Some wisdom from Pravda: “Humans explore space only for profit.”

Some wisdom from Pravda: “Humans explore space only for profit.”

And then there’s this, from the U.N., not surprisingly published at MSNBC: “Private property in outer space: The other side of the argument.” To quote the U.N. expert: “More rules are needed, but I am also of the opinion that you do not need to create property rights [in space].”

It is a sad world when support for capitalism, private property rights, and competition comes from Pravda, while in the U.S. such ideas get slapped down.

European subsidies have put Arianespace in the black.

1:25 pm

European subsidies have put Arianespace in the black for 2011 and 2012.

The key quote however is this:

But ESA governments have made clear they are not happy having to cover losses, especially since the workhorse Ariane 5 rocket, introduced in the mid-1990s, is well past its teething stage and has conducted 47 consecutive launch successes. Its last failure was in late 2002.

Arianespace has dominated the commercial launch market in recent years, yet can’t make a profit. In this case, however, I suspect that if the company lost its subsides it would somehow find a way to finally reduce its budget.

Assuming it gets the necessary funds, Boeing anticipates flight tests of its CST-100 reusable manned capsule in 2016.

10:11 am

More news from commercial space: Assuming it gets the necessary funds, Boeing anticipates flight tests of its CST-100 reusable manned capsule by 2016.

This story is part of the on-going lobbying effort to convince the Luddites in Congress to subsidize the new commercial space companies. To get some context, even if Congress gives NASA all of the money it has requested for this program, the annual cost will still be less than a third of the NASA-built Space Launch System, and will get us four different ways to get humans and cargo into orbit, and do it in far less time.

Despite protests from the U.S. and South Korea, North Korea is continuing preparations for the launch an Earth observation satellite.

Despite protests from the U.S. and South Korea, North Korea is continuing preparations for the launch an Earth observation satellite.

North Korea recently entered into a food aid agreement with the U.S., which requires the Asian nation to halt long-range rocket launches in exchange for critical resources to stem the country’s widespread poverty and famine.

Officials from the U.S. and South Korea have said that the Unha-3 launch is a violation of this agreement, and could carry significant consequences. South Korean officials have said they may even shoot down parts of the Unha-3 rocket if they breach the state’s borders.

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

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.

7:54 am

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.
