NASA really wants to go to Mars in the 2030s. Last week, the agency released a report about its progress and plans for the #JourneyToMars. Though the report is mostly filled with optimism and abstract goals, it does outline a few of the awesome/important technologies that NASA hopes to develop in the coming decades. Here are a few:

Really Big Rockets

The successor to the Space Shuttle could be ready for liftoff as early as 2018. When it does take off, NASA's Space Launch System will be able to carry 70 metric tons of supplies into orbit. Later, it could send payloads of up to 130 metric tons into a trajectory towards Mars.

At 382 feet tall, the SLS will eventually be the largest launch vehicle ever built, and even more powerful than the Saturn V rockets that carried the Apollo astronauts to the Moon. "This payload capacity far exceeds the capability of current and planned commercial launch vehicles," says the report.
