MOONSHOTS
the launching of a spacecraft to the moon.
The moonshot is much more challenging in these ways:
No-one can succeed alone.
Actually, the moonshot calls for several, independent parts to succeed.
On top of this, the co-operation between the independent parts also have to succeed.
To make all this come true, everybody has to share the vision - to long for the moon
Earth and the moon are so similar in composition, researchers have concluded that the impact must have occurred about 95 million years after the formation of the solar system, give or take 32 million years. (The solar system is roughly 4.6 billion years old.).
The moon very likely has a very small corejust 1 to 2 percent of the moon's mass and roughly 420 miles (680 km) wide. It likely consists mostly of iron, but may also contain large amounts of sulfur and other elements.

Its rocky mantle is about 825 miles (1,330 km) thick and made up of dense rocks rich in iron and magnesium. Magmas in the mantle made their way to the surface in the past and erupted volcanically for more than a billion years — from at least four billion years ago to fewer than three billion years past.

The crust on top averages some 42 miles (70 km) deep. The outermost part of the crust is broken and jumbled due to all the large impacts it has received, a shattered zone that gives way to intact material below a depth of about 6 miles (9.6 km).
The tilt of Earth's axis is about 23.5 degrees, but the tilt of the moon's axis is only about 1.5 degrees. As such, the moon virtually has no seasons. This means that some areas are always lit by sunlight, and other places are perpetually draped in shadow
.A halfway-to-the-moonshot: consider the space elevator, a concept over a century old which, if executed, would allow remarkably affordable transportation back-and-forth into Earth orbit. Famously depicted by science fiction authors such as Arthur C. Clarke and Kim Stanley Robinson, is it something we could see built in our lifetimes? Research how a space elevator would work,
Building on ideas first proposed by Nikola Tesla in 1891, scientists and private ventures in the 21st century are finally trying to make wireless electricity an everyday reality.
Woolly mammoths, dodos, and various recent CGIosauruses: one modern-day moonshot suggests we could revive long-gone species, provided we can find well-preserved samples of their DNA.
Is landing among the stars good enough? In his final year in office, and motivated in part by the death of his vice president's son, President Obama announced a moonshot to cure cancer—a moonshot that has inspired some controversy. Consider the argument made in this article for why some moonshots succeed, and what it implies for the cancer moonshot and others. Be sure to research the basic science behind promising new cancer treatments, such as those based on immunotherapy.

We look for a huge problem in the world that affects many millions of people. ­
Then we try to propose a radical solution for solving that huge problem ­
And third, there needs to be some reason to believe that the technology for such a radical solution could actually be built. Some glimmer of hope to get us going and some clear first few steps we could take along that journey.
Last year we killed a project in automated vertical farming. This image above shows some of the lettuce we grew. 1 in 9 people on the planet suffer from undernourishment so the need for a moonshot is clear. Vertical farming uses 10 times less water and 100 times less land than conventional methods, and you can grow food close to where it’s consumed, so you don’t have to transport it long distances. We made progress on many of the issues like automated harvesting and efficient lighting but in the end we couldn’t get staple crops like grains and rice to grow this way, so we killed the project. If someone comes up with a dwarf species of rice, let us know — because that might crack the puzzle!
With 1.2 million people dying on the roads globally each year, making cars that drive themselves was a natural moonshot to take. Three years ago, our retrofitted Lexus self­-driving cars were doing so well in testing that we loaned them out to other Googlers, to see what they thought of the experience.
