High-energy Ion Telescope Instrument Ready for Installation on IMAP Spacecraft

Scientists and engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are poised to deliver the High-energy Ion Telescope (HIT) instrument.
Another of the instruments planned for flight aboard NASA’s Interstellar Mapping and Acceleration Probe (IMAP) is ready for installation on the spacecraft.
The Interstellar Mapping and Acceleration Probe (IMAP) has successfully completed Key Decision Point D (KDP-D). This milestone allows the mission to move from development and design to the assembly, testing, and integration phase.
NASA's Interstellar Mapping and Acceleration Probe (IMAP) is embarking on its yearlong integration and testing campaign, during which all of the instruments and components will be added to the spacecraft structure, tested to ensure they will survive the harsh environments of launch and space, and made ready to execute its mission.
The Interstellar Mapping and Acceleration Probe (IMAP) marked the completion of an important step on the path to spacecraft assembly, test, and launch operations this week at Johns Hopkins Applied Physics Laboratory (APL) in Maryland.
NASA's Interstellar Mapping and Acceleration Probe (IMAP) mission held a critical design review (CDR) last week with a NASA Standing Review Board (SRB). This mission-level review was the culmination of individual CDRs conducted for all the instruments and subsystems.
NASA and the UK Space Agency have agreed to cooperate on NASA's heliophysics mission, the Interstellar Mapping and Acceleration Probe (IMAP). The agreement, signed Sept. 22, 2021, will allow Imperial College London (ICL) to design and build one of IMAP's 10 instruments – a magnetometer called MAG – as well as provide ground support and personnel necessary to support the instrument and the IMAP science team.
NASA's Interstellar Mapping and Acceleration Probe – IMAP – has completed a key milestone in mission development. After rigorous review, IMAP has passed what is known as Key Decision Point C, or KDP-C, which marks the mission's progression from formulation to implementation.
To accommodate schedule changes due to precautions regarding COVID-19, the preliminary design review for NASA's Interstellar Mapping and Acceleration Probe, or IMAP, has been moved from February to May 2021. Similarly, the launch readiness date is delayed from Oct. 1, 2024, to Feb. 1, 2025.
NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the agency's Interstellar Mapping and Acceleration Probe (IMAP) mission, which includes four secondary payloads.
