DARPA’s satellite servicing mission adrift

9:16 am

Capitalism in space? DARPA’s program to test a satellite servicing mission appears in serious and complex trouble with the termination by Maxar (previously called SSL) of its contract to build the structure, or “bus”, of the robot.

What makes this more complicated is that the company building the actual servicing payload is continuing its work.

While Maxar will no longer be providing the satellite bus, work on the servicing payload continues. Among the companies involved in that effort is Praxis, a company handling planning for mission operations of the RSGS servicing system, such as how the system will safely grapple the target satellite. “For our day-to-day operations, that hasn’t really affected us. We’re pretty far along on the payload development,” said Tony Marzi, general manager of Praxis, during a presentation at the MIT New Space Age Conference at the Massachusetts Institute of Technology here March 15.

DARPA is thus calling for proposals to launch this payload.

The irony here is that this DARPA project was under criticism from the start, even to the point that a competing satellite servicing company, Orbital ATK, sued the agency. That company, now part of Northrop Grumman, was building its own privately funded servicing robot, and considered DARPA’s effort to be unfair in that it provided direct government subsidies to its competitors.

While Orbital ATK lost its suit, it now appears it has won the competition — assuming it eventually launches its own mission.

OneWeb raises $1.25 billion

8:54 am

Capitalism in space: Following the launch of the first six satellites for its 650 satellite constellation to provide worldwide internet services, OneWeb today announced that it has successfully raised $1.25 billion in new investment capital.

…it has secured its largest fundraising round to date with the successful raise of $1.25 billion in new capital. This brings the total funds raised to $3.4 billion. This round was led by SoftBank Group Corp., Grupo Salinas, Qualcomm Technologies Inc., and the Government of Rwanda.

The new funds, following the successful first launch of OneWeb’s satellites, enable the company to accelerate the development of the first truly global communications network by 2021.

…OneWeb’s satellites, produced through its joint venture with Airbus doing business as “OneWeb Satellites”, will ramp-up production this spring at its new, state-of-the-art manufacturing facility in Exploration Park, Florida. Following the company’s successful launch of satellites on February 27th, OneWeb will embark on the largest satellite launch campaign in history. Starting in Q4, OneWeb will begin monthly launches of more than 30 satellites at a time, creating an initial constellation of 650 satellites to enable full global coverage. After this first phase, OneWeb will add more satellites to its constellation to meet growing demands.

This puts OneWeb significantly ahead of everyone else, including SpaceX, in the race to launch the first space-based system for providing internet services. Their planned launch pace also illustrates why there is a flood of new smallsat rocket companies. They, and others, have a clear need for launch services, which presently cannot be provided by the existing launch companies.

First SpaceX Starship Hopper tests this week?

8:44 am

Capitalism in space: According to this news story on Sunday, SpaceX could attempt its first Starship Hopper tests this week.

A sheriff hand-delivered road closure notices to residents on Friday, according to a local resident. The document warned locals that SpaceX will “conduct testing” as soon as Monday, March 18.

The article also cites a flurry of tweets about the hopper that Elon Musk made on Sunday. Unfortunately, Musk’s tweets do not say anything about tests this week.

Regardless, it appears that SpaceX might actually be close to beating the schedule it announced for these tests back in November, when Musk said they were aiming for tests in June. If so, this would be a remarkable achievement, one that is almost unheard of in the aerospace launch industry.

New Zealand threatens prison for publishing material showing this week’s shootings

3:36 pm

They’re coming for you next: Even as the New Zealand government has issued threats of ten year prison terms for sharing or even possessing the video’s from the mosque shooting this week, the large internet corporations are moving in to support this censorship.

Terrorist Brenton Tarrant used Facebook Live to broadcast the first 17 minutes of his attack on the Al Noor Mosque in Christchurch, New Zealand at approximately 1:40 p.m. on Friday – the first of two mosque attacks which left 50 dead and 50 injured.

Copies of Tarrant’s livestream, along with his lengthy manifesto, began to rapidly circulate on various file hosting sites following the attack, which as we noted Friday – were quickly scrubbed from mainstream platforms such as Facebook, YouTube, Twitter and Scribd. YouTube has gone so far as to intentionally disable search filters so that people cannot find Christchurch shooting materials – including footage of suspected multiple shooters as well as the arrest of Tarrant and other suspects.

On Saturday, journalist Nick Monroe reported that New Zealand police have warned citizens that they face imprisonment for distributing the video, while popular New Zealand Facebook group Wellington Live notes that “NZ police would like to remind the public that it is an offence to share an objectional publication which includes the horrific video from yesterday’s attack. If you see this video, report it immediately. Do not download it. Do not share it. If you are found to have a copy of the video or to have shared it, you face fines & potential imprisonment.”

