Azur (also called GRS-A) was West Germany's first scientific satellite. Launched on 8 November 1969 it studied the Van Allen belts, solar particles, and aurorae.[2] [3]
The construction of the satellite was carried out by Ludwig Bölkow, one of the aeronautical pioneers of Germany, and with the participation of other German companies.[4]

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.
