New Arianespace Vega-C rocket being prepared for first launch in April

9:22 am

Engineers in French Guiana are now preparing all the components of the first Vega-C rocket, built by the Italian company Avio, for its first launch in April.

Vega-C is an upgraded version of the Vega rocket and is currently set to launch no earlier than April 2022. The rocket will feature improved first and second stage solid rocket motors, an upgraded liquid-fueled AVUM+ upper stage, and usher in an era of propulsion system commonality between the Vega and Ariane rocket lines.

At the moment they are modifying the Vega launchpad and building a new mission control center. Once completed in March they will stack the rocket.

Vega-C, like its predecessor, is powered by solid rockets, which Avio believes can be competitive with reusable rockets, at least for the next decade or so. Arianespace also hopes to lower costs by using the exact same solid rocket boosters on both Vega-C and its new Ariane 6 rocket. Vega-C’s first stage, using a P120C solid rocket motor, is also used as side boosters on Ariane 6.

China tests space junk removal robot in geosynchronous orbit

9:08 am

China has apparently used a space junk removal robot to tug a defunct Chinese satellite out of geosynchronous orbit, thus opening that slot for future satellites.

Ground tracking by ExoAnalytic Solutions found that the robot, dubbed SJ-21, apparently docked with the defunct satellite on January 22nd. Since then:

In an email to Breaking Defense this afternoon, Flewelling [of ExoAnalytic] said the latest tracking data gathered earlier today from ExoAnalytic’s telescopes show the SJ-21 separating from the Compass G2, leaving the latter in the eccentric “super-graveyard drift orbit.” SJ-21 now has moved back to a near-GEO orbit.

The orbit places the defunct satellite in an orbit above the geosynchronous orbit satellites use, but in an orbit that is not typical.

This work is comparable to what the Japanese/American company Astroscale is presently testing in low Earth orbit, though it appears far more sophisticated. In fact, based on what SJ-21 has done so far, it appears China is far ahead of everyone else in developing in-orbit robotic servicing capabilities.

Astroscale stops orbital capture demo after detecting “anomalous spacecraft conditions”

5:22 pm

Capitalism in space: Astroscale has halted an ambitious demonstration in-orbit of its magnetic capture technology when its engineers detected “anomalous spacecraft conditions.”

The demo involved a client satellite (posing as space junk) and a separate robot. Both were equipped with Astroscale’s magnetic capture device. A test in August had successfully separated the two units by a small distance, and then demonstrated that the magnetic capture device could grab the client satellite.

In the on-going but paused demo the robot was to separate, fly a distance away, and then use its autonomous programming to rendezvous with the client and then recapture it again. It successfully separated but that’s when the anomalies were detected. Engineers are now reviewing the data to see if they correct these issues and then proceed with the rest of the demo.

If successful Astroscale would demonstrate that their magnetic capture system works, thus giving them a strong selling point to have satellite companies buy it and install it on their satellites. Then, when the satellite was no longer needed Astroscale could send a robot up, capture it, and then de-orbit it safely.

Oman signs deal with companies to build and launch its first probe beyond Earth orbit

1:33 pm

Capitalism in space: The Sultanate of Oman has finalized an agreement to have the Polish company SatRevolution build its first probe to go beyond Earth orbit and have Virgin Orbit launch it.

The target beyond Earth and the missions specific goals has not yet been determined, though the goal is to launch it before the end of ’24.

This agreement is in a addition to an earlier agreement by the same entities to build and launch Oman’s first satellite, set to launch from an airport runway in Cornwall, Great Britain, sometime later this year.

What this agreement tells us that there is money to be made building spacecraft and launching them. Oman wants to have its own space program, like its neighbor the United Arab Emirates (UAE), but like the UAE it does not have the aerospace industry to make that possible. The solution? Hire the skillsets of private companies, in this case from the U.S. and Poland.

Stratolaunch wins Air Force hypersonic research contract

1:17 pm

Capitalism in space: Stratolaunch today announced [pdf] that is has been awarded by the Air Force contract to study whether its Roc aircraft carrier and Talon-A research craft will be useful in test hypersonic weapons and spacecraft.

Stratolaunch, LLC is pleased to announce a research contract with the U.S. Air Force Research Laboratory (AFRL).

Stratolaunch, under partnership with Booz Allen Hamilton, is on contract with AFRL to examine and assess the feasibility of hypersonic flight tests of a wide range of Air Force experiments and payloads on a frequent and routine basis.

Stratolaunch supports national security objectives for hypersonic offensive and defensive weapons development through the design, manufacture, and operation of a fleet of reusable hypersonic aerospace vehicles air-launched from its globally deployable carrier aircraft, Roc. The company plans to augment existing Department of Defense flight test resources through affordable, commercially contracted, rapid-turnaround hypersonic flight testing for the Department of Defense and its prime contractor partners.

This contract is not to do actual tests, but to study whether Stratolaunch’s equipment can make hypersonic tests easier, cheaper, and more frequent, as the company promises.

Eta Carinae: The star that proved Hubble was fixed

1:02 pm

The Space Telescope Science Institute, which operates both the Hubble Space Telescope and the James Webb Space Telescope, today released a wonderful short video summarizing in images the decades of knowledge that Hubble has gleaned of the massive star Eta Carinae.

