Watch a rocket tank being built, mostly by robots

10:39 am

Capitalism in space: The video below the fold shows the process by which Interorbital Systems built a rocket test tank for the Neptune smallsat rocket it is developing. It is definitely worth watching if you want to see the future of complex manufacturing. Robotic equipment does most of the work, in a precise manner that would be impossible for humans, which therefore allows for the construction of engineering designs that were previously impossible or too expensive. Now, such designs can be built relatively cheaply, and repetitively.

Development at SpaceX’s Texas spaceport to pick up in 2018

10:31 am

Capitalism in space: Though construction at SpaceX’s Texas spaceport has been slower than expected, the company expects to accelerate development in 2018.

According to SpaceX, [people] won’t have to wait much longer for an increase in activity at the future spaceport. The recently installed antennas at Boca Chica are expected to be operational next year — although they’ll initially track flights blasting off from elsewhere — and the company also indicated development of the overall launch complex should pick up. “Even as our teams worked to modernize and repair our launch complexes in Florida so that we could reliably return to flight for our customers, SpaceX invested $14 million into the South Texas project,” said Gleeson, the company’s spokesman.

“Now, with our launch construction projects in Florida wrapping up by early 2018, SpaceX will be able to turn more attention to our work in South Texas,” he said.

In other words, once SpaceX has got its two launchpads in Florida both up and running, including the first use by the Falcon Heavy of one of those pads, the company will then be able to shift its launchpad operations down to Texas.

The article outlines in detail many of the reasons the development has been slow, but I think the issues highlighted in the quote above, issues I had not considered previously, might be the most important. After the September 2016 launchpad explosion in Florida, SpaceX had to divert resources to repairing that pad, which put Boca Chica on the back burner.

Moon Express will launch to Moon in 2018, regardless of X-Prize deadline

10:23 am

Capitalism in space: The head of Moon Express said yesterday that the company will definitely fly its privately-built lunar rover to the Moon in 2018, regardless of whether that flight occurs in time to win the Google Lunar X-Prize.

The company is competing for the Google Lunar XPRIZE which has a $20 million reward for the first private firm to put a spacecraft on the moon, travel 500 meters, and transmit high definition video and images back to earth. The deadline for doing this is March 2018.

Jain did not give an exact date for the launch and said that getting the prize isn’t necessarily the main priority.

It appears to me that the main reason they will not make the deadline is because Rocket Lab’s Electron rocket won’t be ready in time. This is why its second test launch in the coming weeks is so important. If successful, it increases the chances that Moon Express will be able to meet the X-Prize deadline.

Europe commits $107 million for new rocket and space plane

8:56 pm

The European Space Agency (ESA) today allocated $107 million to develop both a new larger version of its Vega rocket as well as an orbital version of the spaceplane engineering test vehicle flown in 2015.

The Vega-E will be larger and will give them another rocket capable of competing for launch business, but the space plane project is more interesting.

ESA awarded 36.7 million split between Avio and Thales Alenia Space Italy for Space Rider, an unmanned spaceplane capable of lifting 800 kilograms to LEO for missions up to two months. A single Space Rider should be capable of six missions with refurbishing, according to Thales Alenia Space.

Space Rider leverages technology from ESA’s Intermediate Experimental Vehicle (IXV), which performed a suborbital mission in February 2015, landing in the Pacific Ocean. Unlike its predecessor, Space Rider is designed for ground landings. ESA tasked Thales Alenia Space with building Space Rider’s reentry module based on the IXV.

It seems Europe wants its own version of X-37B and Dream Chaser.

Portrait of Lotte, 0 to 18 years

6:01 pm

An evening pause: Somehow, to me, this seems a fitting introduction to the holiday season. From the youtube website, “Lotte from the Netherlands (Utrecht) becomes 18 years old in this film! Dutch filmmaker and artist Frans Hofmeester has been filming and photographing his children Lotte and Vince since birth. Every week the images are shot in the same style.”

House panel approves concealed carry reciprocity for all 50 states

12:53 pm

The House Judiciary committee yesterday approved a nationwide law that would require states to recognize the legality of concealed carry licenses from other states.

The legislation allows firearm owners with a concealed carry permit issued by their home state to carry the firearm into any other state (all allow some form of concealed carry, although many are highly restrictive). The gun owners wouldn’t have to reveal they are carrying a weapon, though the bill does require they be eligible to possess a firearm under federal law (which requires a background check), carry a valid photo identification and a concealed carry permit. Gun owners from states that don’t require a concealed carry permit will need to obtain some credential from their home state to take advantage of the new law’s provisions. What form that would take isn’t specified in the House bill.

The bill still has to pass both the House and the Senate. A similar bill in the Senate already has 38 co-sponsors.

The article is typical for the modern mainstream press. It spends a lot of time getting quotes from numerous anti-gun groups and Democratic politicians, but never highlights the numerous examples in recent years where entirely innocent individuals have had their lives ruined because they entered places like New Jersey, DC, and New York with a gun that was totally legal in their home states.

