伊隆馬斯克的星艦助推器世界第一

Elon Musk's Starship rocket has achieved a remarkable milestone by successfully capturing part of itself during its fifth test flight. The launch took place at sunrise from Texas, and the lower half of the rocket, known as the Super Heavy booster, was caught by a pair of giant mechanical arms as it returned to the launch pad. This event marks a significant advancement for SpaceX, the company behind Starship, as they aim to develop a fully reusable rocket system. SpaceX engineers celebrated the successful landing, declaring it 'a day for the history books. ' Before the launch, there were concerns that the booster might not be caught and could instead land in the Gulf of Mexico, highlighting the challenges of rocket recovery. The journey of the Starship rocket has not been without its setbacks. Less than a year ago, during its inaugural flight, the rocket was destroyed shortly after takeoff. However, SpaceX views these failures as essential learning experiences that contribute to their development strategy. By launching early and embracing the possibility of failure, they can gather valuable data and improve their technology more rapidly than their competitors. The fifth test flight followed a similar pattern to previous attempts, with the booster separating from the main rocket approximately two and three-quarter minutes after liftoff. After separation, the booster began its descent back to the launch site in Boca Chica, Texas. As the booster approached landing, the SpaceX team conducted final checks to ensure everything was in order. When the flight director gave the green light for landing, cheers erupted from the mission control room. The company had established thousands of criteria that needed to be met for the landing attempt to proceed. As the Super Heavy booster re-entered the atmosphere, its 33 raptor engines worked diligently to slow it down from speeds exceeding several thousand miles per hour. When it neared the landing tower, which stands at an impressive height of 146 meters (480 feet), it appeared to float gracefully before being caught by the mechanical arms. This successful capture occurred approximately seven minutes after the rocket's launch. Meanwhile, the Ship portion of the rocket, which is designed to carry equipment and crew for future missions, ignited its engines after separating from the booster and successfully landed in the Indian Ocean about forty minutes later. Elon Musk expressed his satisfaction on social media, stating, 'Ship landed precisely on target! Second of the two objectives achieved. ' Not only did the Ship land accurately, but SpaceX also managed to preserve some of the vehicle's hardware, which was an unexpected bonus. The ability to catch the booster instead of having it land on the pad reduces the need for complex ground equipment and allows for quicker redeployment of the rocket in the future. SpaceX has ambitious plans for the Starship rocket, envisioning it as a vehicle that will eventually transport humans to the Moon and Mars, making humanity a 'multi-planetary' species. NASA, the United States space agency, is also pleased with the successful flight, as they have invested $2. 8 billion in SpaceX to develop Starship into a lunar lander capable of returning astronauts to the Moon's surface by 2026. This timeline is relatively short in the context of space exploration, and SpaceX is eager to relaunch the rocket as soon as possible. However, the Federal Aviation Administration (FAA), the government body responsible for approving all rocket flights, has stated that no launches will occur before November while they review SpaceX's permits. Recently, the FAA and Elon Musk have been engaged in a public dispute after the agency announced it would fine SpaceX $633,000 for allegedly failing to adhere to its licensing conditions and not obtaining permits for previous flights. Before granting a launch license, the FAA assesses the potential environmental impact of the flight. In response to the fine, Musk threatened legal action against the FAA, and SpaceX has pushed back against claims of environmental pollution. Currently, the FAA primarily considers the immediate environmental effects of rocket launches, but there are broader implications of emissions that need to be addressed. Dr. Eloise Marais, a professor of atmospheric chemistry and air quality at University College London, noted that while carbon emissions from rockets are relatively low compared to other forms of transportation, there are other pollutants that are not being adequately considered. She highlighted that black carbon is a significant concern, as the Starship rocket uses liquid methane, a relatively new propellant, and there is limited data on its emissions. Dr. Marais explained that the black carbon released by rockets is particularly troubling because it is emitted at high altitudes, where it can persist longer in the atmosphere than emissions from airplanes.
