NASA has just published a detailed timeline for the Mars InSight landing Monday



[ad_1]

On Monday, November 26, the latest part of NASA's high-tech hardware will finally find its way to the surface of Mars. This is an InSight lander, and it will listen carefully to the heartbeat of the planet and hopefully reveal a large number of amazing secrets about Mars, but before doing that, it must be really, good, land.

It all starts at 2:40 a.m. EST, with the separation of landers from the rocket stage that drives it to Mars, and that's when the real pleasure begins. Here's the full details, through NASA's Jet Propulsion Laboratory:

  • 11:40 pm PST (2:40 p.m. EST) – Separation from the stage of the voyage that took the mission to Mars
  • 11:41 pm PST (2:41 pm EST) – Turn to direct the spacecraft correctly to enter the atmosphere
  • 11:47 AM PST (2:47 pm EST) – The atmosphere comes in around 12,300 mph (19,800 kph), starts entry, descent and landing phase
  • 11:49 pm PST (2:49 pm EST) – Heating the peak of the protective heat protector reaches around 2,700 ° F (around 1,500 ° C)
  • 15 seconds later – Peak deceleration, with intense warming causes temporary dropouts in radio signals
  • 11:51 noon PST (2:51 noon EST) – Placement of parachutes
  • 15 seconds later – Separation from the heat shield
  • 10 seconds later – Deployment of three landing gear
  • 11:52 AM PST (2:52 AM EST) – Activation of the radar that will feel the distance to the ground
  • 11:53 AM PST (2:53 pm EST) – First take on radar signals
  • 20 seconds later – Separation from the rear shell and parachute
  • 0.5 seconds later – The retrorockets, or descent machines, start shooting
  • 2.5 seconds later – Starting from "gravity rotation" to bring landers to the right orientation for landing
  • 22 seconds later – InSight starts to slow down to constant speed (from 17 mph to a constant 5 mph, or from 27 kph to 8 kph) for a soft landing
  • 11:54 AM PST (2:54 pm EST) – Estimated touchdown on the surface of Mars
  • 12:01 PM PST (3:01 pm EST) – "Sounds" from the InSight X-band radio directly back to Earth, showing InSight still alive and functioning on the surface of Mars
  • Not earlier than 12:04. PST (3:04 pm EST), but maybe the next day – The first picture of InSight on the surface of Mars
  • Not earlier than 5:35 pm PST (8:35 pm EST) – Confirmation from InSight via NASA's Mars Odyssey orbiter that the InSight solar circuit has been deployed

As you can see from the schedule, the entire landing process will take several hours to complete, and there are many places where things can go awry. NASA has a remarkable track record of successful Mars landings so we don't anticipate any accidents, but JPL's mission control will be on the edge of its seats at all times.
