Breakthrough Listen adds southern hemisphere telescope to extraterrestrial listening campaign

8:51 am

Breakthrough Listen has added the MeerKAT telescope in South Africa to its extraterrestrial listening campaign, thereby expanding the campaign to cover almost the entire sky.

Breakthrough Listen’s MeerKAT survey will examine a million individual stars – 1,000 times the number of targets in any previous search – in the quietest part of the radio spectrum, monitoring for signs of extraterrestrial technology. With the addition of MeerKAT’s observations to its existing surveys, Listen will operate 24 hours a day, seven days a week, in parallel with other surveys. “Collaborating with MeerKAT will significantly enhance the capabilities of Breakthrough Listen”, said Yuri Milner, founder of the Breakthrough Initiatives. “This is now a truly global project.”

Built and operated by the South African Radio Astronomy Observatory (SARAO), and inaugurated in July 2018, MeerKAT is a powerful array of 64 radio antennas in the remote Karoo Desert of South Africa. By partnering with SARAO, Breakthrough Listen gains access to one of the world’s premier observing facilities at radio wavelengths. Signals from the 64 dishes (each 13.5 meters in diameter) are combined electronically to yield an impressive combination of sensitivity, resolution and field of view on the sky. MeerKAT also serves as a precursor for the Square Kilometre Array, which will expand and enhance the current facility in the coming decades, eventually spanning a million square meters across South Africa and Australia to create by far the world’s largest radio telescope.

They have also widened their approach. They are not simply looking for intelligent radio communications, they are looking for any signs of technology.

“Kill Kavanaugh” now tops Twitter feeds

9:21 am

They’re coming for you next: “Kill Kavanaugh” now tops Twitter search feeds, requiring only the typing of a “k” to get it near the top of any search, with “ki” placing at the very top of the search list.

Although many current tweets on the hashtag are critical of both the hashtag and Twitter’s double standards, earlier tweets use the hashtag unironically and uncritically. Several of these tweets have not been removed by Twitter, and the accounts that tweeted them do not appear to have been punished by Twitter in any way, despite the fact that some users say they have reported them.

It can be argued that some — but not all — of these tweets are metaphorical, calling for the nomination to be “killed” rather than the person, in the same way that a piece of legislation might be metaphorically “killed.” But refusing to take action against those tweets would still be an example of Twitter’s double standards: the platform has in the past permanently banned free speech maximalist users when they employed similar metaphors, using the least charitable interpretation of their remarks. This is the website that has silenced James Woods for tweeting a meme about soy boys that Jack Dorsey and his San Francisco menagerie argue could “impact an election.”

Twitter in general is a sewer of vicious hate and childish emotions, but that its management is willing to tolerate this kind of behavior from the left indicates they really support it.

The left, and the Democrats, are out for full and unopposed power, and they are willing to destroy anyone they perceive as getting in their way. Unfortunately, they have quislings like Senator Jeff Flake (R-Arizona) helping them. The man would have built the gas chambers for the NAZIS if they had asked him.

Occator Crater on Ceres

9:14 am

Occator Crater

Cool image time! As Dawn’s long and successful mission to the asteroids Vesta and Ceres winds down, the spacecraft is taking a slew of spectacular close-up images of Ceres. The image on the right, cropped slightly to post here, is an oblique view of Occator Crater, home to the double bright spots that scientists now believe are caused by the upward seepage of a water-based brine from the interior.

The image was taken August 14, 2018 from a distance of 1149 miles. It clearly shows how the bright spots are depressions, not raised features. Additional images released this week of the floor of the crater capture a complex fracture network (seen here and here) with some fractures apparently quite deep.

All this suggests that the surface crust of Ceres is not very structurally strong, allowing a churning process that plows material up and down. The data also suggests that even on a small planetary body like Ceres the geological processes are going to be complex and often on-going, depending on material, energy, and the size of the body.

Russia and China sign agreement for future space cooperation

8:56 am

The new colonial movement: Russia and China last week signed an agreement to establish a greater cooperation in future space projects.

