🤖 AI Summary

中国が月基地建設を計画し、これにより米国が緊急の反応を示しています。米上院議員テッド・クルースは「21世紀の宇宙競争」だとしており、CNNも長年にわたって背景にあった競争が再び前面に出ていると指摘しています。

中国は2040年まで月面に永久的な居住施設を建設する計画があることから、米国議員らは新たな宇宙競走を宣言し、NASAも自国の月基地建設を約束しています。両国とも今年度末に月極点周辺の探査ロボットを送り込む計画です。

中国の「嫦娥7号」ミッションが最短で今月内に打ち上げられ、複数の機動車(オービター、着陸器、rovers およびホッパー)を用いたデータ収集を目指しています。このミッションは月面水素の探査にも挑戦します。

中国と米国ともに月極点を中心に活動が増加しており、国際法がないため競争はますます激しくなっています。クレイトン・スウォープは、宇宙基地が「街」になり人間が長期的に居住する未来があることを期待しています。

一方で、NASAには月面着陸能力の機器がないという問題も浮上しています。アポロ計画の成功を再現することなく新たな探査活動に取り組む必要があります。

中国は2004年以来 lunar 探査計画に焦点を当て、中央集権的な計画システムを利用して特定の目標に向かって資源を流用してきました。一方で、米国は月面基地建設に核発電所の設置も視野に入れており、ロシアとの協力が有望な可能性があります。

宇宙空間における法整備や月でのリソース利用規制など、これらの活動には多大な法的・組織的な課題があることが指摘されています。
"We are in a 21st century space race," U.S. Senator Ted Cruz has said. And this week CNN noted a competition that for decades loomed in the background of geopolitics "is now roaring to the forefront," with China "demonstrating rapid advances in space technology" while the U.S. is "ratcheting up rhetoric about a looming battle for control of the cosmos." It's the fact that China plans to build a permanent settlement on the moon by 2040 that has prompted an urgent response from [U.S.] lawmakers... They've declared a new space race, and NASA is pledging to build a lunar outpost of America's own.... Both the United States and China plan to send robotic explorers to the south pole later this year, paving the way for human explorers to follow close behind. The US is relying on the private sector to develop and build low-cost, exploratory robotic landers... Meanwhile, China is aiming to launch its robotic Chang'e-7 mission as soon as this month. The complex endeavor will seek to use four different robotic vehicles — an orbiter, lander, rover and mobile "hopper" — working in tandem to attempt to gather unprecedented data. The effort will include tools to drill for and directly analyze water ice, a feat that the US will only attempt with robotic missions slated for next year at the earliest. "If lunar water ice is successfully located, it could significantly reduce the cost and time required to transport water from Earth, facilitating the establishment of a human base for long-term activities on the moon and enabling further exploration of Mars or deep space," Tang Yuhua, the deputy chief designer of the Chang'e-7 mission, said in a 2025 interview with state media. The oncoming flurry of south-pole-centric activity, with few established international laws to govern the outcomes, is heightening the drama of this rivalry... But with a much more ambitious goal — a future in which people attempt to flourish within permanent settlements rather than just visit the moon — the stakes of this new space race are even higher, according to Clayton Swope, the deputy director of the Aerospace Security Project at the Center for Strategic and International Studies, a bipartisan nonprofit. "The long-term vision will take generations to execute on," Swope said. "But in my mind, it's a scenario where there are people being born, people dying, their families, children growing up in a place that is not Earth — so that looks a lot like a city, more than it looks like an expedition to the south pole." If such a future comes to fruition, Swope added, his hope is that such extraterrestrial colonies would be governed by rules reminiscent of Western ideals and democratic principles. Whether China would be on the same page is an open question. China is already fine-tuning its plans for a lunar settlement, CNN writes: The country envisions the International Lunar Research Station, or ILRS, as a sprawling science-focused facility on the moon's surface that can be operated robotically, "with the prospect of subsequent human presence," according to a government's ILRS website. China could partner with Russia to build a massive nuclear reactor to power the base, though questions remain regarding how the war in Ukraine may impact Russia's ability to deliver... China and Russia were mapping these plans long before the US announced its own intention to build a nuclear reactor on the moon last year and detailed its plans for a lunar settlement spanning hundreds of square miles... Who will write the rules? And how, exactly, will the use of lunar resources be policed on the international stage? Meanwhile, NASA "still does not have a vehicle capable of getting astronauts down to the lunar surface," the article points out: Returning to the moon is not as simple as repeating Apollo. The space agency cannot — and does not wish to — replicate its 20th century lunar-landing success. The supply chains, skilled machinists and factories that built Apollo's rockets, landers and command modules no longer exist. And while the Apollo landings stuck close to the lunar equator, landing near the south pole is substantially more complex and requires more powerful vehicles.... China, meanwhile, has been laser focused on its lunar exploration program since 2004, using its top-down, central planning system to keep resources flowing toward specific goals.

