This ISS live stream of planet earth from space is courtesy of Nasa Earth Viewing Cameras aboard the international space station.
The station is crewed by #NASA astronauts as well as Russian Cosmonauts and a mixture of Japanese, Canadian and European astronauts as well.

The Expedition 62 Crew is: Christina Koch, Andrew Morgan, Oleg Skripochka

THIS WILL SHOW LIVE and PRE-RECORDED FOOTAGE -
As the Space Station passes into a period of night every 45 mins video is unavailable - during this time, and other breaks in transmission, recorded footage is shown .
When back in daylight the live stream of earth will recommence

If you are here to talk about a flat earth then please don't bother. You can stay and watch our beautiful globe earth as it spins in space , but please don't share your nonsense beliefs in our chat.

Launching Americans from U.S. soil, sending a new rover to Mars and continuing to prepare for human missions to the Moon are just a few of the things NASA has planned for 2020.

Pioneering NASA mathematician Katherine Johnson has died at the age of 101. Johnson was part of a group of African-American women who worked on critical mathematical calculations in the early days of human spaceflight, as chronicled in the best-selling book and hit movie “Hidden Figures.”

"She was an American hero and her pioneering legacy will never be forgotten,” said NASA Administrator Jim Bridenstine.

A short a cappella tribute to experimentalists. It is sung while performing three simple experiments with household items: Mentos dropped in diet Coke, a tea bag emptied and burned, and a ping pong ball floating in the air stream of a hair dryer.

When the rope becomes taut, the force on the jumper is mainly his weight downwards, plus a bit of air resistance up. Therefore his speed is increasing nearly as much as it did when he leapt off the platform. So this is not the greatest acceleration of the jump.

Two 1.5kg masses are released simultaneously from the top of a 10m high wall. One is attached to a chain while the other is free. Which one will hit the ground first?

On the rebound, the acceleration varies. The jumper is accelerating up but as the bungy recoils, the jumper starts accelerating down again due to the pull of gravity. This does not mean that he's moving down, however, only that his velocity upwards is decreasing.

Right after leaving the platform, the only significant force acting on the bungy jumper is his weight. This causes him to speed up from rest. His speed increases every second by nearly 10 m/s. This is not the maximum acceleration experienced by a bungy jumper, however.

It's the most abundant liquid on the planet and by weight we are about 60% water. But do we know what it is made of?

I saw my first wild koalas while driving on the great ocean road. Generally their days are not very exciting. They spend most of their time sleeping and the rest of the time eating eucalyptus leaves. The eucalyptus leaves are tough to digest which explains their consumate napping. Plus they require bacteria in their gut to help them break down their food. This bacteria must be passed down from mother to child through the mother's poo. It's a tough start to life for koalas!

Why we can't seem to agree on what's true when it's easier than ever to check.

http://www.youtube.com/spacelab gives you an opportunity to design an experiment to be performed in space! If you're between the ages of 14-18, make a 2 minute youtube video proposing an experiment to be performed in zero g. Your video will be assessed by a panel of experts with the winner having their experiment performed in space and broadcast live to the world.

At the jumper's fastest point, the acceleration is by definition zero. That is because the jumper is going from speeding up to slowing down. At this instant then there is no change in the jumper's velocity. This is counter-intuitive for a lot of people because it's easy to confuse velocity with acceleration. Velocity is how fast something goes while acceleration is the rate at which velocity changes.

The solution to the question posed in the spinning tube trick video, that is - what would you see if looking at the spinning tube from below a glass table. The explanation of why only the X or O is visible will be the subject of the next video.

If the sun were entirely made of protons, how many would there be in the sun? How can this be worked out using the Google search field?

2011 is the international year of Chemistry. But what do Australians know about it?

Electric cars are now ready to take over thanks to advances in battery technology and their inherent benefits: torque, handling, maintenance. This video was sponsored by BMW: https://www.bmwusa.com/

Full disclosure: I drive an #electric #car. I think electric cars are the future, not mainly because they're better for the environment (which they are if you drive the car for any reasonable length of time) but because they are just better cars. The have better torque and acceleration, better handling, they're more efficient, quieter, they don't smell, they're cheaper to run and best of all you never have to visit a gas station - this appeals to me. I never have to worry about being low on gas because every morning my car is charged and ready to go - just like my phone and laptop. And if you're worried about range, don't. Almost all trips can already be done in an electric car with modest battery pack. And fast chargers along the way make it possible to do longer road trips if necessary. You have to make rest stops anyway, just time them with the charging. And consider that battery tech is getting dramatically cheaper, smaller, lighter. All these reasons are why I see the #future of cars as electric.
