Hayabusa's return: round up some of the amazing photos, movies, and artworks that were posted and shared and Tweeted and re-Tweeted over the previous dozen hours or so.

How radio telescopes get "images" of asteroids

Emily Lakdawalla • April 29, 2010

Every time I post a radio telescope image of a near-Earth asteroid, I get at least one reader question asking me to explain how radio telescopes take photos, so I'm hereby writing a post explaining the basics of how delay-Doppler imaging works.

APOLLO program pinpoints location of Lunokhod 1 retroreflector

Emily Lakdawalla • April 26, 2010

With the recent Lunar Reconnaissance Orbiter imaging of the Lunokhod 1 rover, scientists on the APOLLO project were finally able to do something that scientists have been dreaming of for more than three decades: shoot the rover with a laser.

Hayabusa's coming home

Emily Lakdawalla • April 21, 2010

It really looks like Hayabusa is going to make it home. Hayabusa's sample return capsule will be returning to Earth on June 13, 2010, landing in the Woomera Prohibited Area, Australia at about 14:00 UTC.

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.

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
