    For Questions That Don't Merit Their Own Thread

    Ignoring money and ethics (Although, I don't really see it as unethical to use Nuclear in space considering there's no life)? You're right about Orion giving you around ~10% light speed, but I don't ever remember seeing 20% (Except now that I remember, I do remember some Ben-10 episode talking about Orion getting that high, but I wouldn't call that a reliable source ). 20% may be possible for something akin to Daedalus, but not Orion. And Daedalus definitely isn't possible with current technology. If we were really serious, I suppose we could start the research for that, but it'd probably take decades. The caveat for Orion is that you're only going to see about ~5% light speed if you want to slow down. So that's 90 years to the nearest star. Not horrible, but not really fast either. With current technology, anything we build will be limited by nuclear fission. If we had fusion, our options would be pretty large, but alas. In this list, you can see a lot of options. I believe you want your specific impulse in the (high) hundreds of thousands of seconds - or higher - to be viable for an interstellar drive http://www.projectrho.com/public_html/rocket/enginelist.php#werkaffre If you want to coast to the nearest star using current technology to around ~5-10% light speed, a combination of laser sails and nuclear pulse propulsion, or (maybe?) nuclear salt water would be your best bet. And here we begin with starshot. Ignoring the fact I don't know if its possible to have a postage stamp sized spacecraft that can last decades; the basic idea of using a massive laser array to push a solar sail is a good one, and has been around for decades (Scroll down http://www.projectrho.com/public_html/rocket/slowerlight.php). You could get pretty impressive velocities too, at least 0.1-0.2c (or ~40-20 years to the nearest star. Now we're talking). But the catch is that there's no laser on the other end, so you'd be limited by your maximum velocity to something manageable (<.1c) by your drive (AKA, Orion), until you can build a laser array on the other end to catch your ship. You could also slow down using the solar wind of the target star, but I don't think it'd slow you down a whole lot to be done alone. Going back to a fusion drive in general (http://www.projectrho.com/public_html/rocket/realdesignsfusion.php), you might be able to get away with it if it's powered by a new generation nuclear fission reactor. However, I don't know how inefficient/ineffective that would be. Or if a design could match or exceed 5% the speed of light. Someone more knowledgeable will have to answer that. Finally, using current technology to build a starship would be hard, and if crewed, dangerous. I'd bet that if we started on one today, it would be delayed by things we hadn't considered, and require technology later down the line. But I would also say we have most of the base technology already. So we're in an ok position to begin. I'd try to account for the wait calculation though
  2. Like, how hard it'd be to use in the first place?
  3. Er, context please? (I only got up recently )

    How to mark forum as unread

    Yeah, I pressed that too It was a while ago, so I have to go a couple dozen pages back to see the unread-but-not-really-unread-posts now. I'm pretty sure I asked then too, there's no way to undo it.
  5. Yeah, but this is nuclear pulse propulsion you're talking about. A spacecraft that uses at least thousands of nukes onboard for propulsion. Some early designs were for the military for massive battleships. There would be worries about military contracts for that technology. No matter your intentions, people would be wary, and I wouldn't be surprised if it quickly became an international matter. Getting permission to build even one ship would be a tremendous undertaking. True. Plus, we would need a lot of research on autonomous spacecraft, that can make smart decisions, and work properly for decades, or centuries. And spacecraft that can last a very long time without breaking down, or at least, can repair themselves.
  6. Only way I can see us doing that is if someone like Musk or Bezo's figures out how to get around the outer space treaty/nuclear test ban treaty, and builds it in space, far from Earth. But by the time we're capable of that, I'd hazard a guess to say we'd have access to something better. That 2013 design for a fusion engine seemed promising, and would lead to more powerful drives, whatever happened to that?

    *Reads last one* Good to know I'm not the only one who does that. *In response to 0111narwhalz No, I don't do that. User below me knows/is learning a programming language.

    That must've been a real pucker factor there... Glad to hear the Astronauts are okay.

    True. If I did, I probably would've considered myself to have peaked. The user below me has been camping before (As in, no RV's, all gear and equipment in backpacks, etc).

    My SciFi/Fantasy novel idea list

    Ok, keep in mind, I'm very early in this. Infinitum and The children between worlds have to come first before I start planning that, so the plot may be different in a few months or something like that.

    My SciFi/Fantasy novel idea list

    Kinda, I guess. Once it has a foothold, it spreads fast. Some hit population centers, etc, and no one is really sure whether they should nuke it (That'll be a conflict in itself). Yeah, you're right. I did say it was subject to change. Humanity is in the middle of colonizing Mars when it happens, may as well continue if the Earth may become uninhabitable. And yeah, they also begin to construct a fleet around Mars to protect it. If we're desperate, and have the technology, I'd argue that we would devote more time and resources to space exploration. And maybe not a few million people, but you could probably do a few hundred thousand at the least with the time given. Assuming not much goes wrong. Each BFR could do up to 100 people. If you have a lot of engineers, and prior experience using them, you could build up fairly quickly. Many of them would go to the Moon anyway. Plus, like I said, they've got around several decades before they enter the solar system.

    Yeah Watching this right now

    Damn, that bottom pic looks like something striaght out of a sci-fi movie.

    My SciFi/Fantasy novel idea list

    Working on a new plot for the Children between Worlds and Infinitum. I'll be doing the Children between Worlds during NaNoWriMo, and however long it takes after to finish the first draft. Then I'll start Infinitum again. It's been awhile... @ChrisSpace Didn't want to derail NSEP's thread, but here's a basic premise... that may be changed In the near future, a large amount of an unknown substance hits the ocean at high velocity. Scientists worldwide celebrate the discovery as proof of extraterrestrial life, but within a few months, they find it's hijacking, and changing the ecosystem. Several more of these hit the Earth over the following year, and they conclude the Earth must be being terraformed. They look in the direction where it came from, and see traces of what look to be ships, moving towards Earth. Everyone goes into high alert, and humanity begins constructing a fleet of their own around the Earth and Moon, as well as the Mars colony. Millions of people are shipped off Earth to give humans a chance. Spoilers about the aliens.
