Read the Story
The solar arrays on NASA's InSight lander are deployed in this test inside a clean room at Lockheed Martin Space Systems, Denver. This configuration is how the spacecraft will look on the surface of Mars. The image was taken on April 30, 2015.

Meet InSight
A 3D model of NASA's InSight Mars lander.
NASA Visualization Technology Applications and Development (VTAD)
The lander was built on the proven design of
NASA's Mars Phoenix lander
. InSight's robotic arm was over 5 feet 9 inches (1.8 meters) long. It lifted a seismometer and heat flow probe from the deck and placed them on the surface.

Wind Sounds on Mars
InSight sensors captured a haunting low rumble caused by vibrations from the Martian wind, estimated to be blowing at 10 to 15 mph (5 to 7 meters a second) on Dec. 1, 2018. The winds were consistent with the direction of dust devil streaks in the landing area, which were observed from orbit.
Listen to Martian wind blow across NASA’s InSight lander.

Key Dates
Launched:
May 5, 2018 (4:05 a.m. PT/7:05 a.m. ET)
Launch Vehicle:
Atlas V-401
Launch Location:
Vandenberg Air Force Base, California
Landed:
Nov. 26, 2018, at 11:52:59 a.m. PT (2:52:59 p.m. ET)
Landing Site:
Elysium Planitia, Mars
End of Mission:
Dec. 15, 2022
Objective
The InSight mission had two major goals, each with several science investigations, designed to help uncover the process that shaped all of the rocky planets in the inner solar system.
Science
InSight studied the deep interior of Mars and was designed to take the planet's vital signs: its pulse, temperature, and reflexes.

Landing Site
Elysium Planitia
InSight landed near Mars' equator on the western side of a flat, smooth plain called Elysium Planitia. Elysium Planitia was selected not for its surface features, but for safety considerations. InSight's purpose was to study the interior of Mars, not the surface. Thus, in the selection of a landing site, what's on the surface mattered less than for previous rover missions focused on the geology.
Planitia is Latin for a flat surface, geometric plane, or flatness or a plain. Elysium is from the ancient Greek name for an afterlife paradise, usually referred to in English as the Elysian Fields. The landing site lies in the western portion of Elysium Planitia, centered at about 4.5 degrees north latitude and 135.9 degrees east longitude. This is just 373 miles (600 kilometers) from Curiosity’s landing site, Gale Crater.

Mars Cube One: The First Interplanetary Cubesats
The rocket that launched InSight also launched a separate NASA technology experiment: two mini-spacecraft called Mars Cube One, or MarCO. These briefcase-sized CubeSats flew on their own path to Mars behind InSight.
Engineer Joel Steinkraus uses sunlight to test the solar arrays on one of the Mars Cube One (MarCO) spacecraft.
