CAPE CANAVERAL, FLA. —
Tom Cruise got a sneak preview of what it’s like to circle Earth in a SpaceX capsule.
Representatives for SpaceX’s first privately chartered flight revealed Friday that the actor took part in a call with the four space tourists orbiting more than 360 miles up. Thursday’s conversation, like the entire three-day flight, was private and so no details were released.
“Maverick, you can be our wingman anytime,” came the announcement from the flight’s Twitter feed. Cruise starred as Navy pilot Pete “Maverick” Mitchell in the 1986 film “Top Gun.” A sequel comes out next year.
Last year, NASA confirmed it was in talks with Cruise about visiting the International Space Station for filming. SpaceX would provide the lift, as it does for NASA astronauts, and like it did Wednesday night for the billionaire up there now with his two contest winners and a hospital worker.
Their flight is due to end Saturday night with a splashdown in the Atlantic off the Florida coast.
The four showed off their capsule in a live broadcast Friday. They’re flying exceedingly high in the automated capsule, even by NASA standards.
SpaceX got them into a 363-mile (585-kilometer) orbit following Wednesday night’s launch from NASA’s Kennedy Space Center. That’s 100 miles (160 kilometers) higher than the International Space Station. It’s so high that they’re completing 15 orbits of Earth daily, compared with 16 for station astronauts.
Until this all-amateur crew, relatively few NASA astronauts had soared that high. The most recent were the shuttle astronauts who worked on the Hubble Space Telescope over multiple flights in the 1990s and 2000s.
To enhance the views, SpaceX outfitted the Dragon capsule with a custom, bubble-shaped dome. Photos of them looking out this large window were posted online, otherwise little else had been publicly released of their first day in space.
Besides talking space with Cruise, the four capsule passengers chatted Thursday with young cancer patients. Hayley Arceneaux, a childhood cancer survivor, led the conversation from orbit with patients from the hospital that saved her life almost 20 years ago: St. Jude Children’s Research Hospital. A 6-year-old-boy wanted to know if there are cows on the moon – like in the nursery rhyme.
“I hope there will be one day. Right now, no, there aren’t,” replied another passenger, Sian Proctor. “We’re going to go back to the moon soon and we’re going to investigate all kinds of things about it.”
The video linkup was not broadcast live, but shared by St. Jude on Friday. Seeing the Earth from so high is “so beautiful,” Arceneaux told them.
Now a physician assistant at St. Jude, Arceneaux is the youngest American in space at age 29.
Pennsylvania entrepreneur Jared Isaacman, 38, purchased the entire flight for an undisclosed amount. He’s seeking to raise $200 million for St. Jude through the flight he’s named Inspiration4, half of that coming from his own pocket.
The two other Dragon riders won their seats through a pair of contests sponsored by Isaacman: Chris Sembroski, 42, a data engineer, and Proctor, 51, a community college educator.
During the broadcast Friday afternoon, Sembroski played a ukulele that will be auctioned off for St. Jude. “You can turn your volume down if you wish, but I’ll give it a shot,” he said.
Proctor, who is an artist, showed off a drawing in her sketchbook of a Dragon capsule being carried by a mythological dragon away from Earth.
All four share SpaceX founder Elon Musk’s quest to open space to everyone.
“Missions like Inspiration4 help advance spaceflight to enable ultimately anyone to go to orbit & beyond,” Musk tweeted Thursday after chatting with his orbiting pioneers.

Guilt, grief and anxiety as young people fear for climate’s future
Overwhelmed, sad, guilty are some of the emotions young people say they feel when they think of Climate Change and their concerns world leaders will fail to tackle it.
Broadly referred to as climate anxiety, research has stacked up to measure its prevalence ahead of the U.N. talks in Glasgow, which begin at the end of the month to thrash out how to put the 2015 Paris Agreement on curbing climate change into effect.
One of the biggest studies to date, funded by Avaaz, an online campaign network, and led by Britain’s University of Bath, surveyed 10,000 young people aged 16-25 years in 10 countries. It published its results in September.
It found around three quarters of those surveyed considered the future frightening, while a lack of action by governments and industry left 45% experiencing climate anxiety and distress that affected their daily lives and functioning.
Elouise Mayall, an ecology student at Britain’s University of East Anglia and member of the UK Youth Climate Coalition, told Reuters she had felt guilty and overwhelmed.
“What I’d be left with is maybe the sense of shame, like, ‘how dare you still want lovely things when the world is ending and you don’t even know if you’re going to have a safe world to grow old in’.”
She spoke of conflicting emotions.
“You might have sadness, there might be fear, there might be a kind of overwhelm,” she said. “And maybe even sometimes a quite like wild optimism.”
Caroline Hickman, a psychotherapist and lecturer at the University of Bath and one of the co-authors of the research published in September, is working to help young people manage climate-related emotions.
“They’re growing up with the grief and the fear and the anxiety about the future,” she told Reuters.
“SENSE OF MEANING”
London-based psychiatrist Alastair Santhouse sees climate change, as well as COVID-19, as potentially adding to the burden, especially for those pre-disposed to anxiety .
For now, climate anxiety alone does not normally require psychiatric help. Painful as it is, it can be positive, provided it does not get out of control.
“Some anxiety about climate change is motivating. It’s just a question of how much anxiety is motivating and how much is unacceptable,” said Santhouse, author of a book that tackles how health services struggle to cope with complex mental issues.
“The worry is that as climate change sets in, there will be a more clear cut mental health impact,” he added.
Among some of the world’s communities that are already the most vulnerable, extreme weather events can also cause problems such as post traumatic stress disorder.
Leading climate campaigner Greta Thunberg, 18, has experienced severe climate anxiety.
“It’s a quite natural response, because, as you see, as the world is today, that no one seems to care about what’s happening, I think it’s only human to feel that way,” she said.
For now, however, she is hopeful because she is doing everything she possibly can.
“When you take action, you also get a sense of meaning that something is happening. If you want to get rid of that anxiety, you can take action against it,” she said.

