NASA's 2026 Total Solar Eclipse Plan: Jets, Balloons, and Global Science 2026

NASA is preparing an ambitious plan for the total solar eclipse on August 12, using a high-speed jet and dozens of balloons to study the Sun's corona and Earth's atmosphere. Although the path of totality will not cross the United States, the space agency is sending researchers to Iceland and Spain to capture valuable data during the brief event.

Why the 2026 Eclipse Matters for Science

The total solar eclipse offers a rare opportunity to observe the Sun's corona, the outer atmosphere that is normally hidden by the Sun's brightness. During totality, the Moon blocks the Sun's disk, revealing the corona for a few minutes. Scientists want to study this region because it is where solar wind originates and where space weather events that can affect Earth begin.

This eclipse is particularly significant because the path of totality passes over Iceland and Spain, giving researchers in those countries a chance to conduct ground-based observations. NASA is coordinating with international teams to maximize the scientific return from the event.

Chasing the Shadow with a Jet

NASA will deploy a research aircraft to fly at 740 kilometers per hour along the path of the Moon's shadow. By positioning the plane strategically, scientists can extend their view of totality to nearly three minutes, compared to just over two minutes from the ground in Iceland. This extra time allows for more detailed observations of the corona.

The idea of using aircraft to prolong eclipse observations is not new. In 1973, a team of British and French scientists used a Concorde supersonic jet to chase an eclipse, achieving over an hour of totality. Modern jets are slower, but they still provide a valuable platform for instruments that need to be above most of Earth's atmosphere.

Balloon Launch Campaign in Iceland and Spain

In addition to the jet, NASA and its partners will launch 80 weather balloons from Iceland and 6 from Spain. These balloons will carry small payloads to measure temperature, pressure, and wind in the stratosphere during the eclipse. The data will help scientists understand how the sudden cooling caused by the Moon's shadow affects atmospheric dynamics.

Weather balloons are relatively inexpensive and can be launched in large numbers, providing a broad snapshot of atmospheric conditions. The 80 balloons from Iceland will be released from multiple sites, creating a network of observations that can be compared with ground-based and satellite data.

What Scientists Hope to Learn

The primary goal is to study the solar corona in unprecedented detail. The corona is millions of degrees hotter than the Sun's surface, and scientists still do not fully understand how it is heated. By observing the corona from a moving aircraft and from the ground, researchers can obtain complementary data that may shed light on this mystery.

Another focus is the effect of the eclipse on Earth's atmosphere. The sudden drop in solar radiation during totality can trigger gravity waves and changes in the ionosphere. The balloon measurements will help quantify these effects and improve atmospheric models.

• NASA will use a jet to extend totality to nearly 3 minutes.
• 80 balloons will be launched from Iceland and 6 from Spain.
• The mission aims to study the solar corona and atmospheric response.
• International collaboration is key to the success of the campaign.
• Data will improve understanding of space weather and atmospheric dynamics.

Comparison of Eclipse Observation Methods

The combination of these methods will provide a comprehensive dataset that would be impossible to obtain from a single platform. The jet offers the longest view of totality, while balloons provide wide coverage of atmospheric parameters.

What to Watch Next

After the eclipse, researchers will analyze the data over the coming months. The results are expected to be presented at scientific conferences and published in peer-reviewed journals. The lessons learned will also inform planning for future eclipses, including those visible from the United States in the coming decades.
