Capitalism in space: It appears, from a Elon Musk tweet, that SpaceX has obtained a second boat to catch its rocket fairings for reuse.
Based on previous comments by Musk, the company is now on the verge of recovering and reusing about 70% of its Falcon 9 rockets during each launch. I’d say that’s pretty good, especially considering industry rocket experts have been saying for half a century that none of this was even possible or practical.
For your viewing pleasure, below is a just released short video showing the 50 second 1000 foot high vertical test on August 9 by the Chinese company Linkspace.
Chandrayaan-2 today successfully completed its last Earth perigee burn, raising its orbital apogee so that it will enter the Moon’s gravitational sphere of influence on August 20th.
Chandrayaan-2 will approach Moon on August 20, 2019 and the spacecraft’s liquid engine will be fired again to insert the spacecraft into a lunar orbit. Following this, there will be further four orbit maneuvers to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface.
…Subsequently, Vikram lander will separate from the orbiter on September 02, 2019. Two orbit maneuvers will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface on September 07, 2019.
Vikram will be doing the hardest part, the landing.
The National Science Foundation has awarded the Arecibo radio telescope in Puerto Rica a $12.3 million grant to pay for needed repairs and upgrades following the hurricane damage from 2017.
The money will pay for the following work:
- Repairing one of the suspension cables holding the primary telescope platform, ensuring long-term structural integrity of one of the main structural elements of the telescope.
- Recalibrating the primary reflector, which will restore the observatory’s sensitivity at higher frequencies.
- Aligning the Gregorian Reflector, improving current calibration and pointing.
- Installing a new control system for S band radar, which is part of the microwave band of the electromagnetic spectrum.
- Replacing the modulator on the 430 MHz transmitter, increasing consistency of power output and data quality.
- Improving the telescope’s pointing controls and data tracking systems.
Most of this looks to be very basic maintenance, which suggests the telescope is still very starved for funds.
An evening pause: The dancing here is as good if not better than anything you will see in an Astaire & Rogers movie.

Riot police today attacked the Hong Kong airport protesters, storming into their midst with batons and pepper spray.
CNN International reported, following the police operation that reporters witnessed at least four arrests and that officers appeared to be targeting specific people. To get through the protesters, police used pepper spray and batons to push back the crowd. According to an official statement from Hong Kong police, airport officials requested that the riot officers enter the airport to rescue a man who protesters had apprehended and accused of being an undercover police officer. The South China Morning Post also reported that the airport received a court injunction requesting police remove the protesters from the premises, though Hong Kong police did not issue an official statement to that effect and officers left without clearing out every protester.
Pro-democracy protesters shut down the airport Tuesday for the second day in a row, forcing administrators to cancel all flights, in a bid to get the China-controlled Hong Kong government to listen to their demands. Some protesters appeared to panic and target others suspected of working for the communist government after officials admitted this weekend that officers had dressed up as protesters to infiltrate the marches.
So far this attack today does not appear to be an effort to shut the protest down with violence. It appears that after extracting two men, possibly pro-China reporters, the police retreated, though the authorities are now limiting access to the airport, probably with the goal of starving the protest with a lack of new supporters.
A very sad messy situation. The Chinese want to impose its tyranny on Hong Kong. Hong Kong’s citizens want to remain free. The result are street protests that can only turn violent, one way or the other, because China’s government is very unlikely to back down.
In mining the Rosetta archive of images of Comet 67P/C-G, an amateur astronomer has discovered a twelve-foot-diameter chunk of material that had broken from the comet and was in orbit around it.
Modelling of the Rosetta images indicates that this object spent the first 12 hours after its ejection in an orbital path around 67P/C-G at a distance of between 2.4 and 3.9 km from the comet’s centre. Afterwards, the chunk crossed a portion of the coma, which appears very bright in the images, making it difficult to follow its path precisely; however, later observations on the opposite side of the coma confirm a detection consistent with the orbit of the chunk, providing an indication of its motion around the comet until 23 October 2015.
While it is not really unusual for their to be small objects in the coma of the the comet, orbiting it, this is apparently the largest so far found. That they missed it initially is also not surprising, considering the amount of data they were gathering in such a short time.
Capitalism in space: Having found that Bigelow’s privately built ISS module BEAM has exceeded its design capabilities, NASA has now decided to leave it docked to ISS for at least five more years, using it as a storage bin.
BEAM cost NASA a whopping $17 million, considerably less than it has traditionally spent (a billion-plus) for its previous ISS modules, designed and built under full NASA supervision.
China’s semi-private company Linkspace on August 9 successfully completed its highest vertical take-off and landing test flight yet, flying to a height of 300 meters.
The 8.1-meter-tall, 0.65-meter-diameter, 1.5-metric-ton rocket reached an altitude of 300.2 meters during its 50-second flight before making a powered descent and vertical landing with an accuracy of 0.07 meters, Linkspace CEO Hu Zhenyu stated on Sina Weibo, a Chinese Twitter-like service. The launch follows two tests reaching 20 and 40 meters in March and April respectively.
The latest test was carried out at a new facility in the Lenghu region of Qinghai province in the northwest of the country. Chinese magazine Future Aerospace states that the RLV-T5 is powered by five variable-thrust rocket engines which use ethanol and liquid oxygen, a propellant combination used by the German V2 rockets.
