Think Again Walt Disney Imagineering Nasa Space Travel
On June 5, 1991, NASA embarked on a mission that featured several firsts: For one, this was the agency's first mission that included three female crew members, which rocks our socks. Merely, on a more bizarre note, onboard the ship in that location were also 2,478 jellyfish, which had never been studied in space earlier. Why were jellyfish, out of all living things, brought to outer space to be studied? What did NASA larn from studying jellyfish? Information technology turns out that humankind has more in mutual with these swimming mushrooms than one might think at get-go glance.
Why Did NASA Written report Jellyfish in the First Place?
Space launch STS-xl was a NASA mission that'southward also known as SLS-ane. "STS" stands for Space Transportation Arrangement. For those who aren't space travel enthusiasts, that'south the way in which NASA labels its infinite shuttle launches and expeditions.
SLS-one (pictured above), in this example, refers to Spacelab Life Sciences-i. "SLS" can besides mean Space Launch System, just that's the importance of the -1. Spacelab was a removable laboratory with the purpose of studying life sciences in space. Life sciences, like your centre schoolhouse science class, involves the study of living organisms. The purpose of Spacelab was to study how animal life reacts to the weightlessness of space, also known as "microgravity."
Infinite Shuttle Columbia, which tragically disintegrated upon re-entry into Earth'southward temper in 2003, was an orbiting ship that circled the planet for 27 missions to assemble bear witness nigh what happens to the human torso in outer space. For the STS-xl mission, seven humans, 30 white rodents and the 2,478 jellies were brought on lath. This was the beginning fourth dimension that NASA sent jellyfish upward to space, but it wasn't the first time animals entered the thermosphere: Aside from rats, monkeys, bees, moths, spiders and fish have also gone into space.
The mission lasted nine days. Aside from the jellyfish, the crew tested animal equipment on the rodents and studied the nervous systems, heartbeats and blood pressures of the coiffure. Of all the findings from the trip, the jellyfish seem to accept emerged equally the stars of the show.
In a second mission, but not the adjacent mission, called STS-65 (a.grand.a. IML-two), jellyfish went back up into space to be studied by scientists over again. This time, the crew brought over 100 newts along. In both experiments, jellyfish were allowed to replicate. Jellyfish can reproduce asexually or with a partner, and so the number of jellyfish in space increased equally the days went on.
Jellyfish, Calcium, Humans and Gravity
Jellyfish were brought to space considering, believe it or non, jellyfish and humans have a similar human relationship to gravity. This might seem strange at first, but close your optics for a infinitesimal and think about how a jellyfish moves. Usually, information technology'southward every bit if the jellyfish steers itself through the water. Rarely exercise jellyfishes' "umbrella heads" e'er look out of proportion or reversed the way you'd run across an umbrella open up in a rainstorm.
At that place's also a scientific reason why humankind'southward and jellyfishes' relationships to gravity are then similar. It all has to do with calcium. Jellyfish have calcium sulfate crystals growing under their bell (the umbrella/mushroom-type outer layer). As they propel through water, the crystals conform to the gravitational pull, and that motility sends a signal to the encephalon that lets the jellyfish know which way is downwardly.
People have like crystals and fluids in the human being ear, and their presence affects hairs that alert the brain every bit to what angle a person's head is at. Ever notice how if you're looking downwards at your telephone or a book, your caput feels like it's at an angle that's pointing towards that ground? Jellyfish experience a like feeling when they swim.
What Were the Findings of These Experiments?
In 1991'south STS-40 mission, scientists found that jellyfish born on Earth underwent some hormonal changes in infinite. They also institute that jellyfish built-in in space had a hard time swimming on Globe upon their return. Information technology was noted that both jellyfish built-in on Globe and those born in microgravity — significant an surround where there was little to no gravity — had difficulty orienting themselves in space. This could give us an thought of what it will eventually be similar to accept water in space stations for people to swim in or how we tin expect infinite fisheries down the road to function.
Scientists went on to observe in 1994'southward IML-2 mission that budding and metamorphosis of jellyfish in microgravitaional weather went well. That means that jellyfish did not have many problems maturing through their life cycles and handled microgravity well. They also found that jellyfish that were developed (built-in) in infinite had a hard time adjusting to normal gravity later on being born in microgravity weather condition and were more likely to have abnormal arm development. You lot can read all nearly it in Life Into Infinite, a report that's available for free on NASA's website.
These findings could mean i of two things: The jellyfish were born with developmental defects that hinder their movement, or they but practice non want to move.
Some have speculated that this means that the jellyfish are depressed. This could mean more simply that the invertebrates are having a tough fourth dimension moving around and adjusting to gravity.
As for what it means for humans, it's possible that people will fall as soon as they step on to Earth for the beginning time if they're born in space. They could exist directionally challenged, meaning they may struggle to align their bodies to a betoken to where they can commit to walking in a certain management. It could likewise mean cases of vertigo, fifty-fifty when sitting.
The Transformation From Experiment to Myth
In 2013, Deep Ocean News reported on the jellyfish and the written report's findings in a humorous fashion. Like a game of telephone, the true story of these jellyfish was blown out of proportion. Publications cited this mission and made the supposition that the jellyfish had recently returned from space — that they had been upward in the sky for twenty years.
This was not the case, yet; the International Infinite Station wasn't launched until 1998. A slew of articles followed, jubilant the 20th anniversary of the jellyfish allegedly living in space that entire fourth dimension. But something was majorly off: In 1993, jellyfish did not go up into space.
In October of 1993, STS-58, also known as SLS-2, went upwardly. This is a lot similar STS-40, also known every bit SLS-1, which happened in 1991. NASA didn't bring jellyfish back to infinite until July 1994 for IML-2. Many of the reported findings made a few inferences that don't add up with the dates and available data.
What Does This Mean for the Future of Space Travel?
If people ever want to live on some other planet or in outer space itself, they'll need to know how the homo body will develop in microgravity situations. The ways the body reacts to Earth'due south gravity after being in space for a significant period of fourth dimension is likewise important, specially if humans are eventually going to be born in infinite. There's a run a risk that humans born in space might face developmental struggles.
Thankfully, NASA has been looking at people more than closely in this affair. In the contempo Twins Report, one twin lived in space for a year while the other stayed on Earth as a control subject. The study found that entering the microgravity of space afterwards being on Earth for then long, and then later going back to World, can take quite a toll on the body. Like every frontier, humankind has a lot of exploration to do earlier we'll fully understand but how well we tin conform to living in space.
Every bit for the jellyfish of NASA, if we e'er make it into space long-term, they'll be touted every bit heroes for Earth and humankind. Mayhap it'southward plumbing fixtures, so, that the thought of them invokes legend. While jellyfish may be an invasive species, it's comforting to know that they also take a hard time figuring out which way is up.
