Where Mars InSight cannot succeed in other space probes?

A spacecraft that costs almost a billion dollars is a high-speed approach to a dangerous landing on Mars on Monday, and a nickname of NASA, if the fiery heat continues to enter the atmosphere of the Red Planet. and a half "gave his nickname. minutes of terror.

Prop There is very little room for things to go wrong, uls said Rob Grover, NASA's head of the Jet Propulsion Laboratory at Pasadena, California.

If successful, Mars InSight's entry, landing and landing – was designed as the first task of listening to the inner part of another planet and revealing how many rocky planets have emerged – when NASA's record is about to send a new will add success to Mars' a.

The only nation that has ever made it there in the United States has been, and only NASA's unmanned curiosity robotic rover is still functioning on the surface.

But if it fails, it won't be the first.

Mars didn't have 43 other international attempts to send a 25 orbit, probe, land, or rocket. They either hit the surface, missed the planned trajectories, or disappeared after they were thrown.

Countdown to Mars

There will be no live video streaming on Mars Insight's approach on Monday, and the signals will be forwarded back to the World with an eight-minute delay.

You can't interfere with mission managers if nothing goes wrong. All the descent order is pre-programmed to the built-in flight computer.

Expected to do:

– At 11:30, the Mon Pacific time (0640: 00 Sal Sal AEDT) leaves the cruise phase carrying the spacecraft Mars. After a minute, the spacecraft makes a turn to steer himself for atmospheric input.

– In 1947 GMT, the spacecraft rushes into space at 12,300 miles per hour (19,800 kilometers per hour) as it begins to enter the Mars atmosphere.

– After two minutes, the friction in the atmosphere increased the heat shield temperature to 2,700 Fahrenheit (1,500 Celsius). This intensive heat can cause temporary drops in radio signals.

– In 1951 GMT parachutes were deployed. After fifteen seconds, the heat shield is separated from the spacecraft. Ten seconds later, the ship's three legs are engaged in preparation for deployment.

– In 1952 GMT, a radar is activated to detect the distance to the ground.

– The first radar signal is expected in 1953 GMT, followed by a 20-second separation of the spacecraft with the back shell and parachute. Then, the landing engines known as retrorockets begin to fire. The speed of InSight slows down from 17 miles to a constant spindle (27 km / h – 8 km / h) for smooth descent.

– Touchdown is expected in 1954 GMT.

– The first "beep" from the spaceship's X-band radio was planned for 2001 GMT, indicating that InSight did not survive the descent.

– The first image from the surface of Mars is expected in GMT. However, this image may not be available until Tuesday.

– The orbital model of the Mars Odyssey spacecraft is boarding an overhead plane, if InSight's solar arrays are deployed, NASA will not know until Tuesday at 0135 GMT. This step is very important because the earthquake sensor is powered by Sun for a yearly task.
