萤火虫航天公司计划于3月2日尝试一项雄心勃勃的壮举,将“蓝色幽灵”号宇宙飞船降落在月球近侧的克里西姆盆地。这次任务是NASA商业月球有效载荷服务计划的一部分,携带了一系列仪器和实验,为NASA建立永久月球基地做准备。尽管中国和印度最近取得了成功,但月球着陆仍然充满挑战,因为月球几乎没有大气层来减缓宇宙飞船的速度。如果一切按计划进行,“蓝色幽灵”号的下降过程将持续一个小时,并预计在着陆后进行14天的科学操作。这次任务的成功将为未来的载人登月任务奠定基础,NASA计划在2027年将宇航员送上月球。

⚙️ 月球着陆的挑战在于月球几乎没有大气层来减缓宇宙飞船的速度,宇宙飞船必须精确地降落在月球表面,通过推进器减速,避开陨石坑。此前,美国的“奥德修斯”号着陆器在2024年着陆时受损,日本的着陆器也倒置着陆。

⏳ 如果一切顺利,“蓝色幽灵”号的下降过程将持续一个小时,如果没有损坏,预计该探测器将进行14天的科学操作。

Over a half-century after astronauts walked on the moon, landing remains a daunting endeavor.

On March 2, Texas-based Firefly Aerospace will attempt the ambitious feat, as it will direct its robotic Blue Ghost spacecraft to land in Mare Crisium, a lava-covered basin on the moon's near side. The company has shared some of the mission's final views before descending to the lunar surface, showcasing the "magnificent desolation” NASA astronaut Buzz Aldrin witnessed in 1969.

In the clip below, sped up by 10x, you're seeing the crater-blanketed moon from 62 miles above, with the craft's thruster at top center.

"That feeling you get when you look out the window and realize you're almost home! T-4 days until we land [on] the Moon," Firefly Aerospace posted on X on Feb. 26.

The 6.6-foot-tall lander, funded by NASA as part of its Commercial Lunar Payload Services program, is carrying a suite of instruments and experiments for the space agency as NASA prepares to establish a permanent presence on the moon. This includes radiation-tolerant computing tests and sampling of the lunar regolith.

But landing on the moon remains daunting, largely because it's a world with virtually no atmosphere to slow spacecraft down. A craft must plummet to the surface perfectly, as thrusters fire to slow its descent onto a surface teeming with pits and craters. Although Chinese and Indian craft have had recent landing successes, the U.S. commercial spacecraft Odysseus sustained damage while landing awkwardly in 2024. The same year, a Japanese craft landed upside down, on its head.

If all goes as planned, Blue Ghost's looming descent will take just an hour. If it lands without damage, the craft is expected to perform science operations for 14 days.

Crucially, human spaceflight is expected to follow these robotic missions. NASA currently intends to fly astronauts to the moon in mid-2027, wherein they'll spend a week exploring the dark, shadowy craters of the moon's south pole.
