Jupiter as seen by Hubble in 2019
Click for full image.

The Hubble science team today released a new global image the telescope took of Jupiter on June 27, 2019. The photograph on the right is that image, reduced and cropped to post here. As noted by the press release about the Great Red Spot,

The Great Red Spot is a towering structure shaped like a wedding cake, whose upper haze layer extends more than 3 miles (5 kilometers) higher than clouds in other areas. The gigantic structure, with a diameter slightly larger than Earth’s, is a high-pressure wind system called an anticyclone that has been slowly downsizing since the 1800s. The reason for this change in size is still unknown.

A worm-shaped feature located below the Great Red Spot is a cyclone, a vortex around a low-pressure area with winds spinning in the opposite direction from the Red Spot. Researchers have observed cyclones with a wide variety of different appearances across the planet. The two white oval-shaped features are anticyclones, like small versions of the Great Red Spot.

Another interesting detail is the color of the wide band at the equator. The bright orange color may be a sign that deeper clouds are starting to clear out, emphasizing red particles in the overlying haze.

In many ways Hubble’s images of Jupiter are comparable to those taken by Juno, except that Hubble can’t zoom in as close.

Crater on the Basement of Mars

12:05 pm

Crater in the bottom of Hellas Basin
Click for full image.

Cool image time! In the July release of images from the high resolution camera of Mars Reconnaissance Orbiter (MRO) was the image to the right, cropped to post here, showing what I suspect is a relatively young crater located in the lowest part of Hellas Basin, what I call the bottom of Mars.

Though this crater is not located at the lowest point in Hellas, it is not far off from there. What makes it important to geologists are two facts. First, there are not a lot of craters in Hellas, which helps indicate it is a relatively young feature. Second, and more important, the impact has made accessible material from below the surface, indicated by the different colors in this image. From this information they can better constrain their theories about the Basin’s formation and where it fits in Mars’s overall geological history.

Make sure you take a look at the full photograph by clicking of the image, and compare it with the earlier Hellas Basin images I posted here. The surface of Hellas appears to have a lot of flow features, as if it was laid down by volcanic activity, or by the motion of water that covered it. In either case that would explain the overall lack of craters.

FCC streamlines and cuts fees for smallsat licensing

9:09 am

Capitalism in space: In an effort to ease its bureaucratic obstacles to private enterprise, the FCC has streamlined its licensing process for new smallsats, while cutting its licensing fees by more than 90%.

Under the optional licensing regime, which stands to take effect this year, smallsat operators with spacecraft that meet certain criteria will be able to obtain a spectrum license about twice as fast and pay only $30,000 instead of nearly $500,000. A maximum of 10 satellites at a time can be licensed under the streamline process.

…Operators will be able to use the streamlined licensing for satellites that weigh 180 kilograms or less, operate below 600 kilometers (or have propulsion) and will deorbit within six years, among other criteria.

One component of these new regulations is that they require new smallsats to never be smaller than 10 centimeters on their smallest dimension, thus essentially forbidding the launch of nanosats smaller than that.

Video of Long March 2C grid fins used in July

9:01 am

China Central Television has released a very short video showing the grid fins used during the July 26 launch of China’s Long March 2C rocket in order to better control the descent of that rocket’s expendable first stage.

I have embedded the video below the fold. It shows the four grid fins unfolding, but not much else. It also reveals that the Chinese very clearly were inspired by SpaceX’s Falcon 9 grid fin design.

The video also gives me the impression that the Long March 2C first stage does not have any thrusters, which were SpaceX’s primary mode for controlling its first stages, the grid fins added later when they understood better the engineering required. Thus I suspect that the fins were not very successful in controlling that stage’s flight.

Nonetheless, the Chinese are doing these tests during operations, which means they are only a first step on a path to success.

Vector gets Air Force launch contract

8:50 am

Capitalism in space: Vector has signed its first Air Force launch contract for an orbital cubesat launch in 2021.

