ISRO considering doing more docking tests with Spadex satellites

India’s space agency ISRO has delayed the undocking of its two Spadex satellites as it considers a plan to do more docking tests.

The original plan was to have the chase satellite complete only one docking with the target vehicle, after which the two satellites would separate and spend the next two years doing different work. That plan is being reconsidered.

[Isro chairman V.] Narayanan said in Sriharikota that they have to think of the money involved in such projects and utilise it to the maximum. “Now we are in the process of reviewing when to do the undocking, the power connections and when to totally separate them again and dock again. All these processes are going on. We do not want to undock and leave it,” the Isro chairman said.

“We have loaded five kg of propellant on both the satellites. The propellant is needed for docking and undocking exercises. Currently we have 60 to 70 per cent of the propellant (as of January 29) remaining in the spacecraft. There are going to be a lot of experiments in the docking, undocking, power connection exercises and it is not a one time exercise,” he said.

Sources at ISRO also suggest there may be issues with the docking that still need analysis.

UAE hires Thales-Alenia to build its airlock for Lunar Gateway

The European space company Thales-Alenia today announced that it won the contract from the United Arab Emirates (UAE) to build its airlock for Lunar Gateway.

It was expected, that after the UAE signed its agreement with NASA in early January to build this airlock in exchange for one astronaut flight to Lunar Gateway, that it would also have to hire someone to build it since that country does not have the capability. Initial reports suggested it was negotiating with Boeing to build the airlock, but not surprisingly the UAE ended up going elsewhere, considering Boeing’s present troubles. Either the UAE decided Boeing was too great a risk and too expensive, or Boeing’s new upper management decided to beg off.

As noted here, Thales Alenia now has contracts to build four major components of Lunar Gateway: the hull of NASA’s habitation module, Europe’s habitation module, the refueling/telecommunications module, and now the airlock. While the graphic below shows that other Gateway components are being built by others, the graphic also shows that NASA has past off many modules to other countries. These deals could make it easier politically for the Trump administration to cancel Lunar Gateway. Thales-Alenia’s dominant position in building the station in Europe would make transferring ownership to Europe simpler, with U.S. participation secondary. The European Space Agency for example could pick up the cost for the modules being built by SpaceX and others.

SpaceX launches two high resolution Earth imaging reconnaissance satellites

SpaceX tonight successfully launched Maxar’s last two of six high resolution Earth imaging reconnaissance satellites of its Worldview constellation, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

SpaceX placed the entire Worldview constellation in orbit over three launches. The first stage on today’s launch completed its fourth flight, landing back at Cape Canaveral, while the rocket’s two fairing halves completed their 21st and 23rd flights respectively.

This was also SpaceX’s second launch today.

The 2025 launch race:

16 SpaceX
6 China
1 Blue Origin
1 India
1 Japan

Gullies on crater wall

Gullies on Mars
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 8, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture’s research focus is the gullies, which the scientists’ describe as “perched pole-facing gullies on ancient crater wall.” Perched means the start and end of each gully is on that crater wall, linked neither to the top or bottom of the wall itself. That the gully starts below the top means whatever caused it came from within the wall itself, not from the plateau above. That it ends before the crater floor means the process that cut the gully out was not powerful enough to reach the bottom.

That the gullies are on the interior north wall of this unnamed 25-mile-wide crater means they get less sunlight year round, something that must play a part in causing the gullies.

Astronomers find galaxy with nine rings

The Bullseye Galaxy
Click for original image.

Using both the Hubble Space Telescope as well as the Keck telescope in Hawaii, astronomers have discovered a galaxy with nine rings, something never seen before.

The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings.

More information from Keck can be found here.

Keck Observatory and Hubble’s follow-up observations helped the researchers prove which galaxy plunged through the center of the Bullseye — a blue dwarf galaxy to its center-left. This relatively tiny interloper traveled like a dart through the core of the Bullseye about 50 million years ago, leaving rings in its wake like ripples in a pond. A thin trail of gas now links the pair, though they are currently separated by 130,000 light-years.

The Hubble picture is to the right, cropped, reduced, and sharpened to post here. The small blue dwarf galaxy to the left is believed to be the galaxy that plowed through LEDA 1313424 to create the rings. LEDA is itself thought to be two and a half times the size of the Milky Way, making one of the larger known galaxies.

