The first spacewalk

An evening pause: Forty-six years ago today Alexei Leonov became the first man to walk in space. This Soviet-era film shows practically the entire event, using footage from two cameras. Unfortunately, I don’t speak Russian and it is not subtitled. I’d love it if someone out there could provide a translation.

Several things to note as you watch:

Satellite Builders express contempt for MDA’s refueling plans for Intelsat

Sour grapes: Satellite builders express contempt for MDA’s refueling plans for Intelsat orbiting satellites.

No surprise here. If Intelsat can extend the life of its satellites, than it won’t have to buy them as often from these builders, something the builders clearly don’t want.

Putting ISS to use

Putting ISS to use. Key quote:

Under consideration is using the entire station and its six-person crew as an analog for a deep-space human exploration vehicle en route to Mars. An internal team is studying the feasibility and value of such an exercise in the summer of 2012. “We might start with a small window, like a 30-day window, with actual time delays with what we’d expect with a Martian communications system,” Gerstenmaier says. “We may freeze our consumables on station, in the sense of saying that we’ve started our voyage to Mars, and see how well we do in our predictions.”

Maiden flight of the space shuttle Discovery

An evening pause:I had played this video as an evening pause back in November, when I thought the last mission of the space shuttle Discovery would be launched. Now that it has finally landed, completing its final mission, I think worthwhile to once again go back in time and watch a film of the shuttle’s maiden flight, launched August 30, 1984, narrated by the astronauts themselves. Note that the female astronaut on this flight is Judith Resnik, who died a little over a year and a half later in the Challenger accident.
