Sunday Show Guests

Tomorrow is the space shuttle Discovery's turn to shine on the Sunday talk shows: Commander Eileen Collins, Pilot James Kelly and Mission Specialist Charles Camarda will appear on Meet the Press (NBC), Fox News Sunday, and This Week (ABC). They'll be joined by NASA Administrator Mike Griffin on Meet, and former astronauts Buzz Aldrin and Senator John Glenn on TW. Other guests:

Meet the Press: Following the shuttle interviews, Russert will roundtable with David Broder and Eugene Robinson of the Washington Post, John Harwood of the Wall Street Journal, and National Review's Kate O'Beirne.

This Week: Senator Rick Santorum will take to the circuit for the first time in recent memory, discussing his recent book It Takes a Family. Lee Iaococca, the former Chrysler CEO, will also appear. The Santorum interview might be the best chance for any real off-the-wall statements tomorrow: watch for a question about Frist's stem cell stance.

Fox News Sunday: Senate Republican Whip Mitch McConnell and Democrat Chris Dodd will be on, discussing the Roberts nomination, stem cells, Bolton, and the August recess, among other things. The panel this week: host Chris Wallace, Fox' Brit Hume, WaPo's Ceci Connolly, and Juan Williams. [Update: Senator Bill Nelson, also a former astronaut, will also appear. -- 11:33 p.m.]

Face the Nation (CBS): Schieffer lost out on the shuttle crew this week, but he's got probably the Republican duo mostly likely to spit fire at each other: Pennsylvania's Arlen Specter and Kansas' Sam Brownback. The last time these two were on the same show, Specter made the comment during a stem cells dialogue that he was less concerned right now with when life begins than when it ends. Stem cells will be the major issue here, although Roberts may intrude. CBS space analyst Bill Harwood will guest, and the NYT's Elisabeth Bumiller joins in the questioning.

Late Edition (CNN): Iraqi national security advisor Mofawwak al-Rubaie headlines. Senators Joe Lieberman and John Kyl (R-AZ) also will be on, as well as Egyptian Prime Minister Ahmed Nazif and LA counter-terror chief John Miller.
