What about the non-imaging data from spacecraft?

Emily Lakdawalla • January 18, 2010

Data from all science instruments on all of NASA's and ESA's space missions, not just cameras, is archived in the Planetary Data System and Planetary Science Archive, and almost all of that data is available online.

No, they can't push with the arm to free Spirit

Emily Lakdawalla • December 15, 2009

I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.

Hayabusa's still coming home: JAXA engineers come up with yet another creative solution

Emily Lakdawalla • November 19, 2009

Trouble has come time and again to JAXA's little Hayabusa asteroid sample return mission, yet the mission's engineers always come up with new and creative ways to solve problems.

Hayabusa stumbles on the path back to Earth

Emily Lakdawalla • November 11, 2009

JAXA issued a press release (in Japanese) on November 9 stating that one of Hayabusa's ion thrusters, thruster D, had stopped operating. Hayabusa launched with four ion thrusters, but D was one of only two that are still functioning. So the failure of thruster D is a serious problem.

Tracking the stars -- and Earth

Reports from the 2009 arctic Mars analogue Svalbard expedition

Adrienne Kish • October 06, 2009

The expedition's goals were to integrate and test two new instruments for NASA's Mars Science Laboratory rover and four for ESA's ExoMars rover.

Mars Science Laboratory Instruments: MARDI

Mars Science Laboratory Instruments: MAHLI

Ryan Anderson • September 30, 2009

Last time, I talked about the MastCam color cameras on MSL, so it only makes sense to continue with one of the other cameras: The Mars Hand Lens Imager (MAHLI).

Mars Science Laboratory Instruments: Mastcam

Ryan Anderson • September 17, 2009

A few weeks ago I gave a lunch talk at Cornell summarizing the MSL mission and particularly the instruments that it will carry and was shocked by the number of people who showed up!

Exploring Mars on Earth: The Arctic Mars Analog Svalbard Expedition

Emily Lakdawalla • August 31, 2009

High in the Arctic, just below Earth's north polar ice cap, biologists, geologists, and engineers come together in Svalbard every August to practice and prepare for an expedition to Mars.

Gravity's Bow

Timothy Reed • June 15, 2009

Timothy Reed explains how optical telescopes are tested for gravity sag, and the methods used to counteract or compensate for it.

Designing the Cassini Tour

John Smith • June 07, 2009

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Canto II: Titan's Atmosphere and the Solar Cycle

David Seal • June 03, 2009

David Seal explains the complications for Cassini coming from Titan's atmosphere and Solar Cycle.

There's more to the Hayabusa story

Emily Lakdawalla • February 07, 2009

After posting my brief "Hooray for Hayabusa" note on Thursday I got an email from the Japanese blogger "5thstar," telling me that there was more to Hayabusa's story.

Danes on Mars

Emily Lakdawalla • July 17, 2008

I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as "that Danish magnet guy," the fellow responsible for the magnet experiments on nearly every American Mars mission. The magnets were originally designed to study the properties of airborne Martian dust, which would help determine its composition.

"Return of the Falcon," a new animation of the Hayabusa mission

Emily Lakdawalla • November 26, 2007

JAXA has released a 30-minute video of the Hayabusa mission, "Return of the Falcon," combining computer animation with actual footage of the construction and launch as well as images from the spacecraft of Itokawa.

Europlanet: RADAR views of Titanian Geology

Doug Ellison • August 24, 2007

"What plays in Potsdam stays in Potsdam" - that's how Ralph described a problem I mentioned over at UMSF where I explained I couldn't combine the audio of my talk with the MOV of the slides because you're not allowed to record presentations. It's "law of the stag" for conferences. So, in the spirit of the law, here's an overview of Ralph's excellent overview of Titanian geology as seen by various RADAR passes.

Europlanet : CoRoT - Preliminary Results

Doug Ellison • August 20, 2007

ESA's planet-hunting satellite COROT bagged its first exoplanet in observations of the star COROT-Exo-1.
