Iberia to Fly Researchers Above the Clouds for Spain's First Total Solar Eclipse in Over a Century

On August 12, Spain will experience its first total solar eclipse since 1912, and Iberia is marking the occasion with a specially designed flight built not for tourists, but for scientists.

A Mission Named for Copernicus

The Spanish flag carrier will operate a one-off charter using an Airbus A321XLR, one of the newest additions to its long-haul narrowbody fleet. The aircraft will depart Madrid-Barajas Airport in the early evening, with reported takeoff times clustering around 6:45 to 7:13 p.m. local time, and follow a flight path deliberately plotted over Palencia province in north-central Spain to track the Moon's shadow as closely as possible during the eclipse's period of totality, expected to peak around 8:30 p.m. CEST.

The flight carries the number IB1473, a deliberate nod to 1473, the birth year of the Renaissance-era astronomer Nicolaus Copernicus. It's a fitting touch for a mission built entirely around astronomical observation: rather than paying passengers, the cabin will be filled with a team of researchers from the Shelios project, a scientific and educational initiative led by astronomer Miquel Serra-Ricart, formerly director of the Astrophysics Institute of the Canary Islands and currently affiliated with the institute as well as Light Bridges.

A Flying Laboratory

Flying at roughly 10,000 meters, well above the cloud layer and most atmospheric interference, gives the Shelios team a vantage point that's difficult to replicate from the ground. Their primary goal is to study the solar corona, the sun's faint outer atmosphere that becomes visible to the naked eye only during a total eclipse. 

Researchers plan to take measurements of the corona's structure and dynamics, and the Canary Islands Institute of Astrophysics has reportedly already run simulations on its supercomputer in La Palma to anticipate what the corona might look like over Palencia and plan their observations accordingly. The mission will also give the team a chance to observe the relative positions of Venus, Mercury, and other stars that briefly become visible as the sky darkens.

The flight has a notable connection to its own science team: co-pilot Javier Meana Fernández has a background in astrophysics in addition to his aviation training, a detail airline coverage has highlighted as underscoring the mission's scientific character. The aircraft is reportedly set to be commanded by Javier Lopera Alcalá.

Watching From the Ground, via Starlink

While the flight itself isn't open to the public, Iberia intends to bring the experience to a much wider audience online. The airline will stream live footage from multiple onboard cameras, reportedly including a cockpit-mounted GoPro, via its social media channels throughout the flight. 

That's possible because the A321XLR assigned to the mission is among the first aircraft in Iberia's fleet fitted with Starlink satellite internet connectivity, supplied by SpaceX, which the airline began rolling out on flights earlier this year. The broadcast is expected to begin shortly after takeoff and continue through totality until the aircraft begins its descent.

Aviation Meets Astronomy

The mission reflects a broader, if niche, trend of commercial aviation being pressed into service for scientific observation. Eclipse-chasing flights aren't new, but pairing one with a research program, a scientifically credentialed flight crew, and live-streamed satellite connectivity gives this one an unusually integrated setup. 

For Iberia, it also doubles as a showcase for both its newest aircraft type and its expanding in-flight connectivity technology.

What Spain Will See From the Ground

On the ground, the eclipse will be visible across Spain to varying degrees. Cities including Bilbao, Zaragoza, and Valencia are expected to fall within the path of totality and experience complete darkness for a short window, while Madrid and Barcelona are set to see a partial eclipse of around 99%. 

For most Spaniards, that will mean watching the sky darken from beaches, parks, and city viewpoints rather than from 35,000 feet. But for the Shelios researchers aboard IB1473, and for anyone tuning in online, the eclipse will be visible from a seat above the weather, on a flight timed to the century-old rarity of a total solar eclipse crossing the Iberian Peninsula.
