Feb. 15 (UPI) — The U.S. National Aeronautics and Space Administration on Wednesday indicated that President Donald Trump may want the United States to resurrect its pioneering spirit in outer space — much the same way another American leader did five decades ago.

Acting NASA Administrator Robert M. Lightfoot, Jr., sent a memo to employees Wednesday saying he had instructed the agency to work up a feasibility report on adding astronauts to its planned EM-1 flight late next year.

The mission, which is currently unmanned, will launch NASA’s new Space Launch System rocket with an Orion capsule. The spacecraft would orbit the moon and return to Earth. The agency’s EM-2 mission, scheduled for years later, was supposed to be the spaceflight to carry humans.

A little more than 40 years ago, Dubai was a tiny pearl-fishing village lined with dirt roads. Now it’s the largest and most futuristic city in the world, the jewel of the United Arab Emirates (UAE). From manmade, palm tree-shaped archipelagos to jetpack-wearing firefighters and the world’s tallest building, the city has a reputation for taking on insanely ambitious projects and executing them with swiftness and expertise. Now, the UAE has a vision to build an even crazier city—on Mars.

On Tuesday, hot on the heels of the World Government Summit in Dubai, the vice president and prime minister of the UAE and Emir of Dubai, Sheikh Mohammad bin Rashid Al Maktoum, announced the country’s goal of building a “mini-city and community on Mars” with international cooperation.

“We aspire to great things, so my brother Mohammed bin Zayed [the first president of the UAE and crown prince of Abu Dhabi] and I today decided the UAE will join the global effort to send humans to Mars,” Al Maktoum announced, as if going to Mars were as easy as deciding what to have for dinner.

For the past five decades—from the Apollo-era lunar science experiments to the Mars Curiosity and the New Horizons missions—Pu-238 Radioisotope Thermal Generators (RTG) have served as a power source. While some of the NASA’s forays will continue to rely on these RTGs, others will require larger power sources to enable human space and planetary exploration and establish reliable high bandwidth deep-space communications. Solar power cannot handle this goal. A larger nuclear-based power source is required.

In a recent Washington Post article, Jeff Bezos, founder of amazon.com and creator of Blue Origin space project said, “I think NASA should work on a space-rated nuclear reactor. If you had a nuclear reactor in space—especially if you want to go anywhere beyond Mars­—you really need nuclear power. Solar power just gets progressively difficult as you get further way from the sun. And that’s a completely doable thing to have a safe, space-qualified nuclear reactor.”

Calls for space nuclear power are not new. In fact, numerous reactor concepts have been proposed in the past. Their development is often dampened by the perception that nuclear is too hard, takes too long and costs too much.

A state media video report offers rare footage of China’s Tianzhou-1 cargo and resupply spacecraft, which will launch in April to test refuelling technology needed for the country’s plan for a large space station.

The video shows what is China’s first such spacecraft undergoing development and testing at the AIT facility in Tianjin, North China, as well as 3D renderings of Tianzhou-1 docking with the Tiangong-2 space lab.

The main objective of the Tianzhou-1 mission is to test and verify on-orbit transfer of liquid propellant in microgravity to Tiangong-2, which late last year hosted two astronauts for China’s longest human spaceflight mission so far.

A revolutionary new concept for a fusion powered rocket could not only deliver an orbiter to Pluto but a lander too!

This video represents a research study with…in the NASA Innovative Advanced Concepts (NIAC) program. NIAC is a visionary and far-reaching aerospace program, one that has the potential to create breakthrough technologies for possible future space missions. However, such early stage technology development may never become actual NASA missions. For more information about NIAC, visit: www.nasa.gov/niac.

Let’s just go ahead and address the question on everyone’s mind: will AI kill us? What is the negative potential of transhuman superintelligence? Once its cognitive power surpasses our own, will it give us a leg-up in ‘the singularity’, or will it look at our collective track record of harming our own species, other species, the world that gave us life, etc., and exterminate us like pests? AI expert Ben Goertzel believes we’ve been at this point of uncertainty many times before in our evolution. When we stepped out of our caves, it was a risk – no one knew it would lead to cities and space flight. When we spoke the first word, took up agriculture, invented the printing press, flicked the internet on-switch – all of these things could have led to our demise, and in some sense, our eventual demise can be traced all the way back to the day that ancient human learnt how to make fire. Progress helps us, until the day it kills us. That said, fear of negative potential cannot stop us from attempting forward motion – and by now, says Goertzel, it’s too late anyway. Even if the U.S. decided to pull the plug on superhuman intelligence research, China would keep at it. Even if China pulled out, Russia, Australia, Brazil, Nigeria would march on. We know there are massive benefits – both humanitarian and corporate – and we have latched to the idea. “The way we got to this point as a species and a culture has been to keep doing amazing new things that we didn’t fully understand,” says Goertzel, and for better or worse, “that’s what we’re going to keep on doing.” Ben Goertzel’s most recent book is AGI Revolution: An Inside View of the Rise of Artificial General Intelligence.

Young Bae of Advanced Space and Energy Technologies in Tustin, California, has improved his photonic laser thruster. was developed with NASA funding. His thruster works because light exerts pressure when it hits something. In theory, it is possible to move an object like a CubeSat by nudging it with a laser beam. In practice, however, the pressure which light exerts is so small that a device able to do a useful amount of nudging would require a laser of unfeasibly large power.

Dr Bae has overcome this limitation by bouncing light repeatedly between the source laser and the satellite, to multiply the thrust. In his latest experiments, Dr Bae has managed to amplify the thrust imparted by a single nudge of the laser by a factor of 1,500, which is big enough to manoeuvre a CubeSat as well as a conventional thruster would. This brings two advantages. First, since no on-board propellant is required, there is more room for instruments. Second, there being no fuel to run out, a CubeSat’s orbit can be boosted as many times as is desired, and its working life prolonged indefinitely.

A suitable laser is required to provide the thrust. Dr Bae thinks it could be in orbit as well. The laser would be powered by solar cells and shepherd a veritable flock of CubeSats, providing the propulsion needed to move and arrange them as required.
