In some biology classes, teachers will place vials of spit into a funny looking contraption and let it spin around the samples until the stringy DNA separates from the rest of the saliva. It’s a pretty rudimentary experiment, but it quickly gets to the heart of not only your own genetic material, but also how centrifugal force works: Spinning really fast in a circle creates a force strong enough to push a moving object out and away from the center of its path.

But what happens when that moving object is a rocket that weighs thousands of pounds? We might find out as soon as this year, when a cryptic startup called SpinLaunch starts suborbital test flights of a rocket that is launched using an enormous centrifuge.

Here’s the gist: A centrifuge the size of a football field will spin a rocket around in circles for about an hour until its speed eventually exceeds 5,000 miles per hour. At that point, the rocket and its payload will feel forces 10,000 times stronger than gravity. When the centrifuge finally releases the rocket at launch speed, it should, practically speaking, fly through the stratosphere until it fires its engines at the periphery of our atmosphere.

A ride to the Moon for under $10 million? That’s quite a price.

Warning: This article presents information that sounds like it comes out of a high-tech Hollywood sci-fi production. I suggest you first view the patent filing linked here to verify its credibility before proceeding.

Because the patent was filed by the US Navy and is now under an “Active” status, this is the real deal. This is NOT a work of fiction.

The Short Story

Violent Detonations

Engineers have long suspected such a design could revolutionize the fuel efficiency of modern engines, but until now, there was one major problem.

And the revolution has already begun.

Today’s genetic moment is not the stuff of science fiction. It’s not Jules Verne’s fanciful 1865 prediction of a moon landing a century before it occurred. It’s more equivalent to President Kennedy’s 1962 announcement that America would send men to the moon within a decade. All of the science was in place when Kennedy gave his Houston speech. The realization was inevitable; only the timing was at issue. Neil Armstrong climbed down the Apollo 11 ladder seven years later.

The DARPA Launch Challenge has begun, with a once-stealthy startup called Astra Space aiming to launch two rockets from an Alaska spaceport within the next month and a half to win a $10 million grand prize.

The Defense Advanced Research Projects Agency set up the challenge in 2018 to serve as an added incentive for private-sector development of a highly mobile launch system that the military could use.

At first, DARPA specified that two orbital launches would have to be executed over the course of two weeks from completely separate launch sites in order to win the top prize. However, program manager Todd Master said the plan was changed for logistical and regulatory reasons. Dealing with all the hassles associated with launches from widely separated sites “wasn’t really our goal in solving the challenge,” Master told reporters today during a teleconference.

The private spaceflight company is working with Space Adventures, which has helped manage trips to the International Space Station. The tourists will fly in SpaceX’s Crew Dragon capsule, but there’s no word on when the flight will happen or how much it will cost.

SpaceX will fly four privately-paying space tourists to orbit in its Crew Dragon capsule, the company unveiled on Tuesday.

“This historic mission will forge a path to making spaceflight possible for all people who dream of it, and we are pleased to work with the Space Adventures’ team on the mission,” SpaceX president and COO Gwynne Shotwell said in a statement.

The customers will be brokered through Space Adventures, a company that’s flown private citizens to the International Space Station using Russian spacecraft. The firm said this Crew Dragon mission will allow four individuals to “see planet Earth the way no one has since the Gemini program” of the 1960s.

Steven Hawking: “I don’t think we will survive another thousand years without escaping beyond our fragile planet.”

Probably the most notable direct result of space exploration is satellites. Once we could position a ship in orbit and take telemetry, we knew we could place unmanned pieces of equipment there and just let it orbit, running on its own, while receiving orders from the ground. From those satellites, we have created a global communication system and the global positioning system (GPS) that powers most of our communications capabilities today. What can bring peace and harmony on the planet more than our ability to communicate with each other beyond geographic and political boundaries? These technologies have been enhancing and saving for years.
