An evening pause: On this day eight years ago, the space shuttle Columbia broke up as it returned from orbit. Rather than watch that sad sight again, I’d rather remember the shuttle’s achievements. Watch this footage of Columbia’s first landing on April 14, 1981, which proved it was possible to glide powerless back from space and land safely on a runway. Though we as a nation might be abandoning this approach right now, future generations will use this as their standard way to return to Earth.
Several things to note as you watch the video. First, the shuttle’s angle of descent is extremely and frighteningly steep, until the very last moment. And every shuttle landing is like this. The shuttle is heavy, but it is still attempting to glide powerless to a landing. To do so it needs the thickness of the atmosphere combined with high speed to give it lift. Thus, it plows downward at a mucher higher speed and angle than any airplane, then quickly levels out at the last moment.
Secondly, this first landing did not have a drogue chute to slow the shuttle down. Rather than complicate things, they simply let the shuttle roll until it came to a stop.

“We want to be able to put an object up into space, materials, technology and so forth, test them out, bring them back and examine them,” said Richard McKinney, deputy under secretary of the Air Force for space programs. “In that respect, this is a test vehicle.”

Reality meets feel-good politics: Electric cars and their cold-weather shortcomings. Key quote:
“If you live in an area where the winters get extremely cold an all-electric vehicle will have to be garaged and equipped with some kind of plug-in battery warmer for it to be effective in the coldest months of the year. Keep these thoughts in mind if you’re planning an electric car purchase; we don’t want you finding out the range of your car has been halved when it’s five below zero and you’re fifteen miles from home.”
Today is the 25th anniversary of the Challenger accident. There are innumerable links from many sources talking about the event, too many for me to list here. You can find most at this link on Jeff Foust’s website, spacetoday.net.
Though I think it is very important for us to remember and honor these events, I have become somewhat disenchanted with the modern American obsession with memorials and anniversaries. Rather than build a memorial, I’d much rather we focused entirely on building new spaceships, new space stations, and new lunar bases, while flying multi-year missions on ISS, all in preparation for exploring and colonizing the solar system.
If we actually made the solar system a place for humans to live in and explore, we would build a far better memorial to those who have sacrificed their lives for the sake of exploration. And I think these heroes would be far more pleased by that memorial than by a stone statue or emotional op-ed that describes their courage.

More solar sail news: Japan’s solar sail mission, IKAROS, has been extended for a year. Key quote:
With the extended lease on life, the team will try new navigational tricks, such as varying the sail’s angle toward the sun and changing the craft’s trajectory. Mori called these “risky” maneuvers because they are not sure if the sail will remain fully extended. They intend to model the sail’s behavior and the craft’s response to plan future solar sail missions.
How’s this for your evening television entertainment: Beginning 8 pm on Saturday, NASA TV will show the docking of the next Russian Progress freighter to ISS.
