Did astronauts visit Neptune?
No. Astronauts have never been anywhere near any astronomical bodies except Earth and the Moon.
What is the ratio of men to women astronauts?
Women make up 18 percent of all the active astronauts working today. this would mean 6 out of every 35 astronauts are female.
What happens to astronauts bodies in space?
Their bodies would become very weak.
What two things produced by plants would be important to keep astronauts alive on a long jouney to Mars?
The two things produces by plants that would be important to keep astronauts alive on a long journey would be glucose and oxygen. Oxygen is most important.
How long would it take to send a crew of four astronauts to mars?
7 months
How did astronauts know where to look for Neptune?
Yes. Typically one looks to the sky to view Neptune.
How many astronauts have visited Neptune?
There have , as of yet , been none .
Did astronauts visit Neptune?
No. Astronauts have never been anywhere near any astronomical bodies except Earth and the Moon.
What are the names of the astronAUT that went to Neptune?
There have been no astronauts that have gone to Neptune. Nor is there any space exploration projects or programs called Neptune that I am aware of.
Why has nobody explored Neptune?
it is too far out and it is too cold and astronauts don't have enough oxygen
How many times have astronauts visited Neptune?
None. No astronaut has gone farther than the moon. Neptune is murch farther away. Only one unmanned probe has visited Neptune: Voyager 2.
Did astronauts go to Neptune?
Not until we develop hundreds of years worth of technology. Currently, man-made space shuttles are not designed for long-term space travel. At best, they are designed for orbiting our own planet and the moon. To be able to visit Neptune, it would take years to develop a shuttle capable of travelling out that far. Then it will take a matter of more years to actually get to the planet since it is so far away. There is also the issue of temperature. Neptune is absolutely freezing, currently, any human who gets close to Neptune would freeze in seconds. Electrical equipment such as surface exploration drones and landing space shuttles would freeze and malfunction. So, with our current technology, no, astronauts cannot even get close to Neptune. However, Neptune can be explored with orbital unmanned satellites.
What would happen if Neptune was as close to Earth as the moon?
Earth would either orbit Neptune or get torn apart by neptune's gravity
Why hasn't anyone landed on Neptune?
There are two reasons: Neptune is too far away and the environment on Neptune's surface wouldn't allow the astronauts that land there to survive. Distance: In astronomy a unit called Astronomical Units (AU) is sometimes used to measure distances; one AU is the average distance from Earth to the Sun. Neptune is 30 AU away from the Sun. To reach Neptune in a space craft traveling 11.2 km per second (which is how fast you must go to escape earth's orbit) you would need to travel for 12 years and there are also many other complications. How will the astronauts get food and water? Do we send them up with 12 years worth of food and water? They'll also need another 18 years worth of food to sustain them while they are actually at Neptune and on their way back. How much fuel will they need? Most likely more fuel that human beings have ever produced in history. How will they get oxygen? We have no idea how much oxygen they'll need, and still it will add more weight, which will require more fuel to move. How will the people on Earth communicate with them? Neptune is four light-hours aways, meaning that any communication between Neptune and Earth will take 4 hours one-way or 8 hours round-trip. Also, will the astronauts themselves survive? Over the course of 12 years the risk of the astronauts dying before they get to there destination goes up. We have no experience with sending people on a space mission that will take over 24 years. Neptune's Surface: The surface of Neptune is another impossible obstacle when it comes to landing on Neptune. Neptune's surface is covered in ice and glaciers; there also an atmosphere consisting of ammonia, methane, and helium. Neptune also has a thick atmosphere and there are constant violent storms on the surface. One such storm, known as the "Great Dark Spot" is the size of the Earth! Neptune's environment would completely prevent any space trips to Neptune within the foreseeable future.
Would a human survive Neptune?
No 1 can survive on neptune
What would it cost to go to Neptune if you went to Neptune?
$1.89
How many astronauts do you think would fly together in the command module?
Three astronauts