The Air Force must know something about Vector’s rocket development that we don’t. The company had planned a suborbital test launch for March/April, delayed it until June, and has still not flown it. These delays put the company behind its original launch schedule by a considerable amount, which originally had called for its first orbital launch in 2018.

Hopefully we shall soon see some actually progress from Vector. At the moment however their lack of launches has allowed a number of other smallsat rocket companies to gain on them from behind.

Yutu-2 and Chang’e-4 go to sleep again

8:42 am

Yutu-2's travels

Both Yutu-2 and Chang’e-4 have been put in dormant mode after completing their eighth lunar day on the far side of the Moon.

The article at the link provides a lot of new details about what both spacecraft have learned and done since they landed, including a nice detailed map showing Yutu-2’s exact path during those eight lunar days. The image to the right, reduced to post here, was taken by Yutu-2, and shows the rover’s tracks during what appears to be its seventh lunar day. It appears that the rover periodically stopped and did a pirouette, probably to obtain a 360 degree mosaic of the surrounding terrain.

Yutu-2’s travels have tended west from Chang’e-4, and on its eighth lunar day it continues that route, traveling 271 meters. After a period of short traveling days, they have now upped the distance traversed by a considerable amount. Since the planned nominal mission for both spacecraft had been three lunar days, both are demonstrating that the Chinese have figured out how to do this, and are now pushing Yutu-2 hard as a result.

The article vaguely describes some of the science obtained so far, but in general the Chinese remain tight-lipped about most of their discoveries.

ULA’s Atlas 5 launches military communications satellite

8:07 am

Early this morning ULA used its Atlas 5 rocket to successfully launch an Air Force military communications satellite.

This was the third ULA launch this year, which means they remain off the leader board below. This number of launches is also below the pace set the last two years, where they completed eight launches per year.

The leaders in the 2019 launch race:

12 Russia
11 China
10 SpaceX
6 Europe (Arianespace)
4 India

The U.S. now leads in the national rankings 17 to 12.

Smallsat rocket company Orbex signs two launch deals

1:05 pm

Capitalism in space: The new smallsat rocket company Orbex today announced the signing of two different launch deals, one with In-Space and the other with Innovative Space Logistics both with companies focused on procuring launch services for smallsat companies.

Both are for its as yet untested Prime rocket, which they hope to launch by 2021 from the United Kingdom’s new spaceport in Scotland.

Cygnus undocks from ISS, will remain in orbit for five more months

10:55 am

Northrop Grumman’s Cygnus cargo capsule has undocked from ISS, but will remain in orbit until December.

First, the capsule, dubbed the S.S. Roger Chaffee, will deploy a bunch of cubesats and nanosats. Then,

Northrop Grumman plans several months of long-duration spaceflight experiments using the Cygnus spacecraft after release of the CubeSats. Four miniaturized control moment gyroscopes are flying on the cargo freighter for the first time, and engineers will assess their performance in controlling the spacecraft’s pointing without consuming rocket fuel.

Ground teams also want to evaluate how the Cygnus spacecraft’s avionics function on a long-duration mission, and Northrop Grumman plans to demonstrate dual Cygnus operations for the first time after the launch of the company’s next resupply mission — NG-12 — in October.

Northrop Grumman has gotten a NASA contract to use Cygnus as the basis for the habitable module of NASA’s Lunar Gateway project, and this extended flight is a way to test the engineering for that module now during operations.

Though I continue to have many doubts about Gateway, I laud Northrop Grumman for this approach. It speeds things up and saves money.

India’s new smallsat rocket gets its first launch contract

10:48 am

The new colonial movement: India today signed its first customer for its new and still untested SSLV rocket, designed to provide orbital launch services for the burgeoning smallsat market.

Spaceflight announced Aug. 6 that it will purchase the first commercial launch a new Indian vehicle scheduled to make its debut later this year. Spaceflight said it will launch payloads for an undisclosed U.S. satellite constellation customer on a flight of the Small Satellite Launch Vehicle (SSLV), a derivative of the existing, larger Polar Satellite Launch Vehicle (PSLV). The launch is scheduled for later this year and will be the second for the SSLV after a demonstration launch expected no earlier than September.

