NASA aims to launch astronauts to Mars by the late 2030s or early 2040s. Making that vision a reality will be challenging. Assuming the funding and technology come into play at the right time, for example, the round-trip travel time would still be about 500 days given the distance between Earth and Mars.
The mission plan is in the early stages and could change considerably. But so far, NASA envisions using for a habitat-like spacecraft to ferry crewmembers to the Red Planet, using a hybrid rocket stage (powered by both chemical and electrical propulsion). Four people would make the long journey, with two alighting on the surface, somewhat similar to the model seen in the Apollo program with three astronauts.
Roughly 25 tons of supplies and hardware would be ready and waiting for the crew, delivered by a previous robotic mission. These supplies would include a crew ascent vehicle, already fueled and ready to go for the astronauts to make it off Mars and back into orbit around the planet.
I can't find anything about the June workshop mentioned in the article, I guess already behind schedule :p
