Space Technology 6

Last updated

Space Technology 6 (ST-6) is part of the NASA New Millennium Program. ST-6 is a subsystem technology demonstration that consisted of 2 separate projects, the Autonomous Sciencecraft Experiment on board the Earth Observing 1 satellite and the Inertial Stellar Compass (ISC) experiment aboard TacSat-2.

NASA space-related agency of the United States government

The National Aeronautics and Space Administration is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research.

New Millennium Program (NMP) was a NASA project with focus on engineering validation of new technologies for space applications. Funding for the program was eliminated from the FY2009 budget by the 110th United States Congress, effectively leading to its cancellation.

TacSat-2

TacSat-2 was an experimental satellite built by the USAF's Air Force Research Laboratory with an operational life expected to be not more than one year as part of the 'Advanced Concept Technology Demonstration' program.

Overview

The Autonomous Sciencecraft Experiment (ASE) is a software experiment that has been operating on board the Earth Observing-1 mission since 2003. The ASE software uses onboard continuous planning, robust task and goal-based execution, and onboard machine learning and pattern recognition to radically increase science return by enabling intelligent downlink selection and autonomous retargeting. This software demonstrates the potential for space missions to use onboard decision-making to detect, analyze, and respond to science events, and to downlink only the highest value science data.

The Inertial Stellar Compass (ISC) enables a spacecraft to continuously determine its attitude or the direction in which it is pointing. It also enables a spacecraft to recover its orientation (direction and pointing) after a temporary malfunction or power loss. This is done by combining a miniaturized star camera and a gyro system. Although this is not a new concept, the small size and low power consumption are revolutionary and an important feature for the new, smaller spacecraft and satellites of the future. It was flown aboard the TacSat-2 spacecraft in 2006.

Inertial Stellar Compass (ISC) is an instrument concept for an advanced navigation system designed to allow spacecraft of the future to operate more autonomously.

Raiko is a Japanese satellite which was built and operated by Tohoku and Wakayama Universities. A two-unit CubeSat, Raiko was deployed from the International Space Station on October 4, 2012, having been launched in July.

TacSat-1

TacSat-1 was an experimental satellite built by the Naval Research Laboratory on behalf of the United States Department of Defense (DOD) Office of Force Transformation (OFT). The second satellite in the series, TacSat-2, has already been launched. It was the planned payload of the sixth launch of the SpaceX Falcon 1.

MightySat-2.1, also known as P99-1 or Sindri was a small spacecraft developed by the Air Force Research Laboratory to test advanced technologies in imaging, communications, and spacecraft bus components in space.

FASTRAC

Formation Autonomy Spacecraft with Thrust, Relnav, Attitude and Crosslink is a pair of nanosatellites developed and built by students at The University of Texas at Austin. The project is part of a program sponsored by the Air Force Research Laboratory (AFRL), whose goal is to lead the development of affordable space technology. The FASTRAC mission will specifically investigate technologies that facilitate the operation of multiple satellites in formation. These enabling technologies include relative navigation, cross-link communications, attitude determination, and thrust. Due to the high cost of lifting mass into orbit, there is a strong initiative to miniaturize the overall weight of spacecraft. The utilization of formations of satellites, in place of large single satellites, reduces the risk of single point failure and allows for the use of low-cost hardware.

Earth Observing-1

Earth Observing-1 (EO-1) is a decommissioned NASA Earth observation satellite created to develop and validate a number of instrument and spacecraft bus breakthrough technologies. It was intended to enable the development of future Earth imaging observatories that will have a significant increase in performance while also having reduced cost and mass. The spacecraft was part of the New Millennium Program. It was the first satellite to map active lava flows from space; the first to measure a facility's methane leak from space; and the first to track re-growth in a partially logged Amazon forest from space. EO-1 captured scenes such as the ash after the World Trade Center attacks, the flooding in New Orleans after Hurricane Katrina, volcanic eruptions and a large methane leak in southern California.

PharmaSat

PharmaSat was a nanosatellite developed by NASA Ames Research Center which measured the influence of microgravity upon yeast resistance to an antifungal agent. As a follow on to the GeneSat-1 mission, the Ames Small Spacecraft Division conducted the PharmaSat mission in collaboration with industry and local universities.

AeroCube 3 is a single-unit CubeSat which was built and is being operated by The Aerospace Corporation. It is the third AeroCube satellite, following on from AeroCube 1, which was lost in a launch failure in 2006, and AeroCube 2 which was successfully launched in 2007 but failed immediately after launch. Compared to its predecessors it contains several improvements in its infrastructure, including a redesigned power system, replacing the older system which was responsible for the loss of AeroCube 2. Its development was funded by the United States Air Force Space and Missile Systems Center.

CP6, also known as PolySat-6, PolySat CP-6 or CalPoly 6 is a single-unit CubeSat which was built and operated by the California Polytechnic State University. It was primarily intended to perform a technology demonstration mission. The main experiment consisted of sensors to determine the spacecraft's attitude. Cameras on the satellite will be used to verify the data returned by the attitude sensors. Originally built as a backup to CP3, which was launched in April 2007, CP6 was modified after it was decided that it would no longer be needed for that role.
