Living Organisms

Among the phenomena attributable to the Moon’s actions on living organisms, one of them seems to be related to analytical fluid mechanics: along the route of the International Space Station around the Earth, experiments on plants have revealed leaf oscillations. A parametric resonance due to a short period of microgravitational forces could explain these oscillations. Indeed, Rayleigh-Taylor’s instabilities occurring at the interfaces between liquid-water and its vapor verify a second-order Mathieu differential equation. This is the case of interfaces existing in the xylem channels of plant stems filled with sap and air-vapor. The magnitude of the instabilities depends on the distances between the Moon, the Sun, and the Earth. They are analogous, but less spectacular, to those that occur during ocean tides.

Technical Details

A new era of spaceflight dawned following the conclusion of the United States and Russian space race. This new era has been marked by the design, assembly, and operation of one of the greatest engineering feats mankind has accomplished, the International Space Station (ISS). The ISS is comprised of hundreds of thousands of kilograms of material built on the ground and transported to space for assembly. It houses an artificial atmosphere to sustain life in outer space and has been continually inhabited for over 15 years. This chapter describes the technical complexity of the ISS, the background of how it was assembled, its major systems, details of crew life onboard, commercial usage of the resource, and examples of mishaps that have occurred during the ISS's operation. The technical details of the ISS provide a glimpse into what future space stations that might orbit the Moon and Mars will resemble.

Subject Space stations. Significance As Washington returns its sights to the moon, it is reforming its policies regarding the International Space Station (ISS) with a view to jump-starting a 'low-earth orbit economy' in which private firms offer services to corporate clients, foreign governments and wealthy individuals. Impacts China's space station, due for completion in 2022, could draw third-country projects away from commercial US space stations. Governments are more promising clients for commercial crewed spaceflight than 'space tourists' are. Commercial stations and passenger spacecraft could make human spaceflight accessible to allied states. Spaceflight will remain politicised.

Ultraviolet Emissions

<p>Mini-EUSO is a telescope that observes the Earth from the International Space Station by recording ultraviolet emissions (290 ÷ 430 nm) of cosmic, atmospheric and terrestrial origin with a field of view of 44◦, a spatial resolution of 6.3 km and a temporal resolution of 2.5 mus.</p><p>The instrument is based on an optical system composed of two Fresnel lenses and a focal surface composed of 36 multi-anode photomultiplier tubes, 64 channels each, for a total of 2304 channels with single photon counting sensitivity.</p><p>Mini-EUSO is a UV telescope launched in 2019   and observing the Earth from the inside the Russian Zvezda module, through a nadir-facing UV-transparent.</p><p>It is composed of a Fresnel optics (25 cm diameter, 44 deg field of view) and a Multi Anode Photomultiplier focal surface (2304 pixels, 6km on the surface) with a single-photon counting capability and a sampling rate of 400kHz.</p><p>Its scientific objectives include the search for ultra-high energy cosmic rays (E>1e21eV), the study of  meteors and search for interstellar objects and Strange Quark Matter, the  mapping   of the Earth's night-time ultraviolet emissions, the search for space debris.</p><p>The characteristcs of the detector make it also well suited for the detection of TLEs, especially ELVES and the study of its development to extract spatial and temporal evolution.  In this article we will focus our attention on the observation of single and multi-ringed elves.</p>

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.
