What else can I help you with?
Who is the first person who jumped into earth orbit without a spacecraft?
Not yet so far..:-)because its not possible to a human to go onto a space without any spacecraft... but The first man who jumped in an earth's orbit with a spacecraft is "YURI GAGARIN"
What extraterrestial people invented the spacecraft?
There is no definitive evidence to suggest that any extraterrestrial people invented spacecraft. The development of spacecraft on Earth is attributed to human technology and ingenuity. The idea of extraterrestrial involvement in spacecraft technology remains a matter of speculation and not supported by concrete evidence.
Why aliens came to the Earth by spacecraft?
there isn't any proof of any alien spacecraft even exists but even if aliens exist they would have some sort of spacecraft to go to earth in because there isn't any other known way of getting living things from planet to planet.
What planet was the first to be visited by spacecraft?
The first planet to be visited by spacecraft was Venus. The Soviet spacecraft Venera 1 was the first to fly by Venus in 1961, followed by flybys and landings by subsequent missions from various countries.
What are the List of the names of any satellites or robots that have explored Neptune up close?
Voyager 2 is the only spacecraft to have gone near Neptune.
Has any spacecraft visited the planet earth?
Yes. Every spacecraft ever made by humans originated on Earth and most never went farther than an orbit around Earth. Many have returned to the surface.
Have any satellites explored earth up close?
Plenty. Just look Google Earth for the pictures of everything.
What are the human explorations on Saturn?
No human explorations have been conducted on Saturn. All observations and studies of Saturn have been done through the use of spacecraft, such as the Cassini mission, which provided valuable data and images of the planet and its moons. There are no current plans for sending humans to explore Saturn in the near future.
Why do people think launching spacecraft from the moon is a desirable alternative to launching them from earth?
Due to the lack of gravity, launching a spacecraft of any sort is a lot easier.
Did any man made spacecraft visited earth?
It's not clear what you mean by "visited", here. All man-made spacecraft ORIGINATED from Earth. Some of them later RETURNED to Earth as well, and quite a few of them were designed to STUDY Earth (for example, weather satellites).
How the moon has been studied and explored?
The moon has been studied and explored through various means, including telescopic observations from Earth, unmanned spacecraft missions from various space agencies (such as NASA and ESA), manned missions (Apollo missions), and sample return missions (Apollo, Luna, and Chang'e missions). These missions have helped us understand the moon's geology, composition, and history.
Why were spacecraft sent to the moon?
Spacecraft were sent to the moon to study the lunar surface, conduct experiments in a low-gravity environment, and further our understanding of the moon's geology and history. Additionally, missions like the Apollo program aimed to demonstrate human exploration beyond Earth's orbit.
