Will Mars InSight succeed if other space probes are not?


Spacecraft, which costs nearly $ 1 billion, is likely to land on Mars on Mars if it can cope with a quick approach and hot heat to become a red planet's mood, a process where NASA is nicknamed "six and a half minutes of terror."

"There is not much room to go wrong," said Rob Grover, NASA's Jet Propulsion Laboratory's headquarters, landing and landing team manager at Pasadena, California.

If it succeeds, Mars InSight – designed for the first task to listen to the interior of another planet and reveal how rocky planets – will mark NASA's record when it comes to a spacecraft in Mars.

So far, the United States is the only country that has done it, and only NASA's unmanned curiosity robotic drums are still tools on the surface.

But if it fails, it is not really the first.

43 other international companies send orbits, probes, landlords, or roveries to Mars has not done so. Either they came to the surface, left their planned orbit or disappeared after the launch.

Countdown to Mars

Mars Insight's approach will not be broadcast live on Monday, and the signals will be sent back to Earth on eight minutes delay.

Also, mission leaders can not intervene if something goes unsuitable. The entire landing order is pre-programmed for the aircraft on board.

What to expect:

– At 11.40 o'clock in Malta, Pacific time (0640 am AEDT), the spaceship separates the cruise line that carried it to Mars. One minute later, the spacecraft makes the turn orientated to the atmosphere.

– The 1947 GMT spacecraft runs into space at 12,300 miles an hour (19,800 km / h) when it begins to enter the atmosphere of Mars.

– Two minutes later, the friction with the atmosphere raises the thermal protection to a peak of 2700 Fahrenheit (1500 degrees Celsius). This intense heat can cause temporary interruptions in radio signals.

– At 1951 GMT, paratroop for use. Fifteen seconds later the heat shield differs from the spacecraft. For ten seconds, Lander's three feet are installed to get in touch.

– During 1952 GMT, the radar activates the distance penetration into the ground.

– The first radar signal is expected in 1953 GMT, followed by 20 seconds later on the spacecraft's separation from the backcourses and parachutes. Then the exhaust engines, known as retrorockets, begin to shoot. InSight's speed decelerates dramatically from a speed of 17 km / h to a steady 5 mph (27 km / h).

– The speed is expected to be 1954 GMT.

– The first "beep" on the X-band radio on the spaceship – indicating whether InSight survived the landing – is scheduled for 2001 GMT.

– The first picture of the Mars surface is expected in 2004 GMT. However, it is possible that the image may not arrive until Tuesday.

– The Mars-Odyssey spacecraft's orbital design, flying above, means that NASA does not know Tuesday until March 01, if InSight solar panels have used or not. This step is decisive because the sun has given the explosion sensor a one-year task.
