Vega Flight VV12 - ADM-Aeolus - August 22, 2018
« on: 01/02/2012 03:11 PM »
ESA's wind mission ADM-Aeolus

The Earth Explorer Atmospheric Dynamics Mission (ADM-Aeolus) will provide global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.
 
Although there are several ways of measuring wind from a satellite, ADM-Aeolus will utilise the active Doppler Wind Lidars (DWL) method. This is the only method that has the potential to provide the required data globally, from direct wind observations. In addition, a DWL will provide information on cloud top heights, vertical distribution of cloud, aerosol properties, and wind variability. This information is a useful by-product of the DWL method.

An improved model of the Earth’s climate and atmosphere will lead to progress in numerical weather prediction (NWP), especially concerning long-term forecasting. It is widely recognised that a new global atmospheric observing system, such as ADM-Aeolus, will have a great effect upon operational weather forecasting. The provision of detailed wind profiles will also benefit scientists involved with climate research, allowing for greater accuracy in the numerical modelling of tropical regions in particular.

Aeolus

The first laser transmitter has completed an endurance test in near-vacuum conditions with overall positive results. Specific performance issues are being analysed and refurbishment will be carried out before formal qualification for flight.

The master oscillator of the second flight laser transmitter is aligned and tests show good performance.

Refurbishment of the transmitting and receiving optics has almost been completed and the delta-qualification of the main optical bench is now in preparation.

Aeolus carries a pioneering instrument called Aladin that uses laser light scattering and the Doppler effect to gather data on wind.
 
The laser generates high-energy UV light, which is beamed towards Earth through a telescope. As the light travels down through the atmosphere, it bounces off molecules of gas, particles of dust and droplets of water.

This scatters some of the light in all directions, including back to the satellite where it is recorded by Aladin.
 
By comparing the shift in frequency of the received light from the transmitted light caused by the Doppler effect, the motion of the molecules in the atmosphere can be measured, revealing wind velocity.
 
The laser transmitter is being developed by Selex-ES in Italy.

Aladin

A technical view of the ADM-Aeolus satellite’s Aladin instrument. It incorporates two powerful lasers, a large telescope and very sensitive receivers. The laser generates UV light which is beamed towards Earth. This light bounces off air molecules and small particles such as dust, ice and droplets of water in the atmosphere. The fraction of light that is scattered back towards the satellite is collected by Aladin’s telescope and measured. The movement of the air molecules, particles or droplets cause this backscattered light to change frequencies slightly. By comparing these frequencies with the original laser, the winds below the satellite can be determined.

The mission will provide accurate and timely profiles of the world’s winds as well as information on aerosols and clouds. These profiles will not only advance our understanding of atmospheric dynamics, but will also offer much-needed information to improve weather forecasts.

Aladin ready for Aeolus

After many years in development, Aladin – the Doppler wind lidar to be carried on the Aeolus satellite – is ready to be shipped from Toulouse, France, to the UK to be installed on the satellite in preparation for liftoff by the end of 2017. Aeolus will be the first satellite mission to probe the wind globally. These vertical slices through the atmosphere, along with information on aerosols and clouds, will advance our knowledge of atmospheric dynamics and contribute to climate research.

Its state-of-the art Aladin instrument incorporates two powerful lasers, a large telescope and very sensitive receivers. The laser generates ultraviolet light that is beamed towards Earth. This light bounces off air molecules and small particles such as dust, ice and droplets of water in the atmosphere. The fraction of light that is scattered back towards the satellite is collected by Aladin’s telescope and measured.

Today, ESA and Arianespace signed a contract to secure the launch of the Aeolus satellite. With this milestone, a better understanding of Earth’s winds is another step closer.

The contract, worth €32.57 million, was signed at ESA headquarters in Paris, France, by ESA’s Director of Earth Observation Programmes, Josef Aschbacher, and CEO of Arianespace, Stéphane Israël.

Josef Aschbacher said, “Aeolus has certainly had its fair share of problems. However, with the main technical hurdles resolved and the launch contract now in place, we can look forward to it lifting off on a Vega rocket from French Guiana, which we envisage happening by the end of 2017.”

World's First Weather-Cracking Wind Satellite Aeolus to Improve Future Forecasts
https://sputniknews.com/europe/201701191049770279-europe-weather-satellite-study/
A team of scientists at the Airbus Defense and Space Center in the UK, have bid farewell to a satellite this week, which will allow for more accurate weather predictions, as it was shipped to France for testing, before being launched into space.

