With the climate emergency so acute that people are tempted to put their head in the sand, SolarStratos is approaching 2024 more determined than ever. Our mission this year is to set a record for the highest electric solar-powered flight in history. Everything is in place, both from a technological and administrative point of view, and with our permit to fly (PTF) secured, the whole team is looking forward to taking off again. Stay tuned, we are excited to share some new and memorable moments with you as the year unfolds. Welcome aboard for the next flight!

The Copernicus report is chilling
Copernicus confirmed on the 8 January that 2023 was the hottest year on record. ‘For at least 100,000 years’ according to the Observatory. The report also signalled a global temperature of 1.48°C more than average putting our world on the brink of the maximum + 1.5°C threshold envisaged in the Paris agreement. The ocean is suffering from record temperatures. And the highest concentration of greenhouse gases was recorded in the atmosphere. These are all chilling facts that make the SolarStratos mission all the more compelling. Living and flying on solar power means that people can embrace a sustainable low-carbon future today. Let’s act.
Press review 2023: We make solar energy shine
Beyond the challenge of flying to the stratosphere, SolarStratos aims to be a communications platform to raise awareness and promote solar energy. Our 2023 press review shows that the adventure is having an impact. By sharing the successes, records, and pitfalls, we are spreading our sustainability message far and wide. Through five press releases, 12 newsletters, hundreds of social media posts with a reach of up to 250,000 people, plus several dozen videos (347,000 views for the 2023 highlights on Facebook) and reels achieving up to 4.2 million views (16.5 million for 7 short reels), plus thousands of likes and comments of encouragement – we can continue to dream! Thank you for following us, thank you to our partners and sponsors for making this adventure possible, and to the world’s media for working with us to spread the word about a possible, sustainable future.
Completing the team
SolarStratos gathers around its founder Raphaël Domjan and its CEO Roland Loos a whole range of talented team members with skills that span technology, logistics, administration, events, communications, filmmaking, and more. At the dawn of a new year that promises plenty of action, we are recruiting to better face the challenges ahead, and we very much look forward to introducing you to our new team members.
2023 was an eventful year for SolarStratos – the solar electric aircraft spread the word about the potential for solar energy far and wide. Some of the highlights include Alyssa Carson’s visit, EBACE in Geneva where the mission was present with the 3 axis flight simulator, and the pioneer’s evening at the Paris Air Show. Not forgetting Prince Albert II of Monaco’s visit to Payerne after the summer break for another electric flight with Raphaël Domjan! HB-SXA has been further optimised this year (specifically the batteries and propellor) and is ready for take-off in 2024 to set the altitude record for a manned solar electric aircraft. We can’t wait! But for now, the whole team would like to wish you Happy Holidays!
Our 2023 highlights video is here!
The festive season is also a time for taking stock. And for SolarStratos that comes in the shape of a highlights video. Written by Stéphane Chopard – the filmmaker that is documenting this crazy adventure – the ‘2023 highlights’ is ready for you. You’ll see, it has been an exciting year for SolarStratos – the mission has dramatically demonstrated just how much solar energy can contribute to the transition to a low-carbon world.
And the title of best influencer goes to…
Alyssa Carson!
You’ll remember that she visited us at our home base in Payerne at the beginning of 2023. She tried the new flight simulator and flew in the electric plane over Swiss countryside blanketed in snow. Well… Alyssa Carson has just won ‘best science influencer in the USA’! The whole SolarStratos team congratulates @nasablueberry for this wonderful recognition of her commitment. Relive her visit to Switzerland here.
With our best wishes!
Roland Loos, Raphaël Domjan and the whole SolarStratos mission team would like to thank you for being part of and for following this incredible solar adventure. Thanks also to all our sponsors, partners and supporters who make this project possible. All our team wish you a Merry Christmas and a New Year filled with positive energy – solar energy! We look forward to reconnecting in January – it’s going to be a great year!
