Northrop Grumman successfully test solid rocket booster for ULA’s Vulcan

10:45 pm

Capitalism in space: Northrop Grumman today announced that it has successfully test fired the strap-on solid rocket booster, qualifying it for flight, for use on ULA’s new Vulcan rocket.

In the Jan. 21 static test, the motor fired for approximately 90 seconds, producing nearly 449,000 pounds of thrust to validate the performance capability of the motor, the company said. The firing also verified the motor’s internal insulation, propellant grain ballistics and nozzle in high temperatures.

If all goes right Vulcan will make its inaugural flight later this year.

The slowly disappearing dry ice cap at Mars’ south pole

11:44 am

The Happy Face crater near Mars' south pole
Click for the 2020 full image.

Cool image time! The photo to the right of two images taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) was posted as a captioned image by the orbiter’s science team today.

This crater, dubbed the Happy Face Crater because of the shape of the blobby features within it, is located on the south pole ice cap of Mars, about 200 miles from the south pole itself.

Today’s caption noted how these pictures, taken nine years apart, illustrate the change going on at the Martian south pole.

The “blobby” features in the polar cap are due to the sun sublimating away the carbon dioxide into these round patterns. You can see how nine years of this thermal erosion have made the “mouth” of the face larger. The “nose” consisted of a two circular depressions in 2011, and in 2020, those two depressions have grown larger and merged.

While this caption noted the importance of studying these long term changes in order to understand the evolution of Mars’ climate and geology, it did not give the very specific discovery these changes suggest for Mars globally, a discovery that is actually very significant.

The two ice caps of Mars have some fundamental differences, all presently unexplained. The similarities are obvious. Both have permanent caps of water ice that are presently believed to be in a steady state, not shrinking or growing. Both each winter get covered by a thin mantle of dry ice that sublimates away completely with the coming of spring.

The differences are more puzzling, as shown by the maps of the two poles below.

Curiosity checks out its wheels

1:55 pm

One wheel on Curiosity, as seen in July 2020 and January 2021
For full resolution images, go here and here for the
top image, and here and here for the bottom image.

Having finished a two week look at a sea of sand, Curiosity’ science team has resumed its journey east towards the higher slopes of Mount Sharp.

Before they started out however, they decided to aim the rover’s high resolution mast camera at Curiosity’s wheels to see how they are faring and whether any of the damage that occurred in the early days of the mission has worsened. The photo on the right compares what was seen this week with the damage on the same wheel as seen in July 2020. This is also the same wheel I have posted images of since September 2017.

Not only does there appear to be no appreciable new damage to this wheel in the six months since July, remarkably, a comparison between today’s image and the photo from September 2017, shows little change as well.

In the more than three years since that 2017 photo, Curiosity has crossed Vera Rubin Ridge, crossed the clay unit, climbed up the next ridge to take a look at the incredibly rough terrain of the Greenheugh Pedimont, and then continued across the clay unit on its way to higher and possibly more challenging terrain.

In all those travels it appears this particular wheel has fared rather nicely, accumulating in at least this part little new damage. This bodes well for the rover’s future, as the wheels have been a concern since Curiosity’s first two years on Mars, when engineers found they were experiencing more damage than expected. The travel techniques they have adopted since to protect the wheels appear to be working.

Hints that NASA will redo the SLS static fire test

9:52 am

While NASA has not yet announced any decision on whether it will redo the full static fire test of its SLS core stage — following the January 16th abort — there are hints coming from industry sources that the agency is leaning to doing another test.

According to sources at the agency, program managers are in fact leaning toward conducting a second hot-fire test in Mississippi. Due to the need to obtain more propellant at the test site, conduct minor refurbishment to the vehicle, and possibly change the erratic sensor on Engine 4, the agency estimates it will require about three to four weeks before conducting another test.

Based on that schedule, the actual Artemis 1 unmanned flight, now set for November, will likely have to be delayed one month to December, since after the static fire test it will take several months to disassembly and prep the core stage for shipment to Florida and then reassembly it and prepare it for launch. That November launch date was predicated on a successful completion of the static fire test by January.

