What did the first astronauts use to get up to light speed instead of engines?

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.

∙ 13y agoPerhaps 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.

∙ 10y ago1) 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".

∙ 12y agoAnything 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.

∙ 14y agoI 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.

∙ 9y agoThere 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.

What travels at light speed besides engines?
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
If you were alive and went to heaven would you feel gravity like the astronauts if you went at or faster than the speed of light?
First of all, you would have to be dead to go to heaven or hell. So basically, the answers is no.
Why do astronauts use AU instead of kilometers?
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.
What happens when light moves from a solid to a liquid?
kill
Can plants use artificial light instead of sunlight?
yes they can use. they absorb energy from the light.
What might the astronauts use to get up to light speed instead of engines?
Sails that are pushed by light is one concept.
What did the first astronauts use to get light speed to travel distant stars instead of engines?
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.
What would the first astronauts use to get up to light speed in stead of engines?
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.
How did first astronauts get to light speed?
They did not, so the question is misguided.
Why aren't astronauts spacesuits black?
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.
How does light pollution harm astronauts?
Light pollution does not affect astronauts, it affects astronomers.
What did the astronauts use to get up to the speed of light only in stead of engines?
this thing dose not give u the answer!!!!!! does is spelled D-O-E-S smart 1
Who discovered light pollution?
Astronauts
What inspired Edison to invent the light bulb?
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.
What encouraged Thomas a Edison to invent the light?
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.
Food astronauts eat?
The food of the astronauts is all packed dated and named , it special food light , as it can float in space.
Where does the light come from to let the astronauts see the earth?
The sun.
