NASA's oldest astronaut says space made him feel 30 again

Arab Times29-04-2025

CAPE CANAVERAL, Fla., April 29, (AP): Fresh from space, NASA's oldest full-time astronaut said Monday that weightlessness made him feel decades younger, with everyday aches and pains vanishing.
Don Pettit marked his 70th birthday on April 20 by plunging through the atmosphere in a Russian Soyuz capsule to wrap up a seven-month mission at the International Space Station.
In his first public remarks since touchdown, Pettit said he threw up all over the Kazak steppes upon touchdown, the result of feeling gravity for the first time in 220 days.
Returning to Earth has always been "a significant challenge' for his body, Pettit said from NASA's Johnson Space Center in Houston.
"I didn't look too good because I didn't feel too good,' he said, adding that his body's normal "creaks and groans" returned.
In weightlessness, on the other hand, Pettit felt the decades melt away.
"It makes me feel like I'm 30 years old again," said Pettit, an astronaut since 1996 who ventured to space four times. "All that kind of stuff heals up because you're sleeping, you're just floating and your body, all these little aches and pains and everything heal up."
Mercury astronaut John Glenn was 77 when he returned to orbit on a short shuttle flight in 1998. But he'd been gone from NASA for decades and was close to wrapping up his Senate career.
Even a pair of 90-year-olds have flown to space, but only on 10-minute up-and-down hops by Jeff Bezos' Blue Origin rocket company.
Pettit, an engineer who still feels "like a little kid inside," focused on his astrophotography while at the space station, capturing auroras, comets and satellites streaking off in the distance.
He also conducted a slew of physics experiments in his spare time, like blowing and stacking bubbles, and forming a perfect ball of honey on a spoon with peanut butter, in order to share the experience with others.
"I've got a few more good years left," Pettit said. "I could see getting another flight or two in before I'm ready to hang up my rocket nozzles.'

Film festival showcases what AI can do on the big screen

NEW YORK, June 9, (AP): Artificial intelligence's use in movie making is exploding. And a young film festival, now in its junior year, is showcasing what this technology can do on screen today. The annual AI Film Festival organized by Runway, a company that specializes in AI-generated video, kicked off in New York Thursday night with ten short films from around the world making their debut on the big screen. "Three years ago, this was such a crazy idea,' Runway CEO Cristóbal Valenzuela told the crowd. "Today, millions of people are making billions of videos using tools we only dreamed of.' The film festival itself has grown significantly since its 2023 debut. About 300 people submitted films when it first began, Valenzuela said, compared to about 6,000 submissions received this year. The one and half-hour lineup stretched across a range of creative styles and ambitious themes - with Jacob Adler's " Total Pixel Space " taking home the festival's top prize. The 9-minute and 28-second film questions how many possible images - real or not - exist in the digital space, and uses math to calculate a colossal number. A stunning series of images, ranging from the familiar life moments to those that completely bend reality, gives viewers a glimpse of what's out there. Meanwhile, Andrew Salter's "Jailbird," which snagged second place, chronicles a chicken's journey - from the bird's perspective - to a human prison in the United Kingdom to take part in a joint-rehabilitation program. And "One,' a futuristic story by Ricardo Villavicencio and Edward Saatchi about interplanetary travel followed in third place. The 10 films shown were finalists selected from thousands submitted to Runway's AI Film Festival this year. The shorts will also be shown at screenings held in Los Angeles and Paris next week. How AI is used and executed is a factor judges evaluate when determining festival winners. But not every film entered was made entirely using AI. While submission criteria requires each movie include the use of AI-generated video, there's no set threshold, meaning some films can take a more "mixed media' approach - such as combining live shots of actors or real-life images and sounds with AI-generated elements. "We're trying to encourage people to explore and experiment with it,' Valenzuela said in an interview prior to Thursday's screening. Creating a coherent film using generative AI is no easy feat. It can take a long list of directions and numerous, detailed prompts to get even a short scene to make sense and look consistent. Still, the scope of what this kind of technology can do has grown significantly since Runway's first AI Film Festival in 2023 - and Valenzuela says that's reflected in today's submissions. While there are still limits, AI-generated video is becoming more and more life-like and realistic. Runway encourages the use of its own AI tools for films entered into its festival, but creators are also allowed to turn to other resources and tools as they put together the films - and across the industry, tools that use AI to create videos spanning from text, image and/or audio prompts have rapidly improved over recent years, while becoming increasingly available. "The way (this technology) has lived within film and media culture, and pop culture, has really accelerated,' said Joshua Glick, an associate professor of film and electronic arts at Bard College. He adds that Runway's film fest, which is among a handful of showcases aimed at spotlighting AI's creative capabilities, arrives as companies in this space are searching for heightened "legitimacy and recognition' for the tools they are creating - with aims to cement partnerships in Hollywood as a result. AI's presence in Hollywood is already far-reaching, and perhaps more expansive than many moviegoers realize. Beyond "headline-grabbing' (and at times controversial) applications that big-budget films have done to "de-age' actors or create eye-catching stunts, Glick notes, this technology is often incorporated in an array of post-production editing, digital touch-ups and additional behind-the-scenes work like sorting footage. Industry executives repeatedly point to how AI can improve efficiency in the movie making process - allowing creatives to perform a task that once took hours, for example, in a matter of minutes - and foster further innovation. Still, AI's rapid growth and adoption has also heightened anxieties around the burgeoning technology - notably its implications for workers. The International Alliance of Theatrical Stage Employees - which represents behind-the-scenes entertainment workers in the U.S. and Canada - has "long embraced new technologies that enhance storytelling,' Vanessa Holtgrewe, IATSE's international vice president, said in an emailed statement. "But we've also been clear: AI must not be used to undermine workers' rights or livelihoods.' IATSE and other unions have continued to meet with major studios and establish provisions in efforts to provide guardrails around the use of AI. The Screen Actors Guild-American Federation of Television and Radio Artists has also been vocal about AI protections for its members, a key sticking point in recent labor actions. For Runway's AI Film Festival, Valenzuela hopes screening films that incorporate AI-generated video can showcase what's possible - and how he says this technology can help, not hurt, creatives in the work they do today. "It's natural to fear change ... (But) it's important to understand what you can do with it," Valenzuela said. Even filmmaking, he adds, was born "because of scientific breakthroughs that at the time were very uncomfortable for many people."

