Being Near The Equator Comes With An Energy Boost
One of the most important reasons that NASA has so many launches in Florida is the state’s proximity to the equator. The closer a launch site is to the equator, the less energy a rocket has to expend to overcome gravity and makes its way into orbit. There is a lot of math
involved when it comes to determining the physics behind a rocket launch, but one thing is clear: rocket launches take advantage of every factor they can, including the Earth’s rotation. Luckily for the astronauts in Cape Canaveral, the Earth actually rotates at a higher speed
at the equator than it does at the poles. This extra push is enough to drastically reduce the amount of energy required for a successful launch.
Failed Takeoffs Near The Ocean Are Far Less Destructive
A big advantage to launching a spacecraft near the ocean is that fewer people are at risk of being hurt in the event of a catastrophic event. As all the crafts launching out of Cape Canaveral head east, that puts the rockets directly over the Atlantic ocean. This allows multistage rockets
to safely drop back to Earth without fear of hurting anyone. When a spacecraft malfunctions, it’s critical that no debris falls in an area that is populated by humans. The ocean is basically a massive airbag that’s ready to take the brunt force of an impact so that any civilians on the ground don’t.
It Decreases The Cost Of The Space Missions
Launching anything into space is extremely expensive. At our current technological level, a rocket launch costs roughly $10,000 per pound
. That’s crazy expensive considering that the space shuttle carried roughly 1.6 million pounds
of fuel alone, which means the total to launch a rocket comes to about $450 million after
building the thing! Luckily, taking advantage of the increased speed of rotation near the equator can incur significant fiscal savings per launch compared to launch sites in other parts of the country. NASA and private companies like SpaceX are working on bringing down the cost of spaceflight
, but for now it remains an extremely expensive endeavor.
Earlier Test Sites Weren’t Working Out Because The Desert Wasn’t Big Enough
Cape Canaveral wasn’t the first NASA launch site in the country, but over the years it has become the most popular and most reliable. Before the Space Coast was born, NASA was launching rockets in the heart of New Mexico. This was just after the conclusion of World War II, so rocket technology was just starting to be used to its potential. The New Mexico launch site, known as White Sands
, was only a hundred miles in size. This proved to be insufficient for the needs of rocket scientists who were testing technologies that could clear a hundred miles in mere moments. Florida made much more sense, as the ocean was a far more forgiving testing ground.
Launching From The East Coast Takes Advantage Of The Earth’s Rotation
It’s not just the equator’s effect on the Earth’s rotation that makes Florida such a prime location for space travel. The actual direction of the rotation itself is crucial in allowing launches to be performed cheaply and more smoothly than elsewhere in America. When a rocket travels east from Cape Canaveral, it is taking advantage of the counter-clockwise rotation of the Earth
. Rockets heading east get a boost
because they are traveling with the rotation of the Earth, not against it. So it’s always easier to head east, which makes Florida the perfect candidate for space travel.
At The Time Of Its Creation, Cape Canaveral Was Relatively Unpopulated
Florida’s eastern coastline is one of the most populated regions in the country, but that wasn’t always the case. During the 1940s, Cape Canaveral was little more than a barren sandbar
. The area was pockmarked with orchards, far from the urban beaches of today. This was ideal for NASA
as they were still working with experimental technologies that had a high chance for catastrophic failure. No one was around to be injured in the event of a mission failure. On top of that, the low population density meant that the programs could be kept relatively secret and away from prying eyes.
There Was Already A Missile Testing Site In Cape Canaveral
Another draw for NASA to start building in Brevard county was the existing infrastructure. The area where the current Kennedy Space Center resides was once a missile testing site
. Missiles and rockets harness the same basic principals and can be launched in a similar fashion, so adapting an existing missile testing site for use with NASA’s rockets was a no- brainer in their eyes. The major difference between a missile and a rocket is that only one launches for the good of mankind.
A Nearby Military Base Helped To Establish The NASA Center
On top of the missile testing site, a nearby military base was also a critical factor in deciding to build a launch site in Cape Canaveral. Although the location was isolated from the public, the military presence meant that there was already significant infrastructure
in place in the region. Road and railway lines that could connect to the space center to the rest of the state would be vital for transporting supplies and people to the site. The military base was also a handy response force in the event of an emergency at the space station, which was another solid incentive for choosing the location.
Other Candidates, Like Hawaii And Puerto Rico, Were Too Isolated
Cape Canaveral wasn’t the only isolated, oceanside location near the equator that NASA could have chosen for their most significant launch site. Two other American locations, Puerto Rico and Hawaii
, also fill out the necessary qualifications for spaceflight. Obviously Hawaii is much further west, which is not as advantageous, but Puerto Rico is even closer to the equator than Florida, so why was it not chosen instead? The answer is simple; it’s an island. Both Puerto Rico and Hawaii have the disadvantage of being islands, which means it is much more difficult to get supplies to these locations. Florida was an ideal candidate as it was still part of the continental United States and was much more accessible than either Puerto Rico or Hawaii.
Private Companies Are Now Rushing To Build Spaceports In Florida
Even after a half a century and the conclusion of the traditional space shuttle launch program in 2011, Florida is still considered one of the greatest places on Earth – certainly in the US – to launch a spacecraft into orbit. As the commercial spaceflight industry continues to explode in popularity, more and more companies are eyeing Florida as a potential destination for their own launch sites. Both SpaceX and Boeing have set their sites on the sunshine state, furthering the tradition of Florida aeronautics. It seems that Cape Canaveral will be the place where Americans will travel into space from for the foreseeable future
