The first of the two ARTEMIS spacecraft entered lunar orbit this morning. ARTEMIS was the first mission to orbit the moon's Lagrangian points and this is the first ever attempt to move from the Lagrangian into lunar orbit.
It took one and a half years, over 90 orbit maneuvers, many gravitational boosts and little fuel to move two spacecraft from their orbits around Earth to their new home around the moon.
In Sept. 1859 the sun unleashed one of the most powerful storms in centuries. This week, officials have gathered in Washington DC to ask themselves a simple question: What if it happens again?

Cue the surfing music. Scientists have spotted the iconic surfer's wave rolling through the atmosphere of the sun. More than just a nice photo-op, the waves hold clues as to how energy moves through that atmosphere.
At NASA's Goddard Space Flight Center, scientists and engineers are working on a crucial element of the the Magnetospheric Multiscale (MMS) mission to study magnetic reconnection: the Fast Plasma Instrument (FPI).
More than 30 years after they left Earth, NASA's twin Voyager probes are now at the edge of the solar system. The message is, "Expect the unexpected."
