Refueling tests begin on Chinese test space station

8:04 am

China has begun the refueling tests between its first unmanned freighter, Tianzhou-1, docked to its test space station, Tiangong-2.

Refuelling tests began at 07:26 Beijing time on Sunday (23:26 UTC Saturday), monitored from the Beijing Aerospace Control Centre (BACC). The refuelling process involves 29 steps and will take five days to complete.

To allow refuelling to take place, the propellant tube and coupling components needed to be perfectly matched after docking, with a margin error of less than 1 millimetre, according to Tianzhou-1 deputy chief designer Chen Qizhong.

The mission involving the Tianzhou and Tiangong spacecraft was designed to prove on-orbit resupply and refuelling technologies and techniques necessary for safe, long-term operation of the Chinese Space Station, which will be permanently crewed by at least three astronauts.

“After refuelling is completed, the residual propellant needs to be drained off. In order to identify security issues during the draining process, it needs to go through a number of tests and verification,” Bai Mingsheng, chief designer of Tianzhou-1, told CCTV+

The article also provides a great deal of information on the station and the freighter.

Vector suborbital rocket test scrubbed

7:43 am

A suborbital test flight of Vector’s orbital rocket was scrubbed on April 6 when a sensor aborted the launch.

The next test flight is scheduled for May 3, after a test April 6 at the company’s test site near the Mohave Desert was scrubbed when a sensor caused an automatic abort, Cantrell said.

Engineers quickly determined the rocket was functional but the company decided not to launch after high winds kicked up. But the rocket is fine, he said, adding that failures are part of the testing process. “We blew a lot of stuff up, trust me,” he said.

The article is more focused on describing in detail the company’s overall status, its fund-raising effort, its future plans, its present operation. This tidbit about the test launch was buried in it. That the flight didn’t fly is not a bad mark on the company, at this point. However, they are under pressure to fly as soon as possible in order to demonstrate success, and delays work against them.

Airbus-Safran gets go-ahead to build first Ariane 6 test rocket

8:30 am

Capitalism in space: The European Space Agency (ESA) has given Airbus-Safran the go-ahead to build the first Ariane 6 rocket, which will be used for ground tests.

It is really important to recognize how this article illustrates the major things that have occurred in how Europe is builds its rockets. Note first that Arianespace is not mentioned at all, even though government bureaucracy has been in charge of ESA’s commercial business for decades. It is not in control any longer and is thus irrelevant. Note also that the design was created solely by Airbus-Safran, and that the only thing ESA did was approve it. The agency did not micromanage it, or revise it, or insist on changes, as would have been the case less than three years ago. Instead, it appears they essentially rubber-stamped it, leaving this work entirely to the private company, which in the end will operate and sell the rocket entirely for profit, while also providing ESA its needed launch vehicle.

At first glance, it appears that the ESA has adopted here the recommendations that I made in my policy paper, Capitalism in space:. In truth, they made these policy changes well before my paper was even written, which helps illustrates forcefully their universal correctness. If you want things built well and efficiently, you give people ownership of their work, you let them create it, and you get out of the way.

Or to use that forgotten word, you let freedom work its magic.

China’s first unmanned freighter successfully docks with test station

8:04 am

Tianzhou-1, China’s first unmanned space freighter, today successfully docked with that nation’s test station module, Tiangong-2.

Tianzhou-1, China’s first cargo spacecraft, which was launched Thursday evening from Wenchang Space Launch Center in south China’s Hainan Province, began to approach Tiangong-2 automatically at 10:02 a.m. Saturday and made contact with the space lab at 12:16 p.m.

The Tianzhou-1 cargo ship and Tiangong-2 space lab will have another two dockings. The second docking will be conducted from a different direction, which aims to test the ability of the cargo ship to dock with a future space station from different directions. In the third docking, Tianzhou-1 will use fast-docking technology. It normally takes about two days to dock, while fast docking will take only six hours.

This testing program by China is very well thought out. They are performing a whole range of docking tests, and they are doing it with an unmanned prototype station that well simulates the full scale station they eventually plan to build.

The Israeli finalist in the Google Lunar X-Prize is out of the running

10:19 pm

The Israeli team for the Google Lunar X-Prize, one of the five finalists, can no longer win the race because its SpaceX launch will not take place before the end of the year.

SpaceIL, formed by veterans of the Israeli tech sector, will not be able to launch by the year-end deadline set by the race’s organizers, according to Spaceflight Industries, the space transport company hired to carry the team’s spacecraft on a Falcon 9 rocket launch it purchased from SpaceX.

A Spaceflight executive tells Quartz that SpaceIL’s rocket is still in the launch queue but will be unable to launch before 2018, effectively scotching SpaceIL’s chance at the contest barring a last-minute extension to the deadline.

The article does a nice job of summarizing the situation for all five finalists, all of which appear to have problems that could prevent them from flying before the deadline at the end of 2018. It also notes that an extension could also be granted, as has happened twice before.