More delays in Democratic IT scandal

10:52 am

The attorney for Imran Awan, the computer specialist who had worked for numerous Democratic congressmen, including Debbie Wasserman Schlutz and is now charged with bank fraud, has caused a month delay in the court case in an effort to block the use of a laptop and its contents as evidence.

Wasserman Schultz fought to prevent law enforcement from looking at the laptop, threatening a police chief with “consequences” and implying it was “a member’s” laptop. She hired an outside lawyer, Bill Pittard, who specializes in the “speech and debate” clause of the Constitution that is designed to protect lawmakers from persecution for political stances, but lawmakers have used to try to stymie criminal probes in the past.

Now, it is Awans’ lawyers who are seeking the right to keep information in the backpack, including the “hard drive,” from being used as evidence.

The Awan attorneys are claiming that the laptop and all other information found in the backpack should be blocked as evidence because they fall under attorney-client privilege. This is absurd. If the court agrees with this interpretation, it will allow criminals to declare almost all evidence inadmissible, just by claiming it was communications between lawyer and client.

Based on all this effort to keep law enforcement from seeing what’s on that laptop, I suspect it contains some very damning information, both to Awan as well as to Wasserman Schultz and many other Democrats who had hired Awan.

Someone in India finally reads its proposed oppressive space law

9:25 am

Link here. The analysis of India’s proposed new space law [pdf] is generally very negative, but strangely it avoids entirely the bill’s worst aspect, its requirement that everything launched by India into space must belong to the government.

Instead, the author focuses on how the bill’s broad language fails to deal with specific issues of insurance, the licensing of different kinds of space activities, and environmental pollution. In other words, it appears he cannot see the forest because of the trees.

In the end, however, in concluding that the bill as written does not serve the private sector he does make one good suggestion that I hope the Indian government takes to heart.

It will not do justice to the entrepreneurial community if this Bill is implemented as is. One of the exercises that can be conducted to align the Bill to enable a competitive ecosystem for commercial space in India is to conduct a review of international best practices in managing the space value chain and inducting them within the Bill.

In other words, read what other nations like the U.S. and Luxembourg are doing to encourage their private commercial space sector. India might find that the last entity allowed to own something in space should be the government.

Chinese space probe detects possible dark matter signal

8:56 am

The uncertainty of science: A Chinese space probe designed to measure cosmic rays has detected a pattern that could be evidence of the existence of dark matter.

Researchers launched the spacecraft from the Jiuquan Satellite Launch Center in the Gobi Desert, about 1600 kilometers west of Beijing, in December 2015. Its primary instrument—a stack of thin, crisscrossed detector strips—is tuned to observe the incoming direction, energy, and electric charge of the particles that make up cosmic rays, particularly electrons and positrons, the antimatter counterparts of electrons. Cosmic rays emanate from conventional astrophysical objects, like exploding supernovae in the galaxy. But if dark matter consists of WIMPs, these would occasionally annihilate each other and create electron-positron pairs, which might be detected as an excess over the expected abundance of particles from conventional objects.

In its first 530 days of scientific observations, DAMPE detected 1.5 million cosmic ray electrons and positrons above a certain energy threshold. When researchers plot of the number of particles against their energy, they’d expect to see a smooth curve. But previous experiments have hinted at an anomalous break in the curve. Now, DAMPE has confirmed that deviation. “It may be evidence of dark matter,” but the break in the curve “may be from some other cosmic ray source,” says astrophysicist Chang Jin, who leads the collaboration at the Chinese Academy of Science’s (CAS’s) Purple Mountain Observatory (PMO) in Nanjing. [emphasis mine]

I must emphasize the large uncertainty here. They have not detected dark matter. Not even close. What they have detected is a pattern in how the spacecraft is detecting cosmic rays that was predicted by the existence of dark matter. That pattern however could have other causes, and the consistent failure of other efforts to directly find dark matter strengthens the possibility that this break is caused by those other causes.

Soyuz failed because it was programmed for Baikonur, not Vostochny

8:39 am

It now appears that the Soyuz rocket failure this week occurred because the Fregat upper stage had not been programmed for a launch from Vostochny.

Although the information is still preliminary, it is increasingly clear that all the hardware aboard the Fregat upper stage performed as planned. But, almost unbelievably, the flight control system on the Fregat did not have the correct settings for the mission originating from the new launch site in Vostochny, as apposed to routine launches from Baikonur and Plesetsk. As a result, as soon as Fregat and its cargo separated from the third stage of the launch vehicle, its flight control system began commanding a change of orientation of the stack to compensate for what the computer had perceived as a deviation from the correct attitude, which was considerable. As a result, when the Fregat began its first preprogrammed main engine firing, the vehicle was apparently still changing its attitude, which led to a maneuvering in a wrong direction. [emphasis mine]

This reminds me of the NASA’s epic failure with Mars Climate Orbiter in 1998, where some programming used the metric system and other programming used the English system, and no one noticed.
