The launch of a satellite to provide warnings of solar storms is scheduled for Tuesday, Feb.10, at 6:05 p.m. EST, and assuming it's not delayed again, will be seen on Nasa TV (http://www.nasa.gov/nasatv). For the second time, SpaceX will attempt to have the first stage of the rocket land on a 'drone' ship/barge, although there will be no live video for that.

Earlier the same afternoon, 2:10 p.m., they will be showing a SpaceX cargo vehicle being released from the International Space Station, and then a few hours later it will be splashing down in the Pacific Ocean, although that will apparently not be covered live.
On Wednesday morning Feb. 11 on arianespace.tv (and ESA TV) a webcast is scheduled to begin at 7:45 a.m. EST with launch window opening at 8 a.m. for the European Space Agency's IXV space plane.
