commercial resupply services mission to

9
00:00:29,109 --> 00:00:27,039
the international space station for nasa

10
00:00:30,550 --> 00:00:29,119
the spacecraft arrived at the station

11
00:00:32,310 --> 00:00:30,560
the next day

12
00:00:34,150 --> 00:00:32,320

cargo dragon delivered critical

20
00:00:50,950 --> 00:00:48,960
materials to support dozens of science

21
00:00:52,709 --> 00:00:50,960
and research investigations some of

22
00:00:54,549 --> 00:00:52,719
these include a protein crystal growth

23
00:00:55,990 --> 00:00:54,559
study that could improve how cancer

24
00:00:58,630 --> 00:00:56,000

25
00:01:00,310 --> 00:00:58,640
patients and a handheld bioprinter that

26
00:01:02,790 --> 00:01:00,320

27
00:01:04,630 --> 00:01:02,800
directly onto wounds for faster healing

28
00:01:05,990 --> 00:01:04,640

00:01:10,789 --> 00:01:08,159
laboratory before it returns to earth

31
00:01:13,190 --> 00:01:10,799
with research and return cargo splashing

32
00:01:15,190 --> 00:01:13,200
down off the coast of florida

33
00:01:17,350 --> 00:01:15,200
this launch capped off nasa's busiest