The sun is still shining brightly – a fact that warms the hearts of those – including the SolarStratos mission – who advocate for the intensive use of solar energy to ensure a low-carbon future for the planet. This need for change is heavily underlined by the new 2023 temperature records. The coming year will be crucial for the SolarStratos project. Achieving an altitude record for a manned solar-electric aircraft with HB-SXA is not only the final step before stratospheric flight, but it will send out a symbolic message that yes, we can continue to dream. To fly. Ever higher. And above all, without harming the planet.
Records that are cause for alarm
In Switzerland, September 2023 was the hottest since measurements began in 1864. June, July and August were the hottest months on earth. Temperatures in Switzerland in October also exceeded the average by 3.1°C, less extreme, but still notable – the average was 9.8°C compared to 10.4°C in October 2022. These results have propelled the planet to the top of the IPCC’s forecast range and the 1.5°C maximum warming limit set by the Paris Agreement is about to be exceeded. It’s time to go solar. Resolutely and urgently.
Senegalese sun
Roland Loos and Raphaël Domjan, respectively SolarStratos CEO and pilot-founder, have been active on other fronts. In November, they returned to Senegal on behalf of the PlanetSolar Foundation to check the Saint Louis solar power plant that opened in 2019 and – alongside the local authorities – to inaugurate the CIFOP vocational training centre for solar installers, a vocational school in Mboro. This mission was organised by Roland Loos – who is very committed to Senegal – in partnership with Jean-François Affolter. Bravo Messieurs.
Monegasque sun
Solar energy is not only our future, but the future of aviation. This was the message that Raphaël Domjan conveyed in Monaco this month at the World Connect by APG event. Monaco Matin and Nice Matin marked the occasion with comprehensive coverage of the ambitious PlanetSolar mission and Prince Albert II of Monaco’s support for the project, including the sovereign’s visit to us last September. Positive, energising feedback!

To track the HB-SXA flights as closely as possible
As you know, on the www.solarstratos.com website, you can experience every moment of HB-SXA’s flights online via the virtual cockpit. Some seventy to date! The latest enhancement to our solar-electric aircraft involves telemetry. The new, more precise system will also enable us to stream not just one, but two of the Go-Pro cameras on board!
“From now on, we’ll be using UHF waves rather than 4G giving us much greater range, estimated up to 20km,” explained Jonathan Amez-Droz, an embedded systems engineer trained at HEIG-Vaud in Yverdon-les-Bains, Switzerland, with whom the system was developed.
A new antenna will be fitted to the underside of the aircraft, along with new electronics to manage communications. The whole team is looking forward to testing these new features on their next flight!

A SOL-AIR evening with highflyers
Our SOL-AIR event on Friday 6 October at the base in Payerne brought together a group of pioneering minds for a discussion on environmental challenges. Invited by Raphaël Domjan, Professor Christophe Baillif, Director of the Sustainable Energy Centre at CSEM, presented the latest innovative solutions to our partners, friends, explorers and committed politicians. His exceptional contribution impressed the high-profile audience, including politicians committed to a sustainable future, such as François Pointet and Jacqueline de Quattro. Jacqueline de Quattro was incidentally re-elected in the federal elections on 22 October: Bravo!
“An ode to exploration, innovation and collaboration”
There are evenings when the stars and the sun align to radiate innovation and the spirit of adventure and one such took place on Tuesday 3 October, when our partner Marti Arc Jura SA, its customers, partners, friends, and employees joined us in Payerne for a celebration. The exceptional event was led by company director Thierry Linder and Raphaël Domjan, whose presentation showed how to push back the boundaries of what is possible. The words of Marti Arc Jura SA on LinkedIn (https://urlz.fr/o8mf) spoke straight to our hearts: “This evening will remain engraved in our memories as an ode to exploration, innovation and collaboration”.
Thank you!

