Skua sounding rocket

Skua is the designation of a British sounding rocket which was launched between 1959 and 1981 in four versions over 300 times. [1] [2] [3] [4] [5] [6] [7] The Skua was developed by Bristol Aerojet and RPE Wescott. [1]

Contents

It consisted of a starting stage made up of several Chick rockets (like the Petrel) that burned for 0.2 seconds. [1] They propelled the rocket 20 metres over the 5-metre-long launch tube. [1] [8] After that, the Bantam main stage ignited. The solid rocket motor of the main stage had an end-burning propellant grain and burned for 30 seconds. [9] The starting stage descended on parachutes and was re-filled and re-used. [10]

The fastest jet stream velocity ever measured (656 km/h or 408 mph) was recorded by instruments on board a Skua rocket above South Uist, Outer Hebrides, Scotland at an altitude of 47,000 m (154,200 ft), on 13 December 1967. [11]

Versions

There were four versions of the Skua rocket: [1] [2] [3] [4] [5]

A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits are diminished by the cost of recovery and refurbishment.

The Uchinoura Space Center is a space launch facility in the Japanese town of Kimotsuki, Kagoshima Prefecture. Before the establishment of the JAXA space agency in 2003, it was simply called the Kagoshima Space Center (鹿児島宇宙空間観測所) (KSC). All of Japan's scientific satellites were launched from Uchinoura prior to the M-V launch vehicles being decommissioned in 2006. It continues to be used for suborbital launches, stratospheric balloons and has also been used for the Epsilon orbital launch vehicle. Additionally, the center has antennas for communication with interplanetary space probes.

Because it is on the Gulf Stream, it also occasionally gets exotic visitors.

The Interarmy Special Vehicles Test Centre (CIEES) (French: Centre Interarmées d'Essais d'Engins Spéciaux) was France's first space launch and ballistic missile testing facility. Outside France, the facility is often referred to by the name of the nearest town, Hammaguir (also called Hammaguira). It was established on 24 April 1947, by ministerial decree as the Special Weapons Test Center (CEES, Centre d'essais d'engins spéciaux) for use by the French Army. In 1948, it was turned over to the French Air Force, who renamed it CIEES. Its remote location in the middle of the Saharan Desert and its relative closeness to the Equator (compared with Metropolitan France) made it an attractive launch site for missiles and orbital rockets.
