S03E75: Voyager 1's Revival & ISS Spacewalk Setback

Embark on a celestial journey with today's episode of Astronomy Daily - The Podcast, where your host, Anna, brings you the latest cosmic updates. We'll delve into Voyager One's latest achievements as it resumes its science operations after a technical glitch. We'll also discuss the recent spacewalk cancellation on the International Space Station due to a spacesuit discomfort issue. And don't miss out on the new findings from NASA's Perseverance rover on Mars, which has just reached a new area of scientific interest. Stay tuned for these stories and much more.NASA's Voyager One has fully resumed its science operations after resolving a technical issue that had been affecting its capabilities since November 2023. This remarkable spacecraft, now over 15 billion miles from Earth, is once again collecting crucial data from its four science instruments, providing invaluable insights into the nature of interstellar space. After a series of careful diagnostics and repairs, the mission team successfully restored the instruments to their full operational modes. Engineers will continue to perform minor maintenance tasks, including resynchronizing the timekeeping software and maintaining the digital tape recorder that stores data for the plasma wave instrument. As Voyager One continues its journey, it remains one of NASA's most historic missions, shedding light on the mysteries of space far beyond our solar system.A spacesuit discomfort issue forced NASA to cancel a planned spacewalk on the International Space Station today. The spacewalk, set to be a routine six-hour mission involving astronauts Tracy C. Dyson and Matt Dominick, was aimed at conducting necessary repairs and science experiments. However, as the astronauts were preparing for their trek outside the station, NASA astronaut Mike Barrett requested a private line to talk to flight controllers about an unspecified medical issue, leading to the mission's cancellation. Despite the setback, NASA assured the public that there was no emergency, and the mission will be rescheduled.After an arduous journey, NASA's Perseverance rover has reached a new area of scientific interest on Mars, dubbed Bright Angel. The rover navigated through a challenging dune field to avoid boulder-filled terrain, leading it to an ancient river channel full of potential geological treasures. Bright Angel, located at the base of Jezero Crater's northern channel wall, is now being studied for evidence of carbonate and olivine deposits, which could reveal secrets about the ancient river that once flowed into the crater. One particularly intriguing find is Atoko Point, a unique boulder whose composition and origin are currently under investigation.New research suggests that some planets orbiting white dwarfs may retain their water and potentially support life. White dwarfs, with their small size and dim light, provide an excellent backdrop for studying these planets. The study offers a roadmap for finding these elusive worlds and could guide future telescope missions as they search the cosmos for signs of life. The potential for discovering habitable exoplanets around white dwarfs opens up exciting possibilities for understanding planetary systems and life beyond our own solar system.Blue Origin, SpaceX, and United Launch Alliance have secured a monumental $5.6 billion in contracts from the Pentagon for the National Security Space Launch phase three program. This is a significant milestone, especially for Blue Origin, as it's their first time entering the national security launch arena. These contracts, which span over the next five years, will see the companies compete for various crucial launch missions, enhancing competition, driving down costs, and ensuring reliable access to space.In a stunning revelation, the James Webb Space Telescope has discovered that a star long believed to be a single entity, known as WL 20s, is actually a pair of twin stars. Using its mid-infrared instrument, Webb has also detected jets of gas streaming from the north and south poles of these twin stars, adding a new layer of understanding to the processes of stellar formation and evolution. Further observations have shown that each star is encircled by disks of dust and gas, suggesting that planets may be forming within these disks.
