To Infinity And...Your Questions

For some it's the ultimate frontier with (nearly) endless possibilities for exploration -- both manned and robotic. For others it's not worth the time and effort (and risk).

What are your thoughts? Should we invest more in earth science or deep-space telescopes? Who should be the next NASA chief? Does the Obama administration see the same emphasis on returning to the moon? What's out there?

Lots of questions, and I'll be hosting a live webcast on starting at 1:30 p.m. EDT on Monday, May 11, so send your thoughts/queries to my Twitter account, Facebook, or post them here.

Watch Daniel Sieberg host Space Shuttle launch Webcast, 1:30 p.m. Monday, May 11
My guest during the webcast will be former shuttle program manager Wayne Hale, who will join us until about 1:50p. After that point, I'll stay online as we carry the live launch of Atlantis at 2:09p, as the crew is scheduled to rendezvous with the aging Hubble telescope and complete a slew of risky repairs.
