Launch Your Creativity with These Space Crafts!
In honor of the completion of our Nancy Grace Roman Space Telescope’s spacecraft — the vehicle that will maneuver the observatory to its place in space and enable it to function once there — we’re bringing you some space crafts you can complete at home!
Join us for a journey across the cosmos, starting right in your own pantry.
Stardust Slime
Did you know that most of your household ingredients are made of stardust? And so are you! Nearly every naturally occurring element was forged by living or dying stars.
Take the baking soda in this slime recipe, for example. It’s made up of sodium, hydrogen, carbon, and oxygen. The hydrogen was made during the big bang, right at the start of the universe. But the other three elements were created by dying stars. So when you show your friends your space-y slime, you can tell them it’s literally made of stardust!
Instructions:
1 5 oz. bottle clear glue ½ tablespoon baking soda food coloring 1 tablespoon contact lens solution 1 tablespoon glitter Directions:
Pour the glue into a bowl
Mix in the baking soda
Add food coloring (we recommend blue, purple, black, or a combination).
Add contact lens solution and use your hands to work it through the slime. It will initially be very sticky! You can add a little extra contact lens solution to make it firmer and less goopy.
Add glitter a teaspoon at a time, using as much or as little as you like!
Space Suckers
Now let’s travel a little farther, past Earth’s atmosphere and into the realm of space. That’s where Roman is headed once the whole observatory is complete and passes all of its testing!
Roman will scan the skies from space to make it extra sensitive to faint infrared light. It’s harder to see from the ground because our atmosphere scatters and absorbs infrared radiation, which obscures observations.
Some astronauts have reported that space smells metallic or like gunpowder, but don’t worry — you can choose a more pleasant flavor for your space suckers!
Ingredients
2 cups sugar 2/3 cup light corn syrup 2/3 cup water gel food coloring flavor oil edible glitter dust sucker sticks sucker mold Directions
Prep the molds by adding sucker sticks.
Mix sugar, light corn syrup, and water together in a pot on the stove over medium heat.
Turn it up to medium-high heat and let it boil without stirring for about 6 minutes.
Quickly stir in the flavor oil of your choice, gel food coloring, plus as much edible glitter as you like (reserve some for dusting).
Carefully but quickly spoon the mixture into the molds. Spin the sticks so they’re evenly coated. Add a sprinkle of reserved edible glitter and allow to harden.” An image on the left side of the card shows the result: a deep purple sucker with silver glitter embedded.
Fizzy Planets
As we move toward our outer solar system, we’ll pass the orbits of the gas giant planets Jupiter and Saturn. While they don’t actually fizz like the mini planets you can make at home, they do have some pretty exotic chemistry that stems from their extreme pressures, temperatures, and compositions. For example, the hydrogen in their cores behaves like liquid metal instead of a gas. It even conducts electricity!
Roman will use multiple planet-spotting techniques –– microlensing, transits, and direct imaging –– to help us study a variety of worlds, including both gas giants and rocky worlds similar to our own.
Ingredients
3 cups baking soda ¾ cup water food coloring ¼ cup vinegar Directions
Mix a few drops of food coloring into ¼ cup of water and pour into a bowl with 1 cup of baking soda.
Repeat step one two more times using different colors.
Scoop together bits from each mixture to form small balls. Add an extra splash of water to any mixture that’s too crumbly.
Douse the balls with vinegar using an eye dropper or teaspoon and watch them fizz!
Marshmallow Constellations
As we venture farther out into space, we’ll reach some familiar stars! Constellations are groups of stars that appear close together in the sky as seen from Earth. But if you actually journeyed out to them, you might be surprised to discover that they’re often super far apart from each other!
Though constellations aren’t made of stars that are actually bound together in any way, they can still be useful for referencing a cosmic object’s location in the sky. For example, you can use a pair of binoculars or a telescope to take a look at the nebula found beneath Orion’s Belt, marked by the glitter patch in the recipe card above! You can find the constellation printables here.
