Congress approves establishment of Space Force

9:26 am

In a deal where the Trump administration agreed to a Democratic Party demand that all military personnel be given twelve weeks of paid parental leave, Congress has approved the formation of a new branch of the military dubbed the U.S. Space Force.

In a Dec. 6 deal, the White House agreed to grant 12 weeks of paid parental leave to all federal workers in exchange for the Space Force authorization. The parental leave provision was a top priority for Democrats while the White House has been insistent that any deal should include language to authorize the Space Force.

The House is expected to vote on the compromise bill on Dec. 11. The Senate will take it up at a later date.

The NDAA provides the Secretary of the Air Force with the authority to transfer Air Force personnel to the newly established Space Force. But it does not approve the hiring of new people. The Air Force Space Command is redesignated as the U.S. Space Force. “To minimize cost and bureaucracy, the Space Force will require no additional billets and remains with the President’s budget request,” says the report. The request includes $72.4 million to stand up the headquarters. [emphasis mine]

It appears that initially the Space Force will operate under the auspices of the Air Force, but only during a transitional period.

The highlighted words suggest that Congress has managed, at least so far, in making this new agency mostly a rearrangement of personnel, something that makes sense. Military space operations need to be consolidated into one command structure.

We shall see however if Congress (and future presidents) can resist allowing this new bureaucracy to grow. I have my doubts, which if proven true will defeat the entire purpose for doing this. For example, while generally avoiding the hiring of many new people, the legislation also creates three new administrative posts, all of which I guarantee will eventually demand their own bureaucracies.

ESA hires private company to remove space junk

9:12 am

Capitalism in space: The European Space Agency has hired the private company ClearSpace to fly an unmanned mission aimed at de-orbiting a large no-longer-needed launch component of its Vega rocket.

The European Space Agency signed a debris-removal contract with Swiss startup ClearSpace tasking the company with deorbiting a substantial piece of a Vega rocket left in orbit in 2013.

The mission, dubbed ClearSpace-1, is slated to launch in 2025 to capture and deorbit a 100-kilogram Vespa payload adapter an Arianespace Vega left in orbit after deploying ESA’s Proba-V remote-sensing satellite.

ClearSpace will lead a consortium of European companies in building a spacecraft equipped with four robotic arms to capture debris and drag it into Earth’s atmosphere.

The real importance of this contract is its nature. ESA is not taking the lead in designing or building the robot to do this work. Instead, it is acting merely as a customer, hiring ClearSpace to develop and build it. Afterward the robot design will belong to ClearSpace, which will then be able to sell that design for further space junk removal contracts.

[Luc Piguet, co-founder and chief executive of ClearSpace] said that while this first mission will destroy both the debris and the servicer spacecraft, future plans call for servicers that could deorbit multiple objects without also destroying themselves.

It seems that the ESA is following the recommendations I put forth in Capitalism in space, shifting power and ownership of its space missions from the agency to the private sector. This is excellent news.

New Shepard test flight delayed to tomorrow

8:58 am

The sixth flight of Blue Origin’s second New Shepard reusable suborbital capsule has been delayed today until tomorrow due to weather.

As they have done on the last few flights they are launching a number of commercial payloads, including winning high school art chosen as part of a contest sponsored by both Blue Origin and the music band OK Go.

I have embedded below the fold the live stream for tomorrow’s launch, set to go live at around 8 am (Eastern).

The dark splotches on Mars: Magnets for dust devils

3:38 pm

Olympus Maculae, land of dark splotches

One of the numerous geological mysteries that planetary scientists have discovered among the many high resolution images taken by the various Martian orbiters are a series of dark splotches, ranging in diameter from one to fifteen miles, running in an east-west line on the lower western slopes of the giant volcano Olympus Mons.

Scientists have dubbed this string of splotches Olympus Maculae and, because of their superficial resemblance to the islands of Hawaii, have labeled each splotch, or macula, after those islands, as shown in the overview map above, created by geologist Kirby Runyon of the Applied Physics Lab in Maryland as part of a presentation [pdf] given at a science conference in September 2019.

Prior to the 2018 global dust storm on Mars scientists were not quite sure what caused these dark patches. The data suggested the maculae were less dusty than the surrounding terrain, but why this was so was not clear.

The advent of that storm however gave them a chance to get before and after photos. In October 2018 I found several images in monthly download of new images from the high resolution camera of Mars Reconnaissance Orbiter (MRO) and posted them, making a vain attempt to locate what had changed. As I wrote,

I found that MRO has taken images of this location twice before, in 2007 and in 2009. I spent about fifteen minutes trying to find something that had changed, but was unable to locate anything, other than what look like a few wind-blown streaks probably caused by dust devils. I suspect I do not know what to look for.

I then made some guesses about what caused these splotches, all wrong I have since learned.

Since then more images of these splotches have been downloaded from MRO, all once again indicating that changes have been detected. Below is a sequence of images of the splotch dubbed Ka’ula, the first taken in 2008, the second in 2018 just after the global dust storm, and the third in 2019, one year after the storm. Set side-by-side the changes are more obvious.

Dragon launch abort test set for January 4

11:41 pm

NASA announced on December 6 that the launch abort test of SpaceX’s crew Dragon capsule will occur no earlier than January 4.

SpaceX and NASA originally hoped to launch the test flight, called an In-Flight Abort Test, sometime this month, but an exact launch date was never released. In a statement Friday, NASA officials said the mission will now lift off no earlier than Jan. 4 from Pad 39A of NASA’s Kennedy Space Center in Cape Canaveral, Florida, pending launch range approval from the U.S. Air Force.

The new launch target will push the SpaceX flight beyond the year-end holidays, as well as a planned Boeing launch of its first uncrewed Starliner astronaut taxi for NASA, which is slated to launch Dec. 20.

