MAVEN dodges Phobos, with (maybe) a little help from Curiosity

Posted by Emily Lakdawalla on 2017/03/06 06:00 CST | 2 comments

This week MAVEN had to execute a short rocket burn in order to prevent a future collision with Phobos. Curiosity (and other rovers) may have played a role in those trajectory predictions.

Curiosity update, sols 1548-1599: Serious drill brake problem as Curiosity drives through Murray red beds

Posted by Emily Lakdawalla on 2017/02/03 02:21 CST

Since my last update, the Curiosity mission has developed a better understanding of the problem that prevented them from drilling at Precipice, but its intermittent nature has slowed the development of a workable solution that will allow them to use the drill again. In the meantime, the rover has driven onward, making good use of its other instruments.

A writing sabbatical

Posted by Emily Lakdawalla on 2017/01/24 07:43 CST | 5 comments

Four years ago, I announced that I was writing a book about Curiosity, describing the mission from its inception through its nominal mission. I am still not done, so am taking a three-month break from other work -- including this blog -- in order to focus and finish. I'm seeking scientists and engineers to serve as guest bloggers.

Go see Hidden Figures, and bring your kids. Despite its serious subject matter, the movie is joyful, often funny, and, in the end, triumphant.

Spaceflight in 2017, part 2: Robots beyond Earth orbit

Posted by Emily Lakdawalla on 2016/12/30 12:22 CST | 4 comments

What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.

Curiosity update, sols 1489-1547: Drilling at Sebina, driving up through Murray, drill problems at Precipice

Posted by Emily Lakdawalla on 2016/12/12 05:09 CST | 1 comment

It's been a drive-heavy two months for Curiosity. Since my last update, the rover has drilled at a site named Sebina, then traveled about 500 meters to the south across increasingly chunky-looking Murray rocks to a new attempted drill site at Precipice. They were planning to attempt a new drilling technique at Precipice, but encountered a new problem with the drill instead.

Schiaparelli investigation update; crash site in color from HiRISE

Posted by Emily Lakdawalla on 2016/11/23 11:28 CST | 11 comments

ESA issued an update on the Schiaparelli landing investigation today, identifying a problem reading from an inertial measurement unit as the proximate cause of the crash. Meanwhile, ExoMars Trace Gas Orbiter is operating its science instruments for the first time this week, and HiRISE has released calibrated versions of the Schiaparelli crash site images.
