Science Saturday OT: Why Rocket Science is as Hard as Rocket Science

 134 replies

Tony does his best to make you smarter, despite the comments section.

Rocket science is hard, everybody knows that. But what is it about putting stuff into space that’s so hard? The answer is complicated, but the short answer is escape velocity.

Think about throwing a ball straight into the air. As it gets higher in the air it moves slower and slower as the force of Earth’s gravity pulls it back down until it succumbs and starts to fall back to Earth again. Gravity does start to get weaker as you get further away from Earth, but that drop in gravitational pull is not nearly as much as the drop in speed of the ball, so a ball thrown by a normal human can’t escape the Earth’s gravity well.

To get to space you need to be moving at a high enough speed that the decrease in your speed is less than the decrease in the Earth’s gravity, and the speed necessary to do this is very easy to figure out with a simple equation. Just multiply the mass of the Earth by 2, multiply again by the gravitational constant, divide by the radius of the Earth (i.e. you get a head start the further away you are from the center), then take the square root of that. So let’s do that.

And the answer is 23,000 miles per hour, or almost 7 miles per second. That’s really really fast. How on Earth do you get something to move that fast? To put it simply, a very large, controlled explosion. In other words a rocket engine.

As you can imagine this is difficult to do. You need to not only design the engine so that it can withstand the tremendous forces being applied to it, but you need to carefully control the chemical reaction so that the entire fuel supply doesn’t explode all at once. On top of that you begin to run into a weight problem. The faster you need to go the more fuel you’ll need, but adding more fuel makes the rocket heavier, requiring more fuel to make it go, with more fuel making the rocket heavier, requiring more fuel to make it go, with more fuel making the rocket heavier, you get the idea.

Of course all of that just gets a thing into space. If you want to put that thing into orbit (like if it’s a satellite) or put a person on the Moon and get them back alive then getting up to escape velocity is just the beginning of your problems.

I occasionally rant about “deliberate stupidity”, or stupidity by choice, and SciManDan has found an outstanding example of this. Guy babbling on about the “dome over the Earth”, and what’s the first thing he does? Tosses all science out the window and focuses on the Bible, including books that were not included in the canon established by the Council of Nicea. And he talks as though the KJV was literally the way each book was set down by God, but “heaven” and “hell” were not even words at the time the writings ended, let alone begun. Any straw he can grasp that seems support his predetermined conclusion, he snatches, while ignoring that if this “dome” is some 600mi (or whatever his ko0kmath result was) away, there’s no way early man could have constructed anything even a mere mile high. But his “Tower of Babel” claim is that they could have built that high came first, so it can be conveniently forgotten while doing his calculations at the end. Drives me nuts, but starting at a conclusion and then finding ways to ignore any contrary evidence while seeming to prop their idea up is one of the unifying factors of all conspiracy theories. As I said at the beginning, he chose to be stupid, and now his intelligence is a tool for making himself dumber.

What, unanimously?

For spiritual matters I won’t condemn the whole thing outright, and historically it is sometimes accurate enough, considering. It’s a good read if you’re philosophically-minded, too, but as a source of scientific data it’s got nothing.

God most certainly did not stop the Earth’s rotation for a day and then have it resume. A stop and start of Earth’s rotation would have had to have left traces in many ways, and I suspect it would cause a global disaster. Unless, of course, you invoke magic, in which case you can say anything you like – but you can’t prove a damn thing then.

Come on BRaG, you know evertime God moved in the Bible, the action was impossible. From the very beginning to the very end, everything He did was impossible. So picking out one event is kinda meaningless. If the Bible is true (I know you don’t believe), it’s His creation and can do pretty much anything He wants with it.

If the KJV translations do not match better source material and includes translation errors and editotial changes as well, that has nothing to do with the reader and everything to do with the translators.

And actually, physicists have considered if the universe is nothing more than a simulation. Religions will not.

My life would have been much simpler if Christians hadn’t treated me so very badly at times. If God was punishing me for mental illness it doesn’t say good things about him. And if he had a plan for me, his plan was to deliberately drive me away with his followers, followed by eternal torment that he could stop, but sadistically won’t. Not that I believe in hell, and the Bible doesn’t support modern beliefs about “place” at all.

I’m so sorry for the pain you experienced, people can be such jerks. You’re not the only one that suffered at the hands of so-called Christians. My son was picked on when he was young at church because of his learning disability and communication skills. Christians certainly make it hard to believe in Christ, that’s for sure.

Outside perhaps an atheist stranger or two have harmed me, but outside that not one person of any other faith has done so.

Meanwhile, I don’t mean random assholes, I’m talking congregations here. THe last one involved a falsely-stated request to pray for me as an excuse for my ride and her friend to preach at me, and when I told them they were harming me – and in public, mind you – which goes directly against Jesus’ orders about prayer – they doubled down until I had to walk away to escape. I was very psychologically vulnerable at the time, but they cared about me as much as their god did, not at all.

Science, however, has actively supported and helped me along the way. Left to the clutches of Christian churches I would have committed suicide decades ago, but they feel no more responsibility than they believe God lacks.

No, actually, though I’m generally familiar with that text.

