SpinLaunch is developing a new kinetic launch system that uses a large centrifuge to accelerate payloads to hypersonic speeds before launch, reducing the need for chemical rockets by 70%. The system works by spinning a payload up to 5,000 mph inside a large vacuum chamber and then releasing it. A small rocket then provides the final boost to orbit. SpinLaunch successfully tested a 1/3 scale prototype in 2021, launching a projectile tens of thousands of feet into the atmosphere. If successful at full scale, the system could reduce launch costs by 20-fold to $500,000 per launch and allow for more frequent daily launches compared to conventional rockets. However, payloads will be limited to around 440 pounds and the g

SPIN LAUNCH Inorder to significantly reduce the cost of access to space while increasing launch frequency, a company
by the name of SpinLaunch is developing mass accelerator technology for launching payloads into orbit.SpinLaunch
creates kinetic energy space launch technologies that lessen the need for conventional chemical rockets. It is developing
a substantial, vacuum-sealed centrifuge that has the capacity to spin a satellite launch vehicle at up to 5,000 mph. Then,
at predetermined intervals, the spacecraft is released.A small booster on the satellite then burns, giving it the last boost it
needs to enter its intended orbit as the launch vehicle splits up and falls back to Earth. 70% of the fuel required to launch
a satellite usually would not be needed with this method. At least, it should since Spin Launch has not yet constructed an
orbital launch system and does not anticipate having one ready before 2025. To test its technique, it has already
constructed 165-foot suborbital a launch vehicle. NASA intends to use that technique, which propels launch vehicles to
speeds of more than 1,000 mph before launching them into the air. WHY A SPIN LAUNCH? We have been pushing into
space for the past 70 years, using enormous rockets the size of skyscrapers to blast our way out of Earth's gravity well.
While travelling into orbit on a pillar of flame is undoubtedly spectacular, the hefty cost prevents us from fully exploring
the high frontier's potential. What if there were a quicker, more efficient way to launch cargo into orbit? What if we just
launched them into space like a slingshot? The rocket equation, as its name suggests, sums up the issue with rockets.
This clever little piece of physics states that since the chemical energy contained in the fuel is what is required to launch
cargo into space, you must transport all of that fuel and burn it off as you soar through the air. The size of rockets is due
to this. To launch the remaining gasoline, they need to carry fuel. The approach used by SpinLaunch eliminates the need
for the majority of the fuel. It's not complicated. The core of SpinLaunch's proposed Orbital Launch System (OLS), a
massive centrifuge consists of a massive rotating arm with a diameter of about 300 feet, housed inside a massive
cylindrical vacuum chamber (it resembles a large tuna can turned on its side), with the payload fastened to the end of the
arm that is shaped like an arrowhead, and which gradually accelerates to reach 5,000 mph as it spins around the
centrifuge. At this point, the payload is ascending toward the edge of space. It will ascend to 200,000 feet above the
Earth using only the centrifuge's energy, which is the same altitude at which SpaceX typically jettisons its first-stage
rocket and ignites the second. The payload modules for SpinLaunch must follow suit. When they reach this altitude, the
arrowhead fairing will separate to reveal the actual payload, which will then be propelled the remainder of the way into
orbit by a small rocket motor.

It's a really amazing concept that made a big step toward reality last October when SpinLaunch launched a 10-foot- long
projectile "tens of thousands" of feet into the stratosphere using their 1/3-scaled OLS. The idea itself was sound. WHAT
CAN SPIN LAUNCH DO FOR US? What does this indicate for the future, then? How far could we travel with this "kinetic
energy" launch technique as opposed to the chemical energy type we are accustomed to seeing on television? The cost
of SpinLaunch's OLS will be its main benefit. According to their estimates, a fully functional system will reduce the price
of a launch to $500,000, a 20-fold decrease. Other businesses that want to send items into space, such as instruments
for research and development on their innovations, can benefit from the cost savings. The cadence will be an additional
benefit. A rocket launch requires extensive planning, from moving the large bird to the launch pad (something Space X is
getting quite inventive about) to fuelling. This implies that there may be weeks or perhaps longer between releases.
However, it might be conceivable to have several launches in a single day utilizing SpinLaunch. "IT'S A RADICALLY
DIFFERENT WAY TO ACCELERATE PROJECTILES AND LAUNCH VEHICLES TO HYPERSONIC SPEEDS" -JONATHAN
YANEY FIRST TEST FLIGHT On October 22, 2021, SpinLaunch successfully completed the first test flight of a prototype at
Spaceport America in New Mexico. A 10-foot (3.0 m) long passive projectile was launched by SpinLaunch's maiden
suborbital flight using around 20% of the accelerator's full power output, reaching an altitude of "tens of thousands of
feet." With a periphery of 108 feet (33 meters), this test accelerator is one-third the size of the operating system that is
being designed. SpinLaunch intends to incorporate a rocket engine and other internal systems in later suborbital test
flights, despite the fact that the first test flight vehicle was devoid of one. Additionally, the business intends to recycle and
reuse its automobiles. The first one was found by the corporation and is completely flyable. A few small satellites' worth
of payload, or roughly 200 kg, might be launched into orbit using the SpinLaunch orbital vehicle design. LIMITATIONS
When the projectile is spinning up, it experiences strong g-forces that are around 10,000 times stronger than gravity. This
is sufficient to rip a person's skin and muscle from their body. This means that SpinLaunch will not enter the astronaut
industry. Large satellites won't be able to be launched into orbit either. The system's predicted weight limit is payloads of
roughly 440 pounds. That weighs considerably less than items like the Hubble Space Telescope. But even if we don't use
centrifuges to put humans or massive space telescopes into orbit, SpinLaunch can still launch a lot of commercial space
endeavors. We will soon have a pretty cool new means to get things off-world if everything works when they scale it up.
