Institute for Unmanned Space Experiment Free Flyer

The Institute for Unmanned Space Experiment Free Flyer (USEF) (財団法人無人宇宙実験システム研究開発機構) was a Japanese space agency, which was founded by the Ichiro Taniguchi.

In 2012, USEF merged two other organizations—Japan Resources Observation System Organization (JAROS)—to form a new organization Japan Space Systems (J-spacesystems).

Goal

The aim of USEF is technology development, especially the testing of commercial off-the-shelf parts (COTS), robotics, material sciences and technology for optical earth observations.

Launch Vehicle

Unlike the JAXA organisation, USEF doesn't have its own launch vehicle. Instead, it has used either the H-IIA, the M-3S, or Russian rockets, so far. However in 2008, METI mentioned the possibility of USEF developing an air-launched vehicle for small payloads.[1]

Missions

Express

The Express is a 745 kg (1,642 lb) satellite for microgravity experiments and testing of re-entry technologies. The project was done in cooperation with ISAS (now JAXA) and DLR of Germany. On January 15, 1995, it was launched on the M-3S. However, due to a problem with the rocket, the orbit was much lower than planned. The re-entry capsule was found later in Ghana.[2]

Servis 1

The SERVIS-1 is an 840 kg (1,851 lb) technology test mission with COTS parts. It was launched on October 30, 2001 with the Russian Rockot launch vehicle. the mission duration was two years.[3]

USERS

USERS was launched on the H-IIA on September 10, 2002. The aim of the mission was microgravity experiments to perform the Super-Conductor Material Processing Experiment and also testing of satellite bus technologies. For the first part of the mission, USERS carried a return capsule. It was retrieved successfully on May 29, 2003. The mission of the main orbiter ended during re-entry in 2007.[4]

Servis 2

SERVIS-2 was a 900 kg (1,984 lb) technology test mission with COTS parts. It will continue the experiments done with the first SERVIS satellite. It was launched on June 2, 2010, 01:59 UTC, with the Russian Rockot launch vehicle.[5][6][7]

Asnaro 1

Asnaro-1, the first of "Advanced Satellite with New system Architecture Observation" series, is a 450 kg (992 lb) earth observation satellite. The expected resolution is less than 0.5 meter (1.6 ft) from an SSO orbit. The satellite was launched on 2014 Nov 6 by a Dnepr rocket from Yasniy, Russia.[8][9]

Planned Missions

Servis 3

Test of COTS parts. Follow-up mission to Servis 1 and 2. Launch is planned for 2013.[10]

Asnaro 2

Asnaro 2 is small x-band radar satellite for earth observation. Launch is planned for 2013.[11]

Other technology projects

USEF developed the robotic arm of the ETS-VII project to test docking technology in the 1990s.
