Since last Thursday, February 18 is the day of róver Perseverance touched surface of Marsimages of the neighboring planet continue to enter: the first, immediately after landing, then other high-resolution photos, and even the full video of moments of panic the rover’s descent to hit the bottom of Mars.

Although it is true implementation of technology in this robot is impressive and has state-of-the-art appliances throughout the structure, many wonder why the first two images you were sent in low resolution.
It has been the same in this regard National Aeronautics and Space Administration NASA, for its acronym in English), which has revealed how the Persistence capture and send images. On the one hand, he clarified that the first two images sent minutes after his arrival on Mars were taken by one set of cameras Their main auxiliary function is the controllers that help operate the robot.
(Plus: this is what Mars sounds like, recorded by rover Perseverance).
This set of image capture devices is called the Cameras to Avoid Hazards (HazCams), and consists of six cameras that monitor the terrain and detect hazards in the robot’s path, both front and rear. Also used by engineers to see where the robot arm can move, to take measurements, take photos and collect rock and soil samples.
At the time of landing, Nasa explained, the HazCams were protected by a clear cover, which will be detached later. The quality will therefore increase, not only with this one, but also with the other 17 cameras that the robot has. Of this, nine are engineering another seven for scientific work, as well as the seven riding (including the six Hazcams).
(In context: the SuperCam that will study Mars in search of a past life).
According to the NASANext weekend, if the robot and its cameras are deployed while the data is being processed at the Earth control center, more images and videos will arrive in higher quality.
How do you ship them?
This was the first high-resolution color image sent by Hazard Cameras (Hazcams) installed at the bottom of the Perseverance rover after landing on Mars.
After traveling 480 million kilometers, the róver Perseverance it uses three antennas to hear, see and send images to Earth. The person who fulfills the latter function becomes the ultra high frequency (UHF) antennaTo accomplish this, it sends its signal to NASA orbits around Mars and then from there to the control centers on Earth.

“In general, a radio signal lasts between 5 and 20 minutes To travel the distance between Mars and Earth depending on the position of both planets, Ken Williford, one of the mission leaders, assured Paul Rincón, science editor of the ‘BBC’.
The mission is to search for microbial life on Mars and collect carefully selected samples of rock and regolith (fractured rock and dust) for their future return to Earth; Perseverance’s other tasks will be to characterize the geology and climate of Mars and pave the way for human exploration ‘in situ’.