The satellite, called Aeolus and named after the ruler of the winds in Greek mythology, is a one of a kind instrument that will study Earth's wind patterns from space, using a powerful laser pulse called Aladin.

Dr. Ralph Cordey,  one of the lead researchers on the Aeolus project, said that the instrument was built to measure the wind in the Earth's atmosphere from space and it will be the first instrument that will be able to do this.

"The spacecraft will orbit around the Earth and the satellite will carry a laser that fires pulses of ultraviolet light. It carries a telescope that will pick up the faint reflective signals of that light that are scattered by the gas molecules in the Earth's atmosphere and also dust particles and aerosols. It will use the Doppler effect and decide to access the velocity of the dust gas that scatters the signals, so it measures the speed of the air," Dr. Ralph Cordey told Sputnik.

Aeolus will orbit the Earth for 3.5 years and during that period it will be used by the Met Office — UK's national weather service — to improve the forecast.

Dr. Cordey and his team hope that Aelous will help reduce the uncertainties in understanding weather patterns. The scientists also expect that the satellite will have a lot of impact on the world's tropical areas.

"Basically weather forecasts use computers that take in observations from satellites and that goes into a big model that predicts what will happen, so by adding this data, that is not in the model at the moment, we hope to improve the forecasts," Dr. Cordey told Sputnik.

As a result, it is believed that weather prediction will be more accurate. According to Dr. Cordey, the team expect that it will be a lot more precise and we should see this as soon as the satellite is launched.

The idea originated from a mission back in the 1990s. Dr. Cordey said that there have been many attempts and ideas to put lasers into space, and over time the technology to do this has improved.

The satellite project, which has been in production since 2003, is a high-powered system and has been worked on by several different teams in various locations around the world.
"The laser was developed by a team in Italy, the telescope, a team in Toulouse and the satellite that carries the big instrument was developed in Stevenage [UK]," Dr. Cordey told Sputnik.

"Then there is the Assembly Integration and Test — that's when you are putting together and testing the instrument to see that it works.

"All the testing is not yet completed and the satellite will be transported to Toulouse [France] for testing to make sure it can stand up to the vibrations of going on a rocket. Then it will go to Belgium to be put in a vacuum chamber to see if it can survive in the vacuum of space. Finally, it will be launched from South America into space," Dr. Cordey added.

According to Dr. Cordey and his team, the UK will provide cutting-edge technology, combined with world-leading weather forecasting, which will make it a leading weather research hub.
NASA and NOAA are watching this mission closely ahead of formulating the design for new generation weather satellites.

The preparation of aeolus for his departure to French Guyana is progressing normally. It  seems to be sleeping but aeolus is working hard. Operators and software engineers are correcting software and procedures errors that were encountered during aeolus functional tests. Correcting is mostly about verifying that the corrections work in all imaginable situations ! Cables that show aeolus as under perfusion actually provide the stimuli that it would receive if it was in orbit.

The date of aeolus launch is (finally) official. It will be August 21, 2018, at 18:20 Kourou time, 23:20 Paris time. aeolus will be put into orbit by the 12th model of Vega, the smallest launcher that is available to Arianespace in French Guiana. The launch campaign will begin the very first days of July. This blog will follow the day-to-day campaign.
In the meantime, aeolus functional tests are running without any major hitch.

N° 10–2018: CALL FOR MEDIA: LAST LOOK AT ESA’S AEOLUS WIND SATELLITE

17 May 2018

Carrying novel laser technology to measure winds around the globe, ESA’s Aeolus satellite will soon be shipped to French Guiana for liftoff. This is the first time that UV laser technology will be used for such spaceborne measurements. Before it is packed up, media representatives are invited to see this extraordinary satellite in the cleanroom at Airbus Defence and Space’s facilities in Toulouse, France, on 5 June 2018.

By probing the atmosphere with a powerful laser, Aeolus is set to advance our understanding of tropical dynamics and processes relevant to climate variability, and, importantly, improve weather forecasts.

Many aspects of our lives are influenced by the weather, so it goes without saying that accurate forecasts are important for commercial undertakings such as farming, fishing, construction and transport – and, in general, forecasts make it easier to plan the days ahead. Although forecasts have advanced considerably in recent years, meteorologists urgently need global wind-profile data to improve them even further.

The press event not only includes a visit to the cleanroom for a unique view of this latest space technology – the first wind lidar ever to be launched, but it also includes briefings by mission experts from ESA and from Airbus and the opportunity to conduct interviews.