NASA and Boeing (the lead contractor building SLS) do not have much schedule margin however. They have begun stacking the solid rocket boosters that strap-on to the core stage. Once this is done the boosters supposedly have a life span of approximately one year, which means the launch must occur by about January ’22 though I would not be surprised if NASA waives that use-by-date if it needs to.

I am in a betting mood this morning. Want to bet SpaceX’s Starship completes its first orbital flight before SLS, even though it has been in development for one tenth the time (2 years vs 20) and for one thirtieth the cost ($2 billion vs $60)? I think the odds right now are very very likely. One way or the other, the race will definitely be neck-and-neck.

SpaceX buys two floating oil rigs for Starship/Super Heavy

9:38 am

Capitalism in space: As has been expected now since June, SpaceX has now officially purchased two floating oil rigs to be used for the launch and landing of its Starship/Super Heavy reusable heavy-lift rocket.

Named Phobos and Deimos, after the two moons of Mars, they are currently undergoing modifications to support Starship launch operations.

SpaceX has long been hinting at future floating launch and landing sites for their Starship launch system. The super heavy lift launch vehicle will have a large blast danger area and pose noise concerns if launched frequently near populated areas. Therefore, sea launch platforms will play a key role in the launch cadence SpaceX plans to reach with Starship, including on-orbit refueling flights for deep space missions and transportation from one place to another on Earth.

Job postings by SpaceX have indicated that work on offshore launch platforms has begun in Brownsville, Texas, near their Starship manufacturing and launch facilities in Boca Chica. Positions included crane operators, electricians, and offshore operations engineers, and several of the job listings specified that the position was part of the company’s Starship program. Job descriptions for these positions included responsibilities like “designing and building an operational offshore rocket launch facility” and required the “ability to work on an offshore platform in Brownsville, Texas.”

Out of work because you live in a fascist Democratic Party-controlled state and have had your job destroyed by their tyrannical policies? Move to Texas and go to work for SpaceX! At the moment at least the United States remains a collection of 50 sovereign states, with the ability of citizens to move from one to the other freely to improve their lives. Some states, such as Texas and Florida, are moving forward under the American concepts of freedom and private enterprise. Others, such as California and New York, are not.

Want to bet which ones will prosper in the coming decade? I pick Texas and Florida. Anyone willing to bet me?

Update on China’s pseudo-private commercial launch industry

9:24 am

Link here. Unlike past Space News articles which generally made believe these privately funded Chinese companies were truly private, the article at the link today is very clear about the close supervision maintained by the Chinese communist government over these companies. They might get funding through private investment capital, but everything they do is approved by their government.

A 2014 central government policy shift opened the Chinese launch and small satellite sectors to private capital. Since then around 20 launch vehicle-related firms have been established in China.

These commercial launch companies are being supported by a national strategy of civil-military fusion. This includes facilitating the transfer of restricted technologies to approved firms in order to promote innovation in dual-use technology. The State Administration for Science, Technology and Industry for National Defense (SASTIND) oversees activities.

Provincial and local governments are also providing support for space companies as they look to attract high-end and emerging technology firms.

The initial focus of the article is on iSpace, also called Interstellar Glory Space, which is planning another fund-raising round. This company, whose Hyperbola-1 solid rocket reached orbit for the first time in 2019, is now designing a liquid-fueled rocket whose first stage will be reusable.

The article also gives a quick review of some of the other Chinese companies.

It is all part of the new colonial movement, the international race to gain dominance in space. The competition is presently fierce, and should only become fiercer based on China’s decision to encourage internal competition.

SpaceX and Rocket Lab complete launches

9:02 am

Capitalism in space: Two successfully launches this morning.

First Rocket Lab used its Electron rocket to launch a German cubesat thought to be a prototype for a Chinese communications constellation, though no information has been publicly released. No recovery attempts were made on the rocket’s first stage.

Then SpaceX successfully completed its 17th Starlink launch and second launch in 2021. This puts about 950 Starlink satellites in orbit. The booster for this flight landed on the drone ship, completing its record eighth flight.

The 2021 launch race:

2 SpaceX
1 Virgin Orbit
1 China
1 Rocket Lab

The U.S. now leads China 4 to 1 in the national rankings.

