BOULDER, Colorado – Humans have been exploring outer space since April 1961 with the pioneering flight of Soviet cosmonaut Yuri Gagarin.
Today, several nations are making new plans to launch human beings back to the moon, then onward to Mars and perhaps beyond. But will that pursuit be short-circuited by the fast-paced merger of artificial intelligence (AI) and advanced humanoid robots?
That proposition was broached during a Humans to Titan Summit, held here June 11-12, a first-time event attended by specialists seeking to send astronauts to Titan, Saturn’s largest moon. It is an attractive, attention-getting place in space. Titan comes with a thick atmosphere and is a distinctive world of clouds, rain, rivers, lakes and seas of liquid hydrocarbons like methane and ethane. But will humans ever set foot on Titan, or will AI-powered advanced robots make the voyage instead?
Exciting and futile
The Humans to Titan Summit was both exciting and futile, said Pascal Lee, chairman of the Mars Institute and a planetary scientist at the SETI Institute. He is also director of the NASA Haughton-Mars Project at NASA Ames Research Center.
“The futile part comes from the fact that humans going to Titan is a longer-term goal in an age where technology is evolving so quickly,” Lee told Space.com. “But it has to be done and it’s worth doing as it gives us some sense of direction.”
Lee’s central position is that a human trek to Titan would be decades in the future. No surprise there.
“Meanwhile there’s a revolution that’s taking place on Earth,” he said, the emergence of android robots imbued with AI, innovations that are brewing and maturing relatively quickly.
Artificial super intelligence
“Everyone is aspiring to achieve artificial ‘general’ intelligence. However, we’re nearing the moment where AI is no longer narrow and focused on specific tasks to a point where it essentially matches human intelligence.
“Artificial ‘super intelligence,'” said Lee, “is actually having the complexity and subtleties of human thinking,” he said.
Whether such an android would have a soul or be self-aware, Lee said that’s more speculative. “But it certainly can get to the point where it becomes a very objective observer and scientist.”
Doesn’t take a visionary
“Android robots have exceeded in many ways the performance of many humans,” said Lee. “They can run, jump, do acrobatics, and with AI it doesn’t take a visionary to see that you essentially get an artificial human,” he said.
A multi-tasking android robot doesn’t need to be fed, nor breathe or sleep, and doesn’t produce its own waste, Lee said. “It has all the usefulness of a human being and none of the risks and shortcomings, along with the cost of sending humans. It automatically becomes your best exploration system,” he said, “and behaves like a biological human, but minus the biology. That’s our future in space.”
In the meantime, robotics is making strides.
So much so that having a robot look like a human is no longer strictly science fiction. In terms of the physical performance of robots, Lee senses “the race is on” between China and the United States.
Training ground
In fact, Lee points to a humanoid robot offered by China’s UBTech Robotics, the Walker S2. It can change its own depleted battery, swapping it out with a fresh, fully-charged battery.
That skill mimics mortality, Lee said, with the Chinese firm calling it another step toward fully autonomous machines capable of working 24/7.
Noting the NASA Haughton-Mars Project — an analog field research effort situated on Devon Island in the Arctic — Lee said that site could be used as a training ground for how humans and android robots can team up together.
“My hope is that on Devon Island we could start working with AI and ‘able-to-learn’ android robots. You could train an android robot to be a field assistant,” said Lee.
Circling back to Titan, Lee envisions that once an android-installed infrastructure on that distant Saturnian moon is set up, humans could make an official visit to the facility, completely run by robots.
“I think, ultimately, we think of Titan as the next big leap beyond Mars. But to me Titan is even more interesting as the last leap before interstellar travel,” Lee concluded.
