S03E163: SpaceX's Mars Ambitions, Galactic Magnetic Halo, and ESA's DRACO Mission

0:00 Speaker 1: Welcome to Astronomy Daily, your source for the latest space

0:03 Speaker 1: and astronomy news. I'm your host, Anna, and today we'll

0:06 Speaker 1: be covering a range of exciting topics, from SpaceX's ambitious

0:10 Speaker 1: Mars plans to new discoveries about our galaxy's magnetic halo.

0:13 Speaker 1: Strap in for a cosmic journey as we explore the

0:16 Speaker 1: frontiers of space exploration and scientific discovery. Elon Musk has

0:20 Speaker 1: once again set his sights on the Red planet, announcing

0:23 Speaker 1: ambitious plans for SpaceX to launch approximately five uncrued starship

0:28 Speaker 1: missions to Mars within the next two years. This bold

0:32 Speaker 1: timeline aligns with the upcoming Earth Mars transfer window, presenting

0:36 Speaker 1: an ideal opportunity for these pioneering flights. The success of

0:40 Speaker 1: these initial uncrude missions will play a crucial role in

0:43 Speaker 1: determining the timeline for future crude expeditions to Mars. Musk

0:47 Speaker 1: has indicated that if these unmanned flights managed to land

0:51 Speaker 1: safely on the Martian surface, we could see the first

0:53 Speaker 1: crude missions launching in as little as four years. However,

0:57 Speaker 1: should any significant challenges arise during these test flights, the

1:01 Speaker 1: timeline for human missions may be pushed back by an

1:03 Speaker 1: additional two years. It's worth noting that Musk's timelines have

1:07 Speaker 1: been known to shift, and earlier this year he had

1:10 Speaker 1: suggested a five year window for the first uncrewed Mars landing. Nevertheless,

1:14 Speaker 1: these latest announcements underscore SpaceX's unwavering commitment to pushing the

1:20 Speaker 1: boundaries of space exploration and their ultimate goal of establishing

1:24 Speaker 1: a human presence on Mars. In other SpaceX news today,

1:28 Speaker 1: it appears a few feathers are getting ruffled on both

1:31 Speaker 1: sides of this story. The Federal Aviation Administration has recently

1:35 Speaker 1: proposed a hefty six hundred and thirty three thousand dollars

1:38 Speaker 1: fine against SpaceX for violating agency rules. This move has

1:42 Speaker 1: sparked a debate about safety practices in the private space industry.

1:45 Speaker 1: FAA Administrator Mike Whittaker has been vocal about the need

1:49 Speaker 1: for SpaceX to operate at the highest level of safety.

1:51 Speaker 1: He emphasized that the company, now in its twentieth year

1:55 Speaker 1: of operation, needs to adopt more rigorous safety management systems.

2:00 Speaker 1: Pointed out specific incidents that led to the proposed fine,

2:03 Speaker 1: including launches in June and July of last year from

2:06 Speaker 1: Cape Canaveral, Florida, which he claims were conducted without proper permits.

2:11 Speaker 1: He stated, it's the only tool we have to get

2:14 Speaker 1: compliance on safety matters. SpaceX, however, strongly disputes these claims,

2:18 Speaker 1: asserting that every statement made by Whittaker was incorrect. The

2:22 Speaker 1: company maintains that it is the safest and most reliable

2:25 Speaker 1: launch provider in the world and is fully committed to

2:28 Speaker 1: safety in all its operations. This disagreement highlights the ongoing

2:33 Speaker 1: challenges in regulating the rapidly evolving private space industry, where

2:38 Speaker 1: innovation and safety must be carefully balanced. Now onto some

2:42 Speaker 1: astronomy news. In a groundbreaking discovery, scientists have unveiled a

2:46 Speaker 1: magnetic halo surrounding our Milky Way galaxy. This finding is

2:50 Speaker 1: shaking up our understanding of galactic structure and evolution. The study,

2:54 Speaker 1: led by the National Institute for Astrophysics, has revealed magnetized

2:58 Speaker 1: structures stretching and incres sixteen thousand light years beyond the

3:02 Speaker 1: galactic plane. These structures are connected to what are known

3:05 Speaker 1: as the Erecta bubbles, vast regions powered by intense gas

3:09 Speaker 1: and energy outflows primarily caused by supernova explosions. The magnetic

3:14 Speaker 1: fields within these bubbles are organized into thin, filamentary structures,

3:19 Speaker 1: stretching up to one hundred and fifty times the diameter

3:22 Speaker 1: of the full moon. What's particularly exciting is that these

3:24 Speaker 1: magnetic ridges aren't just random formations. They're closely linked to

3:28 Speaker 1: star forming regions in our galaxy, specifically the star forming

3:32 Speaker 1: ring at the end of the galactic bar. This connection

3:35 Speaker 1: provides new insights into how even relatively quiet galaxies like

3:38 Speaker 1: our Milky Way can generate powerful outflows, potentially shedding light

3:43 Speaker 1: on galactic growth processes. This discovery marks a significant leap

3:47 Speaker 1: forward in our understanding of the Milky Way's complex dynamics

3:51 Speaker 1: and the intricate relationship between star formation and large scale

3:55 Speaker 1: galactic structures. SpaceX's Crew nine mission to the International Space

4:00 Speaker 1: Station has hit a snag due to mother Nature. The launch,

4:03 Speaker 1: originally planned for Thursday afternoon, has been pushed back by

4:06 Speaker 1: at least two days because of Tropical Storm Helene. This

4:09 Speaker 1: powerful storm is expected to intensify into a Category three

4:13 Speaker 1: hurricane as it approaches Florida's Gulf Coast. NASA and SpaceX

4:17 Speaker 1: are now eyeing Saturday as the earliest possible launch date,

4:21 Speaker 1: with a tentative liftoff time of one seventeen pm Eastern.