SLS static fire abort not caused by malfunction but too-tight parameters

1:51 pm

According to NASA today the reason the SLS static fire test cut off after only one minute was because of too conservative margins set in the computer software.

In an update today, however, NASA said it was engine 2 that caused the abort. At that moment, the engines were underdoing a gimble test where they are rotated in different directions just as they must do during ascent to steer the rocket. Actuators in the Thrust Vector Control system that generate the force to gimble an engine are powered by hydraulic Core Stage Auxiliary Power Units (CAPUs). The CAPUs for engine 2 exceeded pre-set test limits and the computer system automatically shut down the test as it was designed to do, but NASA said it would not have been a problem during a launch.

According to NASA’s update,

The specific logic that stopped the test is unique to the ground test when the core stage is mounted in the B-2 test stand at Stennis. If this scenario occurred during a flight, the rocket would have continued to fly using the remaining CAPUs to power the thrust vector control systems for the engines.

Note too that another issue during the test needs resolution:

Initial data indicate the sensor reading for a major component failure, or MCF, that occurred about 1.5 seconds after engine start was not related to the hot fire shutdown. It involved the loss of one leg of redundancy prior to T-0 in the instrumentation for Engine 4, also known as engine number E2060. Engine ignition begins 6 seconds prior to T-0, and they fire in sequence about 120 milliseconds apart. Test constraints for hot fire were set up to allow the test to proceed with this condition, because the engine control system still has sufficient redundancy to ensure safe engine operation during the test. The team plans to investigate and resolve the Engine 4 instrumentation issue before the next use of the core stage.

No decision has been made yet whether they will do another static fire test before shipping the core stage to Florida for launch. They are under a time limit, as they have begun stacking the SLS rocket’s strap-on solid rocket side boosters, and those only have a life expectancy of one year once stacking has begun.

As far as I am concerned, nothing about the development of this rocket makes sense. I would never fly on it no matter how much money was offered to me, and anyone who does must know the terrible risk they take.

More evidence Mars’s glaciers formed across many ice ages

11:26 am

The uncertainty of science: New research using the boulders found on the top of Martian glaciers has now strengthened the evidence that Mars must have undergone many previous ice age cycles going back as much as 800 million years, with those glaciers waxing and waning during each cycle.

This new data helps map the cycles earlier than 20 million years ago, which have been difficult to map out based solely on the orbital data available from Earth and from Mars orbit. The results suggest that before then there were from six to twenty additional cycles during the last 300 to 800 million years.

These numbers are decidedly uncertain. It is likely that there were many more cycles, as suggested by the many layers seen at the edges of the north and south polar ice caps.

Be aware as well that if you read the press release you should know that it falsely implies that this research is the first to map out these ice age cycles. This is not true. All this research has done is provide more evidence for cycles prior to 20 million years ago, cycles that scientists have long believed must have happened based on other data.

In the end, for us to map out the full climate history of Mars will require numerous ice core samples at the planet’s poles, something that will not be possible until people are living and working on Mars routinely.

Mysterious colors on Mars, near the landing site of Europe’s rover

Mysterious colors on Mars
Click for full image.

Cool image time! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) released a new captioned image, which I have cropped and reduced to post here to the right.

The photo was taken October 12, 2020, and shows a small very colorful area on top of an isolated hill. To quote the caption, written by Sharon Wilson:

An isolated, elongated mound (about 1 mile wide and 3.75 miles long) rises above the smooth, surrounding plains. Horizontal layers are exposed at the northern end of the mound, and its surface is characterized by a very unusual quasi-circular pattern with varying colors that likely reflect diverse mineral compositions.

…The origin of this mound is unknown, but its formation may be related to the clay-bearing rocks in the nearby Oxia Planum region.

Chang’e-5’s lunar samples less dense than expected

8:59 am

Because the lunar samples retrieved by China’s Chang’e-5 probe were less dense than expected, it ended up recovering only 3.8 pounds of material rather than the targeted 4.4 pounds.