“The session ended with the signing of a protocol in which the two parties agreed to take further steps to seek rapprochement in implementing joint projects for the manufacture of space vehicles and rocket engines, exploring the Moon and deep space, remote sensing of the Earth, satellite navigation, creating a base of electronics components for the space industry, and low orbit mobile communication systems and space debris monitoring,” the report runs.

This is a direct negotiating threat from Russia to the U.S., telling us that they might switch teams from NASA to China if they don’t get what they want in the Gateway partnership. And since NASA really doesn’t have the ability to build much itself (more on this later today), if they make this switch it could very well kill Gateway, all by itself.

Because of this, expect NASA management (part of the DC culture) to backstab the U.S. in any negotiations with Russia on Gateway. Rather than defend U.S. interests, they will instead be focused on guaranteeing Russia participation, even if the deal might cripple the burgeoning private American space industry.

Three U.S. small space companies establish offices in Luxembourg

7:48 pm

Capitalism in space: Three U.S. small space companies have now established offices in Luxembourg in order to take advantage of the financial backing that nation is willing to afford.

The government of Luxembourg announced Sept. 27 that CubeRover, Hydrosat and Made In Space will all establish facilities in the country, in many cases working with local universities and companies. The work those companies do in Luxembourg will range from development of robotic arms to small planetary rovers.

“The success of our development strategy for the space sector, including the recent launch of the Luxembourg Space Agency, is confirmed once more with the settlement in Luxembourg of three space companies that plan to employ up to 85 people in the Grand-Duchy by 2023,” said Étienne Schneider, deputy prime minister and minister of the economy of the Luxembourg government and the driving force for the country’s recent space initiatives.

The largest agreement, in terms of jobs created, goes to Made In Space. That company, best known for additive manufacturing work on the International Space Station, plans to work on a low-cost modular robotic arm for in-space applications, and will create up to 50 jobs in the country.

They did not mention what the terms are of Luxembourg’s financial support, but I suspect it is most helpful for these companies.

Musk settles with SEC, pays fine, reduces control at Tesla for 3 years

7:43 pm

Elon Musk and Tesla have negotiated a settlement with the SEC, agreeing to each pay a fine of $20 million while Musk reduces his role with the company for the next three years.

Musk and Palo Alto-based Tesla agreed to pay a total of $40 million to settle the case, and he will give up his chairmanship for at least three years. The electric-car maker also is required to install an independent chairman and two new board members, though Musk will remain on the board, according to terms of the settlement.

Musk and Tesla will each pay $20 million to settle the case; both reached the deal without admitting wrongdoing.

I suspect this will not reduce Musk’s influence on Tesla very much. To me, this whole kerfuffle was the SEC acting like a bunch of mobsters, pulling its weight against someone it apparently doesn’t like. “Nice business you have there, Elon. Sure would be a shame if something happened to it.”

UAE astronaut flight to ISS tentatively scheduled for April

7:28 am

Russia has now tentatively scheduled the flight to ISS of the United Arab Emirates first astronaut.

The first astronaut from the United Arab Emirates (UAE) will fly to the International Space Station (ISS) on April 5, 2019, and will return to Earth on April 16, 2019, the ISS launch schedule, shared with Sputnik, has shown. According to the document, an astronaut will fly to the ISS on board the Russian Soyuz MS-12 spacecraft.

It has not been determined yet if Hazza Mansouri or Sultan Nayadi will take part in the mission. Both astronauts have qualified for it and have begun their training in Russia earlier in September.

Though the goal of this mission by the UAE government is to encourage a private space industry in their country, the mission remains wholly a government creature. What has not been released is how much UAE is paying the Russians for their flight.

Had the launch of the U.S. commercial crew spacecraft not been slowed by NASA and had been operational, either SpaceX or Boeing could have competed for this business. Expect them to do so in the future.

China launches smallsat

7:10 am

One of China’s claimed-to-be private companies, Expace, today launched a smallsat into orbit using the Kuaizhou-1A solid-fueld rocket. .

