Agentia spatiala americana NASA a lansat ieri o sonda spatiala proiectata pentru studierea atmosferei superioare a planetei Marte, intr-o incercare de a intelege cum s-a modificat climatul planetei rosii de-a lungul a miliarde de ani.

Sonda orbitala MAVEN – Mars Atmosphere and Volatiles Evolution – a fost lansata in spatiu la bordul unei rachete Atlas V-401 apartinand ULA – United Launch Alliance – de la cosmodromul Cape Canaveral, Florida.

Calatoria catre Marte va dura aproximativ zece luni, iar MAVEN este programata sa intre in orbita planetei anul viitor in luna Septembrie.

NASA a comunicat anul acesta ca cercetatorii asteapta din partea sondei MAVEN sa furnizeze:  “unprecedented data that will help them understand how the loss of atmospheric gas to space may have played a part in changing [Mars’] climate.”

“We want to better understand how the atmosphere is escaping from Mars,” NASA research scientist Paul Mahaffy told ABC News ahead of Monday’s launch. “Then, we can extrapolate back in time and ask, ‘Was Mars’ climate substantially different than it is today?’”

Misiunile curente ale NASA pe planeta Marte includ Mars Reconnaissance Orbiter, doua rovere de explorare – Spirit si Opportunity, precum si roverul Mars Science Laboratory Curiosity, aceste misiuni insa au ca scop studierea suprafetei planetei.
