COVID-19 and launchpad issues delay Ariane 6

10:00 am

The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.

“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.

ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.

It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.

Launch failure for China’s new Kuaizhou-11 rocket

9:49 am

For reasons not yet specified, China’s new Kuaizhou-11 rocket today failed on its inaugural launch.

Many reports will say that this is a commercial rocket developed by the private company Exspace. That is not true. Like all Chinese aerospace companies, they do their work wholly under the supervision of the Chinese government.

The development of the KZ-11 began in 2015, with a maiden launch originally scheduled for 2018. The rocket is developed by China Aerospace Science and Technology Corporation (CASIC) and commercialized by the China Space Sanjiang Group Corporation (Expace).

The launch vehicle can loft a 1,500 kg payload into a Low Earth Orbit (LEO) or 1,00 kg to a 700 km sun-synchronous orbit.

The KZ-11 solid launch vehicle adopts a mobile launch platform, integrated power supply equipment, test and launch control facilities, aiming facility and temperature control facility, to carry vehicles from the technical support center to launch site, complete temperature control of payload, vehicle test and launch.

CASIC is in many ways China’s equivalent of NASA. And everything described in the last paragraph above, from solid rockets to mobile launches, are technologies developed expressly for military purposes. China will not let such things out for commercial companies to use however they wish, no matter what they claim.

Falcon 9 landing leg falls during retraction

10:15 am

Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.

I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.

Solar Orbiter operational, first images to be released

10:05 am

Engineers have now confirmed that Solar Orbiter, having completed its first close fly-by of the Sun, is working perfectly and is producing images and data better than expected.

They will release to the public the first images on July 16.

“The first images are exceeding our expectations,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. “We can already see hints of very interesting phenomena that we have not been able to observe in detail before. The 10 instruments on board Solar Orbiter work beautifully, and together provide a holistic view of the Sun and the solar wind. This makes us confident that Solar Orbiter will help us answer profound open questions about the Sun.”

No other images of the Sun have been taken from such a close distance. During its first perihelion, the point in the spacecraft’s elliptical orbit closest to the Sun, Solar Orbiter got as close as 77 million kilometres from the star’s surface, about half the distance between the Sun and Earth. The spacecraft will eventually make much closer approaches to the Sun. The spacecraft is now in its cruise phase, gradually adjusting its orbit around the Sun. Once in its science phase, which will commence in late 2021, the spacecraft will get as close as 42 million kilometres from the Sun’s surface, closer than the planet Mercury. The spacecraft’s operators will gradually tilt Solar Orbiter’s orbit to enable the probe to get the first proper view of the Sun’s poles.

A previous spacecraft, Ulysses, flew over the Sun’s poles, but it did it from far away, and was designed not to take images but to study the Sun’s solar wind. Solar Orbiter is getting in close.

Putin gov’t arrests journalist working as advisor to Roscomsos

9:24 am

The Putin government yesterday arrested Ivan Safronov, a former journalist presently an advisor to that country’s space agency Roscosmos, for passing military secrets to the Czech government back in 2017 when he was employed by a daily newspaper.

It seems the press in Russia is highly skeptical of these charges.

Kommersant [the daily newspaper in which he had worked] put out a statement in support of Safronov, hailing him as one of the country’s top journalists and a “true patriot” who was deeply concerned about the state of the military and space industries that he covered. The newspaper described the accusations against him as “absurd.” The paper noted that rights activists, journalists, scientists and corporate officials who faced treason accusations found it difficult to defend themselves because of secrecy surrounding their cases and lack of public access. “As a result, the public has to rely on the narrative offered by special services, whose work has increasingly raised questions,” Kommersant said. “Journalists asking those questions find themselves under blow.”

About 20 journalists, including those who worked with Safronov for years, were detained outside FSB headquarters in Moscow when they picketed to protest his arrest. Some were handed court summons for violating a ban on street gatherings during the coronavirus pandemic, an offense punishable by an administrative fine.

Many former colleagues of Safronov alleged that the authorities may have wanted to take revenge for his reporting that exposed Russian military incidents and opaque arms trade deals.

It also appears that the charges have nothing to do with Safronov’s work at Roscosmos.

NASA completes Starliner review, finds more issues

9:15 am

Capitalism in space: NASA yesterday released the results of its investigation into the issues that prevented Boeing’s manned Starliner capsule from successfully completing its unmanned demo flight to ISS in December, finding an additional 20 issues over the 61 initially identified shortly after the mission.

