LeoLabs to establish radar facility in Argentina

9:41 am

LeoLabs, a private commercial company aiming to provide orbital tracking of all space objects as small as two centimeters, has announced plans to establish its seventh global radar facility in Argentina.

The S-band radar, scheduled to be completed by the end of the year, will be located on the archipelago of Tierra del Fuego. “The Southern Hemisphere has not been well covered for space safety and space domain awareness,” LeoLabs CEO Dan Ceperley told SpaceNews. “There are a lot of conjunctions close to the North Pole and the South Pole. This radar will make a very meaningful improvement in the tracking of those conjunctions.”

Currently, LeoLabs tracks objects in low-Earth orbit with phased array radars in Alaska, Australia, Portugal’s Azores archipelago, New Zealand, Texas and Costa Rica.

The company essentially competes with the Space Force in tracking object in orbit, and has raised more than $100 million in private investment capital to build its ground stations.

Space startups get their SVB assets back when Feds move in

9:34 am

Because of the decision of the federal government to guarantee all deposits at the failed Silcon Valley Bank (SVB), even those above the $250K limit set by the FDIC law, several space rocket startups are no longer threatened with failure, for now.

Astra for example is now seeking to move as quickly as it can its assets, equaling about 15% of the company, to other financial institutions.

I would expect this incident will cause every company to make sure their assets are distributed more widely, as a hedge against the failure of one bank.

An evening pause: Keith Donald is on the sax. Breschi, on the piano, has written other magnificent music. If you can find a copy of his “Language of the Land,” get it. I had posted it as an evening pause, but that video is no longer available on youtube.

Splats on Mars!

Splats on Mars
Click for original image.

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on February 3, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a number of crater splats of varying sizes. If you look at the full image, you will find several even bigger splats to the north of the one in the picture to the right. You will also see many more similar-sized crater splats to the south.

I cannot provide any confident explanation about what caused these splats, other than to assume that most here are secondary impacts from ejecta thrown out by a larger impact somewhere nearby. I also assume all these small impacts occurred at the same time because they all appear to have hit the ground when it had the same thick liquid consistency, a condition that was probably temporary. Note for example how many of the other craters in the full image do not have this same splattered look.

The sad state of free speech in America illustrated by three top universities

1:03 pm

Cancelling the Bill of Rights

Events in the last two weeks at three of America’s top universities, Stanford, Cornell, and Yale, have illustrated starkly how many young Americans and their teachers now either support censorship and violence against dissenters, or are too cowardly to defend the rights of Americans when their free speech rights are attacked.

At the Stanford Law School a 5th Circuit Judge, Stuart Kyle Duncan, was shouted down and then lectured by a dean at the school for daring to have opinions she disagreed with. Stanford officials have issued a weak apology, but have done nothing concrete to discipline anyone for enforcing a heckler’s veto at the school.

At Cornell, the promise of university officials to punish students who participated in a protest that shouted down Ann Coulter has apparently been put aside once the heat died down.

Cornell University’s media team has not responded to multiple inquiries in the past months on possible punishments for the student activists. The College Fix also emailed communications director Rebecca Valli on March 6 and asked for an update on investigations into the students involved and what Cornell planned to do in the future to prevent similar problems.

The silence comes despite an initial strong statement from university leadership that criticized the Nov. 9 disruption.

Finally, officials at Yale Law School have attempted to fix things after being badly embarrassed by a similar violent protest in March 2022, when students shouted down Kristen Waggoner, the president of the non-profit law firm the Alliance Defending Freedom (ADF). » Read more

Chinese pseudo-commercial rocket industry gearing up to launch numerous times from interior spaceport

12:07 pm

China's spaceports

Even as China is presently building a commercial launch facility at its Wenchang spaceport on the coast, at least four of China’s pseudo-commercial rocket companies are gearing up to launch numerous times from the Jiuquan Satellite Launch Center in the interior of China.

The link above shows the launch sites being built at Jiuquan by pseudo-companies Landspace, Expace, CAS Space, and Space Pioneer. The map to the right illustrates what these interior launches will mean. Since none of these pseudo-companies will be vertically landing their first stages — at least not for several years — it means that numerous first stages will be coming down in many areas in China and Mongolia, most of which will be uncontrolled descents.

Eventually the Wenchang launch facility on the coast will become available, but based on past Chinese actions, do not expect these pseudo-companies to end their operations at Jiuquan at that time. All are controlled by the Chinese government, which has made it very clear it really doesn’t care if first stages crash near habitable areas.

