The Antares rocket launch is back on for 5 p.m. ET Sunday afternoon, as engineers and spectators look for the rocket to lift off from a launch pad at NASA's Wallops Flight Facility. A check of all systems at 10 minutes before its launch was positive.
You just don't know (because who's going to tell you?) that when you leave Earth, travel outside its gravitational reach, hundreds and hundreds of everyday things — stuff you've never had to think about — will change. Like ... oh, how about a wet washcloth?

Keep your eye on the sky Sunday evening; the Lyrid meteor shower is expected to peak. It's the first meteor shower of the spring season.
The Lyrid shower is caused by Earth passing through the orbit of a comet known as Thatcher, though the comet itself hasn't been seen since 1861. Dust particles from the comet will be seen as flashes of light as they burn up in our atmosphere.
