NASA announced Friday plans to send the Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon in Dec. 2022 to study the concentration of water ice.

Why it matters: VIPER will gather data to inform NASA's first global water resource maps of the Moon. The mission's project manager, Daniel Andrews, said VIPER will help answer the question of "if the Moon could really contain the amount of resources we need to live off-world."

Our thought bubble, via Axios' Miriam Kramer: NASA still doesn't know how much water is on the Moon or what form it takes. This mission represents a first step toward helping the space agency characterize that water and figure out exactly what they might need to do to extract it in the future.

President Trump wrote in a tweet Saturday morning that Republicans have an "obligation" to fill Justice Ruth Bader Ginsburg's seat on the Supreme Court following her death Friday.

What he's saying: "We were put in this position of power and importance to make decisions for the people who so proudly elected us, the most important of which has long been considered to be the selection of United States Supreme Court Justices," the president said, tagging the Republican Party. "We have this obligation, without delay!"

At the Supreme Court steps Friday night hundreds of people gathered to pay tribute to Justice Ruth Bader Ginsburg — singing in a candlelight vigil, with some in tears.

Details: If there is a singular mood at the Supreme Court tonight, it’s some kind of a daze manifested by silence.
