Rogozin tweets: ISS cooperation to end

5:59 pm

Dmitry Rogozin, the head of Russia’s aerospace corporation, Roscosmos, today confirmed in a series of tweets that Russia intends to end its partnership at ISS due to the sanctions imposed on Russia due to its invasion of the Ukraine.

Rogozin however did not provide any details other than saying:

Specific proposals of Roscosmos on the timing of the completion of cooperation within the framework of the ISS with the space agencies of the United States, Canada, the European Union, and Japan will be reported to the leadership of our country in the near future.

I predict the following:

1. No more barter flights, exchanging Russian and international astronauts on each other’s capsules.
2. No more mutual research on the station.
3. Russia leaves as of ’24, after it adds its remaining modules.

Once those extra modules are launched and installed on the Russian half of ISS, Roscosmos will be more capable of separating its half from ISS and fly it independently. There will be engineering challenges, but this plan will give them two years to address them. It will also give everyone else the time necessary to plan for that separation.

Rocket Lab launches two BlackSky Earth observation satellites

9:41 am

Capitalism in space: Rocket Lab today successfully launched two commercial BlackSky Earth observation satellites using its Electron rocket.

This was Rocket Lab’s the fourth mission for BlackSky, with each launch putting two satellites in orbit. The satellites provide high resolution imagery to commercial and government customers, imagery presently in high demand because of the Ukraine War.

The leaders in the 2022 launch race:

12 SpaceX
8 China
4 Russia
2 ULA
2 Rocket Lab

The U.S. now leads China 19 to 8 in the national rankings.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

SLS dress rehearsal begins, with press coverage limited by NASA

5:56 pm

NASA today began the two-day-long “wet dress rehearsal” countdown of its first SLS rocket, with T-0 expected to occur at 2:40 pm (Eastern) on April 3rd.

The article at the link provides all the information you could want about this rocket, which is now about seven years behind schedule and having a cost so far about $25 billion. This quote however tells us much about the mentality at NASA:

But much of the test will happen without independent press coverage. NASA plans to provide sanctioned updates on the two-day dress rehearsal via the agency’s website and social media accounts, but news media representatives are not being permitted to listen to the countdown activities.

NASA has cited security and export control restrictions for the move. Numerous media representatives requested access to the SLS countdown audio for the wet dress rehearsal. Launch countdown audio feeds for other U.S. rockets, including those developed by private companies and hauling sensitive U.S. military satellites into orbit, are widely available to the news media and the public.

…NASA plans to release only text updates through the weekend. NASA TV will not be airing any live commentary for the final hours of the practice countdown. The agency’s television channel has previously provided live coverage of similar events, such as space shuttle tanking tests. [emphasis mine]

NASA reasons for not allowing anyone to listen to its audio feed — “security and export control restrictions” — is an utter lie. The real reason is that NASA fears the public’s reaction should anything not go exactly as planned. By blocking access to the audio feed, they can hide any faux pas.

NASA’s fear of course is misplaced. This is a test. No one will be surprised or outraged if it doesn’t go perfectly. Better to be open and up front than try to hide problems, because eventually those problems will be revealed and the cover-up will do far more harm to NASA’s reputation than the problems themselves.

The many new private rocket companies, SpaceX, Rocket Lab, Astra, Virgin Orbit, understand this, which is why they all make their primary countdown audio feeds available, though of course they almost certainly have secondary private feeds where engineers can speak more freely. Similarly, NASA did the same in the 1960s, and then during the entire shuttle program.

Now however “export control restrictions” and “security” requires them to be secretive? It is to laugh.

Sunspot update: Sunspot activity continues to outpace predictions

3:23 pm

It is the first of the month, and NOAA has once again updated its monthly graph showing the long term trends in the Sun’s sunspot activity. As I do every month, I post it below, annotated with additional data to provide some context.

