Hubble Helps Solve The Mystery of Mars’ Escaping Water

Mars was once a very wet planet. Scientists know that over the last 3 billion years, some of the water went underground, but what happened to the rest?
Now, NASA’s Hubble Space Telescope and the Mars Atmosphere and Volatile Evolution (MAVEN) mission are helping unlock that mystery. To understand how much water there was and what happened to it, scientists need to understand how the atoms escape into space.
A team combined data from Hubble and MAVEN to measure the current rate of these atoms escaping into space. This information allowed them to extrapolate the escape rate backwards through time to understand the history of water on the Red Planet.

Nice video

[@bazpearce9993]

Still plenty left trapped underground.

[@TravisLee33]

Exactly @bazpearce9993

My sincere thanks for sharing it.

So water breaks into H and O, and H leaves with heat because of its super light weight. What happens to oxygen?

[@MichaelWinter-ss6lx]

It makes rust.

@@MichaelWinter-ss6lx thanks!

Good work 💯👏🎉

[@robbabcock_]

Very cool video!

Mars needs a magnetic field.

[@GatoAstronauta]

Beaitiful

[@MrGrimv1G]

Plasma recombination .. guaranteed thats new water formed as plasmas cool allowing atoms to reconnect as molecules.

SAVE HUBBLE!!!!.

Mars is singular. While some cases of possessive for singular nouns ending in s use just an apostorohy, Mars isn't one of them.

It's an Electric Universe. Get over it.

Venus?

[@MCR0709]

Once gravity has disappeared, its water has evaporated into space. That's my understanding.

[@tonywells6990]

Gravity does not disappear.

[@srbrocoli]

atmosphere not gravity
