- US-EU Space Regulatory Clash: The United States has formally opposed the European Union's proposed EU Space Act, arguing that its regulations could impose unfair burdens on American space companies. The act aims to establish a unified regulatory framework for Europe's space industry, focusing on safety, resilience, and sustainability. The US claims that certain provisions unfairly target large telecommunications satellite constellations, particularly SpaceX's Starlink, and calls for recognition of its existing licensing framework to avoid duplication.
- Revisiting a Mars Mistake: A significant scientific error from the 1970s is being re-evaluated as new findings reveal that NASA's Viking Lander mission mistakenly concluded Mars was lifeless. Originally, the absence of detected organic compounds led to this verdict, but it has now been established that organic compounds were indeed present. This has sparked calls for a new mission dedicated to the search for life on Mars, correcting decades of misconceptions.
- Launch Schedule Update: This week’s launch schedule includes high-profile missions such as Blue Origin's new Glenn rocket, which is set to launch the Mars-bound Escapade payload on November 12. However, an ongoing US government shutdown has led to an emergency launch ban during peak hours, affecting several missions and pushing some to later dates.
- Tiangong Space Station's Dual Crew: China's Tiangong Space Station is currently hosting an unprecedented dual crew operation after the return of the Shenzhou 20 astronauts was delayed due to a suspected space debris impact. The Shenzhou 20 crew has been joined by the new Shenzhou 21 crew, creating a temporary six-member occupancy onboard as both crews conduct joint scientific experiments.
- New Insights into the Big Bang: A recent study suggests that the universe's earliest moments were more dynamic than previously understood. Researchers propose that during a brief period, dense clouds of particles dominated over radiation, leading to the formation of primordial black holes. This discovery may provide new insights into the dark history of the universe and its structure.

00:00:00 --> 00:00:02 Avery: Hello and welcome to Astronomy AstroDailyPod,
00:00:02 --> 00:00:05 your essential guide to the latest news from
00:00:05 --> 00:00:07 across the cosmos. I'm Avery.
00:00:07 --> 00:00:10 Anna: And I'm Anna. Coming up on today's episode,
00:00:10 --> 00:00:13 a diplomatic clash over space regulations
00:00:13 --> 00:00:15 between the US and the European Union.
00:00:15 --> 00:00:18 We'll revisit a 50 year old scientific
00:00:18 --> 00:00:20 mistake that changed the course of Mars
00:00:20 --> 00:00:21 exploration.
00:00:21 --> 00:00:24 Avery: Plus, we'll look at an unexpected dual crew
00:00:24 --> 00:00:26 situation aboard, uh, the Tiangong Space
00:00:26 --> 00:00:29 Station, check in on this week's launch
00:00:29 --> 00:00:31 schedule and explore a new theory that sheds
00:00:31 --> 00:00:33 light on what happened less than a second
00:00:33 --> 00:00:34 after the Big Bang.
00:00:35 --> 00:00:37 Anna: Let's begin with our top story.
00:00:37 --> 00:00:39 The United States government has formally
00:00:39 --> 00:00:42 pushed back against the European Union's
00:00:42 --> 00:00:44 proposed EU Space act, calling its
00:00:44 --> 00:00:47 regulations potentially unfair and
00:00:47 --> 00:00:47 unwarranted.
00:00:48 --> 00:00:50 Avery: That's right. The EU Space act, introduced in
00:00:50 --> 00:00:53 June 2025, is designed to create a
00:00:53 --> 00:00:56 unified regulatory framework for Europe's
00:00:56 --> 00:00:59 space industry. It's built on three main
00:00:59 --> 00:01:02 safety, which involves tracking space objects
00:01:02 --> 00:01:05 and mitigating debris Resilience,
00:01:05 --> 00:01:07 focusing on cybersecurity and the continuity
00:01:07 --> 00:01:10 of space based services and sustainability,
00:01:11 --> 00:01:13 which aims to reduce environmental impact and
00:01:13 --> 00:01:15 simplify market access.
00:01:15 --> 00:01:17 Anna: But in a, uh, formal Response released on
00:01:17 --> 00:01:20 November 4, the US State and Commerce
00:01:20 --> 00:01:23 Departments representing over 70American
00:01:23 --> 00:01:26 space companies warned that the act would
00:01:26 --> 00:01:28 impose unacceptable regulatory
00:01:28 --> 00:01:31 burdens. A, uh, primary concern is the
00:01:31 --> 00:01:33 addition of new environmental protection
00:01:33 --> 00:01:35 rules, which the US argues would
00:01:35 --> 00:01:38 significantly drive up costs for operators.
