CAPE CANAVERAL, FL  Congratulations InSight !!! NASA’s newest Mars mission the Insight Lander sticks flawless Mars landing just moments ago at 2:54  p.m. EDT, 11:54 a.m. PST, following a 7 month, 301 million mile (484 million km) interplanetary journey from Earth - and now starts a 2-year mission to explore the Red Planet’s mysterious deep interior.

"Touchdown confirmed,” reported Christine Szalia of mission control at NASA’s Jet Propulsion Laboratory, Pasadena, CA, live on NASA TV webcast.

"InSight is on the surface of Mars!!”

Louds cheering and boisterous applause erupted immediately at JPL, throughout NASA and worldwide at the fantastic success and reality of InSight becoming NASA’s 8th mission to successfully touchdown on Mars.  

“This is really fabulous,” said JPL’s chief engineer Rob Manning offering commentary on the webcast.  He has worked on all of NASA’s Mars landers and rovers for more than 20 years going back to Mars Pathfinder in the 1990s.

"Flawless!Everything we hoped for!”

Now resting safely on the surface of the Red Planet,  InSight can now begin at an alien locale called ‘Elysium Planitia’ InSight can now move forward to start her studies of the heart of Mars and its deep interior for the first time in human history.

InSight is the first mission to drill down deep below the surface and explore Mars deep interior.  All prior missions have scratched the surface of the fourth rock from the Sun by design for rock and soli samples. Now we go deep !! - to listen for Marsquakes and measure heat flow emanating from far below!  

"It was intense. And you could feel the emotion," said NASA Administrator Jim Bridenstine, at the JPL briefing. 

"It was very, very quiet when it was time to be quiet and of course very celebratory with every little new piece of information that was received. It's very different being here than watching it on TV, by far, I can tell you that for sure now that I've experienced both." 

InSight survived all the treachery and blazing temperatures of the ‘7 Minutes of Terror’!!

The $830  million spacecraft slammed into the top of Martian atmosphere at over 12,300 miles per hour (5.5 kilometers per second, 19,800 kph) and approximately 80 miles (about 128 kilometers)  altitude at around 2:47 p.m. EST, 11:47 a.m. PST and experienced blazes temperatures reaching up to 2700 degrees F (1500 C) – enough to melt steel – while protected from melting and utter destruction by the advanced heat shield.  

"We spend most of our time visualizing all these bad things that can happen, but sometimes things work out in your favor," said Manning.  "It certainly looked like it was a very successful and perfect landing."

Ultimately InSight used a preprogrammed series of maneuvers and operated autonomously throughout all of EDL EDL (Entry, Descent and Landing) with the heat shield, a supersonic parachute and 12 landing thrusters in succession to slow her descent to about 5 MPH (8 kph) at touchdown – brilliantly concluding the harrowing ‘7 Minutes of Terror’ at approximately 2:54  p.m. EDT, 11:54 a.m. PST.

And just moments later NASA’s InSight transmitted her first post touchdown photo from the surface of the Red Planet at the landing site named Elysium Planitia – a sandy, flat plain with few rocks and chosen because it offered the best chances for a successful landing and science gathering.

The fisheye camera is covered by a dust cover accounting for the dusty image - that will soon be released to provide a crystal clear view of the landing site. 

“Our @NASAInSight spacecraft stuck the #MarsLanding!" 

"Its new home is Elysium Planitia, a still, flat region where it’s set to study seismic waves and heat deep below the surface of the Red Planet for a planned two-year mission,” NASA tweeted along with the 1st photo.

“Congratulations to @NASA, @LockheedMartin, @ulalaunch, & all who made today's @NASAInSight #MarsLanding possible! This marks the 8th time the US has landed on Mars & the 1st mission to study its deep interior. Incredible milestone!” tweeted VP Mike Pence who called the team with congratulations seconds after the  successful landing.

