LOS ANGELES, Nov. 26 (Xinhua) -- NASA's InSight spacecraft touched down safely on Mars on Monday, kicking off its two-year mission as the first spacecraft designed to explore the deep interior of another world.

Launched on May 5, InSight marks NASA's first landing on Mars since the Curiosity rover in 2012 and the first dedicated to studying the deep interior of the red planet.

NASA's online live broadcast reported InSight touched down on Mars at approximately 2:54 p.m. EST (1954 GMT) on Monday, after a six-month, 300-million-mile (480-million-km) journey.

The lander plunged through the thin Martian atmosphere at about 2:47 p.m. EST (1947 GMT), heatshield first, and used a supersonic parachute to slow down. Then, it fired its retro rockets to slowly descend to the surface of Mars, and landed on the smooth plains of Elysium Planitia.

The landing took just under seven minutes to complete, prompting the nickname "seven minutes of terror."

InSight is being followed to Mars by two mini-spacecraft comprising NASA's Mars Cube One (MarCO), the first deep-space mission for CubeSats which attempt to relay data from InSight as it enters the planet's atmosphere and lands.

At about 3 p.m. EST (2000 GMT), MarCO sent back the first picture of Mars.

The photo is speckled with black dots - probably particles of dust picked up during InSight's harrowing descent through the Martian atmosphere, said Rob Manning, chief engineer at NASA's Jet Propulsion Laboratory (JPL).

Future InSight images will be much clearer, after the camera's dust cover is removed, he added.

InSight will detect geophysical signals deep below the Martian surface, including marsquakes and heat. Scientists will also be able to track radio signals from the stationary spacecraft, which vary based on the wobble in Mars' rotation, according to NASA.

InSight and MarCO flight controllers monitored and cheered for the spacecraft's successful entry, descent and landing from mission control at JPL in Pasadena, California.

"Today, we successfully landed on Mars for the eighth time in human history," said NASA Administrator Jim Bridenstine at a post landing press briefing .

"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," he said. "The best of NASA is yet to come, and it is coming soon."

A number of European partners, including France's Centre National d'Études Spatiales (CNES) and the German Aerospace Center (DLR), support the InSight mission.

CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument, and DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, Bridenstine said.

It took the InSight team about four to five years to design and execute the mission, said InSight project manager Tom Hoffman

He said the basic design of InSight was inherited from Phoenix spacecraft, which landed on Mars on May 25, 2008.

To look deep into Mars, the lander must be at a place where it can stay still and quiet for its entire mission. That's why scientists chose Elysium Planitia as InSight's home, according to NASA.

The red planet is comparatively easy to land on and is less likely to melt our equipment than Venus or Mercury, according to NASA.
