Cheers and applause erupted at Nasa’s Jet Propulsion Laboratory on Monday as a waist high unmanned lander, called InSight, touched down on Mars, capping a nearly seven-year journey from design to launch to landing.
The dramatic arrival of the $993m (R13.75bn) spacecraft – designed to listen for quakes and tremors as a way to unveil the Red Planet’s inner mysteries, how it formed billions of years ago and, by extension, how other rocky planets like Earth took shape – marked the eighth successful landing on Mars in Nasa’s history.
“Touchdown confirmed,” a mission control operator at Nasa said, as pent-up anxiety and excitement surged through the room, and dozens of scientists leapt from their seats to embrace each other.
“It was intense and you could feel the emotion,” Nasa administrator Jim Bridenstine said in an interview on Nasa television afterwards.
Bridenstine also said President Donald Trump and VicePresident Mike Pence had watched on television and called to congratulate the US space agency for its hard work.
“Ultimately, the day is coming when we land humans on Mars,” Bridenstine said, adding that the goal is to do so by the mid 2030s.
The vehicle appeared to be in good shape, according to the first communications received from the Martian surface.
But, as expected, the dust kicked up during the landing obscured the first picture InSight sent back, which was heavily flecked.
France’s Centre National d’Etudes Spatiales made the Seismic Experiment for Interior Structure instrument, the key element for sensing quakes.
The principal investigator on the French seismometer, Philippe Lognonne, said he was relieved and very happy at the outcome.
“I’ve just received confirmation there are no rocks in front of the lander,” he said.
And in a final crucial phase, Nasa said InSight signalled to Earth that its solar panels – twin solar arrays spanning 2.2m in width – had opened and were collecting sunlight on the surface of Mars.