Supplies
toothpicks or mini pretzel sticks mini marshmallows constellation printables scissors Directions
Attach marshmallows to toothpicks or pretzel sticks using the constellation cards as a guide. Carefully trim toothpicks or pretzel sticks as needed using scissors.
Black Hole Bath Bombs
Black holes –– objects with such strong gravity that not even light can escape their clutches –– lurk unseen throughout our galaxy. Stray too close to one and you’re in for a wild ride! But they aren’t cosmic vacuum cleaners, despite what you may have grown to believe. Just keep your distance and they’ll affect you the same way as any other object of the same mass.
Astronomers have found dozens of black holes in our galaxy by seeing how their gravity affects nearby objects. But there may be 100 million more that lack a visible companion to signal their presence. Roman will find some of these solitary black holes by seeing how their gravity focuses the light from farther stars.
Ingredients
1 cup baking soda ½ cup citric acid ½ cup cornstarch 2 tablespoons coconut oil black food coloring optional: 2 teaspoons essential oil for scent optional: ½ cup Epsom salt Directions
Mix the baking soda, citric acid, cornstarch, and Epsom salt (optional) together in a bowl.
In a separate bowl, mix the coconut oil, food coloring, and essential oil (optional).
Pour the liquid mixture into the dry mixture slowly while whisking it all together. Add a couple tiny splashes of water and whisk it in quickly.
Tightly press the mixture into round molds. Leave them for a few hours and then they’ll be ready to use!
Galaxy in a Jar
Now let’s go so far we can see our Milky Way galaxy from the outside — something many astronomers probably wish they could do at times!
Sort of like how Earth’s atmosphere can affect our view of space, dust in our galaxy can get in the way, too. That makes it easier to study other galaxies than our own in some ways! Roman’s combination of a large field of view, crisp resolution, and the ability to peer through dust make it the ideal instrument to study the Milky Way. The mission will build on previous observations to generate the most detailed map of our galaxy to date.
Ingredients
hot water glitter glue glitter super glue (optional) Directions
Mostly fill a 16 oz. glass jar with very hot water, leaving a couple inches of space at the top.
Add at least ¼ cup of glitter glue in colors of your choosing.
Add loose glitter a couple of teaspoons at a time, using as much or as little as you like! You can use a combination of fine and chunky glitter for an extended swirling effect.
Optional: Super glue the lid to the jar.
Once the water has sufficiently cooled, give the jar a gentle shake to see your galaxy swirl!
NOTE: Closely monitor children to ensure the jar doesn’t break.
Pinwheel Galaxy Pinwheels
As we continue our cosmic excursion, you’ll see other galaxies sprinkled throughout space. Many are spiral galaxies, like our Milky Way and the Pinwheel Galaxy from the craft described above. (You can find more detailed instructions and the printout you’ll need here.)
But galaxies come in other varieties, too. Through Roman’s wide, deep surveys, astronomers are sure to see every type. Scientists will study the shapes and distances of billions of galaxies to help us understand dark energy — a mysterious pressure that’s speeding up the universe’s expansion.
Supplies
Pinwheel Galaxy printout pipe cleaner or chopsticks scissors popsicle stick single hole puncher Directions
Cut out the hexagonal shape for your galaxy pinwheel.
Make cuts down the white lines.
Punch holes in the white dots: six around the edges and one in the center.
Turn the paper so it’s face-down.
Thread a pipe cleaner through the center hole.
Going around the circle, fold each flap so the pipe cleaner goes through the hole.
Tie a knot in the pipe cleaner to secure the front of the pinwheel. Wrap the other side of the pipe cleaner around a popsicle stick.
Universe Dough
We’re nearing the end of our voyage, having traveled so far through space and time that we can take in the whole universe! We’ve learned a lot about it, but there are still plenty of open questions. Some of its biggest components, dark energy and dark matter (invisible matter seen only via its gravitational influence), are huge mysteries Roman will explore. And since the observatory will reveal such large, deep swaths of space, who knows what new puzzles we’ll soon uncover!
Ingredients 1 cup flour ½ cup salt 1 tablespoon vegetable oil ½ cup hot water food coloring glitter Directions
Mix flour and salt in a bowl.
