The arrival of tooling in the coming months is pivotal, setting the stage for spaceship final assembly to begin as planned. Looking back. In May twenty twenty four, Virgin Galactic inaugurated a ground testing facility in southern California, specifically designed for Delta subsystem testing. This facility focuses on crucial aspects like avionics, feather actuation, pneumatics and hydraulics using an iron Bird test rig to simulate real world conditions. The new Delta space ships are set to accommodate up to six private passengers, aiming to fly up to eight missions per month. This ambitious goal is part of Virgin Galactic's vision to significantly increase access to space, making it more achievable for those dreaming of a journey beyond Earth. With its state of the art features and robut us technological infrastructure, Virgin Galactic's new facility in Phoenix is not just a testament to innovation, but a beacon of the future of commercial space travel. Stay tuned as we watch this thrilling journey unfold, bringing us ever closer to the stars. The recent test flight of the SQX one y eight, a commercial carrier rocket from the Chinese private aerospace firm I Space, faced a significant setback. The rocket, also known as Hyperbola I, launched from the Juquan Satellite Launch Center in northwest China at seven forty am Beijing time. Unfortunately, shortly after liftoff, the rocket exhibited abnormal performance, leading to an unsuccessful mission. The SQX one y eight standing approximately twenty meters tall, is designed for the commercial satellite market and capable of delivering payloads up to two hundred and sixty kilograms to low Earth orbit. This setback comes as a significant blow to Beijing Interstellar Glory Space Technology Limited, the official name of eye Space, which is one of China's leading private space companies focusing on commercial rocket development and launches. Currently, an investigation is underway to determine the cause of the failure. The team at eyeSpace is conducting a detailed analysis to gain insights into the issues encountered during the flight. Understanding the root cause is crucial for the company to address these challenges and improve the reliability of their future missions. It's not uncommon for new advancements in space technology to face hurdles. Each setback provides valuable lessons that drive innovation and improvement, bringing us closer to the realization of commercial spaceflight goals. The continued efforts of private firms like eyeSpace highlight the increasing role that non government entities play in expanding our reach into space. As investigations proceed, the aerospace community will be eagerly awaiting the findings, hoping for swift resolutions and successful future launches. In other news, there's an exciting proposal that's been put forward by a group of planetary scientists that could redefine what we call a planet. Traditionally, as per the International Astronomical Union's two thousand and six definition, a celestial body must orbit our Sun to be classified as a planet. This has led to many debates as it excludes thousands of exoplanets orbiting other stars that have been discovered in recent years. Jean Luke Margo, a UCLA professor of Earth Planetary space sciences and physics, alongside his colleagues, is leading a charge to modernize this definition. Their innovative proposal, slated to be presented at the IAU General Assembly in August twenty twenty four, aims to create a more inclusive and precise classification system. The current definition describes a planet simply it must orbit the Sun, be massive enough for gravity to mold it into a spherical shape, and have cleared its orbit of other objects. While straightforward, this definition is limited in scope. It fails to consider the many celestial bodies that orbit stars beyond our Solar system, rendering our understanding somewhat archaic in the context of modern astrophysical discoveries, Margo and his team argue that a more universal definition is necessary. Their proposed criteria include requiring a planet to orbit any star, stellar, remnant or brown dwarf, not just our Sun. This shift acknowledges the reality of exoplanets planets that orbit stars other than the Sun, which are now known to be myriad across the galaxy. Additionally, they've suggested quantifiable limits for a planet's mass. According to their research, a body needs to be more massive than ten circumflex twenty three kilograms, but less massive than thirteen jupiter masses, beyond which point thermonuclear fusion occurs, transforming it into a brown dwarf. This mass range is significant because it helps distinguish planets from other types of celestial body more clearly. One of the most contentious parts of the existing definition is the requirement for a planet to have cleared its orbit. This concept is interpreted to mean that a planet is gravitationally dominant