    > NASA has announced it will launch a nuclear-powered spacecraft to Mars before the end of 2028. The effort would mark a world first—no interplanetary spacecraft mission has ever been powered by nuclear propulsion before—and a massive boost for potential missions that would go farther out into space and travel faster than traditional liquid-fueled craft could manage.

    > The space agency plans to the launch the spacecraft, called Space Reactor-1 Freedom, to the Red Planet, where it will deploy several helicopters to explore the surface. The helicopters, NASA said in a statement, will be modeled on Ingenuity, which flew as part of the Perseverance Mars rover’s mission on the planet.

    >According to NASA, the mission will prove nuclear propulsion can power spacecraft “and activate the industrial base for future fission power systems across propulsion, surface, and long-duration missions.” These could include missions to planets and other bodies in the outer solar system. Currently, exploring these distant worlds would be impossible with traditional craft, which would require massive amounts of liquid fuel to travel such distances. Only spacecraft that are small enough to be battery- or solar-powered, such as the Voyager and Juno missions, have reached these outer realms of our solar system.

    >Nuclear propulsion has long been touted as the solution to this problem, but it has never been proven to work in a mission. It is unclear what propulsion design NASA would use to test the system or if there will be any collaboration with industry.

  2. I’m announcing that Scarlett Johansson dumped her zero husband and will be dating me.

  3. “Space reactor-1 Freedom”

    God, a wealth of names to pick and _that’s_ what they settled on?

    Two and a half years to design, build, test, and deploy a wholly novel propulsion system? Pull the other one.

  5. I don’t think we should just be brainstorming random interplanetary science mission concepts and slamming them into the budget while picking some enormously unrealistic timeline out of thin air. This has reduced a lot of whatever confidence I had in Isaacman as an administrator. Interplanetary science missions should be founded on a firm science and engineering basis and they should go through a competitive review process. That’s substantially why we have had so much success over the years and have achieved so much great science. These aren’t just toys to play with, these are serious endeavors.

  6. It’s just so annoying to see these things and have to tell yourself every time: at best this happens in 2030, and there’s a 40% chance it gets cancelled

    Can’t trust plans or dates anymore

    Is it nuclear-electric or nuclear thermal like the cancelled DRACO NASA-DARPA demo?

  8. I very, very, very strongly doubt that, given they cancelled DRACO at the start of 2025, which was meant to be the big leap in nuclear rockets, approximately 30 minutes before it was meant to launch.

    I know DRACO was NTP, and this is NEP, but that’s still really not a good sign.

    (Full disclosure, I was a scientist working on NTP that lost their funding, so I’m very bitter)

    Bullshit. There is no way the can pull that off in such a short time period. ESPECIALLY considering the cuts to the science programs.

  10. It seems to me that NASA is starting with a date, 2028, and then defining new or modified projects that will have its first meaningful launch by that date. It is almost like doing it prior to the end of 2028 increases their chance of getting the project approved. I wonder which person, with the power to affect NASA’s budget, would desire an expensive NASA project complete a major, “hey look what I did”, milestone before the end of 20208. A real puzzler.

    It doesn’t surprise me when the remaining Pu238 supply for RTGs is basically nonexistent at this point.

  12. So we are going to the moon and building a base, going to Mars…….Meanwhile we can’t even pay our TSA agents, fund security for the World Cup and build a ballroom….

    They are trying to get our best and brightest killed tragically in front of the whole world. Everything Trump touches dies.

    Announcing grand plans is all fine and good, but the real trick is getting Congress to fund it.

    And that will be the true test of Jared Isaacman’s administration.

  16. So Trump effectively cancels DARPA’s existing nuclear propulsion program last year, and now it’s being revived again a year later?

    Fucking hell, this administration is just a constant whirlwind of batshittery.

  17. DinerEnBlanc on

    If it happens in 2028, they’ll just be launching a bunch of people in a coffin into space.

  18. Absolute farce. We have got to stop handing our future in space over to payment processing tycoons whose worldview seems to be driven by a semi-literate reading of sci-fi Spark Notes.

  19. Elevated_Dongers on

    This is like they made my senior design project a reality. Lots of theoretical assumptions and an insane budget.

  20. the-software-man on

    Nasa is lost and seems to have no direction. Picking new targets every 6 months is bad. Picking new targets and with new tech in short test frames is really bad. New-clear propulsion.

  21. Sorry_about_that_x99 on

    Is this some kind of joke? Is Issac taking notes from Elon’s empty forecasts and false promises? Oh wait, of course he is.

  22. This idea is from the same people thinking data centers in space is also a good idea

  23. Odd_Photograph_7591 on

    Another chapter in NASA’s ever changing goals and projects, stay tuned😊

  24. All announcements, no actions. Especially with dates the current administration won’t have to deal with.

  25. We are not the same, I am a Martian
    And I’m hotter than summer rain like Carl Thomas
    Lock, load, ready to aim at any target
    I could get your brains for a bargain like I bought it from Target
    Hip-hop is my supermarket
    Shopping cart full of fake hip-hop artists
    I’m starving, sorry, I gotta eat all it
    And I’ll be back in the morning

    Uh, no. There is a reason we haven’t done this before. A nuclear space craft would be the world’s largest dirty bomb. If the craft fails, that’s an expensive loss, but if it explodes as part of that failure, that’s radioactive material getting spread around the world.
