UK Space Agency proudly grows

9:27 am

The United Kingdom Space Agency today announced that it is opening four new offices in four different cities, giving it a brand new headquarters as well as a total of five regional offices.

The new HQ at Harwell is due to open in June, while offices at William Morgan House in Cardiff and Space Park Leicester will open in April, with the office at Queen Elizabeth House, in Edinburgh, opening later in the summer.

In addition, the agency will retain its offices in London and Swindon.

Will this expansion alleviate the serious red-tape issues in the United Kingdom that killed Virgin Orbit and have delayed launches at its two new spaceports in Scotland? I have my doubts. The licensing problems in the UK have centered on the number of different agencies and offices that must issue approvals to private space companies. While it might make sense for the UK Space Agency to hire more people, if anything it should be streamlining its operations to one central place.

It appears instead that this bureaucracy is doing what all government bureaucracies do, expanding and growing at the cost of private enterprise. I don’t see how opening many different small offices can possibly help make the licensing procedure faster or easier.

Antenna for joint NASA-ISRO radar satellite needs fix, delaying launch

8:50 am

The large deployable antenna for a joint NASA-ISRO radar satellite, dubbed NISAR, that was targeting a spring launch will require an extra coat of reflective material, thus delaying the satellite’s launch until the second half of this year.

In a March 22 statement, NASA said a new launch date for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission will be set at the end of April because of work to protect the spacecraft’s reflector, an antenna that is 12 meters across when fully deployed, from temperatures when in its stowed configuration. “Testing and analysis identified a potential for the reflector to experience higher-than-previously-anticipated temperatures in its stowed configuration in flight,” NASA said in the statement. To prevent those increased temperatures, a “special coating” will be applied to the antenna so that it reflects more sunlight.

That work, NASA said, requires shipping the antenna, currently with the rest of the NISAR spacecraft in India, to a facility in California that can apply the coating. NASA did not state how long the process of applying the coating, as well as shipping the antenna to California and then back to India, will take.

It appears that the need for this additional coat was discovered during environmental testing by ISRO engineers in India as part of its preparation for launch on India’s GSLV rocket. Based on the JPL website for this mission, it appears this antenna system was built by JPL.

NASA is providing the mission’s L-band synthetic aperture radar, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder and payload data subsystem. ISRO is providing the spacecraft bus, the S-band radar, the launch vehicle and associated launch services.

Though the purpose of the final environmental testing prior to launch is specifically to find such issues and correct them, the question remains why this issue occurred. One can’t help wondering if the many management problems detailed at JPL in several reports (here, herej, here) might have contributed, including the organization’s total commitment since 2022 to Diversity, Equity, and Inclusion quotas, making skin color and sex the primary qualifications for hiring, rather than skill, education, or talent.

SpaceX launches more Starlink satellites

9:17 am

The beat never ends: SpaceX last night successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage successfully completed its nineteenth flight, landing successfully on a drone ship in the Atlantic. This stage is now the third that has completed a record nineteen flights. One wonders when a stage will reach twenty.

The leaders in the 2024 launch race:

29 SpaceX
12 China
4 Rocket Lab
4 Russia

American private enterprise now leads the rest of the world combined in successful launches 34 to 22, while SpaceX now leads the entire world, including American companies, 29 to 27.

Russians launch three astronauts to ISS

2:20 pm

The Russians today successfully launched three astronauts to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The Soyuz is scheduled to dock with ISS on March 25, 2024. The Russian and Belarus astronauts will stay on board ISS for about two weeks, returning to Earth on an Soyuz-2 capsule that is presently docked to ISS, taking with them an American who has just completed six months in space. The American on today’s launch will now start her own six month mission, and will return in September with two Russian astronauts who are presently on a year long mission, one of whom will likely set a new duration record for a woman.

The leaders in the 2024 launch race:

28 SpaceX
12 China
4 Rocket Lab
4 Russia

American private enterprise still leads the rest of the world combined in successful launches 33 to 22, while SpaceX remains ahead of the entire world, including American companies, 28 to 27.

