94 The Ever-Working Mars Orbiter Passes 50,000 Orbits
Esp 012897 1685 580x230

Most of us never do one thing 50,000 times in our life. So for NASA’s Mars Reconnaissance Orbiter (MRO), completing 50,000 orbits around the red planet is a big deal. And, it only took 10 years to do so.

The MRO could be called one of NASA’s flagship missions. It’s presence in orbit around Mars has helped open up our understanding of that planet immensely. And it’s done so while providing us a steady stream of e...

86 ARCA Unveils the World’s first Single-Stage-to-Orbit Rocket

Since the beginning of the Space Age, scientists have relied on multi-stage rockets in order to put spacecraft and payloads into orbit. The same technology has allowed for missions farther into space, sending robotic spacecraft to every planet in the Solar System, and astronauts to the Moon. But looking to the future, it is clear that new ideas will be needed in order to cut costs and expand launch services.

Hence why the ARCA Space Corporation

81 What’s the Difference Between a Rocket and Space Plane? Amazing Hand-Drawn Animations Explain It All

You gotta love Earth’s atmosphere. It basically makes life (as we know it) possible on our planet by providing warmth and air to breathe, as well as protecting us from nasty space things like radiation and smaller asteroids. But for studying space (i.e., astronomy) or coming back to Earth from space, the atmosphere is a pain.

Last year, we introduced you to freelance animato...

80 How Long is a Year on Pluto?

Discovered in 1930 by Clyde Tombaugh, Pluto was once thought to be the ninth and outermost planet of the Solar System. However, due to the formal definition adopted in 2006 at the 26th General Assembly of the International Astronomical Union (IAU), Pluto ceased being the ninth planet of the Solar System and has become alternately known as a “Dwarf Planet”, “Plutiod”, Trans-Neptunian Object (TNO) and Kuiper Belt Object (KB...

80 Process Behind Martian Streaks Continues To Puzzle

It’s a well-documented fact that roughly 4 billion years ago, Mars had liquid water flowing on its surface. However, there have also been recent findings that suggest that Mars might periodically have liquid water on its surface today. One of the strongest bits of evidence comes in the form of Recurring Slope Lineae, which are ventured to be seasonal flows of salty water which occur during Mars’ warmest months.

However, a

78 Finite Light — Why We Always Look Back In Time

Beads of rainwater on a poplar leaf act like lenses, focusing light and enlarging the leaf’s network of veins. Moving at 186,000 miles per second, light from the leaf arrives at your eye 0.5 nanosecond later. A blink of an eye takes 600,000 times as much time! Credit: Bob King

Before we really get started on today’s episode, I’d like to share a bunch of really cool pictures created by my friend Kevin Gill. Kevin’s a computer programmer, 3-D animator and works on climate science data for NASA.

And in his spare time, he uses his skills to help him imagine what the Universe could look like. For example, he’s mapped out what a

70 Four Candidates For Planet 9 Located

A concentrated three-day search for a mysterious, unseen planet in the far reaches of our own solar system has yielded four possible candidates. The search for the so-called Planet 9 was part of a real-time search with a Zooniverse citizen science project, in coordination with the BBC’s Stargazing Live broadcast from the Australian National University’s Siding Spring Observatory.
