Starship's Fifth Flight Challenge, Mars Mission Rethink, and a Surprising Galaxy

0:00 Speaker 1: Welcome stargazers and space enthusiasts to another exciting episode of

0:04 Speaker 1: Astronomy Daily. I'm your host, Anna, and I'm thrilled to

0:07 Speaker 1: bring you the latest and greatest developments from the Cosmos. Today,

0:11 Speaker 1: We've got a stellar lineup of space news to explore.

0:13 Speaker 1: We'll be blasting off with updates on SpaceX's Starship, the

0:16 Speaker 1: next giant leap in space exploration. We'll also dive into

0:19 Speaker 1: some fascinating discoveries that are challenging our understanding of the

0:23 Speaker 1: early universe, from Mars sample return missions to the search

0:28 Speaker 1: for distant exoplanets. We'll cover the cutting edge research that's

0:33 Speaker 1: expanding our cosmic horizons, and we'll even touch on the

0:36 Speaker 1: growing need for space rescue capabilities as more humans venture

0:40 Speaker 1: beyond Earth's atmosphere. So strap in and prepare for launch

0:45 Speaker 1: as we embark on this cosmic journey through the latest

0:48 Speaker 1: in space exploration and astronomy. Let's get started. SpaceX is

0:53 Speaker 1: gearing up for another exciting milestone in their Starship development program.

0:57 Speaker 1: The company is preparing for the fifth test flight the

1:00 Speaker 1: massive Starship vehicle, with a potential launch date as soon

1:03 Speaker 1: as October thirteenth. This upcoming mission is particularly noteworthy as

1:07 Speaker 1: it will mark the first attempt at catching the super

1:09 Speaker 1: heavy booster. For those who may not be familiar, Starship

1:13 Speaker 1: is SpaceX's next generation, fully reusable launch system, designed to

1:17 Speaker 1: carry both crew and cargo to Earth orbit, the Moon, Mars,

1:21 Speaker 1: and beyond. It consists of two main components, the Starship

1:25 Speaker 1: spacecraft itself and the super heavy booster that provides the

1:28 Speaker 1: initial thrust to get off the ground. In previous test flights,

1:31 Speaker 1: we've seen SpaceX make significant progress with Starship's capabilities. They've

1:36 Speaker 1: demonstrated controlled descents, multiple engine relights, and even a successful

1:40 Speaker 1: water landing. However, this fifth flight will push the envelope

1:43 Speaker 1: even further. The most ambitious aspect of this upcoming test

1:47 Speaker 1: is the planned attempt to catch the super heavy booster.

1:50 Speaker 1: Instead of landing on legs or a drone ship like

1:52 Speaker 1: Falcon nine boosters, SpaceX aims to use the launch tower

1:55 Speaker 1: itself to catch the massive first stage. This technique, if success,

2:00 Speaker 1: could greatly streamline the turnaround process for reusing boosters. While

2:04 Speaker 1: SpaceX has set an ambitious target date, it's important to

2:07 Speaker 1: note that this launch is still pending regulatory approval. The

2:11 Speaker 1: company will need to secure the necessary clearances from the

2:13 Speaker 1: Federal Aviation Administration before proceeding with the test flight. As

2:18 Speaker 1: with all developmental test flights, there's no guarantee of success. However,

2:21 Speaker 1: each attempt provides valuable data and lessons that SpaceX can

2:25 Speaker 1: use to refine and improve the Starship system. The company's

2:29 Speaker 1: iterative approach to testing has proven effective in the past,

2:32 Speaker 1: and space enthusiasts around the world will be eagerly watching

2:35 Speaker 1: to see what new milestones might be achieved with this

2:38 Speaker 1: fifth flight. The Federal Aviation Administration is currently reviewing SpaceX's

2:43 Speaker 1: launch license application for the upcoming Starship test flight. However,

2:47 Speaker 1: this process hasn't been without its share of controversy and confusion. Initially,

2:52 Speaker 1: the FAA had stated they didn't expect to make a

2:54 Speaker 1: determination on the license before late November. This timeline didn't

2:58 Speaker 1: align with SpaceX's ms ambitious plans, as the company has

3:02 Speaker 1: been indicating readiness to launch since August. In a surprising

3:05 Speaker 1: turn of events, recent reports suggests the FAA could potentially

3:09 Speaker 1: approve the license as soon as this month. This sudden

3:12 Speaker 1: shift has raised eyebrows and sparked debates within the space community,

3:16 Speaker 1: adding to the complexity space s CEO Elon Musk has

3:19 Speaker 1: been vocal in his criticism of the FAA. He's called

3:23 Speaker 1: for the resignation of FAA Administrator Mike Whittaker and even

3:26 Speaker 1: threatened legal action over the perceived delays. The FAA, for

3:30 Speaker 1: its part, has cited concerns over SpaceX's compliance with regulations.