While the companies didn’t announce the customer for the mission, a July 25 filing with the Federal Communications Commission by Earth imaging company BlackSky Global sought a license for four of its satellites it said would launch on the SSLV in November 2019. The applications said the satellites would be deployed into two orbital planes, consistent with Spaceflight’s announcement.

While this Indian rocket is hardly a private operation, it has no military component, as do the new Chinese smallsat companies. ISRO, India’s space agency, is wholly civilian with no apparent ties to its military, as far as I know. Its goal is to purely make money and grab market share.

At the same time, the use of government funds to develop this rocket gives India the same advantage that China’s smallsat companies have over the privately funded rockets from the U.S. It allows them to set lower prices and undercut the competition.

Rocket Lab to attempt recovery and reuse of Electron 1st stage

10:37 am

Capitalism in space: Faced with stiff competition from both other smallsat rocket companies as well as the big players like SpaceX, Rocket Lab has announced that they are going to try to recover the first stages of their Electron rocket for later reuse.

Their plan is to use the atmosphere and parachutes to slow the stage down as it returns to Earth, and then have a helicopter snag it and land it on a ship.

They had looked into the idea of vertically landing it, like SpaceX does with its Falcon 9, but found it would make their rocket to big and expensive.

This plan is not as radical as it sounds. The Air Force did something similar for almost a decade in the 1960s to recover film from its surveillance satellites.

SpaceX and Arianespace complete successful launches

9:58 pm

Today, as I was giving my lecture in Denver, both Arianespace and SpaceX successfully completed launches.

SpaceX put a commercial communications satellite in orbit. The first stage was not recovered, but this was intended. The company however was successful in catching one half fairing in the giant net of its recovery ship Mrs. Tree., the second time they have done so.

Arianespace used its Ariane 5 rocket to launch a commercial communications satellite and a European Space Agency data relay satellite.

The leaders in the 2019 launch race:

12 Russia
11 China
10 SpaceX
6 Europe (Arianespace)
4 India

The U.S. now leads Russia 16 to 12 in the national rankings.

SpaceX offers new cut-rate prices for smallsats

6:18 am

Capitalism in space: SpaceX yesterday announced that the company is now offering new cut-rate prices to launch smallsats on its rockets.

The company is offering rideshare opportunities for satellites weighing up to 150kg at the price of $2.25 million. The rideshare-only missions, flying aboard the company’s workhorse Falcon 9 rocket, will launch at regularly scheduled intervals. “SpaceX is committed to serving the commercial market as it grows and changes,” a spokesperson for the company said. “And we believe we can address the needs of small satellite operators by offering reliable, cost-effective access to orbit through regularly scheduled, dedicated rideshare missions.”

The company has previously flown rideshare missions using its Falcon 9 rocket, but those flights were organized and integrated by a third-party provider, Spaceflight Industries. Now SpaceX will do all of that work directly for customers

This move makes SpaceX’s smallsat prices very competitive. It also makes it easier for smallsat companies to bypass China’s semi-private commercial companies, thus avoiding the risk of China stealing their technology.

Water bears on the Moon!

6:05 am

A digital library carried by the Israeli lunar lander, Beresheet, that crashed on the Moon in April also carried with it dehydrated tardigrades, also called water bears.

Spivack had planned to send DNA samples to the moon in future versions of the lunar library, not on this mission. But a few weeks before Spivack had to deliver the lunar library to the Israelis, however, he decided to include some DNA in the payload anyway. Ha and an engineer on Spivack’s team added a thin layer of epoxy resin between each layer of nickel, a synthetic equivalent of the fossilized tree resin that preserves ancient insects. Into the resin they tucked hair follicles and blood samples from Spivack and 24 others that he says represent a diverse genetic cross-section of human ancestry, in addition to some dehydrated tardigrades and samples from major holy sites, like the Bodhi tree in India. A few thousand extra dehydrated tardigrades were sprinkled onto the tape used to secure the lunar library to the Beresheet lander.

