**Throwback Episode** This was a lecture given on the cusps of a Space Shuttle Mission involving Colonel Ilan Remon which tragically disjoined on re-entry into the atmosphere. The lecture was given on New Year Day, 2003. We delineate the details of what is entailed in keeping Shabbos on the Space Shuttle while it’s orbiting Earth according to Rabbi J. David Bleich who postulates the scenario according to Rabbi Moshe Feinstein. Unfortunately, only about half the class was recorded.
