Here Are the Key Moments in Perseverance’s High-Stakes Mars Landing – NBC Los Angeles


A collection of hold-your-breath moments Thursday will decide the success or failure of NASA’s Perseverance mission when the company makes an attempt to land its fifth rover on Mars. 

The touchdown, scheduled for 12:55 p.m. PT, is the highest threat portion of the practically seven-month journey from Earth to the Red Planet. Before the spacecraft touches down in Mars’ Jezero Crater, the mission crew faces a collection of milestones generally referred to as “seven minutes of terror.”

Here’s what to anticipate throughout that important window. The occasions under truly happen 11 minutes, 22 seconds sooner than famous due to the distance alerts journey from Mars to Earth. 

12:38 p.m. PST: Cruise Stage Separation

This is the a part of the spacecraft that flies Perseverance and the Ingenuity Mars Helicopter.  It will separate from the capsule as the spacecraft begins the ultimate phases of the journey.

12:48 p.m. PST: Atmospheric Entry

Traveling at about 12,100 mph, the spacecraft will enter the prime layer of Mars’ environment. This is the starting of the mission’s seven minutes of terror.

12:49 p.m. PST: Peak Heating

This is the place issues actually begin to warmth up. Due to friction from the Martian environment, the shielded backside of the spacecraft will heat to an astounding 2,370 levels Fahrenheit. 

12:52 p.m. PST: Parachute Away

Time to hit the brakes. A parachute will deploy at supersonic pace. The spacecraft is provided with new Range Trigger expertise, which determines the actual deployment time and improves its capacity to hit the touchdown spot. 

Heat Shield Separation: 20 Seconds Later

The warmth protect that protected the spacecraft throughout that high-speed entry will detach 20 seconds after parachute deployment. That permits the rover to make use of radar to find out how far it has to go to succeed in the floor and discover a secure touchdown website.

Back Shell Separation: 12:54 p.m. PST

Now it’s time for some much more exact maneuvering. Once the spacecraft sheds its again half, together with the parachute, a jetpack system will use retrorockets to information and sluggish the craft. 

Touchdown: 12:55 p.m. PST

It is one in all the sweetest sounding phrases in area journey — landing. This ultimate step includes a sky crane maneuver in which the rover shall be lowered by tethers hooked up to the beforehand talked about indifferent respectable stage. Using a bridle, the descent stage and hooked up rover will proceed decreasing at a rate of about 1.7 mph till landing is detected. 


Once on the floor, the rover will first take photos of its touchdown location.

Anthony Yanez explains why scientists selected the explicit touchdown website and what they hope to seek out, on NBC4 News on Tuesday, Feb. 16, 2021.
