Two weeks of Tweets
Forgot to post this last week, so it's two weeks' worth. If you'd like to see these in real time, Follow me at Twitter. A word on some conventions: "RT" means "Retweet" -- I'm repeating something that somebody else said. Anything preceded by an "@" symbol is the username of someone else on Twitter. Twitter is a microblogging service that limits updates to 140 characters in length; I use it primarily to post links to stories I don't have time to write about here on the blog and to mention really really tiny bits of news that aren't worth full blog entries.

Wow, this is slower than an SR-71: RT @LCROSS_NASA Where am I now? Cruisin' at 0.78km/s(1753mph). Have just 1,685,000km to go.

Oh man do I wish I could go to this workshop on Asteroid TC3 in Sudan, with field trip: http://bit.ly/7tjNs Anyone want to blog from it?

Oh boy -- the only scientist on the LRO press briefing is the Laser Altimeter guy. Can't wait to see that data!!!

Uranus is at opposition today. So Saturn, the Sun, Earth, and Uranus are all in a neat line (if you view solar system from above) today.
hursday, September 17, 2009 6:00 AM
Saturn is in solar conjunction today, which explains why no astronomers (am or pro) are getting good photos of it with rings seen edge-on.

Oops! Almost forgot the second kid's birthday. It's Opportunity's third landing anniversary, measured in Martian years. Happy b-day, Oppy!

TONS of press releases coming out of EPSC meeting: Titan valleys; Mars polar winds; map of Ganymede; much more. I'll summarize some later. [NOTE: I really wanted to get to these this week, but just ran out of time. Next week, I hope.]

Yay! Lunar Recon Orbiter is now in its 50-km science orbit -- which means camera can now get images at 50 cm/pixel. http://bit.ly/4pN7v9

Haven't heard about the status of LRO's orbit insertion burn yet, but they have promised a press briefing with pictures on Thursday morning.
uesday, September 15, 2009 12:18 PM
RT @LRO_NASA: Orbit #1000 about the Moon! Mission Orbit Insertion (MOI) burn today to lower into mission orbit of 50 km.

Today is the 50th anniversary of the first hard landing of a spacecraft on the Moon (Luna 2). Wonder if LROC will spot its remains?

Lunar Reconnaissance Orbiter is doing final instrument calibration, prepping for Mission Orbit Insertion (MOI) burn tomorrow. (via LRO_NASA)

Opportunity's on the road again! Having spent ~50 sols on a detour to study huge meteorite Block Island, on sol 2004 she zoomed NW.

Baby Sanaya was just dropping to sleep when the Shuttle's BOOM BOOM woke her! Too bad she won't remember.
riday, September 11, 2009 6:04 PM
BOOM BOOM! Anahita heard it too!
riday, September 11, 2009 5:50 PM
Stuck in in-laws' back yard in Santa Clartita, CA I've no chance of seeing the shuttle but I should hear it!
riday, September 11, 2009 5:45 PM
Hm. I'll be in Santa Clarita area this evening when Shuttle lands at Edwards AFB. Will I be able to see or hear anything?

Finally! Images and maps of LCROSS impact site are now on the mission's website: http://bit.ly/Conmi

RT @LCROSS_NASA: Actual lat/lon for impact will be in sweet spot in Cabeus A that is not crater center. Info will be posted soon on website.

Here's the press release on the LCROSS impact site. I can't find any photos or maps online yet. http://bit.ly/15m39O

Just announced: LCROSS will smash into crater Cabeus A, located at 82.2° S, 39.1° W near lunar south pole and "very observable" from Earth.

Lunar Reconnaissance Orbiter's commissioning phase is complete! It'll be placed in its circular science orbit Sep 15. http://bit.ly/ZE9J1
riday, September 11, 2009 9:24 AM
Tonight the Moon is in the same phase as it will be next month when LCROSS hits it. Press briefing tomorrow about the site choice.

All you skeptics out there, go get They Might Be Giants' new CD/DVD "Here Comes Science" for kids & people with kids. "Science is real..."

Annoyed that all the official Hubble sites couldn't tell me WFC3's field of view, but it was at the top of the Wikipedia page (164 arcsec).

NASA has selected a target for LCROSS's lunar impact. Press briefing on Friday at 11 am PDT on NASA TV -- I'll be watching!

RT @plutokiller: We just got a snap shot of Hylonome, as far away as Uranus, with the new camera on HST. Data downloading. Me salivating.

The study also suggests that only ~1 comet shower has happened since Cambrian Explosion, so comets likely didn't cause (many) extinctions.
unday, September 6, 2009 5:23 PM
Huh. A new study suggests long-period comets may originate closer to the Sun than formerly thought (10 times closer!): http://bit.ly/NtSOR
