The Lunar Polar Exploration mission (LUPEX) is a robotic lunar mission concept by Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA)[7][8][9] that would send a lunar rover and lander to explore the south pole region of the Moon in 2024.[1][2][6] JAXA is likely to provide the under-development H3 launch vehicle and the rover, while ISRO would be responsible for the lander.[8][10]

The mission concept has not yet been formally proposed for funding and planning.[11]

History[edit]

ISRO signed an Implementation Arrangement (IA) in December 2017 for pre-phase A, phase A study and completed the feasibility report in March 2018 with Japan Aerospace Exploration Agency (JAXA)[12] to explore the polar regions of Moon for water[13] with a joint Lunar Polar Exploration Mission (LUPEX) that would be launched by 2024.[1][14]

ISRO and JAXA held the Joint Mission Definition Review (JMDR) in December 2018. By the end of 2019, JAXA concluded its internal Project Readiness Review.[15]

Since Chandrayaan-2 could not soft land on Moon in September 2019, India started to study a new lunar mission namely Chandrayaan-3 as a repeat attempt to demonstrate the landing capabilities needed for the LUPEX.[16]

On 24 September 2019, in a joint statement by JAXA and NASA discussed possibility of NASA's participation as well.[17]

JAXA finished its domestic System Requirement Review (SRR) in early 2021.[18]

Overview[edit]

The Lunar Polar Exploration mission would demonstrate new surface exploration technologies related to vehicular transport and lunar night survival for sustainable lunar exploration in polar regions.[19][10] For precision landing it would utilize a feature matching algorithm and navigational equipment derived from JAXA's Smart Lander for Investigating Moon (SLIM) mission.[4][20] The lander's payload capacity would be 350 kg (770 lb) at minimum.[5][3][21] The rover would carry multiple instruments by JAXA and ISRO including a drill to collect sub-surface samples from 1.5 m (4 ft 11 in) depth.[22][3] Water prospecting and analysis are likely to be mission objectives.[8][23] Payload proposals from other space agencies might be sought.[7][20]

Payloads[edit]

Few selected Japanese instruments along with the candidate instruments of ISRO and the invited international collaborators by JAXA.[18][24]
