They did NOT use 'light speed' ; Speed of Light'. Mankind has never created an object that will travel any where near the Speed of Light.
The Rocket blast off . It reaches a speed that will allow the spaceship to escape the Earth's gravity. After that it 'sling shot's' around other astronomic objects using their gravity.
Perhaps this will change with future advancements, but given our current knowledge no astronauts would ever reach the speed of light or even get close. One possibility for very extended journies would be something like the particle engines that are being developed. These engines (that put out a stream of sub-atomic particles) produce almost no thrust, but they can produce their low thrust non-stop for very long periods of time. After a few years, the results could be spectacular with fuel requirements that might be manageable. Then, coming to a stop would be the challenge. Imagine a massive engine failure, and watching your destination fly by at perhaps ten or twenty percent the speed of light. Disheartening to say the least.
1) No physical object, such as an astronaut, that normally moves at a slower speed, can move at the speed of light. It might be possible to approach the speed of light, but not quite reach it.
2) No technology is currently known that can speed up an astronaut (and his ship, of course) close to the speed of light.
3) Any such technology could be called an "engine".
Anything that pushes a spaceship would probably be called an "engine". An astronaut could never "get up to light speed". Light speed could be approached in theory, but not reached.
I believe that was (will be?) Zefram Cochrane, who invented (will invent?) the warp drive and make the first trans-FTL flight on April 5, 2063.
There is no possible way with the technology we have right now to get up to light speed your body would not be able to handle those kinds of speeds.
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
First of all, you would have to be dead to go to heaven or hell. So basically, the answers is no.
Using units such as the AU (within the Solar System) or the light-year or parsecs (for distances between stars, galaxies, etc.) results in numbers that are easier to grasp than meters or kilometers.
kill
yes they can use. they absorb energy from the light.
Sails that are pushed by light is one concept.
The technology to travel at or near the speed of light does not exist and is nowhere close to being developed. No astronaut or man-made object has travelled to other stars.
None. No astronaut or man-made object has ever gotten close to the speed of light. It is impossible for an object to actually travel at the speed of light.
They did not, so the question is misguided.
According to NASA, there are two reasons why astronauts wear white. First, white helps keep astronauts cool. Dark colors absorb a lot of light, which changes from light energy to heat energy.
Light pollution does not affect astronauts, it affects astronomers.
this thing dose not give u the answer!!!!!! does is spelled D-O-E-S smart 1
Astronauts
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.

The food of the astronauts is all packed dated and named , it special food light , as it can float in space.
