Tema je odlicna i bilo bi lepo da pratimo sta se tu dogadja. Inace, Amerikanci pozamasno ispituju Mars sa svojim letilicama, vec odavcno, a zadnjih godina bas zestoko.


Dobro, evo uradicu to

Usput, na drugom linku, tj rover Oportunity, tamo gde dolazi do svog toplotnog stita (heath sheeld) i pronalazi onaj sundjerasti meteorit - veoma mi je cudno da taj meteorit nije ostavio nikakav krater, vec tako lezi tamo kao neka zivotinja u pustinji. Isto tako i taj zastitni poklopac (pogledajte par federa koji leze okolo i jos neki sitniji delici - jbt. samo pravimo smece ).
Izgleda da tamo stalno ima vetrova koji pomeraju taj pesak boje rdje, no za meteorit mi je bas cudno, jer mi izgleda kao poprilican komad; a mozda i nije -  ti roveri su dosta sitni. Ne znam, pitam se
 

Tek tako ne treba.... U vecini slucajeva, retko ko ce pogledati kada su samo linkovi

Spirit, mission designation MER-A (Mars Exploration Rover - A), is the first of the two rovers of NASA's ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition.



The rover completed its planned 90-sol mission. Aided by cleaning events that resulted in higher power from its solar panels, Spirit went on to function effectively over twenty times longer than NASA planners expected following mission completion. Spirit also logged about 10 kilometers of driving instead of the planned 1 km, allowing more extensive geological analysis of Martian rocks and planetary surface features. Initial scientific results from the first phase of the mission (the 90-sol prime mission) were published in a special issue of the journal Science.



On May 1, 2009 (5 years, 3 months, 27 Earth days after landing; 21.6 times the planned mission duration), Spirit became stuck in soft soil. This was not the first of the mission's "embedding events" and for the following eight months NASA carefully analyzed the situation, running Earth-based theoretical and practical simulations, and finally programming the rover to make extrication drives in an attempt to free itself. These efforts continued until January 26, 2010 (6 years and 22 days after landing; 24.6 times the planned mission duration), when NASA officials announced that the rover was likely irrecoverably obstructed by its location in soft soil, though it will continue to perform scientific research from its current location.



There has been no communication with Spirit since sol 2210 (March 22, 2010) and there is some concern that the rover was not able to survive the Martian winter. However, the rover team plans to continue to attempt to contact the lander, which may be hibernating while increasing solar levels charge its batteries, until at least summer solstice at Spirit's location in March 2011.

Opportunity, mission designation MER-B (Mars Exploration Rover - B), is the second of the two rovers of NASA's ongoing Mars Exploration Rover Mission. As of 10 December 2010, it had traveled more than 26 kilometers on Mars since landing successfully at Meridiani Planum on January 25, 2004 05:05 Ground UTC (circa 13:15 local time), three weeks after its twin Spirit (MER-A) touched down on the other side of the planet.[4]



Opportunity has continued to function effectively over twenty times longer than its planned 90-sol mission, aided by solar cell cleaning events, and it continues to perform extensive geological analysis of Martian rocks and planetary surface features.

Mission highlights include completion of the 90-sol mission, discovery of the first meteorite on another planet, Heat Shield Rock (Meridiani Planum), and over two years studying Victoria crater. The rover narrowly survived dust-storms in 2007, and is now making its way to Endeavour crater.



On May 19, 2010, Opportunity reached 2246 sols of operation, making it the longest Mars surface mission in history, breaking the record of 2245 sols set by Viking 1.