I have embedded that video below the fold. What makes Eta Carinae special is that when Hubble was pointed at it shortly after the first repair mission in 1993, that photo proved without a doubt that the telescope’s vision had been fixed. More important, the photo proved that Hubble was going to routinely show us things never before seen. In this case, we got our first sharp and unambiguous view of a massive star exploding.

Today’s blacklisted American: Minnesota Bank & Trust closes all accounts of Mike Lindell of My Pillow, because he has opinions

11:42 am

Mike Lindell and My Pillow, cancelled
Mike Lindell and My Pillow, cancelled

The new dark age of silencing: Because Mike Lindell, owner of My Pillow, is very vocal and active in promoting his pro-Trump and conservative beliefs, his bank has suddenly decided he must be blackballed, and is demanding he close all his accounts with it.

The bank, Minnesota Bank & Trust and Heartland Financial, explained in a phone conversation with Lindell that they were doing this out of fear.

The [controller for Lindell’s companies] asked in the call why the bank, a subsidiary of Heartland Financial, is associated with “someone who could be in the news.”

“Not that the FBI is even sniffing and looking, but what if somebody came and said, ‘Do you know what? We are going to subpoena all of his account records, and this and that. And then all of a sudden we make the news,” the [bank] executive said.

“So it’s more of a reputation risk,” he said.

FTC moves to block Lockheed Martin’s acquisition of Aerojet Rocketdyne

9:18 am

The Federal Trade Commission has sued to block Lockheed Martin’s purchase for $4.4 billion the rocket engine company Aerojet Rocketdyne.

The FTC apparently believes that the acquisition would give Lockheed Martin an unfair competitive advantage. It could refuse to sell Aerojet’s engines to the competitors who depend on them. It also would be able to obtain some of its competitors’ proprietary information through Aerojet.

This quote from the article however explains this action more accurately:

Over the past year, Lockheed Martin has argued that the merger should follow the same template as Northrop Grumman’s acquisition in 2018 of solid rocket motors manufacturer Orbital ATK. The Northrop-Orbital deal was approved by regulators on condition that the company agreed to supply motors to its competitors.

“The FTC during the Biden administration has taken a different view on market concentration and vertical integration than the last one, which approved the Northrop Grumman-Orbital ATK deal,” noted industry analyst Byron Callan, of Capital Alpha Partners. [emphasis mine]

This appears to be more evidence that Democratic Party control of the White House is resulting in more regulation and greater interference in the private sector. In this particular case that interference might very well cause Aerojet Rocketdyne to shut down entirely, since its customer base has been disappearing. It isn’t garnering any new customers because its rocket engines cost too much. Folded into Lockheed Martin the company might be reshaped and become productive and competitive again. Unfortunately, the Biden administration thinks it knows better, and might prevent that from happening.

Isar Aerospace wins $11.3 million in EU innovation competition

9:05 am

Capitalism in space: The German rocket startup company Isar Aerospace has won the first place $11.3 million prize in the European Innovation Council Horizon Prize in the category of low-cost rockets.

Isar was one of three finalists for the prize announced earlier this month by the European Commission, along with another German small launch vehicle developer, Rocket Factory Augsburg, and Spanish company Payload Aerospace, which is working on a reusable small launcher. Those three came from an initial pool or more than 15 applicants, Breton said at a ceremony during the conference to announce the winner.

Isar hopes to launch its rocket, called Spectrum, late this year.

Whether this contest marks the beginning of an open and competitive launch industry in Europe remains unclear. Apparently the EU is thinking of creating what it calls the “European Space Launcher Alliance,” which — from the vague descriptions of it as well as the reservations expressed by Isar officials — might force independent companies to cater their actions to the needs of the larger rocket companies, like Airbus and ArianeGroup. This quote suggests the thinking of those larger companies:

“We understand how important it is for Europe to grab and keep leadership,” said Morena Bernardini, vice president of strategy at ArianeGroup. “This is possible only if industry is pushing in one direction.” [emphasis mine]

If I was a new startup, the highlighted words from this powerful established big space company would worry me enormously. Who decides what that “one direction” is? And what if different companies want to approach rocketry differently?

Lucy update: cause of solar array issue identified

8:49 am

Lucy solar panel graphic

According to the principal scientist for the Lucy asteroid mission, engineers think they have identified what caused one of Lucy’s two fanlike solar arrays to fail to deploy completely.

The +Y array, rather than unfurling a full 360 degrees, instead went 347 degrees. In that configuration, the spacecraft is still generating more than 90% of its expected power. “Power is not an issue for the spacecraft, nor will it be through the entire mission if we have to fly it like it is.”

The arrays unfurl when a motor pulls on a lanyard, swinging one end of the array around and into place. Levison said that the most likely reason the array did not latch is that, for some reason, there was a loss of tension in the lanyard during deployment. That caused it to fall off a spool and wrap around the motor shaft. About 75 centimeters of lanyard remains to be pulled in.

It appears they in April will turn on the array’s motor to try to pull the lanyard in that last little bit. If that doesn’t work, they will then simply leave things as they are, as it appears the array is open enough to give them sufficient power for their mission.

There are risks to that course, however. Because the array is not latched open, it could begin to close, and thus result in less power to the spacecraft. Furthermore, its unlatched state appears to make some planned engine burns too risky.
