“Stuff Of Our Dreams”: NASA On Daredevil Mars Rover Landing Videos, Audio

NASA’s Perseverance Mars rover is seen the place it landed in Jezero Crater on Mars.

Los Angeles:

NASA scientists on Monday unveiled first-of-a-kind house motion pictures of final week’s’ daredevil Mars rover touchdown, vividly exhibiting its supersonic parachute inflation over the purple planet and a rocket-powered hovercraft decreasing the science lab on wheels to the floor.

The footage was recorded on Thursday by a sequence of cameras mounted at completely different angles of the multi-stage spacecraft because it carried the rover, named Perseverance, by means of the skinny Martian ambiance to a delicate landing inside an enormous basin known as Jezero Crater.

Thomas Zurbuchen, NASA affiliate administrator for science, known as seeing the footage “the closest you can get to landing on Mars without putting on a pressure suit.”

The video montage was performed for reporters tuning in to a information briefing webcast from NASA’s Jet Propulsion Laboratory (JPL) close to Los Angeles 4 days after the historic touchdown of probably the most superior astrobiology probe ever despatched to a different world.

NASA additionally offered a quick audio clip captured by microphones on the rover after its arrival that included the murmur of a light-weight wind gust – the primary ever recorded on the fourth planet from the solar.

JPL imaging scientist Justin Maki mentioned NASA’s stationary touchdown craft InSight, which arrived on Mars in 2018 to review its deep inside, beforehand measured seismic indicators on the planet that had been “acoustically driven” after which “rendered as audio.”

But mission deputy undertaking supervisor Matt Wallace mentioned he believed the Martian breeze represented the primary ambient sound instantly recorded on the floor of Mars and performed again for people.

The spacecraft’s mics failed to gather useable audio throughout descent to the crater ground. But they did choose up a mechanical whirring from the rover after its arrival. Wallace mentioned he hoped to document different sounds, such because the rover’s wheels crunching over the floor and its robotic arm drilling for samples of Martian rock.

“The stuff of our dreams”

But it was movie footage from the spacecraft’s perilous, self-guided trip by means of Martian skies to landing – an interval NASA has dubbed “the seven minutes of terror” – that JPL’s staff discovered notably putting.

“These videos, and these images are the stuff of our dreams,” Al Chen, head of the descent and touchdown staff, instructed reporters. JPL Director Mike Watkins mentioned engineers spent a lot of the weekend “binge-watching” the footage.

The video, filmed in coloration at 75 frames a second, exhibits motion in fluid, vivid movement from a number of angles, the primary such imagery ever recorded of a spacecraft touchdown on one other planet, Wallace mentioned.

One of probably the most dramatic moments is of the red-and-white parachute being shot from a canon-like launch gadget into the sky above the rover because the spacecraft is hurtling towards the bottom at practically two occasions the velocity of sound.

The chute springs upward, unfurls and totally inflates in lower than two seconds, with no proof of tangling inside its 2 miles (3.2 km) of tether strains, Chen mentioned.

A downward-pointing digicam exhibits the warmth defend falling away and a sweeping vista of the butterscotch-colored Martian terrain, showing to shift backwards and forwards because the spacecraft sways beneath the parachute.

Seconds later, an upward-pointed digicam captures the rocket-powered “sky-crane” car, newly jettisoned from the parachute, its thrusters firing however the propellant plumes invisible to the human eye whereas decreasing the rover to a protected touchdown spot on a harness of tethers.

A separate digicam exhibits the decreasing of the six-wheeled rover from the vantage level of the sky crane, wanting downward as Perseverance dangles from its cable harness simply over the floor with streams of mud billowing round it at landing. The sky crane is then seen flying up and away from the touchdown website after the harness cables are minimize.

A single nonetheless photograph of the rover suspended from the sky crane moments earlier than touchdown was launched by NASA on Friday amid a lot fanfare as a precursor to the video proven on Monday.

The solely earlier transferring footage produced of a spacecraft throughout a Mars touchdown was a relatively crude video shot from beneath the earlier rover, Curiosity, throughout its descent to the planet’s floor in 2012. That stop-motion-like sequence was shot at 3.5 frames per second from a single angle that confirmed the bottom regularly getting nearer however included no pictures of the parachute or sky-crane maneuvers.
