Hurry up the six-month touchdown of NASA's InSight Mars mission



In March, everything has come to the end of the six month six month period.

NASA's InSight Nuclear Martian atmosphere will enter supersonic speed, and then the brakes will reach the alien plains dry and dry.

After taking the steps of each route, the flight driver will be above the end of the weekend, almost 160 million kilometers away. The delay in communication between Mars and Earth is eight minutes.

"While we hear nothing about time, the whole thing has already been done," said Tom Hofmann Project at the Jet Propulsion Laboratory at NASA.

"It has happened or it has not happened." The last minute minute adjustments require 1 hour before touching, said Rob Grover, the chief engineer of the aircraft factory.

"We are trying to make everything happen in the first years of the year," he explained.

Insight's do-or-die brief introduction, descent and landing summary:

SIX MINUTES TOUCHDOWN BEFORE

InSight will be an 19,800 kilometer arrow, above the Martian atmosphere over 114 km above the surface. Engineers are 12 degrees attack, almost parallel to the ground.

Too steep, it can burn the spacecraft. Excess surface can be rejected in space. Atmospheric fractions slow down the core, but it creates heat.

Its heat coat is used to protect 2.700 degrees Fahrenheit (1,500 degrees centigrade). Once InSight is 11 kilometers away, the parachute is 1,400 km / h.

THROUGH 3 MINUTES, after wearing a nylon screw, InSight protects its heat and spreads its three legs. After two minutes lowering the two bells, the spacecraft continues to use a radar to determine the velocity and altitude of the supersonic space, about 2 kilometers.

It's less than a minute until touchdown. With a speed of 215 km, the lander dumped the back line and lace. Less than one mile (1 km) above ground.

Fifty-fifty Second, immediately, InSight 12 fall engines continue to slower to the ground and keep them out of the remote rear, and still fall under the paraglider. Landing solar panels will spread to the east and west, and their arms robotic are facing south. InSight's speed is now 27 kilometers, 50 meters high.

TO A THIRD STANDARD, called constant speed, InSight is looking for an 8-kilometer touch point near the equator called Elysium Planitia.

There will be a deeper depth of heat measurements and, in March, year-over-year or two Earth-Volume Volume will increase. NASA chose this place because it could have large and flat rocks that prevented scientific operations. Parking near the equator provides sunlight optimally for solar energy.

"Place is a very safe place," said Grover at a press conference on Wednesday.

TOUCHDOWN! It will take about 2 hours, Mart's time, when landing InSight. 3 p.m. On the East Coast of the US and at noon, JPL Flight Controllers in Pasadena, California.

NASA estimates temperatures in teens or even a single-number Fahrenheit (zero zero). Overnight basses can reach up to 140 degrees Fahrenheit (at least 96 degrees Celsius). March is winter. "Perhaps you do not need an umbrella, but you need a coat and a definite area, if you are on the ground," Grover said jokingly to the reporter in Martian describing the plain bone.

Hello HELLO: While out of the ground, InSight WALL-E and EVE shadowed the CubeSats in the first deep spaces.

The tedious curiosity of the 2008 animated feature films will go through the satellites in a thousand kilometers of Mars, like InSight Land.

NASA's inSight radio signals await one or both relays. If the experiment is achieved, the flight driver may continue the InSight descent and landing, even if it is more than eight minutes. Otherwise, news will start from NASA's Mars Orbiters.

Say the cheese:

InSight's first job, just a few minutes before landing, is to take a picture. They want to see what the ground controllers face. Large rocks or a mountain may be affected by land geological experiments. The red wave needs about 16 points after landing to open the solar panels and start their long winter nap.
