Greenhouse Experiment on ISS
Paolo Nespoli, unfortunately has had to terminate his education experiment Greenhouse in Space due to the fact he noticed some fungus growing beside one of the plants. In this video, he takes great care to explain exactly what
has happened and shows us all the procedures that are necessary on the ISS to maintain a safe environment. Although Paolo managed to grow some healthy plants in one of his greenhouses, no risks can be taken.
Paolo encourages all the children participating in the Greenhouse experiment to carry on trying to grow Arabidopsis from seed to seed as this is important for the future of long duration and distance space travel.
That's an excessive amount of trash.
Could it be because there is no sunlight? Might that be the reason that the seeds won't grow?
I wanna se footage of plants growing and animals in space!
they go off of Greenwich mean time not American or Russian so my guess is Russia and greenwich
GMT (since this is the time kept on ISS) and probably the time where his family are living. Sometimes the astronauts also wear watches that are part of one of the ISS experiments – a heartrate monitor for example.
why plant greenhouse are toxic space station?
Guys, this astronaut is Italian, not Russian!
Paolo Nespoli will fly to ISS again on 30 May 2017, as a part of Expedition 52/53.

Recreating gravity in space is no new idea, though its pretty hard to do this when it comes to living and moving things.
As you may have watched the movie 'Interstellar' they tried to improvise gravity there by using centrifugal forces to 'press' the crew against the floor. For that they built a spaceshuttle similiar to a ring and gave it a spin.
The problem with this is simply that it would only work if all the mass of the spaceshuttle is equally distributed from the center of rotation.
Try this:
Get one boiled and one raw egg.
If you gonna give a spin to those eggs they will automaticly try to rotate around their center of mass.
The boiled egg (with 'nearly' equal distributed mass viewed from its center) will rotate steady around this axis.
Though the raw egg is still liquid inside. That means that the center of mass is moving around (because of the yolk): The egg wont rotate steady.
Now think of a space shuttle. If it spins and some member of the crew moves around – the distribution of the mass changes and with it the center of rotation. So for every movement you're doing – even putting a pencil from one spot to another – must be compensated by other masses. Else you would get an unsteady spin. That this is a problem is another category but trust me – it is a big problem.
Beside this there are a lot of other problems. For example is the centrifugal force of such a small rotating system not equal on your whole body. Your head would get pulled down less strong than your feet.
Right now (and afaik) there is no other way to recreate such a force in space.
Cant you just fly a green house to space
If there's a possibility of an airborne threat which he's protecting himself from then why the hell there's no such protection for the whole station and other crew members… What kind of safety regulations is this ..
wow
I would love it was made more experiments shows on the ISS and one would be two strings with both balls attached each side being throw rotating to check if they stay together in the centre axis…. For example…
The Real Question Is, Do You Think The Fungus is Necessary For Growth?
Why he killed the plants?
