House Science Committee to hold hearings on impact danger

Forgive my absence gentle readers, I was on a well deserved R & R after the preceding, and life changing, two months (I had some evergreen content timed to go, I thought. But, well, for whatever reason Microsoft won again …). After which I was deemed healthy enough to return to work full time. So, last week the House was supposed to hold an important hearing on the danger posed by Near Earth Objects, a hearing so important it was at first postponed indefinitely and, I’m now told by trustworthy sources, rescheduled for next week on March 19. It’s interesting to hear what planetary scientists think of the people who are actually on that committee and by extension the party that controls it: [Read more…]

Mars flyby and other links

This was supposed to be a secret until this coming Wednesday, and it was secret, right up until someone spilled the beans almost a week early:

Buzz is building about a planned 2018 private mission to Mars, which may launch the first humans toward the Red Planet. A nonprofit organization called the Inspiration Mars Foundation — which is led by millionaire Dennis Tito, the world’s first space tourist — will hold a news conference on Feb. 27 to announce the 501-day roundtrip mission, which will aim for a January 2018 launch.

Yes, there are many unresolved questions. But these people are not flakes; they are serious veteran space travel professionals. I think they’re really thinking about doing this. There will be more info soon. [Read more…]

Name that dwarf planet moonlet!

Pluto

 

The debate about Pluto’s planetary status has simmered down, although I was always partial to the way Alan Stern, the Director of New Horizons mission to Pluto, explained it to me: it’s just a dwarf planet. We don’t call a small dog a different species just because they’re small, we just call it a miniature, something like that makes sense for Pluto and its cohorts like Sedna or Ceres. But we now know Pluto has two new moons, or dwarf moons or moonlets if we want to extend the debate, and SETI wants your help naming them! [Read more…]

Fomalhaut B, the Zombie Planet, roams around its star once

Space.com — The latest observations of the odd planetary system revealed that the dusty debris disk surrounding the star Fomalhaut is much wider than previously thought. The debris belt spans a vast region of space between 14 billion and 20 billion miles (22.5 billion to 32.1 billion kilometers) around the star. Stranger still: The planet Fomalhaut b appears to approach with 4.6 billion miles (7.4 billion km) of its star at the closest point in its orbit, then swing way out to a point about 27 billion miles (43.4 billion km) away at the farthest point. Scientists call the extremes of such a planet’s path a highly eccentric orbit. Fomalhaut b’s path, scientists say, sends the planet crashing through the surrounding debris disk during its 2,000-year orbit around its parent star.
