Extraterrestrial life

Perseverance Rover, whatever befalls it, is real science

Speculations about space aliens isn’t.

The Perseverance Rover, set to launch quite soon seems like a genuine science attempt to determine if there is or ever has been extraterrestrial life (as opposed to speculations about space aliens):

It is to pick out rocks that might show signs of life and store them for transport back to Earth via a future mission:

Most of the rover’s seven sets of scientific instruments work in service of that goal, including zoomable cameras to pick out the best rocks from afar and lasers and spectrometers to identify a rock’s makeup. After the rover lands in February 2021, it’s capable of collecting and storing 20 samples within the first Martian year (about two Earth years). The NASA team plans to collect at least 30 samples over the whole mission, says planetary scientist Katie Stack Morgan of NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

Fortunately, Perseverance is headed to a spot that should be full of collection-worthy rocks. The landing site in Jezero crater, just north of the Martian equator, contains an ancient river delta that looks like it once carried water and silt into a long-lived lake.

It may take a while to find out but maybe we’ll really know something this time.

    It does not matter to me if there is or is not life on Mars. What does matter is we learn more about the planet. Colonization will happen, but most likely not in my lifetime. Nixon’s betrayal of NASA, replacing rockets with shuttles, cost us greatly. Had he continued with the rockets and introduced shuttles, we would be on the moon right now and possibly Mars. Obama’s betrayal was even greater. He killed the shuttle program and forced us to pay a high price to Russia and Putin to get into space using their rockets.

    Nice video. Good to see a genuine openness to all possibilities. For 200 years astronomers instantly dismissed not only life but water, despite the clearly visible water channels.

    Now if we could get scientists to consider the possibility that life might exist on Earth, we’ll be making progress.
