2016 HO3

Scientists recently discovered a small asteroid, dubbed 2016 HO3, that orbits the Sun, but also stays between 9 million and 24 million miles of Earth at all times.

It could be the ideal target for NASA's manned mission to an asteroid.

Mars Helicopter

NASA is considering sending a small helicopter to Mars with its next rover in 2020.

The solar-powered aircraft, which would essentially be a technology demonstrator, would scout ahead of the rover, helping to map out the best routes.

Luxembourg

The government of Luxembourg is partnering with Planetary Resources to advance the asteroid mining industry.

Luxembourg may even take a minority stake in PR.

Primordial Black Holes

Tiny primordial black holes-- black holes that formed soon after the Big Bang-- may make up so-called dark matter, a new theory suggests.

So, dark matter may not be fundamentally different, after all.

Relaunch

SpaceX is looking at relaunching a booster in September or October, according to Elon Musk.

If successful, such a relaunch would be a big step towards establishing the viability of reusable rockets.

China's Moon

China's next lunar mission will reportedly include a far side landing.

The mission will study, among other things, the structure of lunar dust.

Extending Dawn

NASA is considering sending the Dawn spacecraft, which has visited Vesta and is currently orbiting Ceres, to a third asteroid.

Dawn's revolutionary ion propulsion system is in better shape than expected, allowing a possible extended mission.
