NASA's InSight Lander Just Sent This Picture From The Surface Of Mars

Not a bad first effort.

NASA’s Mars science lander InSight touched down safely on the surface of the Red Planet on Monday to begin its two-year mission as the first spacecraft designed to explore the deep interior of another world.

Engineers at the Jet Propulsion Laboratory (JPL) near Los Angeles burst into cheers and applause as they received signals confirming InSight’s arrival on Martian soil - a vast, barren plain near the planet’s equator - shortly before 3pm EST.

Minutes later, JPL controllers received a fuzzy photograph of the probe’s new surroundings on the Red Planet, showing the edge of one lander leg beside a rock.

NASA's InSight Mars lander acquired this image of the area in front of the lander using its lander-mounted, Instrument Context Camera (ICC) with the ICC image field of view of 124 x 124 degrees,.

The landing data and first image were relayed to Earth from one of two miniature satellites that were launched along with InSight and were flying past Mars as it reached its destination.

Later it sent a far more detailed selfie, posted on its Twitter account.

There’s a quiet beauty here. Looking forward to exploring my new home. #MarsLanding pic.twitter.com/mfClzsfJJr

The landing capped a six-month journey of 301 million miles (548 million km) from Earth, following InSight’s launch from California in May.

Carrying instruments that detect planetary heat and seismic rumblings never measured anywhere else but Earth, the stationary lander streaked into the thin Martian atmosphere at 12,300 miles (19,795 km) per hour.

Its 77-mile descent was then slowed by atmospheric friction, a giant parachute and retro rockets, bringing the three-legged spacecraft to a gentle landing within seven minutes.

Once landed, the stationary probe was programmed to pause for 16 minutes for the dust to settle, literally, around its landing site, before two disc-shaped solar panels were to be unfurled like wings to provide power to the spacecraft.

But scientists did not expect to verify successful deployment of the solar arrays for at least several hours.

The 880-pound (360 kg) InSight - its name is short for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport - marks the 21st US-launched Marsmission, dating back to the Mariner fly-bys of the 1960s. Nearly two dozen other Mars missions have been sent from other nations.

InSight’s new home in the middle of Elysium Planitia, a wide, relatively smooth expanse close to the planet’s equator, is roughly 373 miles (600 km) from the 2012 landing spot of the car-sized Mars rover Curiosity, the last spacecraft sent to the Red Planet by NASA.

PEERING BENEATH SURFACE

InSight will spend 24 months - about one Martian year - collecting a wealth of data to unlock mysteries about how Mars formed and, by extension, the origins of the Earth and other rocky planets of the inner solar system.

While Earth’s tectonics and other forces have erased most evidence of its early history, much of Mars - about one-third the size of Earth - is believed to have remained largely static, creating a geologic time machine for scientists.

InSight’s primary instrument is a French-built seismometer, designed to record the slightest vibrations from “marsquakes” and meteor impacts around the planet. The device, to be placed on the surface by the lander’s robot arm, is so sensitive it can measure a seismic wave just one half the radius of a hydrogen atom.

Good Morning America

Scientists expect to see a dozen to 100 marsquakes during the mission, producing data to help them deduce the depth, density and composition of the planet’s core, the rocky mantle surrounding it, and the outermost layer, the crust.

The NASA Viking probes of the mid-1970s were equipped with seismometers, too, but they were bolted to the top of the landers, a design that proved largely ineffective.

Apollo missions to the moon brought seismometers to the lunar surface as well. But InSight is expected to yield the first meaningful data on planetary seismic tremors beyond Earth.

A second instrument, furnished by Germany’s space agency, consists of a drill to burrow as much as 16 feet (5 meters) underground, pulling behind it a rope-like thermal probe to measure heat flowing from inside the planet.

Meanwhile, a radio transmitter will send back signals tracking Mars’ subtle rotational wobble to reveal the size of the planet’s core and possibly whether it remains molten.

NASA officials say it will take two to three months for the main instruments to be deployed and put into operation.

InSight and the next Mars rover mission, scheduled for 2020, along with others in the planning stage, are seen as precursors for eventual human exploration of Mars, NASA officials said.
