It is not an error margin to get InSight to Mars

CABO CAÑAVERAL, Florida, USA (AP) – The ship InSight of the NASA The Martian atmosphere enters the supersonic speed and then rests slowly and safely on the plains of the red planet. This success will take place in the last six months of six months.

After having planned the perfect route each time, the flight driver will not be able to change around 160 km (100 million miles) away from Wednesday in the last week on Wednesday. between Mars and Earth A delay of eight minutes is received for each message transmitted.

"When we hear something of time, everything will end," he said. Tom Hoffman Jet Propulsion Laboratory NASA, project manager. "It happened or it did not happen."

The last minute minute adjustments will take an hour and a half until the spacecraft touches the surface, said Rob Grover, an engineer responsible for the downfall.

"We are making efforts in previous years," he explained.

Six minutes before Friday, it will enter 19,800 kilometers per hour (12,300 miles per hour) of InSight, above the surface of the Martian atmosphere over 114 km (77 miles) above the surface.

Atmospheric friction reduces the speed of the ship, but creates a heat. The InSight thermal shield has a capacity of 1,500 centimeters (2,700 Fahrenheit). When 11 km (seven miles) above the Earth, the paraglider will move to 1,400 km / h (860 mph).

After three minutes, InSight will discard the heat shield and open three landing feet. Its speed is now 215 km / h (134 mph), it will remove its parachute and a rear casing is less than one kilometer (less than a mile).

Almost immediately, the 12 drops in its engines will be clearer by reducing the speed and keeping it in the rear carapace, which is still beneath the parachute. You only have 45 seconds. The spacecraft will turn itself on itself, the solar panels extend to the east and west on the surface of the Martian surface and the arm robotic to the south It will be 27 km / h (17 mph) and 50 meters (164 feet) tall.

Fifteen seconds before, InSight wants to touch Mars 8 km / h (5 mph) near the equator called Elysium Planitia. There, throughout the year, Martian will carry out various scientific tasks, equivalent to the Earth. At nightfall, temperatures would reach 96 degrees C (- 140 F), as it is a winter season.
