The widespread commercial adoption of additive manufacturing technologies, commonly known as 3D printing, is no surprise to design engineers at NASA\u2019s Marshall Space Flight Center whose research created stronger, lighter weight materials and new manufacturing processes to make rocket parts.<\/p>\n
NASA\u2019s RAMPT (Rapid Analysis and Manufacturing Propulsion Technology) project is on the cutting edge of additive manufacturing \u2013 helping the agency and industry produce new alloys and additively manufactured parts, commonly referred to as 3D printing, according to Paul Gradl, the project\u2019s co-principal investigator at Marshall.<\/p>\n
\u201cAcross NASA\u2019s storied legacy of vehicle and hardware design, testing, and integration, our underlying strength is in our application of extremely durable and severe environment materials and innovative manufacturing for component design,\u201d said Gradl. \u201cWe strive to fully understand the microstructure and properties of every material and how they will ultimately be used in components before we make them available to industry for flight applications.\u201d<\/p>\n
The same principle applies to additive manufacturing, the meticulous process of building components and hardware one layer of material at a time.<\/p>\n
\u201cThe RAMPT project\u2019s goal is to support commercial, technical readiness, enabling our industry partners to meet the challenges inherent in building new generations of safer, more cost-effective deep space exploration propulsion systems,\u201d said John Fikes, RAMPT project manager.<\/p>\n
Since its inception, RAMPT has conducted 500 test-firings of 3D-printed injectors, nozzles, and chamber hardware totaling more than 16,000 seconds, using newly developed extreme-environment alloys, large-scale additive manufacturing processes, and advanced composite technology. The project has also started developing a full-scale version for the workhorse RS-25 engine \u2013 which experts say could reduce its costs by up to 70% and cut manufacturing time in half.<\/p>\n
As printed structures are getting bigger and more complex, a major area of interest is the additive manufacturing print scale. A decade ago, most 3D-printed parts were no bigger than a shoebox. Today, additive manufacturing researchers are helping the industry produce lighter, more robust, intricately designed rocket engine components 10-feet tall and eight-feet in diameter.<\/p>\n
\u201cNASA, through public-private partnerships, is making these breakthroughs accessible to the commercial space industry to help them rapidly advance new flight technologies of their own,\u201d Gradl said. \u201cWe\u2019re solving technical challenges, creating new supply chains for parts and materials, and increasing the industry\u2019s capacity to rapidly deliver reliable hardware that draws a busy commercial space infrastructure ever closer.\u201d<\/p>\n
The RAMPT project does not just develop the end technology but the means to fully understand that technology, whatever the application. That means advancing cutting-edge simulation tools that can identify the viability of new alloys and composites at the microstructural level \u2013 assessing how they handle the fiery rigors of liftoff, the punishing cold of space, and the dynamic stresses associated with liftoffs, landings, and the long transits between.<\/p>\n
NASA\u2019s strategy to encourage commercial and academic buy-in is to offer public-private partnership opportunities, wherein industry and academia contribute as much as 25% of project development costs, allowing them to reap the benefits.<\/p>\n
For example, NASA successfully delivered a refined version of an alloy, known as\u00a0GRCop42, created at NASA\u2019s Glenn Research Center nearly 40 years ago which helped commercial launch provider, Relativity Space, launch the first fully\u00a03D-printed rocket\u00a0in March 2023.<\/p>\n
\u201cOur primary goal with these higher-performance alloys is to prove them in a rocket engine test-fire environment and then hand them off to enable commercial providers to build hardware, fly launch vehicles, and foster a thriving space infrastructure with real scientific, social, and economic rewards,\u201d Gradl said.<\/p>\n
A key benefit of additive manufacturing hardware development is radically reducing the \u201cdesign-fail-fix\u201d cycle \u2013 when engineers develop new hardware, ground-test it to failure to determine the hardware\u2019s design limits under all possible conditions and then tweak accordingly. That capability is increasingly important with the creation of new alloys and designs, new processing techniques, and the introduction of\u00a0composite overwraps\u00a0and other innovations.<\/p>\n
The RAMPT project did just that, successfully advancing new additive manufacturing alloys and processes, integrating them with carbon-fiber composites to reduce weight by up to 40%, developing and validating new simulation tools \u2013 and making all this data available to industry through public-private partnerships.<\/p>\n
