Lt. Barbara Braun of the AFRL was the program manager for the satellite.[2] MightySat-1's mission ended when it re-entered the atmosphere at 17:11 UTC on November 21, 1999.[3] References1. ^1 {{cite web|last=McDowell|first=Jonathan|title=Master Satellite List|url=http://planet4589.org/space/log/satcat.txt|publisher=Jonathan's Space Report|accessdate=26 February 2014}} {{Portal|Spaceflight}}{{AFRL spacecraft}}{{Orbital launches in 1998}}{{DEFAULTSORT:Mightysat-1}}{{US-spacecraft-stub}}2. ^1 2 3 {{cite web|title=MightySat 1|url=http://www.astronautix.com/craft/migysat1.htm|publisher=Astronautix|accessdate=26 February 2014}} 3. ^{{cite web | url=http://www.globalsecurity.org/space/systems/mightysat.htm | title=MightySat-1 | accessdate=2008-07-29 | publisher=GlobalSecurity.org}} 3 : Spacecraft launched by the Space Shuttle|Spacecraft launched in 1998|Spacecraft which reentered in 1999 |
