For thousands of years we have been looking at space exploration but are we spending to much time on it?
As you may have heard in your previous lessons scientists have invented many pieces of equipment for space exploration but as we all know they cost a fair amount. Some of which are really important to space life e.g...
- water purification
- artificial limbs
- foil blankets
- Dust Busters
And many others.
The situation on earth is just as crucial as space. Do we need to spend more time on Earth?
As you all know Earth is not perfect with a lot of things to be done. Scientists are looking at things that may help in the future such as..
- A virtial telescope the size of Earth.
- Pills for loneliness
- Flying cars
- Understanding the complex of earths systems
And a whole lot more on https://futureearth.org/
As previously mentioned in lessons, space spends tons of money on equipment and reasources. ISS-The International Space Station- is the most expensive man-made object ever built! Costing $160 billion dollars! The space station has been continuously occupied since November 2000 as an international crew of six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes. Suprisingly, in 24 hours the space station makes approximately 16 orbits of Earth.
We know so much about space. Is it time to focus on Earth?
