‘Just the beginning’: Artemis II crew splashes down after record-breaking moon flyby

Posted on by

The four astronauts touched down on Earth off the coast of California, concluding historic 10-day mission

The Artemis II, and the four astronauts aboard the Orion space capsule, splashed down into the Pacific Ocean off the coast of San Diego on Friday night, with all four astronauts in good health.

“53 years ago, humanity left the moon. This time we return to stay. Let us finish what they started. Let us focus on what was left undone. Let us not go to plant flags and leave, but to stay with firmness in our purpose, with gratitude for the hands who built the machines and with love for the ones that we carry with us,” Nasa’s associate administrator Amit Kshatriya said at the late-night press conference after the astronauts landed.

Astronauts prepare for re-entry several miles off coast of southern California after 10-day lunar fly-by mission

The crew of Artemis II is set to return to earth on Friday following its historic 10-day lunar flyby mission, and Nasa leaders have described the precise logistics needed to get them home.

The return will see the Orion capsule traveling at nearly 24,000mph before making a final splashdown several miles off the coast of San Diego. The operation requires multiple teams and careful coordination to safely extract the crew from the spacecraft.

New study describes what may be the first case of a unified community of chimps, in Uganda, turning on itself

On a June day in 2015, primatologist Aaron Sandel was quietly observing a small cluster of the Ngogo chimpanzee group in Uganda’s Kibale national park when he noticed something strange. As other members of the chimpanzees’ wider group moved closer through the forest, the chimpanzees in front of him began to display nervous behaviour. They grimaced and touched each other for reassurance, acting more like they were about to meet strangers than close companions.

In hindsight, Sandel said, that moment was the first sign of what would become a years-long bloody conflict between a once close-knit group of chimps.

Exclusive: Former UN climate chief to co-chair Lancet Commission examining how sea-level rise is reshaping health, wellbeing and inequality

Countries are being “held hostage” by their reliance on fossil fuels, a former UN climate chief has warned, describing the health impacts of climate change as “the mother of all injustices”.

Christiana Figueres, an international climate negotiator who helped deliver the Paris agreement signed in 2016, made the comments as she was announced on Wednesday as co-chair of a Lancet Commission examining how sea-level rise is reshaping health, wellbeing and inequality.

Nasa astronauts begin journey home having collected eagerly awaited images of impact craters and ridges

Nasa’s Artemis II astronauts have described the powerful emotion felt when soaring over the moon as they photographed impact craters, cracks and ridges and began their long journey home.

Among the eagerly awaited images captured by the crew, who worked in pairs at the Orion capsule windows, are those of the Earth rising from behind the moon, a solar eclipse and parts of the 590-mile (950km) wide Orientale impact basin that have never been observed with the naked eye.

Astronauts had a call with the US president from space after setting record for the farthest-traveled humans from Earth

The crew of Artemis II phoned home from above the moon on Monday night after their record-breaking day, to find Donald Trump musing about how he had saved the US space agency, Nasa, from closing down and telling the astronauts how much they deserved the honor of the president seeking their autographs.

The intermittently uncomfortable 12-minute Earth-to-space call, facilitated by the Nasa administrator and Trump acolyte, Jared Isaacman, featured a lengthy period of silence, several references by the president about his friendship with the retired Canadian ice hockey player Wayne Gretzky, and how “America is the hottest country in the world right now”.

Four astronauts become Earth’s farthest travelled and exceed a 1970 record on the fifth day of the mission

Artemis II astronauts broke Apollo 13’s distance record at 1.57pm eastern time on Monday, hugging each other in the cramped capsule as they made history for being the first four humans to travel the farthest from Earth than anyone before them.

About five hours later, at 7.02pm ET, the crew reached the furthest point in its mission, before swinging back around, at 252,756 miles from Earth – 4,111 miles farther than the ill-fated Apollo 13 mission in 1970.

Jared Isaacman says odds of evidence we are not alone are ‘pretty high’ four days after Artemis II rocket lifted off

The top official at Nasa says that the chance of alien existence is a factor in how the US space agency plans its missions.

Speaking on Sunday, Nasa administrator Jared Isaacman told CNN’s Meet the Press that investigating the existence of alien life “goes to the heart of many things that we do at Nasa”, adding: “Our job here is to go out and try and unlock the secrets of the universe.”

Human brains are designed to detect faces as quickly as possible, which can lead to the perception of ‘false faces’

Faces: we see them in clouds, electrical outlets and even a $28,000 toasted sandwich said to look like the Virgin Mary.

Known as face pareidolia, seeing faces in inanimate objects or patterns of light and shadow is a common phenomenon.

Divers in race against time to unearth wreck of the Dannebroge before seabed becomes construction site

More than 200 years after being sunk by Adm Horatio Nelson and the British fleet, a Danish warship has been discovered on the seabed of Copenhagen harbour by marine archaeologists.

Working in thick sediment and almost zero visibility 15 metres (49ft) beneath the waves, divers are in a race against time to unearth the 19th-century wreck of the Dannebroge before it becomes a construction site in a new housing district being built off the Danish coast.

Discovery at Monte Verde puts north-to-south expansion theory back at centre of heated debate on continent’s human history

A groundbreaking new study may have once again upended our understanding of human prehistory in the Americas.

For years, the predominant theory of how humans arrived in the western hemisphere centred around the Clovis culture, which crossed the Beringia land bridge from Asia between 13,400 and 12,800 years ago, and spread south.

Research finds cockapoo, cavapoo and labradoodle dogs display more undesirable behaviours than breeds they derive from

The UK has oodles of doodles but a study might offer paws for thought: researchers have found some of these designer crossbreed dogs show more behavioural problems than the pure breeds from which they derive.

Crosses between poodles and other dog breeds have become increasingly popular in the UK, with research suggesting the trend is – at least in part – driven by the expectation such dogs will be hypoallergenic, healthy and good with children.
