我不是问 Gravity Assist 的原理 - deadmeat (962 bytes) 2007-11-13, 12:57:50 (182532)
- In that NASA site, it says already that currently no rocket - steven (56 bytes) 2007-11-13, 13:21:04 (182543)
  - ok 那以后中土就以这个为目标吧 - deadmeat (64 bytes) 2007-11-13, 14:39:07 (182574)
    - well, you can use ion engine to do that, even to 100km/s. - steven (49 bytes) 2007-11-13, 16:25:11 (182638)
- JPL的太阳系探测普遍采用gravity assist，肯定有其道理 (无内容) - JZ (0 bytes) 2007-11-13, 13:03:14 (182533)
我还是没明白计算天王星轨道的时候没必要考虑多体问题（至多加上海王星影响） - Amsel (101 bytes) 2007-11-13, 10:51:15 (182460)
- What you are thinking is not a n-body, but a 1-body problem - 008 (609 bytes) 2007-11-13, 12:50:38 (182528)
  - no quit right. 2-body problem means that two objects, - steven (1249 bytes) 2007-11-13, 13:36:22 (182548)
  - 俺昨天看了Steven的帖子以为这是多体问题 - Amsel (115 bytes) 2007-11-13, 13:08:43 (182536)
- For 嫦娥, a restricted 3-body problem should be enough. - steven (497 bytes) 2007-11-13, 11:31:08 (182479)
- 多体问题也不是那么困难 - eddie (106 bytes) 2007-11-13, 10:59:27 (182463)
