“…Spectrometers to cover additional spectral regions (vacuum UV, mid-IR) are now in the planning stages or under development. Cubesat missions and potential technologies for Earth observation have recently been surveyed (Selva and Krejci 2012); the now-emerging trend towards the development and flight of 6U cubesats is a boon to this application, as it provides adequate volume for modest but capable optical systems, including deployable telescopes, to enable remote observations of Earth or the cosmos (Tsitas and Kingston 2010).…”

The space environment is regularly used for experiments addressing astrobiology research goals. The specific conditions prevailing in Earth orbit and beyond, notably the radiative environment (photons and energetic particles) and the possibility to conduct long-duration measurements, have been the main motivations for developing experimental concepts to expose chemical or biological samples to outer space, or to use the reentry of a spacecraft on Earth to simulate the fall of a meteorite. This paper represents an overview of past and current research in astrobiology conducted in Earth orbit and beyond, with a special focus on ESA missions such as Biopan, STONE (on Russian FOTON capsules) and EXPOSE facilities (outside the International Space Station). The future of exposure platforms is discussed, notably how they can be improved for better science return, and how to incorporate the use of small satellites such as those built in cubesat format.

“…Assuming that all helices have cross section of height a and width b, the radius R SI of the structure at the end of Stage I folding can be estimated by equating the arc-length of the original helix to a helix with a pitch equal to the cross-section height (4) The minimum stowed height H of this structure can be estimated from (5) where N is the number of turns of each helix, n is the number of helices (e.g. 2,4,8). In addition to the geometric analysis presented here, for any chosen set of cross section dimensions and material properties, a detailed analysis needs to be carried out to confirm that folding the structure does not cause damage or permanent deformation of the helices.…”

“…As part of a push for greater capabilities in small satellites, solar sails, space weather monitors and space telescopes have been recently developed for the CubeSat platform [1][2][3]. However, the comparatively slow bit rates between these satellites and ground stations limits downlink intensive applications, such as Earth imaging or relaying communications [4]. A high gain, wideband deployable antenna suitable for small satellites could increase their downlink speed and enable capabilities found on much larger satellites.…”

This paper explores the behavior of a self-deploying helical pantograph antenna for CubeSats. The helical pantograph concept is described along with concepts for attachment to the satellite bus. Finite element folding simulations of a pantograph consisting of eight helices are presented and compared to compaction force experiments done on a prototype antenna. Reflection coefficient tests are also presented, demonstrating the operating frequency range of the prototype antenna. The helical pantograph is shown to be a promising alternative to current small satellite antenna solutions.

“…Taking into account studies such as Selva and Krejci (2012) or Sandau (2008), the Universidad Sergio Arboleda is carrying out its second satellite mission called Libertad 2, which consists of the development and implementation of a 3U nanosatellite designed under the CubeSat standard. This mission's main goal is to validate the development of a Remote Sensing System (RSS) prototype, which will open the field for academic researches in Colombia based on the obtained images; these researches may focus on the analysis of land use for the agricultural sector, water resource analysis, planning of urban growth, among others.…”

ABSTRACT:The main goal of the Libertad 2 mission is to take images of the Earth's surface in the visible spectrum with a multispectral sensor and send them as a Bayer array. To carry out the reconstruction in land of these images and to view them in a RGB color model, it is necessary to use a color interpolation algorithm to determine the values of the different channels of color in each pixel. This document presents an analysis of five chromatic interpolation algorithms (Nearest Neighbor, Adaptive Color Plane, Bilinear, Smooth Hue Transition and Median Based). The analysis also includes the identification of image evaluation algorithms without reference and the artifacts (False Color Measure, Blur Metric and Chromatic and Achromatic Zipper). Finally, the analysis results of the chromatic interpolation algorithms and the selection of the most suitable algorithm for the Libertad 2 satellite mission data are presented.
