Moon Exploration

An increasing number of space agencies consider Moon exploration as a part of national and international space programs. Exploration plans include a distributed network of facilities on and around the Moon; opportunities for “driving force” projects based on the International Space Station program experience; and, on the whole, formation of the “Earth – low lunar orbit – Moon surface” payload traffic flow. The payload needs analysis shows that the cutting-edge Moon exploration program requires high quality navigation services (precise estimation of coordinates and velocity in near-real time). The subject of this paper is the issues of creating a navigation service based on the experience of the Russian segment of ISS and using the existing near-Earth GNSS systems as a navigation infrastructure.

Small Scale Model

An attempt at improving the ventilation solution for the crew quarters aboard the International Space Station requires a thorough understanding of the flow dynamics in a microgravity environment. An experimental study is required in order to validate the numerical models. As part of this process, a small-scale model was proposed for a detailed study of the velocity field. PIV measurements in water offer high quality results and were chosen for the subject. Following certain similitude criteria, an equivalence can be found between the results of these measurements and the real ventilation scenario. This paper describes the development process of this small-scale model as well as its performance in the initial test runs. Details regarding the advantages and weaknesses of this first model are the core of the paper, with the intention of aiding researchers in their design of similar models. The conclusion presents future steps and proposed improvements to the model.

Abstract The extended meniscus and the intermolecular and capillary forces that govern its behavior and connection to change of phase heat transfer have been the subject of an increasing body of research over the past 50 years. We have been fortunate to be at the forefront of this effort starting from the development of a capillary feeder, in Earth's gravity, to stabilize film boiling to running a series of transparent heat pipe experiments aboard the International Space Station hoping to better understand the role of intermolecular forces in microgravity. The use of ellipsometry and interferometry to highlight the location and state of the vapor-liquid interface have been key to these studies and have helped to uncover many new, interesting, and sometimes unexpected, phenomena associated with fluid flow and change-of-phase heat transfer.

Do So

Be it harsh snowy mountains or dry hostile deserts, wherever there is space to expand into humans have done so boldly. With Earth mostly discovered and inhabited it is hardly surprising that many countries, organizations and space agencies are already making preparations to build permanent settlements and bases throughout the solar system starting with the Moon and Mars. The Moon our only satellite and the closest celestial body to the Earth is the next logical step in the ladder to becoming an interplanetary civilization. We have the technology to do so and NASA’s current estimates say it could be possible with a budget of 20 to 40 billion Dollars spread over the time of a decade. This budget is comparable to that of the International Space Station or a mere 1% of the United States Federal Budget in 2019. A small investment with an immeasurable payoff if done right. This is a step in the right direction towards becoming a type 2 civilization on the Kardashev scale, develop new technologies and discover new sources of energy.

Visual Instrumental Observations (VIOs) of the Earth’s surface is a very special activity for cosmonauts that include searching, finding, and monitoring the objects with the unaided eye and their registration using optical facilities expanding capabilities of an operator’s visual analyzer. In order to impart the correct practical skills in performing VIOs from the ISS to cosmonauts in the course their ground training it is necessary to visualize the image observed by the naked eye and/or in the camera view finder taking into account an optical zoom, mutual location of a cosmonaut, a camera, a window, and the station at a certain point in orbit. For these purposes, the special simulator which simulates an external visual environment as close as possible to the flight conditions has been developed, that is the VIOs simulator designated to train cosmonauts for performing tasks in the field of geophysical studies and monitoring of the Earth.

AbstractThe extreme ultraviolet (EUV) imager, EUVI-B, on board the International Space Station (ISS) under the International Space Station–ionosphere-mesosphere-atmosphere plasmasphere cameras (ISS-IMAP) mission was originally intended to observe EUV emissions at 83.4 nm scattered by $${\mathrm O}^+$$ O + ions. During the mission, EUVI-B occasionally detected evident EUV signals in the umbra of the Earth. However, the source of the signals has not been verified. To evaluate the effect of the 83.4 nm EUV, we conduct a Monte Carlo simulation which considers multiple scattering of the 83.4 nm EUV by $${\mathrm O}^+$$ O + ions. In addition, we modeled the contribution of the 91.1 nm emission, which is due to recombination of $${\mathrm O}^{+}$$ O + ions and electrons, because the 91.1 nm EUV might affect the measurement from EUVI-B due to the wavelength range covered. The results suggest that the effect of the 83.4 nm EUV is likely to be negligible while the 91.1 nm EUV explains the observations from EUVI-B morphologically and quantitatively. We therefore conclude that the EUV signals observed by EUVI-B in the umbra of the Earth can largely be attributed to 91.1 nm emission due to recombination. This conclusion would facilitate the use of the EUVI-B data for reconstructing the $${\mathrm O}^+$$ O + density.