00:01:38 --> 00:01:41 Avery: The response also takes issue with provisions
00:01:41 --> 00:01:44 that seem to favour European operators. In
00:01:44 --> 00:01:46 what appears to be a thinly veiled defence of
00:01:46 --> 00:01:48 SpaceX's Starlink, the document claims the
00:01:48 --> 00:01:51 proposed rules unfairly target large
00:01:51 --> 00:01:54 telecommunications satellite constellations
00:01:54 --> 00:01:56 simply because of their size and success.
00:01:57 --> 00:01:59 Anna: This is particularly evident in the section
00:01:59 --> 00:02:02 addressing satellite brightness. Starlink
00:02:02 --> 00:02:04 has faced criticism for the visual brightness
00:02:04 --> 00:02:07 of its satellites and the US response argues
00:02:07 --> 00:02:10 that a regulation limiting brightness would
00:02:10 --> 00:02:12 be impossible to implement and would
00:02:12 --> 00:02:14 disproportionately harm US companies that
00:02:14 --> 00:02:16 operate at lower altitudes.
00:02:16 --> 00:02:19 Avery: Interestingly, the US document strikes a
00:02:19 --> 00:02:22 somewhat contradictory tone. It first
00:02:22 --> 00:02:24 suggests that space operations are too new
00:02:24 --> 00:02:27 and novel for strict regulation. But
00:02:27 --> 00:02:29 then it highlights that the US already has a
00:02:29 --> 00:02:32 world leading regulatory framework, having
00:02:32 --> 00:02:35 licenced over a thousand launches. The
00:02:35 --> 00:02:37 core request is for the EU to recognise
00:02:37 --> 00:02:40 US licencing to avoid burdensome
00:02:40 --> 00:02:41 duplication.
00:02:41 --> 00:02:43 Anna: With the public consultation period now
00:02:43 --> 00:02:46 closed, the European Commission will review
00:02:46 --> 00:02:48 the feedback, including these pointed
00:02:48 --> 00:02:51 criticisms from the us. The draught, um, may
00:02:51 --> 00:02:53 be revised before it is presented to the
00:02:53 --> 00:02:55 European Parliament and Council for potential
00:02:55 --> 00:02:58 adoption, setting the stage for a critical
00:02:58 --> 00:03:00 phase in transatlantic space policy.
00:03:01 --> 00:03:04 Avery: From modern policy to a decades old
00:03:04 --> 00:03:04 mistake.
00:03:04 --> 00:03:07 Our next story looks at How a scientific
00:03:07 --> 00:03:10 error in the 1970s derailed the search
00:03:10 --> 00:03:13 for life on Mars nearly 50 years
00:03:13 --> 00:03:16 ago, NASA's Viking Lander Mission delivered a
00:03:16 --> 00:03:18 verdict that echoed for generations
00:03:18 --> 00:03:20 Mars was lifeless.
00:03:20 --> 00:03:23 Anna: This conclusion was based on the announcement
00:03:23 --> 00:03:25 from principal investigator Klaus Beeman
00:03:25 --> 00:03:28 that the landers had found no organic
00:03:28 --> 00:03:30 compounds on the Martian surface. While other
00:03:30 --> 00:03:33 life detection experiments on Viking returned
00:03:33 --> 00:03:36 ambiguous results, the absence of organics
00:03:36 --> 00:03:39 was seen as the final word. Without
00:03:39 --> 00:03:41 organic carbon, life as we know it couldn't
00:03:41 --> 00:03:42 exist.
00:03:42 --> 00:03:45 Avery: But here's the critical Beaman's
00:03:45 --> 00:03:47 instrument had in fact detected organic
00:03:47 --> 00:03:50 compounds, specifically methyl chloride and
00:03:50 --> 00:03:53 methylene chloride. However, his team
00:03:53 --> 00:03:55 interpreted them as contaminants brought from
00:03:55 --> 00:03:57 Earth. Even though the mechanism for that
00:03:57 --> 00:03:58 contamination.
