space: Interorbital, a smallsat rocket company building what they hope will be the world’s smallest and cheapest rocket, have announced that their first test rocket, Neptune 1 Guidance Test Vehicle (N1 GTV), is nearing completion.

During the test flight, the rocket will simulate an orbital launch trajectory by using the main rocket engine’s throttling capability to vary the thrust-to-weight ratio, thus simulating the actual conditions that will be experienced during an orbital launch. After the rocket passes through the transonic phase and Max Q, the engine will gradually throttle down, slowing the rocket until it begins to hover. At this point, the rocket engine will be shut down and the rocket will be allowed to fall. At a safe altitude, a parachute will be deployed for vehicle and payload recovery.

They then plan to follow this with an orbital test flight. No dates however for any of these test flights have as yet been announced.

The endless bands of Saturn

9:39 am

Cool image time. One of the images released by the Cassini science team this week when it announced the first results from the spacecraft’s weekly dives between Saturn and its innermost rings was a short video made from 137 images taken on its first dive on April 26, 2017.

It is absolutely worthwhile to view this video. It begins at Saturn’s north pole, looking down into what appears to be a bottomless vortex, and continues south to almost the equator. Along the way the movie captures what seems to be innumerable horizontal bands across the gas giant’s surface. Not only are do we see the major bands that have been observed from Earth for centuries, there are bands within bands, and bands within those bands. Like a fractal it appears that the deeper you go, the more horizontal jet streams you see.

Like Juno at Jupiter, the mysteries of a gas giant like Saturn is overwhelming. This is a big and very active planet. We understand almost nothing about its weather systems, its atmosphere, and its interior. And this glimpse by Cassini is only that, a mere glimpse. When Cassini’s mission ends in September, it will leave us a treasure trove of knowledge. It will also leave us a much larger library of unanswered questions, all of which will remain unanswered until we can return, decades hence, with new probes..

Tupperware in space!

9:20 am

Capitalism in space: Tupperware and NASA have partnered to provide space-grown gardens an artificial material for roots to grow and be watered.

First flown to the ISS in 2014, the Vegetable Production System, (aka the “Veggie” facility), is an experiment for growing plants in zero gravity in a plastic greenhouse. It consists of a collapsible plastic tent with a controllable atmosphere lit by red, blue, and green LED lamps to promote growth. Since dirt and space travel don’t mix, the seeds are embedded in rooting “pillows” that take the place of soil to retain water and give the roots somewhere to grow.

The problem is that the pillows don’t hold onto water very well, so the hydroponic system keeps drying out unless it’s tended regularly. Given how much it costs to keep an astronaut on the station, time spent watering the lettuce is about as economical as hiring a brain surgeon to mow the lawn, so a team led by Howard Levine at the Kennedy Space Center is working on some upgrades for the system.

One key example is the semi-hydroponic Passive Orbital Nutrient Delivery System (PONDS) being produced by Tupperware. With over 75 years of experience working with food-grade plastics as well as injection molding and other plastic manufacturing processes, Tupperware is producing a new disposable pillow made of plastic mesh that uses capillary forces and unusual geometries to replace gravity and hold water in like a zero gravity sponge while permitting root formation.

In other words, rather than design and built the pillows itself, as it would have in the past, NASA has hired Tupperware to build them. I am willing to bet this is saving NASA both time and money.
