Vanguard 1 is an American satellite that was the fourth artificial Earth-orbiting satellite to be successfully launched, following Sputnik 1, Sputnik 2, and Explorer 1. It was launched 17 March 1958. Vanguard 1 was the first satellite to have solar electric power. Although communications with the satellite were lost in 1964, it remains the oldest human-made object still in orbit, together with the upper stage of its launch vehicle.
TacSat-2 is the first in a series of U.S. military experimental technology and communication satellites.TacSat-2 (also known as JWS-D1 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.
The Space Test Program (STP) is the primary provider of spaceflight for the United States Department of Defense (DoD) space science and technology community. STP is managed by a group within the Advanced Systems and Development Directorate, a directorate of the Space and Missile Systems Center of the United States Space Force. STP provides spaceflight via the International Space Station (ISS), piggybacks, secondary payloads and dedicated launch services.
TacSat-1 was an experimental satellite built by the Naval Research Laboratory (NRL) on behalf of the United States Department of Defense (DoD) Office of Force Transformation (OFT). It was the planned payload of the sixth launch of the SpaceX Falcon 1. It was however never launched into space. The second satellite in the series, TacSat-2, launched before TacSat-1 and this led to the cancellation of TacSat-1's launch.
TacSat-3 is the second in a series of U.S. military experimental technology and communication satellites. It was assembled in an Air Force Research Laboratory (AFRL) Space Vehicles Directorate facility at Kirtland Air Force Base, New Mexico. The TacSat satellites are all designed to demonstrate the ability to provide real-time data collected from space to combatant commanders in the field.
The Advanced Research and Global Observation Satellite (ARGOS) was launched on 23 February 1999 carrying nine payloads for research and development missions by nine separate researchers. The mission terminated on 31 July 2003.
The Operationally Responsive Space Office is a joint initiative of several agencies within the United States Department of Defense (DoD). The "stand up" of the office took place 21 May 2007 at Kirtland Air Force Base. The first director of the ORS Office was Col. Kevin McLaughlin, who was also dual-hatted as commander of the Space Development and Test Wing located at Kirtland. The ORS Office focuses on providing quick-response tactical space-based capabilities to the warfighter utilizing smaller satellites, such as the Tactical Satellite Program and smaller launch vehicles.
TacSat-4 is the third in a series of U.S. military experimental technology and communication satellites. The United States Naval Research Laboratory (NRL) is the program manager. The Office of Naval Research (ONR) sponsored the development of the payload and funded the first year of operations. The Office of the Director of Defense Research and Engineering (DDR&E) funded the standardized spacecraft bus and the Operationally Responsive Space Office (ORS) funded the launch that will be performed by the Air Force's Space and Missile Systems Center (SMC).
The Micro-satellite Technology Experiment (MiTEx) is a microsatellite-based mission launched into geosynchronous orbit 21 June 2006 aboard a Delta II rocket. The USAF described the mission as a "technology demonstration" for the Defense Advanced Research Projects Agency (DARPA), the United States Air Force (USAF) and the United States Navy.
CP6, also known as CP6 CubeSat, CalPoly CP-6, PolySat-6 or PolySat CP6 is a single-unit CubeSat which was built and operated by the California Polytechnic State University (CalPoly). 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.
GeneSat-1 is a NASA fully automated, CubeSat spaceflight system that provides life support for bacteria E. Coli K-12. The system was launched into orbit on 16 December 2006, from Wallops Flight Facility. GeneSat-1 began to transmit data on its first pass over the mission's California ground station.
Nanoracks LLC is a private in-space services company which builds space hardware and in-space repurposing tools. The company also facilitates experiments and launches of CubeSats to Low Earth Orbit.
OA-4, previously known as Orbital-4, was the fourth successful flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its third flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-1) contract with NASA. With the Antares launch vehicle undergoing a redesign following its failure during the Orb-3 launch, OA-4 was launched by an Atlas V launch vehicle. Following three launch delays due to inclement weather beginning on 3 December 2015, OA-4 was launched at 21:44:57 UTC on 6 December 2015. With a liftoff weight of 7,492 kg (16,517 lb), OA-4 became the heaviest payload ever launched on an Atlas V. The spacecraft rendezvoused with and was berthed to the ISS on 9 December 2015. It was released on 19 February 2016 after 72 days at the International Space Station. Deorbit occurred on 20 February 2016 at approximately 16:00 UTC.
Vanguard TV-0, also called Vanguard Test Vehicle-Zero, was the first sub-orbital test flight of a Viking rocket as part of the Project Vanguard.
Vanguard TV-1, also called Vanguard Test Vehicle-One, was the second sub-orbital test flight of a Vanguard rocket as part of the Project Vanguard. Vanguard TV-1 followed the successful launch of Vanguard TV-0 a one-stage rocket launched in December 1956.
Vanguard TV-2, also called Vanguard Test Vehicle-Two, was the third suborbital test flight of a Vanguard rocket as part of Project Vanguard. Successful TV-2 followed the successful launch of Vanguard TV-0 a one-stage rocket launched in December 1956 and Vanguard TV-1 a two-stage rocket launched in May 1957.
RSat-P is a microsatellite built by the United States Naval Academy (USNA) in Annapolis, Maryland. The small spacecraft is a 3U CubeSat intended to demonstrate capabilities for minor in-orbit repair of a much larger, conventional spacecraft.
NG-14, previously known as OA-14, was the fifteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its fourteenth flight to the International Space Station under the Commercial Resupply Services (CRS-1) contract with NASA. The mission was launched on 3 October 2020, at 01:16:14 UTC.
Cygnus NG-16, previously known as Cygnus OA-16, was the sixteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its fifteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-2) contract with NASA. The mission was launched on 10 August 2021 at 22:01:05 UTC, for a (planned) 90-day mission at the ISS. This was the fifth launch of Cygnus under the CRS-2 contract.
SpaceX CRS-27, also known as SpX-27, was a Commercial Resupply Service mission to the International Space Station (ISS) launched on 15 March 2023. The mission was contracted by NASA and was flown by SpaceX using Cargo Dragon C209. This was the seventh flight for SpaceX under NASA's CRS Phase 2.
