    Default Shuttle viewable from North America tommorow morning



    Spaceflight Now | STS-131 Shuttle Report | Shuttle to streak across America during re-entry

    Assuming an on-time descent, Discovery will plunge back into the discernible atmosphere at an altitude of about 76 miles above the central Pacific Ocean south of the Aleutian Islands at 8:17 a.m., crossing the western Canadian coast "just above where the Winter Olympics were," Lunney said.

    "The vehicle will be about (43 miles up) at that point, traveling at a speed of about Mach 23, moving very fast, very high," Lunney said. "We took a quick look at the weather forecast and we think the western side of the United States will be relatively clear. So hopefully folks there will get a view. The eastern side might be a little bit more cloudy, so hopefully you'll get a hole and you can see it through the clouds."

    With the shuttle surrounded by superheated plasma as atmospheric friction reduces its 5-mile-per-second orbital velocity, viewers in the west will see a "streak of white light way up high," Lunney said. "When it's down lower, it's going to be more the glowing cloud plowing through. I think both will be clearly visible if the clouds allow it to be."

    Here are timeline overviews for both Florida landing opportunities Monday (in EDT; best viewed with fixed-width font):
