The Mars Geyser Hopper (MGH) was proposed in 2012 as a NASA design reference mission for a Discovery-class spacecraft concept that would investigate the springtime carbon dioxide Martian geysers found in regions around the south pole of Mars.[1][2]

The power technology that MGH proposed to use was the Advanced Stirling radioisotope generator (ASRG).[3] NASA finished the ASRG design and made one test unit of the device but the program was concluded by the mid-2010s.[4][5] Neither InSight nor any of the next Discovery's semi-finalists use the ASRG or an RTG due to high demand and limited supply of the type of plutonium it relies on.[6]
