Μια ξεχωριστή μέθοδος που αλλάχει τα δεδομένα. Αυτόν τον μήνα το Space βρίσκεται στο Πλύμουθ της Νότιας Αγγλίας και στη Νορμανδία της Βόρειας Γαλλίας για να εξετάσει πώς οι δορυφόροι χρησιμοποιούνται σε καινοτόμες νέες μεθόδους ώστε να αντιληφθούμε καλύτερα την θάλασσα γύρω από την ακτογραμμή. Ο Μπομο Μπρούιν ίναι πρωτοπόρος σε μια νέα τεχνική στη δορυφορική ωκεανογραφία - κάνοντας σέρφινγκ. Η ιδέα του είναι να χρησιμοποιήσει την σανίδα του για να μετρήσει τη θερμοκρασία της θάλασσας και στη συνέχεια να χρησιμοποιήσει τα στοιχεία αυτά για να ερμηνεύσει καλύτερα τα δεδομένα του ευρωπαϊκού δορυφόρου Sentinel-3. ★ Εγγραφείτε: http://bit.ly/ESAsubscribe

Diese Folge von Space hat viel mit Wasser zu tun. Hier in Nordfrankreich besuchen wir Forscher, die sich mit schädlichen Algen beschäftigen und in Südengland treffen wir einen surfenden Wissenschaftler. Alle verwenden Sentinel-Satellitendaten, um den Überblick zu behalten. Die "Augen im Weltall" verändern unser Verständnis für die Ozeane. Bob Brewin ist der Erfinder einer neuen Technik in der Satelliten-Ozeanographie - er arbeitet auf dem Surfbrett. Er hatte die Idee, mit seinem Board die Temperatur der Meeresoberfläche zu messen, um damit die Daten des europäischen Satelliten Sentinel-3 besser interpretieren zu können. Und es gibt einen Grund für diese Messungen erklärt Bob Brewin, Wissenschaftler am Plymouth Marine Labor. ★ Sbonnieren: http://bit.ly/ESAsubscribe

ESA’s latest mission has completed its in-orbit commissioning. The cereal-box-sized GomX-4B performed a transfer of data across hundreds of kilometres of space from its Danish twin. Both of the nanosatellites were built by GomSpace in Denmark. GomX-4A, financed by the Danish Ministry of Defence, is focused on monitoring and imaging Denmark’s Arctic territory. The ESA-backed GomX-4B is testing a micro-propulsion system as well as an inter-satellite radio link with its counterpart. It also carries other technology payloads, including a hyperspectral imager. CubeSats are small satellites based around standard 10cm cubic units, but these two ‘six-unit’ CubeSats still required weeks of in-orbit testing once they reached space, just like full-sized missions. GomSpace showed the satellites in action for the first time during a live press conference from their Aalborg headquarters on 12 April 2018. The retrieval process from GomX-4A to GomX-4B – and vice versa – down to Earth went according to schedule, confirming the satellite pair can share both data and images and send them home.

It’s one of the deepest ‘swimming pools’ in Europe, but for three years has been helping preparations for a human return to the Moon. ESA’s Neutral Buoyancy Facility at the European Astronaut Centre has been the site of the ‘Moondive’ study, using specially weighted spacesuits to simulate lunar gravity, which is just one sixth that of Earth. The three-year study took place in the Centre’s 10-m deep Neutral Buoyancy Facility (NBF) near Cologne in Germany. This is one of four such immersion tanks worldwide – the others are in the United States, China and Russia – and is used to train astronauts for ‘extra vehicular activity’ (EVA), also known as spacewalks. With International Space Station operations moving towards an international lunar return in the late 2020s, ESA’s NBF has been used to investigate moonwalk procedures for the lunar surface. Moondive was run by a consortium led by the French company, COMEX, which specialises in human and robotic exploration of extreme environments. Footage is also seen from precursor project Moonwalk, including simulated EVAs off the coast of Marseilles, funded by the European Commission’s Seventh Framework Programme.

Every week, on average, a substantial, inert satellite drops into our atmosphere and burns up. Monitoring these reentries and warning European civil authorities has become routine work for ESA’s space debris experts. Each year, about 100 tonnes of defunct satellites, uncontrolled spacecraft, spent upper stages and discarded items like instrument covers are dragged down by Earth’s upper atmosphere, ending their lives in flaming arcs across the sky. Some of these objects are big and chunky, and pieces of them survive the fiery reentry to reach the surface. Our planet, however, is a big place, mostly covered by water, and much of what falls down is never seen by anyone, sinking to the bottom of some ocean, or landing far from human habitation. While still in orbit, these and many other objects are tracked by a US military radar network, which shares the data with ESA, since Europe has no such capability of its own.It’s the task of ESA’s Space Debris team to look at these data and issue updates to ESA Member States and partner civil authorities around the globe.

A compilation of public contributions to the SPAC3 social artwork project. They were made using ‘SPAC3’ app, which allowed users to select and combine images taken by ESA astronaut Paolo Nespoli from space with their own photos. This activity was intended to draw attention to the wellbeing of our planet, and was inspired by the Sustainable Development Goals of the United Nations. These provided the basis for Paolo’s choice of photos, and the app users could respond with their own photos on the same theme. As a social artwork project, SPAC3 demonstrated that the two worlds of art and science can work together with the common objective of highlighting issues affecting our planet, and showed how involving a wider public could contribute to the vision and become part of this collective work. This joint initiative was made possible via a partnership between ESA and RAM radioartemobile, in cooperation with ASI and Cittadellarte-Fondazione Pistoletto. Credits: RAM radioartemobile

Collecting information on water resources at over large areas is often difficult. This limits national and river-basin water managers’ ability to make the appropriate decisions. Satellites can fill this information gap with timely observations. Since 2008, ESA has been working closely with international financing institutions and client states to harness the benefits of Earth observation for global sustainable development. Earth Observation for Sustainable Development (EO4SD) is a new ESA initiative that aims to increase the uptake of satellite information in regular development operations nationally and internationally.
