NASA's new Space Launch System (SLS) is about to go into full-scale fabrication after a detailed review. SLS Block 1, which just passed a design review milestone, will go to an asteroid placed in lunar orbit, and eventually to Mars. Read the rest

Aww. Poor little Pluto.
NASA’s New Horizons spacecraft is expected to radio home any minute now. We're watching on NASA TV. The moment will end a nearly 22-hour radio blackout as the probe focused on a series of close-up observations of Pluto and its moons.
From SpaceFlight Now:
Engineers expect to lock on to a carrier signal, then start receiving housekeeping data on the status of the New Horizons spacecraft. No science data will come down during Tuesday night’s pass.
“The reason why you’re not seeing more things immediately is because the spacecraft is spending all its time making the observations of the Pluto system,” says Hal Weaver, New Horizons’ project sciences from the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. “That’s what we wanted to do. Of course, you want to optimize the scientific return from the mission.
A signal from New Horizons will be a celebratory moment for the hundreds of engineers and scientists working on the mission. The cessation of communications was part of the plan going into the flyby because New Horizons carries a fixed antenna, meaning mission managers have to choose between contacting Earth and conducting scientific work at Pluto.
"I propose a Moon village on the far side of the Moon," says Johann-Dietrich Woerner who has been in the role of Director General of the European Space Agency (Esa) for just a week.
On July 14, 2015, New Horizons will take the first close-up pictures of Pluto, exactly 50 years to the day after Mariner 4 flew by Mars and took the first close-up pictures ever of another planet.
