On June 5, 1991, NASA embarked on a mission that featured several firsts: For 1, this was the agency'southward first mission that included three female coiffure members, which rocks our socks. Just, on a more bizarre note, onboard the send at that place 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 learn from studying jellyfish? It turns out that humankind has more in common with these swimming mushrooms than one might think at first glance.
Why Did NASA Study Jellyfish in the Outset Place?
Space launch STS-40 was a NASA mission that'southward also known as SLS-1. "STS" stands for Space Transportation System. For those who aren't space travel enthusiasts, that's the fashion in which NASA labels its space shuttle launches and expeditions.
SLS-1 (pictured above), in this instance, refers to Spacelab Life Sciences-i. "SLS" can also mean Space Launch System, but that's the importance of the -ane. Spacelab was a removable laboratory with the purpose of studying life sciences in space. Life sciences, like your middle schoolhouse science class, involves the study of living organisms. The purpose of Spacelab was to report how animal life reacts to the weightlessness of space, also known every bit "microgravity."
Space Shuttle Columbia, which tragically disintegrated upon re-entry into World's temper in 2003, was an orbiting ship that circled the planet for 27 missions to get together evidence about what happens to the human body in outer space. For the STS-40 mission, seven humans, 30 white rodents and the two,478 jellies were brought on board. This was the first time that NASA sent jellyfish up to space, but it wasn't the get-go 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 have emerged as the stars of the evidence.
In a second mission, but not the next mission, called STS-65 (a.k.a. IML-2), jellyfish went back up into space to exist studied by scientists in one case again. This time, the crew brought over 100 newts forth. In both experiments, jellyfish were immune to replicate. Jellyfish can reproduce asexually or with a partner, so the number of jellyfish in space increased every bit the days went on.
Jellyfish, Calcium, Humans and Gravity
Jellyfish were brought to space because, believe it or not, jellyfish and humans have a similar relationship to gravity. This might seem strange at first, but close your eyes for a infinitesimal and call back most how a jellyfish moves. Usually, information technology's as if the jellyfish steers itself through the water. Rarely do jellyfishes' "umbrella heads" ever await out of proportion or reversed the way you'd encounter an umbrella open up in a rainstorm.
At that place's likewise a scientific reason why humankind's and jellyfishes' relationships to gravity are so similar. It all has to exercise with calcium. Jellyfish have calcium sulfate crystals growing under their bell (the umbrella/mushroom-type outer layer). Equally they propel through water, the crystals adjust to the gravitational pull, and that movement sends a signal to the brain that lets the jellyfish know which way is down.
People have similar crystals and fluids in the man ear, and their presence affects hairs that alarm the brain equally to what bending a person's head is at. Ever notice how if you're looking downward at your phone or a book, your head feels like information technology's at an angle that's pointing towards that ground? Jellyfish experience a similar feeling when they swim.
What Were the Findings of These Experiments?
In 1991's STS-40 mission, scientists constitute that jellyfish built-in on Globe underwent some hormonal changes in space. They also found that jellyfish born in infinite had a hard time swimming on Earth upon their return. It was noted that both jellyfish built-in on Earth and those born in microgravity — meaning an environs where there was picayune to no gravity — had difficulty orienting themselves in space. This could requite us an idea of what it will eventually exist like to accept h2o in infinite stations for people to swim in or how nosotros can expect space fisheries down the road to function.
Scientists went on to find in 1994's IML-2 mission that budding and metamorphosis of jellyfish in microgravitaional conditions 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 after existence born in microgravity conditions and were more likely to have abnormal arm development. You can read all about it in Life Into Space, a report that's bachelor for free on NASA's website.
These findings could mean 1 of two things: The jellyfish were built-in with developmental defects that hinder their movement, or they simply exercise non desire to move.
Some have speculated that this ways 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.
Equally for what information technology means for humans, it's possible that people will fall as soon as they stride on to Earth for the first time if they're born in space. They could exist directionally challenged, meaning they may struggle to align their bodies to a point to where they can commit to walking in a sure direction. It could also mean cases of vertigo, fifty-fifty when sitting.
The Transformation From Experiment to Myth
In 2013, Deep Sea News reported on the jellyfish and the study'due south findings in a humorous way. Similar a game of phone, the true story of these jellyfish was blown out of proportion. Publications cited this mission and made the assumption that the jellyfish had recently returned from space — that they had been upwards in the sky for 20 years.
This was not the case, even so; the International Infinite Station wasn't launched until 1998. A slew of articles followed, celebrating the 20th ceremony of the jellyfish allegedly living in space that entire fourth dimension. But something was majorly off: In 1993, jellyfish did not go upwardly into space.
In October of 1993, STS-58, also known every bit SLS-2, went up. This is a lot like STS-40, as well 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 fabricated a few inferences that don't add up with the dates and bachelor data.
What Does This Mean for the Time to come of Space Travel?
If people ever want to live on another 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 pregnant period of time is likewise important, especially if humans are eventually going to be born in space. There'southward a run a risk that humans born in infinite might face developmental struggles.
Thankfully, NASA has been looking at people more closely in this matter. In the recent Twins Study, one twin lived in space for a year while the other stayed on Earth as a command subject. The report institute that entering the microgravity of space later being on Earth for so long, and so afterward going back to World, tin take quite a cost on the torso. Like every borderland, humankind has a lot of exploration to do before we'll fully sympathise just how well we tin accommodate to living in space.
Every bit for the jellyfish of NASA, if nosotros always arrive into space long-term, they'll be touted as heroes for World and humankind. Perhaps it's fitting, and then, that the thought of them invokes legend. While jellyfish may exist an invasive species, it's comforting to know that they also have a hard time figuring out which way is upwards.
