Immediate stretching from the moment the spacecraft hits Mars's atmosphere with someone touching the rusted surfaces of the red planet what scientists call "seven minutes of terror"
Boat landing on Mars is as difficult as it sounds. More than half of all tasks do not make it safe on the surface. As light signals go more than seven minutes to travel 100 million kilometers to Earth, scientists can not control the process. All they can do is program the spacecraft at its best and wait.
Four-minute terror InSight, NASA's latest Mars explorer, begins on Monday just before 3.00 pm. Eastern time. It is the first task to explore seismic waves on another planet; studying the interior of Mars, researchers seek to find tectonic activities and suggestive of the planet's past.
But first they have to get there.
About 14.47 On Monday, Jet Propulsion Laboratories engineers get the signal that InSight has come into the marsh atmosphere. The spacecraft drops to the surface of the planet at 12,300 miles per hour; Within two minutes, the friction has roasted its thermal shields at 2 700 degrees Fahrenheit. Two Minutes After Supersonic Parachuting Space Spaceship Slows.
From there, the most critical landing checklist opens quickly: 15 seconds to separate the thermal shield. Ten seconds for the feet to be used. Activate radar. Jettison's back cover. Shutdown retrorockets. Direction for landing.
Assuming everyone is doing well, at 12:01 pm the researchers hear a small beep – a signal that InSight is active and works on a red planet.
The goal is to find out what Mars has been and how it has changed since it was more than 4 billion years ago. The results could help solve the mystery of how the red planet became dry and deserted into the world we see today.
At the beginning of Mars's history, Mars may have looked much like the Earth. The enrichment of ancient stones shows that it had a global magnetic field, such as a planet that is rotatable by means of a sheath and a metal core. The field would have protected the planet from radiation, allowing it to keep the atmosphere much thicker than the current one. This, in turn, enabled the connection of liquid water to the surface of Mars; images from satellites reveal the contours of past canyons of past lakes, deltas and rivers.
But the last 3 billion years have been slowly threatened by accidents to the Red Planet. Dynamo died; magnetic field bent; water evaporated; and more than half of the atmospheric was sunburned by solar wind. The purpose of the InSight mission was to find out why.
As InSight makes an unstable landing, NASA can get almost real-time information on its position through MarCo satellites – a small double-space spacecraft named CubeSats, which is involved with InSight's flight to Mars. Everyone has solar panels, a color camera, and an antenna to convey a message from the surface of Mars back to Earth.
If satellites succeed, they can provide "a possible model for a new type of Interplanetary messenger," said System Engineer Anne Marinan NASA Bulletin.
Even without a Marco Spacecraft, NASA should know whether the solar panel's solar panels have been set up on Monday night by the recordings of Mars Reconnaissance Orbiter. During the day, the agency will get the first images of the landing place of the spacecraft – a wide, flat, almost non-existent plateau near the equator of Elysium Planita. That's where science begins.
Unlike the opportunity and the curiosity, the rover, who unleash Mars by finding interesting stones, is designed to sit and listen to InSight. With its Dome-shaped seismic sensor, scientists hope to detect minor tremor associated with meteorite attacks, dust mites, and "marsquakes" caused by the cooling of the interior of the planet. As the seismic waves rush through, they are distorted due to changes in their materials that are encountered – perhaps in molten rock or liquid water tanks – revealing what is on the surface of the planet.
InSight is also a drill that can fill 16 feet – deeper than any Mars instrument has gone in the past. From there, it can take the temperature of Mars to find out how much heat is still flowing out of the planet's body. Meanwhile, two antennas closely monitor the location of the fallout, determining how much Mars will dampen when it drives the sun.
InSight's insights only add to Mars's feelings. They could give you tips on things that happened on earth, billions of years ago. Most of the world's early history has disappeared from the unrest in plate technology, said Secretary-General researcher Suzanne Smrekar.
"Mars gives us the opportunity to see the materials, structure, chemical reactions that are close to what we see on Earth, but it has survived," he said. "It allows us to come back in time."
