Encouragement from space for Japan
I saw this posted by @Akatsuki_JAXA (the Akatsuki Venus mission's official Twitter identity) and thought it was cute so I'm sharing it here.
Dawn's instruments are being roused for Vesta approach
Today the Dawn imaging team released a photo from the main camera, the Framing Camera, symbolizing that they're preparing to start Dawn approach science; the other two science instruments, a spectrometer and a neutron detector, are also being turned on and checked out.
Neat video of Curiosity drive testing (plus a code-cracking challenge)
The Jet Propulsion Laboratory has posted a short video showing some recent testing of an engineering model of the Mars Science Laboratory in their outdoor Mars Yard; they're testing the performance of the rover's driving capability over slopes of varying steepness and covered with bedrock, compacted sand, and very loose sand.
MESSENGER successfully entered orbit at Mercury!
Just a brief post to announce that at 01:00 UTC MESSENGER completed a 15-minute burn of its main engines to enter orbit at Mercury!
How to follow MESSENGER's orbit insertion today
The day is finally here! In only five and a half hours, at 00:45 on March 18 (according to the spacecraft's clock), MESSENGER must ignite its main engine and run though a third of its fuel in only 15 minutes in order to enter its planned orbit around Mercury.
LPSC 2011: Day 4: Ted Stryk on icy moons and The Moon
Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.
Stardust: Decommissioning planned for March 24
Stardust (probably) has only a week remaining in its operational lifetime, according to a status report just posted to the mission website.
LPSC 2011: Analysis of the grains returned by Hayabusa
I'd been despairing of finding a good source for a writeup of the presentations in the Hayabusa session at last week's Lunar and Planetary Science Conference, but am happy to report that I've finally found an excellent one.
Two days from MESSENGER's Mercury arrival
Today the MESSENGER team briefed the press on the impending arrival of their spacecraft at Mercury.
LPSC 2011: Kirby Runyon on Mars, the Moon, Hartley 2, and Ganymede
Kirby Runyon, a second-year grad student at Temple University, offered to send me some writeups of selected presentations from last week's Lunar and Planetary Science Conference, and I enthusiastically agreed.
365 Days of Astronomy Podcast: A MESSENGER to Mercury
I've got another 365 Days of Astronomy podcast airing today, this one an overview of the MESSENGER mission with particular attention to what's been learned in the three Mercury flybys, and what's going to happen when it enters orbit only a little more than three days from now!
LPSC 2011: Wanted: Pioneer 10 & 11 digital data
This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.
LPSC 2011: Day 3: Deep Impact at Hartley 2
Wednesday's sessions at the Lunar and Planetary Science Conference (LPSC) on the Deep Impact flyby of Hartley 2 were one of two that I was most looking forward to, the other being this morning's talks on Hayabusa's samples from Itokawa, about which I don't yet have any notes. I am again grateful to Franck Marchis and Andy Rivkin for sending me their notes on Hartley 2.
LPSC 2011: Day 3: Moon, Mars, and Venus
Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.
Dawn Journal: HAMO2; the destination glows bright
Deep in the asteroid belt, Dawn continues thrusting with its ion propulsion system. The spacecraft is making excellent progress in reshaping its orbit around the sun to match that of its destination, the unexplored world Vesta, with arrival now less than five months away.
LPSC 2011: Day 1: Small bodies
Here are some of the noteworthy items from the morning's session on
Pretty picture: Saturn storm
To relieve this week's text-heavy LPSC posts, here's a brief one on an incredible panorama across Saturn's northern storm, taken on February 26 by Cassini and assembled by unmannedspaceflight.com member
Glory Lost - But Its Mission Must Go On
Another painful loss to NASA's mission to study Earth from space: Today a Taurus XL rocket failed to lift the Glory satellite into Earth orbit when its clam-shell nosecone refused to open, forcing the rocket and its payload into the southern Pacific Ocean.
Endeavour on Opportunity's horizon: Are we there yet?
Last week the Mars Exploration Rover team dumped another 90 sols' worth of data from Mars into NASA's Planetary Data System, the national repository for space mission data. As I did once before, I dove into this fresh pile of data to pull out Opportunity's color views of the distant rim of Endeavour crater.
Explore the Moon in 3D through the Chandrayaan-1 TMC image data set
Data from two of the cameras aboard Chandrayaan-1 are now available through the ISRO Science Data Archive (ISDA), a new(?) site that is being established to host the data from ISRO's deep-space missions.
