TEXUS 50/51 RSS

Around six minutes of microgravity

The TEXUS programme started in 1977 and is carried out at Esrange Space Center jointly by DLR, EADS Astrium, Kayser Threde and SSC.

The project

The TEXUS project is a sounding rocket program with the primary aim to investigate the properties and behaviour 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, EADS Astrium, 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 50/51

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.
