Antares Rocket Launch Scheduled for Today

The Antares rocket has ben rescheduled to blast into orbit Sunday after a second launch attempt expected Saturday was scrubbed because of upper-level winds.

If the third time's the charm and all goes according to plan, the commercial rocket, being launched as part of a mission to resupply the International Space Station, should be visible to million of people from the Eastern Seaboard as far west as central Pennsylvania.

Orbital Sciences has released expected views of Antares from various vantage points.

In Maryland, DC, and most other places on the east coast, the rocket is expected to rise no more than 10 degrees above the horizon. That's roughly the height of an adult's fist held at arm's length. If you want to attempt to view the launch, seek an area with a clear view of the southeastern horizon.
