Preparations for Next Moonwalk Simulations Underway (and Underwater)
A researcher inspects the interior of a male American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem.NASA They’re known as “living fossils”.
For over 450 million years, horseshoe crabs have been an ecologically vital part of our planet. They’re one of the few surviving species on Earth dating back to the dinosaurs.
At NASA’s Kennedy Space Center in Florida, the American horseshoe crab (Limulus polyphemus) is one of more than 1,500 types of animals and plants you can find living on its over 144,000 acres, the majority of which is managed by the U.S. Fish and Wildlife Service and National Park Service. Sharing a boundary with the Merritt Island National Wildlife Refuge and Canaveral National Seashore, NASA Kennedy is one of the most biologically diverse places in the United States.
The center’s land, water, and air species live alongside the symbols of America’s space program: the vital facilities and infrastructure that support the many launches at NASA Kennedy and Cape Canaveral Space Force Station as well as the rockets enabling humanity’s exploration of the cosmos.
Researchers measure the shell of a male and female American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. Preserving NASA Kennedy’s wildlife while also fulfilling the agency’s mission requires a balanced approach. The American horseshoe crab exemplifies that balance.
Horseshoe crabs are keystone species in coastal and estuary systems like the ones surrounding Earth’s premier spaceport. By themselves, these resilient arthropods are a strong indicator of how an ecosystem is doing to support the migratory birds, sea turtles, alligators and other wildlife who rely on it for their survival.
“The presence and abundance of horseshoe crabs influence the structure and functioning of the entire ecosystem,” said James T. Brooks, an environmental protection specialist at NASA Kennedy. “Their eggs provide a vital food source for many shorebirds in coastal habitats, and their feeding activities help shape the composition of plants and animals that live at the bottom of the ocean or in rivers and lakes. Changes in horseshoe crab populations can signal broader ecological issues, such as pollution or habitat loss.”
As featured recently on NASA+, biologists survey NASA Kennedy’s beaches regularly for horseshoe crabs, counting each one they spot and tagging them with devices that lets researchers study their migration patterns and survival rates. The devices also track the crabs’ spawning activity, habitat health, and population trends, especially during peak breeding seasons in spring and summer.
All this data helps in assessing the overall health of NASA Kennedy’s ecosystem, but horseshoe crabs also play a vital role in humanity’s health. Their blue, copper-based blood contains a substance called Limulus Amebocyte Lysate, critical for detecting bacterial contamination in medical equipment, pharmaceuticals, and vaccines.
Their unique value in ensuring biomedical safety underscores why NASA Kennedy emphasizes ecological monitoring in addition to its roles in the global space economy, national defense, and space exploration.

Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. NASA At NASA Kennedy, horseshoe crabs are protected and monitored through habitat restoration projects like rebuilding shorelines eroded by storms and minimizing human impact on nesting sites. These initiatives ensure that the spaceport’s operations coexist harmoniously with nature and deepen our understanding of Earth’s interconnected ecosystems.
On this Earth Day, NASA Kennedy celebrates the important role these ancient mariners play as we launch humanity’s future.

NASA, ESA, CSA, STScI, Michael Ressler (NASA-JPL), Dave Jones (IAC) Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from NASA’s James Webb Space Telescope. Its rings, which are only detected in infrared light, now look like “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.
“Before Webb, we weren’t able to detect most of this material, let alone observe it so clearly,” said Mike Ressler, a researcher and project scientist for Webb’s MIRI (Mid-Infrared Instrument) at NASA’s Jet Propulsion Laboratory in southern California. He discovered the rings around NGC 1514 in 2010 when he examined the image from NASA’s Wide-field Infrared Survey Explorer (WISE). “With MIRI’s data, we can now comprehensively examine the turbulent nature of this nebula,” he said.
This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.
One of these stars, which used to be several times more massive than our Sun, took the lead role in producing this scene. “As it evolved, it puffed up, throwing off layers of gas and dust in in a very slow, dense stellar wind,” said David Jones, a senior scientist at the Institute of Astrophysics on the Canary Islands, who proved there is a binary star system at the center in 2017.
Once the star’s outer layers were expelled, only its hot, compact core remained. As a white dwarf star, its winds both sped up and weakened, which might have swept up material into thin shells.

Webb’s observations show the nebula is tilted at a 60-degree angle, which makes it look like a can is being poured, but it’s far more likely that NGC 1514 takes the shape of an hourglass with the ends lopped off. Look for hints of its pinched waist near top left and bottom right, where the dust is orange and drifts into shallow V-shapes.
What might explain these contours? “When this star was at its peak of losing material, the companion could have gotten very, very close,” Jones said. “That interaction can lead to shapes that you wouldn’t expect. Instead of producing a sphere, this interaction might have formed these rings.”
Though the outline of NGC 1514 is clearest, the hourglass also has “sides” that are part of its three-dimensional shape. Look for the dim, semi-transparent orange clouds between its rings that give the nebula body.
A Network of Dappled Structures
The nebula’s two rings are unevenly illuminated in Webb’s observations, appearing more diffuse at bottom left and top right. They also look fuzzy, or textured. “We think the rings are primarily made up of very small dust grains,” Ressler said. “When those grains are hit by ultraviolet light from the white dwarf star, they heat up ever so slightly, which we think makes them just warm enough to be detected by Webb in mid-infrared light.”
In addition to dust, the telescope also revealed oxygen in its clumpy pink center, particularly at the edges of the bubbles or holes.
NGC 1514 is also notable for what is absent. Carbon and more complex versions of it, smoke-like material known as polycyclic aromatic hydrocarbons, are common in planetary nebulae (expanding shells of glowing gas expelled by stars late in their lives). Neither were detected in NGC 1514. More complex molecules might not have had time to form due to the orbit of the two central stars, which mixed up the ejected material. A simpler composition also means that the light from both stars reaches much farther, which is why we see the faint, cloud-like rings.
What about the bright blue star to the lower left with slightly smaller diffraction spikes than the central stars? It’s not part of this nebula. In fact, this star lies closer to us.
This planetary nebula has been studied by astronomers since the late 1700s. Astronomer William Herschel noted in 1790 that NGC 1514 was the first deep sky object to appear genuinely cloudy — he could not resolve what he saw into individual stars within a cluster, like other objects he cataloged. With Webb, our view is considerably clearer.
NGC 1514 lies in the Taurus constellation approximately 1,500 light-years from Earth.
The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Known as the interim cryogenic propulsion stage, it arrived at the Multi Payload Processing Facility (MPPF) at NASA’s Kennedy Space Center in Florida.
The upper stage traveled to the spaceport from ULA’s Delta Operations Center at Cape Canaveral Space Force Station.
While at the MPPF, technicians will fuel the SLS upper stage with hydrazine for its reaction control system before transporting it to the center’s Vehicle Assembly Building for integration with SLS rocket elements atop mobile launcher 1. The rocket’s solid rocket booster segments are already assembled for launch and the core stage soon will be integrated, as will the launch vehicle stage adapter. The upper stage will be mated to the adapter.
The four-story propulsion system is powered by an RL10 engine, which will provide Orion with the boost it needs to orbit Earth twice before venturing toward the Moon.