Before ESA’s Aeolus satellite is packed up and shipped to French Guiana for liftoff in August, media representatives had the chance to see this wind measuring Earth Explorer satellite standing proud in the cleanroom.

Like all of the Earth Explorers, Aeolus was built to show how cutting-edge space technology can shed new light on the intricate workings of our planet.

This pioneering satellite uses powerful laser technology that probes the lowermost 30 km of our atmosphere to yield vertical profiles of the wind as well as information on aerosols and clouds.

This will not only improve our understanding of how the atmosphere works and contribute to climate change research, but will also help to predict extreme events such as hurricanes and El Niño.

While Aeolus is set to advance science, it will also bring considerable benefits to society by improving weather forecasts.

Aeolus sets sail

15 June 2018

Today is Global Wind Day, which couldn’t be more apt for ESA’s Aeolus wind satellite to begin its voyage to the launch site in French Guiana. And, while almost all satellites journey by aircraft, Aeolus is different, it’s going by ship.

Scheduled to liftoff on a Vega rocket on 21 August at 21:20 GMT (23:20 CEST) from Europe’s spaceport near Kourou, Aeolus carries one of the most sophisticated instruments ever to be put into orbit.

This pioneering mission uses powerful laser technology that probes the lowermost 30 km of our atmosphere to yield vertical profiles of the wind and information on aerosols and clouds.

Since the instrument is sensitive to pressure change, ESA and Airbus Defence and Space engineers decided that the safest way for it to journey from France, where it has been going through testing, to French Guiana would be by ship.

With liftoff less than three weeks away, ESA’s Aeolus satellite has been fuelled and is almost ready to be sealed within its Vega rocket fairing.

Quote
This pioneering mission is set to provide global wind-profile data, using powerful laser technology that probes the lowermost 30 km of our atmosphere to yield vertical profiles of the wind and information on aerosols and clouds.

The mission will improve our understanding of how atmosphere dynamics work and contribute to climate change research. At the same time, it will also help to predict extreme events such as hurricanes and help us to better understand and model large-scale wind patterns driving weather such as El Niño.

It is also expected to bring considerable benefits to society by improving weather forecasts. Its global wind measurements, delivered almost in real time, are exactly what meteorological centres are looking for to improve their forecasts.

Press Release
N°20-2018
Paris, 10 August 2018

 
Call for Media: Aeolus launch event


ESA’s Aeolus mission, which will use revolutionary laser technology to measure winds around the globe, is set for launch on 21 August from Europe’s Spaceport at Kourou in French Guiana. Media representatives are invited to the European Space Operations
Centre (ESOC) in Darmstadt, Germany, to follow the launch of this latest Earth Explorer satellite.

This pioneering mission uses powerful laser technology that probes the lowermost 30 km of our atmosphere to yield vertical profiles of the wind and information on aerosols and clouds – a completely new approach to measuring the wind from space.

Although our daily weather forecasts include information about the wind, there is a lack of direct measurements. Scientists and meteorologists need accurate and timely wind data to understand systems that influence our weather and climate, and to improve
forecasts. Aeolus is the first satellite to do just this.

Liftoff on a Vega rocket is scheduled for 21 August at 23:20 CEST (21:20 GMT).

For latest news and information on Aeolus, visit: www.esa.int/aeolus
http://www.esa.int/aeolus 

The Twitter hashtag to follow is #Aeolus

Follow the Aeolus launch live at ESA’s European Space Operations Centre Starting at 22:00 CEST, the programme comprises short briefings about the scientific goals of this new wind mission, its sophisticated laser instrument and how the data will be
used, as well as live updates from the teams in ESOC’s Main Control Room and from the launch pad in Kourou. Mission experts will be available for individual interviews.


Programme (all times are local time in Darmstadt (CEST))

20:30  Doors open

21:15   Q&A opportunity for media in ESOC’s Control Centre

22:00  Start of the event programme in ESOC’s Press Centre:

Welcome addresses from Head of ESA–ESOC and Director of Operations, Rolf Densing, and Head of ESA Earth Observation Projects, Philippe Goudy, followed by talks by mission and meteorological specialists

22:50  Live from Kourou 

23:20  Aeolus lifts off (live transmission)

23:35  Break/light buffet

00:30Coverage from Kourou resumes for acquisition of signal (AOS information is not conclusive…)

01:00  Programme ends


Accreditation

Aeolus on a roll

After being sealed within its Vega rocket fairing, Aeolus has been rolled out to the launch pad at Europe’s Spaceport in Kourou, French Guiana. Here it will join the rest of the rocket in the launch tower in preparation for liftoff on 21 August at 21:20 GMT (23:20 CEST).

