After traveling for 36 weeks from earth, and approximately 567 million kilometers (352 million miles), it was all down to the last 7 minutes to determine if the long travel was worth the wait.
By some called “7-minutes of terror”, the NASA Curiosity rover had to survive a complicated and intricate procedure to finally touch down on the surface of Mars. After months of waiting, now finally the scientists and engineers can breath a sigh of relief as the rover is securely seated on the surface of Mars.
The intense period called the entry, descent and landing (EDL) phase of the mission began when the spacecraft reached the top of the Martian atmosphere. At this time the Mars Science Laboratory spacecraft, carrying the Curiosity rover was traveling at about 5,900 meters per second (13,200 miles per hour). EDL ended about seven minutes later, with the rover placed stationary on the surface.
The NASA controllers, and the rest of the world, relied on NASA’s Mars Odyssey orbiter to provide confirmation of a successful landing. Odyssey was turned to the right direction before the landing procedure started so it could listen to Curiosity during the landing. The rover touched down on Mars at 1:31 a.m. EDT.
