Vozidlo Mars 2020 sa prvýkrát postavilo na svoje kolesá

Značky: MarsNASA

DSL.sk, 28.10.2019


Robotické vozidlo Mars 2020, ktoré budúci rok NASA pošle na Mars, bolo prvýkrát celou svojou váhou postavené na svoje kolesá.

Prišlo k tomu už na začiatku mesiaca, NASA to oznámila ale až na konci uplynulého týždňa.

Robotické vozidlo Mars 2020 vychádza z návrhu vozidla Curiosity, ktoré je na Marse aktívne od roku 2012. Misia Mars 2020 má odštartovať v júli 2020 a na Mars priletieť 18. februára 2021.

Kolesá sú zatiaľ zrejme najproblematickejším komponentom robotických vozidiel NASA na Marse a pre Mars 2020 sa ich NASA oproti Curiosity pokúsila vylepšiť.

Curiosity má kolesá z hliníka, majú priemer 50 cm, sú široké 40 centimerov a je na nich 19 výstupkov vysokých 7.5 mm. Veľmi skoro sa ale začali výrazne prederavovať a následne sa im dokonca začali odlupovať pevné dezénové výstupky.

Kolesá na Mars 2020 majú priemer 52.5 centimetrov a majú 48 rovných dezénových výstupkov. Na Mars 2020 sú zatiaľ osadené inžinierske vzorky a vymenené za kusy, s ktorými Mars 2020 poletí, budú budúci rok.

Primárnym cieľom misie Mars 2020 bude nájsť stopy a dôkazy prípadného života, konkrétne stopy po minulom mikrobiologickom živote. Za tým účelom bude analyzovať vzorky pôdy a hornín na miestach s vysokou pravdepodobnosťou prítomnosti života v minulosti a zároveň uloží 30 skúmaviek s materiálom pre ich vyzdvihnutie a dopravu na Zem budúcimi misiami na Mars.

Podobne ako u Curiosity bude komplikované pristávanie trvať cca sedem minút, pričom vozidlo musí pri ňom podľa NASA uskutočniť 27 tisíc prepočtov a akcií.

Ved predsa z evolucnej teorie logicky vyplyva, ze keby boli kolesa vhodne na pohyb po Marse, boli by tam uz priekazne davno vyvinute.

Je skoro vo vyske kolies, tak snad ju nestratia :-)

Mne sa zase paci, ako ma kazde koleso osobneho "kolesara". Pekne s objatim spustat na podlozku, hyckanie a opatera a potom ho vystrelia na Mars medzi sutre do neludskych podmienok :-)

tiez som na to pozeral ako sa s tym hraju v sterilnom prostredi.. a pritom na marse pri pristati s tu sondou jebne o mars medzi sutre len taky fukot, ked ju budu rychlejsie spustat na lane..

mozno sa snazia minimalizovat pritomnost mikroorganizmov na kolesach, aby ich nahodou nepreniesli na Mars a kontaminovali tym vzorky a povrch Marsu, si aspon myslim.

Samozrejme, nepritomnost mikroorganizmov je dolezita, to sterilne prostredie a oblecenie je OK. Ale mikroorganizmov nepribudne, ked ciste koleso hodim o cistu zem

Co konkretne im vadi na bezdusovych tepelne odolnych pneumatikach a davno existujucom plastovom materiale ktory sa po poskriabani sam opravuje ?

Co konkretne im vadi na AC motoroch urcenych do nebezpecnych prostredi ktore Slovenska Tesla vyrabala a predavala od 1960 roku ?

Ja teda neviem ako oni, ale ja by som na vrubkovanych nie duralovych ( letecky hlinik ) ale dokonca len hlinikovych ( nie pevnejsia zliatina s hlinikom ) nejazdil ani len po zemi tu na Zemi. To da predsa hlavu ze sa to hned ulame.

Som si isty ze ak by oslovili Matador, urobi im pneumatiky ake len budu chciet a vydrzia nie 10 rokov, nie 50 rokov, ale 100 rokov za cenu so zlavou, zavolaj hned a dostanes pribalenu nafukovaciu pannu z gumy.