Exspace, like OneSpace and Ispace, is considered private by the Chinese. I find it interesting however that all these private companies have remarkably similar names, and all appear to be doing military work. Even if they get private financing from Chinese investors and their management is formed independent of the government, we should not be fooled. These are wholly owned and controlled by the Chinese government. They do nothing without its knowledge and support.

The leaders in the 2018 launch race:

26 China
16 SpaceX
8 Russia
7 ULA
6 Europe (Arianespace)

China has widened its lead over the U.S. in the national rankings, 26 to 24.

Stratolaunch building its own rocket engine

7:35 am

Capitalism in space: Stratolaunch yesterday revealed details about its PGA rocket engine that it is developing in house.

The hydrogen-fueled PGA will produce 200,000 pounds of liftoff thrust. “When you try to do something like single stage to orbit, or in our case air launch, you really have to have hydrogen performance to make it happen,” Jeff Thornburg, Stratolaunch’s vice president of propulsion engineering, told Aviation Week.

Stratolaunch says that 85 percent of the manufacturing process will take advantage of additive-manufacturing techniques, also known as 3-D printing. That’s aimed at reducing the cost of engine production. “The propulsion team is currently in the process of manufacturing and testing prototype subscale and full-scale hardware,” Stratolaunch says. “The team has completed ignitor development, with injector testing currently underway. After this is completed, the team will perform a full-scale preburner test by the end of 2018.”

The engine is being designed to power the rockets and manned ferry that they also plan to build to be launched from the bottom of their giant airplane Roc.

It is clear now that they could not find anyone else willing to build these upper stages, and are now building them themselves. This means that SpaceX, with its Big Falcon Rocket, is now not the only company building a completely reusable system for gaining access to space.

Roscosmos head meets with Chinese

7:25 am

The head of Russia’s Roscosmos space agency, Dmitry Rogozin, held meetings this week with China, discussing possible future space cooperation.

Russia can’t really afford to do much right now on its own, but it also wants to negotiate the best deal it can with anyone it works with in space. These discussions are therefore specifically designed to give Rogozin some negotiating leverage when he meets with NASA’s head Jim Bridenstine on October 10.

New images from Hayabusa-2’s mini-bouncers

7:17 am

Three press releases from the Hayabusa-2 science team last night provide new images from the spacecraft’s MINERVA bouncers, presently on the surface of Ryugu, as well as new high resolution images from Hayabusa-2 during its recent close-in maneuvers.

The images from the first story also includes a ten second movie showing a very rocky surface with the sun moving across the sky. The last link shows the primary landing site candidate with two backup sites.

All told, these images suggest that Ryugu is nothing more than a rubble pile stuck together. If it was heading to Earth, it might be difficult to deflect it, as it might break apart caused by any stress.

Next Long March 5 launch delayed again?

10:18 pm

There are indications in the Chinese press that suggest the next launch of China’s largest rocket, the Long March 5, will be delayed from its present November launch into 2019.

An online report by People’s Liberation Army Daily, a military newspaper, reports Lin Xiqiang, deputy director of the China Manned Space Engineering Office (CMSEO), as saying at a press conference in Beijing on Wednesday that the Long March 5B will not make its planned test launch in the first half of 2019.

“Due to the failure of the launch of the Long March 5 remote launch vehicle, the first flight of the Long March 5B carrier rocket will be postponed. The specific implementation time needs to be clarified after coordination with relevant departments,” Xiqiang said.

The November launch was to put up a test communications satellite. Should it slip into 2019, this would likely also cause delays in the launch of China’s first lunar sample return mission, Chang’e-5 (originally scheduled for 2017), the launch of China’s first Mars planetary mission in 2020, and finally the launch of the first module of China’s space station, also set for 2020.

All this once again indicates that the problems with Long March 5 were very serious, and might not yet have been addressed, even with a redesign of its engines.

SEC goes after Musk

8:02 pm

The Securities and Exchange Commission today filed a complaint against Tesla in an effort to force Elon Musk out as head of the company.