In March the Sun continued its unexpected high activity since the end of the solar minimum in 2020. The number of sunspots once again rose steeply, while also exceeding the predicted count for the month. The actual sunspot count for March was 78.5, not 34.1 as predicted. The last time the count was that high for any month was September 2015, when the Sun was just beginning its ramp down from solar maximum.

Strange terrain at the Martian equator

12:41 pm

Strange terrain at the Martian equator
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on January 29, 2022 by the high resolution camera of Mars Reconnaissance Orbiter (MRO). It shows a small portion of the floor of 41-mile-wide Tuskegee Crater, sitting at the Martian equator on the rim of the outlet to the giant canyon Valles Marineris.

I have purposely focused on a section of the color strip, because of its strange green color. Most MRO images are reddish (indicating dust) or blue (indicating coarse rocks or ice). Green seems to me to be rare, and in fact is not even mentioned in the MRO science’s team explanation [pdf] of the colors the instrument produces. Since green is neither dust nor ice, this suggests some form of hard bedrock, with a mineralogy that produces that color.

The overview map below gives some context.

Today’s blacklisted American: Biden’s Labor Board attempts to silence conservative news outlet for making bad Twitter joke

11:50 am

Ben Domenech and The Federalist, blacklisted

National Labor Relations Board

Blacklists are back and the Democrats have got ’em: The National Labor Relations Board (NLRB) is attempting to silence the conservative news site The Federalist for “unfair labor practice” because its publisher Ben Domenech sent out a bad Twitter joke in 2019 about unions, and two lawyers who had nothing to do with the company complained to the NLRB.

The National Labor Relations Board (NLRB) has ordered Ben Domenech—publisher of the conservative website The Federalist…—to take down a June 2019 tweet in which he joked about sending employees who wanted to unionize to work in “the salt mines.” Domenech has refused, and the case is now making its way through the courts.

Domenech’s tweet came in response to news that employees of Vox Media Inc. walked off the job in support of unionization. No one at The Federalist had publicly expressed any interest in unionizing, and two of the website’s six employees filed affidavits attesting that they viewed the tweet as a joke. As far as I know, Domenech doesn’t own any salt mines.

The complainants, leftist lawyers Matt Bruenig (a former NLRB attorney) and Joel Fleming, have never worked for or been personally harmed by the Federalist and were clearly acting to silence their political opponents by taking advantage of NLRB’s overly broad regulations, which allow total strangers to file complaints against businesses they don’t like. The NLRB then moves to harass those businesses.

Will XCOR’s Lynx’s spaceplane be reborn as smallsat launcher taking off from California airport?

9:26 am

Capitalism in space: Wagner Star Industries, a startup that now owns the unfinished Lynx spaceplane that bankrupt XCOR had intended for suborbital tourists flights, has signed a agreement with Paso Robles Municipal Airport in California to launch from there.

Wagner’s plan is to reconfigure Lynx as an unmanned first stage that would launch smallsats into orbit. It would launch and land on a runway from Paso Robles.

Wagner Star is in the process of converting the first Lynx vehicle into a drone so it can begin tests, according to the company’s website. The work involves removing life-support systems that had been installed to support the pilot and passenger and installing equipment for remote controlled operation.

Quetzalcóatl would take off from a runway, release its payload in suborbital space, and then glide back to where it took off. The company said it would be able to launch satellites from any commercial airport runway for $5 million per flight. A suborbital flight without a satellite launch would cost $3 million.

A clever plan. I have doubts about the satellite launches, but using this plane to place drones into high altitude where they could then continue to fly for great distances will almost certainly appeal to the military.

Ronnie O’Sullivan’s record break in Snooker

6:01 pm

An evening pause: Hat tip Phill Oltmann, who has tried several times to explain Snooker to me and failed. The game however appears to be a variation of the U.S. pool game hi-low, though maybe more complicated.

The point is that in the video below, O’Sullivan starts the game and proceeds to clear the table, and he does it in less than six minutes, the fastest time ever. It is amazing to watch.