This summer of 2023 confirms it if confirmation were needed. By overexploiting fossil fuels, when solar energy is available on a (photovoltaic) panel, humanity is creating a pressure cooker that is driving up temperatures. With all the disruption this rapid warming is causing. With every piece of glacier that disappears, every flood, every windstorm that wreaks havoc, every piece of land that becomes desert, the SolarStratos mission takes on even more meaning. Demonstrating, with the enthusiasm of adventure and with the passion of a pioneering spirit, that the challenge of flying to the stratosphere in an electric and solar-powered aircraft is possible, allows us to dream in spite of everything. Our message is as clear as it is solar: to live our dreams in the future, we need to save our future now.
Un été canisolaire à records
The statistics promise to reach new records in 2023 for sunshine. This summer has seen some alarming firsts. On the night of 20 to 21 August, the zero-degree isotherm reached an altitude of 5,298 metres! It only took a year for the previous historic peak of 5,184 metres on 25 July 2022 to be exceeded. As for the heat dome, it sent the ground thermometer into a frenzy: 39.3°C in Geneva, over 41°C in Lyon. And almost 44°C in the Ardèche. Ah, if only mankind could tap into this inexhaustible source of energy…
Géo : Raphaël Domjan
parmi ses explorateurs
“Today’s explorers have swapped the desire to surpass themselves for a quest for meaning. And they see their expeditions only in terms of commitment”. In its latest special issue, GÉO Magazine chose Raphaël Domjan as one of its selection of explorers of this new type, who “became an expert in renewable energies and solar energy because he wanted to fight climate change”. Thank you to GÉO for relaying this message. And thank you to all the explorers who are shouting out that the planet must be allowed to keep on dreaming!
Exhilarating, but also moving and powerful! Taking part in the 54th International Paris Air Show last week in Le Bourget will go down as an important moment in the SolarStratos adventure.
Having Europe and Switzerland’s electric and solar-powered aircraft present at the most important aeronautical event in the world showcased the SolarStratos mission and conveyed its message to the giants of aviation.
A grain of sand to show this gigantic economy (India for example signed a contract for 500 Airbus!) the immense potential of electric power for a low-carbon future for aviation and the planet.
In addition to President Emmanuel Macron of France and 3,000 journalists, the International Paris Air Show attracted 400,000 visitors! Here are some of the highlights experienced by the SolarStratos team and its partners – Longines, Présence Suisse, the Canton of Neuchâtel, InnoVaud, and CSEM – in the 600 m² tent on the tarmac at Le Bourget.
Pioneers’ Evening:
back to the future
Being a pioneer today goes hand in hand with great respect for those of yesteryear. Our Pioneers’ Evening at the SolarStratos stand attracted a prestigious group, including extreme sportswoman Géraldine Fasnacht, explorer Bertrand Picard, solar navigator and pilot Raphaël Dinelli, astronaut Jean-François Clervoy, pilot Gérard Thevenot, navigator and mountaineer Eric Loizeau, and pilots Jean-Baptiste Loiselets, André Borschberg and Hervé de Saint Exupéry. Thank you to all those who honoured us with your presence.
Thank you, Mr “How Does It Work?”!
He arrived with a spring in his step, barely out of breath, ahead of his young cameraman. Welcoming Michel Chevalet, visiting the SolarStratos stand as a reporter for the Canal + channels, is no small thing. At 83, the French science journalist who inspired generations of television viewers with his legendary question “How does it work?” remains as passionate as ever about his subject. SolarStratos – or “solar albatross” as he calls it – excites him, and he salutes Raphaël Domjan’s passion. “Going up there, where you can see the stars and the shape of Earth below you, I did it with Concorde back in the day,” he said. “To do it with solar energy is edifying.”
At the end of the interview, the two enthusiasts thanked one other. And then they hugged. A symbolic moment that sent shivers down the spine of more than one onlooker!
A new lease of life in our media impact
Even before take-off from Le Bourget, France 2 set the world alight with magnificent images of HB-SXA in flight, filmed at Payerne. On the opening day, RTS broadcast a report in its 19:30 programme. Alain Rebetez wrote a hard-hitting full-page article in 24 Heures. Plus, we had coverage on France Inter, Europe 1, etc. At times, the SolarStratos stand felt like a press centre!
