The US space agency Nasa has landed a new robot on Mars after a dramatic seven-minute plunge to the surface of the Red Planet.<\/p>\n

The InSight probe\u00a0aims to study the world’s deep interior, and make it the only planet – apart from Earth – that has been examined in this way.<\/p>\n

Confirmation of touchdown came through on cue at 19:53 GMT.<\/p>\n

It ended an anxious wait in which the robot radioed home a series of updates on its descent.<\/p>\n

Nasa’s mission control at California’s Jet Propulsion Laboratory (JPL) erupted into cheers when it became clear InSight was safe on the ground.<\/p>\n

The agency’s chief administrator, James Bridenstine, celebrated what he called “an amazing day”. President Trump had rung to offer his congratulations, he told reporters. And the director of JPL, Mike Watkins, said the success should remind everyone that “to do science we have to be bold and we have to be explorers.”<\/p>\n

\"InSight<\/span><\/figure>\n

InSight is now sitting on a vast, flat plain known as Elysium Planitia, close to the Red Planet’s equator. Before landing, Nasa had dubbed it the “biggest parking lot on Mars”.<\/p>\n

The first picture of this landscape came back very quickly, within minutes. It showed a smudged, fisheye view of the robot’s surroundings.<\/p>\n

The image was taken through the translucent lens cap of a camera positioned on the underside of the lander. The dust kicked up in the descent obscured much of the scene, but it was still possible to make out a small rock, one of the probe’s feet and the sky on the horizon.<\/p>\n

A later picture captured by a camera on InSight’s topside was much clearer.<\/p>\n

What happened in the landing?<\/h2>\n

Like all previous landing attempts at Mars, Insight’s race to the surface – the first attempt since 2012 – was a tense affair.<\/p>\n

Stage by stage and metre by metre, the robot reported back its progress.<\/p>\n

It had entered the atmosphere faster than a high-velocity bullet, using the combination of a heatshield, parachute and rockets to bring itself to a gentle stop.<\/p>\n

InSight’s first critical task on landing was to deploy its solar panels, which were stowed for the descent.<\/p>\n

The robot absolutely had to start generating power to operate its systems and to warm equipment in the sub-zero temperatures that persist on the Red Planet. Notification of the panels’ set-up came seven hours after landing.<\/p>\n

One of the big achievements in the InSight mission so far has been the role played by the two briefcase-sized satellites that were sent to Mars along with the robot lander.<\/p>\n

It was these mini-spacecraft, called MarCO A and B, that relayed the probe’s signals back to Earth during the plunge to the surface. The duo cost less than $20m and their technologies are now sure to feature much more prominently on future interplanetary missions.<\/p>\n

And as if to underline their capabilities, the little satellites also took a picture of Mars.<\/p>\n

“Having successfully brought all the data back from InSight during its exciting entry, descent and landing (EDL) sequence – what you see before you is an image taken roughly 4,700 miles from Mars, about 10-15 minutes after EDL itself,” explained MarCO chief engineer Andy Klesh.<\/p>\n

What is different about the InSight mission?<\/h2>\n

This will be the first probe to dedicate its investigations to understanding Mars’ interior. Scientists want to know how the world is constructed – from its core to its crust. InSight has three principal experiments to achieve this goal.<\/p>\n
