In Memoriam: Mars Rover Spirit

She had a career that lasted almost 20 times longer than expected, during which time she helped usher in a new era of understanding between our world and an alien planet.

She’s the Mars Exploration Rover Spirit. And today she is officially lost in space.

In a press release issued last night, NASA’s Jet Propulsion Laboratory—the rover’s birthplace—announced that scientists will cease trying to communicate with Spirit, which went silent on March 22, 2010.

The rover had become stuck in a sandy pit in April 2009, and efforts to have her wiggle out failed repeatedly.

In January 2010 mission managers decided they’d have Spirit stay put.

She could still do science, investigating the mineral-rich soil she was trapped in, as well as conducting experiments that benefit from a stationary data collector, such as atmospheric studies and radio probes of Mars’s axial spin.

The trick was that Spirit would first have to survive Martian winter.

“Normally we keep [the rover] warm by having it on,” like a car running its engine on a cold day, rover project manager John Callas said at a January 2010 press briefing.

Previously NASA had parked the rover each winter so that her solar panels pointed north, maximizing power collection during the long months of low sunlight.

Given her limited movement in the pit, however, this time Spirit couldn’t get into an ideal position for hibernation.

With wintertime lows around -45 Celsius (-49 Fahrenheit) on Mars, the team was worried that the rover wouldn’t get enough sunlight to keep powered *and* keep warm.

Sadly, it looks like those worries proved true.

Winter’s over now on Mars, and Spirit should have started chattering if she’d made it through the brutal winter.

But NASA’s been trying for ten months to make contact, to no avail, and today they’ll send the very last official transmission.

“We’re now transitioning assets to support the November launch of our next generation Mars rover, Curiosity,” Dave Lavery, NASA’s program executive for solar system exploration, said in the release.

Don’t forget that Spirit’s twin, Opportunity, is still trucking along on the red planet and is even now headed for a new crater to explore.

Plus, it sounds like Team Spirit isn’t completely giving up hope: “While we no longer believe there is a realistic probability of hearing from Spirit, the Deep Space Network may occasionally listen for any faint signals when the schedule permits.”

Spirit, you’ll be missed:

    You know the first colonists on Mars will make it there goal to collect the rover. They will treasure it,and make it a center point, as if it was the rock from Plymouth Rock. Its Last moment will be honoured as our first step. Stay strong. Gone but not forgotten.

    I’m excited for the next generation of robotic explorers and what the marketing department for NASA will come up with. with the huge increase in robotics used in warfare, we should be able to build robots now that put these first generation bots to shame. I am imagining giant, tank robots and flying robots and virtual reality robots which allow you and I to do the exploring right here from our computers. CAN’T WAIT!!!!! have a story to tell? tell us about it: http://stardustchannel.com maybe we’ll make it.

    You all know that she can never ACTUALLY come back, right? Awwww I wuvv her so muuuch. Even if she wasn’t stuck she still wouldn’t be able to come back. You need a return rocket, and people to be there with a Launch Pad and all that. She will Rest In Peace (thankfully not pieces at least)

    spirit is what we are…lets all take a moment to thank all those who set her free !!!

    Yes please spend more and more money looking for a glorified can opener that has outlived its use. Why we dont we use that money to look right under our own feet. Somewhere around 70% of earth still remains un-unexplored. Ridiculous.

    Fallen silent at last in an alien environment, windblown and frozen – she stands in silent testimony of a species who envisioned the task, of the engineers who made it manifest and of our struggle to explore and learn – to better understand. She speaks eloquently of us.

    WALL E can relate on this, too bad. Being alone, stranded. Just seeing the comic makes me feel sad that this precious rover couldn’t go back to our home land. Hope NASA can find a way in order for her to retrieved. Wish them luck

    The rover may have other jobs to do than to send pics to civilians. It’s probably checking out ruins of past civilizations that existed on Mars.

    Disappointing, hope they find a way to get her back home someday…

    maybe they should stop sending them to craters and start exploring the buildings and ruins there

    Maybe Marvin the Martian (of Loony Tunes fame) will repair her (LOL). But he might turn the rover into an attack machine.

    won’t she get the chance to set her wheels here on earth again. Mars, cold, desolate, harsh, does a rover which had developed a ‘link’ to her mission control crews deserve to be left behind on such place. Atleast, if NASA won’t be able to bring her home, try to wiggle her out of that pit, why don’t they use nearby rovers, atleast, keep the “SPIRIT” alive..
