Asteroid 2004 BL86 passed Earth on Jan. 26, 2015 at 16:19 UTC (11:19am EST). This "movie" of the asteroid was generated from radar data collected on that date by NASA's Deep Space Network antenna at Goldstone, California. Twenty individual images were used. Radar observations allow scientists to better measure an asteroid's size, rotation and location. As a bonus, radar observations of 2004 BL86 detected a tiny moon orbiting the asteroid.

NASA Astronaut Terry Virts, aboard the International Space Station, took photos of the 2015 blizzard in the northeast United States during a night pass Wednesday, Jan. 28, as he orbited 260 miles overhead. This time-lapse video shows his track from Washington, D.C., over Baltimore to New York City and Boston. The sequence also shows lightning and a bit of aurora. Virts is a member of the Expedition 42 crew aboard the station, and has been in space since Nov. 23, 2014. http://www.nasa.gov/station/ HD download link: https://archive.org/details/2015Blizzard-Time-LapseVideoFromInternationa...

NASA's Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall. The GPM Core Observatory launched one year ago on Feb. 27, 2014 as a collaboration between NASA and the Japan Aerospace Exploration Agency and acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellitE Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map. The map covers more of the globe than any previous precipitation data set and is updated every half hour, allowing scientists to see how rain and snow storms move around nearly the entire planet. As scientists work to understand all the elements of Earth’s climate and weather systems, and how they could change in the future, GPM provides a major step forward in providing the scientific community comprehensive and consistent measurements of precipitation.

A Feb. 18 briefing at Johnson Space Center previewed a series of U.S. spacewalks to prepare the International Space Station for new docking ports that will allow future crews launched from Florida, on U.S. commercial spacecraft to dock to the station. On the first EVA, scheduled for no earlier than Feb. 21, NASA astronauts Barry Wilmore and Terry Virts will prepare cables and communications gear for the two new International Docking Adapters, built by Boeing and scheduled for delivery on a pair of SpaceX flights this year. The other spacewalks are slated for Feb. 25th, and March 1. Also, Final Automated Transfer Vehicle, Progress supply ship to ISS, Magnetospheric Multiscale mission, Orion chutes in the wind, Pegasus modifications and more!
