Launch of two South Korean satellites threatened by Russia’s Ukraine war

10:02 am

According to South Korean officials, the launch later this year of two new home-built satellites on Russian rockets is now unlikely because of the sanctions imposed because of Russia’s invasion of the Ukraine.

South Korea’s CAS500-2 remote sensing satellite is set to launch in the first half of this year on a Russian Soyuz rocket from Russia’s Baikonur Cosmodrome in Kazakhstan. South Korea’s KOMPSAT-6 multipurpose satellite, equipped with synthetic aperture radar (SAR), is due to launch in the second half of the year on a Russian Angara rocket from Plesetsk Cosmodrome in northern Russia.

“For now, nothing has changed to the plan,” Korea Aerospace Research Institute spokesman Roh Hyung-il told SpaceNews. “We are taking a close look at how the situation unfolds because it could have a significant impact on our missions.” He admitted that it’s “very likely” that the satellites won’t be launched as planned.

Those officials also said that losing Russia as a launch option will be a “serious blow” to South Korea’s entire space effort. I find that puzzling. There are plenty of other rocket companies now available. Why South Korea feels a need to depend on Russia seems short-sighted.

Shetland spaceport gets third launch customer

9:52 am

Capitalism in space: The United Kingdom’s Shetland spaceport, SaxaVord, announced today that it has signed a third launch customer, the smallsat rocket startup Venture Orbital Systems.

Venture Orbital Systems (VOS), a developer of micro launchers and rocket engines based in Reims, France, plans to use the site at Unst as part of its aim to reach 15 launches of its Zephyr rocket by 2026 and 40 by 2030.

The new spaceport, presently under construction, already has ABL as a future rocket compan. ABL, mostly owned by Lockheed Martin, hopes to launch before the end of the year.

The UK’s has a second spaceport under construction in Sutherland, Scotland. It will be interesting to see if both can garner enough business to prosper.

Former CEO of Virgin Galactic sued over his pump-and-dump stock sale

9:44 am

Buyer beware: Chamath Palihapitiya, who recently stepped down as CEO of Virgin Galactic, has been sued by some of the company’s stockholders for using his insider position to pump-and-dump his stock while keeping vital information secret illegally.

The complaint, filed on behalf of Virgin Galactic to seek damages from its directors and officers, also alleges that founder Richard Branson pocketed $301 million by dumping his shares while the stock price was “artificially inflated.”

Leaders of the company were well aware of defects in its spacecraft three years before they were publicly disclosed last year, according to the complaint filed in federal court in Brooklyn, New York.

It is unclear from the article whether Branson is being sued as well.

Satellite photos suggest Iran had a launch failure with rocket explosion on launchpad

9:38 am

Based on new satellite photos, it appears that an attempt by Iran to launch a satellite failed this week when the rocket exploded on the launchpad.

Before and after images taken by imagery satellites from two different private companies, Maxar and Planet Labs, suggest the incident likely occurred around February 26th.

Satellite images from Maxar Technologies seen by The Associated Press show scorch marks at a launchpad at Imam Khomeini Spaceport in Iran’s rural Semnan province on Sunday. A rocket stand on the pad appears scorched and damaged, with vehicles surrounding it. An object, possibly part of the gantry, sits near it.

Successful launches typically don’t damage rocket gantries because they are lowered prior to takeoff. Iran also usually immediately trumpets launches that reach space on its state-run television channels, and it has a history of not acknowledging failed attempts.

The news reports claims that the failed rocket was Iran’s Zuljanah rocket, which uses solid rocket motors for its lower stages. Zuljanah has never made orbit, having been unveiled one year ago after a single suborbital test flight.

OneWeb scraps further launches from Russia

9:12 am

OneWeb’s board of directors has voted to cancel all further launches of its satellites from Russia, refusing to meet Russia’s demand that the United Kingdom divest its half share in the company.

On Thursday, OneWeb said the company’s board had voted to suspend all launches from Baikonur, Kazakhstan, where the Russian spaceport operated by Roscosmos is based.

