Psyche will not launch as scheduled

9:06 am

NASA officials yesterday confirmed that because of software issues its asteroid mission Psyche will not launch as scheduled this year.

Due to the late delivery of the spacecraft’s flight software and testing equipment, NASA does not have sufficient time to complete the testing needed ahead of its remaining launch period this year, which ends on Oct. 11. The mission team needs more time to ensure that the software will function properly in flight.

…As the mission team at NASA’s Jet Propulsion Laboratory in Southern California began testing the system, a compatibility issue was discovered with the software’s testbed simulators. In May, NASA shifted the mission’s targeted launch date from Aug. 1 to no earlier than Sept. 20 to accommodate the work needed. The issue with the testbeds has been identified and corrected; however, there is not enough time to complete a full checkout of the software for a launch this year.

NASA management will conduct a review to understand what caused the problem.

As for when Psyche can next launch and reach the asteroid Psyche, the next launch windows in ’23 and ’24 will not arrive at the asteroid until ’29 or ’30 respectively, a flight time that is about two years longer than what the ’22 launch would have been.

Today’s blacklisted Americans: Lawyers who won NY gun rights case in Supreme Court blackballed by their law firm

1:06 pm

A witch hunt against conservative lawyers
The witch hunt against conservative lawyers accelerates.

Blacklists are back and the Democrats have got ’em: The two lawyers who recently won a major gun rights victory in the Supreme Court this week, invalidating the “may-issue” gun control laws in leftist states that prevented anyone from obtaining a gun license, have been blackballed by their law firm, Kirkland & Ellis, and forced to resign.

Former Solicitor General Paul Clement and Erin Murphy, a regular Supreme Court litigator, resigned from Kirkland & Ellis and announced they were opening their own shop in Washington, D.C. Clement has been a high-profile litigator of conservative causes since he left the administration of President George W. Bush. In 2011, he argued the Defense of Marriage Act on behalf of Republican lawmakers before the Supreme Court.

That case also caused Clement to resign from the firm King & Spalding following pressure from clients to drop the gay marriage case.

Perseverance’s first climb

Perseverance's first climb
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on the Mars rover Perseverance on June 16, 2022, shortly after it began its first climb up from the generally flat floor of Jezero crater and onto the delta that once in the far past flowed through a gap into that crater.

I have rotated the image about 8.5 degrees to make horizontal the crater floor and the distant rim of the crater (barely visible through the atmosphere’s thick winter dust). This shows that the rover was then climbing what appears to be a relative low angle grade, hardly as challenging as the serious grades that Curiosity has been dealing with now for the past two years in the foothills of Mount Sharp. Nonetheless, Perseverance has begun climbing.

To see where the rover is see the overview map from the start of this week. Unfortunately, I have been unable to determine the direction of this photo. It could be looking west, south, or east, based on features inside Jezero Crater. I therefore cannot tell you the distance to the rim, which depending on the direction, could be from five to twenty-five miles away.

NASA now targeting late August launch of SLS

11:35 am

NASA officials today confirmed that they are satisfied with the results from this week’s incomplete dress rehearsal countdown of the SLS rocket, and are targeting a late August launch of SLS.

NASA officials have reviewed the data collected during the test run and decided that a leaky hydrogen valve was not significant enough to force a delay in the launch of Artemis I, an uncrewed mission planning to orbit the moon and return to Earth. It’s the first step toward putting humans back on the moon for the first time since Apollo 17 in 1972.

“The team is now ready to take the next step and prepare for launch,” said NASA’s deputy associate administrator Tom Whitmeyer.

NASA officials said they will roll the massive Space Launch System rocket back to the Vehicle Assembly Building, where the valve’s faulty seal will be replaced. Rollback is slated for Friday July 1, though weather concerns could push that back.

SLS won the five-plus year race with the Webb telescope on which would have the most delays and launch last. Now the race will be between SLS and SpaceX’s Starship/Superheavy. Which will launch first this summer? In a rational world, SLS should win hands down. It has been in development since 2004, while Starship only began design work in 2017.

This is not a rational world, however, and SLS’s long gestation had little to do with designing a rocket and everything to do with politics and a corrupt Congress and an incompetent NASA. The rocket that has come out of this is thus difficult to operate and incredibly cumbersome. Its components have also not been tested thoroughly.

SpaceX meanwhile has been designing and building its heavy-lift rocket with only one goal: the rocket must be efficient to operate.

I predict Starship will reach orbit first, though if it doesn’t it most likely will be because SpaceX finds it needs to do more ground tests and revisions, not because SLS has surged ahead. And regardless, Starship will likely fly many times in the next three years, while SLS will only get off the ground once.

More important, the chances of SLS and Orion working perfectly throughout that that lunar orbit mission seem almost impossible, based on track record during the past eighteen years of both programs. Expect some issues to crop up, first during the launch countdown, forcing several scrubs, and then during the mission itself. None might be mortal, but all will raise questions whether it would be wise to put humans on this rocket and capsule on its next flight, and attempt to take them to the Moon.

NASA halts sale of Apollo 11 Moon dust, claiming ownership

10:37 am

We’re here to help you: The auction of a tiny amount of Moon dust brought back by Apollo 11 and used in a post-flight experiment using German cockroaches has been canceled because NASA claimed ownership of that dust and demanded its return.

“NASA asserts legal ownership of the materials consisting of the Apollo 11 lunar dust experiment … based upon the information and documentation provided in the description of the lot and evidence regarding NASA’s contemporaneous contracting practices,” an attorney in NASA’s Office of the General Counsel wrote RR Auction in a letter on Wednesday, a week after first reaching out to the firm. “It is clear and undeniable that the materials consisting of the experiment are owned by NASA.”

