This is the itinerary of the arrival of Perseverance to Mars | Digital Trends Spanish


At 12:55 pm Pacific Time (15:55 pm ET) on February 18, NASA’s Perseverance rover, the fifth US rover on the red planet, is scheduled to land on Mars.

According to engineers at NASA’s Jet Propulsion Laboratory (JPL), where the mission is managed, the spacecraft is in good shape and on its way to land in Jezero crater.

Perseverance is considered NASA’s most ambitious mission to Mars to date, as it will focus on finding out if there was ever life on Mars.

“To answer this question, the landing team will have to take us to Jezero Crater, the most challenging Martian terrain ever targeted for a landing,” said Thomas Zurbuchen of the Science Mission Directorate at NASA Headquarters.

Jezero is a basin where scientists believe that an ancient river emptied into a lake and deposited fan-shaped sediment. Scientists believe that the sector is likely to retain signs of life from billions of years ago.

Challenging terrain

POT

Only 50 percent of previous landing attempts on Mars have been successful. However, the challenge is greater this time, due to the geological features of Jezero, such as steep cliffs, dunes and boulders.

“No landing on Mars is guaranteed, but we’ve been preparing for a decade to put the wheels of this rover on the surface of Mars and get to work,” said Jennifer Trosper, deputy director of mission projects at JPL.

According to NASA, Perseverance can safely land on Mars without communications with Earth, as it has pre-programmed instructions and significant autonomy. Once on the Martian surface, one of your first activities will be to take photographs and transmit them to Earth.

Perseverance landing itinerary on Mars

NASA will broadcast the entry, descent and landing of Perseverance live starting at 2.15 PM on Thursday, in a process that has been dubbed the “seven minutes of terror.”

Engineers expect to receive notice of the following key milestones:

  • Cruise Stage Separation (3:38 pm ET / 12:38 pm PT): the part of the spacecraft that has been flying with Perseverance, with the Ingenuity Mars Helicopter, is detached from the entry capsule.
  • Atmospheric Entry (3:48 pm ET / 12:48 pm PT): the spacecraft is expected to reach the top of the Martian atmosphere traveling at about 12,100 mph (19,500 kph).
  • Maximum warm-up (3:49 pm ET / 12:49 pm PT): Friction from the atmosphere will heat the underside of the spacecraft to temperatures of about 1,300 degrees Celsius (2,370 degrees Fahrenheit).
  • Parachute Deployment (3:52 pm ET / 12:52 pm PT): the spacecraft will deploy its parachute at supersonic speed around.
  • Heat Shield Separation: the protective bottom of the entry pod will come off about 20 seconds after the parachute deployment. This allows the rover to use radar to determine how far it is from the ground and to use its terrain-related navigation technology to find a safe landing site.
  • Hind Carapace Separation (3:54 pm ET / 12:54 pm PT): The rear half of the entry pod that is attached to the parachute will separate from the rover and jetpack. The latter will use retro rockets to slow down and fly to the landing site.
  • Landing (3:55 pm ET / 12:55 pm PT): The descent stage of the spacecraft, using the maneuver of the overhead crane, will lower the rover to the surface with nylon straps. The rover should land on the surface of Mars at a speed of 2.7 kph (1.7 mph).
