NASA will be performing network maintenance on Thursday, November 14, 2024, between 5:15 PM EST and 7:15 PM EST (22:15 to 00:15 UTC). There will be two periods of about five minutes of disruption. During these peroids, the ILRS website will be unavailable during the outages. If you experience problems outside this window, contact support-cddis@nasa.gov.

Future Missions

Satellite Name Sponsor Exp.Life Time Purpose Launch Date
Approved by ILRS for Future SLR Tracking
e-kagaku-1 The e-kagaku Association of Global Science and Education, Japan Up to 1 yr Education of junior-high and high school students, fostering space engineers of next generation. Involving a wide range of age groups in project-based learning.

Establishing learning methods for satellite systems. Another objective is demonstrating SLR using mini-Mt. FUJI retroreflectors. Conducting orbit analysis by laser ranging, and publishing high-precision orbit information for the first time as a CubeSat.		 Early-Mid 2025
HTV-X JAXA, Japan 1 yr HTV-X is the new unmanned spacecraft as the successor to the "Kounotori" (HTV). The main mission of the HTV-X is transporting cargoes to the International Space Stations (ISS). After departure of the ISS, there is technical demonstration phases to verify three different missions in orbit. Mt.FUJI mission is one of the missions and it is related to the Satellite Laser Ranging (SLR). The goals of Mt.FUJI mission are:
(1) to verify JAXA developed SLR reflector (named, Mt.FUJI) in orbit,
(2) to evaluate the accuracy of SLR-based attitude estimation using true data (telemetry of HTV-X),
(3) to evaluate the accuracy of GPS receiver positioning by comparing with SLR data.
SLR will be used to verify JAXA developed SLR reflector by detecting return light. Then, SLR will be used to obtain sufficient data to perform orbit determination and SLR-based attitude estimation, to evaluate the accuracy of the GPS receiver on HTV-X and quantitatively evaluation of SLR-based attitude estimation by comparing true attitude data (HTV-X telemetry).		 2025
