LOS ANGELES (Reuters) -- NASA scientists presented striking early images from the picture-perfect landing of the Mars rover Perseverance, including a selfie of the six-wheeled vehicle dangling just above the surface of the Red Planet moments before touchdown.
The color photograph, likely to become an instant classic among memorable images from the history of spaceflight, was snapped by a camera mounted on the rocket-powered "sky crane” descent-stage just above the rover as the car-sized space vehicle was being lowered on Thursday to Martian soil.
The image was unveiled by mission managers during an online news briefing webcast from NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles less than 24 hours after the landing.
The picture, looking down on the rover, shows the entire vehicle suspended from three cables unspooled from the sky crane, along with an "umbilical” communications cord. Swirls of dust kicked up by the crane’s rocket thrusters are also visible.
Seconds later, the rover was gently planted on its wheels, its tethers were severed, and the sky crane - its job completed - flew off to crash a safe distance away, though not before photos and other data collected during the descent were transmitted to the rover for safekeeping.
The image of the dangling science lab, striking for its clarity and sense of motion, marks the first such close-up photo of a spacecraft landing on Mars, or any planet beyond Earth.
"This is something we’ve never seen before,” Aaron Stehura, a deputy lead for the mission’s descent and landing team, describing himself and colleagues as "awe-struck” when first viewing the image.
Adam Steltzner, chief engineer for the Perseverance project at JPL, said he found the image instantly iconic, comparable to the shot of Apollo 11 astronaut Buzz Aldrin standing on the moon in 1969, or the Voyager 1 probe’s images of Saturn in 1980.
He said the viewer is connected with a landmark moment representing years of work by thousands of individuals.
The image was taken at the very end of the so-called "seven-minutes-of-terror” descent sequence that brought Perseverance from the top of Mars’ atmosphere, traveling at 12,000 miles per hour, to a gentle touchdown on the floor of a vast basin called the Jezero Crater.
