The Mars rover Curiosity is driving over a dried-up stream bed.
Looking at the gravel under Curiosity, NASA scientists say the water must have flowed about 1 m/s and been somewhere between 10 cm and a metre deep. That’s a lot of water, although it was probably billions of years ago.
Sheila came to La Palma with a six month contract and has stayed 24 years so far. She used to work as a software engineer at the observatory, but now she's a writer and Starlight guide.

I reallymight really be back again for far more browsing and commenting soon enough.