Rocket failure mars U.S. hypersonic weapon test as others succeed
The Pentagon ‘s hypersonic weapon programs suffered a setback on Thursday when a booster rocket carrying a hypersonic weapon failed, people briefed on the test result said.
The test was intended to validate aspects of one of the Pentagon’s hypersonic glide vehicles in development, two of the people said.
Hypersonic glide vehicles are launched from a rocket in the upper atmosphere before gliding to a target at speeds of more than five times the speed of sound, or about 3,853 miles (6,200 kilometers) per hour.
In a separate series of tests conducted on Wednesday, the U.S. Navy and Army tested hypersonic weapon component prototypes. That test successfully “demonstrated advanced hypersonic technologies, capabilities, and prototype systems in a realistic operating environment,” the Pentagon said in a statement.
The United States and its global rivals have quickened their pace to build hypersonic weapons – the next generation of arms that rob adversaries of reaction time and traditional defeat mechanisms.
U.S. President Joe Biden expressed concern on Wednesday about Chinese hypersonic missiles, days after a media report that Beijing had tested a nuclear-capable hypersonic glide weapon.
Glide bodies are different from their air-breathing hypersonic weapon cousins which use scramjet engine technology and the vehicle’s high speed to forcibly compress incoming air before combustion to enable sustained flight at hypersonic speeds. An air-breathing hypersonic weapon was successfully tested in September.
Companies such as Lockheed Martin and Raytheon Technologies are working to develop the hypersonic weapon capability for the United States.

Patagonian fossils show Jurassic dinosaur had the herd mentality | Saltwire – SaltWire Network
By Will Dunham
(Reuters) – A vast trove of fossils unearthed in Argentina’s southern Patagonia region is offering the oldest-known evidence that some dinosaurs thrived in a complex and well-organized herd structure, with adults caring for the young and sharing a communal nesting ground.
Scientists said on Thursday the fossils include more than 100 dinosaur eggs and the bones of about 80 juveniles and adults of a Jurassic Period plant-eating species called Mussaurus patagonicus, including 20 remarkably complete skeletons. The animals experienced a mass-death event, probably caused by a drought, and their bodies were subsequently buried by wind-blown dust, the researchers said.
“It is a pretty dramatic scene from 193 million years ago that was frozen in time,” said paleontologist Diego Pol of the Egidio Feruglio Paleontological Museum in Trelew, Argentina, who led the research published in the journal Scientific Reports.
Mussaurus, which grew to about 20 feet (6 meters) long and about 1.5 tons, possessed a long neck and tail, with a small head. It was bipedal as an adult but newborns were quadrupedal. Mussaurus lived early in the Jurassic, the second of three periods comprising the age of dinosaurs. It was a relatively large beast for its time – much bigger than contemporaneous meat-eating dinosaurs. Dinosaurs became true giants later in the Jurassic.
“The site is one of a kind,” Pol said. “It preserves a dinosaur nesting ground including delicate and tiny dinosaur skeletons as well as eggs with embryos inside. The specimens we have found showed that herd behavior was present in long-necked dinosaurs since their early history. These were social animals, and we think this may be an important factor to explain their success.”
The animals were found to have been grouped by age at the time of their deaths, with hatchlings and eggs in one area while skeletons of juveniles were clustered nearby. The eggs were arranged in layers within trenches. Adults were found alone or in pairs.
This phenomenon, called “age segregation,” signals a complex social structure, the researchers said, including adults that foraged for meals and cared for the young. The researchers suspect that members of the herd returned to the same spot during successive seasons to form breeding colonies.
“The young were staying with the adults at least until they reached adulthood. It could be that they stayed in the same herd after reaching adulthood, but we don’t have information to corroborate that hypothesis,” said paleontologist and study co-author Vincent Fernandez of the Natural History Museum in London.
Herd behavior also can protect young and vulnerable individuals from attack by predators.
“It’s a strategy for the survival of a species,” Fernandez said.
The oldest previous evidence for dinosaur herd behavior was from about 150 million years ago.
The nesting ground was situated on the dry margins of a lake featuring ferns and conifers in a warm but seasonal climate. The eggs are about the size of a chicken’s, and the skeleton of a hatchling fits in the palm of a human hand. The adults got as heavy as a hippo.
A scanning method called high-resolution X-ray computed tomography confirmed that the embryos inside the eggs indeed were of Mussaurus.
Mussaurus was a type of dinosaur called a sauropodomorph, which represented the first great success story among herbivorous dinosaurs. Sauropodomorphs were an evolutionary forerunner to a group called sauropods known for long necks and tails and four pillar-like legs.
The largest land animals in Earth’s history were the sauropod successors of sauropodomorphs, as exemplified by a later denizen of Patagonia called Argentinosaurus that reached perhaps 118 feet (36 meters) in length and upwards of 70 tons.