The complaint filed by the Securities and Exchange Commission came after a last-minute decision by Mr. Musk and his lawyers to fight the case rather than settle the charges.

The filing by the SEC in federal court in Manhattan threatens to deal a severe blow to the Palo Alto, Calif., electric car maker. Its brand and Mr. Musk are closely intertwined, and analysts have said the company’s roughly $50 billion market value is driven by Wall Street’s appreciation for Mr. Musk’s vision and skill as an innovator.
SEC Sues Elon Musk for Fraud, Seeks Removal From Tesla

Tesla wasn’t named in the suit as a defendant, but the SEC is seeking to bar Mr. Musk, Tesla’s largest shareholder and its top executive, from serving as an officer or director of any U.S. public company. Tesla shares, which have been under intense pressure amid questions about the firm’s financial strength and Mr. Musk’s behavior, tumbled 9.9% to $277 in after-hours trading Thursday on Nasdaq.

This is very bad news for Tesla. However, it might be good news for SpaceX, as Musk has admitted to being very overworked. If he is forced from Tesla, he will have an enormous load removed from him.

ULA picks Blue Origin rocket engine for Vulcan first stage

3:38 pm

Capitalism in space: ULA has chosen Blue Origin’s BE-4 rocket engine to power the first stage of its next generation rocket, which they are now calling Vulcan-Centaur.

Two BE-4 engines will be used to power the Vulcan first stage. The press release does not mention anything about how they plan to recover these first stages. Earlier announcements had said that they would separate from the rocket stage and parachute down to be capture before hitting the ground.

Local Texas city council votes to keep spaceport

4:03 pm

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

8:02 am

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

7:52 am

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.

Millennials are staying married; thus divorce rate plummets

9:08 pm

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

3:41 pm

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

3:32 pm

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?

2:59 pm

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

8:14 am

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.

Dust storms spotted on Titan

7:44 pm

Scientists reviewing Cassini data have identified dust storms for the first time of Saturn’s moon Titan.

When Rodriguez and his team first spotted three unusual equatorial brightenings in infrared images taken by Cassini around the moon’s 2009 northern equinox, they thought they might be the same kind of methane clouds; however, an investigation revealed they were something completely different. “From what we know about cloud formation on Titan, we can say that such methane clouds in this area and in this time of the year are not physically possible,” said Rodriguez. “The convective methane clouds that can develop in this area and during this period of time would contain huge droplets and must be at a very high altitude — much higher than the 6 miles (10 kilometers) that modeling tells us the new features are located.”

The researchers were also able to rule out that the features were actually on the surface of Titan in the form of frozen methane rain or icy lavas. Such surface spots would have a different chemical signature and would remain visible for much longer than the bright features in this study, which were visible for only 11 hours to five weeks.

In addition, modeling showed that the features must be atmospheric but still close to the surface — most likely forming a very thin layer of tiny solid organic particles. Since they were located right over the dune fields around Titan’s equator, the only remaining explanation was that the spots were actually clouds of dust raised from the dunes.

Obviously there are large uncertainties here. Nonetheless, the conclusion is a reasonable one, as it is expected that such dust storms would occur on Titan.

Greenhouse in Antarctica survives winter for 1st time

8:22 am

A greenhouse in Antarctica that is partly maintained remotely from Germany has survived through the polar winter for the first time.

Regularly withstanding temperatures below minus 40 degrees Fahrenheit (minus 40 degrees Celsius), the greenhouse provided herbs, lettuce and other vegetables to 10 people who were riding out the winter in the remote station, called the Alfred Wegener Institute’s Neumayer Station III. It’s the first time the greenhouse operated through the winter. “After more than half a year of operation in Antarctica, the self-sufficient greenhouse concept appears to be effective for climatically demanding regions on Earth, as well as for future manned missions to the moon and Mars,” DLR officials said in the statement.

