On Episode 120 of This Week In Space, Rod Pyle and Tariq Malik dive into the 55th anniversary of the Apollo 11 moon landing, discussing the mission's highlights, challenges, and historical significance. They also cover recent space news, including Elon Musk's plans to move SpaceX's headquarters to Texas, the Falcon 9 upper stage failure, and the cancellation of NASA's VIPER rover mission. Looking ahead, the hosts speculate on the future of the Artemis program and the political landscape's influence on space exploration.
From a close encounter between Saturn and the moon to the Southern Delta-Aquariids and a good view of the Northern Crown, there is much to see this week (July 22 to July 28) using just your naked eye.
NASA says its next spacewalk will be delayed indefinitely until engineers understand more about what caused a coolant leak on June 24. Tracy Dyson, a NASA astronaut, had a brief spacesuit leak a month ago while still in the hatch of the International Space Station (ISS). She and Mike Barrett had just opened the door for a 6.5-hour spacewalk for maintenance activities, when showers of ice particles erupted from a spacesuit connection to the ISS. The spacewalk was suspended, but the astronauts were never in any danger, NASA has emphasized.
NASA's Cassini-Huygens spacecraft may have dramatically ended its 20-year mission to explore Saturn's neighborhood seven years ago, when it plunged to into the gas giant, but it is still delivering the scientific goods.
SpaceX's privately-funded crewed mission, Polaris Dawn, is moving toward a launch sometime this summer. The four-person crew, which includes the mission's funder, billionaire philanthropist Jared Isaacman, recently completed acceptance testing for SpaceX's new extravehicular activity (EVA) spacesuits, which they will wear as they become the first private citizens to perform a spacewalk on orbit.

Scientists have long theorized that both Enceladus, one of Saturn's 146 known moons, and Europa, one of Jupiter's four large Galilean moons among its total 95 moons, could host vast liquid water oceans that harbor life. If this is the case, then complex organic molecules like amino acids and nucleic acids, the building blocks of life as we know it, could serve as "biosignatures" of life on the worlds.
