NASA Launches First Robotic Archaeologist Lucy to Study Trojan Asteroids

NASA never stops to amaze us with its super-scientific cards under its sleeve. This time, NASA has launched its newest asteroid probing spacecraft, named Lucy, on a super-ambitious space journey. The initiative is designed to get better knowledge about the final unexplored regions of asteroids within the whole solar system.

The Mission

Launched from the Kennedy Space Center in Florida, Lucy is set to embark on a 12 years-long mission to study Trojans, which are two different swarms of asteroids around the orbit of Jupiter. Working like a robotic archaeologist, Lucy will help the scientists learn about the initial formation of the giant planet. It will visit through eight asteroids altogether.

The Spacecraft

Sized like a refrigerator, Lucy lit up the sky above Cape Canaveral during its launch. A United Launch Alliance (ULA) Atlas V rocket was used to perch the spacecraft on top during launching. It leaped off its launch pad exactly at 5:34 AM EDT (0934 GMT) on October 16, Saturday. By two hours after the successful launch, NASA confirmed the successful deployment of Lucy’s solar arrays in the destination.

The Process

For the coming six years, Lucy will travel through the solar system, circling Earth, twice. This is essential for building up the necessary momentum to reach Jupiter. Among the eight different asteroids, the spacecraft will cover, seven are Trojans located in two separate clusters. One cluster is located ahead of Jupiter and its orbit, and the other is behind. One single asteroid is placed on the main belt of the massive planet.

The Asteroids

According to the researchers, Asteroids are scientifically important, because they are essentially leftovers from the initialization of the solar system. Being perfectly preserved cosmic time capsules, these Trojans can be highly helpful to shed more light on the origin of the solar system along with its giant planets, if studied properly. With the help of a number of scientific instruments, Lucy will thoroughly study the structure, composition, density, and geology of each of the eight asteroids.

Engineers Have Made A Real-Life Lightsaber That Can Cut Through Steel

Are we living in a sci-fi movie? It certainly feels like it sometimes. If you have ever dreamed of owning a real-life lightsaber, then it looks like you’re about to be in luck thanks to the engineers from the Hacksmith on YouTube.

Hacksmith Industries

If you’ve never heard of the Hacksmith channel, then you’re going to want to subscribe straight away. This team of engineers take fictional ideas from comics, movies, TV shows, and video games, and turn them into working prototypes. From Captain America’s electromagnetic shield through to the Kingsman umbrella, these guys have made some seriously cool things over the years.

The Lightsaber

However, one of the most iconic engineering feats from any movie has to be the lightsaber – and these guys have finally created a fully working one. It retracts, changes color, and even cuts through steel like it’s butter. Powered by plasma, their saber burns at an incredible 2,200°C (4,000°F) and looks just like a real lightsaber. In their YouTube video, the Hacksmith engineers show just how powerful it really is.


Technically, as there is no tiny infinite energy source within the handle of this lightsaber, this is a protosaber. It relies on an external power pack that shoots plasma out of the handle just like in the Star Wars movies. This technology is mainly used for glass blowing currently, so it only makes sense that a lightsaber was the next logical step. Different salts in the plasma also ensure it glows green, orange or red – so you can pick your side!

James Hobson, lead engineer on the project, admits there are very few people working on lightsaber technology right now (unfortunately) so it means this will have to fill the gap until someone comes up with something else. Potentially something a little safer, and a little less burning hot.
