The speed at which the data is transmitted can seem glacial, especially when the file is a stunning high-resolution video like the one captured by Perseverance. Instead, the data had to be relayed through orbiting spacecraft. There is no high-speed internet connection between Earth and Mars. It has taken a while for the videos to make their way to Earth. “We’re not calling them vesicles at this point, because it’s important for us to stay open to different possible interpretations.”
“One of the possibilities for those holes is that they are called vesicles, which would be due to gas escape from a volcanic rock,” said Kenneth Williford, the deputy project scientist.
“I invite you to sit back and have a listen to what it would sound like to be on Mars,” he said. Gruel instead plays sounds of wind, blowing at about 10 miles per hour, that the rover recorded after it landed. The problem appears to have been some communication error, not a problem with a microphone itself, and Mr. Gruel’s system that failed to work at all was a microphone that was to record the sounds as Perseverance fell through the atmosphere. Chen, saw how the system with which they had worked for years actually performed. This was the first time that engineers, like Mr. The same landing system successfully put an earlier rover, Curiosity, on Mars, but there were no cameras to record that event. One was on the top side, looking up at the descent stage, and the other was on the bottom, looking down at the Martian landscape as the rover approached the ground, setting down within a 30-mile-wide crater named Jezero.Įxcept for a few small glitches, the landing system appeared to perform flawlessly. In addition, there was one camera on the descent stage - the rocket-powered jetpack that lowered the Perseverance rover to the ground - and two on the rover itself. Skycrane maneuver has started … … about 20 meters off the surface.” “We’re getting signals from - tango delta.” “Touchdown confirmed - Perseverance safely on the surface of Mars, ready to begin seeking the signs of past life.” We have started our constant velocity accordion, which means we are conducting the Skycrane - about to conduct the Skycrane maneuver. Velocity is about 75 meters per second at an altitude of about a kilometer off the surface of Mars.” “We have completed our terrain relative navigation, current speed is about 30 meters per second, altitude of about 300 meters off the surface of Mars. We are currently performing the divert maneuver. We have confirmation that the backshall has separated. Current velocity is 83 meters per second at about 2.6 kilometers from the surface of Mars. We have confirmation that the landing vision system has produced a valid solution, and part of terrain relative navigation. Our current velocity is about 90 meters per second at an altitude of 4.2 kilometers. We’re coming up on the initialization of terrain relative navigation, and subsequently, the timing of the landing engines. Perseverance is continuing to descend on the parachute. Current velocity is about 100 meters per second, 6.6 kilometers above the surface. Current velocity is 145 meters per second at an altitude of about 10 - 9 and a half kilometers above the surface.” “Nav filter converged - solution, 3.3 meters per second, altitude 7.4 kilometers.” “Now has radar lock on the ground. This allows both the radar and the cameras to get their first look at the surface. Our current velocity is 150 meters per second at an altitude of about 12 kilometers from the surface of Mars.” “Heat shield prepped.” “Perseverance has slowed to subsonic speeds and the heat shield has been separated. “We are starting to straighten up and fly right maneuver, where the spacecraft will jettison the entry bounce masses in preparation for a parachute deploy and to roll over to give the radar a better look at the ground.” “- Indicates chute deployed.” “The navigation has confirmed that the parachute has deployed, and we are seeing significant deceleration in the velocity.