OneWeb didn’t elaborate on the vote. But the UK’s Business and Energy Secretary, Kwasi Kwarteng, said his government had refused to divest from OneWeb, which received funding from British authorities in 2020 to stave off a bankruptcy. “The UK Government supports OneWeb’s decision,” Kwarteng tweeted on Thursday. “In light of Russia’s illegal and unprovoked invasion of Ukraine, we are reviewing our participation in all further projects involving Russian collaboration,” he added.

OneWeb hasn’t commented on the company’s contingency plans. But it’s almost certainly looking for a new launch partner. Russia’s Roscosmos previously helped OneWeb send up 428 of 648 satellites for its internet system, which is designed to serve enterprise users.

This decision, combined with Russia’s decision to suspend further Soyuz-2 rocket launches from French Guiana, essentially ends Russia’s partnership with Arianespace. It also likely ends for many years Russia’s place in the international launch market. OneWeb and Arianespace were its last remaining international customers, and their business is now gone. Even if the Ukraine War was settled today, I suspect neither would wish to renew their business with Russia.

As for OneWeb, it has a number of options in the growing launch market, with Arianespace’s rockets its most likely choice. Financially, the delay hurts them in two ways: First, they have paid Russia for a number of launches already, and Russia has said it will not refund the money. Thus, those launches will cost twice as much. Second, the delay hurts them in their effort to compete with SpaceX’s Starlink constellation.

Martian crater overwhelmed by glacier?

Martian crater overwhelmed by glacier?
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on January 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter. It shows what the science team labels a “modified crater.”

What I see is an old crater almost completely covered by glacial material. That material however is also very old, as there are numerous small craters on its surface, enough that it must have been here for a long time. Its cracked surface also suggests this glacier is very old.

Thus, while we might have ice here, buried by a thin layer of dust and debris to prevent it from sublimating away, it must be very old ice. The many climate cycles caused by the extreme swings in Mars’ rotational tilt, from 11 to 60 degrees, have apparently not caused this ice to ebb and flow very much.

Might it therefore not be ice, but hardened lava?

The location, as shown by the overview map below, provides some context, but only makes this mystery more puzzling.

Sunspot update: The Sun rages on

10:54 am

Time for my monthly sunspot cycle update, where I take NOAA’s monthly graph showing the long term trends in the Sun’s sunspot activity, and annotate it with additional data to provide some context.

The trend of sunspot activity exceeding the predictions continued in February. While the increase in activity from January still left it less than the activity in December, the total number of sunspots is still far above the number predicted by NOAA’s panel of solar scientists in 2020, with the rise towards a solar maximum also much steeper and far faster than predicted.

Romania signs Artemis Accords

9:08 am

Romania on March 1st became the sixteenth nation to sign the Artemis Accords, designed to get around the Outer Space Treaty’s restrictions on private enterprise and property rights in space.

Romania is now the third former Soviet block nation to sign the accords, joining Poland and the Ukraine. The full list of signatories now includes Australia, Brazil, Canada, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Up to now Germany and France — two of the west’s most important major space powers — have resisted signing, probably because both countries have had strong partnership ties with Russia, and Russia opposes the accords. The Russian invasion of the Ukraine however has caused Germany to break off all such Russian cooperation, which suggests it now may be more amendable to signing. I also suspect France may become more willing, though predicting France in these matters is always difficult.

Germany turns off its instrument on the Spektr-RG orbiting X-ray telescope

8:59 am

As part of Germany’s decision to break off all scientific cooperation with Russia in response to Russia’s Ukraine invasion, the Max Plank Institute has turned off its instrument on the Spektr-RG orbiting X-ray telescope.

Meanwhile, Roscosmos’ head, Dmitry Rogozin revealed he will demand compensation from Europe for its sanctions, including this shut down on Spektr-RG.

Europe’s sanctions cause real losses to Russia’s space corporation Roscosmos. The corporation will estimate them and demand a compensation from partners in Europe, Roscosmos’s press-service told TASS on Tuesday. “They have caused harm to the Spektr-RG laboratory’s research program by turning off one of the two telescopes. Their sanctions cause real losses to us. The damage will be estimated and a bill presented to the European side,” Roscosmos said.

It now appears that all the European cooperation with Russia in space is likely dead, at least until Russia gets out of the Ukraine.
