SpaceX Starship rocket lost during 8th test flight, debris shoots through sky
SpaceX's eighth flight test of its Starship spacecraft ended with a 'rapid unscheduled disassembly,' the same wording Elon Musk's company used when Starship's January flight exploded in the sky. SpaceX's Starship rocket broke up during its eighth uncrewed flight test on Thursday, sending debris shooting through the sky and temporarily affecting flights at Miami-area airports. It was SpaceX's second such setback since January. SpaceX on Thursday lost communication with the rocket just over nine minutes after the launch. Elon Musk's company said the rocket "experienced a rapid unscheduled disassembly," the same language it used when Starship's last test flight in January unexpectedly exploded in the sky The 400-foot spacecraft, composed of both the Starship vehicle and Super Heavy rocket, launched just after 6:30 p.m. ET Thursday.The Federal Aviation Administration said in a statement to USA TODAY Thursday that it activated a debris response area and "briefly slowed aircraft outside the area where space vehicle debris was falling or stopped aircraft at their departure location." Greg Chin, a spokesman with the Miami-Dade Aviation Department, said that "some flights" were delayed at Miami International Airport between 7 and 7:30 p.m. ET "due to falling debris from the SpaceX launch over the Atlantic Ocean." The FAA said that normal operations resumed Thursday night night. As of 8:30 p.m. ET, the National Airspace System Status page listed a departure delay at Miami International due to "space launch debris," though the FAA said in a follow-up email that the airspace was open. Despite Thursday's setback, SpaceX was able to complete its third return and catch of the rocket booster at the launch pad, but it did not complete a Starlink payload deployment test. The Starship vehicle was intended to land in the Indian Ocean. "Obviously a lot to go through, a lot to dig through, and we're going to go right at it," SpaceX's Dan Huot said during the livestream of Thursday's launch. "We have some more to learn about this vehicle." More video of Starship test flight 8 after it exploded… from Jarod Long “Captured this while driving Southeast on Queens Hwy in Exuma Bahamas at 6:40pm ET. It was a lot more colorful than what shows up in the video.” Previous launch ended in fiery explosion The previous Starship demonstration on Jan. 16 ended in a fiery explosion after the Starship vehicle was lost during its suborbital flight. Mission controllers lost contact with the spacecraft within 8 1/2 minutes of its flight before determining that it was destroyed in what the company called a “rapid unscheduled disassembly.” Video on social media showed the explosion and its aftermath as remains of the spacecraft are seen breaking up in what looks like a stunning meteor shower.SpaceX, which conducted an investigation with the FAA, determined that the mishap was due to a series of propellant leaks and fires in the aft section of the vehicle that caused “all but one of Starship’s engines to execute controlled shut down sequences." This led to the communication breakdown and the vehicle to trigger its own self destruction.This story has been updated with new information Starship flew within a designated launch corridor to safeguard the public both on the ground, on water, and in the air. Following the anomaly, SpaceX teams immediately began coordination with the FAA, ATO (air traffic control) and other safety officials to implement pre-planned contingency responses.Approximately two and a half minutes into flight, the Super Heavy booster shutdown all but three of its Raptor engines as planned for hot-staging separation. Starship then successfully lit its six Raptor engines and separated from the Super Heavy booster to continue its ascent to space. The Super Heavy booster then relit 11 of 13 planned Raptor engines and performed a boostback burn to return itself to the launch site. As Super Heavy approached the launch site, it relit 12 of the planned 13 engines at the start of its landing burn to successfully slow the booster down. The three center engines continued running to maneuver the booster to the launch and catch tower arms, resulting in the third successful catch of a Super Heavy booster.

