Germany has funded a study to look into using Sierra Nevada’s Dream Chaser for its space operations.

The competition heats up: Germany has funded a study to look into using Sierra Nevada’s Dream Chaser for its space operations.

Named DC4EU (Dream Chaser for European Utilization), the project is to explore ways in which the Dream Chasercan be used to cover German and European requirements for the transportation of payloads and astronauts to the International Space Station (ISS) and for deployment as a manned or unmanned space vehicle allowing German and European scientists to conduct research under weightless conditions over extended periods of time. Given the capability which the Dream Chaser has for reaching orbits at a substantially greater altitude than the ISS, the study will determine the extent to which it is able to supply satellites or remove decommissioned satellites from their orbits.

All hail competition and private enterprise! Sierra Nevada designed it. Sierra Nevada built it. Sierra Nevada owns it. If NASA decides it doesn’t want to buy it, there is no reason the company can’t sell it to someone else, for profit.

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

[T]he reduced cooling capability means there’s less of a safety margin on the station. Todd said mission managers don’t want to risk having the Cygnus come in for a hookup under such conditions. “While we’re sitting at one loop, we’re somewhat vulnerable,” he said.

The logic here escapes me. It suggests they will stop all cargo missions to ISS until the coolant problem is solved. However, what if they can’t solve it without a spacewalk? To do that spacewalk they have to deliver an upgraded spacesuit to the station to replace the suit that had water leak problems in July, and that delivery is not scheduled until late February when the next Dragon cargo launch is scheduled.

Maybe they are considering putting that replacement suit on the Cygnus capsule so it can arrive quickly. If so, that would justify delaying the Cygnus launch for a few days.

More details about the situation here.

A private unmanned mission to Mars by 2018?

A private unmanned mission to Mars by 2018?

Dutch entrepreneur Bas Lansdorp, Mars One founder and CEO, told reporters the foundation has signed contracts with two major aerospace firms, Lockheed Martin and Surrey Satellite Technology, to develop mission concept studies, a first step toward eventual construction and launch.

The lander will be based on the design of the 2007 Phoenix Mars lander that Lockheed Martin developed for NASA. The communications satellite — the first such “geostationary” comsat in orbit around the red planet — will incorporate technologies developed by Surrey and used in a variety of operational spacecraft.

Mission concept studies are of course essential before you begin construction, but they are also a far cry from actual construction. I’ve seen literally hundreds of similar concept studies about someone’s big space plans with no subsequent follow up. Thus, I will only begin to take Mars One serious when they actually start cutting metal.
