Oliver Morton on tomorrow’s 2pm EST ‘significant announcement’ by NASA.
The announcement will no doubt concern water on mars, ice or open water. Open water could leave signs that apparently have greater significance:
“It’s very hard to see how Mars could have been warm enough for open water without the benefit of significant amounts of methane in its atmosphere. Planetary atmosphere experts have told me that the only way they can imagine getting an adequate amount of methane into the atmosphere is by having methane-producing bacteria pump it out.”
