The 'Ulysses' spacecraft flew by Jupiter 8 February 1992 .
The spacecraft Ulysses was launched on October 6, 1990. It was a joint mission by NASA and the European Space Agency (ESA) to study the Sun's poles and solar wind. Ulysses completed its mission by providing valuable data about solar activity and the heliosphere until its final contact in 2009.
None. Mercury was discovered before spacecraft were invented.

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.
The Ulysses spacecraft was a joint mission by NASA and the European Space Agency launched on October 6, 1990. It was designed to study the Sun's polar regions and solar wind, making it the first spacecraft to do so. Ulysses used a gravity assist from Jupiter to achieve its unique polar orbit, allowing it to observe solar activity over an extended period from 1994 to 2009. The spacecraft provided valuable data on the solar magnetic field, cosmic rays, and the heliosphere, significantly enhancing our understanding of solar influences on the solar system.
