    NASA is investing in a rocket that could get humans to Mars and back in 2 months — and travel at 100,000 mph

    Once fully developed, the Pulsed Plasma Rocket could blast through space at 100,000 miles per hour.
    • NASA aims to send astronauts to Mars by the 2030s. But with current technology, the journey will be years long.
    • That's why NASA invested in a new type of rocket that could shorten the trip to just 2 months.
    • Reducing the amount of time astronauts spend in spaceflight is critical to their health.

    NASA has invested $725,000 in a new rocket system that could solve one of the major obstacles standing in our way of sending humans to Mars : travel time.

    With current technology, a round-trip to the red planet would take almost two years. For astronauts, spending that much time in spaceflight comes with big health risks.

    They'd be exposed to high levels of solar and cosmic radiation , the harmful effects of zero-gravity, and a long period of isolation.

    Space radiation is arguably the biggest threat. Astronauts who spend just six months in space are exposed to roughly the same amount of radiation as 1,000 chest X-rays, and this puts them at risk for cancer, nervous system damage, bone loss, and heart disease, according to NASA.

    The best way to reduce radiation exposure and other harmful health effects is to shorten the length of the trip, Troy Howe, president of Howe Industries, told Business Insider. That's why he's teamed up with NASA to develop the Pulsed Plasma Rocket (PPR): a new rocket system that could shorten a round-trip to Mars to just two months.

    This technology "holds the potential to revolutionize space exploration," NASA wrote in a statement , and could one day take humans even further than Mars.

    It will be another 20 years before the PPR is ready to blast into space. But when it is, Howe Industries hopes it'll significantly expand the range of human space exploration.

    The PPR is a propulsion system that uses pulses of superheated plasma to generate a lot of thrust very efficiently. It's currently in phase two of development, funded by the NASA Innovative Advanced Concepts (NIAC) Program.

    This phase two study is scheduled to begin this month, and is focused on optimizing the engine design, performing proof-of-concept experiments, and designing a PPR-powered, shielded spaceship for human missions to Mars .

    The big advantage of the PPR is that it can make a spacecraft go really, really fast. It has both a high thrust and high specific impulse. Specific impulse is how quickly a rocket engine generates thrust, and thrust is the force that moves the spacecraft along.

    The PPR generates 10,000 newtons of thrust at a specific impulse of 5,000 seconds. That means a PPR-equipped spacecraft carrying four to six passengers could travel roughly 100,000 miles per hour, Howe told BI over email.

    The PPR rocket would have to slow down significantly to enter orbit around Mars and eventually land.

    A spacecraft flying that fast would eventually have to slow down to reach its destination. Howe said the company has accounted for the additional energy and propellant this would require to land on Mars.

    Even after phase two is complete, it will still be about a couple of decades before the PPR is ready to blast astronauts off to the red planet. But once it's available for spaceflight, Howe hopes that this technology will significantly expand the range of human space exploration , perhaps even aiding missions to Pluto one day.

    "You can pretty much achieve anything you want in the solar system once we get this technology running in 20 years," he said.

    It taking too long for this project, that should be done within few years, beware, China could develop something similar to this, so we must hurry up !
