NASA’s Insight Lander Snaps 1st Selfie on Red Planet

CAPE CANAVERAL, FL  NASA’s newest probe on Mars - the InSight lander – has snapped its first selfie on the Red Planet and its truly eyepopping – showing virtually the entire robot in all its glory including the science and weather instruments on the deck and the twin solar panels spreading out on each side looking like circular fans. 

“NASA's InSight lander isn't camera-shy,” announced NASA in a press release accompanying the selfie mosaic on Dec 11.

“First #selfie! I’m feeling healthy, energized and whole. This is me on #Mars,” the robot tweeted about herself. 

The selfie is comprised of a mosaic of 11 images taken on Dec. 6, 2018 (Sol 10) taken by one of two on board cameras – namely the IDD or Instrument Deployment Device, and assembled together by the science and engineering team.

The two week old lander looks quite beautiful sitting atop the Elysium Planitia  landing site specifically selected to be boring as possible – it’s a smooth flat plain with as few rocks as possible because top priority was to land safely.  

Unlike all of NASA’s previous robotic Martian rovers and landers InSight’s mission is to dig deep beneath the Red Planets surface to listen for the heartbeat of the Red Planet -  rather than survey and investigate rocks and soils above or just below the surface.  

"The near-absence of rocks, hills and holes means it'll be extremely safe for our instruments," said InSight's Principal Investigator Bruce Banerdt of NASA's Jet Propulsion Laboratory in Pasadena, California, in a statement. 

"This might seem like a pretty plain piece of ground if it weren't on Mars, but we're glad to see that."

“InSight's landing team deliberately chose a landing region in Elysium Planitia that is relatively free of rocks. Even so, the landing spot turned out even better than they hoped. The spacecraft sits in what appears to be a nearly rock-free "hollow" — a depression created by a meteor impact that later filled with sand.”

The team says that that’s really advantageous for one of InSight's instruments, the German supplied heat-flow probe (HP3) , since it should be easier for it to accomplish its goal to bore down about  16 feet (5 meters) below the surface.

Along with the selfie, the team also released a mosaic showing the first complete look of  the workspace in front of the lander where InSight will use its robotic arm to deploy its two main instruments over the next few months - namely HP3 and SEIS.

The crescent shaped terrain is nearly devoid of rocks and measures approximately 14-by-7-foot (4-by-2-meter). 

The workspace mosaic is composed of 52 individual photos.

“In the coming weeks, scientists and engineers will go through the painstaking process of deciding where in this workspace the spacecraft's instruments should be placed,” says the InSight team. 

“They will then command InSight's robotic arm to carefully set the seismometer (called the Seismic Experiment for Interior Structure, or SEIS) and heat-flow probe (known as the Heat Flow and Physical Properties Package, or HP3) in the chosen locations. Both work best on level ground, and engineers want to avoid setting them on rocks larger than about a half-inch (1.3 cm).”

InSight soft landed on Mars barely two weeks ago on Nov 26, 2018, following a 7 month, 301 million mile (484 million km) interplanetary journey from Earth. She now starts a 2-year mission to explore the Red Planet’s mysterious deep interior.