In closing out the seven-month investigation, NASA officials said Tuesday they have now identified 80 corrective actions, mostly involving software and testing, that must be done before the Starliner capsule launches again. The previous count was 61.

NASA officials also admitted that they had been so focused on making sure SpaceX’s Dragon capsule was going to work that they became lax in reviewing Boeing’s work. Now they not only are going to focus more on Boeing, they actually want to use SpaceX’s approach to software development throughout NASA.

NASA is also borrowing SpaceX’s “robust” approach to software, which involves going back to the designers following testing for feedback, said Kathy Lueders, NASA’s new human spaceflight chief who until a month ago managed commercial crew. She wants to see more of that type of approach across other NASA programs.

Though it seems absurd and incredible that NASA has not been consulting with its designers after testing, it is also not surprising. When it comes to designing and building anything at NASA the management processes there have routinely done a bad job for many years.

As for Starliner, it is expected it will take a few more months to fix these issues, which means the next unmanned test flight is likely still set for sometime in the fall, with the manned mission to follow next spring.

Results from Yutu-2 determine “gel-like” rocks are impact melt

9:04 am

Chinese scientists have now published their analysis of the “gel-like” rocks seen by China’s Yutu-2 lunar rover back in October 2019, and have concluded that they are glasses produced from melt occurring during an impact.

The authors describe the material as a dark greenish and glistening impact melt breccia, measuring 20 inches by 6 inches (52 by 16 centimeters). These features are signs of possible presence of glasses, which are usually sourced from impact melts or from volcanic eruptions.

According to the paper, the breccia — broken fragment of minerals cemented together — was formed by impact-generated welding, cementing and agglutinating of lunar regolith and breccia. The material, they say, resembles lunar impact melt breccia samples returned by NASA’s Apollo missions. In particular, similarities with the Apollo samples designated 15466 and 70019 are noted, a comparison made earlier by lunar scientist Clive Neal at the University of Notre Dame. Sample 70019, collected by astronaut and trained geologist Harrison “Jack” Schmitt, is made of dark, broken fragments of minerals cemented together and black, shiny glass.

The results are not definitive, however. The paper notes that the analysis is limited by the fact that VNIS measurements were taken under bad illumination conditions and other factors.

This conclusion is not surprising, as the rover has been traveling through a region dominated by impact ejecta.

Proposed House NASA budget flat, with some surprising support for Artemis

8:51 am

While the first House proposal for NASA’s 2021 budget has rejected the Trump administration’s request for a total $3 billion increase for the agency to fund Artemis so that it can complete a manned mission to the Moon by 2024, it also provided about 18% of the funds requested for building the manned lunar lander required for that mission.

Back in February, the White House asked for $3.37 billion in fiscal year 2021 to accelerate development of the lander.

Democrats in the House have been skeptical of the 2024 launch date—some see it as political due to the timing of the next presidential election—and so have been slow to fund the lander. In its budget, the House appropriates $1.56 billion for “Exploration Research and Development.” This includes funding for the lander, Lunar Gateway, and other activities related to the Moon’s surface, of which more than $600 million can be used for the lander.

The House also provided a boost of $343 million to SLS.

My guess is that the Democrats in the House are working to keep Artemis going because of the jobs it brings to their districts, but want to slow it down enough so that it cannot succeed while Trump is in office. Thus, the release of some funds for the lunar lander, but not enough to build it, now.

The House proposal also includes a loosening on Congress’s mandate that Europa Clipper must launch on SLS. NASA is now given the option to consider other alternatives if SLS is not avaiable, which means that NASA can now consider using the Falcon Heavy instead.

This proposal must still pass the Republican-controlled Senate, so expect more changes.

InSight’s mole is bouncing again

8:24 am

Plan of action for InSight's mole

The engineering team for InSight’s German-built digging tool, dubbed the mole, yesterday reported that it is once again no longer driving into the ground.

Previously they had been able to make progress by having InSight’s scoop press down on the mole. Once the top of the mole however was below ground, the scoop could no longer provide that support, and at that point the mole began bouncing again with each hammer-stroke, the surrounding Martian dirt unable to provide the friction to hold the mole down.

As shown by the illustration above, they are now going to try using the scoop to fill the hole and then use the scoop to press down on the dirt, with the hope this will provide the structural friction required to hold the mole in place after each hammer stroke. This effort will take time, and will prevent the scoop from doing its other work. They are therefore taking a pause until August before beginning the hole-filling operation.