Hubble looks at a nearby dwarf galaxy

9:38 am

A nearby dwarf galaxy
Click for original image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a continuing project to capture high resolution images of every nearby galaxy, which in this particular case the caption describes as follows:

UGCA 307 hangs against an irregular backdrop of distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The small galaxy consists of a diffuse band of stars containing red bubbles of gas that mark regions of recent star formation, and lies roughly 26 million light-years from Earth in the constellation Corvus. Appearing as just a small patch of stars, UGCA 307 is a diminutive dwarf galaxy without a defined structure — resembling nothing more than a hazy patch of passing cloud.

The red regions of star formation are significant, as they indicate that even in a tiny galaxy like this it is possible for there to be enough gas and dust to coalesce into new stars.

Astronomers living on a world inside this galaxy have an advantage over astronomers on Earth. There is no large galaxy like the Milky Way blocking their view of the cosmos in one direction. They can see it all, even in directions looking through UGCA 307.

Russia and China launch satellites

9:20 am

Two launches today in Russia and China.

First China used its Long March 2C rocket to launch a “remote sensing satellite” into orbit. No other information about the satellite was released. Nor was any information about whether the rocket’s first stage landed near habitable areas.

Next Russia used its Proton rocket to launch a classified satellite, likely a military surveillance satellite, into orbit. Like China Russia launches from an interior spaceport, with its first stage falling “in Karaganda Region of Kazakhstan,” with the second stage landing in drop zones in Russia. Russia, which has been doing this regularly for more than a half century, has always done a good job either avoiding habitable areas with the first stage crash, or keeping such stories out of the international press.

The 2023 launch race:

16 SpaceX
9 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 9 in the national rankings, and the entire world combined 17 to 15. SpaceX alone is now tied with the entire world, including all other American companies, 16 all.

Curiosity looks ahead: Which way to go?

10:23 pm

Curiosity's view on March 11, 2023
Click for high resolution version. For original images, go here and here.

Overview map

How about a bonus weekend cool image! The panorama above, created from two pictures taken on March 11, 2023 by the right navigation camera on the Mars rover Curiosity, gives us a wonderful view of the alien Martian terrain that the rover is presently within. It also shows us the dilemma mission planners have in planning the rover’s future travels.

The red dotted line on both the panorama and the overview map to the right indicates the planned route. The yellow lines on the map indicates the approximate area viewed by the panorama. The blue dot marks Curiosity’s present position, where it is presently in the middle of a drilling campaign in the marker layer where it sits.

The plan had been to travel to the east of what I like to call the the hill of pillows (in the middle of the panorama). Yet, it appears from this navigation image that the terrain might be less difficult to the west. Both routes will get the rover to its goal in Gediz Vallis.

I have no idea what the mission planners will decide to do. I am just a tourist going along for the ride, and sharing the journey with my readers. This is the first time any human spacecraft has ever traveled through such mountainous terrain on any planet.

Relativity scrubs launch today again

2:06 pm

Relativity today was once again unable to complete the first launch of its Terran-1 prototype rocket.

The failure to launch was not for want of trying. The first countdown was first put on hold at T-1:10 when a boat entered the range. Once removed, the launch team picked up the count from that point without any recycle, but at T-0 the rocket’s internal computer sensed an issue and aborted the launch.

The launch team then reassessed, adjusted that issue, and tried again for a launch at the last second of the launch window, essentially duplicating the circumstances of an instantaneous launch window. The count this time got down to T-45 seconds when once again the rocket’s internal computer sensed an issue and aborted the launch.

No word yet on when the company will try again. If anything, Relativity’s launch team is getting a lot of practice and training with each launch attempt, critical knowledge needed for future launches.

Some space startups threatened by Silicon Valley Bank failure

9:41 am

Link here. The companies mentioned in the article are Astra, BlackSky, Planet, Redwire, Rocket Lab, and Space Perspective.

Rocket Lab has about 8% of its cash assets now trapped by the closure. All the companies had loans from Silicon Valley Bank, some of which were paid off prior to the crash. This quote suggests the situation is critical for some space startups:

“It’s a very serious situation,” said a space sector entrepreneur who asked not to be identified. “Our balance is suddenly only $450. There has been no communication from SVB even after the event became known. Our primary SVB liaison, who has been very attentive in the past, is unreachable by any means. It’s appalling.”
