Tune in now to NASA TV for a briefing on the upcoming #ISS #spacewalk -
Weather is 40% "go" for today's @SpaceX launch.  #ISS is ready for the ~2.5 tons of science & supplies on Dragon!
The @SpaceX Falcon 9 rocket is on its launch pad, poised for launch at 3:25p ET today to #ISS
Ground controllers @NASAAmes confirmed LADEE impacted the surface of the moon, as planned. Stay tuned for details!

Astronauts on #ISS gear up for Wednesday's spacewalk & tomorrow's @SpaceX cargo launch:…
What's out new header image? @NASAKepler's newly discovered Earth-size planet in habitable zone of another star!

Hudgins: The @NASAKepler team has developed a plan for 2-wheel control. It's now a proposal in NASA's Sr. Review!
Quintana: This planet was validated using the first four years of @NASAKepler's data.
Barclay: M-dwarfs have hardly changed over time. That's why its so difficult to tell their age!
Meadows: We have no definitive evidence that shows a possible atmosphere on this planet.
Meadows: This Kepler 186-F exoplanet absorbs more energy from its star than Earth does from our sun!
Meadows: What makes this finding interesting is studying the way the planet interacts with its star!
Barclay: Kepler 186F circles its star in an orbit like that of Mercury. Therefore, it's more like an Earth cousin.
Barclay:  M-dwarfs are cooler, smaller & dimmer than our Sun. They are great targets for possible habitable worlds.
Quintana: Kepler-186F is closest to Earth in size. It's the first planet we've found that may be habitable.
An Earth-like planet? @NASAKepler found its 1st Earth-size planet in the habitable zone!
Quintana: There are five planets round this star. The inner four are spinning more quickly than Kepler-186F.
Quintana: Evidence shows that other habitable worlds like ours possibly exist.
Our next mission, TESS that launches in 2017, will survey the whole sky for transiting exoplanets!
This new result is based on analysis of data gathered during @NASAKepler’s first four-plus years of operation.
