However, they are continuously gathering data and making new observations through:
* The Artemis program: This ongoing program aims to return humans to the moon and establish a sustainable presence there. While not a specific discovery, it's leading to a wealth of new information about the lunar surface and environment.
* The Lunar Reconnaissance Orbiter (LRO): This spacecraft continues to map and study the moon, providing valuable data on its geology, topography, and resources.
* Other missions: NASA is involved in various other missions studying the moon, including the Lunar Crater Observation and Sensing Satellite (LCROSS) and the Gravity Recovery and Interior Laboratory (GRAIL).

It's important to note that "discovery" is often relative. Many new observations are made constantly, but they may not be considered "major" discoveries until they are thoroughly analyzed and interpreted by scientists.
