Who got to Mars first?First success and more attempts,1964 - 1971NASA's Mariner 4 was the first craft to finally reach Mars. The spacecraft launched on Nov. 28, 1964, and was the first to fly by the planet on July 14, 1965.Mar 1, 2022Taken together, the evidence suggests that Mars was the locale of a planetary nuclear massacre. The theory is that the nukes would vaporise a fair chunk of Mars' ice caps, liberating enough water vapour and carbon dioxide (both of which are greenhouse gasses to warm up the planet substantially.https://www.crown.co.za › item › 2...Why Elon Musk wants to nuke Mars - Crown Publications"This is a concept,” Doctor Śliwa said about the theory. “Unfortunately, it must also be said that it is not very realistic, for quite a prosaic reason (...) because, as estimated by scientists dealing with Mars, the dioxide in Mars's polar caps is simply not enough. Even if 100 percent of it was released, the Martian atmosphere would be many times less thick than the Earth's and temperatures wouldn’t rise sufficiently."https://www.thefirstnews.com/article/musks-nuke-mars-plan-not-realistic-says-leading-scientist-7533A research team has devised a plan to make a portion of Mars more Earth-like by slamming an asteroid into it.This Mars Terraformer Transfer (MATT) concept would create a persistent lake on the Red Planet's surface in 2036, potentially accelerating Mars exploration, settlement and commercial development, the team said."Terraformation need not engineer an entire planetary surface. A city-region is adequate for inhabitation. MATT hits this mark," the Lake Matthew Team, the group behind the idea, wrote in a press release last month.https://www.space.com/36563-terraform-mars-asteroid-strike-lake-matthew.html
