NASA’s mission InSight lands on Mars

-

Mars mission InSight which was launched on May 5, 2018, has landed on Mars on Monday, Nov 26, 2018. 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-kilometer) journey from Earth.

The lander touched down Mars’ equator on the western side of a flat, smooth expanse of lava called Elysium Planitia.

InSight’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.

“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.”

More challenges

“We hit the Martian atmosphere at 12,300 mph (19,800 kilometers per hour), and the whole sequence to touching down on the surface took only six-and-a-half minutes,” said InSight project manager Tom Hoffman at JPL. “During that short span of time, InSight had to autonomously perform dozens of operations and do them flawlessly — and by all indications that is exactly what our spacecraft did.”

Confirmation of a successful touchdown is not the end of the challenges of landing on the Red Planet. InSight’s surface-operations phase began a minute after touchdown. One of its first tasks is to deploy its two decagonal solar arrays, which will provide power. That process begins 16 minutes after landing and takes another 16 minutes to complete.

“We are solar powered, so getting the arrays out and operating is a big deal,” said Hoffman. “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.”

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.

“Landing was thrilling, but I’m looking forward to the drilling,” said InSight principal investigator Bruce Banerdt of JPL. “When the first images come down, our engineering and science teams will hit the ground running, beginning to plan where to deploy our science instruments. Within two or three months, the arm will deploy the mission’s main science instruments, the Seismic Experiment for Interior Structure (SEIS) and Heat Flow and Physical Properties Package (HP3) instruments.”

InSight will operate on the surface for one Martian year, plus 40 Martian days, or sols, until Nov. 24, 2020.

Below are few facts:

  • InSight is also known as Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport.
  • It will take six-and-a-half-month to reach Mars. InSight will travel 300m miles and land on Mars on a broad plain Elysium Palitia on Nov 26, 2018.
  • The mission aims to monitor marsquakes, map the planet’s interior and probe the temperature of the core.
  • It will start geological excavations. It will dig deeper into Mars than ever before – about 5 metres – to record the planet’s temperature.
  • InSight is the eighth lander to Mars sent by NASA so far.
  • However, InSight is the first spacecraft to Mars to learn about the planet’s interiors.  It seeks to answer science’s one of the most fundamental questions: How did the terrestrial planets form?
  • NASA had invited people all around the world to register for this Mars mission. The InSight Probe contains a microchip that stores all the names of participants who have registered their name on NASA’s website.
  • The participants have a boarding pass which will contain their name, boarding number and other details like the launch site, launch date, etc. Though one din’t fly for real, their names have become part of InSight.
  • NASA has given boarding pass to 2,429,807 names out of which 1,38,899 are from India (1).
