NASA’s InSight Collecting Sunlight on The Martian Surface

InSight will operate on the surface for one Martian year, plus 40 Martian days, or sols, until November 24, 2020. The mission objectives of the two small MarCOs which relayed InSight's telemetry was completed after their Martian flyby

After the successful launch of NASA’s InSight on Mars on Monday, the spacecraft has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface.

NASA’s Mars Odyssey spacecraft, that is currently orbiting the Red Planet, relayed the signals. It was received on Earth at about 5.30 p.m. PST (8.30 p.m. EST), the US space agency said in a statement.

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.

“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,” Hoffman added.

On Monday, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet after an almost seven-month, 300-million-mile (458-million-kilometre) journey from Earth.

InSight was launched from Vandenberg Air Force Base in California on May 5. The lander touched down on Monday, near Mars’ equator on the western side of a flat, smooth expanse of lava called Elysium Planitia, with a signal affirming a completed landing sequence at approximately noon PST (3 p.m. EST).

The spacecraft’s two-year mission will be to study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed, NASA said.

InSight’s twin solar arrays are each seven feet (2.2 meters) wide when they’re open, the entire lander is about the size of a big 1960s convertible. Mars has weaker sunlight than Earth because it’s much farther away from the Sun.

But the lander doesn’t need much to operate: The panels provide 600 to 700 watts on a clear day, enough to power a household blender and plenty to keep its instruments conducting science on the Red Planet. 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.

“We are solar powered, so getting the arrays out and operating is a big deal. With the arrays providing the energy we need to start the cool science operations, we are well on our way to thoroughly investigate what’s inside of Mars for the very first time,” Hoffman said.

The panels are modelled on those used with NASA’s Phoenix Mars Lander, though InSight’s are slightly larger in order to provide more power output and to increase their structural strength. These changes were necessary to support operations for one full Mars year (two Earth years).

In the coming days, the mission team will unstow InSight’s robotic arm and use the attached camera to snap photos of the ground so that engineers can decide where to place the spacecraft’s scientific instruments. It will take two to three months before those instruments are fully deployed and send back data, NASA said.

In the meantime, InSight will use its weather sensors and magnetometer to take readings from its landing site at Elysium Planitia — its new home on Mars.

With InSight landing successfully on Mars on Monday, NASA has successfully soft-landed a vehicle on the Red Planet eight times, the statement noted.

“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,” he added.

InSight will begin to collect science data within the first week after landing, though the teams will focus mainly on preparing to set InSight’s instruments on the Martian ground. At least two days after touchdown, the engineering team will begin to deploy InSight’s 5.9-foot-long (1.8-meter-long) robotic arm so that it can take images of the landscape.

Anticipated Problems That May Effect NASA’s Mars Mission

According to results from the first eight analog space crews, presented at the American Association for the Advancement of Science (AAAS) annual meeting in Washington, D.C., the astronauts are able to successfully complete tasks between 20 and 60 per cent of the time.

Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and tick off problems that may make or break the Mission to Mars.

NASA has formalised plans to send a manned mission to Mars, a journey that could involve 250 million miles of travel on a small spacecraft.

To understand the psychological demands of this Mars journey, Northwestern University has charted a multi-phase study conducted in two analog environments — HERA in the Johnson Space Center in Houston and the SIRIUS Mission in the NEK analog located in the Institute for Bio-Medical Problems (IBMP) in Russia.

The varsity will study the behaviour of analog astronaut crews on mock missions, complete with isolation, sleep deprivation, specially designed tasks and mission control, which mimics real space travel with delayed communication.

“Astronauts are super humans. They are people who are incredibly physically fit and extremely smart,” said Leslie DeChurch, Professor at Northwestern.

“We’re taking an already state-of-the-art crew selection system and making it even better by finding the values, traits and other characteristics that will allow NASA to compose crews that will get along,” DeChurch added.

HERA’s capsule simulator houses astronauts for up to 45 days — a mock mission control outside the capsule — that augments the realism with sound effects, vibrations and communication delays.

The next phase of the research, which began on February 15, involves using the model to predict breakdowns and problems a new HERA crew will experience and making changes to “who works with whom, on what, and when”.

The experiment on the SIRIUS analog in Moscow, will begin on March 15, where four Russians and two Americans, will undertake a 120-day fictional mission around the moon, including a moon landing operation. (IANS)
