Tourists Touch Space, Turtle Troubles & Tribute to a Moon Explorer

From Virgin Galactic's space tourism to William Anders' passing, emerging science news covers a wide scope. Warmer temperatures in Malaysia threaten turtle populations, while a genome study traces the horse domestication timeline, revealing two phases of equine influence on human history.

Following is a summary of current science news briefs.

Virgin Galactic spaceplane takes tourists on flight

Virgin Galactic flew four tourists to the edge of space and back aboard its spaceplane, marking the second flight this year, the Richard Branson-founded company said on Saturday. The Galactic 07 mission carried Turkish, U.S. and Italian passengers to an altitude of about 55 miles (88.51 km) on a flight lasting slightly more than an hour.

Apollo 8 astronaut William Anders, who took 'Earthrise' photo, dead in plane crash

Retired astronaut William Anders, who was one of the first three humans to orbit the moon, capturing the famed "Earthrise" photo during NASA's Apollo 8 mission in 1968, died on Friday in the crash of a small airplane in Washington state. He was 90. NASA chief Bill Nelson paid tribute to Anders on social media with a post of the iconic image of Earth rising over the lunar horizon, saying the former Air Force pilot "offered to humanity among the deepest of gifts an astronaut can give."

In Malaysia, warmer temperatures mean fewer male turtles, hurting conservation efforts

On a secluded Malaysian beach, a group of volunteers carefully retrieved newly laid sea turtle eggs in the sand and moved them to a shady, cooler location, in response to fears by researchers that warmer weather is leading to fewer male hatchlings. The temperature of the developing turtle eggs is what determines sex. Observers at the Chagar Hutang Turtle Sanctuary on Redang Island believe they are already seeing fewer males being hatched due to climate change - with the situation made worse this year by prolonged hot and dry spells caused by the El Niño weather phenomenon.

Genome study shows how horses galloped into human history

The advent of horse-based transportation represented one of the seminal moments for humankind, connecting ancient peoples by enabling them to move quickly over long distances for the first time while also transforming how wars were waged. But the timing of equine domestication and the subsequent broad use of horse power has been a matter of contention. An analysis of genome data from 475 ancient horses and 77 modern ones is providing clarity. It revealed that domestication actually occurred twice - the first time being a dead end - and traced the rise of horse-based mobility to around 2200 BC in Eurasia, centuries later than previously thought.