00:03:58 --> 00:04:01 Anna: Was unclear, the impact was immediate
00:04:01 --> 00:04:03 and profound. Believing Mars to be
00:04:03 --> 00:04:06 sterile, NASA shifted its focus. It
00:04:06 --> 00:04:09 took another 20 years before the next
00:04:09 --> 00:04:11 successful landing mission, Mars Pathfinder,
00:04:11 --> 00:04:14 touched down. For half a century, the story
00:04:14 --> 00:04:17 of a lifeless Mars has been accepted
00:04:17 --> 00:04:17 wisdom.
00:04:18 --> 00:04:20 Avery: Now that consensus is finally changing.
00:04:20 --> 00:04:22 Thanks to the Curiosity and Perseverance
00:04:22 --> 00:04:25 rovers, we have multiple detections of
00:04:25 --> 00:04:27 various organic compounds, including the same
00:04:27 --> 00:04:30 chlorinated organics found by Viking. It's
00:04:30 --> 00:04:32 now clearer than ever that the original
00:04:32 --> 00:04:33 conclusion was wrong.
00:04:34 --> 00:04:36 Anna: The scientific community is now calling to
00:04:36 --> 00:04:39 correct this longstanding mistake and more
00:04:39 --> 00:04:41 importantly, to shed the negative mindset it
00:04:41 --> 00:04:44 created. The next step, many argue, is to
00:04:44 --> 00:04:46 launch a new robotic mission dedicated
00:04:46 --> 00:04:49 explicitly to the search for life on Mars,
00:04:49 --> 00:04:52 picking up where we should have been decades
00:04:52 --> 00:04:52 ago.
00:04:53 --> 00:04:54 Avery: Next up, let's take a look at this week's
00:04:54 --> 00:04:57 launch roundup. It's a busy schedule
00:04:57 --> 00:04:59 featuring several high profile missions that
00:04:59 --> 00:05:00 were scrubbed last week.
00:05:01 --> 00:05:03 Anna: The second ever launch of Blue Origin's new
00:05:03 --> 00:05:05 Glenn carrying the Mars Bound escapade
00:05:05 --> 00:05:08 payload is now scheduled for no earlier than
00:05:08 --> 00:05:10 Wednesday, November 12th. That's followed a
00:05:10 --> 00:05:13 day later by ULA Atlas v launching the
00:05:13 --> 00:05:16 Viasat 3F2 satellite. Then
00:05:16 --> 00:05:19 on Friday, SpaceX has two Starlink missions
00:05:19 --> 00:05:20 on the manifest.
00:05:20 --> 00:05:22 Avery: The week is expected to close out with a
00:05:22 --> 00:05:24 suborbital electron haste mission from
00:05:24 --> 00:05:27 Wallops and the Sentinel 6B mission.
00:05:27 --> 00:05:29 However, there's a significant factor
00:05:29 --> 00:05:32 affecting the schedule an ongoing U.S.
00:05:32 --> 00:05:33 government shutdown.
00:05:33 --> 00:05:36 Anna: Due to staffing shortages caused by the
00:05:36 --> 00:05:38 shutdown, the FAA issued an emergency
00:05:38 --> 00:05:41 notice banning launches during peak hours
00:05:41 --> 00:05:43 from 6am to 10pm local time
00:05:43 --> 00:05:46 starting Monday, Nov. 10. While a deal
00:05:46 --> 00:05:48 to end the shutdown is reportedly being
00:05:48 --> 00:05:51 worked out, missions like Transporter 15 have
00:05:51 --> 00:05:53 already been pushed to later in the month.
00:05:53 --> 00:05:56 Once the shutdown ends and staffing levels
00:05:56 --> 00:05:59 return to normal, the FAA is expected to lift
00:05:59 --> 00:05:59 the ban.
00:06:00 --> 00:06:02 Avery: Now let's turn our attention to China's
00:06:02 --> 00:06:04 Tiangong Space Station, which is currently
00:06:04 --> 00:06:07 hosting an unprecedented dual crew operation
00:06:07 --> 00:06:10 after a suspected space debris impact delayed
00:06:10 --> 00:06:12 the return of the Shenzhou 20 astronauts.
00:06:13 --> 00:06:15 Anna: That's right, the Shenzhou 20 crew was
00:06:15 --> 00:06:18 scheduled to return, but on November 5, the
00:06:18 --> 00:06:20 China Manned Space Agency, or CMSA,
00:06:21 --> 00:06:23 postponed the landing citing concerns over
00:06:23 --> 00:06:26 possible damage to their return capsule. As a
00:06:26 --> 00:06:28 result, crew Commander Chen Dong and his two
00:06:28 --> 00:06:30 colleagues have remained aboard the station.