Unlike the other new semi-private Chinese commercial companies, Linkspace appears to be using liquid fueled rockets, rather than depending on military solid rocket technology. This suggests to me that this company, aggressively supervised by the Chinese government, will eventually be going for both the small and big orbital business, not just smallsats.
I also give credit to the Chinese, both their government and this company, for quickly facing reality posed by SpaceX’s capabilities and working to develop their own rocket reusability as fast as possible. In contrast, Europe, Russia, and the old American big rocket companies have mostly sat twiddling their thumbs, making believe that this capability is either irrelevant, or still impossible, even as SpaceX has taken all of their business because it can undercut their prices significantly as it repeatedly re-uses its Falcon 9 first stages.
Blue Origin has submitted a protest to the Government Accountability Office (GAO) yesterday about the Air Force plan to pick two launch providers now for all its satellite launches after 2026.
According to a copy of the protest obtained by FLORIDA TODAY, the ordering period for the launches would run from 2020 to 2024 and ultimately select two contractors for flights beginning in 2026.
“The most recent market research, however, indicates the total global addressable space launch market, including NSSL launches, could support three or even four U.S. launch companies,” the protest reads. “Even the Agency’s own LSP source selection support contractor – the Aerospace Corporation – predicts that the space launch market has significant potential to suffer from a launch capacity shortfall because U.S. and foreign government launches will require most of the available launch capacity.”
I couldn’t agree with Blue Origin more. The Air Force wants to limit competition in the 2020s to only two companies, which will almost certainly be ULA and SpaceX since they are the only two presently flying, when by the 2020s there might be several more companies available providing competition that can lower the price.
There is no reason for the Air Force to make this decision now. None. When they need to order these launches in the early 2020s they should open that bidding process to all comers, and pick appropriately, then. Everything about this Pentagon plan stinks, reeking of the corruption that permeates Washington. I even wonder if some people have gotten pay-offs in connection with the decision to favor only two companies. It wouldn’t surprise me. (I myself have been offered money to let military lobbying companies ghostwrite op-eds using my name, supporting this Air Force plan, offers that I very bluntly turned down.)
Also, even if Blue Origin’s protest now fails, expect whoever doesn’t get picked by the Air Force now to file lawsuits in the 2020s when they are denied the right to bid on those future launches. And expect the Air Force to then back down, as it was forced to do when SpaceX was denied the right to bid on Air Force contracts early in this decade.
One more thought: This protest suggests Blue Origin already expects to not get picked. This expectation might also explain why Jeff Bezos decided to sell more Amazon stock last week, raising almost $3 billion in capital. He might be anticipating that Blue Origin will be cut out of those Air Force contracts, and so needs more of his own money to develop its New Glenn rocket.
You heard it hear first! The European Space Agency (ESA) today confirmed earlier stories from last week that the parachutes for its ExoMars 2020 spacecraft had failed during a high altitude drop test on August 5.
I reported this on Saturday, August 10, noting that ESA had not confirmed it. It apparently took them a week to write the press release.
This was the second consecutive test failure for these parachutes, as noted in the release.
On 28 May this year, the deployment sequence of all four parachutes was tested for the first time from a height of 29 km – released from a stratospheric helium balloon. While the deployment mechanisms activated correctly, and the overall sequence was completed, both main parachute canopies suffered damage.
Following hardware inspection, adaptations were implemented to the design of the parachutes and bags ready for the next high-altitude test, which was conducted on 5 August, this time just focusing on the larger, 35 m diameter, parachute.
Preliminary assessment shows that the initial steps were completed correctly, however damages to the canopy were observed prior to inflation, similar to the previous test. As a result, the test module descended under the drag of the pilot chute alone.
The tests occur at high altitude where the Earth’s atmosphere mimics the thin atmosphere of Mars. In both cases it appears the parachutes became damaged very early in their deployment process, possibly during deployment. This means there might be a design problem with the deployment process. It also means that both tests were unable to test the chutes themselves, as they were damaged before inflation, meaning that the engineers still do not know if they would work as intended once filled with air.
All this puts incredible time pressure on the mission, which needs to launch in the summer of 2020 to meet its launch window. There is very little time to redesign and retest these chutes. I would rate their chances of meeting that launch date as less than 50-50.
Be prepared for bad news: While protesters against a new Chinese law in Hong Kong have shut the airport down, the Chinese government has begun to bring its military into the downtown area.
The initial cause of these protests is an attempt by China to impose a new extradition law on Hong Kong that would allow them to extradite people from Hong Kong into mainland China.
The changes will allow for extradition requests from authorities in mainland China, Taiwan and Macau for suspects accused of criminal wrongdoings, such as murder and rape. The requests will then be decided on a case-by-case basis.
Several commercial offenses such as tax evasion have been removed from the list of extraditable offenses amid concerns from the business community. Hong Kong officials have said Hong Kong courts will have the final say whether to grant such extradition requests, and suspects accused of political and religious crimes will not be extradited.
The government has sought to reassure the public with some concessions, including promising to only hand over fugitives for offenses carrying maximum sentences of at least seven years.
It appears that the population in Hong Kong does not trust the Chinese government that has ruled them since the British left in 1999. They fear the misuse of this law in order to arrest anyone the Chinese government doesn’t like.
The question is whether the Chinese can do in Hong Kong what they did in Tiananmen Square in 1989. Then the government moved the military in and massacred the protesters, effectively ending any political opposition to communist rule. If they do this in Hong Kong they will also end the lingering freedom in that city left over from British rule..
