Sirius FM-3, also known as Radiosat 3, was an American communications satellite which was operated by Sirius XM Radio, previously Sirius Satellite Radio. It was constructed by Space Systems Loral and was based on the LS-1300 satellite bus. Launch occurred on 30 November 2000, at 19:59 GMT. The launch was contracted by International Launch Services, and used a Proton-K/DM3 carrier rocket flying from Site 81/23 at the Baikonur Cosmodrome.
It was operating in a tundra orbit, from where it provided satellite radio communications services to North America. It had an expected operational lifetime of 15 years.
In 2016, the satellite was decommissioned and moved into a disposal orbit.[1]

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.
