Solar power: the final frontier.

As a power source, solar power is truly universal. The same solution that powers our homes and businesses can be used to power habitats and batteries on Mars. Here are some of the best inventions to help us explore beyond our home planet.

Solar power is often thought of as a utility: a solution to a power problem. In the past, we’ve spoken about how solar power can be a great way to save on your energy bills, but in the future it could also be the primary source of life-sustaining power on other planets.

The problem identified by NASA is that traditional fuel sources aren’t sustainable in space and need to be resupplied on Earth (it’s a struggle to cart thousands of tonnes of coal to new human colonies). So to keep habitats and rockets humming along, we need something that will power a planet, wherever it may be. The solution is solar power.

The same solar panels you have on your roof are being used in space to keep vital machines running and help us explore other planets. The plans for solar power span from engines to homes with oxygen generators.

The International Space Station is already powered by solar, along with the batteries that keep the Opportunity and Spirit Rovers moving.
