SpaceX to offer NASA its own plans for a heavy-lift rocket

SpaceX is putting together its own plans to provide NASA a heavy-lift rocket. Key quote:

Fast-track development, multi-use and low cost are key, says [SpaceX owner Elon] Musk. β€œThe development timeframe is on the order of five years and would come to fruition before Obama’s likely second term ends. It has got to fit within a NASA budget that fits in 2008 levels, and it’s got to have operational costs when functioning that is as close to zero as you can make it. That latter point demands that whatever components are in use for super-heavy lift must be in use for launching other satellites for say, geostationary commercial and government customers. If not, then the likelihood of success in my opinion is zero.”

X-37B has returned successful to earth

After more than seven months in orbit, the unmanned X-37B space plan has successfully returned to Earth. Key quote:

“Boeing and the Air Force are building another X-37B vehicle scheduled for launch in the spring of 2011.”

Update: Since several different reports are listing slightly different totals for the number of days in orbit, I’ve edited my note above to be less precise. I could add up the days myself, but that involves more math than I prefer to do!

More caves on Mars

And damn, do I want to rappel into them!

This week’s release of images from the HiRISE camera on Mars Reconnaissance Orbiter included these spectacular photos of two deep pits, approximately 180 and 310 meters in diameter and located aligned with a series of depressions that suggest additional passages at their base.

The first image shows the pits in the context of the surrounding terrain. From the caption:

These pits are aligned with what appears to be larger, degraded depressions. The wispy deposit may consist of dark material that has been either blown out of the pits or from some other source and scattered about by the local winds.

The next two images are heavily processed close-ups of each pit in order to bring out the detail within. From the caption:

The eastern most and smaller of the two pits contains boulders and sediment along its walls and brighter aeolian dune sediments on its floor. The larger, western most pit contains sediment and boulders with faint dune-like patterns visible on the deepest part of the floor. Both pits have steep eastern walls and more gently sloped western walls that transition gradually into the pit floor. Steep resistant ledges containing boulders that overhang and obscure the pit floors form the eastern walls.
