If we're serious about human exploration of Mars (or even the moon), then we have to come up with realistic estimates, factoring in all kinds of unforeseen costs.
There is either a decades-long conspiracy involving tens of thousands of scientists who have imbedded false formulas into the basic physics and chemistry textbooks, or climate change is real.
Backyard astronomers, get ready to feast your eyes on the skies. In April the red planet returns to prime time, and the Moon shows us a darker side.
Mars One chief Bas Lansdorp's plan to send the first four humans on a one-way trip to establish a permanent human colony on Mars in 2025 is going full-steam ahead -- as is public and sometimes vitriolic criticism of his mission.
After nearly a year of study and collaboration between the Inspiration Mars Foundation and some of the best and brightest minds in the space industry, the most logical systems architecture for a Mars flyby mission has become crystal clear.
The newest name-it-and-claim-it-in-space game, a Uwingu/Mars One partnership, invites the public to participate in naming the 500,000 unnamed craters on Mars. Five dollars gets you a small crater; the big bucks buy you more.
Alongside me the day in 1992 when we launched, in the historical background, were others -- the African-American engineers, rocket scientists, physicists, administrators, technicians and life scientists who helped build the space program.
No one can dispute that Mars One intends to send the first humans to Mars, or that these humans will die there, because there are no plans to bring them back to Earth. But does a one-way mission to a planet where we might actually be able to survive constitute a suicide mission?
You may be wondering why anyone would want to take a one-way trip to Mars, and honestly I wonder that myself. However, Dutch company Mars One plans to do just that, and they received over 200,000 applicants vying to take the trip.
I stopped shooting film exactly six years ago next month, in the spring of 2008. Within my small circle of colleagues, I was one of the last to do so....
Each of us seems to think ours is the only worthwhile goal. And of course we also each have our own favorite spacecraft, our own perfect solutions and systems and approaches, and everyone else be damned, because my way is the space highway.
The 472 women, including me, who have advanced to what Mars One calls Round Two have a reasonable expectation of being among the first to colonize Mars. It's even conceivable that I could be the one to take the sure-to-become-iconic first footstep onto the surface of the red planet.
I believe both sides -- those who are pro-toasters in space and those who are pro-studs to the stars -- are lost, losing, and will in the end be seen as engaged in a dated and rhetorical dance that will have no meaning, if the rest of us choose the right path moving forward.
Last week, as you may recall, I used this space to pay homage to one of man's finest culinary inventions: the doughnut. In short, I confessed to occas...
If we can achieve Mars without a major increase in budget, it would be fiscally irresponsible not to commit. We have made a long-term investment in space. Let's make the most effective use of taxpayer and private dollars and accomplish something bold and inspiring for the nation and the world.
In spite of what you may read in the media, for a majority of NASA employees, it is my feeling that the question has yet to have a valid answer.
