The Integrated Systems Test between the MMS spacecraft and United Launch Alliance Atlas V is underway today at Space Launch Complex 41’s Vertical Integration Facility at Cape Canaveral. This test verifies that the spacecraft and the launch vehicle are working together in unison and that the Atlas V and MMS are in full communication with one another. Other communications links with ground support and launch equipment interfaces are also being verified.
After the IST is completed later today , the stand-alone MMS spacecraft functional test which was started Monday will be finished. All launch preparations continue on schedule for a liftoff on March 12.
