15 Most Unusual Flying Vehicles That Will Change The World!
We have all seen planes, helicopters and jets. But is the world of flying vehicles about the change? Are we about to witness the biggest innovation in flight since the Wright Brothers? Be it thanks to the latest and greatest leaps in technology, or due to the madcap ideas that come out of the Red Bull Flugtag, people have been attempting to pioneer the art of flight. These are the most unusual flying vehicles that will change the world!

Pushing the Envelope: The Art and Science of Ballooning — STEM in 30
There’s more to balloons than birthday parties! Hot air balloons changed the world centuries ago, and they continue to teach us a lot about science. Learn about the art and science of ballooning from Air and Space experts and ABC’s chief meteorologist Ginger Zee in this episode of STEM in 30.

Mars is our next door neighbor, yet we almost never visit. But in July of 2020 humans are launching four separate missions to Mars.

The missions are all launching in July 2020 because it is the ideal time to get a spacecraft to Mars while using the least amount of rocket fuel.
But not because the two planets are at their closest, instead it has to do with something called a Hohmann transfer orbit—the most efficient way to send a spacecraft to Mars.
This orbit is elliptical, and uses the sun as one focal point. The spacecraft’s launch is at the closest point to the sun, or perihelion, and it crosses Mars’ path at its farthest point from the sun, or aphelion. It is very important that Mars is actually there when the spacecraft arrives, but for that to happen the spacecraft has to be launched at just the right time.
The time it takes a spacecraft to travel from perihelion to its aphelion in Mars’ orbit is approximately 259 days. During that time Mars will move about 136 degrees, since Mars is farther from the sun than Earth and takes longer to move the same angular distance.
So in order to sync up the 180 degrees the spacecraft will travel while Mars moves 136 degrees, the spacecraft needs to launch when Mars has a 44 degree head start. This happens for a few weeks once every 26 months, and the next time it will happen is mid-July of 2020.
And so, this time around a lot of space agencies are geared up for launch.
Find out more about all the July 2020 missions to the Red Planet in this Elements.

«If there is a story of life on Mars, there may also be a story of death — the catastrophic loss of an atmosphere, and potentially with it, a temperate environment and liquid water. 'The big question is, why did Mars go from being warm and wet to cold and dry,' says Weiss, a planetary geophysicist. 'One of the leading ideas is that it lost its atmosphere.'»
