    Really ? so that's why they need a space suit ? If there is an atmosphere it's so little that it could never support life even if terraformed.
    again not enough mass

    Each and every planet and moon have an atmosphere. That does not guarantee that it can support life as we know it. Life on Terra is adapted to its atmosphere through millions of years of evolution and the extinction of those that could not adapt to its changing environment or survive the pressure from competing organisms for the requirements to sustain life. The requirements to support life in our atmosphere are an extremely narrow and minuscule set of possible parameters. And as far as we know unique to our planet. So although all planets and moons have an atmosphere there is only one that we know of that can sustain us.

    They say they brought back a camera from the moon three years after it was placed. It had living bacteria in it.
    wonder where they got the oxygen from......Hint....US!
    If space was truly a vacuum then the tardigrades would never have been able to survive.
    You work it out
    They would have exploded
    Space is suppose to be
    2.7 Kelvin, Minus 270.45 Celsius or -454.81 Fahrenheit
    \Get it

    1) Please give the source for that startling information.

    2) Re: Living bacteria
    Do you mean bacteria actively metabolizing or simply capable of being revived from a stasis state?

    (a) In the former instance:
    A lot of bacteria grow perfectly well without oxygen. In fact, some are not able to utilize oxygen at all, and it may be toxic to them. They are called, respectively, facultative anaerobic bacteria and anaerobic bacteria.

    (b) In the latter instance:
    Most bacteria can go into a state of stasis for preservation. They do not metabolize significantly in that state, but when planted on nutrient media, they revive. Lypholization (vacuum drying ), desiccation (e.g., at the South pole), and inoculation into a non-nutrient media are three such methods. The latter method is particularly useful for labs that rarely need to do it.
