Three Tries Before Launch

It took three attempts to launch the JPSS-1 weather satellite. High winds and boats within the launch safety range offshore prevented two earlier attempts.

Ready for Take-Off

With the Mobile Service Tower rolled away, the Delta II rocket is ready to carry the JPSS-1 satellite into orbit for NASA and NOAA.

A Once Over

Ball Aerospace

On Oct. 8, 2015, technicians examined the JPSS-1 satellite during a Launch Configuration Electromagnetic Interference (EMI) test. The EMI test evaluates expected electromagnetic radiation at the launch site.

Passing the Test

On March 29, 2016, JPSS-1 successfully completed a pop and catch deployment test.

By Any Other Name

Here, JPSS-1 is prepared for another round of tests in the acoustic testing chamber in Boulder, Colorado at Ball Aerospace & Technologies Corp.'s Fisher Integration Center. Once it launches, the satellite will be called NOAA-20. After the craft launches from Vandenberg Air Force Base, it will orbit Earth, providing full global coverage twice a day.

And More Tests

At Ball Aerospace & Technologies Corp.'s Fisher Integration Center, JPSS-1 went through more tests inside the EMI/Electromagnetic Compatibility (EMC) chamber.

Together Again

JPSS-1 was restored to its full capacity when engineers reinstalled its Spacecraft Control Processor (SCP2) at the Boulder, Colorado facility.

First Steps in Preparation
