The NASA Innovative Advanced Concepts (NIAC) program has created 18 new awards to support visionary ideas to improve aerospace technologies in areas ranging from the exploration of the solar system to understanding the universe.

The 18 NIAC Phase I awards total $3.2 million. Each award provides up to $175,000 for a nine-month initial investigation. The NIAC projects are about early-stage concept development and are not considered official NASA missions.

“NASA has outlined an ambitious vision for the future of space exploration, we’re returning the Moon to stay, advancing to Mars, and pushing to deepen our understanding of space,” said Greg Stover, director of the Advanced Research and Technology division within the Research and Technology Mission Directorate at NASA Headquarters in Washington. “Achieving that will require more than incremental technological advancement. It means we need great leaps. These awards are the kinds of innovation the world needs NASA to help foster.”

As an innovation incubator, NIAC funds early development of potential breakthrough technologies. Concepts for award consideration must have both transformative potential and possible feasibility for eventual implementation.

“Every innovation, every leap in technology, starts with a seed of an idea,” said Phillip Williams, NIAC’s acting program executive. “The NIAC program allows NASA to germinate those seeds and determine if there’s something that could be grown to benefit future space missions and our nation’s aerospace economy.”

As NASA and its partners push for sustained lunar presence, some of the 2026 awardees focused on ways to help explore the Moon and build infrastructure there. These include a system to support hovering robots to explore lava tubes under the Moon’s surface, a method to manage temperatures for small mobile exploration robots, and a way to incorporate radioisotopic heat sources into suits to help keep astronauts warm when operating in the Moon’s nearly two-week-long lunar nights.

Other concepts focus on exploring some of the solar system’s most remarkable features. Venus, with its hot atmosphere, presents an imposing challenge for research vehicles, so one NIAC awardee explores methods for hardening instruments for longer missions.

Two other concepts could help study planetary rings. One would use a swarm of 10,000 tiny satellites to map and analyze the rings of Saturn, while another would create a system for collecting samples from rings such as those circling Saturn, Uranus, and Neptune.

Some NIAC awardees will look far beyond the solar system, exploring ways to power interstellar spacecraft, map out continents on exoplanets, observe the photon rings around black holes, and detect subtle gravitational waves to explain how galaxies formed. Others will work to answer questions directly related to life on Earth, like the potential use of spaceborne dust to reduce solar radiation, and awareness about the debris orbiting Earth.

Researchers, known as NIAC Fellows, will investigate their concepts and identify potential challenges and opportunities for further development.

Description

NASA’s Curiosity Mars rover captured this sand-capped butte, nicknamed “Miraflores,” estimated to be about 20 feet (6 meters) tall, with its Mast Camera, or Mastcam, on June 11, 2026, the 4,923rd Martian day, or sol, of the mission. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley Curiosity is climbing through. 

The surrounding area includes an expanse of terrain covered in surface features called polygons.

The panorama is made up of 11 individual images that were sent to Earth and stitched together. The color has been adjusted to match lighting conditions as the human eye would see them on Earth.

Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio. Malin Space Science Systems in San Diego built and operates Mastcam.

Description

NASA’s Curiosity Mars rover captured this 360-degree view of an expanse of terrain covered in surface features called polygons on June 19 and 20, 2026, the 4,930th and 4,931st Martian days, or sols, of the mission. The rover has found polygons several times in the past, but never so many in one place. Across the center of this image, the surface is covered by shapes ranging in size from roughly 2 to 4 inches (5 to 10 centimeters) in diameter. The features also surround and wrap around a sand-capped butte nicknamed “Miraflores,” seen at far right in the image.

Figure A is a crop from the bottom-center of the panorama highlighting the polygons and their honeycomb-like textures.

Polygonal textures can form from a variety of conditions, including drying out of the surface (like in mud cracks), temperature cycles, compaction after being buried, or shrinkage of the sediment from loss of water or mineral changes. Scientists are measuring characteristics of these polygons to home in on which process formed them.

This panorama was captured by Curiosity’s Mast Camera, or Mastcam, as the rover continued its ascent of the foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that it’s been climbing since 2014. 

The panorama is made up of 340 individual images that were sent to Earth and stitched together. The color has been adjusted to match lighting conditions as the human eye would see them on Earth.

NASA’s Curiosity Mars Rover Discovers Field of Honeycomb Textures

Preparations for Next Moonwalk Simulations Underway (and Underwater)

As NASA’s Curiosity rover recently began climbing up a Martian valley nicknamed “Valle Grande,” it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each one about 1.5 to 3 inches (4 to 8 centimeters) across. The mission has spotted small patches of these geometric shapes several times before, but nothing at the scale discovered in Valle Grande.

In a 360-degree panorama that the rover captured on June 19 and 20, the 4,930th and 4,931st Martian days, or sols, of the mission, the polygonal shapes spread in all directions for as far as the rover can see. They even wrap around the sides of a nearby butte nicknamed “Miraflores,” which stands 20 feet (6 meters) tall and is topped with a thick cap of sand.

“We’ve seen a lot of fascinating landscapes through Curiosity’s eyes, but this sea of polygons took our breath away,” said the mission’s project scientist, Ashwin Vasavada of NASA’s Jet Propulsion Laboratory in Southern California. “We measured their shapes and chemistry carefully and are hopeful there are clues in the data as to how these features formed.”

Some of the polygons that the mission has spotted in the past clearly formed as mud cracks, though a variety of processes can contribute to their honeycomb textures, including cycles of warm and cold temperatures or compression that squeezed water out of the sediment when the surface was buried.

These newly discovered polygons are among the many surprises Curiosity has trundled across since landing on Mars 14 years ago, on Aug. 5, 2012. Besides sulfur crystals, shiny meteorites, and other interesting geologic features, the rover has made major discoveries about the ancient Martian environment — most importantly, that it had the water, chemistry, and nutrients to support microbial life.

Billions of years ago, lakes and streams dappled the lower foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014. The rover has previously uncovered chemistry left over from Mars’ watery history, including carbon-based molecules believed to be precursors to RNA and DNA, two nucleic acids that carry genetic information. Scientists have no way of knowing whether these organic molecules were created by biologic or geologic processes — either path is possible — but their discovery reconfirmed that ancient Mars had the right chemistry to support life.