Raphaël Domjan, who is very committed to the objective of sharing the mission with the younger generation, was delighted with the coverage – two six-page special issues – published by the children’s magazines L’Actu and Mon Quotidien. A nice boost in media impact!
HB-SXA simulator:
the dream lives on!
It is instantly recognisable. Our three-axis flight simulator, with its triple screen arrangement, is always eye-catching. And it was the envy of young and old, even among the panoply of exhibits and experiences on offer at the Paris Air Show. Sadly not everyone had the opportunity to take the controls and fly over Le Bourget during the two daily sessions on offer, but the dream lives on!
Thank you, Le Bourget!
The gigantic scale of this world aviation showcase, its ultra-secure entrances and the constant stream of professionals and visitors, did not rule out some fun and friendly moments. Even on the social networks! The Show’s communications team relayed a picture of the SolarStratos team jumping with joy on the opening morning. We thanked Le Bourget and they thanked us back!
Don’t miss the SolarSratos aftermovie at Le Bourget, here: https://vu.fr/SXCS
The sun shone on the European Business Aviation Convention & Exhibition last week when our whole team put our mission to promote sustainable aviation in the spotlight at the Geneva event. As the first guest speaker at the opening ceremony Raphaël Domjan set the tone, calling on the aviation industry to set an example: “If this sector, where decarbonisation is the most difficult, takes up the challenge, the message would be fantastic, no sector would be able to avoid it.”
But above all, SolarStratos shared the dream at the event, with the HB-SXA simulator on hand to give some lucky candidates the opportunity to experience the thrill of flying solar. Among them, 17-year-old Mack Rutherford – the youngest pilot to complete a solo around the world flight – and Erik Lindbergh, the grandson of Charles Lindbergh who completed the first solo transatlantic flight in 1927. The experience provided a ray of sunshine for the young pilots and was a great warm-up for the Paris Air Show which will take place at Le Bourget from 19-25 June where SolarStratos will be on site — and hopefully in the air too!

Massimo Fiorin flies over
Payerne – from Geneva!
“Incredible. Fantastic to be able to fly over the Payerne runway that I see every day from my office!” (editor’s note: this was said from the SolarStratos stand in Palexpo). Still at the controls of the simulator, Massimo Fiorin, Managing Director of swiss aeropole, expressed his enthusiasm: “SolarStratos gives those involved in aviation the confidence to tackle the challenges of the energy transition and find solutions, while at the same time attracting young people to careers in aeronautics. We can enjoy exciting, adrenalin-fuelled experiences. Like reaching the edge of space in a solar-powered aircraft that produces absolutely no pollution!”
Giovanni Russo:
“Flying like this is a real dream”
Giovanni Russo, Head of Operations at Geneva Airport, also enjoyed his experience on the flight simulator. “Excellent. Unheard of. A great feeling. Very smooth, it reminded me of a motor glider. It proves that we can switch from traditional fuel to solar and electric energy. It’s a benchmark for the future, for the decarbonisation of our industry and the legitimacy to continue to exist in this world. Having flown mainly internal combustion engines and motor gliders, to be able to fly independently and sustainably is a real dream!”
And the dream is already a reality, as Juergen Wiese, Chairman of the EBAA, highlighted: “Look at my smile! If you only dream, you’re just a dreamer. What you are doing with SolarStratos – already flying – is reality. You’re taking us forward and proving that aviation can reinvent itself!”

Live on EBACE TV
Of the many contributions made by our pilot and founder at EBACE 2023, you can watch the interview that he gave a couple of hours after his speech at the opening ceremony here on EBACE TV: https://youtu.be/GLuO83SsvuA
On Wednesday, Raphaël gave a talk at the Sustainability Theatre entitled ‘Take a Trip to the Stratosphere!’. Take a trip to the stratosphere powered by the sun. A reminder to the business aviation sector of its commitment, in 2009, to reduce its carbon emissions by 50% by 2050 in the face of climate change (BACCC).
