SpaceX's Secretive Launch, China's Laser Constellation, and NASA's Mars Roadmap: S03E232

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

0:02 Speaker 1: in astronomy news. Today, we have an exciting lineup of

0:05 Speaker 1: stories from across the space industry. We'll look at a

0:08 Speaker 1: mysterious SpaceX mission that was scrubbed at the last minute

0:11 Speaker 1: that's generating buzz in the space community, explore China's ambitious

0:15 Speaker 1: new satellite constellation project, and dive into NASA's latest plans

0:19 Speaker 1: for getting humans from the Moon to Mars. Plus, we'll

0:23 Speaker 1: examine fascinating new research about the possibility of Moon's orbiting

0:26 Speaker 1: planets around binary star systems, and more. There's a lot

0:29 Speaker 1: to cover, so let's get started. SpaceX has once again

0:33 Speaker 1: captured the space community's attention, this time with their enigmatic

0:37 Speaker 1: RT one mission from Florida's Cape Canaveral Space Force Station.

0:42 Speaker 1: While the launch was ultimately scrubbed due to high winds,

0:45 Speaker 1: it's the mysterious nature of the payload that has everyone talking.

0:50 Speaker 1: The mission details are unusually sparse, even by SpaceX standards.

0:54 Speaker 1: While many space observers believe RRT one will carry an

0:57 Speaker 1: advanced GPS satellite, specifically GPS three ten, SpaceX has remained

1:03 Speaker 1: tight lipped about the payload. The company hasn't even explained

1:06 Speaker 1: what the rrt IE designation means if it's an acronym

1:10 Speaker 1: at all. Adding to the intrigue, the payload faring that's

1:14 Speaker 1: the nose cone that protects the satellite during launch, lacks

1:17 Speaker 1: any of the usual artwork or logos we typically see

1:20 Speaker 1: on SpaceX missions. This departure from normal practices has only

1:24 Speaker 1: fueled more speculation about the mission's true nature. When the

1:28 Speaker 1: launch does proceed, the plan calls for the Falcon nine's

1:31 Speaker 1: first stage to return for a landing on the Drone

1:34 Speaker 1: ship a short fall of gravitas in the Atlantic Ocean

1:37 Speaker 1: about eight and a half minutes after liftoff. The booster

1:41 Speaker 1: isn't new to spaceflight, this will be its fourth mission.

1:44 Speaker 1: As for the payload, it's scheduled for deployment into orbit

1:47 Speaker 1: approximately ninety minutes after launch, though exactly what orbit remains

1:52 Speaker 1: another piece of this intriguing puzzle. Meanwhile, on the other

1:57 Speaker 1: side of the world, in a significant development for China

2:00 Speaker 1: space program, a long March two D rocket successfully launched

2:04 Speaker 1: five new satellites early Thursday morning from the Juquan Satellite

2:07 Speaker 1: Launch Center. These satellites form what's being called the High

2:11 Speaker 1: Speed Laser Diamond Constellation test system, marking an important step

2:15 Speaker 1: forward in China's space capabilities. The launch utilized a Yunjang

2:19 Speaker 1: three restartable upper stage to precisely position the satellites in

2:24 Speaker 1: three distinct orbits. Space tracking has confirmed that one satellite

2:28 Speaker 1: now occupies an orbit between nine hundred and eighty eight

2:32 Speaker 1: and one thousand, one hundred and sixty kilometers, another sits

2:36 Speaker 1: between seven hundred and ninety one and eight hundred and

2:39 Speaker 1: twelve kilometers, while the remaining three orbit at approximately nine

2:43 Speaker 1: hundred seventy five to nine hundred ninety kilometers above Earth.

2:48 Speaker 1: While specific details about the satellites remain limited, their designation

2:53 Speaker 1: suggests their designed to test advanced inter satellite laser communication links.

2:58 Speaker 1: This technology could prove crucial for China's ambitious mega constellation projects,

3:03 Speaker 1: including their National Gang constellation and the Shanghai backed Chanfan

3:08 Speaker 1: also known as the Thousand Sales constellation. This laser communication

3:12 Speaker 1: capability could help address one of China's key space challenges,

3:16 Speaker 1: their limited global ground station coverage. By enabling satellites to

3:20 Speaker 1: communicate directly with each other using laser links, they could

3:23 Speaker 1: significantly improve their network's effectiveness and reduce reliance on ground stations.

3:29 Speaker 1: This launch marks China's sixty third orbital launch attempt of

3:33 Speaker 1: twenty twenty four, putting them on track to potentially surpass

3:36 Speaker 1: their national record of sixty seven launches set just last year.

