NASA to fly payload with SpinLaunch’s mass accelerator to test low-cost, high-cadence kinetic launch system

SpinLaunch, the developer of a ground-based, electric-powered, kinetic launch system, has signed a Space Act Agreement with NASA. Through this partnership, SpinLaunch will develop, integrate, and fly a NASA payload on the company’s Suborbital Accelerator Launch System to provide valuable information to NASA for potential future commercial launch opportunities.

SpinLaunch will manifest and fly the first NASA payload on a developmental test flight later this year and provide means for post-flight recovery of payload back to NASA. The two organizations will work jointly to analyze the data and assess the system for future flight opportunities. After full review, NASA and SpinLaunch will publish all non-proprietary launch environment information from the test flight.

Ultimately, SpinLaunch’s Orbital Accelerator will accelerate a launch vehicle containing a satellite up to 5,000 miles per hour using a rotating carbon-fiber-arm within a 300-ft diameter steel vacuum chamber. After the launch vehicle ascends above the stratosphere, a small, inexpensive propulsive stage provides the final required velocity for orbital insertion and positioning. Through this unique approach, SpinLaunch is providing a fundamentally new way to access space.

The velocity boost provided by the accelerator’s electric drive results in a 4x reduction in the fuel required to reach orbit, a 10x reduction in cost, and the ability to launch multiple times per day.

The two organizations will work jointly to analyze the data and assess the system for future flight opportunities.

The company leverages existing industrial hardware and commonly available materials to construct the innovative accelerator system, achieving hypersonic launch speeds without the need for any fundamental advancements in material science or usage of emerging technologies.

The Space Act Agreement is part of NASA’s Flight Opportunities Program, which demonstrates promising technologies for space exploration, discovery, and the expansion of space commerce through suborbital testing with industry flight providers. The program is funded by NASA’s Space Technology Mission Directorate at the agency’s Headquarters in Washington, D.C. and managed at NASA’s Armstrong Flight Research Center in Edwards, California. NASA’s Ames Research Center in California’s Silicon Valley manages the solicitation and evaluation of technologies to be tested on commercial flight vehicles.

SpinLaunch is offering a unique suborbital flight and high-speed testing service, and the recent launch agreement with NASA marks a key inflection point as SpinLaunch shifts focus from technology development to commercial offerings. What started as an innovative idea to make space more accessible has materialized into a technically mature and game-changing approach to launch. We look forward to announcing more partners and customers soon, and greatly appreciate NASA’s continued interest and support in SpinLaunch.

In October 2021, SpinLaunch’s first test flight successfully propelled a test vehicle at supersonic speeds and ended with the recovery of the reusable flight vehicle. Since then, the suborbital system has conducted regular test flights with a variety of payloads at speeds in excess of 1,000 miles per hour at Spaceport America, located in New Mexico. First orbital test launches are planned for 2025.

There is high demand for Low Earth Orbit (LEO) constellations of inexpensive small satellites for disaster monitoring, weather, national security, and global communications. Leveraging an in-house Space Systems Engineering Team, as well as partnerships with existing satellite systems providers, the company is developing a complete ecosystem of satellite hardware. SpinLaunch satellite buses, and qualified subsystems, are designed to be compatible with any launch system without compromising cost, performance, or mass.​​

Through these turnkey space solutions, SpinLaunch is helping customers eliminate the cost, time, and complexity constraints currently driving space-related business models—ultimately delivering less expensive, scalable access to space.​

SpinLaunch is supported by partners, including Airbus Ventures, Google (Alphabet) Ventures, Kleiner Perkins, McKinley Capital, and ATW Partners. The company is on target to place satellites into orbit and deliver payloads for spacefaring endeavors by 2025.



Anyone got figures on the weight and volume limits for orbital flight with this?

A quick look at the website showed lots of pretty animations, and no solid figures! ;-)

I might be able to dig them out, but one of you folk may have them to hand.

Is this news 6 days late..?

This doesn't solve anything, as it only ads about 6% of the final kinetic energy.

Maximum dynamic pressure for a normal rocket comes at relatively low altitude and speed. Imagine even higher speed at lower altitude.

Going from 100 G centrifugal acceleration to zero G in that direction, but 200 G shock to the front.

Why am I even arguing against this April's Fool concept?

Actually, 5000 mph on a 150 ft arm is 11,500 G. The only thing holding up to that is the carbon fibre arm...
