A few weeks ago, a team of scientists from Caltech announced that they had successfully
transmitted energy from an orbiting satellite down to Earth. It wasn’t a lot of energy, but it showed that it was possible.
Eventually, we might be able to beam energy from solar satellites down to Earth, making solar energy available almost anywhere and helping combat climate change. But there’s another potential use: powering surface probes on Venus.

The ARIEL mission is a space telescope that will examine the atmospheres of at least 1000 exoplanets. Image Credit: ESA
We found our first exoplanets orbiting a pulsar in 1992. Since then, we’ve discovered many thousands more. Those were the first steps in identifying other worlds that could harbour life.
Now planetary scientists want to take the next step: studying exoplanet atmospheres.
The ESA’s ARIEL mission will be a powerful tool.

The Solar System’s moons are intriguing objects for exploration. Especially moons like Europa and Enceladus. Their subsurface oceans make them primary targets in the search for life.
But why not send one spacecraft to visit several moons? NASA’s about to launch its
Lucy mission which will visit 8 separate asteroids. Could the same be done for a mission to multiple moons?
For a spacecraft to do that, it would have to do a little dance with the notorious three-body problem, which makes a stubborn partner. A new study presents a possible way to do that.
