COLUMBIA, Md., April 4, 2011 (GLOBE NEWSWIRE) -- Integral Systems, Inc., (Nasdaq:ISYS) today congratulated NASA and the Johns Hopkins University Applied Physics Laboratory (APL) for successfully inserting the MESSENGER probe into orbit around the planet Mercury.

"Integral Systems congratulates NASA and APL on the success of the MESSENGER mission as the MESSENGER probe became the first spacecraft ever to enter into orbit around the planet Mercury," said Paul Casner, CEO of Integral Systems. "MESSENGER has traveled almost five billion miles, completed 15 orbits of the sun and traveled at an average speed of 84,500 miles per hour on its way to Mercury. The recently published pictures of the surface of Mercury sent from MESSENGER are a testament to the remarkable engineering accomplishment."

Integral Systems has been an instrumental part of the MESSENGER program, providing its EPOCH Integrated Product Suite (IPS) satellite command and control software solution. EPOCH was used during the Integration and Test (I&T) phase to ensure the spacecraft's flight readiness and continues to support on-orbit operations.

Casner continued, "Integral Systems is proud to join NASA and APL in supporting the MESSENGER program. In conjunction with the MESSENGER team, we provided a cost-effective, commercial product-based solution that supports NASA's mission to develop low-cost, scientifically focused missions."
