Supersonic air travel is finally coming back

Supersonic air travel is finally coming back

Supersonic air travel is back. 15 years after the Concorde was grounded, everyone from aerospace companies to NASA to small startups is working to bring back ultrafast civilian aircraft. We take a look at the engineering challenges that make supersonic flight so difficult, and try to figure out what’s different about this new generation of…

We decoded NASA’s messages to aliens by hand

We decoded NASA’s messages to aliens by hand

In 1977, twin golden records were sent into space on the Voyager 1 and 2 spacecraft. Still sailing through space at nearly 60,000 km per hour, the records contain sound, songs, and images from earth. But how did NASA include images on an analog record? Here, we decoded the audio, and see the images the…

How four rogue satellites could change the spaceflight industry

How four rogue satellites could change the spaceflight industry

Earlier this year, a company launched four tiny satellites into orbit without permission. These “rogue satellites” caused an uproar in the space community, and in the future, others like them could increase the risk of catastrophic collisions in orbit. We talked to some space experts about what’s at stake when no one knows exactly what’s…

Building a lunar base out of Moon dust

Building a lunar base out of Moon dust

Welcome to NASA’s Kennedy Space Center. Here, engineers are dreaming up new technologies that will help build settlements on the Moon or Mars via NASA’s experimental “Swamp Works” lab. With everyone from NASA to Elon Musk and Jeff Bezos looking to send people to the Moon and beyond, the Swamp Works engineers are hard at…

Designing a tiny home to orbit the Moon

Designing a tiny home to orbit the Moon

NASA wants to build another space station — except this one won’t live in a close orbit around Earth. Instead, it will be sent into deep space to orbit around the moon and then someday…Mars. Within the last year, NASA has begun planning for a much smaller astronaut outpost, a new destination dubbed the Gateway.…

A microscopic look at why the world is running out of sand

A microscopic look at why the world is running out of sand

Humans are using more sand than the Earth is naturally producing, and that’s a problem for the global construction industry. But it turns out that the usefulness of sand depends on the science of each tiny little grain. We went on a sand scavenger hunt to collect some samples, look at them under a microscope,…

How astronauts handle medical meltdowns in space

How astronauts handle medical meltdowns in space

When astronauts go into space they need to be in peak physical fitness, but that doesn’t mean they can’t get sick. And when they do, there is no clinic or hospital nearby. In this episode, Loren visits the STRATUS Center in Boston, where simulations are being developed to train astronauts on how to handle medical…

This monster plant is trying to take over. What if we let it?

This monster plant is trying to take over. What if we let it?

Silicon Valley is home to tech giants, venture capital…and a years-long battle between an invasive species, a tiny bird, and a bunch of scientists trying to decide what counts as “nature.” We put on the biggest boots we could find and headed out to the strange salt flats of the San Francisco bay to check…

How NYC plans to survive the next superstorm

How NYC plans to survive the next superstorm

Sandy hit New York City almost six years ago and the city is still recovering. As storms grow even more frequent and severe, cities around the world are struggling to prepare themselves for the worst. We took a behind-the-scenes look at New York’s subway system to see all the disaster-grade gear the city is installing…
