Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.
Liftoff to the distant asteroid is scheduled for Oct. 5, 2023 – the beginning of a six-year journey to one of the most unusual objects in the solar system.
Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.

Of all the planets in the solar system, there’s a reason we call Earth home. It’s made of just the right stuff. It’s not too small, or too big, or too hot or too cold. It’s just right.
Fossil fuels are heating the atmosphere – but the fact that we’re burning them may not be the only reason.
Material from the Earth’s core has been leaking into the mantle through activity that led to volcanic eruptions such as that helped form the Hawaiian islands.
