Local Texas city council votes to keep spaceport
The Midland, Texas city council today voted to renew its contract with the company managing its spaceport there.
The council voted 6-1 to renew its contract with SilverWing Enterprises, an aerospace consulting company that manages Midland’s spaceport license. The one vote came from Spencer Robnett, who has been public with his belief that the spaceport needs to be shut down.
“Yeah I don’t think it would ever have a chance in Midland,” Robnett said. “I do think the space business and space technology and aerospace sector is evolving. There’s a lot of money being invested in it by billionaires, Bezos, Musk, and Branson. Unfortunately we don’t have a billionaire in Midland chasing aerospace investment. We’ve got a small economic development corporation that takes direction from the city council.”
Robnett might have a point. Midland’s spaceport had been the base of operations for XCOR’s Lynx, and with XCOR bankrupt and gone there doesn’t seem to be a lot of interest by anyone else in flying any rockets from there. Part of their problem is their location, which is far from the coast and would likely limit the launch options in order to avoid populated areas.
The question has to be: What does Midland offer to rocket companies that other spaceports don’t? Until they can provide an answer to that question, the money the council is spending on this spaceport is probably going to waste.
NASA extends Chandra telescope operation to 2024
NASA has extended its contract with the Smithsonian Astrophysical Observatory in Massachusetts to run the Chandra X-ray Observatory through 2024.
In many ways the longevity of both Hubble and Chandra as well as other space telescopes has demonstrated the robustness of much in-space engineering these days. It suggests that when we finally begin building manned interplanetary spaceships we should have confidence they will operate reliably for long periods.
SpaceX gets contract to launch private lunar rover missions
Capitalism in space: SpaceX has won a contract for two launches of lunar rovers built by a private Japanese company.
Tokyo-based lunar-exploration startup Ispace has signed up for launches on SpaceX’s Falcon 9 rocket in 2020 and 2021. The first will carry a lunar lander into orbit around the moon, and the second aims to put one on the moon’s surface so it can deploy a pair of rovers, Ispace said Wednesday. “We share the vision with SpaceX of enabling humans to live in space, so we’re very glad they will join us in this first step of our journey,” Ispace Chief Executive Officer Takeshi Hakamada said in a statement.
SpaceX already has a contract for another private lunar rover, built by the Israeli company SpaceIL, that is set to launch as a secondary payload in December.
Both companies are former competitors in the Google Lunar X-Prize competition. Based on these contracts, as well as the pending launch of Moon Express’s private lunar rover on a Rocket Lab Electron rocket, it appears that private commercial planetary missions are about to become routine.
China schedules deorbit of Tiangong-2 station for July 2019
Assuming nothing goes wrong beforehand, China has now scheduled the deorbit of its Tiangong-2 test space station module for July 2019.
This decision is not surprising. They want to keep the station aloft and operating as long as possible to test its design and how that engineering can be applied to their full sized station planned for the 2020s.
Ariane 5 launches two communication satellites

25 China
16 SpaceX
8 Russia
7 ULA
6 Europe (Arianespace)
China remains ahead of the U.S. 25 to 24 in the national rankings.
Millennials are staying married; thus divorce rate plummets
Good news the future’s children! New data shows that millennials are returning to more traditional marriage patterns, staying married longer and thus causing the divorce rate to plummet.
New data show younger couples are approaching relationships very differently from baby boomers, who married young, divorced, remarried and so on. Generation X and especially millennials are being pickier about who they marry, tying the knot at older ages when education, careers and finances are on track. The result is a U.S. divorce rate that dropped 18 percent from 2008 to 2016, according to an analysis by University of Maryland sociology professor Philip Cohen.
…the divorce rate’s decline isn’t a reflection of a decline in marriages. Rather, it’s evidence that marriages today have a greater chance of lasting than marriages did ten years ago. “The change among young people is particularly striking,” Susan Brown, a sociology professor at Bowling Green State University, said of Cohen’s results. “The characteristics of young married couples today signal a sustained decline [in divorce rates] in the coming years.”
