ESA IDA - Gateway Lunar Space Station
Launch:
TBD
Payload:
MiniPIX SPACE
Orbit:
Lunar Orbit
Objective:
Aboard Gateway, specifically in the HALO module, an internal radiation dosimetry system called IDA (Internal Dosimetry Array) is to be installed, developed under a project funded by the European Space Agency (ESA). One of the key instruments in this detector array is currently being finalized by Czech company ADVACAM, which has long supplied miniaturized chips for detailed radiation analysis to customers, including ESA and NASA. Its main scientific objective is to monitor radiation doses to which astronauts are exposed. It will also generate scientific data for radiation mapping, shielding assessments, and more. The MiniPIX SPACE detector will provide real-time information on particle type, energy, direction, time of impact, and point of impact.

ESA - Space Rider
Launch:
2028

NASA - Biosentinel
Launch:
2022
Payload:
Biosentinel
Orbit:
LEO
Objective:
NASA’s BioSentinel, a six-unit (6U) CubeSat, launched to deep space on Nov. 16, 2022. The spacecraft remains healthy and continues to study space radiation on its deep space jouney, traveling approximately 16 million miles further away from Earth every year. The BioSentinel mission was selected as one of the secondary payloads – and the sole biological experiment – to have the rare opportunity to catch a ride to deep space on Artemis I, the first integrated flight test of NASA’s Space Launch System. The primary objective of BioSentinel is to develop a biosensor instrument to detect and measure the impact of space radiation on living organisms over long durations beyond low Earth orbit. While progress identifying and characterizing biological radiation effects using Earth-based facilities has been significant, no terrestrial source can fully simulate the unique radiation environment encountered in deep space.

NASA - Artemis I
Launch:
2022
Payload:
HERA (Hybrid Electronic Radiation Assessor)
Orbit:
Lunar Orbit
Objective:
Artemis I, an uncrewed Moon-orbiting mission, was successfully launched on November 16, 2022. The mission’s primary objective was to conduct a Moon flyby, thereby testing the Orion spacecraft, which included NASA’s Hybrid Electronic Radiation Assessor (HERA). The HERA system, a cutting-edge radiation detector designed by NASA and equipped with ADVACAM’s hybrid pixel detector technology, was fully integrated into the spacecraft. HERA provided onboard analysis and displayed radiation dose rates, linking to an alarm and warning system that activated when a certain dose rate threshold was reached. The Orion spacecraft spent roughly three weeks in space, with six days dedicated to a distant retrograde orbit around the Moon. It came within approximately 130 km of the lunar surface and achieved a maximum distance from Earth of 432,210 km. Our chip-equipped HERA monitor will also be included in future NASA Moon missions Artemis II and beyond.
