Key Takeaways
- NASA has contracted Impulse Space to conduct studies on orbital transfer vehicle (OTV) services for cost-effective spacecraft delivery.
- Impulse Space’s Mira and Helios vehicles aim to enhance payload delivery to challenging orbits, offering improved performance and flexibility.
- These developments could enable NASA to undertake a broader range of scientific, commercial, and defense missions beyond current launch capabilities.
Nasa’s Innovative Partnership with Impulse Space
NASA has chosen Impulse Space, based in Redondo Beach, California, to carry out two studies focusing on orbital transfer vehicle (OTV) services. This initiative, part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare Launch Services (VADR) contract, aims to explore more affordable options for delivering spacecraft to complex orbits.
The studies will investigate how the Mira and Helios vehicles can facilitate the deployment of multiple payloads from a single launch or enable individual spacecraft to reach destinations that are beyond the capability of existing launch vehicles. This capability is crucial for enhancing NASA’s mission profiles and extending its operational reach for various scientific and defense-related tasks.
Mira is a high-thrust, maneuverable OTV that has shown successful operation in low Earth orbit (LEO) and can also venture into medium Earth orbit (MEO), geostationary orbit (GEO), and cislunar space. The updated design of Mira boasts a 25% increase in delta-v, enabling it to achieve speeds of up to 900 meters per second for payloads of 100 kilograms. Notable advancements include upgraded Saiph thrusters, enhanced solar arrays, improved avionics, and added security features such as NSA Type 1 cryptography. The spacecraft can dynamically reconfigure missions on orbit, providing flexibility for various operations.
Helios functions as a high-energy kick stage capable of transporting over 5 metric tons from LEO to GEO within a 24-hour timeframe. It offers significant delta-v options, allowing it to reach MEO, GEO, trans-lunar injection, and beyond based on payload weight. The vehicle is propelled by a Deneb 67-kilonewton liquid oxygen/liquid methane engine and is compatible with multiple rocket systems, including Falcon 9, Falcon Heavy, and more. Its design accommodates diverse payload sizes and configurations.
Tom Mueller, founder and CEO of Impulse Space, remarked, “Mobility is the next great unlock for space,” emphasizing the importance of commercial in-space mobility. He expressed pride in supporting NASA’s initiative to leverage these advancements for more flexible missions, reduced costs, and expanded possibilities in orbit.
Through this collaboration, NASA aims to push the limits of space exploration by integrating commercial technologies, potentially transforming future mission planning and execution.
