Remember the "seven minutes of terror"? Those tense, breathtaking moments, back in August, between the descent of the spacecraft carrying the Mars Curiosity rover into the Martian atmosphere and the vehicle's (ultimately successful) landing on Mars?
NASA remembers. So it periodically checks up on one of the tools that allowed for Curiosity's safe landing: the parachute that floated Curiosity gently down onto the rocky surface of the Red Planet. Images from NASA's Mars Reconnaissance Orbiter have captured the parachute lying in its rocky grave. But they've shown it doing something else, too: shifting its shape.
Photos obtained by the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera show the chute flapping, beautifully and a bit hauntingly, in the Martian wind -- a high-tech instrument turned into a friendly ghost. The seven photos GIFed above were captured by HiRISE between August 12, 2012 -- just after Curiosity's landing -- and January 13, 2013.
Researchers have used HiRISE to produce many more time-lapses of Mars like this, as well as moments of spectacular drama. HiRISE's first image of Curiosity's parachute captured the spacecraft suspended from the chute during descent through the Martian atmosphere:

The cameras shot the chute doing its job, and they continue to record its retirement -- one that has the rare distinction of playing out on another planet.
