El Arenosillo Test Centre (CEDEA) is the name of a rocket launch site for suborbital rockets managed by INTA, located in Moguer (Spain). It is located in the province of Huelva, Andalucía, in the southwest coast of Spain (37.1° N, 6.7° W). CEDEA is adjacent to the Center of Excellence for Unmanned Systems (CEUS). El Arenosillo is also the location of an autonomous astronomical observatory of the BOOTES network, with two domes and three telescopes.

Equipment

Among the main facilities that INTA has at CEDEA are (updated 2009): Complementing the above, the Center also has: In 2017 part of the equipment was damaged in a wildfire. In the years 2018 and 2019 INTA has dedicated part of its budget to replace damaged equipment.

Launch history

The first launch of a rocket from El Arenosillo took place 15 October 1966. Up to 1994 a total of 557 rockets were launched from this base, mainly of the Skua type for atmospheric soundings and in collaboration with other countries. Other rockets launched included Nike Cajun, Nike Apache, Centaure, Black Brant, Skylark, Petrel, Super Loki, INTA-255, INTA-300 and INTA-300B. All rockets for atmospheric soundings in Spain are launched from El Arenosillo. In 2015 Delft Aerospace Rocket Engineering broke the European altitude record for amateur rocketry by launching the Stratos II+ rocket to 21.5 km altitude from El Arenosillo. On 1 March 2017, Zero 2 Infinity tested its first rocket, a Bloostar prototype, in El Arenosillo. A balloon took Bloostar to 25 km. At 25 km the ignition of the rocket took place. The** goals of the mission were: (i) validation of the telemetry systems in Space conditions, (ii) controlled ignition, (iii) stabilization of the rocket, (iv) monitoring of the launch sequence, (v) parachute deployment, and finally, (vi) sea **recovery. All these goals were achieved in full. In 2023 PLD Space launched its first rocket Miura 1 from El Arenosillo. Only some launches are listed here. For information on individual rockets, see the List of rockets launched from El Arenosillo.
