![]() The campaign is assembling a defined set of rock samples from around the world that are comparable to rock samples from the Red Planet that are scheduled to be brought to Earth in 2033.ĭue to its unique geology, Rum off the west coast of Scotland has been selected as the only UK site for sampling, as some of its igneous rocks have a very similar mineral and chemical content to those that have been collected by NASA’s Perseverance Rover during its exploration of an ancient crater on Mars. Newland, D.E.: Random vibration.Ancient rocks from the Isle of Rum are playing an important role in an international space mission to discover more about Mars.Ī group of scientists, including a space scientist from University of Leicester and Space Park Leicester, have this week been collecting samples of rock from the NatureScot National Nature Reserve (NNR) as part of the NASA and European Space Agency (ESA)’s Mars Sample Return Campaign.

It indicates that lightweight design in this paper is feasible. The structure has enough strength, stiffness, and stability. The results of simulations show that the structure is reliable with a large safety margin. Structural analysis, which is based on the finite element method, is conducted under different kinds of load cases. What’s more, some region of support plate has stiffeners and ribs for high reliability. The support plate adopts the symmetrical design, and most areas of it have been hollowed out with unique method for weight loss. The supports are three bipod supports, which have some flexible links. ![]() The purpose is to make the primary mirror lighter. Furthermore, the back of mirror has a particular curvy surface. Special hexagonal holes are dug on the back of primary mirror. These three parts are primary mirror, supports, and support plate. The primary mirror component has three parts. The paper makes a lightweight design for a kind of primary mirror component. ![]() The primary mirror component is a main part in the space telescope system, the deadweight of it affects the weight of the whole telescope. With the improvement of space optics technology, lightweight design is becoming more and more important in the process of designing a space telescope.
