NASA has just published a detailed landing schedule on Mars InSight – BGR on Monday



On Monday, November 26, the latest piece of NASA's high-tech hardware will finally find its way to the surface of Mars. This is an InSight landing and she will listen carefully to the heartbeat of the planet, and we hope to reveal a whole bunch of great secrets to Mars, but before it does, it really has to have land.

NASA will stream the mission information by providing real-time comments and updates on the mission's status. If you just can not wait for the big day, NASA has just published a schedule when it expects to reach specific points in the landing process, just by the minute, and that's quite interesting.

It all starts at 2:40. EST, detaching the landing gear from the rocket scenes that pushed him to Mars, and then the real fun begins. Here's a complete breakdown through NASA's Jet Engine:

  • 11:40 AM PST (2:40 EST) – Separation from the cruise scene that carries the Mars mission
  • 11:41 PM PST (2:41 EST) – Rotate to navigate the spacecraft properly to enter the atmosphere
  • 11:47 PM PST (2:47 AM EST) – Atmospheric entry at 19,800 km / h, starting the entry, descent and landing phase
  • 11:49 PM PST (2:49 EST) – Peak heating of the thermal shield reaches about 2700 ° F (about 1500 ° F)
  • 15 seconds later – Deceleration of the tip, with strong heating, which may lead to temporary dropout of radio signals
  • 11:51 PM PST (2:51 EST) – Parachute deployment
  • 15 seconds later – Separation from the heat shield
  • 10 seconds later – Place the three legs on the ground
  • 11:52 PM PST (2:52 EST) – Activate the radar that will sense the distance to the ground
  • 11:53 PM PST (2:53 EST) – First acquisition of a radar signal
  • 20 seconds later – Separation from the rear shell and the parachute
  • 0.5 second later – Retro-generators or launch engines start firing
  • 2.5 seconds later – Start the "gravity curve" to get the landing in the right landing direction
  • 22 seconds later – InSight begins to decelerate to a steady speed (from 17 mph to constant 5 mph or from 27 kph to 8 km / h) for its soft landing
  • 11:54 PM PST (2:54 AM EST) – Expected touch on the surface of Mars
  • 12:01 PM PST (3:01 EST) – "Beep" from InSight's X-band radio directly to Earth, which shows that InSight is alive and functioning on the surface of Mars
  • No sooner than 12:04. PST (3:04 EST), but eventually the next day – The first InSight image on the surface of Mars
  • No sooner than 5:35. PST (8:35 EST) – InSight Confirmation by NASA's Mars Odyssey Orbition That InSight Solar Tables Are Installed

As you can see from the schedule, the entire landing process will take several hours to complete, and there are many places where something can go wrong. NASA has remarkable results from successful landings on Mars, so we do not expect any trouble, but the control of the JPL mission will be on the brink of its place all the time.
