Particle flows in a dc discharge in laboratory and microgravity conditions [PDF]
Physical Review E 87, 063109 (2013), 2013 We describe a series of experiments on dust particles flows in a positive column of a horizontal dc discharge operating in laboratory and microgravity conditions. The main observation is that the particle flow velocities in laboratory experiments are systematically higher than in microgravity experiments, for otherwise identical discharge conditions ...

Probing supermassive black hole binaries with orbital resonances of laser-ranged satellites
European Physical Journal C: Particles and Fields, 2023 Coalescing supermassive black hole binaries (SMBHBs) are the primary source candidates for low frequency gravitational wave (GW) detections, which could bring us deep insights into galaxy evolutions over cosmic time and violent processes of spacetime ...

RAMP: Reaction-Aware Motion Planning of Multi-Legged Robots for Locomotion in Microgravity [PDF]
arXiv, 2023 Robotic mobility in microgravity is necessary to expand human utilization and exploration of outer space. Bio-inspired multi-legged robots are a possible solution for safe and precise locomotion. However, a dynamic motion of a robot in microgravity can lead to failures due to gripper detachment caused by excessive motion reactions.

Engineering and Scientific International Journal, 2020 Variations in telomeres, and especially their shortening, is a well-known process that marks the rhythm of life in all living things, but the reason behind telomere lengthening in some cases is not so well understood. We only know that it isdirectly related to the activation of an enzyme called telomerase.

Gene expression profiling in slow-Type calf soleus muscle of 30 days space-flown mice [PDF]
, 2017 Microgravity exposure as well as chronic disuse are two main causes of skeletal muscle atrophy in animals and humans. The antigravity calf soleus is a reference postural muscle to investigate the mechanism of disuse-induced maladaptation and plasticity ...

Evaporative cooling from an optical dipole trap in microgravity [PDF]
Phys. Rev. A 101, 013634 (2020), 2019 In recent years, cold atoms could prove their scientific impact not only on ground but in microgravity environments such as the drop tower in Bremen, sounding rockets and parabolic flights. We investigate the preparation of cold atoms in an optical dipole trap, with an emphasis on evaporative cooling under microgravity. Up to $ 1\times10^{6} $ rubidium-

The economics of microgravity research [PDF]
npj Microgravity, 2015 In this introduction to the economics of microgravity research, DiFrancesco and Olson explore the existing landscape and begin to define the requirements for a robust, well-funded microgravity research environment. This work chronicles the history, the opportunities, and how the decisions made today will shape the future.
