In the not-too-distant future, astronauts destined to be the first people to walk on Mars will leave Earth aboard an Orion spacecraft. Starship will enter Mars’ atmosphere at 7.5 kilometers per second and decelerate aerodynamically. NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. Shorter Mars mission plans have round-trip flight times of 400 to 450 days, but would require significantly higher energy. During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars. According to Space News, the estimated cost of the first Mars mission would be roughly $120.6 billion.That's assuming that the "rough estimate" is anywhere near what it will actually cost to get there — NASA and its contractors don't exactly have a reputation for doing things on or under budget. https://www.huffpost.com/entry/live-on-mars-video_n_7019644 If NASA took people to Mars, it would be similarly expensive. When there is the first transmission of a manned mission to Mars, you can be sure that everything will work perfectly, after decades of training and secret missions, everything will be part of a routine, without scares, like any international trip, without turbulence, it is truth… Fábio Rochel Much like early voyages to the South Pole or the initial moon launches were incredibly dangerous, the first would-be Martian explorers will face huge risks. Mars One mission: a one-way trip to the red planet in 2024 The launch date is still a decade away but preparations are underway for the first human expedition to Mars. Therefore, you will probably leave part of the ship, including all the supplies for the trip home, orbiting Mars, while part of the crew goes to explore the surface. LANDING ON MARS. ; If you vacationed there, you'd see epic sites, like Mars' North Pole, with an ice cap bigger than Texas. The first trip to Mars is planned for 2022, which is an "aspirational" date, according to Musk. Just like you have to wait for Earth and Mars to be in the proper postion before you head to Mars, you also have to make sure that they are in the proper position before you head home. Carried aloft by the tremendous power of a Space Launch System rocket, our explorers will begin their Journey to Mars from NASA's Kennedy Space Center in Florida, carrying the spirit of humanity with them to the Red The vehicle’s heat shield is designed to withstand multiple entries, but given that the vehicle is coming into Mars’ atmosphere so hot, we still expect to see some ablation of the heat shield (similar to wear and tear on a brake pad). A fast Mars mission of 245 days round trip could be possible with on-orbit staging. Mars may be the next great travel destination of the future. The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). With a 500-day trip on the surface and the journey to and from Mars (which would take 180 days each way), NASA is saying the total dosage for the mission would be about 1 Sv.
