I learned* that the Kepler craft (NASA artist sketch on right – this is the device that will look for “other earths” – see below) is all go to try for launch later today! Extract from an announcement that went around:
On 6 March (EST, 7 March in UTC) there are two opportunities for a launch into the Earth trailing orbit. The first window is at 6 March, 10:49:57 p.m. EST (UTC: 7 March, 03:49:57) and the second window is at 11:17:44 p.m. EST (UTC: 7 March, 04:17:44). If Kepler is not launched tonight there is a another possibility at approximately the same time tomorrow night.
Countdown will begin 3 hours before launch and Kepler separation into Earth trailing solar orbit will take place 3709 sec into flight. First contact after separation is expected 4640 sec into flight.
For more information, and to follow the launch live, here are some links: NASA TV, Launch Blog, Spaceflight.
I noticed that Amy Mainzer is over at the Kennedy Space Center to see the launch. She begins to talk about it here on her (excellent) blog. You might want to check back there in case she does a nice report on it. Check out Phil’s Bad Astronomy blog for more on this too. He says he’ll be tweeting and all. (Yes. Tweeting. There, I have used that word in its recent new context/meaning in a sentence for the first time. I feel a bit silly.)
Bill Stone is quite an engaging speaker, it has to be said. I heard him on the BBC World Service, being interviewed about his hopes and plans to change the way we do things in space. It is a spirited case that he makes, where he deliberately invokes the spirit and the words of Sir Ernest Shackleton and other great explorers going off into the unknown. The audio is here. (If you come to this late, search their archive here.)
Then I checked and sure enough there was a TED talk from him last year. See here. You can see him in action as well, although the BBC interview is complementary […] Click to continue reading this post →
Last week the Guardian did a special podcast about Barack Obama’s science policies, and the challenges that lie ahead for the new administration. It’s actually rather good (at least the parts I’ve heard so far – I’m listening to it in pieces while travelling) and I recommend it. They have lots of guests, many of whom you’ve maybe heard of (Lesley Stone, Martin Rees, Diana Liverman, Chris Mason, P Z Myers, Lawrence Krauss, Martin Barstow), and the issue is explored from several angles, from climate change, through stem cells, to the space program.

As you may have heard, the Phoenix craft on Mars (remember? seven minutes of terror?) which had already been running beyond its design lifetime, has probably sent its final message from Mars. There is not enough daily solar energy (now that it is Winter) coming in to support its energy needs.
I’ve been running around so much today I forgot to actually mention the event for which I’ll be acting as host tonight, here at USC. This is how I quickly described it to my colleagues, but bear in mind that it is open to all:
I’d like to remind you one last time about the Apollo Visions and Voices event today. Whether it interests you or not, please encourage your students to go. It is the College Dean’s V+V event for the semester, and was chosen to have a focus that would attract science and engineering students and faculty to sit with our friends and colleagues from the arts and humanities. It is at 7:30 pm in Bovard, with a reception at the end. I think that it will be very interesting and enjoyable.
This is quite remarkable. There’s actually been an image (see left) taken of a planet orbiting another star. There are hundreds of known extrasolar planets in orbit around other stars (see lots of earlier posts), and evidence for them has been indirect, since they are too tiny and too dim (having no light of their own) to image directly. You can learn of their existence by their effects on their parent star, and/or on the light it casts. (The image left is courtesy of the Gemini Observatory. The University of Toronto scientists used the Gemini North telescope on Mauna Kea in Hawaii and its adaptive optics technology to make the image.)
Well, the new orbiting instrument, GLAST (Gamma-ray Large Area Space Telescope – launched June 11th this year) has passed all its tests with flying colours, apparently, and is working well. NASA has now renamed the craft the Fermi Gamma-ray Space Telescope, after Enrico Fermi. There’s a press release here.
The craft is a wonderful combination of the fields of particle physics, astrophysics and cosmology, and will teach us so much about the universe (such as the nature of dark matter), and so it is exciting to hear that it all on track.
Excitingly, they’ve also released images of the early results of the observations, and you can read more about them in the press release too. Here’s a sky map made from the observations.

Today is the 50th anniversary of the day the USA replied to the world-changing Sputnik launch by the USSR almost four months earlier (see my post), as well as Sputnik 2 (carrying the dog Laika) a month after. In some sense, the space race began in earnest with this launch of the craft called Explorer.
It’s not going to be naked-eye visible, but give a thought tonight to the 250 metre asteroid (2007 tu24) that is going to swing by close to earth tonight! Or, if you have a “modest” telescope, go and look at it. It’s going to scrape by at 1.4 times the distance of the moon. That’s pretty close, by astronomical standards, and gives scientists a chance to see a near earth object rather more closely than usual. From the […] Click to continue reading this post →
Inside meaning the inner part of the Solar System. Messages meaning the new pictures from MESSENGER spacecraft.
MESSENGER is short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging. Now you and I know that they spent a bit of time coming up with the unpacking of the name, wanting of course to have the name MESSENGER because that’s what the Mercury of mythology was – the messenger of the Gods, among his other duties. Nice. However I’d have been really impressed if they’d managed to call it QUICKSILVER, and found a way to unpack that – any takers?
Anyway, I digress. In more news showing the triumph of the wisdom of relatively cheap unmanned exploratory craft, MESSENGER sent some wonderful pictures of Mercury this week, along with lots of other scientific data that will help us learn a great deal about the innermost planet. Here’s the one that’s been going around a lot (click for impressive larger version):
A little over a month from now, Mars might be hit by an asteroid! There’s a 1 in 75 chance (due to uncertainties about the exact trajectory), according to the people tracking the object’s progress right now. The 50 metre wide object is due to pass within 300000 miles of Mars at about 6 a.m. EST (3 a.m. PST) on Jan. 30, 2008. Quoting quite a bit from the press release from JPL/NASA: […] Click to continue reading this post →
Today’s the 50th anniversary of an event that might be thought of as an extreme way of nationally getting really serious about Science education. Sputnik was launched by the USSR. The little pioneering satellite passed overhead several times a day, sending a powerful beeping signal over a radio channel. America immediately became scared, worried and paranoid and essentially declared it a national emergency to respond by a focus on better education in some science and technical subjects. Songs were written. The entire culture was changed.
Fear and paranoia are certainly not the ways I’d like to see us come back to recognizing the value and urgency of improved science education (not the least […] Click to continue reading this post →
