At 2:47 pm ET, the entry, descent and landing phase is set to begin, and InSight will come blazing into the atmosphere at 12,300 miles per hour.
"There's a reason engineers call landing on Mars 'seven minutes of terror, '" added Rob Grover, InSight's entry, descent and landing (EDL) lead. The entry, descent, and landing phases will each emit a slightly different radio frequency, enabling engineers to track InSight's progress. Up to now, the success rate at the red planet was only 40 percent, counting every attempted flyby, orbital flight and landing by the U.S., Russian Federation and other countries since 1960.
But if you want to watch the landing with only audio from Mission Control, you can do that here.
"As it burns in the atmosphere, to slow down, it burns the heat shield, there will actually be a communications blackout, where the communications from the spacecraft will not be able to be received here on earth", NASA administrator Jim Bridenstine said.
According to NASA, it is the first outer space robotic explorer created to give the billions-years-old Mars a "thorough checkup" by studying its crust, mantle and core.
InSight also benefits from not being too picky about where it lands.
"While most of the country was enjoying Thanksgiving with their family and friends, the InSight team was busy making the final preparations for Monday's landing", said Tom Hoffman of JPL, InSight's project manager, in a statement released Sunday. Everything, from the angle at which the probe first hits the martian atmosphere, to the exact time its three legs pop free, ready to absorb the shock of landing, must go right - and in the right order. After streaking through space at some 12,300 miles per hour, the landing will kick off a billion-dollar mission to probe the red planet's hidden interior.
It was NASA's ninth attempt to land at Mars since the 1976 Viking probes. Let us know in the comments.
"It's taken more than a decade to bring InSight from a concept to a spacecraft approaching Mars - and even longer since I was first inspired to try to undertake this kind of mission", said Bruce Banerdt of JPL, InSight's principal investigator. Landing commentary includes interviews with team members.

It will take two to three months for InSight's robotic arm to set the mission's instruments on the surface.
So what do we know about the InSight robot, which is armed to the teeth with scientific instruments?
InSight landed on what seems to bea very boring part of Mars, known as Elysium Planitia. Because it won't be roving over the surface, the landing site was an important determination.
You may be wondering if InSight will meet native forms of life during its stay on Mars; alas, that question will remain unanswered. By carefully analyzing slight changes in the radio signals from the spacecraft as Mars rotates on its axis and sweeps along its orbit, scientists can precisely locate the martian polar axis and measure how it slowly changes orientation.
The Heat Flow and Physical Properties Probe (HP3) will compliment SEIS, using a self-hammering device to burrow down to a planned five meters below the surface-deeper than any digging on Mars before.
The lander will touch down on Mars at 3pm ET (8pm GMT), on Monday, November 26.
The 800-pound (360-kilogram) InSight is stationary and will operate from the same spot for the next two years, the duration of a Martian year.
It would be NASA's eighth landing on Mars.
