A team of astronauts, engineers and geologists is traveling to Spain's Canary Islands, one of Europe's volcanic hot spots, to learn how to best explore the Moon and Mars during ESA's Pangaea geological training course.

This edition's participants are ESA astronaut Andreas Mogensen, ESA engineer Robin Eccleston and NASA astronaut Kathleen Rubins, who is part of the group of NASA astronauts selected to potentially land on the Moon for the Artemis missions, where research on lunar geology will be crucial.

Volcanism is not exclusive to Earth. Our Moon had extensive volcanic activity until less than two billion years ago. Mars is currently a cold, dry desert, but in the past most of the planet's surface was shaped by water and volcanoes in a very Earth-like fashion. The Red Planet has the largest known volcano in our planetary neighborhood—the 22 km high Mount Olympus.

The basaltic lava flows in Lanzarote Island, located to the far east of the Canary Islands, resemble vast plains on the lunar maria and volcanoes are similar to those in some regions of Mars. This will help Pangaea's participants to prepare for the future expeditions to Mars and the Moon.

Pangaea—named after the ancient supercontinent—prepares the astronauts for expeditions to other planets. Trainees acquire skills and knowledge both in the field and in the classroom tailored towards the needs of future planetary explorers.

Participants analyze the chemistry and mineralogy of the soil, choose their own exploration routes and rely on technology in constant communication with the science and training teams.

"We instruct astronauts on reading and describing landscapes and running efficient sampling taking into account the environment around them, such as dust and volcanic rocks," says Francesco Sauro, Pangaea's technical course director. "From selecting a landing site to describing samples with the right scientific vocabulary, this is the basic geological education they will need in future field trips for lunar missions," adds the geologist.

A giant balloon that became a popular landmark over the skies of Paris during the 2024 Olympics is set to rise again, with organizers hoping it will once again attract crowds of tourists.

During the Games, the Olympic cauldron tethered to a balloon flew above the Tuileries garden at sunset every day, with thousands flocking to see the seven-meter (23 feet) wide ring of electric fire, AFP said.

Last summer's version "had been thought up to last for the length of the Olympic and Paralympic Games," said Mathieu Lehanneur, the designer of the cauldron.

After President Emmanuel Macron "decided to bring it back, all of the technical aspects needed to be reviewed", he told AFP on Thursday.

Lehanneur said he was "very moved" that the Olympic balloon was making a comeback.

"The worst thing would have been for this memory to become a sitting relic that couldn't fly anymore," he said.

The new cauldron will take to the skies on Saturday evening during France's annual street music festival, the Fete de la Musique.

The balloon will rise into the air every evening until September 14 -- a summer tradition set to return every year until the 2028 Los Angeles Games.

"For its revival, we needed to make sure it changed as little as possible and that everything that did change was not visible," said Lehanneur.

With a decarbonated fire patented by French energy giant EDF, the upgraded balloon follows "the same technical principles" as its previous version, said director of innovation at EDF Julien Villeret.

The improved attraction "will last ten times longer" and be able to function for "300 days instead of 30", according to Villeret.

The creators of the balloon also reinforced the light-and-mist system that "makes the flames dance", he said.

Under the cauldron, a machine room hides cables, a compressor and a hydro-electric winch.

That system will "hold back the helium balloon when it rises and pull it down during descent", said Jerome Giacomoni, president of the Aerophile group that constructed the balloon.

"Filled with 6,200 m3 of helium that is lighter than air," the Olympic balloon "will be able to lift around three tons" of cauldron, cables and attached parts, he said.

The Tuileries garden is where French inventor Jacques Charles took flight in his first gas balloon on December 1, 1783, Giacomoni added.

He followed in the footsteps of the famed Montgolfier brothers, who had just nine days earlier elsewhere in Paris managed to launch a similar balloon into the sky with humans onboard.
