TEXUS 51/52

The project

 

The TEXUS project is a sounding rocket program with the primary aim to investigate the properties and behavior of materials, chemicals, and biological substances in a microgravity environment. The TEXUS program gives around six minutes of microgravity.
The TEXUS programme started in 1977 and is carried out at Esrange Space Center jointly by DLR, Airbus Defence&Space, OBH-System (former EADS Astrium and Kayser Threde) and SSC. SSC is responsible for the launch operations. The TEXUS campaigns are sometimes financed by ESA or jointly financed by DLR and ESA.

 

TEXUS 51/52

 

The rocket vehicle Skylark 7 was used very successfully for the first 25 years until the motor was no longer available. The Brazilian motor VSB-30 has been used for the TEXUS programme since 2005 and will be used to launch the TEXUS 50 and 51 payloads to around 270 km altitude.

The TEXUS 51 payload was scheduled to be launched from Esrange during the period April 2 – 25, 2013 in a double campaign with TEXUS 50. Due to technical problems, the TEXUS 51 campaign was canceled. TEXUS 51 will be launched in a double campaign with TEXUS 52 in April 2015.