The probe had estimated the lunar rocks to have a density of 1.6 grams per cubic millimetre, based on data from past missions by other countries, said Pei Zhaoyu, the mission spokesman. Going by that figure, the probe stopped taking samples after just 12 hours, apparently assessing that the target had been reached. “However, from tests, the actual density might not be that high,” Pei told reporters.

This is not a failure, but a discovery. In order to make sure the lander did not recover too much material, weighing too much, they needed to set limits based on the expected weight of the material recovered. That these samples taken from the Mons Rümker volcano complex are lighter than expected reveals something about them. It suggests the lava here was different than lava samples taken elsewhere.

Pioneers and the future

1:31 pm

The asteroid mining ship Dream Watcher docked on the Mars space station.
From Pioneer: The asteroid mining ship Dream Watcher docked
on the Mars space station Landville, c2183.

When I first wrote my sole science fiction book, Pioneer, back in the mid-1980s, I strongly believed (and still do) that for the human race to prosper in space and truly build new civilizations on other worlds, freedom, private enterprise, and courage would be required.

It was for this reason there is absolute no mention of NASA in the book. Unlike most modern movies that idolize this mostly dysfunctional government agency and see it as the only solution for accomplishing anything in space (watch The Martian again to see what I mean), I knew that while government will be strongly involved in space exploration for the foreseeable future, for anything to get done quickly those governments will best step aside and figure out how to let their citizens both freely do it and also own what they do.

This weekend’s aborted SLS static fire test illustrates my point perfectly. Rather than depend on private enterprise to get this rocket built, both George Bush Jr. and Congress decided to give the job to their government bureaucrats. The result has been nothing for now over a decade.

Virgin Orbit’s LauncherOne successfully reaches orbit

9:35 am

Capitalism in space: After eight years of development, Virgin Orbit has finally used its LauncherOne air-launched rocket to successfully put ten satellites into orbit.

After an eight month stand down to resolve issues revealed during the first mission of Virgin Orbit’s LauncherOne rocket, the company made their second orbital launch attempt on Sunday, January 17. The air-launched rocket successfully carried ten CubeSats to their target orbit for NASA’s Educational Launch of Nanosatellites (ELaNa) program.

This makes Virgin Orbit the second smallsat rocket company to achieve orbit, following Rocket Lab. They have beat out a large number of startups, and are now well positioned to gain some of the market share in this new component of the launch market.

They have also made true my September 2016 prediction that Virgin Orbit would complete its first commercial launch before Virgin Galactic’s first suborbital commercial flight, even though Virgin Galactic’s SpaceShipTwo began development eight years earlier.

As for the 2021 launch race, right now only SpaceX and Virgin Orbit have launched in 2021. They are tied for the lead, and also combine to put the U.S. ahead 2 to nothing over everyone else.

SLS core stage static fire test aborts after only one minute

9:23 pm

During the crucial first static fire test of SLS’s core stage yesterday — meant to last a full eight minutes — the booster aborted the test after only one minute.

It’s still too early to know exactly what caused the early shutdown in Saturday’s engine test.

Flight controllers could be heard during the test referring to an “MCF” (a major component failure) apparently related to engine No. 4 on the SLS booster. John Honeycutt, NASA’s SLS program manager, added that at about the 60-second mark, cameras caught a flash in a protective thermal blanket on the engine, though its cause and significance remain to be determined.

Honeycutt said it’s too early to know if a second hot-fire test will be required at Stennis, or if it can be done later at NASA’s Kennedy Space Center in Florida, where the SLS is scheduled to launch the uncrewed Artemis 1 mission around the moon by the end of this year. Similarly, it’s too early to know if Artemis 1 will still be able to launch this year. “I think it’s still too early to tell,” Bridenstine said of whether a 2021 launch for Artemis 1 is still in the cards. “As we figure out what went wrong, we’re going to know kind of what the future holds.” [emphasis mine]

If this engine abort had occurred during a launch, with the two strap-on solid rocket boosters still firing (and no way to turn them off), the entire rocket would have been lost. Thus, for NASA to even consider shipping this core stage to Florida before figuring out the problem and fixing it is downright insane.

They need to figure out what went wrong, fix it, and then test again, even if if means the first unmanned Artemis flight experiences a serious delay. If they don’t then this whole program is proved to be an idiotic sham (something I have believed for about a decade), and should be shut down by Congress and the new President, immediately.

