On weekends, I love rockets.

20489
1547
00:22
I love photography, I love rockets.
2
22060

00:23
I'm going to talk about a hobby that can scale
3
23833
2158
00:26
and show you photos I've taken over the years
4
26015
2108
00:28
with kids like these, that hopefully will grow up to love rocketry
5
28147
3105
00:31
and eventually become a Richard Branson or Diamandis.

00:33
My son designed a rocket that became stable, a golf ball rocket.
7
33798
3009
00:36
I thought it was quite an interesting experiment
8
36831
2253
00:39
in the principles of rocket science.
9
39108
1742
00:40
And it flies straight as an arrow.
10

00:42
Baking soda and vinegar.

00:44
Night shots are beautiful,
12
44001
1310
00:45
piercing the Big Dipper and the Milky Way.
13

00:48
2-stage rockets with video cameras on them,
14
48886
2199
00:51
onboard computers logging their flights, rocket gliders that fly back to Earth.
15
51109
3778
00:54
I use RockSim to simulate flights before they go
16
54911
2243
00:57
to see if they'll break supersonic,
17
57178
1675
00:58
then fly them with onboard computers to verify performance.
18
58877
2821
01:01
To launch the big stuff, you go to the middle of nowhere:
19
61722
2677
01:04
Black Rock Desert, where dangerous things happen.
20
64423
2335
01:06
The boys and the rockets get bigger.
21
66782
1739
01:08
They use motors used on cruise-missile boosters.
22
68545
2611
01:11
They rumble the belly and leave even photographers in awe,
23
71180
2729
01:13
watching the spectacle.
24
73933
1151
01:15
These rockets use experimental motors like nitrous oxide.
25
75108
2786
01:17
They use solid propellant most frequently.
26

01:19
It's a strange kind of love.

RocketMavericks.com with my photos, if you want to learn about this,
28

participate, be a spectator.
29

1336
01:25
We had to call it Rocket Mavericks.
30
85898
1977
01:27
This one was great, went to 100,000 feet -- but didn't quite.
31
87899
2874
01:30
Actually, it went 11 feet into solid clay and became a bunker-buster.
32
90797
3277
01:34
It had to be dug out.
33
94098

01:35
Rockets often spiral out of control if you put too much propellant in them.
34
95546

01:39
Here was a drag race.
35

01:40
At night you can see what happened in a second;
36
100505
2240
01:42
in daytime, we call them land sharks.
37
102769
1772
01:44
Sometimes they just explode before your eyes or come down supersonic.
38
104565
3287
01:47
(Laughter)
39
107876
1009
01:48
To take this shot, I did what I often do, which is go way beyond the pads,
40
108909
3477
01:52
where none of the spectators are.
41
112410
1600
01:54
And if we can run the video, I'll show you what it took
42
114034
2580
01:56
to get this DreamWorks shot.
43

(Video) Voices: Woo-hoo! Yeah. Nice.
44

Steve Jurvetson: They realize the computer failed, they're yelling "Deploy!"
45
120690
3886
02:04
(Video) Man: Oh, shit.
46
124600
1151
02:05
SJ: This is when they realize everything's gone haywire.
47
125775
2629
02:08
(Video) Man: It's going ballistic.
48
128428
1621
02:10
SJ: I'll just be quiet.
49
130073
1151
02:11
(Video) Woman: No!
50
131248
1151
02:12
Come on, come on, come on.
51
132423
2000
02:18
SJ: And that's me over there, taking photos the whole way.
52
138330
2762
02:22
Things often go wrong.
53
142321
1151
02:23
Some people watch this because of a NASCAR-like fascination
54
143496
3273
02:26
with things bumping and grinding.
55
146793
1635
02:28
Burning the parachute as it fell. That was last weekend.
56
148452
2717
02:31
This guy went up, went supersonic, ripped the fin can off.
57
151193
2730
02:33
The art sale in the sky.
58
153947
1151
02:35
A burning metal hunk coming back.
59
155122
1579
02:36
These things dropped down from above all through the weekend
60
156725
2818
02:39
of rocket launch after rocket launch.
61
159567
1790
02:41
It's a cadence you can't quite imagine.
62
161381
1894
02:43
I try to capture the mishaps; it's a challenge in photography
63
163299
2876
02:46
when these things take place in a fraction of a second.
64
166199
2594
02:48
Why do it? For things like this:
65
168817

02:50
Gene from Alabama drives out there
66
170372
2147
02:52
with this rocket he's built with X-ray sensors, video cameras,
67
172543
3072
02:55
festooned with electronics.
68
175639
1291
02:56
He succeeds getting to 100,000 feet,
69
176954
1721
02:58
leaving the atmosphere, seeing a thin blue line of space.
70
178699
2680
03:01
It is this breathtaking image -- success, of course -- that motivates us
71
181403
3392
03:04
and motivates kids to follow and understand rocket science,
72
184819
2787
03:07
understand the importance of physics and math
73
187630
2104
03:09
and, in many ways, to have that awe at exploration
74
189758
2335
03:12
of the frontiers of the unknown.
75
192117
1534
03:13
Thank you.