Starship launch: How to watch Elon Musk's SpaceX conduct latest rocket launch from Texas
SpaceX's massive Starship spacecraft is due to get off the ground again Monday evening from South Texas for the second time this year. The impending launch, which was pushed from Friday before the Federal Aviation Administration gave the green light, comes little more than a month since the previous flight test in January ended with the vehicle unexpectedly exploding in the sky. The most recent demonstration of the biggest and most powerful rocket ever built also included the successful return of the booster, known as the Super Heavy, at the launch pad.The 400-foot vehicle, composed of both the 165-foot Starship spacecraft and the 232-foot Super Heavy rocket, is being developed and tested before eventually being used on future crewed spaceflight missions. SpaceX envisions the spacecraft as being a fully reusable transportation system that will be vital for when NASA astronauts return to the moon, perhaps as early as 2027. SpaceX CEO Elon Musk has also made clear his ambitions for Starship to ferry the first humans from Earth straight to Mars. Here's how to watch the Starship test launch, and what to know about SpaceX's goals for the flight: SpaceX is planning to launch its Starship on Monday on its eighth flight test from the company's Starbase in Boca Chica near Brownsville, Texas. The launch window opens at 6:30 p.m. EST. How to watch SpaceX livestream SpaceX will host a livestream of the flight test that will begin about 40 minutes before liftoff. The webcast is available on its website and on social media platform X. Coverage will also be available on SpaceX's on new X TV app. "As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to check in here and stay tuned to our X account for updates," SpaceX said. SpaceX once again plans to attempt a third return and catch of the rocket booster at the launch pad, which would cause sonic booms in the area around the landing zone. The maneuver, which was first pulled off once during the October demonstration, was called off during the November launch, which then President-elect Donald Trump attended. The Starship vehicle itself is targeted to land once again in the Indian Ocean. However, SpaceX plans to conduct experiments geared toward one day returning the vehicle, known as the the upper stage, back to the launch site. In another objective, SpaceX will take a second shot at a Starlink payload deployment test – a key capability for the vehicle in the future that was called off during the previous launch. The four Starlink simulators, similar in size and weight to next-generation Starlink satellites, will be on the same suborbital trajectory as Starship and are expected to burn up on reentry.Additionally, the company plans to once again reignite its Raptor engines in space to attempt an orbital burn – a crucial maneuver to one day bring a vehicle back to the ground. Starship's Eighth Flight Test Starship’s eighth flight test lifted off from Starbase in Texas at 5:30 p.m. CT on Thursday, March 6. The Super Heavy booster successfully lit its 33 Raptor engines and propelled Starship through a nominal first-stage ascent. Approximately two and a half minutes into flight, the Super Heavy booster shutdown all but three of its Raptor engines as planned for hot-staging separation. Starship then successfully lit its six Raptor engines and separated from the Super Heavy booster to continue its ascent to space. The Super Heavy booster then relit 11 of 13 planned Raptor engines and performed a boostback burn to return itself to the launch site. As Super Heavy approached the launch site, it relit 12 of the planned 13 engines at the start of its landing burn to successfully slow the booster down. The three center engines continued running to maneuver the booster to the launch and catch tower arms, resulting in the third successful catch of a Super Heavy booster. Starship continued its ascent to its planned trajectory. Prior to the end of the ascent burn, an energetic event in the aft portion of Starship resulted in the loss of several Raptor engines. This in turn led to a loss of attitude control and ultimately a loss of communications with Starship. Final contact with Starship came approximately 9 minutes and 30 seconds after liftoff. Starship flew within a designated launch corridor to safeguard the public both on the ground, on water, and in the air. Following the anomaly, SpaceX teams immediately began coordination with the FAA, ATO (air traffic control) and other safety officials to implement pre-planned contingency responses. Any surviving debris would have fallen within the pre-planned Debris Response Area. There are no toxic materials present in the debris and no significant impacts expected to occur to marine species or water quality. If you believe you have identified a piece of debris, please contact your local authorities or the SpaceX Debris Hotline at 1-866-623-0234 or at [email protected]. With a test like this, success comes from what we learn, and today’s flight will help us improve Starship’s reliability. We will conduct a thorough investigation, in coordination with the FAA, and implement corrective actions to make improvements on future Starship flight tests.

The Future of Energy: China's Thorium Reserves and Their Net Worth
China's contempo analysis of all-inclusive thorium affluence has the abeyant to decidedly appulse the all-around activity landscape. Thorium, a hardly radioactive metal, is advised a able another to uranium in nuclear activity assembly due to its affluence and abeyant for safer reactor designs. This commodity explores the implications of China's thorium resources, their estimated value, and the broader ambience of thorium in the all-around activity sector. Understanding Thorium and Its Potential Thorium (Th) is a artlessly occurring radioactive aspect begin in baby amounts in best rocks and soils. It is about three to four times added abounding than uranium in the Earth's crust, authoritative it a potentially added acceptable ability for nuclear energy. Thorium-based reactors action several advantages over acceptable uranium reactors: Abundance: Thorium's greater availability could ensure a longer-term activity supply. Safety: Thorium reactors are advised to be inherently safer, with lower risks of meltdowns. Waste: They aftermath beneath abiding radioactive decay compared to uranium reactors. Proliferation Resistance: Thorium's by-products are beneath acceptable for weaponization, abbreviation admeasurement risks. China's Thorium Reserves: A Game Changer Recent letters announce that Chinese geologists accept apparent abundant thorium deposits. While the exact abstracts abide classified due to civic aegis considerations, estimates advance that these affluence could be amid the better globally. A civic analysis assured in 2020 and afresh declassified accent that China's thorium deposits may be decidedly beyond than ahead estimated. SCMP.COM Prior to this discovery, China's thorium affluence were estimated at about 100,000 tons. EN.WIKIPEDIA.ORG However, the new allegation advance that the affluence could be abundant larger, potentially accession China as a baton in thorium resources. Estimating the Bread-and-butter Value Determining the exact bread-and-butter amount of thorium affluence is arduous due to several factors: Market Demand: Currently, thorium has bound bartering applications, primarily in specialized industries. Its amount is carefully angry to its abeyant use in nuclear energy, which is still beneath development.

