[Launch Alert] Launch on Schedule

[Launch Alert]

This morning's (January 19) launch of a Delta IV Heavy rocket from Vandenberg AFB appears to be on schedule. The vehicle is slated to leave south base at 11:05 a.m. PST. There is a 70% probability of acceptable weather.

Although the Delta IV Heavy is a massive rocket, I do not expect the launch to be very visible beyond 50 miles. The most visible part of the launch for observers in outlying areas will probably be a short white contrail created when the Delta passes through altitudes of about 30,000 to 35,000 feet.