3:34 Speaker 1: At a recent congressional hearing, Whittaker mentioned that SpaceX had

3:38 Speaker 1: failed to complete a timely sonic boom analysis for the

3:41 Speaker 1: Starship launch, which contributed to the delay as we await

3:45 Speaker 1: the final decision. This situation highlights the delicate balance between

3:49 Speaker 1: innovation in the commercial space sector and the need for

3:52 Speaker 1: thorough safety oversight. It's a process that will likely continue

3:56 Speaker 1: to evolve as private companies push the boundaries of space exploration.

4:01 Speaker 1: Several upcoming launches are currently on hold as SpaceX investigates

4:04 Speaker 1: a recent anomaly with the Falcon nine second stage. This

4:08 Speaker 1: incident occurred during the Crew nine mission, where the stage

4:11 Speaker 1: landed outside its designated zone following re entry on September

4:14 Speaker 1: twenty eighth. One of the affected missions is the highly

4:17 Speaker 1: anticipated Europa Clipper. NASA and SpaceX had initially planned to

4:22 Speaker 1: launch this probe to Jupiter's moon Europa on October tenth,

4:25 Speaker 1: using a Falcon Heavy rocket. However, due to Hurricane Milton

4:29 Speaker 1: approaching Florida, they've postponed the launch to October twelfth, at

4:32 Speaker 1: the earliest weather permitting. The Europa Clipper mission is particularly

4:37 Speaker 1: challenging even for the powerful Falcon Heavy in its fully

4:40 Speaker 1: expendable configuration. At six thousand and sixty five kilograms, the

4:45 Speaker 1: probe is one of the heaviest interplanetary payloads ever launched.

4:49 Speaker 1: It will embark on a five and a half year

4:50 Speaker 1: journey to Jupiter, using gravity assists from Mars and Earth

4:55 Speaker 1: to adjust its trajectory. Another mission affected by the Falcon

4:59 Speaker 1: nine investigationation is the one Web flight, which was originally

5:03 Speaker 1: scheduled to launch from Vandenberg Space Force Base in California.

5:07 Speaker 1: This would have been the twentieth launch for the one

5:09 Speaker 1: Web Internet constellation, aiming to place twenty satellites into a

5:12 Speaker 1: polar orbit. While these missions are delayed due to the

5:16 Speaker 1: second stage anomaly, it's worth noting that the Europa Clipper

5:19 Speaker 1: launch isn't directly impacted by this investigation. Its delay is

5:23 Speaker 1: primarily due to the approaching hurricane. Other launches in the

5:26 Speaker 1: pipeline include potential starlink missions and various commercial and government payloads. However,

5:31 Speaker 1: specific details and timelines for these launches remain uncertain until

5:35 Speaker 1: the Falcon nine investigation concludes and SpaceX receives the necessary

5:39 Speaker 1: approvals to resume its regular launch cadence. As we await

5:43 Speaker 1: further updates, it's clear that ensuring launch vehicle reliability and

5:47 Speaker 1: safety remains a top priority for SpaceX and NASA, even

5:50 Speaker 1: if it means temporary delays to high profile missions. In

5:54 Speaker 1: a surprising discovery that's challenging our understanding of the early universe,

5:59 Speaker 1: astronomers have a galaxy that looks remarkably similar to our

6:02 Speaker 1: own Milky Way, but from a time when the Cosmos

6:05 Speaker 1: was just a baby. This galaxy, named Rebels twenty five,

6:09 Speaker 1: is observed as it appeared about seven hundred million years

6:12 Speaker 1: after the Big Bang. To put that in perspective, the

6:15 Speaker 1: universe is currently estimated to be about thirteen point eight

6:18 Speaker 1: billion years old, so we're looking at a galaxy from

6:21 Speaker 1: when the universe was only about five percent of its

6:24 Speaker 1: current age. What's truly astounding about Rebels twenty five is

6:27 Speaker 1: its structure. Unlike the chaotic, messy formations we typically expect