Martian vent or sink?

11:37 am

A Martian vent or sink?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on January 29, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Though the scientists label this image showing “channels”, what I see is either a vent or a sink, with the channels to the south indicating past flows either coming out of the depression or into it. The uncertainty exists because the surface grade in this region is essentially flat. There is a lot of small up and down variations, but overall it is very difficult to determine the general trend, suggesting that when the depression and channels formed the grade was different, and there is no way from this data to determine the angle at that time.

Were the flows that created the channels lava or water or ice? Knowing the grade when these channels formed would help answer this question, but other research now suggests the latter.

Australia moves to make skin color and sex more important in hiring space engineers than skill or knowledge

9:18 am

A new industry group, established with full support of the Australian government, has been formed to encourage the hiring of minorities and women in that nation’s space industry, merely because they are minorities and women.

The Australian Space Diversity Alliance (ASDA) said it aims to support senior leaders and minimise the barriers that marginalised groups face. It comes after a series of reports have shown the sector is lagging behind others in regard to gender disparity, and alongside a talent shortage critics say can only be overcome with a more diverse intake.

ASDA was founded by eight industry figures, including Defence Council of Victoria’s Anntonette Dailey, ANU’s Dr Cassandra Steer, and Raytheon’s Linda Spurr. Defence Connect is one of the group’s industry partners, alongside five state governments, the iLAuNCH Trailblazer initiative, and communications agency The Write Space.

It makes the typical and very bogus claims of these Diversity, Equity, and Inclusion (DEI) programs that because woman comprise only 20% of the people in the space industry and minorities only 5%, bigotry must be involved. And the only solution is more bigotry, by favoring applicants from those groups even it they are less qualified than others.

The possibility that women and minorities might simply not be interested in doing this work is a reality that these race hustlers simply can’t tolerate. No, if women and minorities aren’t represented at a level we believe appropriate, we will make it so, regardless of skills, talent, knowledge or experience.

Expect the entire Australian space industry to suffer because of this effort.

ISRO completes second drop test runway landing of its own mini-reusable shuttle

8:56 am

Pushpak about to land
Click for original image

India’s space agency ISRO yesterday successfully completed the second runway landing of its own mini-reusable shuttle, dubbed Pushpak, after the vehicle was dropped from a helicopter at an altitude of 2.8 miles.

This mission successfully simulated the approach and high-speed landing conditions of RLV returning from space. With this second mission, ISRO has re-validated the indigenously developed technologies in the areas of navigation, control systems, landing gear and deceleration systems essential for performing a high-speed autonomous landing of a space-returning vehicle. The winged body and all flight systems used in RLV-LEX-01 were reused in the RLV-LEX-02 mission after due certification/clearances. Hence reuse capability of flight hardware and flight systems is also demonstrated in this mission. Based on the observations from RLV-LEX-01, the airframe structure and landing gear were strengthened to tolerate higher landing loads. [emphasis mine]

The highlighted sentences I think are the most significant. ISRO is pushing hard for reusability.

The concept of this spacecraft is somewhat comparable to the X-37B, though all the engineering can be applied to larger shuttles that can carry cargo and humans in and out of orbit. At the moment however Pushpak is simply an engineering test prototype, not yet ready for orbital flights. For example, the landing gears are too large and cannot be retracted, something unacceptable for orbital flights.

SpaceX launches a cargo Dragon to ISS

2:18 pm

SpaceX today successfully launched a Dragon freighter to ISS, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The cargo Dragon was flying for the fourth time. It will dock with ISS on March 23, 2024. The first stage completed its sixth flight, landing back at one of SpaceX’s landing pads at Cape Canaveral.

