NASA engineers today returned the agency’s SLS rocket to its launchpad for its next attempt to complete a full dress rehearsal countdown, completing the journey from the vehicle assembly building in 8 hours.
They will spend the next two weeks preparing the rocket for that dress rehearsal, with the two-day countdown to begin no no earlier than June 17th.
The new colonial movement: Using its Long March 2F rocket, China has successfully launched three astronauts into orbit for a six month mission to its Tiangong space station.
The crew will be transported to the station in China’s Shenzhou capsule, docking about six hours after launch. During this mission China will also launch the last two large modules planned for the station, completing its initial construction by the end of the year.

Dmitry Rogozin, the head of Roscosmos, revealed today that he has issued orders for the scientists running the Spektr-RG telescope to figure out how to take over operations of the German instrument on the telescope.
“I gave instructions to start work on restoring the operation of the German telescope in the Spektr-RG system so it works together with the Russian telescope,” he said in an interview with the Rossiya-24 TV channel.
The head of Roscosmos said the decision was necessary for research. “They – the people that made the decision [to shut down the telescope] don’t have a moral right to halt this research for humankind just because their pro-fascist views are close to our enemies,” he said.
The Europeans had shut down operations when it broke off all of its space partnerships with Russia, following the Ukraine invasion and the decision of Russia to confiscate 36 OneWeb satellites rather than launch them as it was paid to do.
Capitalism in space: Blue Origin’s suborbital reusable spacecraft today completed its fifth passenger flight and 21st overall, carrying six people.
It is time for another sunspot update! On June 1 NOAA released its monthly update of its graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere. As I do every month, I have posted it below, having added some addition details to provide a larger context.
In May the sunspot activity on the Sun almost literally exploded, producing some of the strongest solar flares in years as well as the most sunspots since the previous solar maximum in 2014. On several days there were as many as eight sunspot groups on the Sun, with one so large that it was visible to the naked eye on Earth (if viewed properly with a protective filter).

Capitalism in space: At a ceremony today that included officials from the government, the private commercial company ANANTH opened India’s first private satellite manufacturing facility.
Located at Karnataka Industrial Area Development Board Aerospace Park, Bengaluru, the new establishment is equipped with clean rooms for spacecraft sub-systems manufacturing and is large enough to cater to four spacecraft simultaneously.
This unveiling is part of India’s effort to transition from a government-built space effort to one run by the private sector. In the past all satellite construction in India was designed, managed, and owned by India’s space agency ISRO. This facility will now take over that function, and do so not only for ISRO but for any private company that wishes to have a satellite built.

