NASA’s InSight Lander Deploys Solar Panels after Surviving ‘7 Minutes of Terror’ Descent to Mars, Snaps 2nd Beautiful Photo

The Instrument Deployment Camera (IDC), located on the robotic arm of NASA's InSight lander, took this picture of the Martian surface on Nov. 26, 2018, the same day the spacecraft touched down on the Red Planet. The camera's transparent dust cover is still on in this image, to prevent particulates kicked up during landing from settling on the camera's lens.

CAPE CANAVERAL, FL  Mars newest resident, NASA’s InSight Lander, successfully deployed her twin solar arrays after surviving the harrowing ‘7 minutes of Terror’ descent through the planets thin atmosphere and safely soft landing on the smooth, vast expanse of the alien Red Planet locale named ‘Elysium Planitia’ – and snapped a second picture proving she was 'stayin alive'! 

“There’s a quiet beauty here. Looking forward to exploring my new home. #MarsLanding,” the InSight team tweeted along with that 2nd incredibly clear and beautiful photo shown above - late Monday evening, Nov. 26 on landing day. 

Thus far the mission has been a complete 100% success!!

The new photo - taken  by the robotic arm camera - shows the robotic arm and other instruments on the landers deck.  Unlike the first photo (see below) it’s not obscured by lots of dust thrown up during the landing despite also being protected by a transparent lens cap.

InSight’s mission is to study the deep interior of the fourth rock from the sun and unravel Mars and Earth evolution since they formed 4.5 Billion years ago.  

“Our Mars Odyssey orbiter phoned home, relaying news from @NASAInSight indicating its solar panels are open & collecting sunlight on the Martian surface. Also in the dispatch: this snapshot from the lander's arm showing the instruments in their new home,” NASA tweeted. 

Unfurling the power generating and life-giving solar wings was the next critical required step towards ensuring her survival for a planned 2 year mission - after completing the harrowing entry, descent and landing propulsive touchdown at 2:54  p.m. EDT, 11:54 a.m. PST, Monday, Nov 26. Thereby concluding a 7 month, 301 million mile (484 million km) interplanetary journey from Earth.

“Aaah...soaking up the Sun with my solar panels. After a long flight, and thrilling #MarsLanding, it feels great to get a good stretch and recharge my batteries. (Like, literally.) It’s just what I’ll need to really start getting in tune with #Mars.”

Confirmation that the solar panels deployed and were ‘catching the suns rays’ finally came some five and a half hour after touchdown via signals relayed by NASA's Mars Odyssey orbiter at about 8:30 p.m. EST  5:30 p.m. PST Monday, Nov. 26, 0130 Nov. 27 GMT, after it overflew InSight’s landing site.

“NASA's InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface,” NASA reported.

“NASA's Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight's landing site.”

"The InSight team can rest a little easier tonight now that we know the spacecraft solar arrays are deployed and recharging the batteries," said Tom Hoffman, InSight's project manager at NASA's Jet Propulsion Laboratory in Pasadena, California, which leads the mission, in a statement.

"It's been a long day for the team. But tomorrow begins an exciting new chapter for InSight: surface operations and the beginning of the instrument deployment phase."
NASA's InSight Mars lander acquired this image of the area in front of the lander using its lander-mounted, Instrument Context Camera (ICC). This annotated image was acquired on Nov. 26, 2018, Sol 0 of the InSight mission where the local mean solar time for the image exposures was 13:34:21. Each ICC image has a field of view of 124 x 124 degrees.  Credits: NASA/JPL-CalTech
InSight sports a wingspan of 19 feet 8 inches (6 meters) with solar panels deployed and a width of 5 feet 1 inch (1.56 meters) (lander deck diameter).

Each of the twin solar arrays are 7 feet (2.2 meters) wide.

On a clear Martian day the panels are estimates to provide about 600 to 700 -  enough to power a household blender and plenty to keep its instruments conducting science on the Red Planet, says the team.

“Even when dust covers the panels — what is likely to be a common occurrence on Mars — they should be able to provide at least 200 to 300 watts.”

Soon the team will unstow the robotic arm in preparation for placing the 2 international science instruments from Germany and France HP3 and SEIS - onto the surface after using camera images to select the best spots for safety and science gathering.

InSight in an international science mission. Loaded aboard are the two primary science instruments provided by European partners from France and Germany: The SEIS seismometer and  HP3 heat flow measuring instrument.

The SEIS seismometer instrument is equipped with a trio of incredibly precise seismometers to detect marsquakes and was provided by the Centre National d'Études Spatiales (CNES) - the French national space agency equivalent to NASA.  

The other instrument measuring heat flow from the Martian interior is provided by the German Aerospace Center (DLR) and is named Heat Flow and Physical Properties Package (HP3).  

The HP3 hammering mole will pound about 5 meters (16 feet) deep into Mars pulling the science heat flow cable tether along to make heat flow and temperature measurements.   It will pause multiple times along the way down to make detailed measurements at different depths of heat flow from the planets core. 

Meanwhile one of the briefcase sized Mars Cube One (MarCO) minisatellites which transmitted all the real time EDL data on landing day Monday, also snapped a farewell photo- see below from MarCO-B.
MarCO-B, one of the experimental Mars Cube One (MarCO) CubeSats, took this image of Mars from about 4,700 miles (6,000 kilometers) away during its flyby of the Red Planet on Nov. 26, 2018. MarCO-B was flying by Mars with its twin, MarCO-A, to attempt to serve as communications relays for NASA’s InSight spacecraft as it landed on Mars.  Credits: NASA/JPL-Caltech


Instead of over 5 hours from Mars Odyssey, it took only 8.1 minutes from MarCO, the time it takes for radio signals traveling at light speed from Mars to Earth across a distance of 91 million miles (146 million kilometers).

The pair traveled to Mars along with but separately from InSight following launch from Earth on a ULA Atlas V rocket 7 months ago.

InSight is NASA’s first mission to Mars surface in 6 years since the Curiosity rover safely touched down by the skycrane maneuver in 2012 - to begin a minimum 2 year long mission to study the heart of Mars and elucidate the deep interior of the Red Planet like never before. 

The landing location at Elysium Planitia just north of the equator is about 340 miles (550 kilometers) away from Gale Crater - where NASA's Curiosity rover landed in 2012. 
Elysium Planitia, a flat-smooth plain just north of the equator makes for the perfect location from which to study the deep Martian interior.  The landing site is centered at about 4.5 degrees north latitude and 135.9 degrees east longitude.

InSight, which stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport,  is designed to study the deep interior of Mars.  

The $850 million seeks the fingerprints of the processes that formed the rocky planets of the solar system. 

InSight is funded by NASA’s Discovery Program of low cost, focused science missions along with the science instrument funding contributions from France and Germany.
