- Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this video we explore the different ways we can make microgravity happen here without needing to go to space! A crucial thing for testing all your space tech as well as astronaut training!

The NASA support system started as a simple inclined plane for training during the Apollo program. Where most of the astronauts weight was supported by cables as they figured out how to walk sideways along the plane with only 1/6 "gravity" keeping them in contact with it.
Awesome, thanks for sharing!
The drop towers and the parabolic flight are the only methods realistically replicating zero g since they are putting the subject in free fall. Everything else just resists gravity with another force.
amazing explanation! i saw the parabolic flights videos before
I would be curious how much power (kW) does the 19T magnet consume? Nice video Dr. Maggie, (side note I love the song on the end of your video!) 😺👍👍
My cat always looks up attentive when she hears the cat noise at the introduction to your videos. I re-assure her it is a good cat noise 🐈
meow!
I experienced a “vomit comet” parabolic flight a few years ago. It was a great experience. Felt like the drop from a tall roller coaster without the terror. We got about ten or fifteen parabolas in during our flight. It requires very skilled pilots to hit free fall without negative g forces. They give everyone an antinausea shot before the flight to keep the plane clean these days 😉
So jealous! Would you do it again or is the next step actual space?
@@SpaceMog Heck yes, I would do it again! It's fun to mess around and do summersaults in the air, but it's also exciting to try to get an experiment to run in 30 seconds :)
Of course, orbiting the Earth would be mind-boggling.
Thanks again for so much interesting knowledge. One of the methods looks like a clock-work tourbillion. Hope that is spelled correctly. If I understand that correctly, it ensures a watch spring is not influenced by gravity in the same plane all the time.
I am new to your channel and I love your videos ❤
Thanks for subbing!
Thanks for sharing 👍
Thanks for watching
Good explanation sister
Thank you 🙂
Brilliant! I quite like the idea of parabolic flight but I don’t think I’ll be able to afford it
Its probably more affordable than you think - about $6000... I'd love to do it but not sure its worth the few minutes... :/
@@SpaceMog that’s quite a bit for a few minutes flight……however still tempting 😀
@@SpaceMog I guess that I could save up, but there are also the costs of traveling wherever the service is available. Still, tempting.
@@SpaceMog it's worth every second of it, highly recommend it.
When you are near a glider field where they do aerobatics you can experience parabolic flights or turns.
Ok, because of the limited speed of gliders, Something between 240km/h to 300km/h the energy aviable is limited so the time of weightlessness. But for a few seconds you can experience it. And it is not expensive and mostly in a reachable distance.
Here is a video of one of my flights where I did two turns. In the first one you see the dirt flying through the cockpit during weightlessness.

