“…Current trends associated with the miniaturization of space technology contribute to the widespread use of small spacecraft in various fields of science, engineering and technology. The small spacecraft have proven themselves in remote sensing of the Earth from space (for example, «Aist -2D» [1,2]), scientific experiments in space (for example, Lomonosov [3]) and other areas due to the low cost and short term of the space project. The small spacecraft plan to use for the development of space technology in the near future.…”

Modeling the deformation of an elastic element of a small spacecraft in its plane during temperature shock

A basic mathematical model of the deformation of a large elastic element of a small spacecraft in its plane is constructed. Deformations are caused by a temperature shock after a small spacecraft leaves the Earth’s shadow on the solar portion of the orbit. The model is used to conduct a computational experiment with the aim of assessing perturbations acting on a small spacecraft due to temperature shock. The temperature distribution during thermal shock is described by a one-dimensional model of thermal conductivity. The classical theory of thin plates is used to determine the deformations. The results of the estimation of disturbing factors are obtained as a result of a computational experiment for a model small spacecraft. These results indicate the need to compensate for the impact of temperature shock for small technological spacecraft. The data obtained can be used in the design of small space-craft for technological purposes.

“…The BDRG instrument operated in two main observational modes: the monitor, or continuous observation, and event modes. The optical and γ-ray GRB light curves were recorded simultaneously, allowing detection of prompt GRB emission, as well as GRB precursors in the optical band [48]. The UFFO payload included the wide-field coded mask X-ray Burst Alert and Trigger Telescope (UBAT) and the optical/UV telescope.…”

Key Space and Ground Facilities in GRB Science

Gamma-ray bursts (GRBs) are short and intense flashes of γ-rays coming from deep space. GRBs were discovered more than a half century ago and now are observed across the whole electromagnetic spectrum from radio to very-high-energy gamma rays. They carry information about the powerful energy release during the final stage of stellar evolution, as well as properties of matter on the way to the observer. At present, space-based observatories detect on average approximately one GRB per day. In this review, we summarize key space and ground facilities that contribute to the GRB studies.
