PASADENA, Calif. – They do not call it “7 minutes terror” for nothing.

NASA’s InSight Mars landlord is scheduled to move down on the Red Planet tomorrow afternoon (November 26), and mission group members and agency officials are understandably nervous about the noise.

Less than half of all Mars missions, whether they are orbits or landers, have come to their Red Planet arrivals for decades, said Thomas Zurbuchen, Associate Administrator at NASA’s Scientific Mission in Washington, DC, under a press conference here (November 25) at the agency’s Jet Propulsion Laboratory (JPL).

“So, of course, we are worried,” said Zurbuchen. “We acknowledge that you never take Mars for granted. Mars is difficult.”

The difficulty of landing missions is mainly due to Mars having both a relatively strong gravity pressure and a pointed atmosphere that is only 1 percent as thick as the earth’s Tom Hoffman, InSight Project Manager at JPL. So approaching spacecraft accelerated at high speeds and then having difficulty losing enough energy to slow down before landing, he explained during today’s press conference.

InSight will hit the Martian atmosphere a little before 3 pm EST (2000 GMT) during the trip about 12,300 km / h. The spacecraft must accurately pinch its 12 degree measurement angle, the team members have said: All burners and InSight will burn up; slightly lower, and the vehicle will bounce off the atmosphere and care about space.

Atmospheric pressure will eventually slow inSight down to about 840 mph (1,350 km / h), and then the craft will use its supersonic parachute, Hoffman said. Just before touchdown, InSight will burn up its check valves to stick to the red dirt at just 5km / h. You can keep tabs on all the actions that live on Space.com, with permission from NASA. .

This is the same post, descent and landing (EDL) strategy used by NASA’s Phoenix countries, which was safe in March March 2008. There is no rocket-powered skyscraper, which reduced the Agency’s heavier curiosity on the red plane’s surface in August 2012 . (InSights EDL sequence takes about 6.5 minutes, instead of the 7 minutes of curiosity. However, some NASA officials and InSight team members have rounded off, referring to the forthcoming attempted fire as “7 minutes of terror” Also.)

Both Hoffman and Zurbuchen expressed confidence that InSight will succeed tomorrow, as well as Mission Commander Bruce Banerdt, also by JPL. All three stressed that the mission team has done everything it can to anticipate and alleviate potential problems.

“But you never know what’s going to happen,” said Hoffman. “Everything must be perfect, and Mars can always throw us a curve ball.”

Hoffman also hugged a fall of nerves and he predicted that all stuffed excitement and anxiety will blow up tomorrow when you get the first “I’m OK” signals from InSight on the Mars surface.

“I’m going to completely release my four-year-old,” said Hoffman.

After the printing, InSight – whose name is short for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport” – may come to work. The stationary landlord will be the first spacecraft that will ever explore Mars’s interior, gather data on the structure and composition of the red planet. Such information will shed light on how stony worlds like Mars and Earth form and develop, missionary officials have said.

InSight will do this using a series of super-sensitive seismometers and a heat probe that reaches up to 16 meters (5 meters) below Mars surface. Mission officials will also use the country’s communications equipment to measure the small twist of the Mars axis of rotation, which should reveal important details about the planet’s core.

The $ 850 million InSight Mission was launched on May 5 together with two small cube states called MarCO-A and MarCO-B. Coupon sizes are technology demonstrators designed to show that cube rates really can explore interplanetary space; MarCO duo will also strive to beam home data from InSight during the EDL sequence tomorrow, but this task is not critical to the success of the master. (MarCO-A and MarCO-B will not connect to InSight on the surface, they will fly by Mars.)

InSights launch came about two years later than planned. The probe failed its original launch window in March 2016 after a leak was detected in the vacuum chamber around the seismometer suite. Mars and Earth fit right for interplanetary missions only once every 26 months, so the InSight team had to wait a while even after fixing the leak.
