Hubble At 25

The Hubble Space Telescope has now been in space for 25 years.  After a rough beginning that necessitated a dramatic repair mission by shuttle astronauts, Hubble has helped spark a revolution in our understanding of the universe.

Future science historians may well christen this period The Hubble Era.

Paul Spudis

Paul Spudis is senior staff scientist at the Lunar and Planetary Institute in Houston, and an expert on the Moon.  He advocates using robots to mine lunar water ice to establish fuel depots-- water yields hydrogen and oxygen, which makes an excellent rocket fuel when correctly recombined.

He also wants to use robots to support the establishment of a permanent human presence on the Moon.

It is reminiscent of an idea offered by Randa Milliron, now CEO of Interorbital Systems, several years ago.

That time is consistent with estimates made using other methods.

Vulcan Aerospace

Paul Allen, who made billions by co-founding Microsoft with Bill Gates, has created a new company, Vulcan Aerospace, that will be tasked to find innovative, cost-reducing ways to reach space.

Allen also supports the Allen Telescope Array, the largest project yet undertaken by the SETI Institute in its search for extraterrestrial intelligent radio signals.