I am reporting this late because this weekend I was out in the country on a caving trip, taking a very much needed break from the truly horrible news of modern America.

SpaceX replacing two engines on Starship prototype #9

1:11 pm

Capitalism in space: After the static fire engine tests earlier this week, SpaceX has decided to replace two of the Raptor engines in its ninth Starship prototype before moving on to its 50,000 foot test flight.

“Two of the engines need slight repairs, so will be switched out,” SpaceX founder and CEO Elon Musk said via Twitter early this morning (Jan. 15).

Musk did not give a target launch date for SN9. But he did say, in another tweet, that it’s “probably wise” to perform another static fire with the vehicle after the engine swap is complete. So a weekend launch for SN9 seems pretty unlikely.

Makes sense, but I must admit a bit of disappointment. I was really hoping that the next flight would occur on the same day NASA attempts its first static fire test of the core stage of SLS. The contrast would have been edifying.

Personally this delay is great for me, as I will be out in the country caving this entire weekend, and would have missed it if it had occurred during the weekend. I will miss the SLS static fire test, but that will be far less interesting (unless something goes wrong).

InSight scientists give up on heat sensor mole

9:25 pm

After another failed attempt earlier this month to dig with the German-made mole on the InSight Mars lander, the science team has decided to abandon all further efforts.

After getting the top of the mole about 2 or 3 centimetres under the surface, the team tried one last time to use a scoop on InSight’s robotic arm to scrape soil onto the probe and tamp it down to provide added friction. After the probe conducted 500 additional hammer strokes on 9 January, with no progress, the team called an end to their efforts.

This means the heat sensor, one of the two instruments carried by InSight, is also a failure, and will not be able to provide any data about the planet’s interior temperature.

From the beginning InSight appears to have been a poorly run and badly chosen project. Other than a weather station, it carried only two instruments, a seismometer and a heat sensor. Its launch was delayed two years when the French attempt to build the seismometer failed and JPL had to take over, fortunately with success. Now the failure of the German-made mole has made the heat sensor a failure.

To send a lander to Mars at a cost of a billion dollars with so little payoff seems in hindsight to have been bad use of money. Plenty of other NASA planetary missions have done far better for far less.

Another professor arrested for hiding ties to China

9:11 pm

An MIT professor has been arrested for hiding his extensive ties to the Chinese communist government, even as he took almost $20 million in grants from the Department of Energy.

According to prosecutors, Gang Chen, a mechanical engineering professor at MIT, has held various positions on behalf of the PRC aimed at promoting China’s technological and scientific capabilities. He allegedly shared his expertise directly with Chinese government officials, “often in exchange for financial compensation,” said prosecutors in the U.S. attorney’s office in Boston.

The Chinese consulate in New York allegedly requested that Chen, a naturalized U.S. citizen, act as an “overseas expert” for the PRC. He was also a member of two talent programs that the PRC has used to place Chinese students at American universities.

This is not the NASA scientist who pled guilty to similar charges yesterday.

It appears to me that the Trump Justice Department is trying to wrap up as many of its cases of academics spying for China as it can before Joe Biden takes over.

Craters in slush on Mars

Dust devil steak across a slushy plain on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on October 27, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was taken not for any particular research project, but as one of the periodic images the camera team needs to take maintain the camera’s proper temperature. When they need to do this, they often will take a picture in an area not previously viewed at high resolution. Sometimes the image is boring. Sometimes they photograph some geology that is really fascinating, and begs for some young scientist to devote some effort to studying it.

In this case the photo was of the generally featureless northern lowland plains. What the image shows us is a scattering of impact craters that appear to have cut into a flat plain likely saturated with ice very close to the surface.

How can I conclude so confidently that these craters impacted into ice close to the surface? The location gives it away.

Starship prototype #9 completes three static fire tests in one day

3:36 pm

Capitalism in space: SpaceX engineers today successfully completed three static fire tests of their Starship prototype #9, all within a space of just over three hours.

