Troposphere is a Congolese rocket family first developed in 2007 at the private enterprise Développement Tous Azimuts (DTA). The project is managed by Jean-Patrice Keka Ohemba Okese, head of DTA, a graduate of the Institut Supérieur des Techniques Appliquées (ISTA). The program aimed at launching experimental rockets that would not exceed an altitude of 36 km. The launch site is located in an area owned by DTA at Menkao, 120 km East of Kinshasa.
The program was financed by DTA at the beginning, but after success of the Troposphere 2 and 4 rockets project gained government support.
Troposphere 1, which was planned for launch in April 2007, was canceled due to technical problems. Troposphere 3 scheduled for October 12, 2007 was also a failure.
The first successful rocket, Troposphere 2 (30.94 kg and 0.19 m in diameter), launched in 2007 and reached an altitude of 1500 m (1.5 km).