The Church(es) have also messed with the understanding of the text for mysoginistic reasons, turning Mary Magdalene into the woman at the well (aka prostitute, to them) and de-emphasizing all the female church leaders, sometimes arbitrarily altering their names from a feminine form to a masculine one.

This has been verified in older versions. Is God a mysoginist, who decided to allow humans to mess with His Sacred Word to that end? Why didn’t He stop them, indifference?

That’s faith, and while you are correct that I don’t hold with organized religion, the Bible cannot possibly debunk science. If God created the universe, etc, the way described in it, then God’s deliberately playing deceitful games with us. In my words, pissing down the back of my neck and telling me it’s raining.

Folks can believe in magic, miracles, astrology or whatever, science is based on the observable universe and one contrary fact can alter scientific theory. Invoke magic and no amount of facts will change your mind or stop you from misleading others with non-Biblical woo “theories” while denying all facts to the contrary.

Is God playing fair with us, or messing with us so preachers can get paid?

I know you bowed out, but still want to drop this here: If “God’s miracles” account for everything that varies from the Bible, then you have to accept that God miraculously changed the Native Americans’ DNA so they no longer came from the Levant but from Asia. Or is it just one Chrisitian sect that gets to use that excuse, and if so, which one?

Also, that means that God is a being who feels no responsibility for anything, no matter how evil. It’s His game and he doesn’t have to play nice. It’s his plan, and his plan includes untold horrors. Why? He wants it that way so he can punish most of humanity for all time. Sadistic.

I know you’ve been hurt by the church, I don’t want to add your bad experience with christians. Will try to respond to this comment accordingly. Can’t answer the DNA question, never heard that one. Regarding hell, haven’t heard a good answer for that question from anyone, but it does tie into your question of responsibility. I look to the Cross for those answers. He took our sins upon Himself and nailed them to that Cross. Seems to me that is taking responsibility for His creation and provided a way out from judgement. Being judged and condemned by God is what leads to hell. He gave us a way out. Again BRaG, I’m sorry for the way you were treated and hope you can forgive us.

I’m not of a believer these days, but when I did, I always thought he did things according to the natural laws of the universe. I never thought the things he did were impossible. It just seemed that way from the perspective of the writers, who had no knowledge of what he might be doing and described things the best way they could. Add in some mistranslations and embellishments over the centuries and you get the Bible.

Not for 1 sec do I believe “black budget” is using this same stone age technique from the mid/late 1940’s. Many people say….black budget technology are 40 to 50 years ahead of our current…but for you & I…we only see – today’s technology.

Let this sink in:
how many connected devices by 2030 per person = 15
how many connected devices by 2040 per person = 1000

Only thing holding us back there is a strong enough cable with minimal stretch to it. How that would be made, I dunno, but maybe something like carbon nanotubes combined with synthetic spider silk.

Heinlein postulated magnetic accelerator rings as an assist, but alas, that will have to await fusion reactors, due to the power needed. And even then that much magnetism might well seriously fuck with wildlife. So we’ll have to wait and see, but rockets are indeed a lousy way to achieve orbit.

I have some hope for warp drives. If we can get those working, we wouldn’t need rockets or space elevators.

This is (probably) crazy, but it seems to me like the US Navy’s videos could be of something with a warp drive. To be able to withstand the G’s they are going through along with effortless lift and speed, while in air or water, shows something acting warp-drivey to me.

I think that if someone on Earth was warping spacetime someone would have noticed, such as the LIGO-Virgo gravaty wave detection setup. Of course, that’s the best-case scenario, it could be incredibly destructive on the other end of the spectrum.

At the moment, all science sees there is a possible potential, we’ll see fusion reactors before we see anything like that in operation. Hell, you’d probably need a fusion reactor to power it, come to that. Logistically impossible, regardless of “black budgets” or whatever, not to mention we’d need a supply of unobtanium.

No, no, he was much smarter and better educated than I am. Hell of a writer, though. RIP, Dr. Asimov.

one of my all-time most favoritest short-story EVER ever … even Asimov himself regarded this as his best and favorite

Loved that one, too. His later Robots novels IMO he stretched too far, but the early ones were good. And there’s the Foundation trilogy, of course.

My first exposure to SF came in 1st grade, I believe (hard to remember that particular year, it was otherwise awful), with the Bammans’ series such as Ice Men of Rime or Space Pirate.

Not great science, but great stories nonetheless. And once the Bookmobile was available the llibrarian took a shine to me and I was in hog heaven.

I’m looking forward to the SpaceX Starship.

They plan on sending up multiple ships at a time. One will go up into orbit, then another will also go up and replenish the fuel of the main ship by connecting “butt to butt”. The the main ship will then be fully fueled and supplied for the next legs of trip to the Moon or Mars.

Saw yesterday that the prototype launched and successfully re-landed 150 meters away in the last few days. Not much, perhaps, but it wasn’t the distance they wanted, it’s the telemetry, the data. The SpaceX team were certainly thrilled by the flight, and IMO rightly so.

If you want to put that thing into orbit (like if it’s a satellite) or put a person on the Moon and get them back alive then getting up to escape velocity is just the beginning of your problems.

‘Escape velocity’ reminds me of when I jettisoned my ex-wife
