NASA engineers today successfully completed the expansion of the Bigelow BEAM test module on ISS.
SpaceX has released a high speed version of the camera view taken from the camera mounted on the Falcon 9 first stage that successfully landed on a barge on Friday.
I have embedded that video below the fold. Quite entertaining, though it emphasizes how much the flight resembles a high speed roller coaster ride.

According to one press report tonight, Russia has successfully tested a new anti-satellite missile designed to destroy orbiting satellites.
There are a lot of unknowns here, including the fact that the report provides little information, including any data to explain how they know that it is an anti-satellite missile.
The competition heats up: As part of its XS-1 spaceplane development program DARPA this week put out a request for proposals for companies to build an experimental space plane capable of launching 10 times in 10 days for a cost of no more than $5 million.
NASA will try again on Saturday to expand the privately built BEAM module on ISS.
They think the reason the module didn’t inflate as planned the first time is because it has been packed ready for launch for more than fifteen months, ten months longer than originally planned.
That extra time in a tight squeeze might explain why the first inflation attempt didn’t go as planned. BEAM’s Kevlar-like fabric “layers have a memory to them,” Lisa Kauke, BEAM deputy program manager at Bigelow Aerospace, said during today’s teleconference. “The longer they’re packed, the more they’re compressed, and then it takes a little while for the shape to return.” This interpretation is bolstered by the fact that BEAM continued to expand overnight Thursday into Friday morning, even though no more air was being pumped in, Crusan said.
The competition heats up: Rocket Lab has successfully tested the second stage engine of its Electron rocket.
They are aiming for their first commercial launch in 2017.
Virgin Atlantic’s first-ever Boeing 747 jumbo jet has been listed for sale on eBay with a starting bid of more than a quarter million dollars and a ‘buy it now’ price of $900,000 (£615,000). The retired double-decker plane, called Lady Penelope, was taken out of service last year and is gathering dust at an aircraft boneyard, but it could see new life as a hotel or restaurant, depending on the buyer’s intentions.
Here is the ebay listing.
Sadly, it can no longer fly as its engines have been removed. You will have to take it apart and ship it yourself.
SpaceX is beginning to make the landings of its Falcon 9 first stage routine. They just successfully landed another first stage on their drone ship, even though this was once again a difficult geosynchronous satellite launch with high speeds and limited available fuel.
It also appears that they will also successfully place the commercial satellite in orbit.
Rosetta’s scientists have detected the amino acid glycine as well as other organic molecules in the atmosphere of Comet 67P/C-G.
Glycine is very hard to detect due to its non-reactive nature: it sublimates at slightly below 150°C, meaning that little is released as gas from the comet’s surface or subsurface due to its cold temperatures. “We see a strong correlation of glycine to dust, suggesting that it is probably released from the grains’ icy mantles once they have warmed up in the coma, perhaps together with other volatiles,” says Altwegg. At the same time, the researchers also detected the organic molecules methylamine and ethylamine, which are precursors to forming glycine. Unlike other amino acids, glycine is the only one that has been shown to be able to form without liquid water. “The simultaneous presence of methylamine and ethylamine, and the correlation between dust and glycine, also hints at how the glycine was formed”, says Altwegg.
The New Horizons science team has released the highest resolution image across Pluto’s face, taken by the spacecraft during its flyby last year.
This mosaic strip, extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14, 2015, now includes all of the highest-resolution images taken by the NASA probe. With a resolution of about 260 feet (80 meters) per pixel, the mosaic affords New Horizons scientists and the public the best opportunity to examine the fine details of the various types of terrain the mosaic covers, and determine the processes that formed and shaped them.
The view extends from the “limb” of Pluto at the top of the strip, almost to the “terminator” (or day/night line) in the southeast of the encounter hemisphere, seen at the bottom of the strip. The width of the strip ranges from more than 55 miles (90 kilometers) at its northern end to about 45 miles (75 kilometers) at its southern end. The perspective changes greatly along the strip: at its northern end, the view looks out horizontally across the surface, while at its southern end, the view looks straight down onto the surface.
Go to the full image, go to its top, center your browser on the image, and then pan down slowly to see it in all its glory. The image above is cropped from about two-thirds of the way down, about when the terrain is transitioning from what they call cellular nitrogen ice plains to pitted non-cellular nitrogen ice plains. It includes what looks like a cluster of cave pits on the left.
They have also provided a video which does the same as panning down yourself, but adds a scale and labeling.
After a five year journey the Jupiter science probe Juno today entered the gas giant’s gravity well.
It will fire its engines on July 4 to enter orbit.
The competition heats up: Blue Origin has completed construction of one of two new test cells for the development of its BE-4 rocket engine, only seven months after the company made the decision to build them.