Add several drops of food coloring to hot water, and stir into dry mixture along with the oil.
Add as much glitter as you like and knead it into the dough for several minutes.
Add water or flour as needed to adjust the consistency.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Water piping is installed near the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center in December 2014. The project to replace and upgrade the center’s high pressure industrial water system was a key milestone in preparations to test the SLS (Space Launch System) core stage ahead of the successful Artemis I launch.NASA/Danny Nowlin Employees install a 96-inch valve near the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center as part of a high-pressure industrial water upgrade project in March 2015.NASA/Danny Nowlin In this March 2022 photo, crews use a shoring system to hold back soil as they install new 75-inch piping leading from the NASA Stennis High Pressure Industrial Water Facility to the valve vault pit serving the Fred Haise Test Stand.NASA/Danny Nowlin Crews use a specially designed tool to place a new pipeline liner inside the existing carrier pipe near the Fred Haise Test Stand in 2024 in the last phase of updating the original test complex industrial water system at NASA’s Stennis Space Center.NASA/Danny Nowlin Crews prepare new pipeline liner sections for installation near the Fred Haise Test Stand in 2024 in the last phase of updating the original test complex industrial water system at NASA’s Stennis Space Center.NASA/Danny Nowlin For almost 60 years, NASA’s Stennis Space Center has tested rocket systems and engines to help power the nation’s human space exploration dreams. Completion of a critical water system infrastructure project helps ensure the site can continue that frontline work moving forward.
“The infrastructure at NASA Stennis is absolutely critical for rocket engine testing for the agency and commercial companies,” said NASA project manager Casey Wheeler. “Without our high pressure industrial water system, testing does not happen. Installing new underground piping renews the lifespan and gives the center a system that can be operated for the foreseeable future, so NASA Stennis can add to its nearly six decades of contributions to space exploration efforts.”
The high pressure industrial water system delivers hundreds of thousands of gallons of water per minute through underground pipes to cool rocket engine exhaust and provide fire suppression capabilities during testing. Without the water flow, the engine exhaust, reaching as hot as 6,000 degrees Fahrenheit, could melt the test stand’s steel flame deflector.
Each test stand also features a FIREX system that holds water in reserve for use in the event of a mishap or fire. During SLS (Space Launch System) core stage testing, water also was used to create a “curtain” around the test hardware, dampening the high levels of noise generated during hot fire and lessening the video-acoustic impact that can cause damage to infrastructure and the test hardware.
Prior to the system upgrade, the water flow was delivered by the site’s original piping infrastructure built in the 1960s. However, that infrastructure had well exceeded its expected 30-year lifespan.
Scope of the Project
The subsequent water system upgrade was planned across multiple phases over a 10-year span. Crews worked around ever-changing test schedules to complete three major projects representing more than $50 million in infrastructure investment.
“Many people working the construction jobs for these projects are from the Gulf Coast area, so it has created jobs and work for the people doing the construction,” Wheeler said. “Some of the specialty work has had people coming in from all over the country, as well as vendors and suppliers that are supplying the materials, so that has an economic impact here too.”
Crews started by replacing large sections of piping, including a 96-inch line, from the 66-million-gallon onsite reservoir to the Thad Cochran (B-1/B-2) Test Stand. This phase also included the installation of a new 25,000-gallon electric pump at the High Pressure Industrial Water Facility to increase water flow capacity. The upgrades were critical for NASA Stennis to conduct Green Run testing of the SLS core stage in 2020-21 ahead of the successful Artemis I launch.
Work in the A Test Complex followed with crews replacing sections of 75-inch piping from the water plant and installing several new 66-inch gate valves.
In the final phase, crews used an innovative approach to install new steel liners within existing pipes leading to the Fred Haise Test Stand (formerly A-1 Test Stand). The work followed NASA’s completion of a successful RS-25 engine test campaign last April for future Artemis missions to the Moon and beyond. The stand now is being prepared to begin testing of new RS-25 flight engines.
Overall, the piping project represents a significant upgrade in design and materials. The new piping is made from carbon steel, with protective linings to prevent corrosion and gate valves designed to be more durable.