India's new space hero: Shubhanshu Shukla set to make history on ISS

KENNEDY SPACE CENTER, Florida, June 4: Next week, the Axiom Mission 4 (Ax-4) is set to launch from NASA's Kennedy Space Center, marking a historic moment as Indian Air Force Group Captain Shubhanshu Shukla joins the crew to travel to the International Space Station (ISS). Scheduled for liftoff on June 10 at 08:22 EDT (12:22 GMT; 17:52 IST), the mission will see Shukla become only the second Indian ever to go to space and the first to visit the ISS. The flight's significance has captured widespread attention in India, coming 41 years after cosmonaut Rakesh Sharma became the country's first astronaut during his 1984 Soviet Soyuz mission, where he spent nearly eight days in orbit. Ax-4's four-member international crew includes mission commander and former NASA astronaut Peggy Whitson, a veteran with two prior ISS commands, hundreds of days in space, and 10 spacewalks under her belt. Joining them are Slawosz Uznanski-Wisniewski from Poland and Tibor Kapu from Hungary, both returning their nations to space after more than four decades. As pilot, Group Captain Shukla will serve as second-in-command, assisting with critical spacecraft operations during launch, docking, undocking, and re-entry. The crew has been in quarantine since May 25 to prepare for the mission. At a press conference held on Tuesday evening, the astronauts introduced 'Joy' — a small white toy swan they joked would be the 'fifth crew member' on Ax-4. Commander Whitson expressed confidence in the team, saying, 'We are good for the launch, we have completed all the training, and the team has bonded well.' Shukla shared his excitement, calling the past year 'nothing short of transformative.' 'It has been an amazing journey so far, but the best is yet to come,' he said. 'As I go into space, I carry not just instruments and equipment, I carry hopes and dreams of a billion hearts. I request all Indians to pray for the success of our mission.' The 39-year-old was one of four Indian Air Force officers shortlisted last year to participate in India's maiden human spaceflight, the Gaganyaan mission, slated for 2027. Gaganyaan aims to send three astronauts into a 400km orbit for three days. India has also announced plans to build its own space station by 2035 and send an astronaut to the Moon by 2040. The Ax-4 mission is a collaborative venture between NASA, the Indian Space Research Organisation (ISRO), and the European Space Agency (ESA), operated commercially by Houston-based Axiom Space. The launch vehicle will be SpaceX's Falcon 9 rocket, carrying the Crew Dragon capsule. ISRO has invested ₹5 billion (around $59 million) for Shukla's seat and training. ISRO Chairman V. Narayanan highlighted the mission's importance, saying the experience gained will be 'phenomenal' for India's space programme. 'The training, exposure to facilities, and experience conducting experiments in space will be invaluable,' he added. ISRO project director Sudeesh Balan noted that Shukla has undergone rigorous physical and psychological training since August last year to prepare for this journey. Born on October 10, 1985, in Lucknow, Shukla joined the Indian Air Force as a fighter pilot in 2006. With over 2,000 hours of flying experience, he has piloted various aircraft including MiGs, Sukhois, Dorniers, Jaguars, and Hawks. His sister, Shuchi Mishra, revealed that his entry into the Air Force was 'accidental' — a high school friend passed on a National Defence Academy application form that Shukla filled out instead, leading to his selection. She expressed immense pride, saying, 'He's a part of our family and our country's journey. We hope his trip inspires the next generation.' Aside from piloting the mission, Shukla will be involved in a packed schedule aboard the ISS, which includes engaging with Indian students through live events aimed at inspiring youth in space technology. The crew will conduct 60 scientific experiments, seven of which originate from India. ISRO's experiments focus on diverse fields such as biology, microgravity effects, and crop science. One key study will examine how spaceflight affects six varieties of crop seeds, aiming to understand how crops might be grown for future long-term space missions. Seeds will be analyzed over multiple generations to identify traits suited for space agriculture. Another experiment involves cultivating three strains of microalgae with potential applications in food, fuel, and life support systems, helping to identify strains that thrive in microgravity. ISRO will also study tardigrades — microscopic animals known for surviving extreme conditions — to observe their reproduction and revival in space. Additional research will explore muscle loss in microgravity and investigate how prolonged use of computer screens affects astronauts' physical and cognitive health, including eye movement and stress levels. These findings may influence the design of future spacecraft interfaces. As India watches closely, Group Captain Shukla's pioneering journey aboard Ax-4 promises to deepen the nation's space expertise and inspire generations to come.

