From the dawn of the space race to an era of international cooperation, the exploration of outer space has pushed both the limits of human imagination and humankind's technological capability. Explore the rich history of space exploration below, along with where we may go in the future.
Hours of research by our editors, distilled into minutes of clarity.
Lagrange Points are special locations where gravitational forces let spacecraft "park" without constant course corrections, making them ideal for science missions. NASA’s James Webb Telescope uses Lagrange Point 2 to stay aligned with Earth while orbiting the Sun.
On March 2, 2025, Firefly Aerospace landed its Blue Ghost craft on the Moon. The private company then operated the craft for two weeks, conducting surface operations and becoming the first private space company to have a fully successful mission on the Moon. This short video captures pristine, dramatic footage of the mission's successful touchdown.
Take one small step today and experience the historic moon-landing through VR. This video showcases how VR is allowing the public to travel through space through the eyes of those who lived through it.
The history of animals in space exploration is often overlooked. Before humans first made their way to space in 1961, fruit flies, primates, and canines preceded us. Watch this video for a further appreciation of the contributions and sacrifices made by animals for scientific progress.
How do rockets work? What is the science behind a rocket launch? How does a rocket go into space? In this short and simple video, we discuss the science of rocket propulsion and what takes to get these vehicles into orbit.
Let us to take you back through the timeline of space exploration and its rich, fascinating history, starting in 1946, with a rudimentary German military rocket.
Mars remains the most viable interplanetary destination due to its relatively habitable orbit. There are many challenges, however, including the huge distance to Mars, the need for advanced propulsion systems, uncertainty over the impacts of long-duration space travel on astronauts, and the need for safe landing techniques and equipment to handle Martian conditions. Human-manned missions to Mars are not likely to occur until the 2030s at the earliest.
Astronomy is the only science that is purely observational: meaning, scientists can't study stars in a lab. Here's a breakdown of how modern researchers use new tools to understand objects billions of light years away. As it turns out, the rules of science allow us to identify, categorize, and experiment with phenomena light years away.
SpaceX has single-handedly reignited commercial space exploration, with its reusable rockets, broadband satellite constellation, and plans to populate Mars. The company has gone from a mere idea in 2002 to the world's most well-known private space company. Learn the basics about this pivotal company with this quick guide from CNET.
Because conditions on Mars are pretty extreme for humanity, we tend not to think about living there, since everywhere on Mars feels a bit threatening. This imaginative essay uses current geographical knowledge of Mars to visualize what it would look like if humanity could alter its climate to make it widely habitable, a process known to sci-fi readers as terraforming. Given that transformation, where would the hottest neighborhoods be located?
From roughly 60 miles above the Earth's surface to farther than light has traveled during the entire age of the universe, space has captured human imagination for millennia. Explore the final frontier with the best resources curated from across the internet.
