Los Angeles-based TransAstra is pursuing a bold, and some might say fantastical, plan to capture a compact asteroid and bring it closer to Earth. The company announced Wednesday it has begun an investor- and customer-funded study, dubbed “New Moon,” to assess the feasibility of capturing and relocating a near-Earth asteroid for use in space-based industries. This ambitious project aims to establish a readily accessible source of raw materials for manufacturing and propellant production in orbit, potentially revolutionizing space exploration and development.
The proposed mission targets asteroids roughly the size of a house, with an estimated mass of around 100 metric tons. According to Joel Sercel, TransAstra’s chief executive officer, the captured asteroid would serve as a “base for robotic research and development on materials processing and manufacturing.” The long-term vision, Sercel explained, is to shift the paradigm of space hardware creation, moving away from building everything on Earth and launching it into orbit, and instead harvesting resources directly from asteroids. This concept of asteroid mining has been discussed for decades, but TransAstra’s plan represents a concrete step toward realizing that potential.
A Fleet of Space Rocks
TransAstra estimates there are as many as 250 potential target asteroids within reach using reusable, robotic spacecraft over the next decade. These asteroids, with diameters up to approximately 20 meters, could be gathered and brought to a central “New Moon” processing facility. The company envisions eventually aggregating dozens, and ultimately hundreds, of these small asteroids at this location. Ars Technica reports that the proposed location for this facility is the Earth-Sun L2 point, approximately 1.5 million kilometers from Earth – a gravitationally stable location ideal for long-term operations.
The potential benefits of such a facility are significant. Asteroids contain valuable resources, including water, which can be broken down into hydrogen and oxygen for use as rocket propellant. They also hold minerals essential for constructing solar panels, radiation shielding, and other vital components for space infrastructure. Different asteroid types offer different advantages; C-type asteroids are rich in water, while M-type asteroids are abundant in metals. This ability to source materials in space could dramatically reduce the cost and complexity of future space missions.
Feasibility Study and Collaboration
While the concept is ambitious, TransAstra acknowledges the challenges ahead. Sercel emphasized that the current phase is a feasibility study, scheduled for completion in May, which will refine the mission plan, trajectory, and spacecraft requirements. The study will determine the technical and economic viability of the “New Moon” mission. If fully funded, TransAstra anticipates a rendezvous with an asteroid as early as 2028 or 2029. SpaceNews reported that the mission aims to move a 100-ton asteroid into a stable orbit for processing.
TransAstra isn’t undertaking this endeavor alone. The company is collaborating with the University of Central Florida, Purdue University, and NASA’s Jet Propulsion Laboratory/Caltech to conduct the necessary analysis and develop the required technologies. This partnership leverages the expertise of leading academic and government institutions to address the complex engineering and scientific challenges involved in asteroid capture and relocation.
The L2 Lagrange Point: A Strategic Location
The Earth-Sun L2 Lagrange point, where TransAstra proposes locating its “New Moon” facility, offers several advantages for space operations. Located approximately 1.5 million kilometers from Earth, it provides a stable gravitational environment where a spacecraft can remain with minimal fuel expenditure. This makes it an ideal location for long-duration missions, such as asteroid processing and resource extraction. L2 offers a clear view of deep space, unobstructed by Earth or the Moon, making it suitable for astronomical observations.
The success of the “New Moon” mission hinges on overcoming significant technical hurdles, including developing reliable asteroid capture mechanisms, precise navigation and trajectory control, and efficient resource extraction techniques. However, if TransAstra can demonstrate the feasibility of this concept, it could pave the way for a new era of space resource utilization, transforming our ability to explore and inhabit the cosmos. The completion of the feasibility study in May will be a crucial milestone in determining the future of this ambitious project.

The company plans to share its findings from the feasibility study upon its completion, providing further insight into the challenges and opportunities of asteroid capture and resource utilization.
