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 the Esrange Space Center jointly by DLR and EADS Astrium. SSC is responsible for the launch operations. The TEXUS campaigns are financed by ESA, sometimes jointly with DLR.




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 49 payload to around 270 km altitude.
The TEXUS 49 payload carries three experiment modules on-board in which four different experiments are performed. This campaign is funded by DLR.
