A test flight of a commercial carrier rocket from I-Space has failed

M 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 one, launched from the Zhuquan Satellite Launch center in northwest China at 07:40 a.m. beijing time. Unfortunately, shortly after liftoff, the rocket exhibited abnormal performance, leading to an unsuccessful mission. The SQX one Y eight, standing approximately 20 meters tall, is designed for the commercial satellite market and capable of delivering payloads up to 260 low earth orbit. This setback comes as a significant blow to Beijing Interstellar glory. Space Technology Limited, the official name of ispace, 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 ispace 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 ispace 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 of hoping for swift resolutions and successful future launches.


A new proposal could redefine what we call a planet

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 2006 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 Luc Margot, a UH 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 2024, 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, Margot 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 23 kg, but less massive than 13 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 bodies. 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. Margot 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 23 kg 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 mass, Margot 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, um, importance of evolving scientific definitions to align with new discoveries and understandings.


SpaceX experienced an anomaly during the launch of their Starlink Internet satellites

Let's dive into the recent anomaly experienced by SpaceX during the launch of their Starlink Internet satellites on Thursday night, July 11, SpaceX encountered a rare issue with its reliable workhorse, the Falcon Nine rocket. The launch took place from Vandenberg Space Force base in California and initially seemed to proceed without a hitch. The rocket'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 20 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 perigee, 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 burnt, a critical step for deploying the satellites into their intended orbit. While the satellites were deployed, the perigee, the point in their orbit closest to Earth, may be too low for them to stabilize on their own. An hour after Musk's initial post, 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 buildup 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 come confirm or deny this theory, the Falcon Nine rocket has an outstanding track record, with 69 launches already accomplished in 2024 alone. Known for its reliability, the Falcon Nine has suffered only one full in flight failure since its debut, which took place during a 2015 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 13 crewed 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 crewed and uncrewed, 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 20 Starlink satellites launched are part of an ambitious plan to expand global Internet coverage, with 13 of these new satellites designed to beam service directly to cell phones. The Starlink mega constellation already boasts more than 6100 operational satellites, with 49 of this year's 69 Falcon nine launches dedicated solely to Starlink missions. It's a reminder of the risks and the dynamic nature of space exploration. As, uh, 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.