The promising thing about the tardigrades, says Spivack, is that they could hypothetically be revived in the future. Tardigrades are known to enter dormant states in which all metabolic processes stop and the water in their cells is replaced by a protein that effectively turns the cells into glass. Scientists have revived tardigrades that have spent up to 10 years in this dehydrated state, although in some cases they may be able to survive much longer without water. Although the lunar library is designed to last for millions of years, scientists are just beginning to understand how tardigrades manage to survive in so many unforgiving environments. It’s conceivable that as we learn more about tardigrades, we’ll discover ways to rehydrate them after much longer periods of dormancy.

They suspect that the digital library probably survived the crash, which means the dehydrated water bears did also.

Don’t expect the Moon to be overrun by tardigrades. However, it will be a very interesting discovery if we find, years hence when explorers finally can recover that digital library, that the tardigrades can be re-hydrated and come back to life.

Proton launches military communications satellite

8:44 pm

A Russian Proton rocket today successfully launched a military communications satellite into orbit.

This was the third Proton launch this year, the most since 2017. It also put Russia in the lead for most launches in 2019, the first time that country has been in first since 2015:

12 Russia
11 China
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. still leads Russia in the national rankings, 15-12.

The great storms of Jupiter

9:12 am

The Great Red Spot and its trailing storms
Click for full image.

Close-up

During its most recent close approach of Jupiter, Juno took the above image of the gas giant’s Great Red Spot from a distance of 26,697 miles above the cloud tops. As noted at the link,

This view highlights the contrast between the colorful South Equatorial Belt and the mostly white Southern Tropical Zone, a latitude that also features Jupiter’s most famous phenomenon, the persistent, anticyclonic storm known as the Great Red Spot.

Just for fun, I cropped out at full resolution the bright storm just to the west of the Great Red Spot, as shown on the right.

It is important to understand the vastness of this image’s scale. You could almost fit two full Earths within the Great Spot. The close-up covers only a slightly smaller range of size. Thus, that tiny bright storm would be the largest hurricane ever seen on Earth, able to cover almost the entire Pacific Ocean.

First images from Chandrayaan-2

8:29 am

Earth from Chandrayaan-2

India yesterday released the first images taken by its lunar orbiter/lander/rover Chandrayaan-2, taken from Earth orbit of the Earth.

The image on the right is one example, and was taken mostly for engineering purposes. All the images (available here) demonstrates that the spacecraft’s camera is working properly, and it can orient itself accurately.

They now hope to put the spacecraft into lunar orbit on August 20th, with the landing attempt set for September 7th, after they have lowered that lunar orbit sufficiently.

Russia denies OneWeb permission to operate in Russia

9:04 am

Russian government agencies this week denied permission to OneWeb to operate and provide internet services within Russia, even though Russia is launching a large bulk of OneWeb’s satellite constellation.

One agency denied them permission to use certain radio frequencies. Another has said no because it claims the satellites could be used for espionage. The first denial, in 2017, came from Roscosmos, which is also the agency launching OneWeb’s satellites.

The latest refusal of OneWeb was a sign that the country’s authorities remain keen to continue tightening their control of internet access, said Prof Christopher Newman at Northumbria University.

“[Satellite internet] presents an existential strategic threat to their trying to limit internet activity within their boundaries,” he told the BBC. “There are going to be large swathes of Russian territory… that are going to become very dependent on internet from space.”

Russia continues its sad slide back to Soviet-style authoritarianism and poverty.

SpaceX to launch Super Heavy/Starship from Florida

8:58 am

Capitalism in space: According to a SpaceX environmental report submitted to NASA, the company now plans to launch Super Heavy/Starship missions from Florida, and only Florida.

The report details the work they want to do at launch complex 39A, where they presently launch both Falcon 9s and Falcon Heavies.