France settles union dispute in French Guiana

10:10 pm

The union strike that has stopped all Arianespace launches from French Guiana for the past month has been settled.

The article provides no details on the settlement itself. Instead, it outlines the company’s intention to complete all the scheduled launches they had planned for 2017.

Update: This story outlines the basic agreement.

It authorises an emergency relief plan of up to 2.1 billion euros, which includes funds for security, education, healthcare and business aid.

France had already approved 1.1 billion in aid for French Guiana at the beginning of April. The additional funds were offered to meet demands made by the collective and local representatives, who rejected the government’s initial offer.

France will prioritise the implementation of the spending plan, said Bareigts, who described the agreement as a “decisive day for the future of Guiana”.

Essentially, this is a payoff to the unions and group in French Guiana that organized the strike. I am sure a lot of the money will go for good purposes, but I am even more sure that a majority of it will simply end up in the pockets of the strike organizers, doing little to help the people of French Guiana themselves.

Trump signs commercial weather satellite bill

4:14 pm

Capitalism in space: President Trump today signed the new law that strongly encourages NOAA to begin using privately acquired weather data.

Among the bill’s provisions is language formally authorizing the National Oceanic and Atmospheric Administration to purchase weather data from commercial satellite systems. The bill authorizes NOAA to spend $6 million a year in fiscal years 2017 through 2020 for a pilot program of data purchases to evaluate the effectiveness of commercial data to support weather forecasting.

NOAA has already started such a pilot program using $3 million appropriated to the agency in fiscal year 2016. In September 2016, NOAA awarded contracts to GeoOptics and Spire, with a combined value of a little more than $1 million, for GPS radio occultation data.

These are only baby steps. At this time NOAA’s bureaucracy views commercial space the same way that NASA did back in 2004: it is a threat and also incapable of doing the job. Since NOAA today, like NASA in 2004, has been unable to do the job very well itself, its ability to argue against private space is limited. Expect the pressure to build for NOAA to hand over more and more of its weather-gathering work to private companies.

How Russia’s next ISS module got contaminated

9:44 am

Russia’s next module for ISS, MLM or Nauka, has been delayed years because of the discovery of sawdust sized metal particles throughout the module’s propulsion system. This article describes how this happened, showing the incredibly incompetence and bad quality control that caused it.

At the time, workers at Khrunichev were cutting pipelines and removing other components of the module’s propulsion system, in order to reconfigure it from its original role as a backup to the Zarya FGB module into the MLM. For example, a set of six tanks, which would be used for refueling of the ISS during the FGB mission, were removed from the exterior of the spacecraft in order to make room for scientific instruments and for the attachment of the European Robotic Arm, ERA.

The official conclusion of the probe said that the contamination had stemmed from the “lack of methodological and technological support for the operations of cutting pipeline connections in the pneumatic and hydraulic system, PGS, which was needed to guarantee the meeting of requirements for ensuring the sterility of the internal cavities in the pipelines and system hardware.” It is essentially bureaucratic speak for letting metallic dust formed during sawing off the lines pour into the interior of the remaining components.

According to one legend circulating at GKNPTs Khrunichev, the workers who were sawing off pipelines from the module thought they were dismantling the entire spacecraft for scrap. That story would sound completely unbelievable if not for other almost as incredible incidents of carelessness, poor quality control and incompetence within the industry in recent years, such as the installing navigation sensors on a Proton rocket in the upside down position or loading a Block DM-03 space tug on another Proton with too much propellant.

Read the whole story. It is most revealing of the overall systematic problems within Russia’s aerospace industry.

China launches first unmanned freighter in test flight

7:03 pm

China today successfully launched its first unmanned cargo freighter, Tianzhou-1.

After entering orbit, according to CCTV-Plus interviews with Chinese space officials, Tianzhou-1 is slated to conduct a first docking with Tiangong-2 in a few days. The two spacecraft will then have a two-month in-orbit flight to test the liquid-propellant refueling as well as the cargo spaceship’s control of the combined vehicles, CMSA officials said.

The two spacecraft will also fly separately for three months, during which time the cargo spaceship will complete its own space science experiments. Then the two will have the third docking to test the automatic fast-docking technology, a test to complete the docking within 6 hours.

This was also the second launch of their most powerful rocket, Long March 7, and the second launch from their new spaceport at Wenchang.

Private company builds high resolution space radar facility in Texas

6:36 pm

Capitalism in space: A private company, Leo Labs, has built a high resolution space radar facility in Midland, Texas, aimed at providing satellite companies precise location information of their orbiting satellites as well as the space junk that might threaten them.

It is not clear from the article or the company’s webpage whether they are funded by the federal government or by private capital investment. Up until now this data has been routinely gathered by the U.S. military, though obtaining it has I think been somewhat difficult due to security concerns. It seems this company is trying to compete with the government in offering a better data stream that is also easier to obtain.

Posted over Poland during my return flight from Israel.
