A solar eclipse, the Perseids, bright Venus after sunset, and a deep partial lunar eclipse highlight August’s skywatching.
A solar eclipse, one of the year’s best meteor showers, Venus at its brightest in the evening sky, and a lunar eclipse to close out the month.
That’s “What’s Up” for August.
On Aug. 12, a total solar eclipse crosses northern Russia, Greenland, Iceland, and northern Spain, with a small corner of Portugal inside the path of totality.
In parts of the United States, from Alaska to North Carolina, the eclipse is partial. The Moon will take only a small bite out of the Sun, and the amount of coverage will vary with location.
Remember to watch safely. Use certified eclipse glasses or a safe solar viewer any time any part of the Sun is visible. Regular sunglasses are not safe. And never use binoculars, a telescope, or a camera without a solar filter made for the front of the optics.
Later that same night, the Perseid meteor shower will light up the sky, peaking the evening of Aug. 12 into the early morning hours of the 13th. And with a New Moon arriving on the 12th, the skies will be ideally dark.
The Perseids happen every year when Earth passes through a debris stream left behind by Comet Swift-Tuttle. As those tiny bits of comet dust hit our atmosphere at high speed, they burn up as bright streaks of light.
To view this meteor shower, look toward the northeast once it’s fully dark and watch for the constellation Perseus to clear the horizon. This is where the meteors originate, but let your eyes wander, because they can flash across any part of the sky.
For the best view, stay out late as the stars climb higher, find a dark open spot, and give your eyes 30 minutes to adjust.
Aug. 14-16, Venus reaches its greatest eastern elongation, which is its widest apparent separation from the Sun during this evening appearance.
Look low in the western sky shortly after sunset for the bright object that will outshine every star around it. Through a telescope after sunset, Venus will look close to half lit, like a tiny lunar phase.
On the night of Aug. 27, continuing into Aug. 28 for some time zones, the Full Moon slips through Earth’s shadow, resulting in a partial lunar eclipse. It will be visible from much of North and South America and parts of Europe and Africa.
At maximum eclipse, about 93% of the Moon’s diameter will be inside Earth’s dark central shadow, called the umbra. The Moon will not be completely covered, but it can look dramatically darkened, with a rusty, coppery tint along the covered edge.
Unlike a solar eclipse, a lunar eclipse is safe to watch with just your eyes. Binoculars or a small telescope can give you a closer view of Earth’s curved shadow moving across the Moon.
Here are the phases of the Moon for August.

Flammability test results for commercial-off-the-shelf webbings that meet NASA flammability requirements are reported for use in elevated oxygen environments anticipated for future lunar and Martian missions. Testing demonstrated that a webbing composed of 60% Kevlar®/40% polybenzimidazole (PBI) from Sturges Manufacturing Company, Inc., specifically the natural version, passed flammability testing per NASA-STD-6001B Test 1 using a surface ignition in J-configuration at 37% oxygen and 8.2 psia. Offgassing data are also provided for the natural webbing, which is gold colored. These findings support their potential use as suitable webbings
for softgoods applications, although final performance and wear characteristics must be validated in full configuration.
Background
An elevated oxygen environment is planned for future crewed missions to the Moon and Mars to reduce the prebreathe time before extravehicular activities. In this study, materials are being evaluated for use at 37% oxygen and 8.2 psia. An enriched oxygen environment increases the flammability risk and the need for improved fire-resistant materials. The NASA Engineering and Safety Center (NESC) developed a strategy to ensure textile materials that meet NASA flammability requirements in this environment are available to the aerospace community as the building blocks to softgoods flight hardware. The strategy is being implemented by the Mars Campaign Office and Johnson Space Center with support from the NESC. The first phase is testing commercial-off-the-shelf (COTS) textiles with high potential to meet flammability requirements.
Problem/Issue Description
Narrow woven fabrics, commonly referred to as webbing or woven tape, are used in multiple softgood applications, including crew mobility aids, restraint nets, and storage bag handles. The standard meta-aramid or nylon webbings do not meet the flammability requirements in elevated oxygen.
Test Methods/Data Collection
NASA-STD-6001B Test 1 was performed on the webbing candidates at White Sands Test Facility (WSTF) to determine the maximum oxygen concentration (MOC) at a pressure of 8.2 psia. The test was performed in an unshielded J configuration, where the cut edge of the webbing was not exposed to the flame and the igniter impinged on the front surface of the material, which included the lateral free edge of the webbing. Flammability performance after wear and tear was not assessed. The MOC test refers to the maximum oxygen concentration at which a minimum of five samples tested pass the NASA-STD-6001B criteria at a fixed pressure. One-inch-width natural and black webbings, composed of 60% Kevlar and 40% PBI produced by Sturges Manufacturing (see Figure 1), were tested. The available webbing widths range from ¼ to 8 inches.

