NASA is Testing A New Launch Method

NASA has teamed up with startup SpinLaunch to test a new way to launch rockets into space. Rather than the conventional launch method, it would work more like a giant “space slingshot.” Sounds pretty cool, right? That’s not even the best part. If this approach works, it could make satellite launches both cheaper and more eco-friendly. Let’s deep-dive into all the details.

How are satellites being launched into space now?

Over the past 70 years, the method used to launch satellites into space hasn’t changed much. Here’s how it works in a nutshell: load the satellites into the rocket, launch the rocket into space, and release the satellites at  the desired altitude. 

Since the rockets are reusable, we don’t have to sacrifice a new rocket for each launch, lowering this launch method’s costs. However, the propellant required to break free of Earth’s gravity is still very expensive. That’s why launching into space is so costly. 

How does the new method work? 

SpinLaunch has come up with a completely different technique for launching satellites to space. The startup has developed an A-33 Suborbital Mass Accelerator, which is supposed to work like a giant slingshot. It works by spinning the craft containing the satellites at up to 5000 miles per hour. Using a rotating carbon-fiber-arm within a 300-ft diameter steel vacuum chamber, it then releases the craft at the precise moment to hurl it nearly 30 miles beyond Earth’s surface. This method is said to reduce the need for fuel by around 70%, as compared to the conventional launch method. You can read more about how this all works here. 

While the technology is yet to be complete, NASA and SpinLaunch have already signed an agreement to test it out.