Since early February the Mars Rover Perseverance has been toting with it a small rock in its front left wheel, as shown in the image to the right, cropped and reduced to post here and taken by the rover’s left hazard avoidance camera on February 6, 2022.
From an update today by the Perseverance science team:
Back on sol 341— that’s over 100 sols ago, in early February— a rock found its way into the rover’s front left wheel, and since hitching a ride, it’s been transported more than 5.3 miles (8.5 km). This rock isn’t doing any damage to the wheel, but throughout its (no doubt bumpy!) journey, it has clung on and made periodic appearances in our left Hazcam images.
You can see the most recent photo of the rock, taken on May 26, 2022, here. It is very clear that the rock’s repeated tumbling inside the wheel well has worn away its sharp edges as well as reduced its overall size. Given enough time its surface could even become somewhat smooth.
As the update notes, when this rock finally drops off it will create a potential mystery for future geologists, who if they are not aware that Perseverance moved it, will wonder how it got where it was, being geologically out-of-place in its new location.
Capitalism in space: NASA yesterday awarded separate contracts to two different companies, Axiom and Collins Aerospace, to build spacesuits for its astronauts, either when they do spacewalks in space or when they are exploring the lunar surface.
The contract enables selected vendors to compete for task orders for missions that will provide a full suite of capabilities for NASA’s spacewalking needs during the period of performance through 2034. The indefinite delivery and indefinite quantity, milestone-based xEVAS contract has a combined maximum potential value of $3.5 billion for all task order awards. The first task orders to be competed under the contract will include the development and services for the first demonstration outside the space station in low-Earth orbit and for the Artemis III lunar landing.
Each partner has invested a significant amount of its own money into development. Partners will own the spacesuits and are encouraged to explore other non-NASA commercial applications for data and technologies they co-develop with NASA.
More information can be found in each companies’ press release, located here (Axiom) and here (Collins).
These commercial contracts replace NASA’s own failed effort to make its own Artemis spacesuits, which spent fourteen years and more than a billion dollars before being abandoned by the agency because wouldn’t be able to deliver anything on time.
The contracts also continue NASA’S transition — as recommended in my 2017 policy paper Capitalism in Space [pdf] — from a failed space contractor to merely being the customer buying products from the commercial sector. The result is we now have a vibrant and ever growing private space sector with products available quickly and cheaply not only for NASA, but for others. The Axiom press release illustrates these facts with this quote:
The Axiom spacesuit is key to the company’s commercial space services. This new NASA contract enables Axiom to build spacesuits that serve the company’s commercial customers and future space station goals while meeting NASA’s ISS and exploration needs.
Capitalism in space: NASA has now announced that it is buying five additional manned missions to ISS from SpaceX, beginning in ’26.
This new contract is in addition to a February ’22 NASA award that purchased three more Dragon flights.
After a thorough review of the long-term capabilities and responses from American industry, NASA’s assessment is that the SpaceX crew transportation system is the only one currently certified to maintain crewed flight to the space station while helping to ensure redundant and backup capabilities through 2030.
The current sole source modification does not preclude NASA from seeking additional contract modifications in the future for additional transportation services as needed.
The press release repeatedly makes it clear that NASA very much wishes to buy tickets on Boeing’s Starliner, but until it is declared operational it must give its business to SpaceX. Once Starliner begins flying, NASA will then buy seats on it and alternate between the two companies. Until then however this new SpaceX contract guarantees NASA enough flight capacity to keep ISS occupied, even if Starliner gets further delayed.
Regardless, Boeing has once again lost business to SpaceX because its Starliner capsule is not yet ready. In the long run this contract means fewer total flights for Boeing to ISS, which means less profits.
NASA announced yesterday that engineers have finally completely restored its Mars orbiter MAVEN, after a three month period when the spacecraft was in safe mode due to an attitude control problem.
To fix the problem engineers uploaded new software that allowed the spacecraft to determine its orientation in space not from its onboard inertial units, but from locking onto stars in the sky.
All instruments were healthy and successfully resumed observations; however, the spacecraft was constrained to pointing at the Earth until testing of all-stellar mode was completed, so the instruments were not oriented as they normally would be during science operations. Nevertheless, some limited science was still possible, and MAVEN even observed a coronal mass ejection impact Mars less than two days after the instruments were powered on.
Moreover, for some parts of the year it will still need its inertial units, so a fix for those time periods is still required.
Regardless, MAVEN can now resume acting as a communications relay between the Earth and the rovers on Mars, which for the past year has become its prime mission. While both rovers can communication without that relay, it is often necessary depending on a number of factors, and it also provides redundancy and a greater communications capacity.
Capitalism in space: The new rocket engine company Ursa Major yesterday announced a new more powerful rocket engine, dubbed Arroway, designed to replace rocket engines that Russia had been selling.
Arroway is a 200,000-pound thrust liquid oxygen and methane staged combustion engine that will serve markets including current U.S. national security missions, commercial satellite launches, orbital space stations, and future missions not yet conceived. The reusable Arroway engine is available for order now, slated for initial hot-fire testing in 2023, and delivery in 2025.
Notably, Arroway engines will be one of very few commercially available engines that, when clustered together, can displace the Russian-made RD-180 and RD-181, which are no longer available to U.S. launch companies.
Arroway could replace the RD-181 engines that Northrop Grumman uses on the first stage of its Antares rocket. Both engines are comparable in size. However, with Arroway available no sooner than ’25 it still will leave a gap, since right now the company only has enough stock on hand to launch two more rockets, both of which should launch before ’24.
Arroway is also about half as powerful as Blue Origin’s BE-4 engine, so if ULA wishes to use it in its Vulcan rocket a major redesign would be required.
Either way, Ursa Major is demonstrating here again the value of freedom and competition, as well as the foolishness and negative consequences of Russia’s invasion of the Ukraine. In response to the international sanctions against it, Russia blocked future rocket engine sales to the U.S. Not only did that not get the sanctions lifted, Russia is now losing that U.S. business, as other American companies are stepping up to replace it.