This was also the first Dragon launch from this particular SpaceX launchpad in four years. The company only recently reconfigured it for Dragon flights, both manned and unmanned, so that it has two options for launching NASA manned missions. NASA had demanded this before it would give SpaceX permission to launch Superheavy/Starship from that rocket’s new launchpad in Florida. The agency thought it was too close to SpaceX’s first manned launchpad, and wanted an option in case a Superheavy launch failure damaged the Dragon launchsite. With this success SpaceX is one step closer to flying operational Superheavy/Starship flights out of Cape Canaveral.

The leaders in the 2024 launch race:

28 SpaceX
12 China
4 Rocket Lab
3 Russia

American private enterprise now leads the rest of the world combined in successful launches 33 to 21, while SpaceX now leads the entire world, including American companies, 28 to 26.

Some more “What the heck?” geology on Mars

2:00 pm

What the heck?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 1, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a small part of a region dubbed Iani Chaos, but what this geology shows is way beyond my pay grade.

Why there are those tiny aligned mounds, oriented at right angles to the slope, is not clear at all. Nor is it obvious what created the lighter chaotic terrain at the base of the slope.

The elevation difference between the low and high points is about 400 feet. The slope continues up to the west for another 600 feet to the top of a north-south ridgeline. The patterns here suggest vaguely some flows downhill, such as that widening east-to-west gap, but only vaguely.

The look at the overview map only compounds the mystery.

Citizen scientist project discovers 16 active asteroids

10:39 am

A project that has enlisted approximately 8,300 ordinary citizens to review more than 430,000 photos taken by a telescope in Chile has discovered sixteen asteroids that produce comae and tails like comets.

Identifying and tracking active asteroids whose activity specifically appears to be due to the sublimation of ice – known as main-belt comets – is a particular interest of the project team, as it is an essential part of understanding the abundance and distribution of volatile material like ice in the Solar System.

…The project, utilizing publicly available Dark Energy Camera (DECam) data from the Victor M. Blanco telescope in Chile, involved the examination of more than 430,000 images of known minor planets by 8,300 volunteers, where images identified by citizen scientists as being likely to contain active asteroids were then passed on to the science team for confirmation and additional analysis.

You can read the research paper here. If you want to participate, the Active Asteroids project is still on-going, and can be accessed here.

Six launch companies give updates on the status of their rockets

9:03 am

Link here. The event was a panel at a conference where officials from SpaceX, ULA, Mitsubishi, Arianespace, Relativity, and Rocket Lab gave presentations.

Based on what is reported at the link, the Mitsubishi update was the most significant:

Mitsubishi Heavy Industries (MHI) successfully launched its H3 rocket Feb. 16 after the rocket’s inaugural launch failed nearly a year earlier, a setback that Iwao Igarashi, vice president and general manager at MHI, called a “nightmare.” “There were no major problems with the rocket” on its second flight, he said.

We will have to see. Though everything worked as planned on the second flight, the true test on whether Mitsubishi has overcome the issues from the first launch will be the rocket’s third launch, presently scheduled for sometime next year.

A Relativity official said their Terran-R rocket is still targeting a first launch in 2026, while Rocket Lab was hopeful that the first launch of its larger Neutron rocket would occur by the end of this year.

China Long March 2D launches “group of satellites”; Russia scrubs manned Soyuz launch

8:45 am

China today successfully launched what it simply labeled as “a group of satellites”, its Long March 2D rocket lifting off from its Jiuquan spaceport in the northwest of China.

No other useful information was released about the payloads. Nor was there any word as to the crash site of the rocket’s first stage, which uses toxic hypergolic fuels and landed somewhere in China.

Meanwhile in Russia a launch of a Soyuz-2 rocket carrying three astronauts to ISS was aborted at about T-20 seconds for reasons that as yet remain unclear. According to NASA the next launch opportunity is March 23, 2024.

The leaders in the 2024 launch race:

27 SpaceX
12 China
4 Rocket Lab
3 Russia

American private enterprise still leads the rest of the world combined in successful launches 32 to 21, while SpaceX remains ahead of the entire world, including American companies, 27 to 26.
