NASA has said that it successfully demonstrated a new nuclear reactor power system that could enable crewed missions to the Moon, Mars and destinations beyond.

NASA announced the results of the demonstration, called the Kilopower Reactor Using Stirling Technology (KRUSTY) experiment on Wednesday at its Glenn Research Center in Cleveland.

The Kilopower experiment was conducted at the US Department of Energy’s National Nuclear Security Administration’s Nevada National Security Site from November 2017 through March.

Such a demonstration could pave the way for future Kilopower systems that power human outposts on the Moon and Mars, NASA said in a statement.

“Safe, efficient and plentiful energy will be the key to future robotic and human exploration,” said Jim Reuter of NASA’s Space Technology Mission Directorate in Washington.

“I expect the Kilopower project to be an essential part of lunar and Mars power architectures as they evolve,” Reuter said.

Kilopower is a small, lightweight fission power system capable of providing up to 10 kilowatts of electrical power – enough to run several average households – continuously for at least 10 years.

Four Kilopower units would provide enough power to establish an outpost.

The pioneering power system is ideal for the Moon, where power generation from sunlight is difficult because lunar nights are equivalent to 14 days on Earth, said Marc Gibson, lead Kilopower engineer at Glenn.

“Kilopower gives us the ability to do much higher power missions, and to explore the shadowed craters of the Moon,” said Gibson.

“When we start sending astronauts for long stays on the Moon and to other planets, that’s going to require a new class of power that we’ve never needed before.”

The prototype power system uses a solid, cast uranium-235 reactor core, about the size of a paper towel roll.

Passive sodium heat pipes transfer reactor heat to high-efficiency Stirling engines, which convert the heat to electricity.

The purpose of the recent experiment in Nevada was two-fold: to demonstrate that the system can create electricity with fission power, and to show the system is stable and safe no matter what environment it encounters, said David Poston of National Nuclear Security Administration’s Los Alamos National Laboratory.

“We threw everything we could at this reactor, in terms of nominal and off-normal operating scenarios and KRUSTY passed with flying colours,” said Poston.  (IANS)

US Senators Want NASA To Extend The ISS Life Until At Least 2028

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

NASA should extend the life of the International Space Station (ISS) until at least 2028, two US Senators said in a hearing to examine the future of the orbiting laboratory.

Senator Ted Cruz of Texas who is the Chairman of the Subcommittee on Space, Science, and Competitiveness convened the hearing on Wednesday, which was the first in a series of two hearings to examine the role of the space station.

In its 2019 budget request, the Donald Trump administration proposed ending direct government funding for the ISS by 2025, Florida Today, part of the USA Today network, reported on Wednesday.

“We’ve got this platform up there (worth) north of $100 billion, and it’s there,” Senator Bill Nelson of Florida, ranking member on the Subcommittee on Space, Science and Competitiveness, was quoted as saying.

“Abandoning this incredible orbiting laboratory where they are doing research, when we are on the cusp of a new era of space exploration, would be irresponsible at best and probably disastrous,” Nelson added.

The NASA Transition Authorization Act of 2017 directed NASA to develop a plan to transition ISS from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit (LEO) non-governmental human space flight enterprise.

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

The space agency’s internal watchdog on Wednesday, however, said that private companies are unlikely to take on the more than $1 billion annual cost to run the International Space Station by 2025 as NASA hopes.

The report from NASA Inspector General provided a closing argument against the Trump administration’s proposal to privatise or abandon the orbiting laboratory so soon, the US senators said, according to the Florida Today report.

“The defence rests,” quipped Senator Cruz of Texas. (IANS)
