August has been a busy month for the Radiation Belt Storm Probes and the scientists and engineers preparing the twin RBSP spacecraft (A and B) for their 2012 launch. On August 3, NASA approved a new launch readiness date of August 15, 2012 – exactly one year from today. With that new target date now officially on the calendar, the RBSP team at the Johns Hopkins Applied Physics Laboratory (APL) has recently achieved several major milestones with the integration and testing of the spacecraft.

"We are nearly there with A, and B is only a few weeks behind," says Jim Stratton, systems engineer for RBSP at the Applied Physics Lab. "We're very close to having one complete spacecraft."

An Instrumental Milestone

The Radiation Belt Storm Probes team at the Johns Hopkins Applied Physics Laboratory closed February with a flurry of instrument activities and a significant development milestone.

On Feb. 25, technicians installed the Relativistic Proton Spectrometer instruments on each spacecraft. The RPS will measure the intensity of high-energy protons trapped in the inner Van Allen belt; these protons are known to pose a number of hazards to astronauts and satellites. Results of the RPS investigation, led by the National Reconnaissance Office, could help engineers design spacecraft better able to withstand the harsh environs of the radiation belts.

Additional instrument work scheduled for next week includes integration of the RBSPICE and EMFISIS instruments.

With the first Radiation Belt Storm Probes mission simulation just about a month away, let’s check in on the progress of the twin RBSP spacecraft.

The complex process of subsystem integration is going well: both spacecraft (A and B) are currently in a cleanroom at the Johns Hopkins Applied Physics Laboratory in Laurel, Md. There, engineers and technicians are carefully installing the critical parts that will let the probes fly, maneuver and communicate – as well as measure the particles, waves, and magnetic and electric fields that surround Earth.
