NASA shares information from US satellites while China tells America about latitude, longitude, and landing time "on time," he said.
The hope is that NASA's Lunar Reconnaissance Orbiter (LRO) can observe the historic landing of Chinese landers on January 3.
NASA provided the planned LRO orbit path to China, but it turned out that the spacecraft was not in the right place at the right time.
"For a number of reasons, NASA cannot make the orbit phase of the LRO in its optimal location during landings, but NASA is still interested in possibly detecting the feathers after landing," the agency said in a statement.
"The science gathered about how moon dust is released upward during the landing of spacecraft can inform future missions and how they arrived on the surface of the moon."
This research is important for NASA's ambition to return to the Moon, with the mission scheduled for early next year.
The US campaign to return to the Moon, the first in more than 40 years, has been put forward by President Donald Trump, who has encouraged commercial and international funding to replace federal for international businesses.
