As a person who helped build and launch rockets for NASA's Space programs, I naturally became curious about seeing the 20th Century Fox motion picture, The Martian directed by Ridley Scott, starring Matt Damon.
The spectacular computer graphics effects and designs of the recent movies Interstellar and The Martian remind us that it is easy to get to Mars and beyond via fantasy technology, but real-world travel is still a hard nut to crack.
Space travel goes beyond the dreams of young students. It's also about each and every one of us here on Earth ... at this very moment. By committing to space exploration, we are making it known that we believe in the world that we live in right now.
Why is it that we are not further along with 'space travel' despite over 60 years of steady effort? It's very simple! For interstellar travel we have dreams but no technology, while for interplanetary travel we have technology but no dreams!
What if one day we encounter aliens, and they are our descendants?
Burt Rutan, the legendary aerospace engineer and designer of the Ansari XPRIZE-winning SpaceShipOne, explains how the achievement a couple of bicycle shop owners (Orville and Wilbur Wright) inspired the most significant individuals in the first century of aerospace.
We need to move beyond the "flags and footprints" missions and travel to space with the intent to stay, and Mars is our best bet. The good news is that the majority of the obstacles are economic, rather than engineering. The bad news is that it's a tough business case to close.
The allure of space travel and exploring the cosmos has enchanted tourists for decades. The Soviet Union's launch of Sputnik 1, an artificial satellite, in 1957 is credited with starting the "space race;" and the world's interest in space exploration skyrocketed.
In our Part I article, we mentioned how numerous scientists over the past 65 years, since Fermi first raised the question "Where is everybody?", have examined Fermi's paradox and have proposed solutions. There is still no easy answer.
Most people think that Star Trek-style nuclear rockets are a thing of the future, but the fact is we had them in the 1960s... and gave up on them.
Unless you call yourself a rocket scientist, you probably don't think your daily routine has much in common with flight software engineering. But you would be wrong. If you skip the bits about the flying, disregard the software and pay no attention to the engineering, then what you're left with is some amazingly useful life lessons.
Becoming an astronaut is easily the dream of many but sometimes that's all it ever is -- a dream. For Leland, who happens to be the 13th African American astronaut, that all became a reality through patience, hard work, and a knack for problem solving.
Navigation requires a reference frame. We need reference frames to tell us where we are with respect to other objects and we need reference frames to tell us how we are oriented with respect to other objects. There is no single universal frame that is used for all operations.
The 30th season of Survivor, premieres on February 25th. For 15 years, I have indulged in my guilty pleasure of watching castaways try to outwit, outlast and outplay each other for a million dollars.
Here you have it. In the next few centuries, we can colonize the solar system in any number of different ways using largely conventional technology extended to meet the reasonable challenges of week-long hope to Mars, Saturn or elsewhere.
In recent years, it seems that the allure of space has once again captured the minds of a generation.
