NASA is counting all the way down to a nail-biting landing Monday of the $993 million Mars InSight, the primary spacecraft to pay attention for quakes and research the interior workings of one other rocky planet.

Nobody is on board the spacecraft, which launched almost seven months in the past and has traveled some 300 million miles (482 million kilometers).

However a part of its mission is to tell efforts to in the future ship human explorers to the Crimson Planet, which NASA hopes to do by the 2030s.

The lander is the primary to achieve Mars since 2012, when NASA’s Curiosity rover touched all the way down to scour the floor and analyze rocks for indicators that life types could as soon as have inhabited Earth’s neighbor, now a frigid and dry planet.

InSight should survive tense entry into Mars’ environment, touring at a velocity of 12,300 miles (19,800 kilometers) per hour and swiftly slowing to simply 5 mph (eight kph).

This entry, descent and touchdown section begins at 11:47 am in California (1947 GMT) — and is barely half-jokingly referred to at NASA as “Six and a Half Minutes of Terror.”

Of 43 missions launched towards Mars, solely 18 have made it intact — successful fee of round 40 %. All people who made it got here from the USA.

“Going to Mars is admittedly, actually onerous,” mentioned Thomas Zurbuchen, affiliate administrator for the NASA science mission directorate.

“The thrilling half is we’re constructing on the success of the very best staff that has ever landed on this planet, which is the NASA staff with its contractors and its collaborators.”

The identify InSight is derived from “Inside Exploration utilizing Seismic Investigations, Geodesy and Warmth Transport.”

The spacecraft itself stands about waist excessive, at 3.5 toes (one meter), and as soon as its photo voltaic arrays are deployed they may span 20 toes.

Totally fueled, InSight weighs greater than 800 kilos (360 kg), about the identical as a Harley Davidson bike.

Its central instrument is a quake-sensing seismometer that was made by the French Area Company (CNES).

“That is the one NASA mission till now which is conceived round a foreign-made instrument,” Jean-Yves Le Gall, president of CNES, instructed AFP.

“So it is a mission that’s basically for the USA, for France and for bettering our understanding of Mars.”

The six quake sensors on board are so delicate they need to reveal the smallest tremors on Mars, such because the faint pull of its moon Phobos, impacts from meteors, and presumably proof of volcanic exercise.

Seismology has taught humanity a lot concerning the formation of Earth some 4.5 billion years in the past, however a lot of the Earth-based proof has been misplaced to the recycling of the crust, pushed by plate tectonics. This course of does not exist on Mars.

The spacecraft additionally has a self-hammering probe that may burrow as deep as 10-16 toes (3-5 meters), providing the primary exact measurement of below-ground temperatures on Mars and the way a lot warmth escapes from its inside.

– Touchdown situations –

InSight was constructed by Lockheed Martin, and is modeled after the Phoenix spacecraft that landed close to the Martian north pole in 2008.

Like Phoenix, InSight’s arrival will probably be aided by a parachute. Its warmth protect will assist decelerate the spacecraft and shield towards the new friction of coming into Mars’ environment.

Its touchdown web site is flat space known as Elysium Planitia, which NASA has known as “the most important parking zone on Mars.”

The lander should set itself down upright. After which, one other essential step is for the photo voltaic arrays to deploy, for the reason that lander’s one-year mission will probably be absolutely solar-powered.

NASA ought to know inside minutes if the touchdown went effectively or not, however must wait greater than 5 hours for affirmation of the photo voltaic array deployment, as a result of orbit sample of the Mars Reconnaissance Orbiter and Mars Odyssey which might talk InSight’s standing again to Earth.

That first confirming ping at 2004 GMT Monday is eagerly awaited by the crew at mission management at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“I do have a variety of blood sweat and tears invested on this, and I’m trying ahead to a pleasant, protected landing on Monday,” mentioned Stu Spath, InSight program supervisor at Lockheed Martin.