6:31 Speaker 1: to see in early galaxies. This one shows signs of

6:34 Speaker 1: being a well ordered, rotating disc. It may even have

6:37 Speaker 1: a central bar and spiral arms, though further observations are

6:41 Speaker 1: needed to confirm these features. This level of organization is

6:44 Speaker 1: something we usually associate with much more mature galaxies. Current

6:48 Speaker 1: theories suggest it should take billions of years for galaxies

6:51 Speaker 1: to settle into such orderly structures. Finding one so early

6:54 Speaker 1: in the universe's history is forcing astronomers to rethink their

6:58 Speaker 1: models of galaxy formation and evolution. The discovery was made

7:02 Speaker 1: using the Atacama Large Millimeter Submillimeter Array or ALMA, a

7:06 Speaker 1: powerful radio telescope in Chile. This finding underscores how much

7:10 Speaker 1: we still have to learn about the early universe and

7:13 Speaker 1: how quickly cosmic structures can form and evolve. As we

7:16 Speaker 1: continue to push the boundaries of our observations, looking further

7:19 Speaker 1: back in time and space, we may need to revise

7:22 Speaker 1: our understanding of how the first galaxies came to be Rebels.

7:26 Speaker 1: Twenty five is a cosmic rebel, indeed, defying our expectations

7:30 Speaker 1: and opening up new questions about the universe's earliest days.

7:35 Speaker 1: NASA is ramping up efforts to explore alternative concepts for

7:38 Speaker 1: the ambitious Mars sample return mission, with the goal of

7:41 Speaker 1: reducing costs and accelerating the timeline. The agency has awarded

7:46 Speaker 1: several contracts to study new approaches, including one to rocket Lab,

7:50 Speaker 1: which was not part of the initial selection but was

7:53 Speaker 1: later added due to its innovative proposal. Rocket Lab's concept

7:57 Speaker 1: aims to deliver samples collected by the Perseverance Road to

8:00 Speaker 1: Earth for a fraction of the currently projected costs, which

8:04 Speaker 1: are estimated to be as high as eleven billion dollars.

8:07 Speaker 1: Their plan involves using their Neutron rocket, currently in development

8:11 Speaker 1: along with other spacecraft projects. The company proposes a simplified

8:15 Speaker 1: mission architecture, targeting a total cost to NASA of less

8:18 Speaker 1: than two billion dollars. Their aggressive timeline suggests a twenty

8:23 Speaker 1: twenty eight launch window, potentially returning samples as early as

8:27 Speaker 1: September twenty thirty one or no later than September twenty

8:30 Speaker 1: thirty three. This would significantly reduce the risks associated with

8:34 Speaker 1: the Perseverance Rovers lifetime on Mars. Other companies involved in

8:39 Speaker 1: the study contracts include Blue Origin, which is leveraging its

8:41 Speaker 1: commercial capabilities and NASA support for its Blue Moon Lunar Lander.

8:46 Speaker 1: Aerojet Rocketdyne is focusing on reducing the mass of both

8:49 Speaker 1: the Mars ascent vehicle and its lander, potentially allowing for

8:54 Speaker 1: the use of existing skycrane landing technology. Space X, unsurprisingly,

8:59 Speaker 1: is a exploring how its starship vehicle could be utilized

9:02 Speaker 1: for the mission, though details remain scarce. These industry studies,

9:07 Speaker 1: along with internal assessments by NASA's Jet Propulsion Laboratory and

9:10 Speaker 1: the Applied Physics Lab, are expected to be completed this fall.

9:14 Speaker 1: The agency will use the findings to determine how to

9:17 Speaker 1: modify the current Mars sample return architecture to achieve its

9:21 Speaker 1: cost reduction and timeline acceleration goals. NASA Administrator Bill Nelson

9:26 Speaker 1: has expressed optimism about these efforts, stating that the prospects

9:30 Speaker 1: for a much cheaper and quicker Mars sample return mission

9:33 Speaker 1: are looking very promising. As the studies conclude and NASA

9:37 Speaker 1: evaluates the proposals, we may soon see a reimagined approach

9:41 Speaker 1: to bringing the first samples from Mars back to Earth,

9:43 Speaker 1: potentially revolutionizing our understanding of the Red planet. When more

9:48 Speaker 1: people venture into space, experts are raising concerns about our

9:51 Speaker 1: ability to rescue astronauts in distress. The United States currently

9:55 Speaker 1: lacks a dedicated, go get them capability for in space

9:58 Speaker 1: rescue missions, a worrying reality as commercial spaceflight continues to expand.