00:06:31 --> 00:06:33 Avery: They have now been joined by the newly
00:06:33 --> 00:06:35 arrived three member Shenzhou 21 crew,
00:06:35 --> 00:06:38 creating a temporary six person occupancy on
00:06:38 --> 00:06:41 Tiangong. The CMSA has activated its
00:06:41 --> 00:06:43 emergency plans, emphasising that crew safety
00:06:43 --> 00:06:45 is the absolute top priority.
00:06:46 --> 00:06:48 Anna: Both crews are reportedly conducting joint
00:06:48 --> 00:06:51 scientific experiments, leveraging the robust
00:06:51 --> 00:06:54 systems and ample supplies. Meanwhile,
00:06:54 --> 00:06:56 engineers on the ground are performing
00:06:56 --> 00:06:58 simulations and system tests on the Shenzhou
00:06:58 --> 00:07:00 20 capsule, which remains docked to the
00:07:00 --> 00:07:03 station. No official return date has been
00:07:03 --> 00:07:05 announced, but reports suggest preparations
00:07:05 --> 00:07:08 are underway for a near future return using
00:07:08 --> 00:07:10 the original Shenzhou 20 spacecraft
00:07:11 --> 00:07:12 and finally, let's journey.
00:07:12 --> 00:07:14 Avery: Back to the very beginning of time
00:07:14 --> 00:07:16 Cosmologists have a strong understanding of
00:07:16 --> 00:07:18 the universe's earliest moments, from the
00:07:18 --> 00:07:21 initial explosive inflation to the formation
00:07:21 --> 00:07:24 of the first atomic nuclei. But a period in
00:07:24 --> 00:07:26 between lasting just fractions of a second
00:07:26 --> 00:07:28 has remained the mystery.
00:07:28 --> 00:07:30 Anna: A new study published in Physical Review D
00:07:31 --> 00:07:33 suggests this era was far more dynamic than
00:07:33 --> 00:07:36 previously thought. Researchers explored a
00:07:36 --> 00:07:38 scenario where, for a brief moment, dense
00:07:38 --> 00:07:41 clouds of particles temporarily overpowered
00:07:41 --> 00:07:44 radiation in the newborn cosmos. This shift
00:07:44 --> 00:07:46 would have created a matter dominated era.
00:07:47 --> 00:07:49 Avery: During this time, tiny ripples in density
00:07:49 --> 00:07:51 could have grown into massive halos of
00:07:51 --> 00:07:53 matter. While small by today's standards,
00:07:53 --> 00:07:56 these halos were massive enough to collapse
00:07:56 --> 00:07:58 under their own gravity, leading to a
00:07:58 --> 00:08:00 fascinating the creation of the
00:08:00 --> 00:08:02 universe's very first black holes.
00:08:02 --> 00:08:05 Anna: These primordial black holes would have been
00:08:05 --> 00:08:07 extremely small, far less massive than the
00:08:07 --> 00:08:10 black holes we observe today. Some may have
00:08:10 --> 00:08:12 survived and could even constitute a part of
00:08:12 --> 00:08:14 the dark matter that shapes our universe.
00:08:14 --> 00:08:16 Others would have evaporated long ago through
00:08:16 --> 00:08:18 Hawking radiation.
00:08:18 --> 00:08:21 Avery: The energy released by these evaporating
00:08:21 --> 00:08:23 black holes could have left fingerprints on
00:08:23 --> 00:08:26 the cosmos, potentially altering the
00:08:26 --> 00:08:29 formation of the first elements or the growth
00:08:29 --> 00:08:32 of large scale structures. This work
00:08:32 --> 00:08:35 opens a new window into exploring the
00:08:35 --> 00:08:37 dark, hidden history of our universe's first
00:08:37 --> 00:08:38 second.
00:08:38 --> 00:08:41 Anna: And that brings us to the end of today's
00:08:41 --> 00:08:43 episode. We covered the brewing regulatory
00:08:44 --> 00:08:46 tensions in space policy, corrected a
00:08:46 --> 00:08:49 50 year old misconception about Mars, and
00:08:49 --> 00:08:52 peered into the universe's earliest moments.
00:08:52 --> 00:08:55 Avery: Thank you for joining us from both of us here
00:08:55 --> 00:08:57 at Astronomy AstroDailyPod. Keep looking up
