MESSENGER Mission Operations Manager Reflects on Ten Years in Space

Andy Calloway, of the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., reflects on the MESSENGER Mission, which will end operations on April 30 when the spacecraft impacts on the surface of Mercury. Read about Calloway’s role on the MESSENGER mission here.

The MESSENGER core team consists of individuals from across all aspects of the mission, managing how each of the sub teams work together, influence each other, and affect the mission as a whole.

MESSENGER's Science Team is composed of scientists from different institutions and with different areas of expertise to form a comprehensive, diverse team that is well qualified to address the scientific objectives of the MESSENGER mission.

Each of the MESSENGER instruments has a team devoted to its development, calibrations, and operations during the mission, working to ensure that the returned scientific data will provide unprecedented insights into Mercury.

Each subsystem of the MESSENGER spacecraft has a team of highly qualified engineers involved in the design, testing, and operations of the mission, committed to seeing MESSENGER become the first spacecraft to orbit Mercury.

Mission Operations Center

The MESSENGER Mission Operations Team serves as the interface between the Science and Engineering Teams and the MESSENGER spacecraft, expertly handling all contact with the spacecraft during the mission.

MESSENGER participation can be found all across the country, with some international contributions too. An interactive map shows the many involvements that all come together to create the MESSENGER mission.
