It all started with a Big Bang. But then what?

Renowned theoretical astrophysicist Stephen Hawking had been trying to answer that and other questions about the universe right up until his death. But in his final paper, submitted just eight days before he died on March 14, at age 76, Hawking and co-author Thomas Hertog proposed that the universe is actually simpler than what’s been suggested in other theories.

NASA Langley researchers are experts in modeling and simulations for entry, descent and landing, working on missions since the Viking lander in 1976. In this episode, we explore the challenges of guiding landers like Mars InSight through the Martian atmosphere for a safe landing. Watch InSight launch as early as May 5, 2018!

The battlefields of the future look set to be the province of robots duking it out on the field as their operators sit pretty, miles away. Russia is moving in leaps and bounds towards fielding its own unmanned forces.

Modern robots are nothing like the Terminator: Fielding human-shaped automatons for combat is much more trouble than it’s worth, so most ground robots are more or less tank- or car-shaped. They aren’t fully controlled by an artificial intelligence, either – not just yet, at least.

With its enormous war budgets and military industrial sector, it’s no surprise the US has been at the forefront of unmanned combat vehicle development. Its Predator drones have been raining death on Pakistan, Afghanistan and Yemen for over 15 years now, and it has been employing small, ground-based firing platforms like SWORDS for years, not to mention the multitude of bomb disposal and surveillance robots.

On a recent BBC World Service program (News Hour Extra, 12.18.15), a group of space scientists were gathered to discuss these and other aspects of the post-human era. “What about the human soul”, the moderator asked, wondering whether or not these post-humans would still be human. None of the participants were particularly troubled by the question, since they all had assumed that the soul was no more than the particular configurations of DNA which resulted in varying degre…es of insight, intelligence, creativity, and sensitivity. Post-humans will be no different, they all agreed. Only their individual genomes will have been altered to produce a very different human reality – in other words a different human soul.


Once the human genome was completely sequenced; once efforts to recombine DNA had become a reality; and once a mind-computer interface had been realized, there was never any doubt that a post-human era was coming.
