SpaceX is planning its own spaceport about three miles north of Mexico at the southern tip of Texas.

SpaceX had been looking at sites at various potential sites, including ones in Florida, Hawaii and Puerto Rico. Company officials have said they plan to operate out of Cape Canaveral and Vandenberg Air Force Base as well. A third, commercial launch site frees them from range restrictions that exist at the other two locations.

The actual cost to launch

7:30 am

In writing this short post on the efforts of Lockheed Martin and Orbital Sciences to launch rockets for the small satellite market, Clark Lindsey made this comment:

It costs around $50 million to launch a Orbital Sciences Minotaur 4, which can put 1,730 kg into LEO while the Lockheed’s Athena 2 will cost around $65 million to put 1,712 kg into LEO. SpaceX currently posts charges $54M – $59.5M for launching to LEO 10,450 kg (equatorial) and 8,560 kg (polar). If SpaceX is able to sustain these prices in routine operation, it will obviously result in some disturbance to the launch industry.

Let’s deconstruct these numbers again, this time listing them by the cost per kilogram:

Europe has shut down the production line producing their ATV cargo craft for ISS.

10:39 am

Is this good or bad news? Europe has shut down the production line producing their ATV cargo craft for ISS.

Confronted by parts obsolescence and waning political support, the European Space Agency has shut down subsystem production lines for the Automated Transfer Vehicle as member states debate how they will contribute to future international space exploration efforts, according to top spaceflight officials.

ESA has launched three of the five ATVs it agreed to launch, with the remaining two scheduled in 2013 and 2014. What happens after that remains unclear. It seems from the article the European partners don’t seem interested in upgrading the ATV, and instead seem willing to let the as-yet untried U.S. commercial companies carry the load.

Commercial flights by U.S. spacecraft will make up the rest of the lost capacity with the end of the ATV program.

The pressure continues to build on a successful Falcon 9/Dragon flight on April 30.

French engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.

Swiss engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.

The motor weighs only seven ounces, and could work on satellites as small as four inches cubed.

Up to now, it wasn’t possible to reduce the size of maneuverable satellites below a certain point because of the size of their large thruster engines. If it is now possible to provide nano satellites with thrusters, it will be possible to significantly reduce the cost, and more importantly, the payload weight, of satellites. And with a lower payload weight, it will be possible to create a market for smaller rockets, which are much easier to build and far cheaper.

This kind of news makes me more confident that the new commercial space industry truly has a future.

The Buzz Lightyear toy that flew on space shuttle has been donated to the Smithsonian.

The Buzz Lightyear toy that flew on space shuttle has been donated to the Smithsonian.

This news item illustrates the sad state of the American space program, when the arrival at a museum of a foot-high plastic toy that had been in space merits major news coverage. Worse, if we instead wanted to bring this toy back to ISS, we can’t, at least not without begging help from someone else.

Boeing vs Boeing.

Boeing vs Boeing.

The story describes how Boeing is considering upgrading the X-37B to become a manned ferry to ISS, thus putting it in direct competition with the company’s other manned capsule, the CST-100.

At the American Institute of Aeronautics and Astronautics’s Space 2011 conference in November, Boeing’s Arthur Grantz revealed that the company is studying a new derivative of the Boeing/USAF X-37B. The new X-37C would be 65-80% larger than the current B version. Launched by an Atlas V rocket, X-37C could carry pressurized or unpressurized cargo or 5-6 astronauts. Grantz is chief engineer in charge of X-37 at the Boeing Space and Intelligence Systems Experimental Systems Group .

Hat tip to Clark Lindsey.

Last night a piece of space junk missed ISS, but not by much.

Last night a piece of space junk missed ISS, but not by much.

The debris was only 8.7 miles from the station when it zipped by at about 16,000 miles per hour. That is very close, and had it hit, it would have done very significant damage.

The fragment was from an old Russian satellite, Cosmos 2251, that collided with an Iridium satellite in 2009, producing hundreds of fragments more than two inches across.

In discussions the last two days managers for the space programs of Europe and China began laying the groundwork for a Chinese docking at ISS.

In discussions the last two days, managers for the space programs of Europe and China began laying the groundwork for a Chinese docking at ISS.

The United States, which paid for and built the bulk of ISS, has no way of getting its own astronauts to the station. The United States at present also has no way to bring cargo up to the station.

