Yes, NASA's Messenger spacecraft was the first to orbit Mercury. The European Space Agency's BepiColombo mission, launched in 2018, is currently en route to Mercury for a joint investigation with the Japan Aerospace Exploration Agency.
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.
MESSENGER is on its way to Mercury and will arrive in 2011
No, NASA has not sent astronauts to Mercury. The extreme temperatures and proximity to the sun make it a challenging destination for a crewed mission. However, NASA has sent robotic spacecraft like MESSENGER to study Mercury from orbit.
No, there have not been any space missions that have visited Uranus. The Voyager 2 spacecraft is the only spacecraft to have passed by Uranus, conducting a flyby in 1986. There are currently no upcoming missions planned to visit Uranus.
No clouds, sorry. Mercury is so close to the Sun, and so small, that it is incapable of retaining any kind of atmosphere, and the first requirement to produce clouds is an atmosphere.NASA's Messenger spacecraft recently sent back the closest and most detailed images of Mercury yet.
No. Because of its proximity to the Sun, Mercury is one of the least-studied planets - because terrestrial observations are so difficult. Only two spacecraft have studied Mercury; the Mariner 10 and the more recent Messenger. No landers have been sent there.
Yes, there have been probes sent to Mercury. Messenger and Mariner 10.
No. But the United States did have a Mercury Space Program.
As of now, there are no manned space probes in space. All probes sent beyond Earth's orbit are unmanned and controlled remotely from Earth. Manned missions have been limited to spacecraft that carry astronauts, such as the International Space Station or missions to the Moon.
Yes, the only other spacecraft to land on Mercury besides Mariner 10 is NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft, which successfully orbited Mercury from 2011 to 2015. MESSENGER had a planned impact on Mercury's surface at the end of its mission.
Many have been sent, although only around a third of missions actually got there. However, the number that were sent is around 42, with several planned by various agencies for 2010-2011 and beyond.16 probes have gone to Mars.
