The thee-legged, one-armed InSight will operate from the same spot for the next two years. With a host of scientific instruments on board, the lander will study the Red Planet's interior, gathering groundbreaking data about Mars' composition and how tectonically active the planet is.
Congratulations flooded into the space agency following the success, including from Mike Pence, the U.S. vice president, who celebrated the "incredible milestone" of the country's eighth successful landing on Mars.
The NASA Viking probes of the mid-1970s were equipped with seismometers, too, but they were bolted to the top of the landers, a design that proved largely ineffective.
InSight robotically guided itself through the landing, outside of a few last minute tweaks by the entry, descent and landing team to the algorithm that guides the lander to the surface.
The robotic will slow down from 12,300 miles per hour to zero in six minutes flat as it pierces the Martian atmosphere, pops out a parachute, fires its descent engines and, hopefully, lands on three legs.
Tom Hoffman, InSight Project Manager, NASA JPL talks about the Mars InSight landing site during a pre-landing briefing today. NASA's next mission, the Mars 2020 rover, will prowl for rocks that might contain evidence of ancient life.
InSight had a six-minute window in which to decelerate from just under 13,000mph to 5mph - landing entirely based on autonomous and pre-programmed systems.

Shares of Amazon .com Inc, Alphabet Inc and Facebook Inc rose more than 2 percent, while shares of Apple Inc edged up 0.6 percent. Japan's benchmark Nikkei 225 dropped 0.4 percent and the Kospi in South Korea was down 0.3 percent.
Once on Mars, InSight will drill into the ground with a probe to offer mankind a first-ever look inside the Red Planet. NASA administrator Jim Bridenstine said the device could detect how often Mars gets bombarded by asteroids. Up until now, the success rate at the red planet has been only 40 per cent, counting every attempted fly-by, orbital flight and landing by the US, Russia and other countries since 1960. While it'll be some time before that happens, space enthusiasts have something to analyze in the interim: InSight's first photograph of Mars, which can be seen below.
But on Tuesday afternoon, we may get the first image back from InSight of its new home on the surface of Mars.
Three of InSight's seismic instruments were designed and built in Britain.
The smaller, 360kg InSight- its name is short for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport-marks the 21st US-launched Mars mission, dating back to the Mariner fly-bys of the 1960s. InSight also has an experiment (Rotation and Interior Structure Experiment, or RISE) that will precisely measure the planet's "wobble" to reveal the size and density of the Martian core.
The first is a package of Franco-British seismometers that will be lifted on to the surface to listen for "Marsquakes".
NASA officials say it will take 2 to 3 months for the main instruments to be deployed and put into operation.
"MarCO was there to relay information back from InSight in real time, and we did that extraordinarily well", said Andy Klesh, MarCO chief engineer, at a press conference at the Jet Propulsion Laboratory here November 26 two hours after the InSight landing.