“The harvests are now so plentiful that some of it does not always make it straight to the table, and we now have the luxury of spreading out our consumption of some refrigerated lettuce and herbs over several days,” Paul Zabel, a DLR researcher who works with EDEN ISS, said in the statement. “The overwintering team members are always looking forward to their next fresh meal.”

From a space exploration perspective, the most interesting aspect of this story is that, when the weather was too hostile for its Antarctic maintainer to reach it, the greenhouse was then maintained remotely from Germany, for up to three consecutive days. Clearly hands-on maintenance is necessary for such a facility, but to design it so that remote maintenance can occur is a technical capability that space-colonists are definitely going to want to have.

Bill increases funding to FAA space office, adds other provisions

7:27 am

A bill about to be approved by Congress increases funding to the FAA Office of Commercial Transportation while also requiring that office to create several new regulatory positions.

The bill authorizes a significant increase in spending for the FAA’s Office of Commercial Space Transportation, or AST, from the $22.6 million it received in fiscal year 2018 to a little more than $33 million in 2019, growing to nearly $76 million in 2023. Appropriators, though, have not matched that authorized increase for 2019, with House and Senate versions of spending bills funding the FAA offering just under $25 million for AST.

The reauthorization bill includes several policy provisions associated with commercial spaceflight as well. One would require the FAA to designate an official within its air traffic organization to serve as the single point of contact for working with the head of AST on airspace issues associated with commercial launch activity.

Another provision establishes an “Office of Spaceports” within AST intended to support commercial licensing of launch sites and develop policies to promote infrastructure improvements at such facilities. It also requires AST to develop a report within one year of the bill’s enactment on spaceport policies, including recommendations on government actions to “support, encourage, promote, and facilitate greater investments in infrastructure at spaceports.” It directs the Government Accountability Office to prepare a separate report on ways to provide federal support for spaceports.

The bill creates a category of commercial spaceflight vehicles known as “space support vehicles” that cover parts of launch vehicles systems flying for other purposes, such as training or testing. Such vehicles would include the aircraft used by air-launch systems. The bill allows commercial flights of space support vehicles without the need for a full-fledged airworthiness certificate from the FAA.

It is hard to say if these provisions will help or hurt the growth of commercial space. It does appear that Congress’s goal was to help, but their methods always include more spending and greater bureaucracy.

The article also reviews a number of bills not yet agreed to by Congress that would address the regulation of Earth observation satellites as well as satellite servicing. It quotes a number of industry experts supporting the laws being proposed, but once again, it is unclear if those laws would help or hurt. My previous review of one of these laws presently working its way through the House was decidedly mixed. It will clarify and simplify many of the regulatory problems that presently exist, while creating more bureaucracy.

Japan successfully launches unmanned cargo ship to ISS

1:00 pm

Japan today used a Mitsubishi H-2B rocket to successfully launch an unmanned cargo ship to ISS.

The cargo ship will take five days to rendezvous and dock with ISS. Its most interesting piece of cargo is a small capsule with a heat shield, designed to return experiment samples to Earth.

JAXA says the the capsule has an internal volume of about 30 liters, and astronauts could load up to 44 pounds (20 kilograms) of specimens inside the landing craft, which features a thermos-like container to store refrigerated biological samples. That is a fraction of the carrying capacity of the Dragon capsule, but the new HTV Small Return Capsule will offer station managers a new way to make sure time-critical items can return to Earth for analysis.

Astronauts will assemble the return capsule after the HTV arrives at the station, and mount it into position over the HTV’s forward hatch for deployment once the supply ship leaves the station.

The capsule, which carries no engines of its own, will jettison after the HTV completes its deorbit burn. The re-entry craft will deploy a parachute and splash down in the Pacific Ocean, where recovery teams will retrieve it and bring it back to Japan for inspections.

The leaders in the 2018 launch race:

25 China
16 SpaceX
8 Russia
7 ULA
5 Europe (Arianespace)
5 Japan

For Japan to be tied with Europe this late in the year either indicates that Europe is sagging, or Japan is growing. I suspect it is partly both. In the national rankings China still leads the U.S. 25 to 24.
