Thomas Pesquet au salon du Bourget

Français L'astronaute de l'ESA Thomas Pesquet, de retour sur terre, répond depuis le salon du Bourget aux questions à propos de la mission Proxima durant laquelle il a passé six mois à bord de la station spatiale internationale. Au cours de la mission, il a travaillé sur plus de 60 expériences scientifiques pour l'ESA, pour le CNES et pour les partenaires de l'ISS.

English ESA astronaut Thomas Pesquet, who recently returned from the International Space Station, answers questions from the public at the Paris Air and Space Show 2017 about his six-month Proxima mission in which he took part in over 60 scientific experiments for ESA and France’s space agency CNES and the ISS partners.

France

Sentinel-3 gives us a nearly cloud-free view of France and the surrounding countries.

Much of the landscape is covered with agricultural features. In fact, farmers manage nearly half of Europe’s land area. While agriculture brings benefits for economy and food security, it puts the environment under pressure. Satellites can help to map and monitor land use, and the information they provide can be used to improve agricultural practices.

On the right side of the image we can see the snow-covered Alps, while the Pyrenees mountains are visible near the bottom.

To the west of the Alps a green area of mountains and plateaus is visible, called the Massif Central. The region has more than 400 volcanoes, considered by scientists to be extinct.

On the right side of the image, the light brown area flanked by dark areas is the Rhine River forming part of France’s border with Germany. The dark area to the east is the Black Forest, while the dark area to the west are the Vosges Mountains.

Just above the centre we can see Paris – the site of ESA’s headquarters as well as the Paris Air & Space Show taking place this week.

This image was captured by the Copernicus Sentinel-3A satellite’s Ocean and Land Colour Instrument on 7 April 2017. The instrument monitors ocean ecosystems, supports crop management and agriculture, and provides estimates of atmospheric aerosol and clouds – all of which bring significant benefits through more informed decision-making.

Signing ceremony

Signing the contract to build and test another eight Galileo satellites on 22 June 2017, at the ESA Pavilion during the Paris Air and Space Show on 22 June 2017. It was awarded to a consortium led by prime contractor OHB, with Surrey Satellite Technology Ltd overseeing their navigation platforms. ESA’s Director of the Galileo Programme and Navigation-related Activities, Paul Verhoef (right), signing the contract of behalf of the European Commission, shakes hands with the CEO of OHB, Marco Fuchs beside OHB Navigation Director Wolfgang Paetsch, in the presence of ESA Director General Jan Woerner (in background) and the EC’s Deputy Director-General for Internal Market, Industry, Entrepreneurship and SMEs, Pierre Delsaux.

The creation of ESA_Lab@HEC, the first ESA_Lab@ between ESA and HEC Paris

The ESA-Lab@HEC agreement has been signed by Peter Todd, Dean, HEC Paris and Jan Woerner, ESA Director General, at ESA’s pavilion at Le Bourget on Thursday 22 June 2017 during the Paris Air and Space Show.

ESA_Lab@HEC Paris is a cooperation scheme to intensify research, development and outreach between ESA and HEC Paris. Given the possibility to work on interesting and challenging ideas, students from all degree programmes will be enriched with the knowledge of how disruptive, future-oriented space-based solutions can be developed for the benefit of society and economy. The project is part of the larger ESA_Lab@ platform newly established with the aim of intensifying collaboration with academia.

Catching up with space weather

Speaking at the 52nd International Air and Space Show in Paris, ESA's Juha-Pekka Luntama explains what space weather is and why it's a potential hazard.

Our Sun emits magnetised plasma – ‘solar wind’ – and periodically ejects billions of tons of matter threaded with a magnetic field in colossal coronal mass ejections; these influence the space environment and can cause geomagnetic storms, affecting satellites, infrastructure on ground and human health.

In Europe’s economy today, numerous sectors are potentially affected by space weather, ranging from space-based telecommunications, broadcasting, weather services and navigation through to power distribution and terrestrial communications, especially at northern latitudes.

Juha-Pekka is responsible for development of a new space-weather warning capability within ESA's Space Situational Awareness (SSA) programme.
