Yeah, you would only need to burn a little bit more on your initial burn, that’s why I said the cost would be similar.

It’s definitely harder to decay the orbit into the sun directly than it is to get to escape velocity. But to play devil’s advocate, there is probably a way to get them into the sun while being a similar cost to escape velocity. All you need to do is burn prograde to a super high aphelion, ride all the way out there to Pluto or whatever and then do a small retrograde burn to bring your perihelion inside the sun’s photosphere. When you then get back towards the sun years later you would slam into it with a sick velocity that I think would be worth the decades-long wait.
It’s just not true though, unless you do an out then in maneuver.
No that’s not really the case, the earth will be destroyed.
Technically there is no boundary, it’s atmosphere all the way in. But what we might call the “surface” is the photosphere. That is where the density becomes “low” (read not insanely high) enough that light can escape in a free path.
The sun has an atmosphere so there are soundwaves coming out of it. It’s actually all one big atmosphere getting thinner and thinner as you go out just like ours.
Website for pirating books. A godsend for me during university, where I saved 100s of dollars per semester, while getting the books in a digital format which I prefer.
Probably not, but the people who just got a job maybe would.
I mean if a state removed the TSA and spent the money on something else, surely they could use the money to create as many jobs as they removed but in an actual useful field.
Yes, it’s the avocado man himself in the picture.
If the arm can bend, the car and the magnet could move towards each other until they come together, moving the car at max a few centimeters. If the arm doesn’t bend, the car is pulled as much forward as the magnet, and therefore the arm and in turn the car itself, is pulled forward, leaving the whole system stationary.
No, because if it’s a proper planet it will clear its orbit.
Yes, but it’s not guaranteed that it will.
No, we only have one moon. I think the gravity of the moon is too large for other moons to be in a stable orbit around Earth.
The amount of time I spent going down into the deepest depths of LaTeX magic is probably larger than the amount of time spent on actual work for my master’s thesis.
It’s because it’s a very long image. Press the HD button in the top right corner, that should fix it.
As someone who does know about this field, and absolute despise Musk, that’s not quite true. SpaceX is very successful thanks to help from the US government, and despite the influence of Musk, but also because they are a team of very competent people who have actually innovated and pushed the boundaries of launch vehicles. To say they have nothing going for them and are being propped up by the government is not at all accurate, and they have been much more succesful than traditional government contractors.
Yeah they aren’t a unit in the sense that they make a non-quantifiable measure quantifiable. In dimensional analysis they would have the dimension [1]. But they can still be regarded as a unit since they act in the exact same way, just like other factors do. But yeah, they are more akin to the SI prefixes like kilo, or something like a dozen or a gross.
Yeah it probably is, my comment was really about raw deltaV numbers without using gravity assists.