Microsoft and Facebook have announced plans to lay a trans-Atlantic communications cable from Virginia to Spain.
Running from Virginia Beach, Virgina to Bilbao, Spain, MAREA (which is Spanish for “tide”), it will be the first cable to connect the US to southern Europe, over a distance of 6,600 km (4,100 miles). From Blibao, it will connect to network hubs in Europe, Africa, the Middle East and Asia, with the goal of improving speed and reliability. For Microsoft this means improvements for users of its cloud services, such as Bing, Office 365, Skype, Xbox Live, and Microsoft Azure, while for Facebook it means improvements for users of its eponymous social network.
I find this story very puzzling. The whole reason communication satellites exist is because they have historically been far cheaper to build and launch with far greater capacity than ocean cables. Thus, the decision of these companies to go with an undersea cable instead of satellites suggests that something has changed in that equation, though I can’t see what. Have undersea cables improved so much that they have a bigger capacity than satellites, so much bigger that it compensates for the higher cost of installation and maintenance?
The competition heats up: The next Chinese lunar probe will be an unmanned sample return mission
They hope to fly it in the second half of 2017.
The competition heats up: The next New Shepard test flight will try to land the capsule with only two of three parachutes.
No date for the flight was announced.
The competition heats up: Planetary Resources, the company that claims its goal is to mine asteroids, has raised $21 million to build and launch an Earth resources satellite.
They plan to create a 10-satellite constellation to provide this data commercially.
While everything this company is doing will eventually make asteroid mining easier and more effective, nothing they are doing now has anything to do with mining asteroids. Their first project was to build a prototype orbiting telescope to look for asteroids. This second project will sell data about the Earth.
Engineers called a halt today to the expansion of Bigelow’s BEAM module on ISS when the procedure did not go as planned.
Originally, the plan was to use air from tanks located inside BEAM to inflate these bladders, however analysis showed that this could cause expansion to occur too fast and potentially place damagingly high loads on the ISS in the process, so instead the air will be supplied from the station in a more controlled manner. It was not actually known precisely how the inflation dynamics would occur, as it has only ever been done twice before (Genesis I and II), neither of which were viewable from external cameras such as those found on the ISS.
This proved to be a learning curve, as after two hours of adding a few seconds of air into the module, only the width expanded, as opposed to the length. Mission controllers decided it would be best to defer operations for the day to allow them to evaluate the next steps.
An evening pause: The same people who gave us the Marble Machine show us again how to use technology to make good music.
Hat tip Danae.
The 30-second static fire engine test of the Antares first stage and new Russian engine has now been scheduled for May 31.
The window for the engine test, or hot fire, is 5 p.m. to 8:15 p.m. EDT. Backup test dates run through June 5. Completion of the test will be noted on the Wallops’ Facebook and Twitter sites. During the test, the upgraded Antares dual RD-181 rocket engines will fire for 30 seconds at maximum 100% power (thrust) while the first stage of the test rocket will be held down on the pad. The hot fire will demonstrate the readiness of the rocket’s first stage and the launch pad fueling systems to support upcoming flights.
If all goes well, they hope to launch Antares with a Cygnus capsule in early July.
The European Southern Observatory today signed the contract to begin building the European Extremely Large Telescope (E-ELT).
The contract covers the design, manufacture, transport, construction, on-site assembly and verification of the dome and telescope structure. With an approximate value of 400 million euros, it is the largest contract ever awarded by ESO and the largest contract ever in ground-based astronomy. The E-ELT dome and telescope structure will take telescope engineering into new territory. The contract includes not only the enormous 85-metre-diameter rotating dome, with a total mass of around 5000 tonnes, but also the telescope mounting and tube structure, with a total moving mass of more than 3000 tonnes. Both of these structures are by far the largest ever built for an optical/infrared telescope and dwarf all existing ones. The dome is almost 80 metres high and its footprint is comparable in area to a football pitch.
The E-ELT is being built on Cerro Armazones, a 3000-metre peak about 20 kilometres from ESO’s Paranal Observatory. The access road and leveling of the summit have already been completed and work on the dome is expected to start on site in 2017.
E-ELT will have a main mirror 39 meters in width, about 9 meters bigger than the stalled TMT project.
The competition heats up: Orbital ATK today revealed plans to build what it calls the Next Generation Launcher designed to compete with SpaceX’s Falcon 9.
The first stage would use a variation of the solid rocket boosters that ATK built for the space shuttle. The second stage would be bought from Blue Origin.
The competition heats up: Iridium has announced the availability of its own location technology comparable to GPS and using the company’s constellation of satellites.