Earth Like Planets In Milky Way. AI-Generated.
Imagine a planet that is similar to Earth, where you could walk outside and breathe easily, and where water flows like it does on our planet. These planets are called Earth-like planets. To be considered Earth-like, a planet must have certain characteristics: 1. Size: It should be about the same size as Earth. 2. Composition: It should be made mostly of rock, like Earth. 3. Location: It must orbit its star at a distance where water can exist in liquid form. This area is called the habitable zone. 4. Star Type: Ideally, it should orbit a star similar to the Sun, which provides the right amount of light and heat. How Many Earth-like Planets Are There? Scientists have made many estimates about how many Earth-like planets might exist in the Milky Way. Some think there could be as many as **40 billion** Earth-sized planets in the habitable zones of stars. Of these, about **11 billion** might orbit stars similar to the Sun. Another estimate suggests there could be **8.8 billion** Earth-size planets orbiting Sun-like stars in the habitable zone. Notable Earth-like Exoplanets: While many planets have been discovered, only a few are considered truly Earth-like. Here are some examples: - Kepler-452b: This planet is about 60% larger than Earth and orbits a star similar to the Sun. It's located about 1,400 light-years from Earth. - TRAPPIST-1 System: This system has seven Earth-sized planets, with three of them (e, f, and g) in the habitable zone. However, these planets might not be as Earth-like as thought because their atmospheres could be different. Challenges in Finding Earth-like Planets: Finding Earth-like planets is difficult because they are small and far away. Current methods, like using the Kepler space telescope, have limitations. Future missions, such as the James Webb Space Telescope and the Habitable Exoplanet Imaging Mission (HabEx), aim to improve detection by studying the atmospheres of these planets for signs of life. Why Finding Earth-like Planets Matters: Discovering Earth-like planets raises big questions about whether life exists elsewhere in the universe. If there are billions of planets similar to Earth, it's more likely that life could exist on some of them. However, the **Fermi Paradox**—the lack of evidence for extraterrestrial civilizations—remains a mystery. Future Research: As technology improves, scientists will explore more of the Milky Way for potentially habitable worlds. Upcoming missions will focus on understanding the atmospheres of exoplanets, which could provide clues about their potential for supporting life. The search for Earth-like planets is not just about finding worlds like our own but also about understanding how unique or common life might be in the universe. Conclusion: The search for Earth-like planets in the Milky Way is an exciting area of research that continues to fascinate scientists and the public. With billions of potential Earth-like planets estimated to exist, the possibility of discovering life beyond Earth becomes more plausible. As we continue to explore and understand our galaxy better, we may uncover answers to some of humanity's most profound questions about our place in the universe. How Do Scientists Find Earth-like Planets? Scientists use several methods to find Earth-like planets: 1. Transit Method: This involves measuring the decrease in brightness of a star when a planet passes in front of it. The Kepler space telescope used this method to discover many exoplanets. 2. Radial Velocity Method: This method detects the slight wobble of a star caused by the gravitational pull of an orbiting planet. 3. Direct Imaging: This involves capturing images of planets directly using powerful telescopes. However, this method is challenging due to the brightness of the stars. What Does the Future Hold? Future missions will focus on characterizing the atmospheres of exoplanets. This can help determine if a planet has conditions suitable for life. For example, the presence of oxygen or methane in an atmosphere could indicate biological activity. The search for Earth-like planets is a journey that not only expands our understanding of the universe but also challenges our perspectives on life and its potential existence elsewhere.

Pope Francis remains stable after thanking public for prayers, Vatican says
LONDON and ROME -- Pope Francis' "overall condition remains stable within his complex medical situation and the prognosis remains reserved," the Vatican said Friday. The pope "spent about 20 minutes in prayer in his chapel on the 10th floor apartment and the rest of the day alternated between rest, physiotherapy, prayer and a bit of work," the Vatican said. He continues to use "high-flow oxygen therapy during the day and non-invasive mechanical ventilation at night as he has done these past days," according to the Vatican. The pope "had a tranquil night and woke shortly after 8 a.m." on Friday morning, the Vatican said, coming a day after he made his first public comments since being hospitalized on Feb. 14. The 88-year-old pope "remained stable compared to previous days" and did not have "episodes of respiratory insufficiency" on Thursday, his 21st day in the hospital, the Vatican said in its evening update. While Friday marks his 22nd consecutive day in hospital, the pontiff offered up hope on Thursday in the form of his first public comments since being hospitalized. "I thank you from the bottom of my heart for your prayers for my health from the Square, I accompany you from here. May God bless you and the Virgin protect you. Thank you," the pope said in a recorded statement made in Spanish. The statement was played at the start of the rosary in St. Peter's Square.

What if Earth suddenly stoped spinning?. AI-Generated.
If the Earth and all terrestrial objects suddenly stopped spinning while the atmosphere retained its velocity, the initial consequence would be catastrophic winds. At the equator, where the surface is moving at roughly 470 meters per second (over 1,000 mph), the air would continue at that speed. Since supersonic speed is 343 m/s, most of the world would experience winds exceeding that threshold. People living between 42° North and 42° South—about 85% of the global population—would face these devastating conditions. The winds would last for only a few minutes before friction slowed them down, but that would be long enough to demolish nearly all human structures. Even those in sturdy bunkers wouldn't be safe, as airborne debris would strike with immense force. The destruction would be unprecedented, reducing cities to rubble in moments.
