The Ansari X Prize was a space competition in which the X Prize Foundation offered a US$10,000,000 prize for the first non-government organization to launch a reusable crewed spacecraft into space twice within two weeks. It was modeled after early 20th-century aviation prizes, and aimed to spur development of low-cost spaceflight.
A spaceplane is an aerospace vehicle that can fly/glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in the vacuum of space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft, occupying an intermediate space between the two. Orbital spaceplanes are more like spacecraft, while sub-orbital spaceplanes are more like fixed-wing aircraft. All spaceplanes to date have been rocket-powered but then landed as unpowered gliders.
The Falcon 1 was an expendable launch system privately developed and manufactured by SpaceX during 2006–2009. On 28 September 2008, Falcon 1 became the first privately-developed liquid-fuel launch vehicle to go into orbit around the Earth.
SpaceDev, a part of the "Space Systems Business" of Sierra Nevada Corporation, is prominent for its spaceflight and microsatellite work. It designed and built components for the hybrid rocket motors for Paul Allen's Tier One suborbital SpaceShipOne space program operated by Scaled Composites. It is also developing micro- and nano-satellites, a small expendable launch vehicle, the SpaceDev Streaker, and has designed a piloted suborbital and orbital spaceship of its own, the SpaceDev Dream Chaser, in collaboration with NASA.
Air launching is the practice of releasing a rocket, missile, parasite aircraft or other aircraft payload from a mother ship or launch aircraft. The payload craft or missile is often tucked under the wing of the larger mother ship and then "dropped" while in flight. It may also be stored within a bomb bay, beneath the main fuselage or even on the back of the carrier aircraft, as in the case of the D-21 drone. Air launching provides several advantages over ground launching, giving the smaller craft an altitude and range boost, while saving it the weight of the fuel and equipment needed to take off on its own.
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under 500 kg (1,100 lb). While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system.
Interorbital Systems Corporation (IOS) is an American aerospace manufacturer active in Mojave, California. It was founded in 1996 by Roderick and Randa Milliron, who also co-founded Trans-Lunar Research, a non-profit organization.. They aim to develop a low-cost launch vehicle for commercial purposes, by using non-aerospace components whenever possible to keep the cost down.
Micro-Space was an aerospace corporation based in Denver, Colorado, founded in February 1977 by Richard P. Speck under the name Spectron Instrument Corporation. The corporation changed its name to "Micro-Space, Inc." in 1998. It was dissolved in 2011, following the death of the founder.
RocketShip Tours is an American space tourism company founded in 2008 by travel industry entrepreneur Jules Klar and which planned to provide sub-orbital human spaceflights to the paying public, in partnership with rocketplane developer XCOR Aerospace. Klar created RocketShip Tours to act as General Sales Agent for XCOR Aerospace.
The Falcon Heavy is a partially reusable heavy-lift launch vehicle designed and manufactured by SpaceX. It is derived from the Falcon 9 vehicle and consists of a strengthened Falcon 9 first stage as the center core with two additional Falcon 9-like first stages as strap-on boosters. The Falcon Heavy has the highest payload capacity of any currently operational launch vehicle, the second-highest capacity of any rocket ever to reach orbit, trailing the Saturn V, and the third-highest capacity of any orbital-class rocket ever launched successfully.
A secondary payload, also known as rideshare, is a smaller-sized payload transported to orbit on a launch vehicle that is mostly paid for—and with the date and time of launch and the orbital trajectory determined—by the entity that contracts and pays for the primary launch. As a result, the secondary payload typically obtains a substantially reduced price for transportation services to orbit, by accepting a trade off of the loss of control once the contract is signed and the payload is delivered to the launch vehicle supplier for integration to the launch vehicle. These tradeoffs typically include having little or no control over the launch date/time, the final orbital parameters, or the ability to halt the launch and remove the payload should a payload failure occur during ground processing prior to launch, as the primary payload typically purchases all of these launch property rights via contract with the launch services provider.
SpaceX CRS-8, also known as SpX-8, was a Commercial Resupply Service mission to the International Space Station (ISS) which was launched on April 8, 2016, at 20:43 UTC. It was the 23rd flight of a Falcon 9 rocket, the tenth flight of a Dragon cargo spacecraft and the eighth operational mission contracted to SpaceX by NASA under the Commercial Resupply Services program. The capsule carried over 3,100 kilograms (6,800 lb) of cargo to the ISS including the Bigelow Expandable Activity Module (BEAM), a prototype inflatable space habitat delivered in the vehicle's trunk, which will be attached to the station for two years of in-orbit viability tests.
Cygnus CRS Orb-3, also known as Orbital Sciences CRS Flight 3 or Orbital 3, was an attempted flight of Cygnus, an automated cargo spacecraft developed by United States-based company Orbital Sciences, on 28 October 2014. The mission was intended to launch at 6:22 PM that evening. This flight, which would have been its fourth to the International Space Station and the fifth of an Antares launch vehicle, resulted in the Antares rocket exploding seconds after liftoff.
SpaceX CRS-6, also known as SpX-6, was a Commercial Resupply Service mission to the International Space Station, contracted to NASA. It was the eighth flight for SpaceX's uncrewed Dragon cargo spacecraft and the sixth SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. It was docked to the International Space Station from 17 April to 21 May 2015.
Electron is a two-stage orbital expendable launch vehicle developed by the American aerospace company Rocket Lab to service the commercial small satellite launch segment. Its Rutherford engines, manufactured in California, are the first electric-pump-fed engine to power an orbital rocket.
Bristol Spaceplanes (BSP) is a British aerospace company based in Bristol, England, who have designed a number of spaceplanes with sub-orbital and orbital capabilities. The company's stated goal is "to realise low-cost access to space", primarily through reusable launch vehicles, claiming the cost of human space travel has the potential to be reduced by a factor of 1,000.
Cygnus CRS OA-9E, also known as Orbital ATK OA-9E and Northrop Grumman OA-9E, was the tenth flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its ninth flight to the International Space Station under the Commercial Resupply Services contract with NASA. The mission launched on May 21st, 2018 at 4:44 AM. Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital's industrial partner Thales Alenia Space.