Iridium Communications Inc. has introduced its Satellite Time and Location (STL) service, an alternative or complement to traditional indoor and outdoor location-based technologies, and declared it ready for use. STL’s position, navigation and timing (PNT) technology is deployed through Iridium’s 66 cross-linked, low-earth orbit satellite constellation. Through Iridium satellites and in GNSS receivers, STL technology can work to verify GPS, GLONASS, Galileo and other navigation services, and also can serve as an alternative for those services when GPS signals are degraded or unavailable. STL also can provide an alternative source of time when testing GPS signals.
Essentially, for practically nothing, using satellites and technology already in orbit, they have created their own system that can both compete and complement the expensive government-built GPS systems.
The House appropriations committee has outlined its recommendations for NASA’s 2017 budget.
Like the Senate the House is pushing more money for SLS and is demanding NASA use it to fly two missions to Europa in the early 2020s (likely delaying SLS’s first manned mission), In addition, the House wants NASA to abandon any plans for an asteroid mission and instead go back to the Moon. They also pumped up the planetary program, and express reservations about the manned commercial program.
Finally, in a wonderful example of congressional micro-managing, the committee ordered NASA to begin work on flying an interstellar mission to Alpha Centauri by the 100th anniversary of Apollo 11.
While some of the changes the committee is recommending (increasing planetary research funding for example) make sense, the overall priorities of Congress continue to appear to me to be misplaced. Their continuing emphasis on SLS while questioning commercial space illustrates their focus on pork rather than actual accomplishments. And their continuing effort to micromanage many NASA missions does not bode well for the success of those missions.
There is one takeaway from this House budget recommendation that most news sources are missing: The first manned flight of Orion is almost certainly not flying in 2021. I have seen numerous indicators in the past four months suggesting that NASA is going to delay it, and this budget recommendation’s insistence that NASA use SLS to fly Europa missions in 2022 and 2024 almost guarantees that delay.
Cool image time! The New Horizons science team has released an image taken during the spacecraft’s fly-by of Pluto in July 2015 showing what they are calling “fretted terrain”.
The image above is a cropped reduced section of that image. It shows the strange transition zone between the higher elevation bright areas and the lower dark plains. As they note,
New Horizons scientists haven’t seen this type of terrain anywhere else on Pluto; in fact, it’s rare terrain across the solar system – the only other well-known example of such being Noctis Labyrinthus on Mars. The distinct interconnected valley network was likely formed by extensional fracturing of Pluto’s surface. The valleys separating the blocks may then have been widened by movement of nitrogen ice glaciers, or flowing liquids, or possibly by ice sublimation at the block margins.
In other words, they really don’t know what is going on.
The competition heats up: The United Kingdom has cancelled its spaceport competition to chose one spaceport and instead has announced it will allow any one of the competing locations to operate if they can want and can meet some licensing requirements.
In other words, instead of the government dictating one location as the nation’s spaceport, it will allow different locations to compete for the space launch business.
The link has few details, though a closer look at subject of the British space effort can be found here.
The competition heats up: India this morning successfully completed a test flight of its first spaceplane engineering prototype.
After a 90sec burn, the booster delivered the RLV-TD to the proper altitude before separating from the prototype and destructively fall back to Earth in the Bay of Bengal. Meanwhile, the RLV-TD continued on, falling back into Earth’s atmosphere at hypersonic velocity. During this hypersonic test, the RLV-TD pitched its nose up relative to the horizon and direction of travel – just as the Space Shuttles did during atmospheric entry. This allowed engineers to gather valuable in-flight data surrounding the performance of the vehicle’s thermal protection system (600 heat-resistant tiles and a carbon-carbon nose), its aerodynamic characteristics during hypersonic flight, and inform the overall design of the eventual full-scale RLV.
The prototype was designed to test the flight characteristics of the spaceplane, not its landing capabilities. If all went as planned, it would have glided horizontally into the ocean, as if it was landing on a runway, but then sink.

The article provides a good review of what they’ve done so far, and what they plan to do, including some good pictures of the planned station.
The third flight of the Air Force’s X-37B fleet, and the second for the ship in orbit, has now reached one year.
No word yet on how long this flight will last, or when the other ship will take off again.
My heart be still! Airbus has announced that it is beginning assembly of the first Orion capsule service module.
Considering the cost to build about three Orion flight capsules, about $25 billion, one would think that would be enough to also build the capsule’s service module, especially since this is not cutting edge technology, having already been done with Apollo.
Not however when you are dealing with pork-laden government operations, where the customer, the taxpayer, is a good mark that you can suck for as much money as possible without any bad consequences. Make it sound cool and they will buy it, hook, line, and sinker!
The competition heats up: India’s space agency ISRO has scheduled the test flight of its half scale space plane prototype for May 23.
