Pangaea-X is a test exercise that brings together geology, high-tech survey equipment and space exploration in environments similar to those found on other planets. Astronauts, scientists, operations experts and instrumentation engineers work side-by-side to advance European know-how of integrated human and robotics mission operations. An extension of ESA’s Pangaea geology training, the test campaign involves performing scientific investigations in extreme environments on Earth. The crew work with the latest technologies in instrumentation, navigation, remote sensing, 3D imaging and geoscience equipment, as well as testing operational concepts for surface missions where astronauts and robots work together. Pangaea-X participants explore the barren and dry landscape of Lanzarote in the Canary Islands, Spain, to prepare for the day when we set foot on other worlds. Known as the island of a thousand volcanoes, Lanzarote was chosen because of its geological similarity with Mars, such as a volcanic origin, mild sedimentary processes owing to a dry climate, hardly any vegetation and a well-preserved landscape.

Thanks to the wind, heat is distributed around the planet. Equatorial regions receive more heat from the Sun than other parts of the world. This leads to differences in air temperature, density and pressure, which in turn, cause the air to move – creating wind. This movement of air constitutes the general circulation of the atmosphere, transporting heat away from equatorial regions towards the poles, and returning cooler air to the tropics. The wind clearly plays an important role in weather forecasts, which in turn are not only important for planning our daily affairs, but vital for numerous commercial activities such as farming, fishing, transport, and for taking appropriate measures when extreme weather is on the horizon. Although weather forecasts have advanced considerably in recent years, there is a need for global wind measurements to improve them even further. ESA’s Aeolus mission will fill this gap by providing global wind-profiles in near-real time. The European Centre for Medium-Range Weather Forecasts will process these data and the data in their numerical weather prediction models, which will lead to better forecasting. ★ Subscribe: http://bit.ly/ESAsubscribe Learn more about Aeolus: http://bit.ly/AeolusESA

In August 2015 Comet 67P/Churyumov-Gerasimenko reached its closest point to the Sun along its orbit. ESA's Rosetta spacecraft was there to monitor the comet's activity as it reached a maximum, its frozen ices warmed by increasing solar radiation, escaping into space as streams of gas and dust. Rosetta's work may now be complete, but the comet continues along its 6.4 year orbit around the Sun, which takes it beyond the orbit of Jupiter at its furthest. In three years time it will return to our skies again, and this time may even be visible through binoculars. Colin Snodgrass of the Open University and ground-based observation campaign coordinator for the comet tells ESA Web TV how scientists are trying to match up what is seen in the wide views of the comet from Earth with the unique close-up images provided by Rosetta, and what astronomers are planning for future observations when it returns to our skies. With the comet making a closer pass to Earth than the last time, and at the same time being closest to the Sun, it will be brighter in our skies than during the Rosetta mission. Get your binoculars ready for late 2021! This is an ESA Web TV interview filmed in Rhodes, Greece during the 49th Rosetta Science Working Team Meeting in May 2018. The video contains imagery from a range of telescopes (indicated within) along with images from Rosetta's OSIRIS camera (credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA – CC BY-SA 4.0). ★ Subscribe: http://bit.ly/ESAsubscribe

Known to the crew as an EVA (extravehicular activity), each spacewalk provides a valuable opportunity to carry out repairs, test new equipment and even perform science experiments beyond the confines of a spacecraft. Exiting the International Space Station however, brings heightened risk and activities are planned down to the minute. In this clip, ESA astronaut Alexander Gerst and NASA astronaut Serena Auñón-Chancellor help NASA astronauts Feustel and Ricky Arnold prepare to step out into space for EVA 51. This spacewalk occurred on 14 June, 2018 – during Alexander Gerst’s Horizons mission. ★ Subscribe: http://bit.ly/ESAsubscribe Learn more: http://bit.ly/RecipeForASpacewalk

Laurence O'Rourke, ESA Rosetta Downlink Science Operations Manager, talks to ESA Web TV about the ongoing work on Rosetta's archive even years after the last data have been collected at Comet 67P/Churyumov-Gerasimenko.

A new function of the Planetary Science Archive, the online interface for scientists who use observations from ESA's planetary missions for their research, has recently been added, designed to facilitate the search process of data collected by ESA's missions past, present and future. ★ Subscribe: http://bit.ly/ESAsubscribe

The date is fixed: you are invited to the annual ESA Open Day at ESTEC, ESA’s technical heart in the Netherlands, on Sunday, 7 October. The theme this year is 'A voyage through space with Europe'. We'll have all ESA establishments represented on site, either with speakers giving talks or live link-ups to the different centres. You'll be able to meet astronauts, scientists and engineers, plus some special guests. You'll see how we design space missions, how we develop the technologies needed to go into space and how we simulate space on the ground. With the help of our colleagues from the other ESA centres, we'll complete the life-cycle of a mission and see how it is launched and controlled once in space!

What is a lunar eclipse? What is a solar eclipse? This short video explains the difference between these regularly occurring events that can be observed from Earth. The video uses a mix of ground- and space-based imagery of eclipses, including footage from the International Space Station, ESA's Proba-2 satellite and the Japanese-led Hinode satellite. Remember: never look directly at the Sun, even when partially eclipsed, without proper eye protection such as special solar eclipse glasses, or you risk permanent eye damage.

Orbiting Earth once every 90 minutes, the International Space Station soars into 16 sunrises and sunsets every single day. Many of these sunrises occur while the crew is working or sleeping, but ESA astronaut Alexander Gerst captured this stunning timelapse of a sunrise to share with us here on Earth. These photos were taken by Alexander at an interval of two per second and the video has been edited at 25 frames per second.
