Hasn't this been like a working theory since the 50's or something and never went anywhere?

> It would also make the journey to Mars significantly shorter, from six months to just 45 days.

What about a mission to places like Neptune?

So, now we have to bring an atmosphere with our ships???

A rocket is simply a controlled, continuous explosion.

Deaths will lead to revisions and maybe redesigns, but it won't stop anything, it's just a risk that's inherent to the kind of propulsion we use, and the environment we are sending people to.

I attended one in the early 90s. My dad taught one of the astronauts physics when he was in highschool, so we got to watch from the family and friends platform. It was incredible. Highly recommended.

Integza also did a really good video on it. He visited a test bed engine to see how powerful it was.

This is good advice. I would add Orlando is a nightmare to me and some people would have more fun staying in St Augustine, or even Savannah. Since you will be spending good time in a rental, splurge for a van or large SUV. I would fly into Tampa or Jacksonville if it saved me $500 on tickets and/or car rental.

After the launch, drive that badboy down to key west and experience one of the greatest American road trips. Your family will never forget it.

This title is wrong by a factor of ten.* This asteroid came within 25,000 miles, not 2,000.

*It's not wrong. The article had another number I took at face value.

Edit: I stand corrected. Fascinating stuff! Thanks for the corrections.

Indeed it is. And there is a third on the right.

I was about to say, if you tried breathing on a habitable planet you'd probably inhale some super toxic or deadly stuff almost immediately. You would 100% need an extremely reliable and high quality filter to make the air safe to breathe even if it's the same composition as on Earth.

Multiple generations of humans would need to gradually develop immunity to the planet's natural threats, unless we could make some insane tech to compensate for it

At least there are a lot of launches these days, so you can target dates with some potential. I travel to the Space Coast of FL quite a bit. Best thing to do is to simply be aware of the schedules: https://spaceflightnow.com/launch-schedule/

Then plan your dates. Then hope. Last time I was down I really hoped to see the Falcon Heavy launch and two boosters land. It was scheduled for about 3:00 AM and night launches are super cool. Thought I would get to see two booster landings at night. They scrubbed three times in a row.... no luck. While I was there I did see a F9 launch during the day.

FL vacation is not easy or cheap. You can watch from anywhere nearby on the beaches, but Titusville or the Space Center itself is best. Cocoa Beach anywhere at the pier or North is great. Jetty Park is fantastic. You can always stay somewhere between the Cape and Orlando to save on cost, then make some Orland visits to tourism land.

So dusting off the Orion project plans?

I'm writing a textbook on Space Systems Engineering. Check the "view history" tab on any page to see who wrote it.

>according to your claim 18x more H2 coming out the ass, is that true?

That's your number, not mine, and it is wrong.

>Oh, twice huh. H2 weighs 2 grams per mole, it will need to be ejected at nine times the velocity of a water molecule at 18 g/mol to have equal the force.

Or just with 9x the mass flow rate. And thrust doesn't matter too much in space, what matters is fuel efficiency. A weaker nuclear rocker might need to do longer burns, but for the same mass of fuel as a conventional engine, it will get you going a lot further.

No, because I don’t really want to wait around days or weeks until it actually launches

Local here. Do not plan a launch as your primary visit to Central Florida. The Kennedy Space Center does have a very cool tour, which will undoubtedly be very crowded surrounding a launch date. There are other attractions in the Central Florida area as well, including beaches, theme parks, reserves, and state parks.

Plan your visit around the launch. Make plenty of time to be there for it. You won't get as close as the TV reporters or VIP spectators do, but you will be close enough. There are plenty of beach and intercostal parks that have very good viewing points for a launch. Leave yourself a lot of buffer time around a launch, as traffic is pretty horrible during those timeframes.

There are no refunds on anything from anybody.

You're not going to be paying KSC to watch the launch. You're most likely going to be in a water side park or even a parking lot.

If you come solely for a launch and it's scrubbed, now you're miserable.

My advice is to come visit Central Florida during a launch window , pack a cooler and head to the coast for it. If it's a clear day, you can see the flames from the boosters from Orlando very easily. On good days, you can watch the SpaceX boosters come back down as well.

If the launch is scrubbed, you're pretty much at the beach, so spend the day there with the family. If it isn't scrubbed, watch the launch and then spend the day at the beach with the family.

It's a long wait for a relatively short window, but it's totally worth it. Just make it a potential highlight of your visit and everything will be fine

I really want to but it seems like a huge gamble trying to schedule vacation time around such a variable thing.