NASA Administrator Jim Bridenstine attended the landing events at JPL and spoke and tweeted congratulation to the entire InSight team, all of the NASA family and space enthusiasts: 


"Today, we successfully landed on Mars for the eighth time in human history,” said NASA Administrator Jim Bridenstine. “InSight will study the interior of Mars, and will teach us valuable science as we prepare to send astronauts to the Moon and later to Mars. This accomplishment represents the ingenuity of America and our international partners and it serves as a testament to the dedication and perseverance of our team. The best of NASA is yet to come, and it is coming soon.”
Although NASA’s Mars Odyssey (MO) and Mars Reconnaissance Orbiter (MRO) Red Planet orbiters are the primary communications relays for InSight neither could be in place at the moment of landing to transmit real time data back to anxious engineers on Earth monitoring the health and status of InSight during the descent.

Thus NASA decided to send a pair of tiny experimental cubesats to carry out that critical chore- namely MarCO A and MarCO B.

And they performed marvelously !!  Otherwise we would have had to had more than 5 hours to learn InSights fate. 

Instead it took only 8.1 minutes – 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).

Confirmation of InSight’s successful touchdown and receipt of the terrific 1st photo came via the1st ever interplanetary cubesats which relayed the critical data in realtime- namely the pair of briefcase sized Mars Cube One (MarCO) minisatellites which traveled to Mars along with but separately from InSight following launch from Earth on a ULA Atlas V rocket 7 months ago.

Seconds later the two MarCO’s passed out of range as they continued flying past Mars. 


Together they had made an interplanetary trek of 301 million mile (484 million km) from Earth.


The next critical step is solar array deployment to provide life giving power to the planned two year long mission. 


Conformation should come in a few hours.

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. 
The Mars Odyssey orbiter took this image of the target landing site for NASA's InSight lander at flat-lying Elysium Planitia, centered at about 4.5 degrees north latitude and 136 degrees east longitude. The landing ellipse covers an area within which the spacecraft has about 99 percent chance of landing when targeted for the center of the ellipse. It is about 81 miles (130 kilometers) long, generally west to east, and about 17 miles (27 kilometers) wide. Credits: NASA/JPL-Caltech/ASU
Engineer’s conducted a final Trajectory Correction Maneuver known as TCM-6 late Sunday afternoon, Nov 25 to aim InSight more precisely to the center of the landing ellipse – hoping to shift it about 10 miles west from what TCM-5 accomplished. 

The spacecraft is on course to study Mars deep interior and Marsquakes for the first time in human history to elucidate how it evolved over 4.5 Billions years.  That history has been erased by natural progression and evolution on and inside Earth including plate tectonics and erosion of our planet's crust.  


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 to detect marsquakes 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. 

Other contributions came from Switzerland, Great Brittan and Poland. 

After landing it will take about 2 to 3 months to carefully lift the two science instruments off the robots deck and deploy them onto Mars surface using the robotic arm.

InSight is equipped with two cameras.  One just below the rover deck is a fisheye. The other called IDD  is a color located at the terminus of the robotic arm – similar to Phoenix. 

The team will use the cameras to carefully and methodically selected the best spot for the instruments deployments. 

The instruments deployments will be deployed to the surface with a 7 foot long (2 m) robotic arm. 

There is also a weather station aboard to continuously measure Mars local temperatures, wind speeds and direction and pressures every day 24/7 for the first time on Mars.

The spacecraft is based on the design of NASA’s successful Mars lander which touched down safely back in 2008 which arrived at a slightly faster velocity of 12,500 miles per hour (5.6 kilometers per second).

Insight is also slightly heavier weighing about 1,340 pounds (608 kilograms) vs. 1,263 pounds (573 kilograms) when it slams into the atmosphere.


InSight also will be landing at a slightly higher elevation of “about 4,900 feet (1.5 kilometers) higher than Phoenix did, so it has less atmosphere to use for deceleration.”


The InSight team has been busy for 7 years to get the spacecraft ready – and the fruits of their labor was harvested with today’s spectacularly successful landing.


The landed probe has a mass of 794 pounds (360 kilograms). It 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).

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.