The result: We no longer own our own space station. Though the U.S. has strict laws on the books to prevent the transfer of technology to the Chinese, restricting communications by government officials with China, the Europeans do not. And since they can send cargo to ISS while we cannot, they feel free to negotiation with the Chinese for the use of our space station. Moreover, the Russians I am sure will heartily endorse these negotiations.

And what can the U.S. government do? Nothing.

Instead of focusing on a solution to this situation, the members of Congress tasked with supervising NASA want NASA to build a giant heavy-lift rocket (SLS) to use with the Orion capsule, neither of which is designed to go to ISS. Moreover, neither will be capable of flying humans into space until 2021, one year after ISS is presently scheduled to be shut down. Even then a single flight will cost billions, which makes this system useless for resupplying ISS.

And people wonder why I consider these elected officials stupid. And if they aren’t stupid, they surely are irresponsible and incompetent, at least when it comes to the American space program.

Europe successfully launched its third unmanned freighter to ISS early this morning.

The 13-ton cargo freighter is loaded with about 7.2 tons of supplies, including food, water, clothing, experiments and fuel for the space station, according to NASA. The unmanned ATV-3 is the heaviest load of cargo ever delivered to the station by a robotic spacecraft, ESA officials said in a statement.

Stupidity on display

8:38 pm

In hearings Wednesday, several members of Congress suggested that NASA force the new competing commercial space companies to combine their efforts in order to save money.

Rep. Frank Wolf (R-Va.) asked NASA Administrator Charles Bolden during a March 21 hearing on the agency’s 2013 budget the same question he asked of the White House’s chief science adviser last month: would NASA’s partnership with commercial companies to develop astronaut transports be cheaper if the companies competing for NASA funds combined their efforts into a single “all for one and one for all” project?

Similarly, Senator Kay Bailey Hutchison (R-Texas) made the same stupid argument in her continuing effort to keep the funding of the Space Launch System, the rocket-formerly-called-Constellation, as high as possible, at the cost of cutting everything else in NASA if necessary.

If you needed any evidence that members of Congress are ignorant idiots, you only need read the comments of these elected officials at these hearings to get your proof. Wolf or Hutchison as well as several others from both parties very clearly haven’t the slightest idea what these various space companies are building. Nor do they have the faintest notion of the difficulties entailed in building these manned space vessels.

Russia’s deputy prime minister today blasted the Russian space agency and one space contractor for the scandals and public backbiting involving both.

8:39 am

Soap opera: Russia’s deputy prime minister today blasted Vladimir Popovkin, the head the Russian space agency, and one space contractor for the scandals and public backbiting involving both.

The [contractor’s] accusations apparently come as a response to Popovkin’s comments on Monday. The official accused “space industry contractors” of disseminating false rumors about him because they were dissatisfied with his attempt to reform the industry. Popovkin was hospitalized earlier this month because of exhaustion caused by a hectic schedule and frequent jet lags, according to official statements. Some media reported it was due to injuries sustained in a brawl.

Private space station builder Bigelow is hiring again.

5:47 pm

This bodes well: Private space station builder Bigelow is hiring again.

One interesting tidbit from this article is the description of the company’s negotiations with NASA to attach a Bigelow module to ISS.

The company has been negotiating with NASA for about two years on the potential deal, and that Bigelow has completed various planning and development milestones for NASA. “We’ve been in a series of discussions with NASA over the past two years, with regard to the BEAM project,” Gold told Space News. “They were initiated as part of a proposal in 2010, and we’re hopeful an announcement will be made in the not-too-distant future.”

NASA gave no sign that a deal with Bigelow was imminent. “We do have a no-cost contract with Bigelow to cover early requirements development [for BEAM] but it is not for the flight article,” NASA spokesman Josh Buck said in a March 20 email. “The Agency has not made a decision to go to a flight system yet.” [emphasis mine]

Two years to discuss “planning and development,” and still no decision. My guess is that NASA management doesn’t want to buy a Bigelow module, as it would be relatively cheap and therefore wouldn’t spread much money to NASA centers. They just can’t say no for political reasons.

And if they do want to do it, the slow pace of their decision-making process demonstrates clearly why they shouldn’t be entrusted to build anything in the future.

The FAA has issued a draft environmental impact statement required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

Isn’t it nice to live in a free country? The FAA has issued a draft environmental impact statement, required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

If the Wright Brothers had had to jump through the modern bureaucratic hoops required by today’s federal government, they probably wouldn’t have gotten their airplane off the ground until after World War I.