The facilities will be able to support up to 24 Starship/Super Heavy launches a year, the company said in the report, with a corresponding decline in Falcon launches from the complex. “Due to the higher lift capability, Starship/Super Heavy could launch more payloads and reduce the overall launch cadence when compared to Falcon 9 and Falcon Heavy,” the report states.

SpaceX ruled out performing Starship/Super Heavy launches from its other two existing launch sites, Space Launch Complex 40 at Cape Canaveral and Space Launch Complex 4 at Vandenberg Air Force Base in California. The company ruled out the sites because they would require more modifications and because the Vandenberg site didn’t support trajectories for the “vast majority” of missions.

Falcon Heavy launches especially will vanish once this new rocket is operational, as it will be cheaper to use and have greater capabilities, should it succeed in being everything SpaceX hopes it to be.

Bezos provides 1st BE-4 engine update in more than a year

8:49 am

Yesterday Jeff Bezos posted the first status update since last spring on the development of the BE-4 rocket engine by Blue Origin, posting one image and stating that the engine testing continues.

According to his post, the engine had just completed a full power test, and has been accumulating test time.

This update is very reassuring, especially following such a long period of silence, beginning in April 2018. Before that Blue Origin had provided somewhat regularly updates.

In reviewing my past posts, it appears that the updates more or less ceased once ULA announced its decision to use the BE-4 in its Vulcan rocket. I now suspect the earlier updates were aimed more at ULA than the public, and once the decision was made Blue Origin returned to its more traditional tight-lipped approach.

NASA/NOAA failure report for GOES-17: The government screwed up

12:21 pm

A joint investigation by NASA and NOAA into the failure issues on the GOES-17 weather satellite, launched in March 2018, have determined that the problem with the Advanced Baseline Imager (ABI), the satellite’s main instrument, was caused by

a blockage in the instrument’s loop heat pipes, which transfer heat from the ABI electronics to its radiator. The blockage restricted the flow of coolant in the loop heat pipes, causing the ABI to overheat and reducing the sensitivity of infrared sensors.

You can read the short full report here [pdf].

My immediate thought in reading the press release above was: So a blockage caused the problem. What caused the blockage? Was it a design failure or a construction mistake? Or what? The answer to this question is even more critical in that the same issues have been identified in GOES-16, though not as serious.

Moreover, GOES-16 and GOES-17 are the first two satellites in a planned new weather constellation of four satellites. Knowing who or what caused this blockage prior to construction and launch of the two later satellites is critical.

I immediately downloaded the report and read it, thinking it would name the contractor and the cause of the blockage.

Nope. The report is remarkably vague about these details, which the report justifies as follows:

The report is NASA sensitive, but unclassified (SBU), because it contains company proprietary information. The report also contains information restricted by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR). This summary report provides an overview of publicly releasable information contained in the full report.

In other words, this report is an abridged version of the full report, which is being kept classified because it contains both commercial proprietary information and information that if released would violate ITAR regulations designed to keep U.S. technology from reaching foreign hands.

What this public report does imply in its recommendations, in a remarkable vague way, is that the problem occurred because the government had demanded changes during construction that forced significant redesigns by the contractor, none of which were then given sufficient review.

Or to put it more bluntly, NOAA and NASA, the lead agencies in the GOES project, screwed up. They forced the contractor to make changes, probably very late in the process, resulting in inadequate review of those changes.

The recommendations put forth many suggestions to institute a more detailed review process, should late changes in the construction of the next two GOES satellites be required or demanded. Such recommendations however will only further delay and increase the costs for building those satellites. Since the entire constellation went overbudget significantly (from $7 billion initially to $11 billion), and has also been very late (see this GAO report [pdf]), this means that the next two satellites will be even later and more expensive.

For NASA and NOAA this is just fine, pumping more money into each agency. For the taxpayer it is terrible.

The whole process should be dumped. Give the job of building these satellites to the private sector, entirely. Get these agencies out of the construction business. The only contribution they are presently adding is more cost and delays, while also causing satellite failures.

