NASA tests dual mode propulsion CubeSat ahead of launch

NASA has tested a dual-mode propulsion system for a CubeSat, aiming to improve spaceflight safety and efficiency. The mission, called ASCENT Propulsion Dual Mode, uses a single tank of nontoxic propellant to power both high-thrust and low-thrust engines. The CubeSat, approximately the size of a shoebox, will demonstrate a propulsion system that replaces traditional separate fuel tanks and plumbing. The test included environmental and physical evaluations, such as spin, thermal vacuum, and leak tests, to ensure the system's functionality in space. The spacecraft will be launched no earlier than October 1, 2026, as a payload aboard a SpaceX Falcon 9 rocket. The test confirmed that the seals worked as intended and that the system could operate in the harsh conditions of low Earth orbit.

• The mission is led by Dr. Nehemiah Williams at NASA's Marshall Space Flight Center.
• The propulsion system uses a single tank of ASCENT propellant, which is non-toxic and efficient.
• The test included a pressurized helium leak test to verify the seals' integrity.
• The spacecraft underwent thermal vacuum testing to simulate space conditions.
• The test confirmed that the system could operate in the harsh environment of low Earth orbit.

The dual-mode propulsion system represents a significant advancement in spacecraft design. By using a single tank and eliminating separate fuel systems, the spacecraft saves mass and volume, allowing for more space for scientific instruments. The success of this test could lead to more efficient and safer spacecraft for future missions. The mission is entering its final stages of preparation, with the team completing system checks and integrating solar arrays before shipping the hardware to the launch destination.
