🚀 Asteroid Grab: A New Space Future? 🌠
Science
🎧
TransAstra, a Los Angeles-based company, has been developing technology previously tested on the International Space Station. The company intends to capture a small, near-Earth asteroid, approximately the size of a house, using a large bag. A customer has agreed to fund a study of this “New Moon” mission, aiming to relocate the asteroid for robotic research into materials processing and manufacturing. The company envisions utilizing asteroids as sources for propellant and minerals, potentially harvesting them at the Earth-Sun L2 point, roughly 1.5 million kilometers from Earth. TransAstra’s initial mission, projected to cost a “few hundred million” dollars, represents a significantly scaled-up approach compared to missions like NASA’s OSIRIS-REx, which returned just 121.3 grams of material from Bennu. The company is currently evaluating spacecraft providers and anticipates a complex undertaking involving the retrieval of substantial quantities of asteroid material.
ASTEROID CAPTURE MISSION: A NEW APPROACH
TransAstra, a Los Angeles-based company, has developed a revolutionary plan to capture and relocate near-Earth asteroids, presenting a potentially transformative approach to space resource utilization and robotic research. The core of their strategy involves deploying a “capture bag”—a large, expandable structure constructed from materials like Kapton—to envelop an asteroid and subsequently tow it to a designated processing facility. This innovative technique represents a significant departure from traditional space exploration methods, focusing on in-situ resource harvesting and manufacturing.
TECHNOLOGICAL DEVELOPMENT AND TESTING
The feasibility of TransAstra’s concept has been rigorously tested through a series of meticulously planned experiments. In September of the previous year, a 1-meter prototype capture bag was successfully launched to the International Space Station aboard a Cygnus spacecraft. An astronaut then conducted a crucial demonstration, opening and closing the bag within the vacuum of the Bishop airlock, confirming its functionality in the harsh conditions of space. Furthermore, TransAstra secured a $2.5 million contract from NASA to scale up the capture bag system to 10 meters in diameter, a size deemed necessary for effectively corralling smaller asteroids. This combined investment, alongside private funding, has dramatically accelerated the development and testing phases of the larger capture bag system, positioning TransAstra at the forefront of this ambitious endeavor.
MISSION PHASING AND RESOURCE UTILIZATION
The proposed “New Moon” mission, funded by an unnamed customer, aims to capture and relocate an asteroid approximately the size of a house, weighing around 100 metric tons. The initial target is one of an estimated 250 potential asteroids, each with a diameter of up to 20 meters, reachable within the next decade using reusable robotic spacecraft. The eventual processing facility, potentially located at the Earth-Sun L2 point (approximately 1.5 million km from Earth), would serve as a hub for aggregating and processing these asteroids. Such asteroids hold immense potential, offering resources like water for propellant production and minerals for applications ranging from solar panels to radiation shielding. While the prospect of returning several kilograms of asteroid material is ambitious, TransAstra’s goal is to retrieve significantly larger quantities—potentially hundreds of tons—at a considerably lower cost, estimated at “a few hundred million” dollars. This represents a dramatically more efficient and scalable approach compared to missions like NASA’s OSIRIS-REx, which cost over $1 billion to return just 121.3 grams of material from Bennu.
