Let’s be honest, launching things into space with rockets is a pretty inefficient way to do things. Not only are rockets expensive to build, they also need a ton of fuel in order to achieve escape velocity. And while the costs of individual launches are being reduced thanks to concepts like reusable rockets and space…

In the coming decades, NASA and other space agencies hope to mount some ambitious missions to other planets in our Solar System. In addition to studying Mars and the outer Solar System in greater detail, NASA intends to send a mission to Venus to learn more about the planet’s past. This will include studying Venus’…

After almost 70 years of spaceflight, space debris has become a rather serious problem. This junk, which floats around in low Earth orbit (LEO), consists of the spent first rocket stages and non-functioning satellites and poses a major threat to long-term missions like the International Space Station and future space launches. And according to numbers…

In its pursuit of missions that will take us back to the moon, to Mars, and beyond, NASA has been exploring a number of next-generation propulsion concepts. Whereas existing concepts have their advantages – chemical rockets have high energy density and ion engines are very fuel-efficient – our hopes for the future hinge on us…

In 2015, Russian billionaire Yuri Milner established Breakthrough Initiatives, a non-profit organization dedicated to enhancing the search for extraterrestrial intelligence (SETI). In April of the following year, he and the organization be founded announced the creation of Breakthrough Starshot, a program to create a lightsail-driven “wafercraft” that would make the journey to the nearest star…

SpaceX and Tesla-founder Elon Musk has made some rather bold promises over the years. In addition to building a fleet of reusable rockets, an Interplanetary Transport System, colonizing Mars, and revolutionizing transportation, he has also made it clear that he hopes to provide worldwide broadband access by deploying a “constellation” of internet-providing satellites. In November…

With its dense and hydrocarbon-rich atmosphere, Titan has been a subject of interest for many decades. And with the success of the Cassini-Huygens mission, which began exploring Saturn and its system of moons back in 2004, there are many proposals on the table for follow-up missions that would explore the surface of Titan and its…

Founded in 2009, the private aerospace company Zero2Infinity – which is headquartered in Barcelona, Spain – was created with the vision of delivering orbital payloads and providing space tourism on a budget. But unlike your conventional aerospace companies – i.e. SpaceX, Blue Origin, Orbital ATK, etc – their plan is to do it all using…

It’s always a welcome thing to learn that ideas that are commonplace in science fiction have a basis in science fact. Cryogenic freezers, laser guns, robots, silicate implants… and let’s not forget the warp drive! Believe it or not, this concept – alternately known as FTL (Faster-Than-Light) travel, Hyperspace, Lightspeed, etc. – actually has one…

Oklahoma’s Beaver River is an incredibly historic place. Anthropologists estimate that as early as 10,500 years ago, human beings hunted bison in the region. Being without horses, the hunter-gatherers would funnel herds into narrow, dead-end gullies cut into the hillside by the river. Once there, they would kill them en masse, taking the meat and…