Importance of Water
It is hard to overstate the importance of the work to ensure ongoing water flow. For a typical 500-second RS-25 engine test on the Fred Haise Test Stand, around 5 million gallons of water is delivered from the NASA Stennis reservoir through a quarter-of-a-mile of pipe before entering the stand to supply the deflector and cool engine exhaust.
“Without water to cool the deflector and the critical parts of the test stand that will get hot from the hot fire itself, the test stand would need frequent corrective maintenance,” Wheeler said. “This system ensures the test stands remain in a condition where continuous testing can happen.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Starfish Space has been awarded SBIR Phase III funding for a mission to inspect defunct satellites to increase opportunities to mitigate space debris. An artist’s concept image shows the company’s Otter spacecraft, which is capable of inspecting and deorbiting defunct spacecraft, in orbit.Starfish Space NASA is advancing an innovative approach to enabling commercial inspection of defunct, or inoperable, satellites in low Earth orbit, a precursor to capturing and repairing or removing the satellites.
The agency has awarded Starfish Space of Seattle, Washington, a Phase III Small Business Innovation Research (SBIR) contract to complete the Small Spacecraft Propulsion and Inspection Capability (SSPICY) mission. The award follows a Phase III study, which funded four U.S. small businesses including Starfish to develop mission concepts. Starfish Space will receive $15 million over three years to execute the mission.
The ability to inspect defunct spacecraft and identify opportunities for repair or deorbiting is critical to maintaining a safe orbital environment for spacecraft and humans. Orbital debris mitigation is a key component of NASA’s Space Sustainability Strategy.
“The SSPICY mission is designed to mature technologies needed for U.S. commercial capabilities for satellite servicing and logistics or disposal,” said Bo Naasz, senior technical lead for in-space servicing, manufacturing, and assembly in NASA’s Space Technology Mission Directorate. “In-space inspection helps us characterize the physical state of a satellite, gather data on what may leave spacecraft stranded, and improve our understanding of fragmentations and collisions, a difficult but critical factor in a sustainable space operating environment.”
The Starfish-led mission uses the company’s Otter spacecraft, a small satellite about the size of an oven, which is designed to inspect, dock with, and service or deorbit other satellites. Otter’s electric propulsion system will not only help it efficiently travel to multiple satellites, but the SSPICY demonstration also will mature the spacecraft’s ability to perform inspections using electric propulsion, an important enabling technology not typically used for rendezvous and proximity operations.
During the SSPICY mission, Otter will visit and inspect multiple U.S. owned defunct satellites that have agreed to be visited and inspected – a delicate and challenging task, as satellites move quickly and are kept far apart from each other for safety. Otter will approach within hundreds of meters of each satellite to conduct inspections during mission operations. During the inspection, Otter will gather key information about each of the debris objects including their spin rate, spin axes, and current conditions of the objects’ surface materials.
The SSPICY mission is the first commercial space debris inspection funded by NASA and supports the agency’s efforts to extend the life of satellites while reducing space debris. Satellites that are no longer in use can break apart or collide with one another, creating debris clouds that pose risk to human spaceflight, science and robotic missions in Earth’s orbit, and missions to other planets in the solar system. Data from inspections like those planned during the SSPICY demonstration will play a critical role in understanding the nature of defunct satellites and advancing solutions for reuse or disposal.
“We are excited to expand our partnership with NASA, building on our shared commitment to advancing in-space manufacturing and assembly capabilities,” said Trevor Bennett, co-founder of Starfish Space. “It’s an honor for Starfish to lead the first commercial debris inspection mission funded by NASA. We look forward to collaborating on this and future satellite servicing missions to enable a new paradigm for humanity in space.”
The Otter spacecraft is expected to launch in late 2026 and will begin performing inspections in 2027.
The SSPICY demonstration is funded and managed by NASA’s Small Spacecraft Technology program based at NASA’s Ames Research Center in California’s Silicon Valley. The award is enabled by NASA’s SBIR program, which is open to U.S. small businesses to develop an innovation or technology. These programs are part of NASA’s Space Technology Mission Directorate.