enough to either absorb or fling away smaller objects in its path. Margo and his co authors propose refining this by using dynamical dominance, a concept that more precisely describes how a planet interacts with its neighboring space. In their proposal, they also address problems with the current requirement for a planet to be spherical. Observationally, it's tough to confirm the shape of a distant object. Instead, they propose focusing on mass, since bodies meeting the lower mass limit of ten circumflex twenty three kilograms are generally spherical due to their gravity. This new definition aims to create a more practical and scientifically accurate understanding of planets. By anchoring the criteria to the most measurable quantity, Masso and his colleagues hope to eliminate much of the ambiguity that currently exists. They believe their definition, developed using rigorous mathematical algorithms, will serve as a robust framework for categorizing celestial bodies both within our Solar System and beyond. Though an official change by the IAU might be years away, this proposal is a crucial step towards an updated, comprehensive definition that keeps pace with our expanding knowledge of the universe. It underscores the importance of evolving scientific definitions to align with new discoveries and understandings. Let's dive into the recent anomaly experienced by SpaceX during the launch of their Starlink internet satellites. On Thursday night, July eleventh, SpaceX encountered a rare issue with its reliable workhorse, the Falcon nine rocket. The launch took place from Vandenberg Space Force Space in California and initially seemed to proceed without a hitchrocket's two stages separated right on time, and the first stage successfully landed on a drone ship about eight minutes after liftoff as planned. However, the anomaly occurred with the rocket's upper stage, which was tasked with deploying twenty Starlink spacecraft to low Earth orbit. According to Elon Musk, SpaceX's founder and CEO, the problem arose during the upper stage's restart to raise the peragy, a maneuver meant to adjust the orbit of the satellites. Musk took to social media stating that the upper stage experienced what they call a rapid Unscheduled disassembly or RUD, a term that the company uses to describe an explosion or a disintegration. This RUD prevented the second stage engine from completing its second burn, a critical step for deploying the satellites into their intended orbit. While the satellites were deployed, the parage, the point in their orbit closest to Earth, may be too low for them to stabilize on their own. An hour after Musk's in any, SpaceX released more information elaborating that the upper stage engine's failure led to the satellites being placed in a lower than intended orbit. As of now, SpaceX has made contact with five of the deployed satellites. Efforts are underway to use their onboard ion thrusters to raise their orbits to the desired altitude. Interestingly, during the launch webcast, observers noted an unusual build up of fluffy white material near the second stage Merlin engine while it fired in space. This sighting has led to speculation about a potential propellant leak, though SpaceX has yet to confirm or deny this theory. The Falcon nine rocket has an outstanding track record, with sixty nine launches already accomplished in twenty twenty four alone. Known for its reliability, the Falcon nine has suffered only one full in flight failure since its debut, which took place during a twenty fifteen mission, to launch a Dragon cargo capsule to the International Space Station. This incident underscores the unpredictability and challenges inherent in space travel, even for seasoned players like SpaceX. The Falcon nine is human rated and has successfully conducted thirteen crude missions, nine of which were to the ISS for NASA. Consequently, the root cause of this anomaly will need to be thoroughly analyzed and addressed to ensure future missions, both crude and uncrued, maintain the high standards of safety and reliability SpaceX is known for. Despite this hiccup, SpaceX continues to push the boundaries of what's possible in space technology. The twenty Starlink satellites launched are part of an ambitious plan to expand global Internet coverage, with thirteen of these new satellites designed to beam service directly to cell phones. The Starlink Mega constellation already boasts more than six thousy one hundred operational satellites, with forty nine of this year's sixty nine Falcon nine launches dedicated solely to Starlink missions. It's a reminder of the risks and the dynamic nature of space exploration. As SpaceX continues to investigate this latest anomaly. The focus remains on learning from each mission success or failure to improve future launches and ultimately make space more accessible for everyone. That brings us to the end of today's episode.
