The robotic lander had to cover some 300 million miles (483 million km) to get there after it was launched aboard an Atlas V rocket from the Vandenberg Air Force Base in California on May 5.
A Treacherous Journey
We don’t have to tell you that landing on the Red Planet is not an easy feat: in fact, as Space.com points out, half of all Mars missions have failed to arrive safely in the past.
It’s a treacherous landing. InSight reached a breakneck speed of 12,000 miles per hour before slowing to just five miles per hour as it touched down with the help of a supersonic parachute and an array of small thrusters.
Destination: the Elysium Planitia plain — a large, mostly flat surface that straddles the equator, close to some of the largest volcanic regions on Mars.
Pulse of the Planet
The InSight team is planning to glean data about Mars’ ancient history. To do so, it’s outfitted with:
- A seismometer to map the Martian interior (and activity)
- A heat probe that will measure the heat coming from deep below the Martian surface
- A special radio will try to glean how much Mars wobbles on its own axis as it orbits the sun
And Now We Wait
There’s still one more big hurdle to overcome: the lander has yet to unfurl its solar panel array to power the instruments on board. We’re expecting to know if the lander did so successfully in a few hours.
Then we’ll have to wait until InSight actually deploys all its instruments — and finally starts sending some long-awaited data back to Earth.
