NASA successfully demonstrated technology designed to help spacecraft autonomously navigate to safe landing sites on the Moon and on other planets.

An Alta-X drone equipped with the agency’s Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) guidance, navigation, and control payload completed simulated lunar descent and landing maneuvers Aug. 27. The flight took place at Rogers Dry Lake near NASA’s Armstrong Flight Research Center in Edwards, California.

During the tests, the SPLICE payload used an advanced guidance system to map the terrain and assess potential landing areas. If the system determines the targeted landing area is unsafe, the system diverts the drone to a safer location. The system generates high-resolution digital elevation maps from light-detection and sensor data.

Researchers at NASA’s Johnson Space Center in Houston developed the SPLICE payload and partnered with specialists at NASA Armstrong to integrate, test, and fly it aboard the Alta-X drone in June and July. Those tests verified communications, data handling, telemetry, and command- control performance between the SPLICE payload and the drone to prepare for a full-scale test at Voyager Technologies in Mojave, California, later this month.

“This flight test is the culmination of almost a decade of work, for the SPLICE project,” said Davis Adams, NASA project manager. “This flight raised the technology readiness level, priming it for integration into future robotic and crewed lunar flights. Validation of the guidance and navigation systems are applicable to terrestrial, lunar, and Martian descent and landing missions.”

NASA has worked with a number of commercial lunar lander providers to implement iterations of SPLICE into their platforms. A number of the landers slated for upcoming Moon Base missions leverage data collected by NASA through the development of systems like SPLICE to execute soft touchdowns on the lunar surface.

“We are coordinating with industry regarding the usage of the guidance system once the system is available in the NASA software catalog, currently planned for this fall,” Adams said. “Some of the companies also are  evaluating the system’s navigation capabilities for precision landing applications, as well as potential extensions for autonomous surface mobility.”

NASA’s Flight Opportunities project, based at NASA Armstrong, enabled flight testing of the SPLICE project early in its development that laid a foundation for it to continue advancing its technology readiness level to what it is today. Flight testing included both a descent altitude and a landing trajectory in 2019 similar to what is expected on a lunar mission and the demonstration of two NASA-developed precision landing sensor systems in 2020.

Hubble Reveals Cosmic Mystery

2026-11-04 15:59

Clumpy, irregular, cloud-like dwarf galaxy in a roughly rectangular shape is speckled with small, bright, blue points of light and larger, light pink patches throughout. Dark brown and milky white areas are also smudged throughout the center of the galaxy. The galaxy appears against a mostly black background lightly dotted with tiny white, blue and red stars and galaxies.
This is an image from NASA’s Hubble Space Telescope of NGC 4449, one of the dwarf galaxies in the Galaxies Losing Oxygen via Winds (GLOW) study. Researchers found that dwarf galaxies can hold onto only a small fraction of the oxygen made by their stars.

APOD: 2026 November 4 – The Not-So-Hidden Galaxy, IC 342

2026-11-04 05:05

APOD

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.

The face of a spiral galaxy fills the image. The galaxy has a bright yellow-ish center. A handful of large arms spiral outward from the center. Bubbles of red glowing gas and tendrils of dark dust trace the spiral arms. Foreground stars and background galaxies are sprinkled across the image.

The Not-So-Hidden Galaxy, IC 342

Explanation: “I see” IC 342, the Hidden Galaxy! Today’s image peers through the plane of the Milky Way, through all its gas, dust and stars, to unveil this spiral galaxy. IC 342 (or Caldwell 5) is one of the brightest members of the IC 342/Maffei group of galaxies. Located about 10 million light years away, this group is quite close to the Local Group that includes our Milky Way. Inaccurate accounting of the crowded and dusty Milky Way foreground has led to misunderstandings in IC 342’s history, including the theory that the galaxy was ejected from the Local Group. IC 342 has its own dust intermittently blocking the glow of hydrogen gas, indicating the presence of bright, young stars. Magnetic field maps of IC 342 reveal that magnetic fields may contribute substantially to one of the biggest galactic puzzles: how do spiral arms form?

Before the Dawn in America’s Heartland

2026-11-04 05:01

A nighttime photo taken from space shows a network of city lights in the U.S. Midwest, while colorful airglow and bright sunlight arc across Earth's curved horizon.
October 18, 2026

The predawn hours brought clear skies over much of the eastern United States on October 18, 2026. An astronaut aboard the International Space Station seized the opportunity to capture this wide-angle photo at 4:54 a.m. Central Daylight Time (09:54 Universal Time), with illuminated cities large and small arrayed across the darkened landscape.

The U.S. Midwest’s largest metropolitan areas, such as Chicago, Illinois, and Detroit, Michigan, stand out as some of the brightest features. Mid-sized cities—including Indianapolis, Indiana; Cincinnati, Ohio; and Louisville, Kentucky—and their interconnections along state and interstate highways also shine brightly.

Above the web of nighttime lights and Earth’s lower atmosphere, a diffuse layer of green and orange is visible along the horizon to the left. This band of light is airglow, produced when sunlight strikes atoms and molecules in the upper atmosphere and causes them to eject photons. To the right, light from the Sun arcs across the horizon; sunrise was about an hour away on the East Coast and about two hours away in Chicago.

Astronaut photos and other remote sensing observations of nighttime lights are scientifically valuable for tracking changes in the built environment. For example, Chicago’s lightscape appears a homogeneous pale yellow in the wide view above. But in detailed photos, like the one below, a range of colors stemming from different types of lighting is discernible. Using NASA’s extensive Gateway to Astronaut Photography of Earth archive, researchers have developed a method for distinguishing lighting types within the pixels of nighttime photos. Systematically quantifying urban lights’ brightness, color, and extent can provide insight into how cities grow and evolve.

Satellite sensors also observe changes to lighting. In particular, NASA’s Black Marble nighttime lights product suite uses satellite observations to produce science-quality records of nighttime lights across the globe at daily, monthly, and yearly time scales. In the eastern U.S., scientists have used these data to track everything from power outages and restoration following major storms to lighting changes associated with new infrastructure to transitions to LED lighting from older forms.

Astronaut photograph ISS075-E-226709 was acquired on October 18, 2026, with a Nikon Z9 digital camera using a focal length of 14 millimeters, and photograph ISS070-E-105097 was acquired on March 1, 2024, with a Nikon D5 digital camera using a focal length of 400 millimeters. They are provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The images were taken by members of the Expedition 75 and Expedition 70 crews, respectively. The images have been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Lindsey Doermann.
