NASA, Boeing delay Starliner astronaut landing to June 26
(NASA)
The return to Earth of Boeing's Starliner capsule will be delayed a few more days due to thruster troubleshooting and a scheduled spacewalk. NASA announced June 18 that Starliner will conclude its first human mission to the International Space Station (ISS) no earlier than June 26, nearly three weeks after it launched. Landing that day is scheduled to occur at White Sands Space Harbor in New Mexico at 4:51 a.m. EDT (0851 GMT). We'll carry it live here at Space.com, via NASA Television.

(Richard Baker / In Pictures via Getty Images)
Summer officially begins in the Northern Hemisphere today (June 20), marking the longest day of the year. During the summer solstice, also known as the June solstice, the sun reaches its highest and northernmost point in the sky. It marks the beginning of the summer season in the Northern Hemisphere and winter in the Southern Hemisphere, with the Northern Hemisphere receiving the most daylight hours of the year, and the Southern Hemisphere receiving the least.

We need an astronaut health database
(NASA)
Scientists have created the first-ever aerospace medicine biobank to help outline the impact spaceflight has on astronauts' health. This repository integrates data and samples from various missions, including those performed by SpaceX and NASA, enabling researchers to compare and standardize space medicine findings and apply their results to future missions.

Iconic Crab Nebula shines in gorgeous JWST image
(NASA, ESA, CSA, STScI, Tea Temim - Princeton University)
In July 1054, astronomers in China documented a "guest star" in the sky that shone as brightly as Jupiter for nearly a month before gradually fading into invisibility. That "star" was, in fact, a cloud of debris blown into space by a dying star roughly 6,500 light-years away in the constellation Taurus. In the 19th century, Irish astronomer Lord Rosse named the curious object the Crab Nebula, not least because it appeared to have "streams running out like claws in every direction."

SpaceX to launch European TV satellite after delays
(SES/SpaceX)
A Falcon 9 rocket is now scheduled to launch Luxembourg-based telecom company SES' Astra 1P satellite from Florida's Cape Canaveral Space Force Station on Thursday (June 20) during a nearly three-hour window that opens at 5:35 p.m. EDT (2135 GMT). The liftoff had originally been scheduled for Tuesday, but elevated winds at the launch site forced SpaceX to stand down a day. The company then pushed the attempted liftoff back another 24 hours, again due to weather concerns.

Doctor Who 'Legend of Ruby Sunday': Who is Susan Triad?
(BBC)
"There's always a Twist at the end," proclaimed the song and dance routine at the end of "The Devil's Chord." The penultimate episode of this "Doctor Who" season has delivered on that promise. Susan Twist, an actor who's had numerous cameos in the latest run of episodes, finally took center stage as tech entrepreneur Susan Triad, in a plotline that has big ramifications for the Doctor (Ncuti Gatwa), Ruby Sunday (Millie Gibson), planet Earth and the universe as a whole. "It is not true that I cast Susan for her name," laughs showrunner Russell T. Davies on behind-the-scenes companion show "Doctor Who: Unleashed. "But the name helped."
