ESA Euronews: Favourable winds for Aeolus

This edition of #Space comes from the coast of northern Norway, where we’ve come to the Andøya Space Centre to meet scientists working on a new satellite called Aeolus. This mission carries revolutionary laser technology to measure the wind around the entire globe. Lofted into orbit in August 2018 on a Vega rocket from French Guiana, Aeolus has only just begun its life in space. Engineers are now busy commissioning the mission to ensure that it will soon be ready to deliver novel data on winds. This will be used to improve our understanding of the atmosphere and to improve weather forecasts.

ESA Euronews: vent favorable pour Aeolus

Dans cette édition de #Space, notre reporter Jeremy Wilks se trouve sur la côte du nord de la Norvège, au Centre spatial d’Andøya. Il rencontre des scientifiques qui travaillent sur un nouveau satellite appelé Aeolus. Sa mission : mesurer pour la première fois, les vents autour de notre planète. Actuellement, l’équipe est en train de calibrer et de valider toutes les mesures qu’ils reçoivent de l’espace.

ESA Euronews: Kedvező szelek Aeolus számára

#Space című műsorunkban ezúttal Észak-Norvégiából jelentkezünk, ahol az Andøya űrközpontban tudósokkal találkoztunk, akik egy új műholdon, az Aeolus-on dolgoznak. Ez egyedülálló módon az űrből méri a Föld szeleit. A tudósok jelenleg azon dolgoznak, hogy kalibrálják és érvényesítsék a méréseket, amelyeket a föld körüli pályáról kapnak.
A Vega-rakéta robajával úttörő időjárási küldetés kezdődik: az Európai Űrügynökség régóta várt Aeolus-műholdját augusztus végén kilőtték az űrbe. A műhold gyorsan és alacsonyan repül, mindössze 320 kilométeres magasságban.

ESA Euronews: Vento favorevole per Aeolus

In questo episodio di #SPACE, siamo sulla costa del nord della Norvegia, ci troviamo al Centro Spaziale di Andøya per incontrare gli scienziati che lavorano su un nuovo satellite chiamato Aeolus (Eolo, il Dio del Vento) che – per la prima volta – sta misurando i venti su tutto il nostro pianeta. In questo momento stanno lavorando per calibrare e convalidare tutte le misurazioni che stanno ottenendo dallo spazio.

Aeolus quick steps to launch

This time-lapse video shows ESA’s #Aeolus satellite being prepared for liftoff. It includes shots from the cleanroom in France, its arrival by ship in French Guiana, preparations at Europe’s Spaceport in Kourou, roll out to the launch pad and, finally, liftoff on a Vega rocket on 22 August 2018.

Aeolus carries one of the most sophisticated instruments ever to be put into orbit. The first of its kind, the Aladin instrument includes revolutionary laser technology to generate pulses of ultraviolet light that are beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space.

Aeolus highlights

Lofted into orbit on a Vega rocket from Europe’s Spaceport in French Guiana on 22 August 2018, ESA’s Aeolus satellite will measure winds around the globe and play a key role in our quest to better understand the workings of our atmosphere. Importantly, this novel mission will also improve weather forecasting. The Aeolus carries one of the most sophisticated instruments ever to be put into orbit. The first of its kind, Aladin includes revolutionary laser technology to generate pulses of ultraviolet light that are beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space.

Prior to liftoff, the satellite had been at the spaceport for around six weeks being tested, fuelled, encased in the Vega rocket fairing, rolled out to the launch pad and hoisted into the launch tower. Vega lifted off at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August. Some 55 minutes later, the upper stage delivered Aeolus into orbit and contact was established through the Troll ground station in Antarctica at 00:30 CEST on 23 August. The satellite is being controlled from ESA’s European Space Operations Centre in Darmstadt, Germany. Controllers will spend the next few months carefully checking and calibrating the mission as part of its commissioning phase.

Aeolus liftoff replay

ESA’s Earth Explorer Aeolus satellite lifted off on a Vega rocket from Europe’s Spaceport in Kourou, French Guiana, at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August 2018. Aeolus carries one of the most sophisticated instruments ever to be put into orbit. The first of its kind, the Aladin instrument includes revolutionary laser technology to generate pulses of ultraviolet light that are beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space. By profiling the lowermost 30 km of the atmosphere, Aeolus will give scientists global information on the speed of the wind in near-real time. This will improve our understanding of how wind, pressure, temperature and humidity are interlinked. This new mission will also provide insight into how the wind influences the exchange of heat and moisture between Earth’s surface and the atmosphere. These aspects are important for understanding climate change. As well as advancing science and improving weather forecasts, data from Aeolus will be used in air-quality models to improve forecasts of dust and other airborne particles that affect public health.
