## How fast can Rockets go in space?

How fast can conventional rockets go?
Flight Plan speed required

Earth to Earth escape 24,200 mph
Earth to lunar orbit 25,700 mph
Earth to GEO (geosynchronous Earth orbit) 26,400 mph

## How fast can we travel in space with current technology?

At 1 percent the speed of light, it would take a little over a second to get from Los Angeles to New York. Light is fast. In fact, it is the fastest thing that exists, and a law of the universe is that nothing can move faster than light.

## How fast does spacex travel in mph?

The Falcon 9 rocket accelerated the Crew Dragon capsule to a speed of some 17,000 mph (27,400 kilometers per hour) to reach orbital velocity. That’s equivalent to traveling 5 miles every second. That speed will keep the spacecraft in space for three days, when the Inspiration4 mission will come back to Earth.

## How long is 1 hour in space?

The cosmic clock never budged from its birth place; we have and when we return, we are like the twin astronaut, younger than his Earth brother.) That number times 1 hour is 0.0026 seconds.

## How fast can a human go without dying?

This is a well documented field, and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. However this limit depends on the individual, whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.

## Will warp speed ever be possible?

Outside of that, even greater speeds appear to be possible. “None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

## How is 1 hour 7 years in space?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

## How much do astronauts get paid?

The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at \$64,724 per year; a GS-14 astronaut can earn up to \$141,715 in annual salary [source: NASA].

## How long is 24 hours on the moon?

The short answer is this: A day is the length of time between two noons or sunsets. That’s 24 hours on Earth, 708.7 hours (29.53 Earth days) on the Moon.

## How long is 1 second in space?

The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

## How long is a day on Mars?

1d 0h 37m
Mars/Length of day

## What does space smell like?

Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …

## What happens if you spend 5 years in space?

If you mean after 5 years in space, upon arrival back on Earth everyone will be 50 years older.

## How cold is space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

## Has anyone been lost in space?

Originally Answered: Has anyone ever been lost in space? No. People have died training for space, trying to get into space, and returning from space but nobody has really died in space. The one incident that technically happened in space was Soyuz 11, in which a vent valve opened and caused depressurization.

## How many deceased bodies are in space?

Only 3 people have died in space: Georgi Dobrovolski, Viktor Patsayev, and Vladislav Volkov. 3 cosmonauts on the Soyuz 11 mission who died in 1971 when returning from a Soviet space station. Their return capsule suffered an accidental decompression.

## Why did NASA stop going to the Moon?

But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.

## Do you get younger in space?

Background. Astronauts age a bit slower than those of us on Earth due to something called “time dilation” described by Einstein’s theory of relativity.

## Do you age in space?

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

## Has anyone been born in space?

It’s plausible that this idea could be extended, with a wealthy couple booking a long-term stay for the entire process from conception to birth in orbit. At the moment, there’s no evidence anyone has had relationship in space.

## What happens if an astronaut floats off in space?

If an astronaut floating away from his spaceship he ends up orbiting around Earth by the gravity force until he runs out of oxygen or some debris from the space hits him and causes to tore up his suit. To avoid this from happening the international space station follows strict rules.

## Can humans survive without gravity?

It might seem like a fantasy to float weightlessly through the air but practically, the human body would go through negative change, such as muscle and bone atrophy while living in zero gravity. Even the rivers, lakes and oceans on Earth wouldn’t stand in zero gravity, without which humans cannot survive.
