Space Weather

Another long-lived NASA mission has come to an end, this one after more than seven years of dancing through the perilous belts of radiation around Earth.

NASA's long-awaited space weather mission is making scientists wait again — ironically, due to terrestrial weather.

NASA hopes that the long-delayed launch of a space weather mission called ICON will finally occur tonight (Oct. 9) — but terrestrial weather concerns may scrub the flight.

An Earth-observing satellite called DSCOVR has been stuck in safe mode for three months, and its operators finally have a plan to reboot it — but not for another few months.

NASA is considering two proposals that would study space weather from the sun, which poses a radiation threat to astronauts cruising across the solar system.
