APOD: 2026 August 13 – Total Solar Eclipse Over Spain

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Total Solar Eclipse Over Spain

Explanation: On August 12th, 2026, the Moon totally eclipsed the Sun and cast its shadow across Siberia, Greenland, Iceland, Spain, and Portugal. Today’s image features two total solar eclipses viewed from Zaragoza, Spain, one over the Cathedral-Basilica of Our Lady of the Pillar and the other reflecting in the Ebro River. For a few moments, Spain saw its first major total solar eclipse since 1905. Those witnessing totality may experience a chill in the air, the quieting of birds, the confused chirps of insects, and the shared awe of many. It’s the corona’s time to shine as the Sun’s bright disk is blocked by the Moon. Among other reasons to study eclipses, they help scientists understand why the corona is millions of degrees hotter than the Sun’s surface. Enthusiastic citizens can contribute to these studies by recording how wildlife responds, imaging the corona, and monitoring air temperature and clouds.

NASA Data Helps Commercial Space Plan Living Off Our Moon 

The barren lunar landscape has some important resources, such as water and minerals like iron and titanium, but extracting and processing them will require special equipment. Where those resources can be found will dictate where to land and how to mine them. To help with that, Lunar Station Corp. is using a wealth of NASA data in multiple computer models.

“With 60 years of lunar data available to us, we help our clients understand the environmental factors for any given location on the Moon,” said Blair DeWitt, CEO of Lunar Station. Combining disparate data from different sensors used by NASA and other space agencies is a critical first step. One NASA resource the Cambridge, Massachusetts-based company used to build terrain maps is the Ames Stereo Pipeline. The open-source code automatically processes images captured from satellites, robotic rovers, historical images, and more to create a 3D model revealing features such as rock placement and elevation.

But the availability of in-situ lunar water resources at any location is largely unknown, according to Gerry Sanders, in-situ resource utilization system capability lead at NASA’s Johnson Space Center in Houston. To begin to fill that gap, the Lunar Crater Observation and Sensing Satellite was designed to crash its uppers stage into the Moon’s South Pole in 2009. The examination of the resulting plume revealed the presence of water ice.

Lunar Station is building on that work and more to help commercial space companies with mission planning, which includes scientific research for mining operations. The MoonHacker program uses proprietary geospatial analytics platform and advanced algorithms to fuse all the lunar data in NASA’s Planetary Data System to help identify indicators for shallow pits of lunar water.

“We can find sites for landing pads, for cultivating the best paths for roving, and inform our clients about communications. If you can’t see Earth at a given location like in the polar regions or the far side of the Moon, you have to come up with a relay strategy,” said DeWitt. “We can do this in part thanks to NASA data.”

In MoonHacker’s Radiation Simulator, an electronic version of a company’s rover or satellite, called a digital twin, can be subjected to the radiation en route or at the mission site to determine the protection required.

These innovations exemplify the purpose of NASA’s Technology Transfer program within the Research and Technology Mission Directorate, which uses space-based solutions to improve life on Earth. For 50 years, NASA has documented the everyday benefits of space technology through the agency’s Spinoff publication.

NASA Upgrades Vertical Motion Simulator for Modern Mission Needs

Imagine stepping into a machine that can make you feel like you’re flying a spacecraft, piloting a next generation air taxi, or landing on the Moon, all without leaving the ground. NASA’s Vertical Motion Simulator, the largest of its kind in the world, does exactly that. And now, with new upgrades, it’s more powerful and realistic than before.

The Vertical Motion Simulator, located at NASA’s Ames Research Center in California’s Silicon Valley, has shaped the future of aviation and spaceflight since 1979. It allows pilots and researchers to experience realistic aircraft motion due to its ability to travel 60 feet vertically and 40 feet horizontally, simulating vehicles ranging from helicopters to spacecraft with high accuracy.

New improvements are making the simulator even more powerful. One of the biggest changes is the switch from analog systems to modern digital technology. This upgrade includes a dome surrounding the simulator’s cockpit with advanced 4K projectors that create visuals with nearly 20/20 clarity, giving pilots clearer, sharper images and a larger field of view of the world outside the cockpit.

“The new dome configuration and improved systems can support far more aggressive mission tasks while giving pilots and crews a more realistic environment to work in,” said Diana Acosta, aerospace simulation research and development branch chief at NASA Ames. “It strengthens how teams coordinate, react, and manage challenging scenarios, exactly the kind of preparation we need for the missions coming next.”

The system also can automatically line up and color‑match images to integrate them into a simulated background, a process that used to take hours, or even days, to do by hand.

In the past, changing simulation configurations from lunar lander to air taxi required swapping out the cab, a large, heavy structure that was time‑consuming and complex to move. Instead of replacing an entire cab, teams can use lighter, removable inserts that include only the controls, seats, and panels needed to stand in for a specific vehicle. The inserts drastically reduce physical labor and cut the time needed to configure a simulation in half.

The upgrades to the Vertical Motion Simulator will enable tests of next-generation aircraft and spacecraft before they ever leave the ground, bringing us closer to safer skies, more efficient air travel, and successful human landings on the Moon and Mars.
