NASA is planning to put astronauts in orbit of the red planet by 2033, and land them successfully on the surface of the Red Planet on 2039.

Addressing a conference, representatives from the Planetary Society, the largest non-governmental space advocacy organization worldwide, provided in detail the information about the results of the workshop where they discussed the feasibility and cost of the Mars mission saying they were happy to say that the mission is both plausible and within the budget of NASA.

Scott Hubbard, professor at Stanford University Department of Aeronautics and Astronautics and a member of the Planetary Society's board of directors, says that, "We believe we now have an example of a long-term, cost-constrained, executable humans-to-Mars program."

Two other science experts, Bill Nye (Planetary Society CEO) and John Logsdon (professor emeritus at the George Washington University Space Policy Institute and board of directors' member in Planetary Society) also addressed the conference along with Hubbard.

NASA's Jet Propulsion Laboratory has created the plan along with suggestions of the Planetary Society, was discussed in detail including the feasibility, affordability and the benefits of a mission to the red planet.

The 2033 orbital mission is seen as a very important step for the whole mission as astronauts will spend nine months traveling to the planet and another 12 months circling the two moons - Phobos and Deimos. The scientists are planning to study these two moons and potentially use it as a hideout to maneuver rovers on Mars.

The scientists at world's premier space agency are also planning to use the Orion spacecraft to transfer crew members from Earth into orbit around the moons and then to the surface.
