What the names of space lander in 1992?

In 1992, the notable space lander was the Mars Observer, which was intended to orbit Mars but unfortunately lost contact shortly before entering Mars' orbit. Another significant mission was the European Space Agency’s (ESA) Giotto spacecraft, which performed a flyby of Halley's Comet and provided valuable data about its composition. However, no landers successfully landed on a celestial body in 1992.
