In the third century BCE, King Hiero II of Syracuse asked Archimedes to devise a number of death traps to thwart Roman invaders. Among the many designs the great inventor drew up was a solar death ray. The basic idea was to build an array of mirrors that could reflect rays of light into a central blast, causing Roman ships to burst into flame. It’s unlikely the weapon ever made it past the blueprint stage, but it became an incredibly influential model nonetheless. Archimedes was perhaps the first solar power convert, searching for a way to take advantage of the inconceivable amount of energy our friendly neighborhood star barfs up every second.

The only thing that would make Archimedes’ solar death ray more fascinating is if it was technically feasible, socially benevolent, and in space. That’s where John Mankins comes in. A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, Mankins designed the world’s first practical orbital solar plant. It’s called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines.

Scientists have been aware of the edge the “space-down” approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun’s inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy.

2015 was literally and figuratively the year of the hoverboard. While everyone was talking about the self-balancing scooters, two companies showed off skateboard-shaped boards that actually hovered a few inches above the Earth: Lexus with the “Slide” board, and Arx Pax with its second generation Hendo Hoverboard. Now, just days before the new year, another company called ArcaSpace is taking a shot at making the mythical hoverboard.

ArcaSpace is primarily a private space company, and one of the original 26 teams that competed in the Ansari X Prize competition in 2004. (It also entered the Lunar X Prize competition, too, before pulling out in 2013.) But early this morning the company released a video that shows off the “ArcaBoard,” a fan-powered rectangle that can lift a person off the ground by almost a foot.

The ArcaBoard gets its power — 430 pounds of thrust, or 272 horsepower, according to the company — from 36 electric fans. The company also says its built in some self-balancing tech to make it fly smoothly. Beyond that, though, it doesn’t look like there’s much to the experience. Dumitru Propescu, ArcaSpace’s CEO, is seen riding it in the video, but it doesn’t look like he has much control over where it’s going. It’s actually pretty reminiscent of the Hendo Hoverboard videos — sure, it hovers, but you can’t really steer it enough to ever use it to get anywhere.

How an innocent plea for collegial comments turned into a global news flap about a possible Super-Earth on our solar system’s outer fringes.

The odds that our solar system harbors a super-Earth on its outer fringes are longer than the chances of winning a state lottery (or at least 200 million to one), says a University of Hawaii planetary scientist. In fact, the recent news flap over the potential detection of a rocky planet in a very long solar orbit was greatly exaggerated, the lead author of the scientific paper which resulted in the controversy now says.

“We never claim a super-Earth; we state it can’t necessarily be ruled out on the basis of our data alone, but the much more likely explanation is a much more nearby icy-body,” Wouter Vlemmings, a radio and submillimeter astronomer at Sweden’s Chalmers University of Technology, told me.

While the science and technologies behind the franchise are firmly rooted in fantasy, their enduring appeal has served as inspiration for many real-life scientists and engineers. Here are some of the most notable attempts to turn “Star Wars’” science fiction into science fact.

China wants to be the leading force in manned space exploration, and is exploring sending people to the far side of the moon, Mars, asteroids, and further into deep space.

Becoming the second largest economy in the world and an emerging superpower of its own, China wishes to add deep space exploration into its achievement portfolio. Besides the ongoing moon exploration, its scientists are considering going deeper into the solar system, including Mars, asteroids, and even manned deep-space mission. Liu Jizhong, director of the lunar exploration program and space engineering center, pointed out that China has to be more pioneering, tackling problems such as high speed deep space exploration, energy and power generation, space robot development, and more. He also said that China must cooperate with others as space exploration is an undertaking shared by the entire human species.

China currently intends to explore the far side of the moon, something that has never been done before. It would require a relay satellite for communication and navigation on Lagrange point, where the satellite could orbit within the combined gravitational pull of the Earth-moon system, as said by Zhang Lihua of China Spacesat Co. While China believes that robots are critical to the mission, it also believes that these trips must be manned in order to effectively leverage human decision-making. China also says they are designing footed robots to explore asteroids and better understand their material composition.
