#DPS2017: Progress report on Mars Reconnaissance Orbiter images of comet C/2013 A1 Siding Spring

Emily Lakdawalla • October 20, 2017

Three years ago, on October 19, 2014, comet C/2013 A1 Siding Spring passed within 138,000 kilometers of Mars. At the 2017 meeting of the Division for Planetary Sciences of the American Astronomical Society, we heard a progress report on Mars orbiter imaging of the comet's nucleus.

Congress gives NASA's planetary science division some love (and a Mars orbiter)

Jason Davis • July 19, 2017

The House of Representatives proposed $2.1 billion for NASA's planetary science budget, which would be an all-time high. Part of the increase would be used to start work on a new reconnaissance and communications orbiter.

Schiaparelli investigation update; crash site in color from HiRISE

Emily Lakdawalla • November 23, 2016

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.

Subsurface Water Ice in Utopia Planitia, Mars

As she did before for Curiosity, Emily Lakdawalla has searched through the HiRISE image archive for photos of the Opportunity landing site and sorted them all out so that you don't have to.

Schiaparelli crash site imaged by HiRISE

Emily Lakdawalla • October 27, 2016

Following up the detection of the Schiaparelli crash site by Mars Reconnaissance Orbiter CTX, the higher-resolution HiRISE camera has now definitively identified the locations of lander impact site, parachute with backshell, and heat shield impact site on the Martian surface.

Likely Schiaparelli crash site imaged by Mars Reconnaissance Orbiter

Emily Lakdawalla • October 21, 2016

Just a day after the arrival of ExoMars Trace Gas Orbiter and its lander Schiaparelli, Mars Reconnaissance Orbiter has taken a photo of the landing site with its Context Camera, and things do not look good.

Gullies on Mars: Wet or Dry (Ice)?

Tanya Harrison • August 17, 2016

Martian gullies were in the spotlight last week thanks to a NASA press release stating they were "likely not formed by liquid water" based on spectral results. But how does this stack up against their morphology?

HiRISE image coverage of the Curiosity field site on Mars, Version 3.0

Emily Lakdawalla • February 05, 2016

There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after five revisions and updates, it's now version 3.0 of the list.

NASA's Mars Announcement: Present-day transient flows of briny water on steep slopes

Emily Lakdawalla • September 28, 2015

NASA held a press briefing today to publicize a cool incremental result in the story of present-day liquid water on Mars. How big a deal is this story? Was all the pre-announcement hype justified? Is this just NASA discovering water on Mars for the zillionth time? What does this mean for things many space fans care about: life on Mars or future human exploration?

A Workhorse at Mars

Tanya Harrison • September 11, 2015

The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is almost a silent star at Mars. The latest MRO data release brought the total number of available CTX images to over 70,000, covering well over 90% of the Red Planet at a stunning resolution of 6 meters per pixel.
