Here's what is on tap for Tuesday:

FOX & Friends First (6 a.m. ET)

It's been 20 years since we first left the Earth's atmosphere and more than 200 people have made the trip. Linda Shiner, executive editor of Air and Space magazine, reveals their stories in a new book Space Shuttle, the First 20 Years.

Will Colin Powell's case against Saddam be strong enough to sway the U.N. and signal the start of a war with Iraq? Gary Schmitt, former head of President Reagan's Foreign Intelligence Board and current executive director of the Project for the New American Century, weighs in.

FOX & Friends (7 a.m. ET)

Will Powell deliver a "smoking gun" to the United Nations Security Council? We'll review the evidence with former U.N. weapons inspector Terence Taylor.

As NASA works to uncover the root cause of why Columbia disintegrated, critics are questioning the future of NASA. Do the benefits of space exploration outweigh the risks? We'll be joined by Dr. Robert Park, physics professor at the University of Maryland.

The Columbia tragedy brings memories of the Challenger disaster. What was it like to be in the White House when the 1986 disaster struck? Michael Bohn, author of Nerve Center: Inside the White House Situation Room.

Plus, we'll get reaction to the tragedy from a member of the NASA family, former astronaut Harrison Schmitt.