The three-engine SN9 vehicle performed its second, third and fourth “static fire” tests in quick succession today (Jan. 13) at SpaceX’s South Texas facilities, near the Gulf Coast village of Boca Chica. The engines lit up briefly at 1:28 p.m. EST (1828 GMT), again at 3:22 p.m. EST (2022 GMT) and then yet again at 4:36 p.m. EST (2136 GMT).

During static fires, engines blaze briefly while a vehicle remains tethered to the ground. SN9 already had one such test under its belt, having completed a short static fire on Jan. 6.

In each case they likely practiced their countdown and fueling procedures, followed by procedures allowing for a quick recycle should they have to abort a countdown but have time to still launch that day.

All this strengthens the reliability and overall design and operation of the rocket as they develop it.

The actual hop could occur, based on road closure announcements, on Friday. It is also possible the company will do additional static fire tests beforehand.

I think it also pertinent to once again compare SpaceX’s development approach to that of Boeing and NASA in their development of SLS. SpaceX is aggressively doing a lot of tests of hardware, continually. They then redesign and rebuild based on those tests. The pace is fast and compressed, and gets things built at a remarkable low cost, considering. It also forces them to design things in a way that makes redesign easy and fast.

Boeing and NASA have done no such tests in building SLS. Instead, they designed it by computer, giving themselves large safety margins in design. This might have reduced or eliminated the need for tests, but it raises the cost of the rocket while stretching out the development time enormously. And it carries great risk. In two days they will attempt their very first static fire test of SLS’s core stage, after almost a decade of development. The actual launch is planned for within a year.

If that static fire test has any issues, the whole SLS project will face serious problems that will, based on its design, be very difficult to fix.

Space Force picks Alabama for its future headquarters

1:21 pm

In a victory for Alabama and its politicians, the U.S. Space Force has chosen the Redstone Arsenal in Huntsville as the location for its future headquarters.

The selection of Redstone Arsenal is a huge win for Huntsville, nicknamed “Rocket City.” U.S. Space Command is currently based at Peterson Air Force Base in Colorado Springs. Alabama was considered a long shot and Colorado was the front runner, given its incumbent status and concentration of military installations and space industry contractors.

U.S. Space Command was established in August 2019 as the military’s 11th unified combatant command. The future headquarters will have approximately 1,400 military and civilian personnel.

While there are many good reasons to pick Huntsville, I guarantee a major factor was the clout exercised by Senator Richard Shelby (R-Alabama), head of the Senate appropriations committee. He will no longer be in charge of the committee with the new Senate, but in his final act as head he likely used it to get the Space Force to move to his state.

This decision however is not yet final. According to government officials, it will take six years (!) to make the move, and already the politicians in Colorado, where the Space Command is presently based, are lobbying to rescind it.

Republican congressman Doug Lamborn, who represents Colorado Springs, sent a letter to President-elect Biden urging him to reverse what he called a “political decision” to move U.S. Space Command to Alabama. “I am disappointed by the horrendous decision to rip U.S. Space Command out of its home in Colorado Springs and move it to a new location,” said Lamborn.

As always, pork is the goal, not defending the U.S. in the most effective manner.

Giant iceberg from Antarctica breaking up

1:10 pm

As should have been expected, the giant iceberg the size of Delaware that had broken from the Antarctic ice pack in 2017 and was drifting directly towards South Georgia Island (a wildlife preserve), is now breaking up without doing any harm to the island itself.

Seawater has been cutting like a knife through A-68A, the enormous Antarctic iceberg drifting in the southern Atlantic Ocean. On January 11, 2021, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 satellite acquired this image showing the remainder of A-68A, along with two large pieces that broke off in December 2020.

The U.S. National Ice Center (USNIC) reported on January 8 that A-68A measured 74 kilometers long and 44 kilometers wide. That equates to an area about twice the size of Houston—still sizable, but quite a bit smaller than its Delaware-sized status in July 2017 when it calved from the Larsen C Ice Shelf. The pieces that broke from A-68A in December (forming A-68D and A-68E) are smaller, but remain large enough to be tracked by the USNIC.

Every report about this, including today’s, waxes eloquently about the terrible threat the iceberg poses to the wildlife on South Georgia Island should it become grounded there, even though all past data, let me repeat, all past data indicated that it would not hit the island but drift around as it broke up.