A mission to measure winds is delayed by strong winds. Oh... the irony... ;)

Its related the wind direction/speed in relation to the possible debris, these have been reevaluated after VA241.

However, the PR doesnt state if its linked to upper level winds or linked to safety....

Article by Jonathan Amos.

Aeolus space laser set to map Earth's winds

Quote
Aeolus is just a one-off demonstration mission, which raises the question of what happens when it inevitably reaches the end of its working life.
If it delivers on its promise, forecasters will be loath to lose the advantage. But it would not be Esa's role to produce a second spacecraft.
The agency is in the business of R&D, of trialling new concepts. It would be down to others to fund follow-on missions.
In Europe, this would fall either to Eumetsat, the intergovernmental organisation that runs Europe's operational weather satellites, or the European Commission through its own Earth observation programme, known as Copernicus.
It is conceivable also that international partners, such as the US and China, would be interested in lofting a constellation of satellites.

Darn Bermuda tracking station, why didn't you function. Lost of signal exactly at the point of AVUM ignition. The evidence for this is the interruption in the Yellow (actual flight path) line.
I feared for the worst for about three minutes. Luckily The signal was picked up in Canada.
And again the English broadcast translates the French massages wrongly. The callout of Bermuda not picking up the signal was translated as Bermuda picked up the signal.
Luckily all is fine.

Second burn of the AVUM. Out of the initial parking orbit into its planned circular orbit. Only a short 23 second burn required for this orbital bump into the correct lane.

Thanks for the coverage I think it's very complete. And congrats on the successful launch of Aeolus.
(Let's not ruine the joy with my opinion about the YouTube Arianespace coverage.)
I thought Earthcare was the next Earth Explorer sattelite planes for launch. Followed by Biomass and than Flex. But apparently the schedule has changed or....  :-X

Edit to add: on the EOportal FLEX launch is planed for 2022, Biomass 2021 and Earthcare in Aug. 2019. A interesting fact about Earthcare is that it contains a more advanced Lidar; ATLID. It will make vertical profiles of Aerosols and thin clouds. (Possibly it collaborates with Aeolus)

Late Edit 2: here:ESA Earth Explorers It is stated that Earthcare is planned for launch in 2021. No date for Biomass and opportunity mission Flux (Biomass compannion).

Another successful launch by Arianespace and Vega for ESA and sustainable development

August 22, 2018 – Arianespace has successfully launched the European Space Agency’s (ESA) Aeolus satellite, the first space mission designed to acquire profiles of Earth’s winds on a global scale.

The launch took place on Wednesday, August 22, 2018 at 6:20 p.m. (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana (South America).

Today’s launch was the fifth of the year for Arianespace, the first with Vega and the 12th successful launch in a row of this light launcher.

This innovative mission once again clearly demonstrates Arianespace’s commitment to sustainable development, and to guaranteeing independent access to space for Europe.

Arianespace supports sustainable development

Aeolus is the first space mission designed to measure wind profiles across the entire planet. It will deliver data and 3D dynamic maps that will help improve weather forecasting and climate research. The first wind observation satellite using laser technology, Aeolus carries a single instrument, a Doppler wind lidar called Aladin (Atmospheric LAser Doppler INstrument). This instrument will probe the atmosphere with pioneering ultraviolet laser pulses, which will enhance our understanding of tropical dynamics and processes relevant to climate variability.

Fully committed to making life better on Earth, Arianespace has already launched 65 Earth observation satellites in the framework of 46 missions. These satellites primarily are designed for meteorology, mapping and environmental monitoring (land, oceans and atmosphere). Arianespace leverages the versatility of its complete family of launch vehicles, Ariane, Soyuz and Vega, to carry out these missions for European institutions and governments, as well as in export markets.

Three more Arianespace missions for Earth observation and environmental monitoring are scheduled in 2018, using all three launchers in the family.
 
50th successful mission for ESA

Along with the successful launch of the four latest Galileo satellites by Ariane 5 on July 25, today’s launch reflects the strong collaboration between ESA and Arianespace. In fact, this mission was the 50th performed for the European Space Agency by Arianespace, as it continues to guarantee independent and reliable access to space for Europe, and enable people from around the world to benefit from Europe’s ongoing investment in space technology.

