    Exciting times! Although I don't know what it has to do with Genesis.

    Its for the literalists who think life was first formed on earth.

    Considering Genesis is about the formation of the earth, I don't think a literalist reading of it precludes other planets being formed by God differently. But then, literalists do tend to view the universe with humans as the center of everything, and anything that upsets that self-elevating view is generally regarded as evil.

    I suspect there is life on Mars, I believe this because N.A.S.A might have put it there.

    NASA Press Release, May 2014 "In another investigation, spores of Bacillus pumilus SAFR-032 and another spore-forming bacteria, Bacillus subtilis 168, were dried on pieces of spacecraft-quality aluminum and subjected for 1.5 years to the vacuum of space, cosmic and extraterrestrial solar radiation and temperature fluctuations on EuTEF. These samples also were subjected to a simulated Martian atmosphere using EuTEF. Most of the organisms exposed to solar UV radiation in space and in the Mars spectrum were killed, but when UV rays were filtered out and samples were kept in the dark, about 50 percent or more of those subjected to other space- and Mars-like conditions survived. That makes it likely that spores could survive a trip on a spacecraft to Mars if they are sheltered against solar radiation, perhaps in a tiny pocket of the spacecraft surface or underneath a layer of other spores."

    I've been following the space race since the late 1950's, so this is exciting for me.

    I like international cooperation with space exploration. I liked the Apollo Soyuz link up, I also appreciate the international scientific research done on the International Space Station.

    I'd be happy with any fossilized or preserved specimens, and finding life alive and well would set a new president that we are not alone in the universe.

    Its a prospect I think most people are ready to handle if such a finding were announced.

    Genesis did mention in the beginning there was a void. I'm guessing that would preclude other bodies and stars including life on them.

    I suppose the interpretation can skew in several directions in terms of how Genesis is looked at.

    Yes, and all of those people at JPL essentially doing nothing. Their work was done before the landing started. What we saw was all after the "Seven minutes of terror" had occurred.

    Currently Mars is 11.2 light minutes away from the Earth. That means when the Seven Minute started that Perseverance had already landed 4 minutes ago. If something had gone wrong it takes 11.2 minutes for the signal to get to us and if there were any changes of orders it would take another 11.2 minutes for the signal to get back. That was what was so scary about the landing. Nothing could have been done to change it for some time before it even entered the atmosphere of Mars.

    None - agnostic with strong irreligious tendencies.
    Some info here:

    Hero to Jezero: Perseverance, NASA's most advanced geologist rover, lands on Mars, beams back first pics

    The successful landing means the Terrain Relative Navigation system has passed its test. "It will be used for the upcoming lunar landing missions in the Artemis program," said Munk. "I fully expect it will be used on everything from small robotic missions up to human-scale missions to Mars. It's a building block for precision landing technologies. It will lower the risk for crewed missions since it can perform hazard testing."

    An automatic means of landing anywhere would be an obvious boon to any type of landing - and this vehicle (with radar, for example) does seem quite a step forward.

    Just four months after NASA's previous Mars rover Curiosity landed on our neighbor in the Solar System in December 2012, the American agency announced it was going to spend billions of dollars to create another trundle-bot that promised to be bigger and better. The end result was Perseverance: a 1,025kg nuclear energy-powered, SUV-sized six-wheeled robot carrying a tiny foldable helicopter strapped to its belly.

    The nuclear-powered bit might not have been mentioned so much in the news, given the chance of an accident whilst launching, but no doubt does give the vehicle a much better chance of not having to be reliant on solar radiation for such power - and presumably it was just a radioactive isotope anyway. As in:

    A Nuclear Power Plant Arrives on Mars, Rover Attached (nei.org)

    (Powering all this scientific discovery will be a radioisotope thermoelectric generator (RTG), essentially a nuclear battery, carrying 10.6 pounds of plutonium fuel.)

    Built using components designed for Curiosity, the latest rover is pretty similar to its predecessor. It also comes armed with numerous cameras to snap Martian terrain, spectrometers to detect chemical compounds, sensors to monitor weather, and a robotic arm. However, Perseverance also has a few new tricks up its sleeve, including an x-ray laser to zap rock samples, microphones to record Martian sounds, an electrolysis machine to produce oxygen from carbon dioxide, and a drill to cut off chunks of regolith to be bottled in capsules that will be collected later and flown back to Earth in a future mission, depending on funding. All in all, the vehicle has seven main instruments alongside two primary radiation-hardened RAD750 computers.

    Computers, even if a bit dated, built by the British?

    Looks like my Amstrad 6128 had four times the ability of the first moon-lander. :D
