Calathus is a proposed student-designed Ceres sample-return mission, that would consist of an orbiter and a lander with an ascent module. The orbiter would be equipped with a camera, a thermal imager, and a radar; the lander will have a sampling arm, a camera, and a gas chromatograph mass spectrometer. Mission objective is to return maximum 40 grams (1.4 oz) of Ceresian soil.[1] The mission was designed and proposed in 2018 with support of ESA.[2]
Spacecraft should take samples from Occator Crater,[2] that was studied and photographed by NASA's Dawn. The objectives are:[2]
- to understand whether Ceres contains the ingredients for life
- to understand where Ceres was formed
- to understand whether asteroids like Ceres were responsible for delivering water and organics to Earth

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.
