A couple of tidbits from today's Deep Impact preview briefing
Today was the press briefing that previewed the upcoming Deep Impact flyby of Hartley 2.
DPS 2010: Pluto and Charon opposition surges, Nix and Hydra masses, Pluto and Eris compositions
An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.
Deep Impact approaching Hartley 2
The Deep Impact spacecraft team has released a third image from their approach to comet Hartley 2, and for me, three images is an invitation to make an animation!
365 Days of Astronomy Podcast: The Flight of Hayabusa
Today the 365 Days of Astronomy podcast aired my contribution, The Flight of Hayabusa, a recap of that dramatic mission.
Early warning for close approaches of two house-sized asteroids
Most of you have probably heard by now of two small asteroids, both in the neighborhood of 10 meters in diameter, recently discovered on trajectories that pass unusually close to Earth.
Deep Impact snaps first image of flyby target comet Hartley 2
Deep Impact is rapidly approaching its next -- and final -- target, comet Hartley 2, which it will fly by on November 4.
The Potential to Destroy Civilization? Now on YouTube
Visualization can help the brain comprehend what words and numbers can struggle to covey. There's a YouTube video posted by
2008 LC15, the first Trojan asteroid discovered in Neptune's L5 point
Congratulations to Scott Sheppard and Chad Trujillo for identifying the first known L5 Trojan asteroid of Neptune!
The Stardust Sample Catalog
It never ceases to amaze me how much science is being wrung out of the few grams of material that were returned to Earth by the Stardust mission.
Color portrait of asteroid 21 Lutetia
Since it doesn't look like the Rosetta mission is going to be releasing any color versions of their Lutetia close-encounter images any time soon, I figured it was time to make one.
How does Lutetia compare to the other asteroids and comets visited by spacecraft?
Almost a week after Rosetta flew past Lutetia, the asteroid is now a distant pinprick of light to the spacecraft, and the science team is getting down to the business of analyzing their data.
Rosetta's Lutetia pictures
I saw these pictures for the first time just 10 minutes before boarding my flight back home, and forced myself to download everything I could find as quickly as possible without pausing to actually look at them.
Lutetia -- and Saturn!!
A quick post of just one of the gorgeous images from Rosetta's flyby of Lutetia today; for more, see the Rosetta Blog. But this one was just too pretty to wait for.
Rosetta Lutetia flyby successful; approach images posted; high-res images yet to come
All appears to be going very smoothly on Rosetta through, and after, its flyby today of asteroid (21) Lutetia.
Rosetta's Lutetia navigation campaign complete
Rosetta's most important job over the last few months has been to observe how the position of asteroid (21) Lutetia shifts against the background of fixed (fixed, that is, as far as Rosetta can see) stars.
Three days to Lutetia for Rosetta!
On July 10, 2010, at 15:44:56 UTC, the Rosetta spacecraft will fly within 3,162 kilometers of the largest asteroid yet visited by a spacecraft.
A look inside the Hayabusa sample capsule
A very brief item posted on the Hayabusa website included two pictures of the interior of its sample return capsule, one of which shows a particle.
One month, one journal, so many missed space stories!
Or: Emily reads you the table of contents of Icarus.
Lutetia in Rosetta's sights
It's unimpressive now, but in a few weeks the pinpoint of light at the center of this photo of a starry sky will loom very large to Rosetta's cameras.
