Mars Curiosity Landing: A Cheat Sheet

After a spectacular launch and a long cruise through the black reaches of space, the Mars Science Laboratory—better known as the Curiosity rover—is set for the most dangerous part of its mission: the landing in Gale Crater. Curiosity is the biggest rover ever sent to Mars, and carries the most advanced suite of instruments, in order to discover the story of the planet’s habitability.

Basics

Landing time:

Approximately 10:31 p.m. PDT on Sunday, August 5th
(Aug. 6 at 1:31 a.m. EDT | Aug. 6 at 5:31 a.m. UTC | about 3 p.m. local Mars time)

Target:

Gale Crater, near the Martian equator. Specifically, Aeolis Palus, a relatively flat area near the base of Aeolis Mons, the crater’s central mountain, also informally called Mt. Sharp.

Distance from Earth to Mars at time of landing:

248 million kilometers (154 million miles)
13.8 minutes light travel time

Sequence of events during entry, descent and landing (EDL):

  • Guided Entry – As it enters the Martian atmosphere at about 21,000 kph (13,000 mph) the spacecraft is controlled by small rockets and protected by a heat shield.
  • Parachute Descent – The spacecraft is slowed by a large parachute.
  • Powered Descent – After separating from the heat shield and the backshell, another set of rockets further slows and controls the spacecraft’s descent.
  • Sky Crane – The sky crane system lowers the rover itself on cables down to a soft landing on the surface. The sky crane then flies away.

Total time from top of atmosphere to full stop on the ground: about seven minutes. Orbiting spacecraft at Mars will relay relatively simple signals from the rover to Earth during the landing process. Pictures will come later.
