I spy signs of life
Let’s take a look at some of the cameras and technology aboard Mars 2020
Two sets of colour navigation cameras will aid the rover’s autonomous navigation. Cameras on the rover’s mast will see objects as small as a golf ball from 25m away.
Positioned inside the rover’s underbelly, Cachecam watches over the samples collected from the Martian surface.
This will fire laser pulses to areas smaller than 1mm from a distance of more than 7m away and in combination with a camera and spectrometers seek organic compounds that could provide evidence of past life on Mars.
This instrument identifies chemical elements using X-ray fluorescence. The micro-context camera also provides detailed images of the rock and soil textures.
This pair of cameras can produce colour images and video and 3D stereo images with a powerful zoom lens.
Six hazard-detection cameras, four at the front and two at the rear of the rover, will evaluate potential hazards such as large rocks and dunes, enabling the rover to navigate around them.
With the use of spectrometers, a laser and camera lenses, SHERLOC and WATSON can detect organics and minerals in the search for microbial life.