3:41 Speaker 1: With several more launches scheduled before year's end, including what

3:45 Speaker 1: could be the first Guwang Mega constellation satellites, China continues

3:49 Speaker 1: to demonstrate its growing prominence in space exploration and technology development.

3:55 Speaker 1: NASA has just released a comprehensive update to their Moon

3:58 Speaker 1: to Mars architecture, providing fresh insights into their ambitious plans

4:02 Speaker 1: for deep space exploration. The new documents outline a methodical

4:06 Speaker 1: approach to establishing a sustained human presence on the Moon

4:10 Speaker 1: while preparing for the ultimate goal of sending astronauts to Mars.

4:14 Speaker 1: One of the most notable revelations is NASA's decision to

4:18 Speaker 1: use nuclear fission as the primary power source for future

4:21 Speaker 1: Mars missions. This choice makes perfect sense given the challenging

4:25 Speaker 1: Martian environment. Unlike solar power, nuclear fission won't be affected

4:29 Speaker 1: by the planet's dust storms or the day night cycle,

4:33 Speaker 1: providing reliable, consistent energy for long term operations. The agency

4:37 Speaker 1: has also added two crucial new elements to their lunar

4:41 Speaker 1: infrastructure plans. First, they're developing a dedicated lunar surface cargo

4:46 Speaker 1: lander designed to deliver essential supplies, scientific equipment, and communication

4:51 Speaker 1: systems to the Moon. Second, they're planning and initial lunar

4:55 Speaker 1: surface habitat that will enable larger crews to stay on

4:58 Speaker 1: the Moon for extended periods, significantly expanding our capabilities for

5:02 Speaker 1: lunar exploration and research. These updates reflect NASA's careful, staged

5:07 Speaker 1: approach to deep space exploration. They're not just rushing to

5:11 Speaker 1: plant flags, they're building the foundation for permanent human presence

5:14 Speaker 1: beyond Earth. The agency is working closely with industry partners,

5:19 Speaker 1: academic institutions, and international collaborators to ensure their plans are

5:23 Speaker 1: both ambitious and achievable. This methodical planning process includes a

5:28 Speaker 1: new prioritized list of key architecture decisions that need to

5:31 Speaker 1: be made early in the planning stages for Mars missions.

5:35 Speaker 1: By identifying these critical decision points now, NASA can better

5:39 Speaker 1: coordinate its technology development efforts and ensure their investing resources

5:43 Speaker 1: in the most important areas for future mission success. In

5:47 Speaker 1: an exciting development from Tufft's University researchers have been investigating

5:52 Speaker 1: whether moons could exist around planets that orbit two stars.

5:56 Speaker 1: This groundbreaking study addresses a fascinating question about the complex,

6:00 Speaker 1: exity and diversity of planetary systems beyond our solar system.

6:04 Speaker 1: The research team used advanced computer simulations to model how

6:07 Speaker 1: exo moons might orbit what we call circumbinary planets, planets

6:12 Speaker 1: that circle two stars instead of one. What makes this

6:15 Speaker 1: particularly intriguing is that these binary star systems might actually

6:19 Speaker 1: offer more opportunities for potentially habitable worlds than we previously thought.

6:24 Speaker 1: Their simulations revealed that thirty to forty percent of stable

6:28 Speaker 1: moons in these systems could exist within the habitable zone,

6:31 Speaker 1: that sweet spot where conditions might be right for liquid

6:34 Speaker 1: water to exist on a surface. This is particularly significant

6:38 Speaker 1: because while many circumbinary planets we've discovered are gas giants,

6:42 Speaker 1: their moons could be Earth sized and potentially suitable for life.

6:46 Speaker 1: The study found that there are indeed stable orbits where

6:49 Speaker 1: moons could exist in these complex systems. This stability is

6:53 Speaker 1: crucial because it means these moons could persist long enough

6:57 Speaker 1: for life to potentially develop. The research specifically looked at

7:01 Speaker 1: different planetary configurations and determined what they call the hill radius,

7:07 Speaker 1: essentially the gravitational sphere of influence where a planet could

7:10 Speaker 1: keep its moons in stable orbits. While we haven't yet

7:14 Speaker 1: confirmed the existence of any exa moons, this research suggests

7:18 Speaker 1: that binary star systems might be promising places to look

7:22 Speaker 1: for them. The study also indicates that the best candidates

7:26 Speaker 1: for finding these moons would be systems where the two

7:29 Speaker 1: stars are widely separated, as this provides more stable conditions

7:33 Speaker 1: for both planets and their potential moons. Here's something to

7:37 Speaker 1: look forward to Early next year, NASA is gearing up

7:40 Speaker 1: for an exciting new mission to study our Sun. The

7:43 Speaker 1: PUNCH mission, which stands for Polarimeter to Unify the Corona

7:47 Speaker 1: and Heliosphere, is scheduled for launch in February twenty twenty

7:50 Speaker 1: five aboard a SpaceX Falcon nine rocket from Vandenberg Space

7:54 Speaker 1: Force Space. This innovative project will deploy four small satellites

7:58 Speaker 1: working together to capture unprecedented three D views of the

8:01 Speaker 1: Sun's corona and study how it transforms into the solar wind.

