Remembering ColumbiaAn 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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Very True. The shuttles were so much more economical, capable, and flexible, then anything done before, or proposed to follow; Something like it must be fielded to support and real commercial activities or development in space.
They were the first real step to changing space from a field for international posturing, to a significant economic sphere. A dream were now abandoning, but not I’m sure forever.
