CelesTrak is a
501(c)(3) non-profit
and we need your help. Our mission remains focused on making data
and other resources freely available to the space community to facilitate
understanding of our orbital environment and how to use it safely and
responsibly.
Please consider making a small monthly donation now to help
us hire staff to contine CelesTrak's legacy and vision.

URGENT: We ran out of 5-digit catalog numbers on 2026-07-11.
The official USSF SATCAT is now at 100982.
All newly cataloged objects have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format.
Please be sure to use one of CelesTrak's other formats which remove the 5-digit catalog number limitation (and finally fix the Y2K problem) and to adhere to our usage policy when retrieving any CelesTrak data.
