Mars Rovers: ສອງທົດສະວັດຂອງການລົງຈອດຂອງພຣະວິນຍານແລະໂອກາດເທິງຫນ້າດິນຂອງດາວເຄາະສີແດງ

Two decades ago, two ມີນາ rovers Spirit and Opportunity landed on ມີນາ on 3rd and 24th January 2004, respectively to look for evidence that water once flowed on the surface of the Red ດາວ. Designed to last just 3 months, both the rovers travelled and operated on the ມີນາ surface for much longer than the expected duration for years (Spirit operated for over six years while Opportunity remained active for over 14 years). ມີນາ Exploration Programme of ອົງການ NASA has four ‘Science Goals’- to determine if ມີນາ Ever Supported Life, to understand climate and geology of ມີນາ and to prepare for human planetary missions to ມີນາ. 

ຍານສຳຫຼວດຄູ່ແຝດ ວິນຍານ ແລະ ໂອກາດ, ມີນາ found evidence that long ago ມີນາ was wetter and conditions at ມີນາ could have supported microbial life and contributed to understanding geology and climate of ມີນາ. They changed our knowledge of ມີນາ. Their experiences and their yeoman’s contributions to ມີນາ science paved way for future rovers Curiosity and Perseverance. 

ຫົກ ມີນາ rovers have successfully landed and travelled/operated on Martian ຫນ້າດິນຈົນເຖິງວັນທີ. ຄວາມຢາກຮູ້ຢາກເຫັນ ແລະ ຄວາມອົດທົນ which landed on Martian surface in 2012 and 2021 respectively are currently active and operational and making contributions to ມີນາ ວິທະຍາສາດ.