Genesis and its all-electric range
teams up with SolarStratos
Genesis is joining the SolarStratos adventure as official automotive partner with its range of all-electric vehicles. Raphaël Domjan has the pleasure of driving a Genesis V60: “My first all-electric car. It’s very attractive, with impressive torque and power, while being silent and CO2 emission-free,” he said.
Piergiorgio Cecco, Head of Regional Operations at Genesis Motor Switzerland, said: “This collaboration represents a major step forward in our brand’s vision of a sustainable future.”

On the evening of Monday 17 April the trailer carrying HB-SXA arrived in Payerne from our partner Elektra Solar in Germany.. The atmosphere around its arrival resembled that of a spy movie, the airplane passed through the security gate in the middle of the night and soundlessly crossed the tarmac before slipping into the SolarStratos home base which was lit up in welcome. In the hours that followed its arrival the plane was reunited with its wings and various other components, and emerged just in time for the partners’ evening with a new face – literally. HB-SXA is now ready to fly – without emissions – towards the challenges and records planned for 2023. Take off will happen as soon as all the technical modifications are approved by the Federal Office of Civil Aviation (FOCA) and a new permit to fly is issued.
A new nose
Have you noticed the change? The new engine, its new larger propellor with improved variable pitch, and the new battery arrangement have changed the front of HB-SXA quite a bit. The plane has a new nose, and above all a new smile as the increase from six to eight batteries for the next altitude record require an increase in air supply for cooling purposes. Hence the larger opening at the front of the fuselage in the shape of a fish’s mouth. A new and friendlier look!
A partners’ evening and a boost
The SolarStratos partners were invited to the home base in Payerne on Wednesday 19 April for the much-anticipated partners’ evening. The gathering was an opportunity to present the latest technical modifications that will facilitate a first attempt at an altitude record this summer, plus the forthcoming events such as the European Business Aviation Convention & Exhibition (EBACE) in Geneva in May and the Paris Air Show in June. The plane’s new face did not go unnoticed!
During the evening guests were invited to express in a few words what they think the strength of the project is. Their answers, which gave the whole team a boost, can be found online on LinkedIn: here and here and Facebook.
Support for the climate bill
During the partners’ evening, Raphaël Domjan informed the sponsors of SolarStratos’ support for the Climate Law that will be put to a popular vote on 18 June. “An electric and solar aircraft project, which aims to be a platform for promoting solar energy and sustainability, must support Switzerland’s ambition to achieve climate neutrality by 2050,” he said.
Paris Air Show:
scouting in Le Bourget
The International Paris Air Show is a mega-event. And as you know, SolarStratos has the opportunity to feature among the giants of aeronautics with its small electric and solar aircraft from the 19 to 25 June. There are even plans for an exhibition flight over the ‘City of Light’, weather conditions permitting. The event which creates a city of 20,000 inhabitants for over 300,000 visitors and 3,000 journalists, requires a great deal of preparation. On 17 April, our Marketing and Events Manager, Jennifer Uldry, travelled to Paris for the exhibitors’ day along with Coralie Jugan, our press officer in France. We aim to shine and look forward to welcoming you in June. But before that, don’t miss SolarStratos at the European Business Aviation Convention & Exhibition at Geneva-Palexpo from 23 to 25 May – come and try our simulator! We look forward to welcoming you onboard.
Watch the video released this weekend to relive the incredible days spent with Alyssa Carson discovering Solarstratos in Switzerland.
At 21, Alyssa is an astrobiology student, speaker, businesswoman and celebrity influencer with over 501,000 followers on Instagram and 204,000 on Facebook, all while training to become a professional astronaut.
She shares her journey and experience while delivering a powerful message of hope for a greener future in the sky.
Thank you, Alyssa.
