We have the receipts, and we hope that you will hear us out before you hit that @ button. I and aerospace correspondent Erik Madaus are taking on this topic knowing it will bring us a certain amount of internet hate because we recognize that accidents in spaceflight happen when engineers and...
When Asteroids (Don’t) Attack
Artist's concept of the Hera mission gliding past Didymos to Dimorphos. Image credit: ESA For a hot second back in 2004, it looked like there was a couple percent chance the asteroid 99942 Apophis just might crash into the planet Earth on April 13, 2029. And even if...
VIPER May Live to Rove Another Day
A computer generated concept image of the VIPER rover Despite what the contents of this and recent episodes might imply, my passion is for science not for spacecraft. The thing is, sometimes spacecraft are needed to do the science. And lately, I and many others have...
The Cost of Space Flight on the Planet
As a nerdy member of GenX, I can state with pride and shame that I watched Buck Rogers in the early 80s and was constantly fascinated by all the weird ways their writers found for fictional 24th century scientists to misunderstand the relics from the 20th century....
Dino Prints Match Continents
One of the reasons we study the Moon is to help us understand the history of our own planet Earth. The shifting continents and weather patterns of Earth join forces to erase our world’s history. Occasionally, however, our planet reveals its past through the rocks...
Chang’e 5 Returns Some Really Cool Science

Closer Look: Mars is the Future
Since Mars Spirit and Opportunity first set down on Mars in 2004, there has been a continuous robotic presence on the Red Planet. The Phoenix and Insight Landers have answered specific questions about Mars composition and interior, while a small herd of rovers have...
Stonehenge Stones More Geographically Diverse Than Originally Thought
Image credit: Stefan Kühn Before we go, I have a new mystery for you. Researchers, with permission, took a small sample from the altar stone at Stonehenge and examined its composition and structure in a new level of detail. This information made it possible to...
A Star’s Death in Three Acts
While monitoring the sky with optical systems, we’ve found some really weird stuff. Back in 2018, the All Sky Automated Survey for Super Novae discovered a brightening galaxy. Follow -up observations in the X-Ray found the kinds of high energy light that signals a...
Plasma Bubbles Surround Sources of Fast Radio Bursts
In 2007, a student discovered a really weird thing in archival radio data. David Narkevic was working for Duncan Lorimer and found a 5-millisecond burst of energy in the Radio that appeared to be of extragalactic origin. In the years since then, over 100 of these...
Dino-Killer Asteroid Came From the Outer Solar System
A shaded relief image of Mexico's Yucatan Peninsula. NASA/JPL-Caltech. The single messiest day in geologically recorded history was the day the dinosaurs died. On that day, and across the days that would follow, tidal waves wrapped multiple times around our world as...
