5.2.5.2. Planetary Systems Motorized Lightband (MLB)
The Planetary Systems MLB, Figure 5.2.5.2-1, provides a fully qualified and flight proven low shock and
lightweight option for use on Minotaur missions. Multiple sizes of MLBs have previously flown on Minotaur
vehicles. The MLB uses a system of mechanically-actuated hinged leaves, springs, and a dual redundant
release motor to separate the upper ring (mounted to the spacecraft) from the lower ring. The MLB is
flexible and configurable to support various separation force requirements and number of required
separation connectors. The MLB upper ring interfaces to the spacecraft through holes in the upper ring
and remains attached after separation adding approximately 2.04 kg (4.5 lb) of mass. Due to the unique
design of the system and space constraints for tooling, Orbital provided socket head cap screw mating
hardware must be inserted from the launch vehicle side. The MLB offers the unique ability to perform
separation verification tests both at a component and system level.
