Late January and early February are the anniversaries of two of the most disastrous events in the history of spaceflight. What did we learn from these events, and how do we move forward?

The ESA is working on a 'fresh-squeezed' spacecraft that will explore Jupiter's moons, and the New Horizons team makes a case for Pluto (and many others)!

Imagine going about your life knowing that, at any given moment, you and everyone you know could be wiped out without warning at the push of a button. This was the reality for millions of people during the forty-five year period after...

Hank updates us on two new missions that will help us learn more about some of the fascinating things in our space neighborhood.

Rockets are super amazing, but how do we get something that weighs as much as 100 elephants all the way into space?

Learn about how one Japanese startup wants to offer meteor showers on demand, and how this will affect our scientific study of the mesosphere.

A new crew is headed to the ISS, and Pluto seems to have methane snow.

Hank talks about space elevators, and why we shouldn't expect to see one any time soon.

Hank summarizes the five reasons why infrared telescopes were supposed to be impossible to build, and then describes how a team of scientists and engineers overcame those obstacles to build the James Webb Space Telescope.

The future is bright for those of you who want to be asteroid miners! You might soon get your chance!

Some satellites orbit in the same direction the planet rotates, which means they get a boost for their launch, but most have orbits where that isn’t ideal, and that creates some challenges for engineers.

On October 4, 1957, the Soviet Union launched the satellite Sputnik and, with it, an international space race. The United States and the Soviet Union rushed to declare dominance of space for 18 years, until the two countries agreed to a...

In the 1600s, the Dutch East India Company employed hundreds of ships to trade goods around the globe. In order to fund their voyages, the company turned to private citizens to invest money to support trips in exchange for a share of the...

60 years ago, in January 1958, the United States launched its first satellite, Explorer 1.

In this video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal to the...

The welding process usually involves pretty extreme levels of heat. But it turns out that in the cold vacuum of space, metals can weld together... automatically.

We have some good news this week for all the James Webb fans out there, as well as a look a some creative chemistry that may help us find the first solid evidence of an exomoon!

These days, it seems like we're finding water all over the solar system. Still, it takes a lot more than a little H2O to support life.

From launching probes to ferrying experiment racks to the ISS, the Space Shuttle Atlantis has left quite the legacy on space exploration and scientific research.

In the past few years the rise of crowdfunding has allowed for some pretty cool stuff to start existing, and today Hank is excited to announce another awesome Kickstarter - Planetary Resources (of asteroid mining fame) in partnership...

There's a region of Earth's atmosphere known as the South Atlantic Anomaly, and it’s one of the most dangerous near-Earth areas of space, both for satellites and humans.

Researchers think a planet-wide groundwater system may have once existed on Mars, and SpaceX launched the very first commercial crew capsule which docked on the International Space Station!

In the 1960s, the USA almost put a ring around the Earth by launching hundreds of millions of tiny copper needles into space in an attempt to create a reliable boost for their communications systems.

NASA's working on a mission to send a probe and a lander to Europa, but there are many challenges to overcome to make it happen.
