QZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation in inclined, elliptical geosynchronous orbits.
Geosynchronous Transfer OrbitNote: Name of payload is provisional. Fourth launch of an ultimately 5 reconnaissance satellites for the South Korean Defense Acquisition Program Administration (DAPA), with 1 synthetic aperture radar (SAR) satellite on this launch. They will be launched to low Earth orbit between 600 and 700 km by 2025, enabling South Korea’s military to observe the nuclear-armed neighbor’s key military facilities every two hours with 30-50 centimeters resolution imagery, according to a 2019 report produced by the Korea Institute of S&T Evaluation and Planning. The project is lead by the Korean Agency for Defense Development (ADD) and Korea Aerospace Research Institute (KARI), with input from Korea Aerospace Industries (KAI), Hanwha Systems and Thales Alenia Space.

Low Earth OrbitSTP-S30 is a complex mission that will deliver research experiments and technology demonstrations to orbit for the DoD and contribute to future space systems development. The projected primary payload, DISKSat, will demonstrate sustained very low earth orbit (VLEO) flight and test a unique, 1-meter diameter, disk-shaped satellite bus that is designed to increase on-orbit persistence.
Low Earth OrbitRAISE-4 (RApid Innovative payload demonstration Satellite-4) is a satellite for on-orbit demonstrations of 15 demonstration components and equipment selected by public solicitation. The satellite will be operated in response to requests from the demonstration theme proposers, and will provide experimental data of the demonstration devices and environmental data during the experiments. 10 of the demonstrations are re-flight of those planned for RAISE-3, which failed to reach orbit in October 2022.
Sun-Synchronous OrbitTrue Anomaly’s Jackal Autonomous Orbital Vehicle (AOV) will support U.S. Space Force Space Systems Command’s VICTUS HAZE Tactically Responsive Space (TacRS) mission with operations in orbit proximity with another spacecraft built by Rocket Lab National Security. The spacecraft, once completed, will remain on call until the U.S. Space Force provides the notice to launch. The Firefly team will then have 24 hours to transport the payload fairing to the pad, mate the fairing to the Alpha rocket, fuel the rocket, and launch within the first available window.
