There are signs of liquid water on Mars.
The people who'll be there at the press conference provided a clue. They are:
- Jim Green, director of planetary science at NASA Headquarters
- Michael Meyer, lead scientist for the Mars Exploration Program at NASA Headquarters
- Lujendra Ojha of the Georgia Institute of Technology in Atlanta
- Mary Beth Wilhelm of NASA’s Ames Research Center in Moffett Field, California and the Georgia Institute of Technology
- Alfred McEwen, principal investigator for the High Resolution Imaging Science Experiment (HiRISE) at the University of Arizona in Tucson
Pick the odd one(s) out. Lujendra Oiha co-authored a paper in Science a couple of years ago about water on Mars. (Mary Beth Wilhelm is interested in organic biomarkers.)
Neel V. Patel at Inverse guessed it correctly.
Read about it at the Guardian. Here's a preview:
Liquid water runs down canyons and crater walls over the summer months on Mars, according to researchers who say the discovery raises the odds of the planet being home to some form of life.
The trickles leave long, dark stains on the Martian terrain that can reach hundreds of metres downhill in the warmer months, before they dry up in the autumn as surface temperatures drop.You can (maybe) watch the NASA press conference, though I'm having trouble. Probably too many people tuned in (more than 72,800 people are trying to watch it!).
