The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command.
FalconSAT-2 was a satellite built by students of the United States Air Force Academy as part of the FalconSAT program. It was intended to have been placed into low Earth orbit to study the effects of plasma on communications with spacecraft, however it failed to reach orbit due to a malfunction of its carrier rocket.
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.
COSMO-SkyMed is an Earth-observation satellite space-based radar system funded by the Italian Ministry of Research and Ministry of Defence and conducted by the Italian Space Agency (ASI), intended for both military and civilian use. The prime contractor for the spacecraft was Thales Alenia Space. COSMO SkyMed is a constellation of four dual use Intelligence, surveillance, target acquisition, and reconnaissance (ISR) Earth observation satellites with a synthetic-aperture radar (SAR) as main payload, the result of the intuition of Giorgio Perrotta in the early nineties. The synthetic-aperture radar was developed starting in the late nineties with the SAR 2000 program funded by ASI.
Minotaur IV, also known as Peacekeeper SLV and OSP-2 PK is an active expendable launch system derived from the LGM-118 Peacekeeper ICBM. It is operated by Northrop Grumman Innovation Systems, and made its maiden flight on 22 April 2010, carrying the HTV-2a Hypersonic Test Vehicle. The first orbital launch occurred on 26 September 2010 with the SBSS satellite for the United States Air Force.
Orbcomm is a family of low Earth orbit communications satellites, operated by the United States satellite communications company Orbcomm. As of July 2014, 51 such satellites have orbited Earth, with 50 still continuing to do so.
Pegasus 1 or I, known before launch as Pegasus A, was an American satellite which was launched in 1965 to study micrometeoroid impacts in low Earth orbit. It was the first of three Pegasus satellites to be launched. The Pegasus spacecraft were manufactured by Fairchild Hiller, and operated by NASA.
Hermes was an American satellite which was to have been operated by the Colorado Space Grant Consortium. Intended to perform technology demonstration experiments in low Earth orbit, it was lost during launch in March 2011 when the rocket that was carrying it failed to achieve orbit.
USA-221, also known as FalconSat-5, is an American military minisatellite, which was launched in 2010. The fifth FalconSat spacecraft to be launched, it carries four technology development and ionospheric research experiments. The satellite was constructed and is operated by the United States Air Force Academy.
This article documents notable spaceflight events during the year 2018. For the first time since 1990, more than 100 orbital launches were performed globally.
PhoneSat is an ongoing NASA project of building nanosatellites using unmodified consumer-grade off-the-shelf smartphones and Arduino platform and launching them into Low Earth Orbit. This project is part of NASA's Small Spacecraft Technology Program and was started in 2009 at NASA Ames Research Center.
Space Tethered Autonomous Robotic Satellite II or STARS-II, was a nanosatellite built by Japan's Kagawa University to test an electrodynamic tether in low Earth orbit, a follow-on to the STARS mission.
Capella Space is an American space company. It is developing space-based radar Earth observation satellites equipped with synthetic-aperture radar that can penetrate clouds and work at night. The company is based in San Francisco, California. It was founded by Payam Banazadeh, a former engineer at Jet Propulsion Laboratory of NASA, and William Walter Woods.
ICEYE Ltd. is a Finnish microsatellite manufacturer. ICEYE was founded in 2014 as a spin-off of Aalto University's University Radio Technology Department, and is based in Espoo.
Landmapper is a remote sensing satellite constellation built and operated by Astro Digital. It consists of two separate satellite designs: Landmapper-BC and Landmapper-HD. These satellites will be launched into Sun synchronous orbits varying in altitude between 625 km and 475 km. Both satellites are designed to CubeSat standards: 6U XL for Landmapper-BC, and 16U for Landmapper-HD. They will be contained in deployers designed by Innovative Solutions in Launch of the Netherlands and ECM Launch Services of Germany. These deployers are to be included on board a variety of launch vehicles, including the SpaceX Falcon 9, Rocket Lab Electron, Glavkosmos Soyuz, Antrix PSLV, and European Space Agency Vega.
Orbiting Vehicle 1-1, was the first satellite in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-1 was an American Earth science research satellite designed to measure radiation, micrometeoroid density, and magnetic fields in orbit. Launched 21 January 1965, the mission resulted in failure when, after a successful launch of its Atlas booster, OV1-1's onboard Altair motor failed to fire.
USA-299, also referred to as USSF-7 and Orbital Test Vehicle 6 (OTV-6), is the third flight of the first Boeing X-37B, an American unmanned vertical-takeoff, horizontal-landing spaceplane. It was launched to low Earth orbit aboard an Atlas V launch vehicle from SLC-41 on 17 May 2020. Its mission designation is part of the USA series.
Orbiting Vehicle 1-8, launched 14 July 1966, was the seventh satellite launched in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-8 was designed to test the passive communications utility of an aluminum grid sphere versus a balloon satellite.
SatRev S.A. is a Polish company established in 2016, that specialises in building small, lightweight, nanosatellites. The company was listed in the NASA's "State of the Art Small Spacecraft Technology" report as one of 12 in the world.
