NASA's Journey to Mars

Humans may expect to face some major challenges in Mars exploration. Human beings can travel the universe for over two years. Russian astronaut Sergei Constantinovich Krikalev spent more than 830 days in orbit around the earth (Lyndon B. Johnson Space Center, 2005). The Mars expedition will require the crew to endure a six month planetary journey, live on the earth for one year, and return to the earth on a six month journey. Russian astronaut Valery V

NASA's trip to Mars may officially die. In other words, institutions seem to hardly land astronauts on the red planet in the 2030s, NASA human exploration assistant manager William H. Gerstenmaier recently NASA funded Mars mission to Mars I said it was not. . Current timetable Gerstenmaier also solved potential problems. Authorities did not know how to place heavy ones on Mars like manned spaceships. "I can not date humans on Mars, the reason is really different, which is about a 2% increase at the budget level we are talking about. We do not have a ground system available for Mars Hmm." . "For us, entering, falling, landing is a big challenge for us."

NASA has set an ambitious goal of dispatching humans to Mars in the mid-2030s. Recent report "NASA's Mission on the Mars: Next Steps for Developing Space Exploration" outlines what human beings must do to achieve this goal. These steps continue with the study of the International Space Station (ISS), then including moving the human being from low earth orbit to what we call "test field", the space area near the Moon. This will allow us to break down the limits of our abilities in places where astronauts can safely return home within a few days.