Landowners in Scotland sign lease for spaceport

10:16 am

The new colonial movement: The landowners for a planned commercial spaceport in Sutherland, Scotland, have now signed a 75-year lease with the spaceport developers.

Construction of the project is anticipated to begin next year with the UK Space Agency (UKSA) providing a grant of £2.5million to HIE, as well as funding two launch companies who will use the facility once it is operational.

I highlight the word “UK”, which stands for the United Kingdom, because that word indicates another very big unstated obstacle to this spaceport. The UK as a whole has voted to leave the European Union. The population of Scotland however voted against that exit, and its leaders have indicated that they will not go along with the plans of the new British prime minister, Boris Johnson, to exit, deal or no deal. In fact, they have indicated that they would instead want to leave the United Kingdom in that case.

Should that happen, the future of this spaceport will be threatened. The deals that have made it possible have come from the UK space agency, a entity that Scotland would no longer belong should it leave the United Kingdom.

Chinese test microsat deorbits and crashes into Moon

10:05 am

The new colonial movement: A Chinese tiny smallsat, sent to lunar orbit to test the technology of such microsats, has been deorbited and allowed to crash into the far side of the Moon.

The micro satellite crashed into a predetermined area on the far side of the Moon at 10:20 p.m. on July 31 (Beijing Time), the center said Friday.

Weighing 47 kg, Longjiang-2 was sent into space on May 21, 2018, together with the Chang’e-4 lunar probe’s relay satellite “Queqiao,” and entered the lunar orbit four days later. It operated in orbit for 437 days, exceeding its one-year designed lifespan.

The development of the micro lunar orbiter explores a new low-cost mode of deep space exploration, said the center. The micro satellite carried an ultra-long-wave detector, developed by the National Space Science Center of the Chinese Academy of Sciences, aiming to conduct radio astronomical observation and study solar radiation.

China might be stealing a lot of the space technology it is using to make it a major space power, but it is also doing a fine job of refining and improving that technology. Its capability to do practically anything in space as well if not better than anyone else continues to grow.

And with their government using its space effort as a management test for determining the best individuals to promote into the government’s power structure, do not expect their space effort to wane anytime in the near future.

Parker data downloaded from first two orbits

9:28 am

The science team for the Parker Solar Probe has completed the download of all data gathered during the spacecraft’s first two solar orbits.

On May 6, 2019, just over a month after Parker Solar Probe completed its second solar encounter, the final transmission of 22 gigabytes of planned science data — collected during the first two encounters — was downlinked by the mission team at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland.

This 22 GB is 50% more data than the team had estimated would be downlinked by this point in the mission — all because the spacecraft’s telecommunications system is performing better than pre-launch estimates. After characterizing the spacecraft’s operations during the commissioning phase, which began soon after launch, the Parker mission team determined that the telecom system could effectively deliver more downlink opportunities, helping the team maximize the download of science data.

The team has capitalized on the higher downlink rate, instructing Parker Solar Probe to record and send back extra science data gathered during its second solar encounter. This additional 25 GB of science data will be downlinked to Earth between July 24 and Aug. 15.

Don’t expect any immediate press conferences announcing results. It will take them time to analyze this batch, and they will probably want to do a few more orbits before coming to any conclusions.

Chandrayaan-2 successfully completes 4th orbit burn

9:23 am

The new colonial movement: India’s lunar orbiter/lander/rover Chandrayaan-2 today successfully completed its fourth engine burn, this time raising its orbital apogee to 89,472 kilometers (55,595 miles).

The next burn is scheduled for August 6, when the spacecraft’s orbit brings it back down to its perigee.

By September they expect to raise that apogee high enough so that it is within the Moon’s gravitational sphere of influence, when they will be able to put it the spacecraft into lunar orbit.

Bezos sells another $1.8 billion in Amazon stock

10:41 am

Capitalism in space? Jeff Bezos last night sold just under a million shares of his Amazon stock, earning in cash an estimated $1.8 billion.