\u201cWe\u2019re able to deliver prototypes in weeks instead of years, conduct dozens of scaled ground tests in a period that would feasibly permit just one or two such tests of conventionally manufactured hardware, and most importantly, deliver technology solutions that are safer, lighter, and less costly than traditional components,\u201d Gradl said.<\/p>\n
Fikes added, \u201cTen years from now, we may be building rocket engines \u2013 or rockets themselves \u2013 out of entirely new materials, employing all-new processing and fabrication techniques. NASA is central to all of that.\u201d<\/p>\n
The RAMPT project continues to progress and receive recognition from NASA and industry partners. On July 31, the RAMPT team was awarded NASA\u2019s 2024 Invention of The Year award for its excellence and contributions to NASA and the commercial industry\u2019s deep space exploration goals.<\/p>\n
Marshall leads RAMPT, with key support among engineers and technologists at NASA\u2019s Glenn Research Center; Ames Research Center; Langley Research Center; and Auburn University in Auburn, Alabama, plus contributions from other academic partners and industry contractors. RAMPT is funded by NASA\u2019s\u00a0Game Changing Development Program\u00a0within the agency\u2019s\u00a0Space Technology Mission Directorate.<\/p>\n

Caused by Earth passing through trails of debris left behind by\u00a0Comet Swift-Tuttle, the shower has become famous over the centuries because of its consistent display of celestial fireworks.<\/p>\n \u201cThe Perseids is the best annual meteor shower for the casual stargazer,\u201d said Bill Cooke, who leads NASA\u2019s\u00a0Meteoroid Environment Office\u00a0at the agency\u2019s Marshall Space Flight Center. \u201cNot only is the shower rich in bright meteors and fireballs \u2013 No. 1 in fact \u2013 it also peaks in mid-August when the weather is still warm and comfortable. This year, the Perseid maximum will occur on the night of Aug. 11 and pre-dawn hours of Aug. 12. You\u2019ll start seeing meteors from the shower around 11 p.m. local time and the rates will increase until dawn. If you miss the night of the 11th, you will also be able to see quite a few on the night of the 12th between those times.\u201d<\/p>\n The best way to see the Perseids is to find the darkest possible sky and visit between midnight and dawn on the morning of Aug. 12. Allow about 45 minutes for your eyes to adjust to the dark. Lie on your back and look straight up. Avoid looking at cell phones or tablets because their bright screens ruin night vision and take your eyes off the sky.<\/p>\n Perseid meteors travel at the blistering speed of 132,000 mph \u2013 or 500 times faster than the fastest car in the world. At that speed, even a smidgen of dust makes a vivid streak of light when it collides with Earth\u2019s atmosphere. Peak temperatures can exceed 3,000 degrees Fahrenheit as they speed across the sky. The Perseids pose no danger to people on the ground as practically all burn up 60 miles above our planet.<\/p>\n The first Perseid captured by\u00a0NASA\u2019s All Sky Meteor Camera Network\u00a0was recorded at 9:48 p.m. EDT on July 23. The meteor \u2013 about as bright as the planet Jupiter, so not quite bright enough to be considered a fireball \u2013 was caused by a piece of Comet Swift-Tuttle about 5 millimeters in diameter entering the atmosphere over the Atlantic and burning up 66 miles above St. Cloud, Florida, just south of Orlando.<\/p>\n Rare Fireball in New York, New York Not Perseids<\/strong><\/p>\n It wasn\u2019t part of the Perseids, but a rare daylight fireball streaked across the sky over New York City at 11:15 a.m. EDT on\u00a0 July 16. The event gained national attention and was reported in media outlets across the U.S.<\/p>\n The fireball, defined as a meteor\u00a0brighter than the planet Venus, is estimated to have soared over New York City before traversing a short path southwest and disintegrating about 31 miles above Mountainside, New Jersey. Cooke said the meteor was likely about 1 foot in diameter, which would have made the rock bright enough to see during the day. Seeing a meteor of this size is rarer than catching sight of the smaller particles a few millimeters in size typically seen in the night sky.<\/p>\n \u201cTo see one in the daytime over a populated area like New York is fairly rare,\u201d Cooke said during an\u00a0interview\u00a0with ABC 7 in New York.<\/p>\n The\u00a0Meteoroid Environments Office\u00a0studies meteoroids in space so that NASA can protect our nation\u2019s satellites, spacecraft and even astronauts aboard the International Space Station from these bits of tiny space debris.<\/p>\n For more skywatching highlights in April, check out Jet Propulsion Lab\u2019s What\u2019s Up series.<\/p>\n \n
