NASA Prepares For “7 Minutes of Terror” When InSight Spacecraft Will Land on Mars (Watch Live Stream)

Just hours left till the historic landing on Mars and NASA’s seven-month journey will end up with landing you can watch online.

Nexter.org has found out what is the InSight mission, why it is important and what’s reason for NASA’s expecting “seven minutes of terror”.

“Seven minutes of terror” are coming

In just hours, Mars will get a new visitor from Earth – NASA’s InSight spacecraft that is about to complete its seven-month journey to Mars. If all goes well, a NASA probe named InSight will land near the Martian equator shortly before 3 p.m. EST.

It will have cruised 301,223,981 miles (484,773,006 km) at a top speed of 6,200 mph (10,000 kph). That means spacecraft must slow down from 12,300 mph as it enters the top of the Martian atmosphere — to a complete stop on the ground six and a half minutes later.

“The landing is all completely automatic and autonomous,” says Rob Grover, leader of the Entry, Descent and Landing team at the Jet Propulsion Laboratory in Pasadena, Calif. “We have no ability to actually, kind of, fly the lander to the surface,” Grover says.

Difficulties and mission

The reason real-time control isn’t possible is because it takes a radio signal approximately eight minutes to travel from Earth to Mars. Because the entire landing sequence only takes six and a half minutes, the lander would already be on the ground by the time a signal from Earth arrived.

InSight isn’t a rover. Its mission is to stick to one place after it lands — and study the interior of Mars from the planet’s surface.

The Nasa InSight probe is fitted with loads of powerful sensors and equipment to help collect data. There are solar panels the size of ping-pong tables, and a five-foot robotic arm with grasping fingers.

InSight also has a thermometer nicknamed the “Mole”, which will burrow 16 feet down below the Martian surface to take subterranean temperature readings.

The lander is equipped with wind and heat sensors, which help operate the thermal and wind shields – to protect against damage. And there’s also a built-in seismometer that will work to detect Martian quakes.

As with all recent Mars missions, NASA will be streaming the landing sequence from within Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena.
