ISS HD Earth Viewing Experiment.

I’ve always found that because of the monopoly of some websites, the internet is for a lot of people I know, limited, mainly to  Facebook. It’s like swimming in a little part of some big swimming pool.

I am often amazed by the internet.

What if you saw earth from space ? Simple, you can do it on the internet, but I am not talking about Google Earth. You can actually watch the Blue Planet from space, Live, with cameras mounted on the ISS, the International Space Station ( yup people are constantly above our heads )

As I speak, its altitude is 434km, and it is traveling with a speed of approximately 27,000 km/h.

Here’s the description of the mission on Nasa’s website :

Description

The High Definition Earth Viewing HDEV primary objective is to validate the space-based performance of the cameras in a variety of operating modes to exercise and demonstrate the features and longevity of the COTS equipment for future ISS Program usage. This payload is an external earth viewing multiple camera system using a set of Commercial-off-the-shelf (COTS) cameras. The HDEV integrated assembly is composed of a camera system of four COTS cameras, integrated Command and Data Handling (C&DH) avionics (ethernet), and a power data distribution box that allows the integration of the payload’s components interface to the ISS Columbus module.

The HDEV visible HD video cameras are a fixed payload camera system that requires no zoom, no pan or tilt mechanisms. The four fixed cameras are positioned to capture imagery of the Earth’s surface and its limb as seen from the ISS (i.e., one camera forward pointed into the station’s velocity vector, two cameras aft (wake), and the other one camera pointing nadir).  The video imagery is encoded into an Ethernet compatible format for transmission to the ground and further distribution.  In this format, the video can be viewed from any computer connected to the internet.

 

This website also give the current position of the ISS, when it is on the night side of the earth, the image is well, black.

The images are amazing.

Live streaming in Lebanon and in HD, is quite expensive, and you must have a good internet speed. But it is really worth the try. 5 minutes of this and you will be in awe.

I wish Lebanon was sending men to space, I would have been the first one in line.

 

 

Science Revolution.

Scientific inventions that we hear about and consume, don’t lead to much, a new device like the iPad won’t save the humanity, a new and small camera sensor and more pixels in it won’t resolve the poverty or save refugees. Well you got the point, often new inventions in technology etc in my point of view, are not made to improve the society as a whole, and when I say improving the society, I mean fighting inequality, injustice, and helping these people that you try to ignore. No, your iPhone 5S won’t improve it.

Of course, pharmaceutical research help improving humanity, eliminating ugly incurables diseases, and I can think of a lot of fields other than pharmaceutics.

But that’s not the point of this post, I just wanted to show something that I find amazing, that can change the life of millions if not billions. It’s called the Ultra-Ever Dry, it’s a super-hydrophobic ( that is “scared” of water ) coating and it repels almost any liquid.

Here’s the few applications I think of :

Car : apply the coat on the glasses of your car, rear and front, and forget about the annoying windscreen wipers. Rain will alone remove itself…

Buildings : same category, glass, no more rain on them, dirt can be repelled maybe. And for the architecture, imagine if this invention will kill moisture, that make fall whole structures.

Refugees tents : imagine this repellent on the tents roofs, water don’t get in, and refugees don’t get wet.

Cloth : no more wet clothes and this annoying cold you catch after.

The list I think of is veryyy long. Let’s hope the inventors of this product will use it to make the world a little better.