NASA calls for the private sector to launch VIPER to the Moon

As a follow-up of its August request for suggestions on how to save its cancelled VIPER rover mission to the Moon, NASA has now issued a request for actual proposals from the private sector for flying the mission, due on March 3, 2025.

The Announcement for Partnership Proposal contains proposal instructions and evaluation criteria for a new Lunar Volatiles Science Partnership. Responses are due Monday, March 3. After evaluating submissions, any selections by the agency will require respondents to submit a second, more detailed, proposal. NASA is expected to make a decision on the VIPER mission this summer.

…As part of an agreement, NASA would contribute the existing VIPER rover as-is. Potential partners would need to arrange for the integration and successful landing of the rover on the Moon, conduct a science/exploration campaign, and disseminate VIPER-generated science data. The partner may not disassemble the rover and use its instruments or parts separately from the VIPER mission. NASA’s selection approach will favor proposals that enable data from the mission’s science instruments to be shared openly with anyone who wishes to use it.

Expect a number of companies to tout their proposals in press releases in the coming weeks.

NASA suspends numerous advisory committees to comply with Trump executive orders

In what appears to be an over-reaction by NASA, it has ordered that numerous science advisory committees suspend all meetings and work so that it make sure they are complying with Trump’s executive orders requiring the removal of all Diversity, Equity, and Inclusion programs.

More here and here.

The orders listed twenty different working groups as well as the cancellation of the first in-person meeting of the Mercury working group this week.

In reviewing the released list of these groups, only two, the EDIA Working Group (Equity, Diversity, Inclusion, and Accessibility) and the H2O program (Here to Observe), are expressly focused on promoting these racist policies. EDIA’s job is to make sure DEI is implemented across all working groups and science projects. H2O is an educational program restricted to “under-represented students” only, which really means minorities only. All other kids need not apply.

All the other research groups are focused on research and science, not DEI. While a review of their work to make sure they don’t have racial quotas might make sense, it seems NASA’s memos shutting them down entirely during that review appears to be overkill, and might actually be an example of malicious compliance, a tactic used by the bureaucracy to generate bad press against a politician’s policy orders. By over reacting the bureaucrats try to make the elected official’s new policy look stupid.

For example, the cancellation of the first in-person meeting of the Mercury exploration working group (MExAG) seems absurd. It was scheduled to occur this week in Maryland to discuss for example the Japanese/Italian BepiColombo mission, and the sudden cancellation resulted in quotes like this:

“We are forced, therefore, to cancel MExAG 2025,” the Mercury committee’s chair Carolyn Ernst, a planetary scientist with Johns Hopkins University Applied Physics Laboratory, wrote in a memo obtained by Space.com. “This turn of events is shocking and concerning, and is extra painful given the order comes four days before our first in-person meeting.” Some committee members had already begun travel for the meeting, Ernst added.

The nearly three-day hybrid meeting was expected to include at up 200 scientists attending either in person of virtually, one scientist Ed Rivera-Valentin shared on the social media site Bluesky. It was expected to include a number of researchers connected to the BepiColombo Mercury mission run by the Japan Aerospace Exploration Agency and the European Space Agency. The probe just made its sixth flyby of Mercury on Jan. 8.

I can see no logical reason for NASA’s management to cancel this meeting other than to create bad press for Trump.

There one other possibility. NASA’s management might simply be running scared, and has decided it must over-react in order to make sure it doesn’t get fired for appearing defiant.

I must add that the suspension of the Earth science working groups is not related to DEI, but to adhere to the Trump executive orders requiring a review of the government’s global warming and climate research. For that order a larger suspension of work makes more sense.

Boeing writes off another half billion dollars due to Starliner

In filing an annual report to the SEC, Boeing revealed that has written off another half billion dollars due to Starliner delays and technical problems, bringing the total the company has lost on the capsule to more than two billion.

In the company’s 10-K annual filing with the U.S. Securities and Exchange Commission Feb. 3, Boeing said it took $523 million in charges on Starliner in 2024. The company blamed the losses on “schedule delays and higher testing and certification costs as well as higher costs for post certification missions.”

Both Boeing and NASA remain utterly silent on the future of Starliner. It remains uncertified for operational manned flights, which means Boeing continues to earn nothing from it. Will it have to fly another manned mission on its own dime to get that certification? Or will NASA instead pay it to fly a cargo mission to ISS, as rumors have suggested, to prove the capsule is ready for manned flights?

No one knows. Nor do we know if Boeing will either sell off its space division or cancel Starliner entirely and thus free itself of the problem.