The lot under contention comprises what remains from the late Marion Brooks’ research into the physiological effects of lunar material on Blattellas germanica, or German cockroaches. The insects had been fed moon dust by NASA scientists in the immediate aftermath of the 1969 Apollo 11 lunar landing mission. After no ill-effects were seen while astronauts Neil Armstrong, Buzz Aldrin and Michael Collins were held in quarantine, the (now dead) cockroaches were handed off to Brooks, an entomologist from the University of St. Paul, for more thorough study.

Included in the auction was a small vial of moon dust that Brooks’ had carefully extracted from the cockroaches’ corpses, as well as three of the remaining (dead) cockroaches and two boxes of tissue slides for microscopic study.

It appears the dust had been in the Brooks family possession for more than forty years, then sold by them at auction in 2010 for $10,000. Under standard adverse possession law, you lose ownership if you don’t claim that right after twenty years. It would thus seem that NASA’s claim is bogus.

But then, NASA as a government agency doesn’t believe the standard laws apply to it. It continues to demand that all Apollo lunar material belongs to it and be returned, no matter what the circumstances it was originally handed out by the agency and no matter how long ago.

LRO scientists locate impact on Moon from rocket stage believed to be Chinese

10:26 am

Impact, before and after

The science team for Lunar Reconnaissance Orbiter (LRO) today released images identifying the location on the Moon where a mystery rocket stage crashed in March 2022.

The image to the right shows the before and after LRO images, with the impact at the center of the second photo, showing as two superimposed craters. Since the sunlight in the second image come from the opposition direction as the first, the shadows in all previously existing craters are reversed.

Surprisingly the crater is actually two craters, an eastern crater [59 feet diameter] superimposed on a western crater [52 feet diameter]. The double crater was unexpected and may indicate that the rocket body had large masses at each end. Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank. Since the origin of the rocket body remains uncertain, the double nature of the crater may help to indicate its identity.

No other rocket body impacts on the Moon created double craters. The four Apollo SIV-B craters were somewhat irregular in outline (Apollos 13, 14, 15, 17) and were substantially larger [>115 feet in diameter] than each of the double craters. The maximum width [95 feet] of the double crater of the mystery rocket body was near that of the S-IVBs.

Though the evidence strongly points to this stage being from China, that fact is not certain, and China denies that conclusion.

Regardless, the unexpected double nature of the impact only increases the mystery, as it suggests that rocket stage had a mass distribution different than past stages.

NASA blocks Starship/Superheavy launches at SpaceX’s new Florida launchpad

9:37 am

Capitalism in space: NASA officials revealed yesterday that it will not allow any Starship/Superheavy launches at SpaceX’s new Florida launchpad, at least for the moment, because of the threat a launchpad failure might have on the launchpad SpaceX uses to launch manned Falcon 9 missions to ISS.

The NASA statement said the agency “is responsible for ensuring SpaceX remains compliant with the requirements of the property agreement for the use of Launch Complex 39A.”

“These requirements include those related to construction, safety and environmental conditions,” the statement said. “At this time, NASA has only provided approval to build. Additional review for hazards, operational impacts and supportability will be required prior to a launch.”

The new Starship launchpad is 1,000 feet away from pad 39A, which is SpaceX’s manned Dragon launchpad. NASA management thinks this is too close. However, the managers have also not ruled out future launches, only that they wish to do a thorough review of the issue with SpaceX.

Because NASA and the federal government is also relying on Starship to land its astronauts on the Moon, it can’t block Starship flights outright. It could be however that this issue might shift Starship operations back to Boca Chica, after federal government opposition there forced SpaceX to shift more operations to Florida.

In other words, the government wants its cake and eat it to. Some factions within the Biden administration and the Washington bureaucracy want to block Starship, others want it to fly. The result is a tug-of war, with SpaceX in the middle.

OneWeb to resume satellite launches this year, complete constellation by mid-2023

9:24 am

Capitalism in space: According to one OneWeb official at a conference yesterday, the company now expects to resume launching its satellites on SpaceX and Indian rockets by the fourth quarter of this year and will complete its constellation by the second quarter of next year.

Launches were suspended when Russia refused to do a launch — and confiscated the 36 satellites — after Europe imposed sanctions in response to the Russian invasion of the Ukraine.

Speaking at the Fourth Summit for Space Sustainability by the Secure World Foundation and the U.K. Space Agency, Maurizio Vanotti, vice president of space infrastructure development and partnerships at OneWeb, said new launch agreements with SpaceX and NewSpace India Ltd. (NSIL) would allow the company to launch the remaining satellites of its first-generation system by the second quarter of 2023.

“Our plan is to be back on the launch pad in quarter four, after the summer, and to complete deployment of the constellation by quarter two next year,” he said. It will take several months after that final launch for the satellites to move to their operational orbits, he added. “We’re going to be in service with global coverage, 24/7, by the end of next year,” he said.

At present OneWeb has not revealed the breakdown of launches from the two companies.

Blue Origin’s BE-4 engine set for “commissioning” tests

1:29 pm

Capitalism in space: According to a tweet from Blue Origin on June 21, 2022, engineers have finally installed a flight-worthy engine on the test stand in Huntsville for static fire “commissioning” tests.

This is an engine that was supposed to be delivered to ULA for its new Vulcan rocket more than two years ago. With final engine tests only beginning now, it likely means the engine will not be delivered for at least several more months.

ULA will then have to install it in the rocket, and do its own fueling and static fire tests. All this suggests that a Vulcan launch before the end of this year is almost impossible.

When Blue Origin’s own New Glenn rocket will fly using the BE-4 is utterly unknown. ULA at least has built a full-scale test version of Vulcan and done launch countdown rehearsals in order to iron out issues with its launchpad and ground systems. Blue Origin has done none of this.