Distributing this killer’s video to me seems more than odious, but having the government and these internet giants team up to censor it, while also censoring distribution of his manifesto, which showed clearly that this madman was no right wing Trump supporter, is even more unconscionable. Such censorship only serves to encourage further such attacks, as it shows that future attackers can have far more influence and impact than merely killing fifty people. They can shut down free speech and western civilization worldwide.

This censorship also allows the liberal Democratic press to continue to push the lie that this madman was instigated by Trump, without no facts to challenge it.

That dark age sure is coming, and it looks like it is getting here faster every day.

ULA’s Delta 4 rocket launches Air Force communications satellite

9:19 pm

Capitalsm in space: ULA yesterday used its Delta 4 rocket to successfully place in orbit an Air Force communications satellite.

This is one of the last launches of the the Delta 4 member in the Delta rocket family.

The mission marked the next-to-last flight of the Delta 4 rocket variant with a single first stage core — known as the Delta 4-Medium — as ULA begins retiring segments of its launcher family in preparation for the debut of the new Vulcan booster, which the company says will be less expensive than the existing Atlas and Delta fleet.

Gary Wentz, ULA’s vice president of government and commercial programs, said the company’s decision in 2014 to retire the Delta 4-Medium was intended to reduce the company’s costs. “We started looking at the products that we were providing, and found that maintaining these two families of launch vehicles, both the Delta and the Atlas, through this period decreased our flight rate, and therefore increased our costs,” Wentz said. “That really drove it, based on the competitive industry we’re in, trying to maximize our competitiveness.”

The Delta 4-Medium family provides the same range of lift capability as the less expensive Atlas 5 rocket. The Delta 4-Heavy, which will remain operational through at least the early-to-mid-2020s, uses three Delta 4 first stage cores bolted together to haul heavier payloads to orbit than any of the Atlas 5 configurations.

The leaders in the 2019 launch race:

3 SpaceX
3 China
2 Europe (Arianespace)
2 Russia
2 ULA

In the national rankings, the U.S. has now widened its lead on China to 5 to 3.

Note that two different American companies are matching the launch numbers of three other whole countries. This I think illustrates well the power of freedom and competition. Rather than have a single nationalized rocket system (as was attempted in the 2000s when Boeing and Lockheed Martin created ULA, then the only American rocket company), the U.S. has transitioned back to its roots, allowing freedom to produce multiple companies competing for both private and government business. This has reduced costs, encouraged innovation, and ended up producing more jobs and wealth.

On the radio

3:28 pm

I will be visiting with Robert Pratt today at 6:05 pm (Eastern) for an hour on his Texas radio show, Pratt on Texas, aired on 790-AM KFYO in Lubbock, 1470-AM KYYW in Abilene, and 1290-AM KWFS in Wichita Falls.

I expect we will be discussing SLS and the effort of the corrupt culture of Washington to keep that unproductive boondoggle alive.

The Washington Empire strikes back!

11:45 am

In response to the revelation earlier this week by NASA administrator Jim Bridenstine that the agency is considering replacing SLS with commercial rockets for Orion’s first unmanned lunar test mission in June 2020, the swamp in Washington quickly rallied to SLS’s defense.

Not surprisingly, porkmeister Senator Richard Shelby (R-Alabama) led the charge:

“While I agree that the delay in the SLS launch schedule is unacceptable, I firmly believe that SLS should launch the Orion,” Sen. Richard Shelby (R-Ala.) said in a statement to SpaceNews.

This was followed by statements from industry groups and other lawmakers, all supporting SLS. Next came Bridenstine himself, who emphasized his strong support of SLS at a conference yesterday, then issued a memo to NASA employees reiterating that support.

As far as I can tell, the only way SLS will eventually die is when private companies begin doing things that SLS is designed for, for less money and faster, and for profit. And that won’t happen if this Washington swamp has its say. Rather than see an American success, these cronies have made it clear in the past decade that they will work to squelch any such success if poses any threat to their boondoggles. And it appears now that they are moving to block Bridenstine’s suggestion for that first Orion flight.

Whether this new big government campaign against private enterprise succeeds however is not clear.

Rogozin: Russia and U.S. to use both countrys’ manned capsules to ISS

10:04 am

According to statements made today by Roscosmos head Dmitri Rogozin, Russia and the United States now plan to send their astronauts to ISS using both the Russian and American capsules.

“We agreed with the NASA leadership to preserve our agreements and principles of cooperation. Astronauts will fly on board Soyuz, and we will use US spacecraft,” he said, adding that US spacecraft will need to get certification first.

According to the Roscosmos head, this will create an alternative in manned space missions to the International Space Station.

