Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.

The competition heats up: Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.

This is good, but there is something about the pace of development of the CST-100 that seems mighty slow to me. Last September there were indications that Boeing might shelve the project, which were countered in November by word that they were instead considering increasing their investment.

The slow pace suggests to me that management has rejected the latter. It also suggests that while they haven’t shelved the project, they are not pushing it hard, which means that eventually it will die because it will fail to compete with other more ambitious and competitive efforts.

The Alpha Magnetic Spectrometer on ISS has detected a surplus of positrons, anti-matter electrons, that physicists believe are caused by the existence of dark matter.

The Alpha Magnetic Spectrometer on ISS has detected a surplus of positrons, anti-matter electrons, that physicists believe are caused by the existence of dark matter.

The lead scientist of the experiment also emphasized that dark matter is not the only possible explanation, and that “The detailed interpretation of our data probably will have many theories.”

Sarah Brightman’s visit to ISS in doubt.

Sarah Brightman’s visit to ISS in doubt.

Soyuz taxi flights normally visit the International Space Station for a period of about eight days. NASA and Roscosmos are considering extending a 2015 visit to one month, however. If that happens, Brightman would have to give up her seat to a scientific researcher, who would perform some short-term experiments aboard the space station.

Roscosmos manned space flight director Alexei Krasnov had previously indicated that Russia might consider carrying two paying customers on the 2015 taxi flight. So, it would be theoretically possible for Russia to fly Brightman and the researcher. It’s unknown whether Brightman would want to spend that long aboard the space station, however, and pricing policy to longer-duration stays have not been worked out.

Dragon has been successfully berthed with ISS.

Dragon has successfully berthed with ISS.

The naysayers will focus on the thruster problems on Friday. The yaysayers will focus on the fix and berthing today. The bottom line, however, is that this mission once again proves that SpaceX is a real player in the space business. Every other company has to match its achievements, most especially in price. The result will be the eventually lowering in the cost to low Earth orbit, which will then make all things possible.

And in fact, we are already seeing this, with the appearance of many new private companies or organizations, proposing all sorts of new space efforts, such as mining asteroids or sending people to Mars. The lower cost allows dreamers to consider their wild new ideas more doable. And they then go ahead and try to do it.

SpaceX has announced that they now have all of Dragon’s thrusters operating and are go for docking with ISS.

SpaceX has announced that they now have all of Dragon’s thrusters operating and are go for docking with ISS.

They have not announced when the docking will occur, but with the solar panels operating the capsule can function in orbit for a considerable time, giving them breathing room. And time will be necessary as both NASA and the Russians are nervous about letting any spacecraft approach ISS and will want a good number of tests to make sure all is well. The Russians are especially nervous, since they had the unfortunate experience of several collisions when they operated their space station Mir.

Some more details have been revealed about Bigelow’s deal with NASA to send one of its modules to ISS.

Some more details have been revealed about Bigelow’s deal with NASA to send one of its modules to ISS.

This is apparently going to be another test of a smaller prototype, similar to Bigelow’s Genesis I and Genesis II modules already in orbit, but this time docked to a manned station.

What is interesting however about this article above is that reveals the names of the seven countries that have signed an agreement with Bigelow for future use of the company’s orbiting stations:

In another interesting development, Bigelow has named the seven sovereign customers who’ve expressed interest in leasing space aboard a future Bigelow commercial space station. Bigelow has preliminary agreements with the United Kingdom, the Netherlands, Australia, Singapore, Japan, Sweden and the United Arab Emirate of Dubai, according to Reuters. According to another report by Leonard David, Bigelow expects to have two BA 330 modules ready for construction of Space Station Alpha by late 2016. The Bigelow 330 is a much larger module, weighing 43,000 pounds with a diameter of 22 feet and length of 31 feet.

Bigelow Aerospace previously announced that it plans to charge sovereign customers $23 million for a 30-day stay aboard a Bigelow space station. That price includes space transportation, astronaut training, and consumables.

How the Bigelow module added to ISS will change the space equation.

How the Bigelow module added to ISS will change the space equation.

Looking a bit further down the road, the potential launch of a Bigelow BEAM module, particularly if it takes place on a SpaceX Falcon 9 booster could be a harbinger of much greater things to come. As Mars visionary Robert Zubrin and many others have observed, the addition of an inflatable module similar to that being considered for the station, to the SpaceX Dragon 2.0 capsule greatly increases the available space and capability of a future Dragon to serve both as a Mars transfer vehicle, and / or surface habitat. Add in the introduction of Falcon Heavy, and the pieces for an alternate vision of far more affordable (and timely) inner system exploration begin to fall into place.

Stewart Money has it exactly right. I have never accepted the claim that Orion was the only spacecraft being built that would be capable of going beyond low earth orbit. Add the right components to any manned vehicle, and you have an interplanetary spaceship.

The trick of course is adding the right components. For both Orion and Dragon, the present assumptions are much too nonchalant about what those components are. For humans to prosper on an interplanetary mission, the vessel requires a lot more than a mere capsule and single module.

The demo mission of robotic refueling of satellites on ISS goes forward this month.

Robot refueling of satellites: The demo mission on ISS goes forward this month.

As much as I celebrate this work, conceived and designed by engineers at the Goddard Space Flight Center (the same people who ran the missions that maintained the Hubble Space Telescope), I worry that nothing will come of it. The demo mission itself is designed to duplicate exactly the refueling of several climate satellites already in orbit whose lifespans are ending merely because they are running out of fuel. If the ISS demo succeeds, the next natural step would be to plan an actual robotic mission to refuel these satellites.

The worrisome part is that NASA rarely follows through on this kind of research. For example, the agency did tests of an ion engine back in the early 1970s, and it wasn’t until the late 1990s before they finally flew a mission using that technology. Worse, the federal budget situation probably means there is no money to fly such a mission.

Hopefully, some private company will take a look at this engineering, which is all in the public domain, and decide to use it for their own purposes.
