NASA Challenge Gives Space Thruster Commercial Boost

In its pursuit to develop groundbreaking technologies to explore space and benefit life on Earth, NASA invites the public to contribute ideas to the agency through participatory opportunities, including challenges. The Cube Quest competition – NASA’s first in-space challenge – kicked off in 2015, offering a total prize purse of $5 million.

This challenge asked university and private developer teams to complete objectives in designing, building, and delivering small satellites capable of advanced deep space operations. Throughout two challenge phases, several teams developed and tested technologies to launch small satellites, also known as CubeSats, into orbit. 

Team Miles of Tampa, Florida, was the sole team to send its CubeSat aboard 2022’s Artemis I flight test around the Moon. Team Miles was under the leadership of Wesley Faler and found members through Tampa Hackerspace, a community nonprofit workshop. From there, it grew to include software engineering, information technology, radio-frequency engineering, radiation, aerospace engineering, graphic design, and blacksmithing experts. 

“I was prototyping a plasma thruster design in my second bedroom workshop,” says Faler. “NASA’s challenge was specifically looking for wild ideas from citizen scientists – not your traditional degree or institution scientists – and that appealed to me.”

During the challenge’s ground test phases, Team Miles developed its Miles CubeSat, a breadbox-sized satellite propelled with a novel water-fueled plasma thruster. The team also created and radiation-tested its Resilient Affordable CubeSat Processor flight computer to communicate in deep space.

In total, NASA awarded $100,000 to Team Miles in the ground phase of the Cube Quest challenge. Despite not winning the in-space phase of the challenge due to a communications failure after launch, Faler emphasizes the value of participation extending beyond monetary awards, showcasing the team’s resilience and determination.

“The challenge generated publicity and public awareness for a wild idea. The fact that NASA looked at the idea and helped us advance it gave us a platform to talk to people. That is huge for these challenges – the opportunity to be heard,” says Faler.

Since the challenge ended, Faler has cofounded and become the CEO of Miles Space, Inc., a company that was born out of the innovative spirit of Team Miles. In January 2024, Miles Space was acquired by RocketStar, Inc., where Faler now serves as chief technology officer. Stemming from iterations of Faler’s original thruster, the company has developed a nuclear fusion propulsion system, a testament to the profound impact of the Cube Quest competition on commercial space technology.

As for words of wisdom for future challenge participants, Faler said, “Whether you place in the challenge or not, you haven’t lost time by participating. Being part of that process forces you to grow.”

Gateway: Forward Progress on Artemis IV

The Artemis IV mission is taking shape with major hardware for Gateway, humanity’s first space station to orbit the Moon, progressing in Turin, Italy.

NASA will launch HALO (Habitation and Logistics Outpost), center of image in background, along with the Power and Propulsion Element (not pictured) to lunar orbit ahead of the Artemis IV mission as the first elements of Gateway, the first space station to be assembled around the Moon. During that mission, astronauts will launch in the Orion spacecraft with the Lunar I-Hab, pieces of which are shown here in the foreground, and deliver it to Gateway. Lunar I-Hab is provided by ESA (European Space Agency) with significant hardware contributions from JAXA (Japan Aerospace Exploration Agency), and is one of four Gateway modules that astronauts will live and work inside as they orbit the Moon.

Thales Alenia Space completed major welding on HALO and began initial fabrication of Lunar I-Hab last year. The company is a subcontractor to Northrop Grumman for HALO, and prime contractor to ESA for Lunar I-Hab.

Along with HALO, I-Hab, and the Power and Propulsion Element, two additional Gateway modules provided by ESA and the Mohammad Bin Rashid Space Centre make up the core components of the space station. CSA (Canadian Space Agency) is providing the Canadarm3 advanced external robotic system and fixtures for science instruments.  

The international teams of astronauts living, conducting science, and preparing for missions to the lunar South Pole region from Gateway will be the first humans to make their home in deep space.

NASA Marshall Prepares for Strategic Facilities Updates 

NASA’s Marshall Space Flight Center is getting ready for the next big step in the evolution of its main campus in Huntsville, Alabama. Through a series of multi-year infrastructure projects, Marshall is optimizing its footprint to assure its place as a vibrant and vital hub for the aerospace community in the next era. 

Near-term plans call for the carefully orchestrated take-down of 19 obsolete and idle structures – among them the 363-foot-tall Dynamic Test Stand, the Propulsion and Structural Test Facility, and Neutral Buoyancy Simulator. These facilities are not required for current or future missions, and the demolitions will help the center transition to a more modern, sustainable, and affordable infrastructure.

“These facilities helped NASA make history – the Dynamic Test Stand was the tallest manmade structure in North Alabama and helped us test both the Saturn V rocket and the space shuttle,” said Joseph Pelfrey, Marshall’s Center Director. “Without these structures, we wouldn’t have the space program we have today. While it is hard to let them go, the most important legacy remaining are the people that built and stewarded these facilities and the missions they enabled. That same bold spirit fuels us, today. We are committed to carrying it forward to inspire the workforce of tomorrow.” 

Built in 1964, the Dynamic Test Stand initially was used to test fully assembled Saturn V rockets. In 1978, engineers there also integrated all space shuttle elements for the first time, including the orbiter, external fuel tank, and solid rocket boosters.

The Propulsion and Structural Test Facility – better known at Marshall as the “T-tower” due to its unique shape – was built in 1957 by the U.S. Army Ballistic Missile Agency and transferred to NASA when Marshall was founded in 1960. There, engineers tested components of the Saturn launch vehicles, the Army’s Redstone Rocket, and shuttle solid rocket boosters.

The Neutral Buoyancy Simulator, including its 1.3-million-gallon tank and control room, was built in the late 1960s. From 1969 until its closing in 1997, the facility enabled NASA astronauts and researchers to experience near-weightlessness, conducting underwater testing of space hardware and practice runs for servicing the Hubble Space Telescope. It was replaced in 1997 by a new facility at NASA’s Johnson Space Center in Houston.

Honoring the Past, Building the Future

Marshall master planner Justin Taylor said the facilities team looked at every possibility for refurbishing the old sites.

“The upkeep of aging facilities is costly, and we have to put our funding where it does the most good for NASA’s mission,” he said. “These are tough choices, but we have to prioritize function and cost over nostalgia. We’re making way for what’s next.”

To preserve NASA history, the agency has worked with architectural historians over the years on detailed drawings, written histories, and large-format photographs of the sites. Those documents are part of the Library of Congress’s permanent Historic American Engineering Record collection, making their history and accomplishments available to the public for generations to come.

Marshall facilities engineers are still finalizing the details and timeline for the demolitions. Work is expected to begin in late 2024 and end in late 2025. Additionally, to support the center’s employees and all the mission work they are doing, Marshall has a few infrastructure projects in design stages that will include the construction of two state-of-the-art buildings within the decade ahead.

A new Marshall Exploration Facility will offer a two to three story facility at approximately 55,000 square feet located within the 4200 complex. The facility will include an auditorium, along with conferencing, training, retail, and administrative spaces. The new Engineering Science Lab – at approximately 140,000 square feet – will provide a modern, flexible laboratory environment to accommodate a new focus for research and testing capabilities.

Ultimately, NASA’s vision for Marshall is a dynamic, interconnected campus. The center’s master plan features a central greenway connecting its two most densely populated zones – its administrative complex and engineering complex.

“As we look towards the aspirational goals we have as an agency, Marshall’s contributions may look different than our past but be no less important,” said Pelfrey. “And we want our partners, employees, and the community to be part of the evolution with us, bringing complementary skills and capabilities, innovative ideas, and a passion for exploration and discovery.”