NASAの Lunar Reconnaissance Orbiter は次の週に同地域を通過し、詳細な撮影を行う予定です。この事件は宇宙探査における意図外の事故の一例であり、今後その管理や危険回避について更なる検討が必要であるとの意見が挙げられています。
A South Korean lunar orbiter has captured the first before-and-after images of the Moon's crash scene caused by a stray SpaceX Falcon 9 rocket. The Associated Press reports: The Korea Aerospace Research Institute's Danuri spacecraft flew over the impact site soon after the Falcon 9 upper stage inadvertently plowed into the moon on Wednesday. Danuri made multiple passes, snapping photos from lunar orbit that were released by the space agency Thursday. The terrain is noticeably darker where the rocket hit and carved out a crater, sending dust and rock everywhere. Korean space officials said Danuri gathered before and after shots. NASA expects its Lunar Reconnaissance Orbiter to fly over the crash site next week to view the aftermath. You can view the images here.

スペースXのフェルnanカ9上面部が2025年の月惑星ミッション後、地球大気中に再入して燃え尽きるか海洋に落下する代わりに、月へ向けて軌道に留まる予定です。この4トンもの上面部は約5,400マイル/時でエインシュタイン・カレット付近に衝突すると予想されます。同ミッションのために余分な推進力を必要としたため、2段目がスペースに滞在し、数千の他の宇宙ごみと混ざりあって浮遊していました。これはおそらく小規模な科学的興味を引き出すかもしれませんが、「SpaceXのNASA科学およびDragonプログラム部長」ジュリアナ・シェミアンは報じています。「これは誰にも危険ではないが、廃棄される残骸(宇宙ごみ)の処理に対する一定の粗雑さを示している。」ビリー・グレイ氏は広く利用されている天文ソフトウェアの作成者で、4月に上面部の衝突について報告しました。YouTubeでの生中継を通じて、地球からは難しいかもしれませんが、光で照らされた月塵の噴出が見られるかもしれません。
A four-ton SpaceX Falcon 9 upper stage left drifting after a 2025 lunar mission is expected to crash into the Moon at about 5,400 mph, likely striking Einstein Crater. The impact should occur at approximately 2:35 a.m. ET (0635GMT). Reuters reports: Such stages typically fall back into Earth's atmosphere and burn up or plunge into the ocean after boosting the rocket's payload to a precise spot in orbit. But because the January lunar lander mission required more thrust than missions closer to Earth, the rocket's second stage remained in space, floating aimlessly among thousands of other pieces of space junk that active satellites must steer clear of. It was not until earlier this year that astronomers determined that the rocket stage, which had dumped its remaining fuel and cannot be controlled, was on an orbital trajectory ending at the moon. "What has happened is essentially a mixture of solar activity and gravity forces have put it on a path toward the moon," Julianna Scheiman, SpaceX director of NASA science and Dragon programs, told reporters on Monday. "This may be of some -- probably minor -- scientific interest, and we may learn some things from it," said Bill Gray, creator of widely used astronomy software who published a report on the stage's impact in April. "It doesn't present any danger to anyone, though it does highlight a certain carelessness about how leftover space hardware (space junk) is disposed of." You can try to watch the impact via a livestream on YouTube; however, the area it's expected to hit (Einstein Crater) is on the moon's western limb, "which is often difficult to see from Earth," notes Reuters. It will also likely "kick up a plume of lunar dust that will likely be illuminated by sunlight but difficult to spot with the naked eye from Earth."

"Space.com and The Guardian are reporting that the Falcon 9 upper stage leftover from the launch of the Firefly Blue Ghost-1 lander on Jan. 15, 2025 is due to impact the Moon on Aug. 5, 2026," writes longtime Slashdot reader fahrbot-bot. From a report: Onboard the same flight was the Hakuto-R Mission 2, called Resilience, a robotic lunar lander developed by the Japanese company ispace. According to a new study by an international team, the resulting impact plume may briefly be bright enough to see against the dark sky near the moon's edge. That means it might be visible to moongazers with sufficiently sensitive telescopes. This head-on collision of the errant stage is expected to occur near the Einstein and Bell craters near the western lunar limb. It may well be visible to ground and space-based assets. Using special physics simulations to model the impact, William Jo, a graduate research assistant at the University of Texas, Austin and colleagues predict the debris plume from the impact will have the central ejecta spike reaching roughly 47 miles to over 60 miles (75 kilometers to 100 kilometers) altitude. "Our calculations suggest the plume should be several orders of magnitude brighter than the dark-sky background for the first few minutes after impact," Jo told Space.com. "So the plume should be visible, though I'd stress this is a single nominal case. The real one will look different, and the numbers are on the optimistic side. But the point worth making is that the flash isn't really the story here." Jo emphasized that there's great slam-dunk science to be had. "Watching this one gives us a rare chance to open up ejecta-plume science and calibrate those models against a real event, which matters for every future thing we deliver to the moon," Jo said.
