From Cosmic Collisions to Habitable Moons: Your Daily Space Update

0:00 Anna: Welcome to Astronomy Daily, the podcast where we dive into the latest wonders of space and astronomy while drinking coffee. I'm Anna, and joining me is my co host, Avery. Hey Avery, it's January 6, 2026. I trust the new year is still treating you well. Avery: Hey, Anna. And uh, hello to everyone listening. It's been great. Lots of clear skies for stargazing lately. 2026 is already delivering some intriguing storeys, from satellite mishaps to upcoming, um, launches and about life in the universe.

0:33 We've got six solid ones today, so let's not waste any time and get started. Anna: First up, a bit of bad luck for a brand new satellite. Spain's newest communications bird, Spainsat NG2, got hit by a space particle while heading to its final orbit. Avery: Yeah, this one's operated by Histasat for Spain's Ministry of Defence. Built by Airbus as part of a 2 billion euro pair for advanced government comms across Europe. It launched on a Falcon 9 back in October 20and the strike happened at around 31,000 miles up.

1:06 Actually higher than its target geostationary spot at 22,000 miles. Anna: The particle impact was reported just a few days ago on January 2nd. They're calling it a space particle, which could mean anything from a micrometeoroid to a bit of space debris. Damage extent is still unknown, but Histasat quickly activated a contingency plan to keep services running for the Defence Ministry and other clients without interruption. Avery: Their team's analysing data now and if needed, they'll replace it asap.

1:39 It's a reminder of how risky the space environment is. Even in high orbits, collisions can happen. Glad they had backups in place. Anna: Absolutely. Space is harsh, but redundancy saves the day. Avery: Shifting to launches, we've got a busy week ahead with several missions on the docket. SpaceX is leading the pack with multiple. Anna: Falcon 9 flights starting January 8th. Starlink Group 696 with 29 V2 mini satellites from Cape Canaveral. Then on the 10th, Group 6 97, another 29 for the same shell.

2:13 These are boosting the constellation that's already serving millions globally. Avery: And on the 11th, a cool rideshare called Twilight, or Pandora, and others from Vandenkirk into sun synchronous orbit. Highlights include NASA's Pandora mission to observe exoplanet transits invisible in IR for atmospheric clues. Plus Kepler's first operational SATs for a laser linked mesh network. Spire's hyperspect microwave sounder for better weather Data, and some Lemmer 2 birds. Anna: Then ISRO kicks off their 2026 on January 12th with a PSLV carrying EOS N1, an Earth observation sat, possibly hyperspectral for defence, and 18 rideshares including an experimental re entry capsule.

2:59 Avery: It's a packed lineup Starlink expansion, exoplanet science, weather tech and more exciting to see rideshares making space accessible. Anna: Next, some fascinating lab work bolstering one of the leading ideas on how life began on Earth the RNA World hypothesis. Avery: The hypothesis says rna, that versatile molecule that can store info like DNA and catalyse reactions like proteins, might have been the first self replicating life precursor. A team led by Yuta Hidekawa from Toho University mixed RNA building blocks, ribose, sugar free phosphates, nucleobases and borates from seawater and basalt rock.

3:40 Anna: They heated and dried the mix, mimicking underground aquifers on early Earth. Surprisingly, borates didn't block formation, they stabilised ribose and helped phosphates, allowing RNA to form naturally through the discontinuous synthesis model steps. Avery: This is big because all those ingredients have been found in space. Ribose on asteroid Bennu via Osiris REX A massive impact 4.3 billion years could have delivered them Kickstarting RNA in borate Rick spots just before life's earliest signs.

4:13 Anna: Implications Life might have emerged faster than thought and similar chemistry could happen on Mars where borates are detected. It's not proof, but strong lab support for RNA as the bridge to life. Avery: Love how this ties astrobiology to origins right here on Earth. Anna: Speaking of the moon, 2026 is shaping up um for a private lunar landing rush with several companies aiming to t touch down. Avery: We're seeing multiple commercial missions targeting the surface this year, part of the broader push with NASA's CLPS programme and private ventures.

4:49 Though details vary, expect attempts from players like Intuitive Machines, ispace and others. Building on recent efforts, these soft landers. Anna: And rovers are scouting resources, testing tech and paving the way for sustained presence. Successes could accelerate the moon economy. Avery: Definitely 2026 could be a pivotal year for private lunar exploration. Anna: Now an ambitious proposal to hunt for habitable moons around distant giant exoplanets. Avery: A team um including Thomas Winterhallder from ESO suggests building a kilometric baseline interferometer mirrors kilometres apart for ultra high resolution down to 1 microarc second.

5:34 Paired with the upcoming Extremely Large Telescope's 39 metre mirror, it could spot Earth sized exomoons out 652 light years via astrometric wobbles. Anna: Current methods like transits are tricky for moons around far out gas giants where habitable zones might rely on tidal heating like Europa or Enceladus. This setup could directly image planets and detect moon signals. Avery: Challenges are huge, costs in billions tech development post 2028elt but if it works, we might find the first truly habitable exo worlds powered by internal heat, not.

6:12 Anna: Just starlight Mind blowing potential for life beyond Earth like planets Finally, China's Chang'. Avery: E 7 mission is gearing up to probe the moon's South Pole secrets, especially water ice. Anna: The stack includes an orbiter lander rover, a hopping probe for tough terrain and a relay sat target permanently shadowed craters near the pole where ancient ice could reveal the solar system's volatile history. Avery: Ridgelines there get near constant sunlight for power while craters trap ice.

6:45 Objectives Precision landing Resource prospecting in situ analysis key for future bases it's phase. Anna: Four of China's lunar programme, precursor to Chang' E8 for utilisation tech like 3D printing supporting the International Lunar Research Station Hopping probe is clever for accessing shadowed. Avery: Spots rovers can't this could unlock sustainable lunar habitation Water for fuel, air drinking. Anna: And that's it for today's space and astronomy news. What a diverse episode. Satellite hits, launch previews, origins of life, lunar ambitions private and national and exomoon.

7:25 Avery: Hunts the universe keeps surprising us. Thanks for tuning in to Astronomy Daily. We appreciate you joining the conversation. Anna: If you enjoyed this, subscribe and share with a fellow space fan, we'll be back tomorrow with more. Avery: Until then, keep looking up. Anna: Clear skies.
