The analysis of information on the stability of the electronic component base (ECB) in the development of radio-electronic equipment (REE) of spacecraft (spacecraft) is an important and urgent task. The paper considers the main components of the approaches of foreign organizations developing radio space technology to ensure its radiation resistance. The design approaches of Thales Alenia Space, Airbus Defense and Space, and the European Space Agency are presented. The article outlines the main directions for optimizing the procedures for the preliminary selection of ECB, which consist in ensuring the required resistance of REE SC at the ECB level with ensuring the reliability of data on durability, in minimizing the costs of applying resistance enhancement measures (through the use of a promising ECB with increased resistance characteristics), to replace ECB.

AbstractLithopanspermia Theory has suggested that life was transferred among planets by meteorites and other rocky bodies. If the planet had an atmosphere, this transfer of life had to survive drastic temperature changes in a very short time in its entry or exit. Only organisms able to endure such a temperature range could colonize a planet from outer space. Many experiments are being carried out by NASA and European Space Agency to understand which organisms were able to survive and how. Among the suite of instruments designed for extraplanetary exploration, particularly for Mars surface exploration, a Raman spectrometer was selected with the main objective of looking for life signals. Among all attributes, Raman spectroscopy is able to identify organic and inorganic compounds, either pure or in admixture, without requiring sample manipulation. In this study, we used Raman spectroscopy to examine the lichen Squamarina lentigera biomarkers. We analyse spectral signature changes after sample heating under different experimental situations, such as (a) laser, (b) analysis accumulations over the same spot and (c) environmental temperature increase. Our goal is to evaluate the capability of Raman spectroscopy to identify unambiguously life markers even if heating has induced spectral changes, reflecting biomolecular transformations. Usnic acid, chlorophyll, carotene and calcium oxalates were identified by the Raman spectra. From our experiments, we have seen that usnic acid, carotene and calcium oxalates (the last two have been suggested to be good biomarkers) respond in a different way to environmental heating. Our main conclusion is that despite their abundance in nature or their inorganic composition the resistance to heat makes some molecules more suitable than others as biomarkers.

In the course of operation spacecrafts are exposed to ionizing radiation from outer space. The electronic component base (ECB) used in creating onboard radio-electronic equipment of universal space platforms does not always correspond to the external operating conditions in terms of radiation resistance for some spacecraft orbits due to a number of technical and/or economic reasons. One method to increase the radiation resistance of onboard equipment is to install additional mass protection in the form of screens on the whole equipment or local screens on individual critical radio and electronic components. The article describes the design of additional radiation protection of the geostationary spacecraft scientific equipment complex for adaptation to the radiation conditions of operation in orbits of the “Molniya” type. The solution of the problem involves several preliminary steps, namely: determining the radiation conditions for the spacecraft operation in the target orbit, estimating the local absorbed doses at the locations of the onboard equipment, estimating absorbed doses directly in the electronic component base of the equipment and analyzing the radiation resistance. Designing the radiation complex of scientific equipment was based on the values of the radiation resistance of the equipment and its components, as well as the calculated values of the local absorbed doses in the components

Outer space in Pakistan is a trivial notion, and the idea has become less concerning for the authorities let alone the general masses. For decades, this field has been void of any particularly outstanding and significant development in the country with only a handful of satellites launched in outer space. Where the world has progressed in space technology utilizing it for exploring, exploiting, and now even racing to dominate the global common, that is the outer space, Pakistan‟s space program has been lagging and misses the opportunities that a robust outer space program provides, all the while ignoring the threats that arise from a weak space program. The significance of outer space has increased over the years in both civilian and military domains, where militarization outer space is now being transformed into a weaponization phenomenon. The space race that began in the Asian region with the Soviet Union inspired periphery states such as Pakistan to join space faring. Pakistan was the third country in Asia to establish its space agency; however, over time, it has lost its acclaimed position. Over time, it has grown weak with minimal research and development (R&D) in the field. Pakistan‟s space program lacks a place in the literature, and academic discussions and this study aims at filling that gap by analyzing the strengths, weaknesses, threats, and opportunities for the space program of Pakistan.