8:05 Speaker 1: The mission represents a significant step forward in our understanding

8:09 Speaker 1: of solar activity and space weather. With teams from the

8:12 Speaker 1: Southwest Research Institute leading the charge from both San Antonio

8:15 Speaker 1: and Boulder. Punch won't be traveling alone. It's hitching a

8:19 Speaker 1: ride alongside NASA's a SPHEREx observatory, making efficient use of

8:23 Speaker 1: the launch vehicle. Meanwhile, Virgin Galactic is expanding its horizons

8:27 Speaker 1: beyond US borders. The company has signed a promising agreement

8:30 Speaker 1: with Italy's Civil Aviation Authority to explore operating their suborbital

8:34 Speaker 1: space planes from Grottagli Airport in southern Italy. This collaboration

8:39 Speaker 1: marks a significant step toward establishing Virgin Galactic's first spaceport

8:43 Speaker 1: outside the United States. The project will unfold in two phases,

8:47 Speaker 1: with the first phase focusing on technical and operational requirements

8:51 Speaker 1: through twenty twenty five. This includes evaluating everything from potential

8:55 Speaker 1: flight paths to infrastructure needs. The Italian government has our

9:00 Speaker 1: already shown their commitment by allocating seventy million euros for

9:04 Speaker 1: spaceport infrastructure development. While actual flights from Italy are still

9:08 Speaker 1: several years away, Virgin Galactic isn't slowing down. They're currently

9:13 Speaker 1: focused on building their Delta class space planes, with assembly

9:17 Speaker 1: of the first vehicle scheduled to begin in early twenty

9:20 Speaker 1: twenty five at their new Phoenix facility. This expansion into

9:24 Speaker 1: Italy represents an exciting step toward making space tourism truly

9:28 Speaker 1: global and now a great example of astronaut ingenuity at

9:33 Speaker 1: work from the depths of space. Aboard the International Space Station,

9:37 Speaker 1: NASA astronaut Don Pettit has taken space photography to new

9:40 Speaker 1: heights with an innovative solution to a complex problem. Using

9:45 Speaker 1: his engineering expertise, Pettit created a homemade star tracker that's

9:48 Speaker 1: allowing him to capture breathtaking images of the Cosmos like

9:52 Speaker 1: never before. When you're orbiting Earth at seventeen thoy five

9:56 Speaker 1: hundred miles per hour, taking clear photos of stars typically

9:59 Speaker 1: was results in streaky, blurred images, but Pettit's ingenious device

10:04 Speaker 1: rotates the camera to match the ISS's ninety minute orbital period,

10:08 Speaker 1: compensating for the station's rapid movement. This allows for longer

10:13 Speaker 1: exposure times, revealing countless stars and celestial objects that would

10:17 Speaker 1: otherwise be impossible to photograph clearly from the space station.

10:21 Speaker 1: The results are spectacular, crystal clear images showing thousands of

10:25 Speaker 1: stars against the backdrop of Earth with our planet's distinct

10:29 Speaker 1: orange atmospheric glow, providing a stunning contrast. While the Earth

10:34 Speaker 1: appears intentionally blurred in these long exposures, the stars remain

10:37 Speaker 1: perfectly focused, offering an unprecedented view of the Cosmos from

10:41 Speaker 1: our orbital outpost. This isn't Pettit's first innovation aboard the ISS.

10:46 Speaker 1: During his previous stays, he invented the zero G coffee cup,

10:50 Speaker 1: which became the first patented invention in space. That creation

10:54 Speaker 1: solved the seemingly simple but technically challenging problem of drinking

10:58 Speaker 1: beverages normally in microgravity, rather than through pouches and straws.

11:04 Speaker 1: His latest photographic innovation continues this tradition of creative problem solving,

11:09 Speaker 1: pushing the boundaries of what's possible in space photography and

11:12 Speaker 1: demonstrating how astronaut ingenuity can advance our ability to document

11:16 Speaker 1: and study the universe around us. Well, that's all for