But yeah, the time is limited. But you can do a lot turns out of 3000ft agl... 😬
My fave is The Vomit-Comet😂
It's no longer called this which used to refer to the American plane, the European plane is nicknamed the flying lab and actually very few people get sick on it.
excellent video, very well presnted 💯
Thank you!
Thanks so much for creating and sharing this informative video. Great job. Keep it up. 😻
jumping on a trampoline, sky diving, clif diving are good simple and cheap ways of finding out what 0G is like. You can also get a short time in 0G in a private plane. Take a look at the zero g dog.
Skydiving? Nope! When you get out of the plane you will do it at a speed of 70 kts or higher. The King Air you will leave at 90 kts. At that speeds you jump directly into the wind and you will lying on the
wind decelarting you horizontal, so there is no feeling of wheigtlessnes.
If you want to be weightlessnes during skydiving you have to do it out of a balloon. With zero speed. But this is a very rare opportunity.
And believe me, I have a lot skydives...
@@MisterIvyMike I have jumped 5 times from a Cesna 172. And I can tell you that the first instant you step off the step, you feel weightless. (ignoring the wind. You can be weightless and still have lots of wind.) It's a subjective thing.
I've never had one free fall dive :( . Every one was with a static line. I'm thinking about it though. I'll probably just rent my gear until I'm certified for the 10K' jump. $250 for one jump.... too steep for a hobby. And I might not really like it anyway.
@@KaiseruSoze Ok, yeah, its a subjective thing, thats right.
The first seconds maybe you feel a bit lighter.
After a few hundred skydives I only enjoy the exit, "freefall" is not really free falling because when you reached your final velocity you lay flat on the relativ wind, not further accelerating.
Nowadays I fly gliders in a club and did my glider aerobatic licence and now I'm able to feel the forces from negative G's, weightlessness and a lot positive G's. In a glider you have these negative or positive G's not for a long time, because the only energy you have is your airspeed. But it is funny as heck!
This is relatively affordable when you fly in a club with a Ask-21 or a similar plane.
Can Dr Lieu's facility duplicate the double headed c elegans results? Probably good for a paper. How about testing pharmaceutical production? Costs are crashing with SpaceX though scheduling is still difficult. Maybe run a proof of concept in Dr Lieu's lab before scheduling, waiting for, a full run on ISS or its successors. Developing the techniques for production in Dr Lieu's lab would be good for some papers too.🙂
First time hearing of the double headed C. Elegans, but to be honest, im convinced many of them are double headed with their movements! It has hard to even make the training data for the machine learning too track them! Thanks for the ideas!

Hello Space Mog
Pleased to meet you :)
Hi :-)
where did you get this "need more space t-shirt"? 🙂
it was a gift :-)
👍👍👍
Hello, I am new in your channel, it seems very interesting to me, gravity is a misterious force but antigravity is more misterious, I did an experiment and could create a gravity wave but it lates only microseconds, I want to create a device to cancentrate and amplify this wave, may be I achieve it some day. you are great and wonderfull lady go ahead!!!
back in my day they trained us to eat hotdogs on roller coasters
No way! I may have to try that one... but if ketchup and mustard is involved things may get sticky 🤔
Don't think he was training for what you think
I've been doing it for years using vodka and willpower alone
That's my favourite method too
it would be so cool if you could simulate a big enough area for a person to experience weightlessness for as much time as needed for experiments or training. Do you think we are getting closer to building something like that??
unfortunately the only way to experience it for long periods is in orbit around a celestial body.
As I get older, my perception of time speeds up, so should that not reduce my mass? Or, my perception of gravity?
Maybe you create your own bigger gravity field (Like I do. I get fatter and fatter) and now the time goes faster in your own greater gravity field... 🤔
what are those things on your eyes?
What is that?
Are those brushes?
find an elevator that goes down 10m per second, good luck!
And then? You have to accelerate 10m per second, not only going down with 10m per second...
A massive drop tower!
Congrats on your first 100k+ viewed video (on Bennu).💖😻🥰🌠
There should be a J-shaped drop tower (transparent tube) so humans could have a cheaper microgravity ride for fun. Maybe a mineshaft could be modified somewhere for an amazing longer J ride.😅 I think a float tank, sensory/isolation relaxation tank, would be ideal to rejuvenate in simulated microgravity most every day for whatever length of time you wish to enjoy it w/music or VR or ?🥰
you must hear this everyday but you are so stunning. Such a beautiful smart young women.
You're my favorite. I wish we could just get married and you can be a US citizen. LU other version of WE...💚💜
let's all float in space and dream about the universe and all its colors .Who wanna go ?🙂🙃🙂😍miauuuu😻💫
me 😃
Once again thank you for giving wonderful knowledge❤, it is also a fact that my day becomes better with your videos. I know that you are so Busy with your profession but Please tell me what's going on in your mind about your channel because without research and procedure nothing can happen even in the astronomy. Am I right? My Captain!🤠 I'm eagerly waiting to share my designed thumbnail, script ideas, Algorithmic codes of youtube know them and just apply them and observe the boost. and thanks that you replied me it means a lot to me!💯
