Does NASA reuse shuttles?
All of the components are reused except for the external fuel tank, which burns up in the atmosphere after each launch. The longest the Shuttle has stayed in orbit on any single mission is 17.5 days on mission STS-80 in November 1996.
How long does it take NASA to build a space shuttle?
Will it carry people or not? A ‘simple’ rocket, like the falcon 9 from SpaceX, may take 18 months to make, but one that can take people into outer space, like the shuttle, can take 5 years to make, start to finish.
Do astronauts pass out during re-entry?
This causes a temporary drop in blood pressure, which can lead to dizziness or fainting. “One of the biggest problems since the inception of the manned space program has been that astronauts have fainted when they came down to Earth.
Can a human survive reentry?
yeah, you could drop straight down without massive amounts of heating due to atmospheric friction. But you can’t, so you need a heck of a lot of heat shielding, and eventually some specialized chutes to slow you down and then bring you down in on piece.
How many Gs do astronauts feel during re-entry?
On shuttle reentry, the forces put on the body as the craft decelerated through the atmosphere were only 1.7 Gs, and usually just a normal 1 G or so.
How many G’s is a fighter jet?
How many G’s until you pass out?
A typical person can handle about 5 g0 (49 m/s2) (meaning some people might pass out when riding a higher-g roller coaster, which in some cases exceeds this point) before losing consciousness, but through the combination of special g-suits and efforts to strain muscles—both of which act to force blood back into the …
Do fighter pilots wear diapers?
They have little pee bags containing a material that absorbs urine. They just pee in the them and stick them to the side. Or, they can wear adult diapers.
How fast is 9 G’s in mph?
Please share if you found this tool useful:
|8 Standard Gravity to Miles Per Hour Per Second = 175.4948||500 Standard Gravity to Miles Per Hour Per Second = 10968.4256|
|9 Standard Gravity to Miles Per Hour Per Second = 197.4317||600 Standard Gravity to Miles Per Hour Per Second = 13162.1108|
How many G is 700 mph?
With acceleration at 0.3g, reaching 700 mph may only require 15 kilometers, or around nine miles, of track.
What’s the fastest thing in the human body?
Whats the fastest we can travel in space?
We believe in the free flow of information It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.
Can humans travel light speed?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
Will we ever travel faster than light?
Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.
Can you accelerate forever in space?
Due to the distorting effects of the theory of relativity on space and time, you can keep accelerating at a constant acceleration forever, and yet never hit the speed of light.
Why do the ships on the expanse fly backwards?
Whenever a ship is traveling to a certain destination, it has to cut thrust and flip around halfway through the trip. The back half of the journey is then spent with the main drive pointing toward the destination in order to decelerate.
Is artificial gravity possible without spinning?
In science fiction, artificial gravity (or cancellation of gravity) or “paragravity” is sometimes present in spacecraft that are neither rotating nor accelerating. At present, there is no confirmed technique that can simulate gravity other than actual mass or acceleration.
What happened to Alex in the expanse?
Why Alex Died In The Season Finale He discloses to Naomi (and viewers) that Alex was killed by a stroke, reiterating out loud that this is a risk everyone takes when they travel in space.
Does the expanse have artificial gravity?
In the Expanse series by James S. A. Corey, space stations generate artificial gravity by rotating, as do spun-up, hollowed-out asteroids, usually at around 0.3 g. Moving ships under constant thrust also simulate gravity by linear acceleration.
Why are there no lasers in the expanse?
I remember, that engineer warns that this laser will melt to slag after a few seconds, but it is because this weapon is made basically from scraps. There is also no problem with power, since each ship is equipped with a large fusion reactor.
Why are there no fighters in the expanse?
They’re more like a modern coastal patrol craft, and probably have smaller armament and no quarters/arsenal for a complement of marines. In almost all sci-fi, fighters exist more because they are cool than because they would actually make sense. And since The Expanse tries to be realistic, it therefore has no fighters.
How fast can the ships in the expanse go?
So Rocinante’s maximum practical speed is 2,750 km/sec, if it wants to come to a stop at the target. At 1 G, which seems to be the standard acceleration in Expanse universe, a ship takes 78 hours to reach 2,750 km/sec. During these 78 hours it will travel 386 million km.
How realistic is the expanse?
Unlike “Star Wars,” where characters out in space can communicate with one another in real time via holograms, “The Expanse” depicts a lag in communications. That’s also pretty realistic. “Communications are not faster than the speed of light,” Filippenko said.
