Scout X-1A was an American sounding rocket which was flown in 1962. It was a five-stage derivative of the earlier Scout X-1, with an uprated first stage, and a NOTS-17 upper stage.

Sounding rocket Rocket carrying scientific instruments

A sounding rocket, sometimes called a research rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to carry instruments from 30 to 90 miles above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 25 mi (40 km) and the minimum for satellites is approximately 75 mi (121 km). Certain sounding rockets have an apogee between 620 and 930 miles, such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 600–1,000-pound (270–450 kg) payloads into the exoatmospheric region between 60 and 125 miles.

Scout X-1 American expendable launch system and sounding rocket used in the early 1960s

Scout X-1 was an American expendable launch system and sounding rocket which was flown seven times between August 1960 and October 1961. Four orbital and three suborbital launches were made, with four of the launches resulting in failures.

The Scout X-1A used an Algol 1C first stage, instead of the earlier Algol 1B used on the Scout X-1. The second, third and fourth stages were the same as those used on the Scout X-1; a Castor 1A, Antares 1A and Altair 1A respectively. The fifth stage was the NOTS-17 solid rocket motor, which had been developed by the Naval Ordnance Test Station.

The Scout X-1A was launched on its only flight at 05:07 GMT on 1 March 1962. It flew from Launch Area 3 of the Wallops Flight Facility. The flight carried an atmospheric re-entry experiment to an apogee of 214 kilometres (133 mi), and was successful. Following this, the Scout X-1A was replaced by the Scout X-2.

Wallops Flight Facility Launch Area 3

Launch Area 3 (LA-3) at the Wallops Flight Facility is a launch complex which was used, mostly by Scout rockets, between 1960 and 1985. Forty-one Scout launches occurred from the complex, making both orbital and suborbital. In addition, four Nike sounding rockets were launched from the complex in 1970.

Scout X-2 was an American expendable launch system and sounding rocket which was flown twice in 1962. It was a four-stage rocket, based on the earlier Scout X-1, uprated first and third stages. It was a member of the Scout family of rockets.

The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages.

2009 in spaceflight spaceflight-related events during 2009

Several significant events in spaceflight occurred in 2009, including Iran conducting its first indigenous orbital launch, the first Swiss satellite being launched and New Zealand launching its first sounding rocket. The H-IIB and Naro-1 rockets conducted maiden flights, whilst the Tsyklon-3, Falcon 1 and Ariane 5GS were retired from service. The permanent crew of the International Space Station increased from three to six in May, and in the last few months of the year, Japan's first resupply mission to the outpost, HTV-1, was conducted successfully.

NanoSail-D

NanoSail-D was a small satellite which was to have been used by NASA's Ames Research Center to study the deployment of a solar sail in space. It was a three-unit CubeSat measuring 30 by 10 by 10 centimetres, with a mass of 4 kilograms (8.8 lb). The satellite was lost shortly after launch due to a problem with the rocket carrying it; however, a replacement, NanoSail-D2, was launched in 2010 to complete its mission.

Vandenberg AFB Space Launch Complex 4

Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Air Force Base with two pads, both of which are used by SpaceX for Falcon 9 launch operations.

NOTS-EV-1 Pilot

The NOTS-EV-1 Pilot, also known as NOTSNIK was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS). Ten were launched during July and August 1958, all of which failed. It was the first air-launched rocket to be used for an orbital launch attempt; however, none was recorded as having reached orbit. Following the first and third orbital launch attempts, a tracking station in New Zealand reported receiving weak signals from the spacecraft; however, this was never confirmed, and the launches were not catalogued as having reached orbit. The Pilot rocket was part of Project Pilot.

Delta 2000

The Delta 2000 series was an American expendable launch system which was used to conduct forty-four orbital launches between 1974 and 1981. It was a member of the Delta family of rockets. Several variants existed, which were differentiated by a four digit numerical code.
The Delta 1000, 2000 and 3000 series used surplus NASA Apollo program rockets engines for its first and second stages.

NOTS-EV-2 Caleb

The NOTS-EV-2 Caleb, also known as NOTS-500, Hi-Hoe and SIP was an expendable launch system, which was later used as a sounding rocket and prototype anti-satellite weapon. It was developed by the United States Navy's Naval Ordnance Test Station (NOTS) as a follow-up to the NOTS-EV-1 Pilot, which had been abandoned following ten launches officially classified as failed missions. Two were launched in July and October 1960, before the cancellation of the project. Following cancellation, two leftover Calebs were used in the Satellite Interceptor Program (SIP), while three more were used as sounding rockets, under the designation Hi-Hoe. These derivatives flew until July 1962, when the Hi-Hoe made its final flight.

The RM-89 Blue Scout I was an American sounding rocket which was flown four times between January 1961 and April 1962. It was used for Two HETS test flights, and a flight to investigate atmospheric re-entry. It was a member of the Scout family of rockets.

Scout X-2M was an American expendable launch system which was flown three times between May 1962 and April 1963. It was a four-stage rocket, based on the earlier Scout X-2, but with an MG-18 upper stage instead of the Altair used on the X-2. It was a member of the Scout family of rockets.

The Scout X-2B was an American expendable launch system which was flown during 1963. It was a four-stage rocket, based on the earlier Scout X-2, but with an Altair 2A fourth stage in place of the Altair 1A used on the X-2. It was a member of the Scout family of rockets.

Progress-M1 Russian spacecraft which is used to resupply space stations

Progress-M1, also known as Progress 7K-TGM1, is a Russian spacecraft which is used to resupply space stations. It is a variant of the Progress spacecraft, derived from the Progress-M, but modified to carry more propellant for refuelling the space station instead of other cargoes such as water. A Progress M1 11F615A55 spacecraft could carry 1,700 kilograms (3,700 lb) of propellant, compared to the 850 kilograms (1,870 lb) that a Progress-M of the same generation could carry.

It was built in America by Westinghouse Electric, and had a mass at launch of 68 kilograms (150 lb). It was launched in 1964, and became the first satellite to be used for radio astronomy.

LauncherOne is a two stage orbital launch vehicle under development by Virgin Orbit since 2007. It is an air launch to orbit rocket, designed to launch "smallsat" payloads of 300 kilograms (660 lb) into Sun-synchronous orbit, following air launch from a carrier aircraft at high altitude. Launches are projected to begin in early 2019.