As 2022 draws to a close, although the climate situation is serious, it is a time to celebrate. The oppressive shadow of global warming and the energy crisis make the SolarStratos adventure all the more legitimate. The challenge of flying ever higher in an electric and solar aircraft makes the SolarStratos project a powerful promotional platform and a vehicle for change. The mission aspires to playing a decisive and driving role in the necessary shift to solar energy. Because after all, the greatest gift in the world is the sun, its infinite energy available to everyone. We can’t compete with such a gift, but we can promote and share it with a maximum amount of people! Our last newsletter of the year comes with a few gifts to brighten up these end-of-year celebrations, and the entire SolarStratos team wishes you a radiant festive season!
The challenges of reaching higher in 2023
You lived our adventures alongside us, so you will recall some of our 2022 highlights, including a record setting world premiere wingsuit jump from an electric and solar powered aircraft in June in Verbier! This was preceded by a first inter-city flight in May between Payerne and La Chaux-de-Fonds, and of course the Ground Vibration Test conducted by the Office National d’Etudes et de Recherches Aérospatiales (the French national aerospace research centre), a SolarStratos partner since 2020. In total, we conducted 22 new flights, notching up 14 hours and 18 minutes in the air. And every outing allowed us to learn new lessons and to answer technical questions. Batteries, motor, the flutter effect, the variable pitch propellor – mastering each element is a challenge of its own. “Our challenge in 2023 will be among other things, to identify the best engine and battery adjustments to fly even better,” said Roland Loos, CEO of the mission. And above all, to fly higher. Ever higher. With you! And to demonstrate the potential of solar energy.
When a team outing gives you wings!
The end-of-year SolarStratos team outing brought 2022 to a fitting close with the whole team experiencing the magic of flying, like a plane, but without wings! For their latest adventure, the team headed to Valais to the Realfly (https://realfly.ch/) free-fall simulator in Sion. Courtesy of the SolarStratos partner, team members got to experience the breath-taking sensation of hovering in the air in a flight chamber that was 4.35m in diameter and 14m high! You only have to take a look at the faces featured in the photos to see that this adventure was mind-blowing! Experiencing Icarus’ dream was truly amazing, and the memory is still fresh in our minds!
Some videos for under the Christmas tree!
If you like our videos, you can find three more under the Christmas tree in 2022! You’ve already seen the ‘team’s wishes for 2023’ video on our channels, but don’t miss the ‘2022 highlights’ by our videographer Stephane Chopard who has captured the high moments, the behind the scenes, and the emotions of the SolarStratos adventure. And finally, to set the scene for 2023, our partner Up To You has produced a ‘2022 epic moments’ video with their signature tempo! Enjoy!
Some gifts!
If you’re looking for some last-minute gift ideas, you are in luck! We have t-shirts, puffers, polo shirts, caps, pens, key rings, and Swiss army knives, all in SolarStratos colours with the mission logo. Take a look online at www.solarstratos.importexa.com. There’s plenty to choose from!
Paris Match: what an opportunity to raise awareness!
Among the clippings this year about our mission for a solar-powered world, several really stand out: Paris Match did a six-page portrait on Raphaël Domjan within their ‘Les héros de la planète’ (Heroes of our planet) series. You can watch the video that featured alongside the report here. Les Echos also featured a major report, to read it please click here. We extend our sincere thanks to the media, they play an important role in helping SolarStratos to fulfil its mission of promoting solar energy.
Our Christmas story: Bastien’s dream
“My children saw the solar airplane on 15 May in La Chaux-de-Fonds, and my eldest son completely fell under its spell. He was so disap pointed when he was told that SolarStratos was going home to Payerne! Since then, every time that he sees a plane, he asks me whether it’s the one that flies with the sun. I explain to him that if it is making a noise, then it cannot be the one.” Sheeba Ramseier’s story is symbolic of what a project like SolarStratos can convey, of the dreams of clean mobility and sustainability that it shares, even with the very youngest. And since it is Christmas, and to ensure that this tale has a happy ending, HB-SXZ dropped off a special package for Bastien to go under this Neuchâtel family’s Christmas tree.