10:04 Speaker 1: Grant Kates, a senior project leader at the Aerospace Corporation,

10:08 Speaker 1: emphasizes that we need to address this gap before an

10:10 Speaker 1: emergency occurs, not after. He argues that the US has

10:14 Speaker 1: the technology and resources to establish space rescue capabilities, but

10:18 Speaker 1: lacks the planning and urgency to make it happen. The

10:20 Speaker 1: recent issues with Boeing's Starliner spacecraft highlight the potential risks

10:25 Speaker 1: even for relatively simple missions to the International Space Station.

10:29 Speaker 1: As private crews take on more ambitious endeavors like high

10:32 Speaker 1: altitude spacewalks and lunar missions, the need for rescue capabilities

10:36 Speaker 1: becomes even more critical. Experts suggest that a modest investment

10:40 Speaker 1: could get the ball rolling on developing these capabilities. A

10:43 Speaker 1: small study office to scope out the details of in

10:46 Speaker 1: space rescue could be a feasible first step. Some believe

10:49 Speaker 1: that industry could take voluntary actions to put at least

10:51 Speaker 1: a partial rescue capability in place. Ultimately, congressional legislation may

10:56 Speaker 1: be needed to authorize a lead agency and appropriate funding

10:59 Speaker 1: for a comprehensive space rescue program. While not all emergencies

11:02 Speaker 1: can be resolved with a rescue, having these capabilities in

11:05 Speaker 1: place could mitigate risks and potentially save lives as we

11:09 Speaker 1: continue to push the boundaries of human spaceflight. In exciting

11:14 Speaker 1: news for the search for habitable worlds beyond our Solar system,

11:17 Speaker 1: researchers have developed a new method to detect atmospheres on

11:20 Speaker 1: distant exoplanets using the James Web space telescope. This breakthrough

11:25 Speaker 1: could significantly advance our ability to identify potentially life supporting planets.

11:29 Speaker 1: The technique, demonstrated by University of Chicago researchers, compares an

11:32 Speaker 1: exoplanet's actual temperature to its theoretical maximum temperature. Since atmospheres

11:37 Speaker 1: distribute heat around a planet, worlds with atmospheres tend to

11:40 Speaker 1: have cooler hot sides than those without. Using the Web

11:44 Speaker 1: telescopes enhanced infrared capabilities, scientists can now measure exoplanet temperatures

11:49 Speaker 1: with unprecedented precision. By observing how a planet's heat signature

11:53 Speaker 1: changes as it orbits its star, researchers can deduce whether

11:56 Speaker 1: an atmosphere is present. This method offers several advantages of

12:00 Speaker 1: previous techniques. It's simpler, more efficient, and less prone to

12:04 Speaker 1: false results that can be caused by factors like stellar

12:07 Speaker 1: activity or cloud cover. The team applied this approach to

12:10 Speaker 1: the exoplanet gj Oney one hundred and thirty two B,

12:14 Speaker 1: concluding it likely lacks an atmosphere. While this particular world

12:18 Speaker 1: isn't a candidate for life, the technique opens up new

12:21 Speaker 1: possibilities for surveying other rocky planets. As we gather data

12:25 Speaker 1: on more exoplanets, scientists hope to uncover patterns in atmosphere

12:29 Speaker 1: formation and retention. This knowledge will be crucial in our

12:32 Speaker 1: quest to understand what makes a planet truly habitable and

12:36 Speaker 1: where we might find potential cradles for life in the cosmos.

12:40 Speaker 1: And that brings us to the end of today's episode

12:43 Speaker 1: of Astronomy Daily. I hope you've enjoyed this journey through

12:46 Speaker 1: the latest developments in space exploration in astronomy, from SpaceX's

12:50 Speaker 1: upcoming starship launch to groundbreaking discoveries about ancient galaxies, it's
