European eXPErimental Re-entry Test-bed (EXPERT) is a European Space Agency aerothermodynamics research programme. It was planned that vehicle will be launched on a Russian Volna launch vehicle and will provide knowledge and experience in the design and development of re-entry vehicles.[1] As of 2012, one element in a European Space Agency push to develop vehicles capable of re-entry has been pushed back until at least 2013 as the agency seeks a launch alternative to the Russian submarine-launched Volna rocket which was withdrawn.[2] One of its main goals was to test materials for ESA's Intermediate eXperimental Vehicle (IXV), an unmanned, delta-winged plane launched in 2015 aboard ESA's new Vega small-satellite launcher.[3] Currently EXPERT remains in storage conditions in Turin.[4]
EXPERT Mission objectives
[edit]According to an ESA-ESTEC paper,[5] the EXPERT program has the following goals:
- Enable in-flight data gathering of selected aerothermodynamic phenomena with high accuracy and reliability
- Allow the validation of numerical modeling tools (CFD) and of methodologies for ground-to-flight data extrapolation
- Qualify in-flight classical and advanced measurement techniques
- Conduct extensive post-flight analyses based on in-flight data, pre-flight numerical databases, preflight ground testing activities.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
