and how the bearings in the waist move.

And by comparing natural body motion to suited body motion

00:26:03,200 --> 00:26:05,248
we can start to tweak the design of the suit

00:26:07,320 --> 00:26:10,244
So that's what we're focusing on for exploration--

392
00:26:10,320 --> 00:26:12,971
is how do you walk, how do you bend, how do you kneel,

there was dirt everywhere--there was dirt on themselves.

400
00:26:47,160 --> 00:26:49,162
It was just gross, right?

00:26:58,520 --> 00:27:00,682
specifically, to breathe in for long periods of time,

403
00:27:00,760 --> 00:27:02,683
so, long-duration missions,we wouldn't want to

404
00:27:02,760 --> 00:27:05,081
bring that dirt inside with us all the time.

00:28:34,080 --> 00:28:37,971
astronauts may make test missions to nearby asteroids.
宇航员可能对附近的小行星执行试验任务

427

00:29:39,320 --> 00:29:41,322
and only decompress once

00:30:21,880 --> 00:30:26,124
and reposition a small asteroid to orbit our moon.
并重新定位一颗小行星环绕月球运行

446
00:30:28,360 --> 00:30:30,169
This would allow for easier study,

447
00:30:30,240 --> 00:30:33,562
and also develop our ability to deflect a larger asteroid
