Hello, everyone. I'm Steele McGonigal. And I'm Cara O'Brien. Welcome to this special 00:00:00
edition of Destination Tomorrow. On this episode, we'll be focusing on NASA's 00:00:11
new exploration plans to travel to the Moon, Mars and beyond. In recent months, NASA planners 00:00:15
have been preparing for a new initiative that will set a pioneering vision for NASA's exploration 00:00:21
programs. To prepare for this vision, NASA researchers are developing a step-by-step 00:00:25
process that will enable us to reach this goal in a safe and economical way. First by 00:00:30
using robotic missions as a testbed, then gradually moving into human missions, NASA 00:00:35
is paving the way for a human presence on other worlds in the next few decades. This 00:00:40
new NASA vision will help us carry on the basic human desire to explore. 00:00:44
From the earliest discoverers to our modern travelers, every step taken from the known 00:00:48
into the unknown has helped to feed this exploration instinct. One of the most important 00:00:53
agencies ever formed to help meet this need is NASA, or the National Aeronautics and Space 00:00:58
Administration. Obviously, exploration has been one of the cornerstones of the NASA mission 00:01:03
throughout its existence. Over the years, the talented men and women of NASA have changed 00:01:08
our world for the better, making exciting discoveries that have not only furthered the 00:01:14
space program, but have also transformed our daily lives here on Earth. In fact, for 00:01:18
every dollar NASA spends in space, at least $7 is returned to the public by way of inventions 00:01:23
and discoveries. This investment return can be seen in everyday technologies, ranging 00:01:28
from cordless power tools, cancer research, to weather prediction. Over 30,000 inventions 00:01:34
and discoveries have been made as a direct result of NASA's involvement. 00:01:40
Although NASA has done a great job pushing the envelope of exploration in space and back 00:01:44
here on Earth, there is still much more that needs to be done. Even with great public support 00:01:49
to reach our exploration goals, few people understand the challenges we'll face in getting 00:01:53
to other worlds. To help us better understand the technical and environmental problems we'll 00:01:58
encounter, researchers will first plan to test the waters by increasing our robotic 00:02:02
presence throughout the universe. These robotic missions will expand our knowledge base and 00:02:07
help us focus training that will prepare humans for the next step of exploration. Now 00:02:12
to help us understand how this will work, Jennifer Pulley spoke with Mark Saunders at 00:02:16
NASA Langley Research Center to find out more. 00:02:19
