Every Mars landing attempt as of June 2020
Two maps by The Planetary Society show all the places we've landed or crashed on Mars as of June 2020.
Ten times the solar system reminded us sample collection is hard
Some of the biggest discoveries we make in planetary science rely on the seemingly simple act of picking up and analyzing pieces of other worlds. When things go awry, scientists and engineers can sometimes squeeze amazing science out of a tough situation.
Pretty pictures of terraced craters on Mars
Check out this unusual crater on Mars. It's not a very big one, less than 500 meters in diameter, and yet it has two rings. Most craters on Mars this size are simple bowl shapes. What's going on here?
Who is the photographer behind Mars rover photos? Answer from Mark Lemmon
A Mars imaging scientist answers the question: who is the
Mars Exploration Family Portrait
Jason Davis put together this neat summary of the checkered history of Mars exploration.
Phoenix is dead...long live Phoenix!
The latest HiRISE images of the Phoenix polar lander, taken near Mars' northern summer solstice, show why we haven't heard from the spacecraft since it fell silent on November 2, 2008: it appears the solar panels have collapsed.
Happy solstice -- on Mars
It's the solstice on Mars today: summer in the north, winter in the south.
No signal from Phoenix
After three listening campaigns taking place from January through April, Mars Odyssey has detected no signal from Phoenix.
LPSC, Day 1: Spirit and Phoenix
Where to begin with the Lunar and Planetary Science Conference (LPSC)?
Odyssey's going to start listening for Phoenix
It's been the second most popular question I get from readers:
Happy Christmas on Mars!
This was so cute I had to repost it -- and record it too.
No, they can't push with the arm to free Spirit
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.
HiRISE sees Phoenix in the Martian spring
These Mars Reconnaissance Orbiter HiRISE images of the defunct Phoenix lander in the early dawn light of northern spring have been out for some time, but no one had accomplished the difficult task of locating the Phoenix hardware in them until this week.
Phoenix Mission Receives OK to Listen for Sounds on Mars
Good news, everyone! The jillions of you who have asked me
Danes on Mars
I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as
More things to see in the amazing HiRISE image of Phoenix' descent
I have posted several times about the amazing photo captured by HiRISE of Phoenix under its parachute as it descended. There have been two common questions I've received about the photo: was there any color data taken, and what more can I tell you about how hard it was to take the photo? I've got answers to both questions for you today.
Yep, it's ice!
The Phoenix mission confirmed it this morning: the disappearing act pulled by those chunks of bright material in the Dodo trench pretty much nails the identification of the bright material as ice, which is great news for the mission. Ice is what Phoenix went all the way to Mars to study; it's what the team has been aiming for all these years.
Phoenix Sol 2 press conference, in a nutshell
Emily hits the high points of today's press conference.
What's up in the solar system for the week of May 12
It's time to check in on what's going on with our trusty robots around the solar system.
What's up in the solar system for the week of April 28
I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.