And, surprise surprise, that is exactly what it has been doing.

Blue Origin announces next New Shepard flight for January 14th

9:11 am

Capitalism in space: Blue Origin today announced that it will launch its fourteenth New Shepard flight tomorrow, at 9:45 am (Central).

This will be the eighth flight for this particular New Shepard capsule.

The link above takes you to their live stream, which will go live 30 minutes before launch. From the press release:

For this mission, the crew capsule will be outfitted with upgrades for the astronaut experience as the program nears human space flight. The upgrades include improvements to environmental features such as acoustics and temperature regulation inside the capsule, crew display panels, and speakers with a microphone and push-to-talk button at each seat. The mission will also test a number of astronaut communication and safety alert systems. The capsule will be outfitted with six seats, including one occupied by Mannequin Skywalker. Also inside the capsule, Blue Origin’s nonprofit Club for the Future will fly more than 50,000 postcards to space and back from students around the globe.

The last flight New Shepard flight was in October. The company had earlier promised manned flights would begin in 2020, but that did not happen. Today’s announcement makes no mention of later flights or future plans.

While I do expect Blue Origin will eventually fly humans on a New Shepard capsule, more and more it looks like it will be more a public relations operation for the company rather than a real profit center. They might make money on it, but the focus of space tourism is shifting to orbital flights. Doing a suborbital flight will still be cool, but it will no longer have the pizazz that it would have had, had the flight been two, three, five, or ten years ago. This shift I think is reflected in the slow pace of New Shepard launches in the past three years.

U.S. and Japan formalize partnership on Gateway

8:53 am

NASA announced yesterday the signing of a formal agreement between the U.S. and Japan detailing exactly how the two countries will partner in the building of NASA’s lunar space station Gateway.

Under an arrangement with Northrop Grumman, Japan also will provide batteries for the Gateway’s Habitation and Logistics Outpost (HALO), the initial crew cabin for astronauts visiting the Gateway. Additionally, Japan is investigating enhancements to its HTV-X cargo resupply spacecraft, which could result in its use for Gateway logistics resupply.

…The agreement also marks NASA’s intent to provide crew opportunities for Japanese astronauts to the Gateway, which will be determined following additional discussions, and documented in a future arrangement.

Japan is one of the seven countries that has also signed the Artemis Accords, which covers the legal and international rights under the project. This new agreement is more technical in nature, outlining who will do what during construction.

Of course, much of this assumes that money will be forthcoming from Congress for Gateway. Right now that budget does not really exist, and its allocation remains quite uncertain.

Capitalism in space: SpaceX’s Starlink internet service has now begun providing its service in the United Kingdom, following approval by the government there.

Because the British government is now also an owner of Starlink’s direct competitor, OneWeb, this creates an interesting conflict of interest that fortunately has so far not impeded SpaceX. We shall have to see whether this changes with time.

Meanwhile, in Russia a similar conflict of interest has resulted in some government action against Starlink.

Russia’s legislative body, the State Duma, is considering fines for individuals and companies in the country that use Western-based satellite Internet services. The proposed law seeks to prevent accessing the Internet by means of SpaceX’s Starlink service, OneWeb, or other non-Russian satellite constellations under development.

…In the Russian-language article, translated for Ars by Robinson Mitchell, members of the Duma assert that accessing the Internet independently would bypass the country’s System of Operational Search Measures, which monitors Internet use and mobile communications. As part of the country’s tight control on media and communications, all Russian Internet traffic must pass through a Russian communications provider.

It is not surprising that Russia would take steps to block Starlink service—the country’s space chief, Dmitry Rogozin, views SpaceX as a chief rival in spaceflight. Rogozin has been critical of both NASA and the US Department of Defense for subsidizing SpaceX through government contracts. (While it is true that SpaceX has received launch contracts from the US government worth several billion dollars, it has also provided launch services at a significant discount compared to other providers.) More recently Rogozin has said Starlink is little more than a scheme to provide US Special Forces with uninterrupted communications.

