NASA’s InSight Mars Lander made historical past when it touched down on the Crimson Planet in late November — the eighth profitable touchdown on Mars since 1976. It joined NASA’s car-sized Curiosity rover, which has made some attention-grabbing finds because it arrived on the planet in August 2012.

And even minutes after it landed on Martian sand, the InSight Lander was already attending to work. Prior to now week, it has checked a number of duties off its to-do listing.

“I landed on #Mars every week in the past in the present day. Right here’s what I’ve been as much as to date: Snap first photos, Open photo voltaic panels, Verify well being standing, Energy on devices, Take preliminary science knowledge for calibration,” NASA tweeted on Dec. four from an account devoted to the InSight Lander’s mission. The account famous it nonetheless needed to prolong its arm and take footage of the deck.

It could not sound like a lot now, however the InSight Lander’s journey is simply starting. Here is what the spacecraft has achieved to date.

Surviving “7 minutes of terror”

The three-legged InSight settled on the western facet of Elysium Planitia, the plain that NASA was aiming for on Nov. 26.

After six months, touring 300 million miles at speeds as much as 12,000 mph, the InSight Lander made its manner into Mars’ environment — however it wasn’t a simple job.

“There is a cause engineers name touchdown on Mars ‘seven minutes of terror,'” Rob Grover, InSight’s entry, descent and touchdown (EDL) lead, based mostly at NASA’s Jet Propulsion Laboratory in Pasadena, California, mentioned in a assertion. “We will not joystick the touchdown, so we’ve got to depend on the instructions we pre-program into the spacecraft. We have spent years testing our plans, studying from different Mars landings and learning all of the circumstances Mars can throw at us.”

On Nov. 26 at three p.m. ET the InSight Lander efficiently accomplished its “mushy landing.”

“Landing confirmed!” a flight controller referred to as out to fellow NASA workers.


Due to the space between Earth and Mars, it took eight minutes for affirmation to reach, relayed by a pair of tiny satellites that had been trailing the spacecraft.

“Flawless,” declared JPL’s chief engineer, Rob Manning. “Generally issues work out in your favor.”

First images

Simply minutes after it landed on Mars’ sandy floor, the 800-pound Perception Lander had already despatched again “good and soiled” photos to the area station. Hours later, the spacecraft despatched a clearer picture of its environment.

These photos had been only the start of what the spacecraft is anticipated to seize throughout its $1 billion worldwide mission on the Crimson Planet.

Per week later, NASA blasted Twitter with gorgeous photos from the planet’s Martian floor at Elysium Planitia, the lava plain the place the InSight Lander parked on.


“Increase your hand in the event you’re on this new picture from #Mars!” NASA wrote in a Dec. 6 tweet. “These two tiny chips include the names of greater than 2.four million individuals who signed as much as fly with me. We’re ON MARS, you guys. You’re all honorary Martians!”

Hours later that very same day, NASA added, “One step at a time… Now that I’ve received my arm out, I can begin making an in depth 3D map of my workspace, the realm proper in entrance of me the place I’ll place my devices. Right here’s extra on what I’ve been doing, and what’s but to come back.”

“I don’t wish to brag, however inform me once you’ve ever seen a prettier photo voltaic panel,” NASA then joked.

Bruce Banerdt, the mission’s principal investigator at NASA’s Jet Propulsion Laboratory (JPL) in California, mentioned area lovers can count on extra photos to be launched in mid-December.

“By early subsequent week (Dec. 10-15), we’ll be imaging it in finer element and making a full mosaic,” Banerdt mentioned in an internet assertion.


One other digicam referred to as the Instrument Context Digicam on the Perception Lander may even present views of the spacecraft’s “workspace.”

“We had a protecting cowl on the Instrument Context Digicam, however by some means mud nonetheless managed to get onto the lens,” Tom Hoffman of JPL, InSight’s challenge supervisor, mentioned in a press release. “Whereas that is unlucky, it won’t have an effect on the function of the digicam, which is to take photos of the realm in entrance of the lander the place our devices will finally be positioned.”

“Listening to” Martian winds

NASA’s new Mars lander has captured the primary sounds of the Martian wind.

The Jet Propulsion Laboratory launched audio clips of the alien wind on Dec. 7. The low-frequency rumblings had been collected by the InSight lander throughout its first week-and-a-half of operations on Mars.

“Capturing this audio was an unplanned deal with,” Banerdt mentioned in an internet assertion. “However one of many issues our mission is devoted to is measuring movement on Mars, and naturally that features movement brought on by sound waves.”

Scientists agree the sound has an otherworldly high quality to it, they usually really feel as if they’re sitting on the spacecraft.

The noise is of the wind blowing in opposition to InSight’s photo voltaic panels and the ensuing vibration of all the spacecraft. The sounds had been recorded by an air strain sensor contained in the lander that is a part of a climate station, in addition to the seismometer on the deck of the spacecraft.

“The InSight lander acts like an enormous ear,” Tom Pike, InSight science crew member and sensor designer at Imperial School London, added in a press release. “The photo voltaic panels on the lander’s sides reply to strain fluctuations of the wind. It is like InSight is cupping its ears and listening to the Mars wind beating on it. After we appeared on the course of the lander vibrations coming from the photo voltaic panels, it matches the anticipated wind course at our touchdown web site.”
