The new Augustine Commission met for the first time last week (June 17). The one-day agenda was filled with presentations on rocket-building, including reviews of NASA’s current efforts along those lines, followed by briefings on a number of possible alternatives. Suddenly, the space blogosphere ...

Last time, I outlined some of the basic principles of lunar resource utilization. The Moon is our nearest source of material resources in space and learning how to extract what we need from the Moon is a key skill in our expansion into the Solar System.All this is very well and good, but how do we...

While the resources of space have the potential to revolutionize spaceflight—giving us a much wider range of activities than are now possible, including habitation of other planetary bodies—discussions on various internet forums show that there is a lot of confusion and lack of knowledge about spac...

We sure do love our celebrities, don't we? And I don't mean whatsisname, who won on American Idol last night. I'm talking about the newly upgraded Hubble Space Telescope, whose astronaut repairmen received a call from President Obama yesterday, and will deliver live testimony from space at a Congre...

It's a big week for space telescopes. Hubble's getting an upgrade, Europe's Herschel (the largest mirror ever sent into space) and Planck observatories are on the pad awaiting a Thursday launch, and the six-year-old Spitzer space telescope is about to start its second life. Any day now (May 12 was...

Judith Young wore a light, sheer robe, almost a wrap, that reached to within inches of the floor, over silky, swishy pajama-looking clothes. Very comfortable looking, the kind of new age-y clothes an academic wears so she can devote all her energy to thinking. Her long gray hair reached down her ba...

Lunar dust sticks to everything! It’s electrically charged! It causes silicosis – astronauts on the Moon will get “black lung” disease, just like coal miners on Earth! It’s so abrasive that under its obnoxious influence, moving parts slowly grind to a halt! We can’t possibly cope with it! So m...

The Mini-SAR imaging radar aboard the Indian Chandryaan-1 spacecraft currently orbiting the Moon has been sending back some amazing images for the last couple of months. We are nearing the end of our first radar mapping season (which occurs when the sun illumination conditions on the Moon are unfa...

The Daily Planet, my new companion blog here at Air & Space magazine, highlights a speech recently given by my good friend Dr. Neil Tyson at the Space Foundation breakfast. Noted is Neil’s oft-mentioned concept that historically, three drivers are responsible for societies or nations undertaki...

There is a brief but vociferous debate about the value of human spaceflight over at Space Politics, under a discussion of the new NASA proposed budget. An often expressed opinion is that in general, humans contribute little to the scientific exploration of space. Indeed, my scientific colleagues ...

We’ve known since the beginning of the space age that the Moon has no global magnetic field. Before we returned samples from the Moon, this was thought to be well understood – compared to Earth, the Moon is a small body (1% the mass) and it rotates very slowly (almost 30 times slower). The large ...
