UPDATE: Want to see a rocket launch? Here's when and where to watch one on the East Coast

UPDATE: Due to weather conditions, NASA has pushed back the launch of the next Antares rocket to early Saturday morning. Read more here.

If you're in the mood to watch a rocket launch, you're in luck — NASA Wallops is set to launch an Antares rocket this week. 

You're going to have to wake up early — the launch is now scheduled for 4:01 a.m. Saturday — but that early time means visibility will be great across the coast.

The best views will be in the immediate area surrounding Wallops Island in Virginia, where the launch will take place, giving Wallops and Chincoteague a chance to see it in the first 10 seconds. 

If you want to roll out of bed and watch it in your pajamas, no worries: It will be visible up and down the coast by a few minutes out.

• 30 seconds after launch: The launch will be visible in Salisbury and on most of the lower eastern shore of Maryland as well as the eastern shore of Virginia.
• 60 seconds after launch: Almost the entire peninsula, including almost all of Delaware, will be able to see the rocket. That also includes the Virginia Beach area. After about a minute and a half, people as far away as Richmond and Washington, D.C. will be able to see it.
• 90 seconds after launch:  Almost of all of Delaware will be able to see it, as well as the northeast coast of North Carolina. It will become visible in Wilmington, Delaware, within the next few seconds after.
• 120 seconds after launch: The ring of visibility will include central New Jersey and much of eastern Virginia as well as the northeast corner of West Virginia. It will come into view for the southeast corner of Pennsylvania, likely including York, around that point.
• 150 seconds after launch: The rocket will be visible in suburbs of Raleigh, almost the entirety of New Jersey and even New York City. Those in Harrisburg and nearby Pennsylvania towns should be able to see it around that point.
• 180 seconds after launch: Much of the east coast will be able to see the rocket. People from Raleigh to Hartford, Connecticut, from the eastern panhandle of West Virginia to southern New York will have a chance to see the rocket (although at that point, it might be pretty small).

Visibility will depend a lot on clear weather conditions as well as how well you can see the sky where you live. If you live in a neighborhood with a lot of trees, for instance, you might want to have a sleepover at a friend's.

There's also a chance the launch won't happen Thursday for many reasons, including weather (although current forecasts from the National Weather Service indicate it will likely be mostly clear at Wallops Island on Wednesday night and early Thursday). If it gets delayed, current plans indicate it will be pushed to early Friday.

If you watch:
