How to Search for Exoplanets

Some methods almost sound like science fiction: Using gravity as a magnifying glass, watching stars wobble at turtle-like speeds, and searching for tiny dips in starlight.

Notes from a Red Planet: Ray Bradbury

Scott Maxwell • June 06, 2012 • 2

Mars rover driver Scott Maxwell relates a story of how he handed Ray Bradbury an opportunity to drive on Mars.

Oppy close to the edge�

Stuart Atkinson • June 05, 2012

Since you last visited, Opportunity has continued to drive downhill – well, what passes for ‘downhill’ on Cape York! – and is now not far at all from the northern edge of the Cape. From where she is now she sees the Meridiani desert stretching away to the north and west, the eastern hills on her right, and the Cape itself behind her. And around her? lots and lots of Homestake-like gypsum veins.

Rovers in the desert

I took a field trip to watch scientists and engineers play in the sand with Mars rover models, and got a bonus tour of some evidence for the "Snowball Earth" hypothesis.

Opportunity is a ROVER again!

Stuart Atkinson • May 14, 2012 • 2

After driving off Greeley Haven – where she stood patiently for 19 long weeks – Opportunity is now driving again. Not just turning, not just bumping, but driving.

An update on Opportunity, and a plea for some volunteer desktop publishing help

Emily Lakdawalla • April 03, 2012 • 2

A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.

Pretty picture: A sunset postcard and a special shadow from Opportunity

Emily Lakdawalla • February 21, 2012

It took Don Davis many hours of meticulous labor to assemble this beautiful postcard from Mars.

Dusty girl

Emily Lakdawalla • January 23, 2012

Today Opportunity sent back to Earth the last few frames of the "deck pan" self-portrait she took during the waning days of 2011. Her solar panels are very dusty, which isn't helpful. It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.
