Experiments simulating the non-destructive collection of cosmic dust are conducted at the laboratory of the Lehrstuhl fur Raumfahrttechnik (LRT) of the Technische Universitat Munchen (TUM). The electromagnetic accelerator setup is described, which is capable of obtaining an impact velocity between 10 and 400 m/s with particle masses up to 1 g. The evaluation method of the ratio of collected to impacting particles is given. Various metallic surface structures were tested with respect to their collection efficiency using different types of particles from 1 to 500 micrometers in size for simulation of cosmic dust. The simulation results are presented with emphasis on collection mechanisms. Particular influences on the collection mechanisms are discussed.

The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary mechanisms of our universe. The study of such events in the millimeter and submillimeter is, however, still in its infancy. Submillimeter observations probe a variety of materials, such as optically thick dust, which are hard to study in other wavelengths.

Small organic molecules are essential building blocks of our universe, from cosmic dust to planetary surfaces to life. Compared to their well-known gaseous and liquid forms that have been extensively studied, small organic molecules in the form of ice at low temperatures receive much less attention. Here, we show that supercooled small-molecule droplets can be drawn into highly uniform amorphous ice microfibers with lengths up to 5 cm and diameters down to 200 nm.

One of the most surprising and important findings of the first human landings on the Moon was the discovery of a very fine layer of lunar dust covering the entire surface of Moon along with the negative impacts of this dust on the well-being and operational effectiveness of the astronauts, their equipment, and instrumentation. The United States is now planning for human missions to Mars, a planet where dust can also be expected to be ubiquitous for many or most landing sites. For these missions, the design and operations of key hardware systems must take this dust into account, especially when related to crew health and safety.

The Artemis program and lunar gateway present an opportunity to advance NASA's presence away from Earth's orbit and back to the Moon. Astronauts will be faced with many dermatological challenges unique to the lunar environment, such as the surface material on the Moon. We used PubMed and Google Scholar to perform a literature review with articles related to the effects of lunar dust on skin collated and analyzed to assess the dermatological implications of these missions.

Most stars in today's Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies. Their formation is still an unsolved problem. Infrared/submillimetre-bright galaxies at high redshifts have long been suspected to be related to spheroid formation.
