As Curiosity was landing safely on Mars, many of you noted that the Jet Propulsion Laboratory engineers orchestrating the whole thing were eating an awful lot of peanuts. In fact, each workstation boasted a little commemorative jar of peanuts. Seriously, what is up with all those peanuts?
Discovery News has an answer. And it's surprisingly interesting.
Turns out, this is a JPL-specific tradition, dating back to 1964, when the lab's funding was on the line after the Ranger program—unmanned missions to photograph the Moon—weren't living up to expectations. In fact, six Ranger missions in a row had failed.
This was the heritage leading up to Ranger 7. There was talk that JPL should be shut down, that a university-affiliated center couldn’t handle a rigorous spaceflight program. There were suggestions that the program had been sabotaged -- a worker found a small polyethylene bag with 14 screws and a lock washer in one of the sealed electronic modules in Ranger 7’s television subsystem.
Just before Ranger 7 launched to the moon on July 28, mission manager Harris Schurmeier handed out peanuts to ease tensions. He figured chewing or playing with them on the table would give his team something else to focus on.

"It comes complete with shout-outs to Carl Sagan and Neil deGrasse Tyson," reports the Washington Post, which dug into the story behind its creation. Half a million views so far, huh? Best NASA PSA ever. Read the rest
What a beautiful video by Mark Rober, of NASA's Jet Propulsion Laboratory: "I was able to work on NASA JPL's Curiosity Mars Rover for 7 years. This video is an attempt to capture what it felt like to have 7 years of your life vindicated in the 7 minute landing. Honestly one of the coolest moments of my life so far.
As regular readers of this blog will recall, I asked a question of the Mars Curiosity team about imaging technologies during the post-landing press conference at NASA JPL a few days ago.
Related: Digital Photography Review now has an interview with the Mars rover camera project manager. Above, the 34mm (115mm equiv.) Mastcam from the Curiosity rover. This was developed by Mike Ravine and his team at Malin Space Science Systems, a contractor for NASA. Ravine explains how they developed the 2MP main imaging cameras used to transmit those breathtaking images back from Mars.
The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says [Ravine], but the biggest factor was the specifications being fixed as far back as 2004. Multi-shot panoramas will see the cameras deliver high-res images, he explains, but not the 3D movies Hollywood director James Cameron had wanted.
'There's a popular belief that projects like this are going to be very advanced but there are things that mitigate against that. These designs were proposed in 2004, and you don't get to propose one specification and then go off and develop something else. 2MP with 8GB of flash [memory] didn't sound too bad in 2004. But it doesn't compare well to what you get in an iPhone today.'

Mars24 is a Java application which displays a Mars sunclock, a graphical representation of the planet Mars showing its current sun- and nightsides, along with a numerical readout of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle and path for a given location on Mars.
Created at NASA's Goddard Institute for Space Studies.
Thomas Hayden at science blog The Last Word On Nothing has a wonderful little interview with Scott Maxwell (@marsroverdriver), who works at JPL as a Mars rover driver. Coolest job ever, right?
I had the honor and pleasure of meeting Maxwell at JPL a few weeks before Curiosity touched down, when I accompanied Miles O'Brien on a shoot about MSL for PBS NewsHour. Loved him, and I love how he describes what makes his job so exhilarating:
I don’t think I’ll ever forget the first time I drove her. It was just a few meters along a simple path — we wouldn’t even bother to yawn at it today — but it was magic to me then, as it’s magic to me now. I went home and should have slept, but all I could do was stare at the ceiling, in awe that right then, on Mars, there was a robot doing what I told it to do. It was dead amazing, and that feeling has never left me and I hope it never will.

Engineers at NASA's Jet Propulsion Laboratory today received and published the first photograph shot by the Navigation cameras on NASA's Curiosity rover.
It shows the shadow of the rover's now-upright mast in the center, and the arm's shadow at left. The arm itself can be seen in the foreground. The navigation camera is used to help find the sun -- information that is needed for locating, and communicating, with Earth. After the camera pointed at the sun, it turned in the opposite direction and took this picture. The position of the shadow helps confirm the sun's location. The "augmented reality" or AR tag seen in the foreground can be used in the future with smart phones to obtain more information about the mission.
The Atlantic has a doublewide photo gallery of Associated Press photos from the night of the Mars Landing. I'm in this shot (#13). The whole gallery is a great reminder of the range of emotions and excitement you feel when you're witnessing one of these historic space events. I will never forget this night, as long as I live! And I know I'm not alone in that. If you want to know what joy looks like, click onward. Read the rest
[Video Link] It took just minutes for Curiosity to complete her landing sequence on Mars. But the journey to that point took years of work back here on earth. The celebration of the rover's successful landing continues, and the mission itself will continue for 2 years. On this PBS NewsHour segment, Judy Woodruff talks to science correspondent Miles O'Brien and John Grunsfeld of NASA about Curiosity and the years NASA scientists spent planning the journey to Mars.