That the legislation is also aimed at blocking OneWeb however is strange, considering that OneWeb is quite literally Rogozin’s only remaining commercial customer for Roscosmos’s launch services.

In the end, such laws will only end up doing more damage to Russia than to SpaceX. When you don’t allow competition you basically don’t allow any achievements at all. Russia will sink into a second-class status, not because its people are second-class but because its government is.

Tragically it appears the U.S. federal government is now in a race with Russia to the bottom.

Dream Chaser first flight delayed to ’22

3:44 pm

Officials from Sierra Nevada today revealed they have now delayed the first flight of their mini-reusable Dream Chaser shuttle Tenacity until ’22 rather than late this year.

They claim the cause of the delay is the Wuhan flu.

Sierra Nevada has not announced when in 2022 Dream Chaser will attempt to make its first flight, but Lindsey described how pandemic restrictions prevented engineers from being on site for structural testing of the cargo model. Instead, engineers remotely oversaw the tests from a mission control center in Colorado. While the workaround allowed testing to continue, it took three or four times as long as it should have, Lindsey said.

Other delays came from supplier shutdowns due to COVID-19 outbreaks. Technical challenges not related to the pandemic also caused problems, though Lindsey did not elaborate. “All of those things have conspired to move the date a little bit,” Lindsey said.

The first issue is a management decision by the company. I note that SpaceX does not create these kinds of restrictions, and has therefore not experienced any slowdown in its launches or Starship development. It also appears to be experiencing no significant issues with COVID-19 infections.

The second issue is also in a sense a management decision. Sierra Nevada is subcontracting a lot of its work, and thus is at the mercy of other companies. Once again, SpaceX made a decision years ago to do as much as possible in-house. Thus, they are at no one’s mercy, and can push forward even as others cower in fear.

Overall, the pace of development at Sierra Nevada has not been impressive, but then, much of their work is being done by others, such as Lockheed Martin.

The colorful and bright knobs of Ariadnes Colles on Mars

Colorful and bright knob in Ariadnes Colles
Click for full image.

Today’s cool image gives us a sample of the strange colorful hills in an even stranger knobby depression on Mars called Ariadnes Colles. The photo to the right, cropped and color enhanced to post here, was taken on September 10, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It focuses on just one of those colorful hills. The color strip only covers the western half, which is why that is the only part of the hill in color.

Ariadnes Colles is a patch of chaotic terrain 110 by 100 miles in size, located in the southern cratered highlands due south of Mars’s volcano country, at latitude 34 degrees south. What makes this particular patch of chaos distinct from the many others on Mars is that the hills, knobs, and mesas within it are routinely bright and colorful, compared to the darker surrounding terrain. Moreover, as noted in this Mars Express press release for images of Ariadnes Colles from that orbiter,

In contrast to other chaotic terrains … Adrianes Colles is not a water-source region. It is still debated, therefore, whether Ariadnes Colles was formed by the action of water or wind.

The darker material in the southern areas is most likely sand or volcanic ash; some slopes of the flat-topped features have been covered by this dark material that was blown up on the slopes.

The sand or volcanic ash most likely come from the Medusae Fossae Formation several hundred miles to the north, the largest volcanic ash deposit on Mars. The colors on the hill likely come from a variety of minerals.

The overview map below shows the entire patch, with the location of the hill above indicated by the white dot in the red rectangle that shows the full image location.

NASA moves up static fire test of SLS core stage

10:50 pm

NASA today announced that it has rescheduled the full duration static fire engine test of the core stage of SLS’s first stage, moving it up one day to this coming Saturday, January 16th.

During the test, engineers will power up all the core stage systems, load more than 700,000 gallons of cryogenic, or supercold, propellant into the tanks and fire all four engines at the same time.

If all goes right, that test will last about 8 minutes, the full time those engines are intended to fire during launch.

For SLS a lot rides on this test. Should anything go wrong, it will likely delay the launch, presently scheduled for November (though there are rumors this date is no longer likely). And since we now have a new administration taking power that is also linked politically with the previous Obama administration that was generally uninterested in SLS, a failure during this test could very well signal the death knell for this vastly over-budget and far behind schedule project.

For SLS to survive, this test must succeed, and fire for its full duration.
