The E-USOC has finished the execution of its fifteenth experiment on board the ISS. The third one executed with the Transparent Alloys instrument. The METCOMP (Metastable Solidification of Composites: Novel Peritectic Structures and In-Situ Composites) experiment was a difficult one, but the scientists managed to fulfil all the objectives, and we will soon have a METCOMP-2 to process the samples that could not be uploaded this time. The METCOMP research focuses on layered structures in peritectic systems. The investigations of peritectic metallic systems show a wide range of possible microstructures: bands, islands, tree-like microstructures and coupled growth appear when the primary ...

La Agencia Europea del Espacio (ESA) ha aprobado la ejecución del experimento MarPCM (Marangoni Phase Change Materials), propuesto por el E-USOC, la Universidad de Mondragón y la Universitat Rovira i Virgili, para su ejecución a bordo de la Estación Espacial Internacional. El proyecto Mejora de la transferencia de calor en dispositivos PCM: Convección Marangoni y otras estrategias, aprobado recientemente por el Plan Estatal de Investigación Científica y Técnica y de Innovación, financiará el diseño y fabricación del modelo de ingeniería del instrumento. Está previsto que el modelo de ingeniería pueda ser entregado a la ESA en 2024 para comenzar ...

Crew intalling the cartidge with the scientific material in the MSG laboratory (NASA credits) The E-USOC has received the flight HDDs from the SETA (Solidification along a Eutectic Path in Ternary Alloys) experiment successfully executed on board the ISS in March-April 2020. The data contained in the disks has been processed and provided to the science team through the HRE Data Archive. SETA was the second experiment successfully performed by the E-USOC using the Transparent Alloys instrument. The aim of the experiment was to study the pattern formation during univariant eutectic reaction in directional solidification in transparent ternary alloys. ...

QBITO, the first Cubesat by Universidad Politécnica de Madrid was deployed last Thursday 25th of May, from the International Space Station (ISS). This Cubesat will study the lower thermosphere during the next 6 months as part of the European project QB50. The QB50 mission consists of a network of 36 CubeSats that will study the properties of the lower thermosphere. QBITO was deployed from the ISS at an initial circular orbit of 420 km altitude and 51° inclination. Due to atmospheric drag, its orbit will decay until the spacecraft burn in the atmosphere approximately in 6 months. Your ...

Seedling Growth-3 is the third part of the Seedling Growth Experiment series, using the plant Arabidopsis thaliana to investigate the effects of gravity on the cellular signaling mechanisms of light sensing in plants (phototropism), and to investigate cell growth and proliferation responses to light stimulation under microgravity conditions. The investigation also seeks to determine: the red light effect on blue-light-based phototropism and its effects the alterations in red-light-based phototropism of plants defective in essential components of auxin transport or lacking essential factors of cell growth and proliferation, the effects of a red light photostimulation on cell growth and proliferation under ...