This suggests that once the U.S. commercial capsules are operational the two countries will return to the situation that existed when the shuttle was flying, with Americans sometimes flying on Russian spacecraft and Russians sometimes flying on American spacecraft. Under that set-up however, there was no direct payment by the U.S. for its seats on those Russian spacecraft, since it was a straight embargo deal.

Will this be the case now? We shall see. NASA for the past two decades has increasingly worked to keep the Russian space effort operating, sometimes even to the detriment of American efforts.

If Russia no longer gets money from the U.S. for its space flights it simply might not be able to afford to fly. We really won’t need them, but for a number of reasons we might decide to pay them to keep them in the game, both from a foreign policy perspective as well as some underhanded motives that are divorced from considerations of the national interest.

Unfortunately, separating these two issues has become increasingly difficult, especially because of the spreading corruption that is taking over the Washington establishment. This establishment more and more cares little for this country. Instead, it puts its own interests and power first, often in direct violation of the Constitution and the fundamental principles that founded the United States. Under these conditions that establishment might decide it is better to help the Russians, even if it hurts America and its citizens.

A pond on Bennu

9:42 am

Pond on Bennu
Click for full resolution.

The OSIRIS-REx science team has released new high resolution images of one particular area on Bennu’s northern hemisphere. The image on the right, cropped and reduced to post here, shows what they label a “pond of regolith,” seen as the relatively smooth area in the upper left.

This is not literally a pond, but instead is a low-lying spot where smaller particles have settled over time, producing a flattish area that looks, and in some ways, resembles a pond or puddle, only in this case the material isn’t water but fine-grained dust or pebbles.

On March 19 the science team will be presenting their initial results at a special session at the 50th Lunar and Planetary Science Conference in Texas. That same day they will hold a press conference summarizing the most interesting aspects of those results. Stay tuned.

Chinese lunar rover and lander enter their third lunar night

9:21 am

The Chinese lunar rover Yutu-2 and its lander Chang’e-4 have gone into hibernation as they enter their third lunar night on the far side of the Moon.

According to Chinese news reports, both spacecraft have now exceeded their nominal lifespan.

With all systems and payloads operating well, the Yutu-2 team will continue roving and science data collection on lunar day 4 of the Chang’e-4 mission, according to a [Chinese] announcement.

Yutu-2 added 43 meters to its overall drive distance in its third day of activities, continuing a path to the northwest of the landing site, which was recently named ‘Statio Tianhe’ by the International Astronomical Union. The rover just covered seven meters between waking for lunar day 3 on Feb. 28 and Mar. 3, during which time it navigated carefully toward a 20 centimeter diameter rock in order to analyze the specimen with an infrared and visible light spectrometer to determine its origin.

I am struck by how tentative the Chinese and their rover appear. The first Russian lunar rover, Luna 17, traveled 6.5 miles in eleven months. The second, Luna 21, traveled 23 miles in four months. At the pace Yutu-2 is setting, it will not come close to these mileages. Moreover, my impression of Chinese space technology in the past decade has been that it is quite robust. This tentativeness thus surprises me. Maybe because this is a government project they are simply covering their butts should something go wrong, and thus making believe the rover is more delicate than it really is.

As Scotty on Star Trek once said, “Always under predict, then over perform.” We might be seeing that pattern here.

Curiosity has another computer crash

8:53 am

Since March 6 all activity from Curiosity seemed to stop, with no images and no science team updates. The reason? The rover had experienced another computer crash and reboot:

Curiosity experienced a computer reset on its Side-A computer on Wednesday, March 6, 2019 (Sol 2,339), that triggered the rover’s safe mode. This was the second computer reset in three weeks; both resets were related to the computer’s memory.

The mission team decided to switch from the Side-A computer back to the rover’s Side-B computer, which it operated on for most of the mission until November of 2018. Side-B recently experienced its own memory issue; the team has since further diagnosed the matter, reformatting the Side-B computer to isolate areas of “bad” memory. As of today, Curiosity is out of safe mode, and the team is configuring the rover for new science operations in the clay unit. Curiosity is expected to return to science operations as early as Wednesday.

This news is worrisome. The track record for spacecraft with increasing computer problems is that they never get better. Instead, the problem steadily worsens until operations become limited or even impossible. In the meantime engineers work wonders to extend the mission, but in the end this is a battle they appear to always lose.

We are beginning to see this pattern with Curiosity. Both of its computers have now experienced problems. It appears they have a better handle on the problems with the back-up computer (Side-B), so that is why they have switched back to it. Should its own memory issues continue to deteriorate however the rover will be in serious trouble, as the Side-A computer has proven to be very unreliable.