Arianespace’s next mission for ESA will be the launch of BepiColombo, a major scientific mission to explore the planet Mercury. BepiColombo is expected to lift off on an Ariane 5 in October this year.


12th successful Vega launch in a row

Today’s launch of Aeolus marks the 12th success in a row for the Vega light launcher since it was introduced at the Guiana Space Center in 2012. Based on this flawless performance, Vega has established its position as the most reliable and versatile launcher in its class. Avio, based at Colleferro in Italy, is the prime contractor for Vega, which was developed within the scope of an ESA program. Arianespace’s backlog includes nine missions for the Vega and Vega C launcher versions: one-third for European institutions and two-thirds for export customers. These nine missions comprise eight for Earth observation, as well as a grouped mission using the SSMS (Small Spacecraft Mission Service) system, which can carry up to 81 small satellites – demonstrating the launcher’s versatility and ability to respond to the dynamic small satellite market.

The development of the new-generation Vega C is continuing, with a first flight planned in 2019. Compared with the current version, Vega C will offer higher performance in terms of payload capacity (weight and volume) and greater flexibility to handle a wider range of missions (from nanosatellites to large optical and radar observation satellites), further increasing the competitiveness of Arianespace’s launch solutions.

Shortly after the announcement of the satellite’s orbital injection, Stéphane Israël, Chief Executive Officer of Arianespace, said: “With this fifth mission of the year, and the first launched by Vega, Arianespace also chalks up its 50th mission for the European Space Agency and expresses its primary vocation of ensuring autonomous and reliable access to space for Europe.

“Arianespace is all the more proud of this success because Aeolus will support sustainable development and further our understanding of climate phenomena. More than ever, space will play a critical role in the mobilization needed to safeguard our planet.

“Today’s flight also marks the 12th consecutive successful Vega launch, clearly confirming this launcher as best in its class. I would like to thank all our partners who contributed to this success: Airbus Defence and Space, which built this high-tech satellite; ESA and its member-states who are part of the Vega program; Avio, prime contractor for the Vega launcher and all of its industrial partners; CNES/CSG, our ground segment companies and all staff at the space center. Lastly, congratulations to everyone at Arianespace for this fifth launch of the year.”

Understanding the Earth’s weather: Arianespace launches Europe’s Aeolus wind-monitoring satellite
 
Arianespace marked another mission accomplished for the Earth’s sustainable development as its light-lift Vega vehicle successfully orbited Europe’s Aeolus – the first satellite designed to profile wind profiles on a global scale.

Lifting off from the Spaceport’s Vega Launch Complex at 6:20:09 p.m. local time in French Guiana – the planned precise moment of launch – Vega lofted its passenger during a flight lasting just under 55 minutes, with Aeolus placed into a Sun-synchronous orbit.

Built by Airbus Defence and Space, the satellite carries a laser Doppler wind LIDAR (Light Detection and Ranging) system called Aladin that will probe the lowermost 30 km. of the atmosphere in measuring winds around the Earth.

The LIDAR’s near-real-time observations will provide reliable wind profiles, further improving the accuracy of numerical weather and climate prediction, as well as advance the understanding of tropical dynamics and processes relevant to climate variability.

Vega’s success by the numbers

In post-launch comments from the Spaceport, Arianespace CEO Stéphane Israël congratulated this mission’s customer – the European Space Agency (ESA) – and underscored his company’s continuing contributions to space research and science at the service of such institutions.

“Ensuring reliable and independent access to space for Europe is our no. 1 mission,” he added. “It would not be possible without the long-term partnership we have with ESA.”

Aeolus marked the milestone 50th mission – and the eighth dedicated to Earth observation – performed by Arianespace for ESA. It is one of the agency’s Earth Explorer missions, which address key scientific challenges identified by the science community and demonstrate breakthrough technology in observing techniques.

Marking another milestone, Aeolus also is the 120th Airbus-produced spacecraft launched by Arianespace, with 20 more still in the company’s order book.

A track record of excellence
Designated Flight VV12, today’s mission was Vega’s 12th since entering service in 2012 (all of which have been successful), and it further demonstrated the capabilities of a light-lift vehicle that completes Arianespace’s launcher family – joining the company’s medium-lift Soyuz and heavyweight Ariane 5 in reliable side-by-side operations from the Spaceport in French Guiana. Vega is provided to Arianespace by Italy’s Avio, which is the industrial prime contractor.

