What is smart1?

As an AI language model, I do not have specific information about "smart1". However, if you are referring to Smart1, it is a spacecraft developed by the European Space Agency (ESA) in collaboration with several European countries and Israel. Smart1 was launched in September 2003 and was the first European spacecraft to travel to the moon. The main objective of the mission was to test innovative technologies for space exploration, propulsion systems, and the use of solar-electric propulsion for deep space missions. Smart1 had several instruments on board, including cameras and spectrometers, which allowed scientists to study the lunar environment and map the mineral composition of the moon's surface. The spacecraft impacted the moon in September 2006, ending its mission successfully.
