Critical Evaluation of MSL Landing Sites Using HiRISE and MRO Instruments

The selection of landing sites for the Mars Science Laboratory (MSL) was significantly informed by the high-resolution imaging from HiRISE and other Mars Reconnaissance Orbiter (MRO) instruments, which evaluated the scientific and engineering merits of potential sites. Over six years leading up to MSL's launch, nearly 60 candidate sites were imaged multiple times. The final selection included four key sites: a delta in Eberswalde crater, a sedimentary sequence in Gale crater, layered lake deposits in Holden crater, and clay deposits west of Mawrth Vallis.

  1. Selecting Landing Sites for MSL • HiRISE and all of the MRO instruments have played a critical role in evaluating the science and engineering merits of the candidate MSL landing sites. • Nearly 60 sites were imaged over the ~6 years preceding the launch of MSL, many of which were imaged on many separate occasions. • The four final sites (left) include a delta in Eberswalde crater, a 5 km thick sedimentary sequence in Gale crater, layered putative lake deposits in Holden crater, and an ancient sequence of layered clay deposits to the west of Mawrth Vallis.