The 12 successful missions performed to date by Vega were for both institutional customers and commercial export customers, confirming the launcher’s operational capabilities as well as its adaptability.

Flight VV12 was Arianespace’s fifth mission in 2018, and the company’s first this year using Vega. Next up in the company’s manifest is the milestone 100th launch of a workhorse Ariane 5, which will orbit the Horizons 3e and Azerspace-2/Intelsat-38 commercial telecommunications satellites in September.

Airbus-built Aeolus satellite to map Earth’s wind in real-time

Kourou, 22/08/2018 - Aeolus, the European Space Agency’s wind sensing satellite, built by Airbus, has been successfully launched from Kourou, French Guiana. The satellite will now undergo a series of tests in its operational orbit at 320km before beginning operations.

Built by Airbus, Aeolus is the first satellite capable of performing global wind-component-profile observation on a daily basis in near real-time.

The 1.4-tonne spacecraft features a LIDAR (Light Detection And Ranging) instrument called Aladin, which uses the Doppler effect to determine the wind speed at varying altitudes.

Aladin fires a powerful ultraviolet laser pulse down through the atmosphere and collects backscattered light, using a large 1.5m diameter telescope, which is then analysed on-board by highly sensitive receivers to determine the Doppler shift of the signal from layers at different heights in the atmosphere.

The data from Aeolus will provide reliable wind-profile data on a global scale and is needed by meteorologists to further improve the accuracy of weather forecasts and by climatologists to better understand the global dynamics of Earth’s atmosphere.

Nicolas Chamussy, Head of Space Systems at Airbus said: “Aeolus is another first for Airbus, delivering a revolutionary Earth observation satellite that will give wind profile data in near real time, improving weather forecasting and helping to bring the benefits of space down to every citizen on Earth.”

Aeolus will orbit the Earth 15 times a day with data delivery to users within 120 minutes of the oldest measurement in each orbit. The orbit repeat cycle is 7 days (every 111 orbits) and the spacecraft will have a lifetime of three years.

ESA’s Earth Explorer Aeolus satellite has been launched into polar orbit on a Vega rocket. Using revolutionary laser technology, Aeolus 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.

Carrying the 1360 kg Aeolus satellite, the Vega rocket lifted off from Europe’s Spaceport in Kourou, French Guiana, at 21:20 GMT (23:20 CEST, 18:20 local time) on 22 August.

Some 55 minutes later, Vega’s upper stage delivered Aeolus into orbit and contact was established through the Troll ground station in Antarctica at 00:30 CEST on 23 August.

Named after Aeolus, who in Greek mythology was appointed ‘keeper of the winds’ by the Gods, this novel mission is the fifth in the family of ESA’s Earth Explorers, which address the most urgent Earth-science questions of our time.

“Aeolus epitomises the essence of an Earth Explorer. It will fill a gap in our knowledge of how the planet functions and demonstrate how cutting-edge technology can be used in space,” said Jan Wörner, ESA Director General.

ESA’s Director of Earth Observation Programmes, Josef Aschbacher, added, “Aeolus carries the first instrument of its kind and uses a completely new approach to measuring the wind from space. Such pioneering technology has meant that it has been a demanding mission to develop, but thanks to all the teams involved we are thrilled that this extraordinary satellite is now in orbit.

“We look forward to it living up to expectations!”

Highlighted by the World Meteorological Organization, the lack of direct global wind measurements is one of the major deficits in the Global Observing System.

By filling this gap, Aeolus will give scientists the information they need to understand how wind, pressure, temperature and humidity are interlinked.

This new mission will provide insight into how the wind influences the exchange of heat and moisture between Earth’s surface and the atmosphere – important aspects for understanding climate change.

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.

While Aeolus is set to advance science, it will also benefit society. Although weather forecasts have advanced considerably in recent years, Aeolus will provide global wind profiles to improve the accuracy even further. In addition, its data will be used in air-quality models to improve forecasts of dust and other airborne particles that affect public health.

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.

First light from Aeolus

Following the launch of Aeolus on 22 August, this extraordinary satellite is not only emitting pulses of ultraviolet light from its laser, but has also measured light backscattered from air molecules and cloud tops. The measurements show a full orbit around Earth, from the Arctic to the Antarctic, and back. For calibration purposes the signal backscattered from Earth’s surface is used, which is also seen in these results.
