The U.S. Navy's first Mobile User Objective System satellite, dubbed MUOS 1, is encapsulated into the Swiss-made nose cone of the United Launch Alliance Atlas 5 rocket at the Astrotech spacecraft preparation facility in Titusville.
The bullet-shaped shroud protects the satellite during ascent through Earth's atmosphere and then gets jettisoned from the rocket at T+plus 3 minutes and 22 seconds.