The news is not all good. The drop in the divorce rate is partly there because of the non-stop behavior of baby boomers to get divorced, repeatedly. Their behavior warps the stats, and makes a mediocre marriage stat by Millennials appear better than it is. Nonetheless, the change in behavior between these two generations is a very good sign. And it will be an especially good thing for the innocent children that result from these more stable marriages, which in turn will be better for society as a whole. One of the reasons American culture has become more crude and unstable in the past few decades is strongly linked to the raising of children in broken homes. Give children a stable home and numerous studies have found they will grow up more stable and mature, and thus help make society itself more stable.

Mars Reconnaissance Orbiter spots Opportunity through dust
Mars Reconnaissance Orbiter has taken a picture through the fading Martian dust storm that spots Opportunity about halfway down Perseverance Valley in the rim of Endeavour Crater.
Engineers have been increasing the number of times per day they are attempting to communicate with the rover, so far all to no avail. The picture thus only really tells us that the storm is lifting and that MRO’s high resolution camera is operating normally after three months of limited picture taking because of the dust storm.
Australian agency pushes Australia to join NASA Gateway project
The new colonial movement: An Australian government agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), has put forth a space roadmap for that nation that includes a push for them to participate in NASA’s lunar orbiting Gateway project.
“And when you look at a moon base, the support systems of oxygen, water, food – and the general support systems around it – is something that nobody has ever done before,” he said. “When we looked around Australia, these are areas where Australia has as much skill as anyone else. Things like dry farming capabilities, remote mining capability, the fact that CSIRO perfected the titanium dust that you can 3-D print from … there are a whole range of things where we can potentially contribute.” It is an interesting fact that Australia has exceptional expertise in 3D printing titanium. This is even more interesting when you consider that on the moon – according to Dave Williams – there is an oxide that is very similar to titanium that could be reduced to a titanium dust, with oxygen as a by-product.
“Realistically, NASA will lead the whole thing. But they will be looking for partners, and the idea will be to identify which niche areas Australia should try to push its industry into, and try to get support for and to make it work,” he said.
Essentially, they are proposing that Australia get in on the Gateway boondoggle by focusing on and then offering to provide peripheral support services.
Much of this is bureaucratic twaddle, not to be taken too seriously. At the same time, it does outline for Australia areas where there are needs, and where their private space companies could make money.
Has Aerojet Rocketdyne lost engine race with Blue Origin?
Aerojet Rocketdyne financial documents suggest that it has given up the bidding competition with Blue Origin to supply a rocket engine for ULA’s Vulcan rocket.
The latest financial release from aerospace manufacturer Aerojet Rocketdyne reveals that the company spent none of its own money on development of the AR1 rocket engine this spring. Moreover, the quarterly 10-Q filing that covers financial data through June 30, 2018 indicates that Aerojet may permanently stop funding the engine with its own money altogether—a sign the company has no immediate customers.
Although Aerojet will continue to receive some funding from the US military through next year to develop its large, new rocket engine, this money won’t be enough to bring it to completion. Instead of having a flight-ready engine for use by the end of 2019, the filing indicates that Aerojet now intends to have just a single prototype completed within the time frame.
Essentially this means ULA will have no choice but to pick Blue Origin’s engine, unless the Air Force pulls its weight and demands it take Aerojet rocketdyne, even if that means a significant delay before Vulcan can launch.
Four candidate stars identified as home for Oumuamua
The uncertainty of science: Astronomers have identified four stars as possible home stars for the interstellar object Oumuamua.
Bailer-Jones and his colleagues found four stars that are possible candidates for ‘Oumuamua’s home world. All four of them are dwarf stars. The one that came closest to ‘Oumuamua, at least about one million year ago, is the reddish dwarf star HIP 3757. It approached within about 1.96 light-years. Given the uncertainties unaccounted for in this reconstruction, that is close enough for ‘Oumuamua to have originated from its planetary system (if the star has one). However, the comparatively large relative speed (around 25 km/s) makes it less probable for this to be ‘Oumuamua’s home.
The next candidate, HD 292249, is similar to our Sun, was a little bit less close to the object’s trajectory 3.8 million years ago, but with a smaller relative speed of 10 km/s. The two additional candidates met ‘Oumuamua 1.1 and 6.3 million years ago, respectively, at intermediate speeds and distances. These stars have been previously catalogued by other surveys, but little is known about them.
There is much uncertainty here. None of these stars might be Oumuamua’s actual original star, but might have instead shifted its orbit from its past course.