Unlike a similar sale of stock by Bezos last April, there is no statement from Bezos about what he intends to use the money for. Then Bezos made it clear that he intended to periodically sell his stock to raise money for Blue Origin and its various space ventures. Today’s sale was the third since he said this, with total earnings from all three sales totaling about $4 billion, and all are likely aimed at funding that space company.

I might have increasing concerns about Blue Origin because of what appears to be a stalled rollout of New Shepard and New Glenn, but with deep pockets such as this, it would be surprising if the company fails to achieve its goals.

New NASA development contracts include refueling work by SpaceX

10:26 am

Capitalism in space: Yesterday NASA announced a bunch of partnership agreements with thirteen companies, where those companies will get NASA assistance at no cost to help them develop new engineering that would aid future solar system exploration.

The partnerships covered everything from helping small companies develop new space electronics, heat shields, and new types of thrusters to helping Blue Origin develop the technology for for landing on the Moon.

An article at Ars Technica today about this NASA announcement focused specifically on the SpaceX deal, mainly for its important political implications.

The partnership will have two different NASA agencies helping SpaceX develop the refueling technology it needs for Starship to reach Mars. The key is that this deal has NASA openly supporting technologies that are in direct competition with its own SLS rocket. When such research work was proposed back in 2010, it was opposed quite strongly by past agency officials as well as powerful politicians in Congress, for exactly that reason.

It was a contentious time in space policy, as the White House was pushing for more funding for new space companies—and new space ideas such as fuel-storage depots—while Congress wanted to keep NASA in the rocket-building business.

Eventually, Congress got the upper hand, putting NASA on track to build the large SLS rocket at a development cost of more than $2 billion a year. The rocket program mostly benefited the Alabama space center and was championed by Alabama State Senator Richard Shelby. The potential of in-space fuel storage and transfer threatened the SLS rocket because it would allow NASA to do some exploration missions with smaller and cheaper rockets. As one source explained at the time, “Senator Shelby called NASA and said if he hears one more word about propellant depots he’s going to cancel the Space Technology program.”

The line from other NASA officials was that as a technology, propellant depots were not ready for prime time. In 2011, former NASA Administrator Mike Griffin and current Executive Secretary of the National Space Council Scott Pace—both SLS advocates—wrote a withering criticism of the technology for Space News.

Now however the Trump administration is helping SpaceX develop refueling for Starship, which if successful will help make SLS irrelevant. This is more evidence that the Trump administration is laying the political groundwork that will allow it to shut SLS down, actions that were impossible in the political culture of Washington only two years ago.

This quote in the article is probably the most startling of all:

“Administrator Bridenstine is clearly executing on President’s Trump’s guidance to increase commercial public-private-partnerships at NASA,” Miller, now chief executive of UbiquitiLink, told Ars. “The game-changing technology that NASA has discovered is capitalism. This program proves NASA leadership has figured out the future is reusability mixed with commercial public-private-partnerships.” [emphasis mine]

Imagine that. An American government agency has learned that capitalism is the way to go. Will wonders never cease?

Update: See this related Ars Technica article: The SLS rocket may have curbed development of on-orbit refueling for a decade (Hat tip reader Calvin Dodge.)

Suborbital rocket company has launch failure

9:59 am

Capitalism in space: Gilmour Space Technologies, one of the numerous new rocket companies aimed at capturing the emerging smallsat market, experienced a launch failure on July 29 just prior to lift-off of its suborbital rocket.

At T-7 seconds to launch, the test rocket suffered an anomaly that resulted in the premature end of the mission. Initial investigations show that a pressure regulator in the oxidiser tank had failed to maintain the required pressure, and this caused the upper half of the rocket to be ejected as helium escaped.

On the positive side, there were no explosions due to the safe nature of hybrid rocket engines, and no observable damage to the engine. (The white plume seen here is steam.) Moreover, despite failure to launch, the team did successfully test Gilmour Space’s mobile launch platform and mission control centre, which had journeyed over 1,800 km to the test site.

It appears the failure was from a piece of equipment provided by an outside contractor.
