Long before astronauts travel to space, they must train here on Earth. How do you simulate spacewalks and microgravity while still on this planet? Go underwater! Astronaut: Ocean to Orbit reveals the high-tech ways NASA uses subaquatic environments to mimic life and work in space. Join International Space Station Commander Chris Cassidy as he trains in a giant underwater facility in Houston, and dive to the seafloor with astronaut Jeanette Epps as she lives underwater for ten continuous days at Aquarius Reef Base in Florida.

In 2013, a critical life-support system on the International Space Station failed, requiring an immediate spacewalk to fix it. NASA astronaut Chris Cassidy made the repair and saved the space station. As an astronaut, he was trained extensively for space walks. But how do astronauts train here on Earth to work in the microgravity of space? Astronaut: Ocean to Orbit explores the ways in which NASA uses underwater environments to simulate life and work in space, offering a fascinating look into the high-tech world of astronauts. Join astronaut Chris Cassidy (current ISS Commander) as he trains in his space suit alongside a full-sized mock-up the International Space Station in a giant underwater facility in Houston. Dive to the sea floor with NASA astronaut Jeanette Epps as she lives underwater with fellow astronauts for ten continuous days at Aquarius Reef Base in Florida. Find out what it takes to live and work in space.
What you know about rollin' down in the deep?
When your brain goes numb, you can call that mental freeze
When these people talk too much, put that shit in slow motion, yeah
I feel like an astronaut in the ocean, ayy

I feel like an astronaut in the ocean
She say that I'm cool (damn straight)
I'm like "yeah, that's true" (that's true)
I believe in G-O-D (ayy)
Don't believe in T-H-O-T
She keep playing me dumb (play me)
I'ma play her for fun (uh-huh)
Y'all don't really know my mental
Lemme give you the picture like stencil
Falling out, in a drought
No flow, rain wasn't pouring down (pouring down)
See, that pain was all around
See, my mode was kinda lounged
Didn't know which-which way to turn
Flow was cool but I still felt burnt
Energy up, you can feel my surge
I'ma kill everything like this purge (ayy)
Let's just get this straight for a second, I'ma work
Even if I don't get paid for progression, I'ma get it (get it)
Everything that I do is electric
I'ma keep it in a motion, keep it moving like kinetic, ayy (yeah, yeah, yeah, yeah)
Put this shit in a frame, better know I don't blame
Everything that I say, man I seen you deflate
Let me elevate, this ain't a prank
Have you walkin' on a plank, la-la-la-la-la, like
Both hands together, God, let me pray (now let me pray)
Uh, I've been going right, right around, call that relay (Masked Wolf)
Pass the baton, back and I'm on
Swimming in the pool, Kendrick Lamar, uh
Want a piece of this, a piece of mine, my peace a sign
Can you please read between the lines?
My rhyme's inclined to break your spine
They say that I'm so fine
You could never match my grind
Please do not, not waste my time

For me, the ocean and space have always gone hand in hand. Both are challenging, low oxygen environments but both hold wonder, curiosity and imagination for so many. They unite us as to the beauty of our planet. As soon as I took my first breath underwater, I was absolutely hooked, but little did I know where diving would lead me and how it would also help me on my journey to becoming an astronaut.

On June 6th, 2019, Australian rap artist Masked Wolf released his single "Astronaut In The Ocean,"[1] gaining some success in Australia but failing to become popular worldwide (shown below). In an interview with Tone Deaf[2] Masked Wolf talks about how the song deals with feelings of depression and anxiety, illustrated in the song by Masked Wolf rapping that he feels like an "astronaut in the ocean." The video has since gained over 59 million views on YouTube.
On May 6th, Anthony Fantano posted a video to YouTube[6] titled, "I feel like an astronaut in the ocean" in which he offers his opinions of the song, particularly critiquing the lyrics and general idea of feeling like an astronaut in an ocean as funny (shown below).
In 1984, NASA astronaut Kathy Sullivan made history as the first American woman to walk in space. Now, 36 years later, Sullivan has made history again as the first woman to travel to the deepest part of the ocean floor.
The 68-year-old former astronaut descended with explorer Victor Vescovo, who funded the expedition, in a submersible named Limiting Factor. The specially designed submersible can withstand 2,425 tons of pressure on its titanium hull. Limiting Factor is the first vehicle that has repeatedly gone to the bottom of the ocean, according to EYOS.
Sullivan, who comlpeted three shuttle missions to space, has also conducted multiple oceanographic expeditions, according to her biography on NASA's website. She has previously served as the administrator of the National Oceanic and Atmospheric Administration and was inducted into the Astronaut Hall of Fame in 2004.
Following in Sullivan's footsteps, astronauts Christina Koch and Jessica Meir completed the first-ever all-female spacewalk last October, as Andrea Michelson reported for Smithsonian magazine at the time.

A helicopter lifts a 72 kg astronaut 15 m vertically from the ocean by means of a cable. The acceleration of the astronaut is g10. How much work is done on the astronaut by the force from the helicopter ?
When I learned that I was going to be on the JR for 2-month traveling to a very remote location of the Southern Ocean, I immediately thought of it as an analog mission. The question mark (?) on the map is Point Nemo. The oceanic pole of inaccessibility. It is the furthest point in the ocean from land. When you are at Point Nemo, astronauts flying overhead on the International Space Station are closer to you than any humans on land. We cruised very close to Point Nemo while on our expedition.
Mealtime is one of the biggest daily community-building activities you can have in analog. The HI-SEAS mission was specifically funded by NASA to investigate food strategies for long-duration missions. We spent 2-days eating similarly to how astronauts on the ISS currently eat, pre-prepared meals that require little preparation, and 2-days creatively cooking using freeze-dried meats and vegetables along with other shelf-stable ingredients. The crew was responsible for preparing all the meals and we alternated our cooking style every two days for the entire 4-month mission. We also ate our meals together at designated times and had to clean up after ourselves.
Getting together to celebrate birthdays, milestones like the halfway mark, or nights of entertainment occurred in both the HI-SEAS Analog and on the JR. It was fun to see everyone come together and build community and it is always one of my favorite things about analog astronaut living.
Overall, I was surprised by just how similar my two experiences were and can see why these types of extreme scientific expeditions can be used as analogs for human space flight research. I will say that one of the coolest parts about being an analog astronaut in a Mars simulation or at sea is that you get awesome patches to go along with all the amazing memories. I am very thankful for the experiences I have had, the friends I have made, and the science communication education outreach I have done.
On Thursday, NASA sent a team of astronauts and scientists more than 60 feet below sea level for a 16-day underwater expedition. NASA Extreme Environment Mission Operations 21, or NEEMO, is designed to simulate scenarios that may arise in future Mars missions.
The first half of the NEEMO mission will be led by NASA astronaut Reid Wiseman, an ISS veteran who was a naval aviator and test pilot before joining the agency. The second half of the expedition will be led by NASA astronaut Megan McArthur, a PhD oceanographer who was also involved in the 2009 STS-125 shuttle mission.
