原來去年就發射了
多坐標軸的軌道真是奧妙 這樣居然是比較省燃料的路徑

重力彈弓

這是利用Weak Stability Boundary和Ballistic capture
Weak Stability Boundary效應:把衛星往日地的L1丟，但衛星能量不足以越過L1或停在L1，那衛星就會往地球返回，
在返回的過程中的能量向量不是單純的朝向地球，那衛星軌道的近地點可以提高到月球軌道的高度

Ballistic capture效應:如果在衛星到近地點時，剛好接近月球，那月球就可以把衛星留住，那就進入月球軌道了

你可以參考這YouTuber的解說

是利用重力，但不是利用重力彈弓效應
這是利用衛星、地、日、月之間的重力影響

舉手請問
這次無人登月部分成功定義是什麼?

>>1181519
有無線電專業的網友按照Hakuto-R最後傳回的無線電訊號的頻譜分析
很高機率是最後時刻出現問題，自旋後砸在月面上了

"We choose to go to the moon. We choose to go to the moon in
this decade and do the other things, not because they are
easy, but because they are hard, because that goal will
serve to organise and measure the best of our energies and
skills, because that challenge is one that we are willing to
accept, one we are unwilling to postpone, and one which we
intend to win, and the others, too."
- 美国总统约翰·菲茨杰拉德·肯尼迪 (1917-1963)

我有問題
為什麼日本的研究中心的日本人都長的外國臉

>>1181556
多國合作啊

覺得樣樣都要自己幹才有面子的那套已經不流行了

官方正式宣布Hakuto-R mission 1 失敗了
https://ispace-inc.com/news-en/?p=4655

ispace engineers monitored the estimated remaining propellant reached at the lower threshold and shortly afterward the descent speed rapidly increased. After that, the communication loss happened. Based on this, it has been determined that there is a high probability that the lander eventually made a hard landing on the Moon’s surface.

工程師發現在著陸的最後階段出現燃料不足引擎失效，降落速度增加，
導致"硬著陸"

For Mission 1, it has been determined that Success 9 (landing) of the Mission 1 Milestones, successfully landing on the Moon and establishing communications, is no longer achievable.

這是跨國民間公司，在東京、加州、盧森堡都有分公司

>>1181568
看來是沒算好燃料量？

>>1181569
可能性很多，也可能是引擎或導航控制出問題

>>1181571
>>1181569
印象中阿波羅11第一次上去,到著陸成功時燃料也沒剩幾秒可用了
生體電腦現場控制都這樣了

火星人: 不是我的错。

同志，登月是伪造的.