Analysis and Results
Table 1 summarizes the webbing properties and test results. The webbings had MOCs of 37% and 35% oxygen for the natural and black webbing, respectively, at 8.2 psia. In addition, offgas testing was performed on natural webbing per NASA-STD-6001B Test Detailed test results can be found in MAPTIS links listed in the reference section.

These results should be used to select materials for incorporation into a final softgood product. The final flammability result will depend on the other components of the end item and must be tested in configuration to ensure the final product meets requirements. Individual textile results do not guarantee the performance of the finished assembly. Variations on this webbing (i.e., including but not limited to dimensions, weave type and yarn size, density, treatments, color, fiber blend, edge finish technique, the addition of features like hook and loop fasteners, and wear and tear) may affect flammability characteristics and should be evaluated before use.

NASA and its industry partners are preparing for next year’s Artemis III demonstration mission by completing new wind tunnel tests on SpaceX’s Super Heavy Version 3 rocket booster. The tests, conducted at NASA’s Ames Research Center in California’s Silicon Valley, focused on better understanding the extreme aerodynamic forces the rocket can experience during re-entry. The recent test series builds on previous testing completed at NASA Ames in 2024.
NASA is working with SpaceX to develop the company’s Starship Human Landing System (HLS) to safely carry astronauts from lunar orbit to the Moon’s surface and back. The upgraded Super Heavy rocket booster is part of SpaceX’s Starship launch system. Version 3 of Starship and Super Heavy is expected to be the basis for the Starship HLS for Artemis III in 2027 and a later crewed lunar landing in 2028.
Although Starship HLS is a lunar lander designed and built by SpaceX, NASA collaborates with commercial companies to provide access to specialized testing facilities, like the wind tunnels at NASA Ames, and technical expertise, such as the team that set up the wind tunnel testing and helped analyze the results.
“NASA has a lot of experience with unsteady aerodynamics,” said Manish Mehta, discipline lead engineer for the HLS Plume and Aero Environments team, NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We used the agency’s broad experience base of conducting wind tunnel tests for the space shuttle, the SLS (Space Launch System) rocket, and Orion spacecraft to efficiently set up and analyze the wind tunnel testing for the Super Heavy Version 3. In fact, similar testing at the Ames Unitary Plan Wind Tunnel resulted in adding strakes to SLS for Artemis II, so what we learned for Artemis II is helping us get to Artemis III and beyond.”
SpaceX’s Starship consists of a 33-engine first-stage Super Heavy rocket, or booster, and the second-stage Starship. Version 3 of Super Heavy incorporates many new and upgraded systems, including:
With significant changes to Super Heavy, NASA and SpaceX engineers wanted more information about the steady and unsteady aerodynamic forces the rocket will experience during atmospheric re-entry as it returns to the launch site for refurbishment and re-use.
“When a rocket, or an airplane, flies through air at high speed, it’s subjected to steady aerodynamic forces and moments, and unsteady aerodynamic forces and moments,” explained Jayanta Panda, unsteady aerodynamics subject matter expert at NASA Ames and part of the Human Landing System Plume and Aero Environments team. “An example of a steady aerodynamic force would be when air smoothly flows over the surface of the rocket as it ascends. An unsteady aerodynamic force would be air ‘buffeting,’ or hitting, certain areas the rocket at less predictable times and potentially causing vibrations.”
NASA and SpaceX used a 1.2% scale model of the Super Heavy Version 3 in the transonic wind tunnel and the supersonic wind tunnel at NASA Ames for testing. The transonic tunnel blasts scale models of rockets or aircraft with air at speeds ranging from Mach 0.2 to Mach 1.4 (Mach 1 is the speed of sound, or about 761 miles per hour). The smaller supersonic tunnel fires winds at higher speeds, from Mach 1.55 to Mach 2.5. The wind tunnel tests on Super Heavy Version 3, conducted in late 2025, used both tunnels to measure steady and unsteady air flows on the surfaces of Super Heavy.
“Resulting wind tunnel data on steady forces and moments helps predict how the rocket will react to forces in the atmosphere during re-entry so the flight software can effectively guide the rocket during flight,” Mehta said. “The unsteady pressure data helps engineers understand the environment around the rocket as it re-enters Earth’s atmosphere. Engineers use that information as one input into software that analyzes loads on the rocket.”
Through the Artemis program, NASA is returning humans to the Moon for scientific discovery, economic opportunity, to establish an enduring human presence on the lunar surface, and build the foundation for the first crewed missions to Mars – for the benefit of all.