The article does not explain why a December test was not possible. The second paragraph of the quote above however might give a hint, in that a December launch might have interfered with those Christmas/New Year holidays, and both the agency and the company might have decided it was better for all to wait an extra week or so.

ISRO officially requests funds for new lunar lander/rover

10:24 pm

The new colonial movement: India’s space agency ISRO has now officially requested funding to build a new lunar lander/rover, dubbed Chandrayaan-3, to launch as early as November 2020.

The TOI [Times of India], which was the first to report that Isro is looking to launch another Moon landing mission as early as next November, has now been able to get a confirmation from the department of economic affairs that the space agency has, in fact, sought Rs 75 crore [approximately $14 million] for Chandrayaan-3.

As per initial plans, Chandrayaan-3 will have a lander, a rover and a detachable propulsion module to carry fuel.

The money has been sought under the provisions of a supplementary budget for the present financial year. Of this, Rs 60 crore will be for “meeting expenditure towards machinery, equipment and other capital expenditure,” while the remaining Rs 15 crore is sought under revenue expenditure head.

The article also notes that ISRO “has already set up multiple committees to work on Chandrayaan-3.”

Two Chinese Kuaizhou-1A launches within six hours

9:20 am

The new colonial movement: China today successfully completed two separate Kuaizhou-1A launches, placing in orbit seven total smallsats and doing it within a space of only six hours.

China launched two orbital missions from the Taiyuan Satellite Launch Center within six hours of each other, orbiting a total of seven satellites. The launches, using mobile pads, saw two Kuaizhou-1A rockets heading into space on Saturday at 2:55 UTC and 8:52 UTC.

The first Kuaizhou-1A rocket, serial number Y2, orbited the Jilin-1 Gaofen-2B remote sensing satellite for the Jilin-1 constellation.

…Six hours after the first launch, and as was expected by the navigational warnings previously published, a second Kuaizhou-1A launch vehicle, serial number Y12, had already been displaced to the launch site, but from a different pad. Analysis of the images available from the second launch seems to indicate that launch took place from a location within the Launch Complex 16 usually used for the Long March-6 launches. Ignition came at 8:52UTC.

The three-stage launch vehicle orbited six satellites.

This achievement is a very big deal. China has demonstrated the ability to launch and then launch again quickly with this military-based mobile launch system. This not only enhances their commercial value, it tells us they have developed a military capability able to put payloads into orbit at almost a moment’s notice.

The leaders in the 2019 launch race:

29 China
19 Russia
12 SpaceX
7 Europe (Arianespace)
6 Rocket Lab

China now leads the U.S. 29 to 25 in the national rankings.

Cloud stream on Jupiter

Cloud stream on Jupiter
Click for full image.

Cool image time! The photo to the right, taken by Juno on November 3, was enhanced by citizen scientist Björn Jónsson to bring out the colors. It shows a band of repeating large storms, with tiny white thunderheads popping up within them.

The dark areas at the edges of the swirls are likely not an aspect of the clouds but shadows created because the white swirls sit higher than the surrounding gases.

Sadly the press release does not give us a scale. The image was taken from a distance of 3,200 miles. I suspect each cloud swirl would likely cover much of the Earth.

Inmarsat bought out and delisted from stock exchange

9:07 am

Capitalism in space: The long established communications satellite company Inmarsat has been bought out by a consortium called Connect Bidco and delisted from stock exchange.

Nor is Inmarsat alone:

Inmarsat is the third satellite operator to delist from public markets this year, following Hong Kong-based AsiaSat and London-based Avanti in September.

Inmarsat reported a loss of $89.1 million on $1.06 billion in revenue for the first nine months of the year. The company claimed $36.1 million in profits on $327.3 million in revenue for the months of July, August and September — it’s last public quarter before the buyout.

This story and the quote above explain what is happening. Established satellite companies, that traditionally have built big geosynchronous satellites, are having increased trouble making money as the industry shifts to smaller satellite and constellations in low Earth orbit.

Successful Russia and Rocket Lab launches

8:52 am

Two launches successfully took place in the early morning hours today. First Rocket Lab launched seven small satellites into orbit, including one that will release an artificial meteor shower. During that launch they also obtained telemetry of their first stage as it fell to Earth.

Rocket Lab CEO Peter Beck just tweeted that the Electron’s first stage performed well during today’s re-entry experiment. “Electron made it through wall! Solid telemetry all the way to sea level with a healthy stage. A massive step for recovery!!” Beck tweeted.

Russia in turn launched a Progress cargo capsule to ISS.

The leaders in the 2019 launch race:

27 China
19 Russia
12 SpaceX
7 Europe (Arianespace)
6 Rocket Lab

China now leads the U.S. 27 to 25 in the national rankings.

Lloyd’s introduces new insurance policy for smallsats

10:57 am

Capitalism in space: The insurance company Lloyd’s today introduced a new insurance policy expressly designed for the emerging smallsat launch industry.

The solution – called “Llift Space” – is only available in the Lloyd’s market and allows customers to cover their assets from the pre-launch phase, including transit and placement on the launch vehicle, through to the launch phase and in-orbit operation. It is designed for satellites that weigh less than 300 kilograms (661.4 pounds).

The policy is modular so customers can choose the elements within each phase that are most relevant to their coverage needs.

The product is backed by a consortium of 18 syndicates, led by Brit and Hiscox MGA, with $25 million capacity per risk, and is targeted at the NewSpace sector.

NewSpace is characterized by lower cost, easier routes to space, opening up the sector to private enterprise, wealthy entrepreneurs and innovative start-ups. This is increasing the need for space insurance.

This action is a strong endorsement by the investment business in the future of the new smallsat launch industry.
