Astronomers have confirmed they found an atmosphere around an Earth-like rocky exoplanet for the first time. Also, Boeing’s Starliner craft was scheduled to carry humans to the International Space Station in 2017. Its launch is now set for May 17, 2024.

In A First, JWST Detects An Atmosphere Around A Rocky Exoplanet

Earlier this week, astronomers announced they had discovered an atmosphere around a rocky Earth-like planet named 55 Cancri e, about 40 light-years away from Earth, thanks to instruments onboard the JWST telescope. Finding an atmosphere around a rocky planet is a big step for exoplanet exploration: Earth’s atmosphere is crucial to its ability to sustain life, and astronomers need to be able to identify rocky planets that have atmospheres to search for life outside the solar system.

However, 55 Cancri e is likely far too hot to have any life: Researchers estimate the surface temperature to be about 3,100 F, thanks to its close proximity to its sun and a probable magma ocean that envelops the planet. But this could also give clues to Earth’s formation, as its own surface was also once covered by lava.

Jason Dinh, climate editor at Atmos, joins guest host Sophie Bushwick to talk about this and other top news in science this week, including tightening restrictions on risky virus research in the US, possible evidence for a sperm whale “alphabet,” and how environmental changes are leading to an increase in disease in humans, animals, and plants.

Boeing Plans To Fly Humans To The ISS Next Week

When NASA retired its space shuttle program in 2011, the agency had to find a new way to transport astronauts and supplies to the International Space Station (ISS). Russia’s Soyuz program has met that need in the meantime, but NASA has wanted a more local solution. So they started awarding contracts to private US companies who could act as space taxis, including SpaceX, with its Dragon capsule, and Boeing with its Starliner capsule, through the United Launch Alliance (ULA).

Unlike SpaceX, Boeing has yet to fly humans in its spacecraft. But it plans to do so no earlier than next Friday, carrying Butch Wilmore and Suni Williams, NASA astronauts and former Navy pilots to the ISS. Starliner was originally supposed to launch this week, but due to issues with a pressure regulation valve on the Atlas V rocket’s upper stage, ULA had to delay the launch to replace the valve.

Brendan Byrne, assistant news director at Central Florida Public Media, talks with guest host Sophie Bushwick about Boeing’s rocky road to the ISS and how NASA hopes to split the workload of ferrying astronauts between Boeing and SpaceX.

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
