The InSight arrived at the planet of Bradbury | The module …



The InSight robotic module came to Mars and sent the Earth the first images from the reddish sand of Elysium Planitia, as it is called the largest plain on the planet, NASA confirmed. The spacecraft was able to leave after seven years of investigation and after a seven-month voyage. Seven minutes before 17 yesterday (Argentina time) InSight entered the atmosphere of Mars obliquely, at a distance of 12 degrees from the planet. If they were over, they burned. According to NASA experts, they were "seven minutes of terror" because the module could have bounced and lost in space. The probe moved about 20,000 kilometers per hour, three or four times faster than the speed of a bullet shot by an automatic rifle. They reported that the thermal protector was heated to such an extent that it reached 1500 degrees Celsius, the temperature of the Sun's surface.

"I wish they were here!", Was the message tweeted by the official account of the probe, as he revealed the first image he took while approaching the Martian surface. Until the last moment, technical adjustments were being made so that everything could go well.

The ship was able to resist with effort the difficult entry into the atmosphere of the red planet and the risky task of quickly reducing its speed to only eight kilometers per hour. An operator from the mission's control center confirmed the arrival of the probe to Mars and the announcement made everyone presently shout and embraced effusively at the NASA Jet Propulsion Laboratory in Pasadena, California.

The unmanned spacecraft, which costs $ 993 million, two hours before reaching the atmosphere of Mars, "the input, descent and landing gear (EDL) made some final touches to the algorithm that guides the spacecraft to the surface ". Once stabilized on the surface, the ship unfolded its solar panels to establish a communication with the Earth. Anyway, it was necessary to wait longer so that the first image of the InSight arrived and for NASA to confirm that its solar panels and the rest of their equipment were in a position to start the operations.

The scientific mission charge consists of two main instruments, the SEIS (Seismic Experiment for the Inner Structure) and the HP3 (Sensors for the study of heat flow and physical properties). The device also has the instrument RISE (Experiment for the study of the rotation and internal structure) of the planet.

"I feel Marte and I will soon know your heart. After landing well, I'm here. I'm at home, "it was announced through the official Twitter profile of the probe that since it was launched on May 5, was broadcasting messages on each of the central aspects of the trip.

Each milestone was marked with a message in the first person sent from the device: "It is one of the most intense parts of my mission," it was one of the many shipments. The day before the arrival to Mars, it was announced: "Tomorrow is the great day (…) in about 24 hours I will be at home, in #Marte." The message reached its 80,000 supporters, who invited him to follow the latest report of his terrestrial team on what they "hope to learn" on the red planet. NASA gave life to the space module on social networks, as a way to bring the mission and science closer to the general public, who was able to follow the risky amortization live even in New York Times Square. Some messages from the social network appealed to humor, as when the probe commented on Twitter: "It's lucky that robots can not sweat."
