NASA has a responsibility to be a good customer. This means one that knows what it wants when it walks in, how much it wants and how often, and what it wants to pay.
In the search for life on other planets, scientists are looking beyond single-celled organisms and are developing techniques that would help them detect multicellular life.
If we allow private enterprise to explore and take advantage of the Moon's resources, we may set ourselves on the road to energy independence.
Fifty years ago today, Soviet cosmonaut Yuri Gagarin became the first human being to orbit the Earth. During the flight, 190 miles above the globe, he sang to himself.

While preparing for a recent Tai Chi class, I was struck by the importance of space in generating power in Yang-style Tai Chi. This led me to think about how critical space can be in generating powerful results in anyone's life.
Switching our perspective from physics to biology undoes some of the biggest "facts" we've been taught about the world, including life and death, time and space, and God and the universe.
It's raining planets. Members of the science team for NASA's Kepler telescope announced the tentative discovery of more than 1,200 worlds orbiting distant stars. Of these, approximately four dozen are candidates for being Earth's doppelgangers.
In the present uncertainties of the space program, a great transitional opportunity exists. As we reflect back upon the tragic loss of Challenger, we must rise to the challenge in the spirit of those who have so bravely shown the way forward.
The Sahara desert was once fertile grassland. This fact has been common knowledge in the scientific community for some time, but scientists are still grappling with what changed.
"Postcards from Mars" were taken with an eye for lighting, framing, color, depth of focus -- the same kinds of factors that Earth-bound landscape photographers routinely consider.
We all depend on satellites, whether or not we know it. Making space safe and secure for both satellites and space travel will depend largely on enhancing space situational awareness.
What if I told you that everywhere you point--be it the tip of your pen, or the outermost tip of Cape Horn--there is a hidden, 6-dimensional space so small that we cannot see it nor ever set foot in it?
This one-minute excerpt comes from a special colloquium celebrating the 25th anniversary of the SETI Institute. Watch a video of Dana Backman giving...