Background Headache is a common symptom during space travel, both isolated and as part of space motion syndrome. Head-down-tilted bed rest (HDTBR) studies are used to simulate outer space microgravity on Earth, and allow countermeasure interventions such as artificial gravity and training protocols, aimed at restoring microgravity-induced physiological changes. Objectives The objectives of this article are to assess headache incidence and characteristics during HDTBR, and to evaluate the effects of countermeasures. Methods In a randomized cross-over design by the European Space Agency (ESA), 22 healthy male subjects, without primary headache history, underwent three periods of –6-degree HDTBR. In two of these episodes countermeasure protocols were added, with either centrifugation or aerobic exercise training protocols. Headache occurrence and characteristics were daily assessed using a specially designed questionnaire. Results In total 14/22 (63.6%) subjects reported a headache during ≥1 of the three HDTBR periods, in 12/14 (85.7%) non-specific, and two of 14 (14.4%) migraine. The occurrence of headache did not differ between HDTBR with and without countermeasures: 12/22 (54.5%) subjects vs. eight of 22 (36.4%) subjects; p = 0.20; 13/109 (11.9%) headache days vs. 36/213 (16.9%) headache days; p = 0.24). During countermeasures headaches were, however, more often mild ( p = 0.03) and had fewer associated symptoms ( p = 0.008). Conclusions Simulated microgravity during HDTBR induces headache episodes, mostly on the first day. Countermeasures are useful in reducing headache severity and associated symptoms. Reversible, microgravity-induced cephalic fluid shift may cause headache, also on Earth. HDTBR can be used to study space headache on Earth.

In the absence of systematic structural monitoring to support adequate maintenance standards, many existing infrastructures may reach unacceptable quality levels during their life cycle, resulting in significant damage and even potential failure. The metropolitan area of the Gulf of Salerno (Italy), served by a complex multimodal transport network connecting the port area to the roads and railways surrounding the urban area, represents an important industrial and commercial hub at the local and international scale. This particular scenario, developed in a complex morphological and geological context, has led to the interference and overlapping of the transport network (highway, railway, main and secondary roads) that run through the piedmont area north of the port. Given the relevance of the area, our research aims to highlight the capabilities of the persistent scatterer interferometry (PSI) technique, belonging to the group of differential interferometric synthetic aperture radar (SAR), to extract space–temporal series of displacements on ground points or artifacts with millimeter accuracy useful to understand ongoing deformation processes. By using archived data from the European Space Agency missions, i.e., ERS1/2 (European remote-sensing satellite) and ENVISAT (environmental satellite), and the most recent data from COSMO-SkyMed constellations, it was possible to collect a 28-year dataset that was used to spatially analyze displacement patterns at a site-specific scale to check the stability of viaducts and embankments, and on a larger scale to understand the activity of the surrounding slopes. Despite the different resolution and subsequently the ground density, the analysis of the different datasets showed a spatiotemporal consistency in the displacement patterns that concerned two subareas showing significant annual velocity trends, one northeast of the city and the second in the port area. The analysis presented in this paper highlights how a complex geologic area, combining slope movements and various fault systems, could be a major concern for the stability of the overlying infrastructure and also the role that a PSI analysis can play in remotely monitoring their behavior over long periods of time.

ABSTRACTFuture science missions of the European Space Agency (ESA) to the inner part of the solar system will require the use of materials at an extreme radiation and temperature environment. A major concern regarding the selection of these materials is the thermal behaviour and the thermal stability. In this paper ways are shown to assess the thermal endurance of polymers by kinetic modelling. Two commonly used kinetic models, the one following the ASTM E 1641 and ASTM E 1877 standards and the other following the Model Free Kinetics (MFK) approach, are presented and compared to each other with the given example of two competing polyimide films, Kapton HN® of DuPont and Upilex S® of Ube Industries1, which were tested within ESA's critical materials technology program.

MAGNA STEYR Space Technology was authorised by the European Space Agency (ESA) to develop to breadboard level a low mass micro engineered device able to change the heat rejection capability of a radiator and to protect it against external radiation variations. Previous works of MAGNA in the field of thermal control systems was the thermal design, manufacturing and verification of the ROSETTA thermal Louvres [5]. Thermal Louvres in satellite applications are used for thermal control to avoid overheating of the new generation satellites by exposed or shadowed radiator area. The closing and opening of the louvers wings is performed by thermal controlled actuators. The Louvres system is designed to be controlled by solar radiation. The challenge in the project was the design, manufacturing and verification of louvers with less mass but higher efficiency than current louvers.


This chapter describes the historical background, basic provisions, main contents, and key changes of the 1968 Space Rescue Agreement (Title: Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched Into Outer Space). The author points out the legal problems and the solution on the 1965 Rescue Agreement. The Rescue Agreement requires that any state party that becomes aware that the personnel of a spacecraft are in distress must notify the launching authority and the Secretary General of the United Nations. The UN General Assembly adopted the text of the Rescue Agreement on 19 December 1967 through Resolution 2345 (XXII). The Agreement opened for signature on 22 April 1968, and it entered into force on 3 December 1968. As of January 2019, 98 states have ratified the Rescue Agreement, 23 have signed, and three international intergovernmental organizations (the European Space Agency, the Intersputnik International Organization of Space Communications, and the European Organisation for the Exploitation of Meteorological Satellites) have declared their acceptance of the rights and obligations conferred by the agreement.
