On Monday, November 26, NASA's latest high-tech space equipment will finally be on the surface of Mars. It's the InSight lander, and he'll listen carefully to the heartbeats of the planet and hopefully reveal a whole series of awesome secrets to Mars, but before he does, he really has to land.
NASA will broadcast live mission control workflow, providing feedback and updates on the status of the mission in real time. If you can not wait for the big day to come, NASA has just released a schedule indicating when it plans to reach specific points of the landing process, up to the minute, which is quite interesting.

It all starts at 14:40 EST, with the landing of the rocket scene separating it from the rocket that pushed it to Mars, and that's where the real fun begins. Here is a complete overview, via NASA's Jet Propulsion Laboratory:
- 11:40 PST (2:40 pm EST) – Separation of the cruise stage that led the mission on Mars
- 11:41 am PST (2:41 pm EST) – Turn to properly orient the spacecraft so that it enters the atmosphere
- 11:47 am PST (2:47 pm EST) – Enter the atmosphere at approximately 12,300 mph (19,800 km / h), beginning the phase of entry, descent and landing
- 11:49 PST (2:49 pm EST) – Maximum heat shield protection is approximately 2,700 ° F (approximately 1,500 ° C)
- 15 seconds later – maximum deceleration, intense heating causing possible temporary cuts in radio signals
- 11:51 Pacific Time (2:51 pm EST) – Parachute deployment
- 15 seconds later – Separation of the heat shield
- 10 seconds later – Deployment of the three legs of the undercarriage
- 11:52 PST (14:52 EST) – Activation of the radar that will detect the distance to the ground
- 11:53 AM PST (2:53 pm EST) – First radar signal acquisition
- 20 seconds later – Separation of the aft hull and parachute
- 0.5 second later – The retrorockets, or downhillers, start firing
- 2.5 seconds later – Beginning of the "gravity turn" to bring the landing gear into the proper orientation for the landing
- 22 seconds later – InSight begins to slow down at a steady speed (from 17 mph to a constant of 5 mph, or 27 to 8 km / h) for its soft landing
- 11:54 AM PST (14:54 EST) – Touchdown expected on the surface of Mars
- 12:01 pm PST (3:01 pm EST) – "Beep" from InSight's X-band radio directly to Earth, indicating that InSight is alive and working on the surface of Mars.
- Not earlier than 12:04 PST (3:14 pm EST), but maybe the next day – first image of InSight on the surface of Mars
- No earlier than 5:35 pm PST (8:35 pm EST) – Confirmation of InSight via NASA's Mars Odyssey Orbiter stating that InSight's solar panels have been deployed
As you can see from the calendar, the landing process will take several hours and there are many places where something may go wrong. NASA has a remarkable history of successful landings on Mars. So we do not anticipate any incident, but JPL's mission control will be at the edge of its seat all the time.
