Good morning from Los Angeles! Today at approximately 1954 GMT InSight will touch down in Elysium Planitia, and this is where we'll discuss all the events associated with that. NASA TV (link) will provide live coverage starting at 1900 GMT. Official status updates will be published here (link)
Here's a list of significant events (source: JPL). Times listed first are Earth-received US Pacific Standard Time (GMT-8): 11:40 a.m. PST (2:40 p.m. EST) — Separation from the cruise stage that carried the mission to Mars 11:41 a.m. PST (2:41 p.m. EST) — Turn to orient the spacecraft properly for atmospheric entry 11:47 a.m. PST (2:47 p.m. EST) — Atmospheric entry at about 12,300 mph (19,800 kph), beginning the entry, descent and landing phase 11:49 a.m. PST (2:49 p.m. EST) — Peak heating of the protective heat shield reaches about 2,700°F (about 1,500°C) -15 seconds later — Peak deceleration, with the intense heating causing possible temporary dropouts in radio signals 11:51 a.m. PST (2:51 p.m. EST) — Parachute deployment -15 seconds later — Separation from the heat shield -10 seconds later — Deployment of the lander's three legs 11:52 a.m. PST (2:52 p.m. EST) — Activation of the radar that will sense the distance to the ground 11:53 a.m. PST (2:53 p.m. EST) — First acquisition of the radar signal -20 seconds later — Separation from the back shell and parachute -0.5 second later — The retrorockets, or descent engines, begin firing -2.5 seconds later — Start of the "gravity turn" to get the lander into the proper orientation for landing -22 seconds later — InSight begins slowing to a constant velocity (from 17 mph to a constant 5 mph, or from 27 kph to 8 kph) for its soft landing 11:54 a.m. PST (2:54 p.m. EST) — Expected touchdown on the surface of Mars 12:01 p.m. PST (3:01 p.m. EST) — "Beep" from InSight's X-band radio directly back to Earth, indicating InSight is alive and functioning on the surface of Mars No earlier than 12:04 p.m. PST (3:04 p.m. EST), but possibly the next day — First image from InSight on the surface of Mars No earlier than 5:35 p.m. PST (8:35 p.m. EST) — Confirmation from InSight via NASA's Mars Odyssey orbiter that InSight's solar arrays have deployed Get the peanuts ready, and let's land on Mars!  GO INSIGHT!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Parachute deployment is at Mach 1.66. What is Mach speed on Mars with air pressure and temperature so different than Earth's?

Depends on the things you described, but in general lower because of the vastly lower air density.

Standing by for X-band beep and maybe an image relayed by MarCO....
