The Redstone Rocket went straight up. But the capsule.... Didn't have enough speed to gointo orbit. So came back down. Essentially it's a triangle..Earth, sub-orbit, Earth. That math was known. That took Shepard,took Grissom. That cannot take Glenn. Now, The Atlas Rocket.. That can push us into orbit.It goes up delivers the capsuleinto an elliptical orbit. Earth's gravity keeps pulling it, but it's going so fast thatit keeps missing the Earth. That's how it stays in orbit. Now, Getting it back down... That's the math we don't know. Yes, Katherine So, the capsule will spinaround the Earth forever, because there's nothingto slow it down? That's right. Slowing it down at preciselythe right moment, by precisely the right amount That is the task

The Redstone Rocket went straight up
00:00:03.024 --> 00:00:04.029
But the capsule
00:00:04.051 --> 00:00:07.013
Didn't have enough speed to go into orbit So came back down
00:00:07.082 --> 00:00:10.093
Essentially it's a triangle Earth sub orbit Earth
00:00:11.031 --> 00:00:12.069
That math was known
00:00:12.077 --> 00:00:15.033
That took Shepard took Grissom
00:00:16.018 --> 00:00:18.999
That cannot take Glenn
00:00:18.092 --> 00:00:20.048
Now The Atlas Rocket
00:00:21.035 --> 00:00:24.355
That can push us into orbit It goes up
00:00:24.038 --> 00:00:27.294
delivers the capsule into an elliptical orbit
00:00:27.033 --> 00:00:28.668
Earth's gravity keeps pulling it
00:00:28.693 --> 00:00:31.998
but it's going so fast that it keeps missing the Earth
00:00:31.065 --> 00:00:33.998
That's how it stays in orbit
00:00:33.093 --> 00:00:35.075
Now Getting it back down
00:00:36.096 --> 00:00:38.076
That's the math we don't know
00:00:40.078 --> 00:00:41.094
Yes Katherine
00:00:41.095 --> 00:00:44.598
So the capsule will spin around the Earth forever
00:00:44.623 --> 00:00:46.654
because there's nothing to slow it down
00:00:47.022 --> 00:00:51.054
That's right Slowing it down at precisely the right moment
00:00:51.069 --> 00:00:53.033
by precisely the right amount
00:00:53.034 --> 00:00:54.047
That is the task

Movie Summary
The untold story of Katherine G. Johnson, Dorothy Vaughan and Mary Jackson – brilliant African-American women working at NASA and serving as the brains behind one of the greatest operations in history – the launch of astronaut John Glenn into orbit. The visionary trio crossed all gender and race lines to inspire generations to dream big.
