Astronaut John Young has been to space the most times, I think four times.
Hard to say, there have been so many. Sputnik was the first, and led to the space race between the USA and Russa.
The radio wavelength range has been the most fruitful in the search for organic molecules in space. Radio telescopes have detected complex organic molecules in regions such as star-forming regions, comets, and interstellar clouds, providing valuable insights into the presence and chemistry of organic molecules in space.
The planets that have the most space between them are mercury and Pluto.
The Hubble Space Telescope is the most famous and the best working EVER MADE!
There have been a number of scientists in space. Most US military officers have science or engineering degrees, which would include all but one of the Apollo astronauts. The one non-military person (so far!) to walk on the Moon was Harrison Schmitt, who was a geologist. Of the International Space Station crewmembers, many have been pure scientists.
Mars.
Sergei Krikalev (Russian) holds the record for the most time spent in space. He has spent a total of 803 days and 9 hours and 39 minutes in space.
Space debris is anything man-made that has been launched into space, but no longer has any function. Most debris is from parts of satellites/stations that have been ejected or that have fallen away.
If you value human life, the the many men and women who've gone up are the most important. There have also been many important scientific experiments to go into space. Arguably the most popular has been the Hubble Space Telescope which has given us photos of what the universe looked like from the beginning of time.
how long has Jupiter been in space
Up until about 1975, it would have been Russia. Since then it is the U.S.A. This is based on "known" flights.
has there been a space missions to mars
how mant astronauts have been to space
Nope. Children has never been in space.
Most likely nbsp is/should be a computer code for non-breaking space (just a space), but has been printed out by some mistake.
The United States and Russia have been the two countries that have done the most work in space exploration. They have made significant contributions to space research, sending numerous missions, satellites, and astronauts into space, and have played crucial roles in the development of the International Space Station.
As of September 2021, the latest space launch with astronauts was SpaceX's Crew-2 mission to the International Space Station on April 23, 2021. So, as of the most recent data available, it has been approximately 5 months since someone went into space.