4:24 Speaker 1: The decision to delay comes as a precautionary measure, as

4:28 Speaker 1: the storm's large system is expected to bring high winds

4:31 Speaker 1: and heavy rain to the Cape Canaveral and Merritt Island

4:34 Speaker 1: regions on Florida's east coast. Despite the delay, preparations continue.

4:38 Speaker 1: The Falcon nine rocket and crew Dragon capsule named Freedom

4:42 Speaker 1: have already been rolled out to the launch pad. The

4:44 Speaker 1: mission team plans to conduct rehearsal activities before moving the

4:47 Speaker 1: hardware back to the hangar to protect it from potential

4:50 Speaker 1: storm activity. As always, safety remains the top priority for

4:55 Speaker 1: both NASA and SpaceX. They'll continue to monitor the weather

4:59 Speaker 1: conditions closely and make further adjustments to the launch schedule

5:03 Speaker 1: if necessary. Next up, in a groundbreaking effort to understand

5:07 Speaker 1: the final moments of a satellite's life, the European Space

5:10 Speaker 1: Agency is gearing up for an exciting new mission called DRACO,

5:14 Speaker 1: short for Destructive re Entry Assessment Container Object. This project

5:19 Speaker 1: aims to capture never before seen data as a satellite

5:22 Speaker 1: breaks apart during re entry. For decades, we've watched satellites

5:26 Speaker 1: burn up in Earth's atmosphere, but we've never had a

5:29 Speaker 1: clear picture of exactly what happens during those final moments.

5:33 Speaker 1: Draco is set to change that. The mission will involve

5:37 Speaker 1: launching a specially designed satellite that mimics an average low

5:40 Speaker 1: Earth orbit satellite as it plummets back to Earth. It

5:44 Speaker 1: will collect crucial data on temperature, pressure, and strain. But

5:47 Speaker 1: here's the clever part. Inside this doomed satellite is an

5:51 Speaker 1: indestructible pod. This pod, equipped with sensors and cameras, will

5:55 Speaker 1: survive the fiery descent and transmit its valuable data back

5:58 Speaker 1: to Earth. It's like giving a saturate a black box recorder.

6:02 Speaker 1: This mission isn't just about scientific curiosity. The data collected

6:06 Speaker 1: will be invaluable for improving future satellite designs and enhancing

6:10 Speaker 1: our space debris mitigation strategies. As we continue to launch

6:14 Speaker 1: more satellites, understanding how to safely bring them down becomes

6:17 Speaker 1: increasingly important. Finally, today, let's return to an exoplanet that's

6:22 Speaker 1: fast becoming a friend here at Astronomy Daily. In an

6:25 Speaker 1: exciting breakthrough, astronomers have used NASA's James Web Space telescope

6:30 Speaker 1: to observe the atmosphere of a truly remarkable exoplanet known

6:34 Speaker 1: as WASP one oh seven B. This planet is not

6:37 Speaker 1: only incredibly hot, but also uniquely inflated. What makes this

6:40 Speaker 1: observation particularly groundbreaking is the discovery of an east west

6:45 Speaker 1: asymmetry in its atmosphere. This asymmetry means there's a significant

6:49 Speaker 1: difference between the eastern and western edges of the planet's atmosphere.

6:52 Speaker 1: It's the first time such a phenomenon has been observed

6:55 Speaker 1: in an exoplanet during its transit of its star. From space.

6:58 Speaker 1: This finding is crucial for understanding the climate, atmospheric dynamics,

7:03 Speaker 1: and weather patterns of worlds beyond our Solar system. WASP

7:06 Speaker 1: one oh seven B is a fascinating object. It's about

7:09 Speaker 1: the size of Jupiter, but only a tenth of its mass,

7:12 Speaker 1: resulting in an extremely low density. The planet is tidally

7:15 Speaker 1: locked to its star, meaning one side always faces the

7:18 Speaker 1: scorching heat while the other remains in perpetual darkness. Using

7:23 Speaker 1: a technique called transmission spectroscopy, researchers were able to capture

7:27 Speaker 1: detailed snapshots of the planet's atmosphere as it passed in

7:31 Speaker 1: front of its host star. These images reveal valuable information

7:34 Speaker 1: about the gases, clouds, and overall structure of the atmosphere.

7:38 Speaker 1: This discovery challenges some existing models and opens up new

7:41 Speaker 1: questions about how such a symmetry can exist on a

7:44 Speaker 1: planet like WASP one oh seven B. It's a testament

7:48 Speaker 1: to the power of the James Web Space Telescope and

7:51 Speaker 1: the ingenuity of astronomers in pushing the boundaries of our

7:54 Speaker 1: understanding of alien worlds. That's all for today's episode of