At-home health tests are expanding - here's how to choose the right one

NEW YORK, June 3, (AP): The doctor is in - the mailbox, that is. You can now do self-administered tests for everything from thyroid function to HIV in the privacy of your own home - and that list continues to grow, as the Food and Drug Administration recently approved the first at-home cervical cancer test. While the tests can make it easier for people to access health care and can be helpful for those who have extreme anxiety about sensitive or invasive medical exams, experts warn that most of the tests cannot replace an actual in-person visit. Here's what doctors say you can test for at home, and when you should make the trek to your physician's office. There are two kinds of at-home tests.' In one type, the patient collects the sample and sends it off to a lab; the new cervical cancer test is like this. The other gives an instant result - think COVID-19 and pregnancy tests. HIV home-testing kits can improve rates of diagnosing sexually transmitted infections in rural communities and help people who are nervous about going to the doctor to seek a sensitive test, said Dr. Joseph Cherabie, an infectious diseases specialist in St. Louis. "You really want to get people to care as quickly as possible, but some people could be very anxious about that results as well," Cherabie said. "And they have very negative reactions.' Labs are required to report a positive HIV test, instead of putting the onus on the patient who took the test, Cherabie said, and, often, the patient is matched up with HIV support services. "If you are part of a sexual and gender minority community, going to a doctor's office can be full of a lot of historical trauma, and you may prefer to just do testing at home without anyone judging you or asking you invasive questions about your sex life,' Cherabie said. The new cervical cancer test - which tests for strains of human papillomavirus, or HPV - involves a testing swab that's like a tampon, said Dr. Susan Modesitt, a gynecologic oncologist at Emory University in Atlanta. It is not, Modesitt said, a replacement for a Pap smear, the exam in which a metal speculum is inserted in the vagina to scrape cervix cells. A doctor's visit also involves a pelvic exam, a chance to talk about abnormal bleeding - a sign of endometrial cancer - and other symptoms and issues, like menopause or STIs. "There are so many other reasons to see your doctor and get an exam outside of a cervical cancer screening,' she said. The at-home cervical cancer test from Teal Health requires a prescription, and the company said that results are not left for the patient to interpret. Some at-home tests can replace a trip to the doctor's office. That's especially true in rural areas, where it can be difficult to get a colonoscopy. "The colonoscopy requires a pre-op, and you have to drive maybe 70 miles for it,' said Dr. Steven Furr, board chair of the American Academy of Family Physicians who practices in rural Alabama. "You get anesthesia. It's actually almost like a surgical procedure in many ways. "So, for a lot of people, that's pretty arduous. That's where an at-home test can come in handy.' But, Furr said, if your test reveals issues, you need to go to your doctor. Plus, patients should always discuss test results with their physician instead of interpreting them on their own, he said. If you have symptoms of what you're testing for, go to the doctor. At-home colon cancer tests aren't the right option for people with a history of colon cancer or high-risk conditions, such as inflammatory bowel disease, said Dr. Zachariah Foda, a gastroenterologist at Johns Hopkins. He added that they're also not recommended for people who are having GI symptoms. While there are tests for many things - running anywhere from $15 to $400, depending on what is being evaluated - Furr said it's essential to make sure that your test is FDA-approved so you can better trust the results. "Anytime we get people involved in their own health care and help them understand what's going on, I think that's a good thing and it gives us a chance to talk,' he said. "Any kind of screening is better than no screening.'
