NASA's Mars InSight lander set for nail-biting touchdown on the red planet
This will be the space agency's first attempt at landing on Mars since the Curiosity rover in 2012.

After a roughly 300-million-mile journey lasting more than six months, a new NASA probe is set to touch down on Mars next week, beginning a two-year mission to peer deep inside the red planet’s interior.

The   Mars InSight lander , which launched into space in May from Vandenberg Air Force Base in California, is scheduled to touch down just north of the Martian equator around 3 p.m. EST on Nov. 26. You can   watch the landing live on NASA TV   starting at 2 p.m. EST.

This will be NASA’s first attempt at landing on Mars since the space agency’s   Curiosity rover   pulled off its own nail-biting landing in 2012 — a feat NASA characterized at the time as “seven minutes of terror.”

Unlike the Curiosity rover, Insight won’t be able to move about on Mars. But using a suite of instruments and a seven-foot-long robotic arm, it will drill up to 16 feet below the surface at its landing site, Elysium Planitia, a broad plain that has been called   “the biggest parking lot on Mars.”

Having a big target makes things a bit easier, but it doesn’t mean the landing will succeed. NASA has lost Mars-bound spacecraft before, including the Mars Polar Lander in December 1999, and a complex sequence of steps must go right for the touchdown to be successful.

About seven minutes before it reaches the top of Mars' atmosphere, the InSight lander will be released from the spacecraft that ferried it to Mars. Ensconced inside its heat-protecting “aeroshell” capsule, the 800-pound lander will descend 70 miles through the thin Martian atmosphere for about six minutes. Then, a supersonic parachute and a series of descent engines will slow the spacecraft before it touches down on shock-absorbing legs.

The InSight lander will be the   first to study the red planet’s deep interior . The goal is to compare the interior of Mars to that of Earth so that scientists can better understand how these rocky worlds formed more than 4.5 billion years ago.

In addition to its drill-tipped robotic arm, the lander is equipped with a seismometer and thermometer designed to measure the   frequency and magnitude of marsquakes   and show how heat from deep inside Mars makes its way to the surface.

The InSight lander isn’t designed to search for life, but NASA says it could show whether microbes do, or ever did, live beneath the surface. The agency is planning to launch a new rover to Mars in 2020 that will look for signs of past microbial life on the red planet.

Although not the point of this mission, the nerd inside of me is looking forward to life, even simple life, being found on this mission.

Even simple bacteria would be a helluva find

That would be an awesome and monumental find.

The fantasies that I was imagining while reading Science Fiction pulp magazines and novels (Arthur C. Clark, Robert Heinlein, Ray Bradbury, "Doc" Edward E. Smith, etc) in the 1950s, such as about exploring Mars, are in fact happening these days. These new space adventures would certainly amaze those who had laughed at H. G. Wells and Jules Verne. Now if someone would only invent a time machine.....

I was watching something the other night about the insight lander that indicated

that the last 15 missions to Mars have failed , many mysteriously and especially while orbiting the far side of the planet

where they are not in direct contact with earth.

The Russians quit sending probes to Mars in frustration after another launch failure in 2011

Landing a probe on Mars is harder than most probably realize. It might be more difficult than sending probes accurately enough to reach and study the outer planets.
