NASA studies plan to send an orbiter to Pluto

Remember when New Horizons swept past Pluto in 2015? That was exciting! Who knew Pluto had a heart? Now scientists are proposing a new Pluto orbiter mission. It would gather details on Pluto’s heart and the rest of its youthful surface, its hazy bluish nitrogen atmosphere, and its system of 5 known moons.

NASA Plans To Send Water-Hunting Robot To Moon Surface in 2022

NASA will send a golf cart-sized robot to the moon in 2022 to search for deposits of water below the surface, an effort to evaluate the vital resource ahead of a planned human return to the moon in 2024 to possibly use it for astronauts to drink and to make rocket fuel, the U.S. space agency said on Friday. From a…

Mid-sized storms spotted on Saturn

An international team of researchers has found that mid-sized storms form near Saturn’s northern pole. In their paper published in the journal Nature Astronomy, the group describes discovering four of the mid-sized storms near the planet’s northern polar region last year and their study of them.

Did the Viking landers find life on Mars in 1976?

For a brief time in 1976, it seemed as if NASA’s Viking landers had found microbes on Mars! Those results have been soundly disputed in the years since, but the original experiment’s principal investigator, Gilbert Levin, still maintains they really did detect Martian microbes.

Juno prepares to jump Jupiter’s shadow

NASA’s Juno mission to Jupiter has now successfully executed a 10.5-hour propulsive maneuver. It’ll keep Juno – a solar-powered spacecraft – out of a mission-ending shadow due to have been cast by Jupiter onto the craft in November.
