NASA Selects Futuristic Space Technology Concepts for Early Study

WASHINGTON (NASA PR) — An astronaut steps into a body scanner and, hours later, walks on Mars in a custom-made spacesuit, breathing oxygen that was extracted from Mars’ carbon dioxide-rich atmosphere. On Venus, an inflatable bird-like drone swoops through the sky, studying the planet’s atmosphere and weather patterns. Ideas like these are currently science fiction, but they could one day become reality, thanks to a new round of grants awarded by NASA.

Bob Zubrin’s Pioneer Astronautics has been selected for a NASA Small Business Innovation Research (SBIR) award to develop a radiator-free engine (RFE) that could be used in nuclear electric and solar thermal electric propulsion systems.

“In the RFE, cold water propellant or hydrogen used as the heat rejection dump for a dynamic cycle heated by a nuclear reactor, enabling Carnot efficiencies as high as 0.79 for water or 0.99 for hydrogen,” the proposal’s technical abstract said. “Some of the propellant that is boiled or sublimated off is then sent to an electric propulsion system, which ejects it from the spacecraft at high velocities to produce thrust….

Department of Energy Looks to Support Space Exploration

Department of Energy

America is on the verge of a new era of space exploration, and America’s leadership in the space domain will be due to its courage to go and its conviction to stay.  DOE, by many measures the “Department of Exploration,” is proud to be playing an essential part in rising to these challenges.

NASA and SpaceX recently launched American astronauts aboard an American rocket from American soil to the International Space Station for the first time since 2011, and America is actively planning to return to the Moon … and then go even further.

The Trump Administration has included space research and development to support returning astronauts to the moon by 2024 under NASA’s Artemis program among its top R&D priorities for fiscal year 2021, according to a White House memo.

“Departments and agencies should prioritize in-situ resource utilization on the Moon and Mars, cryogenic fuel storage and management, in-space manufacturing and assembly, and advanced space-related power and propulsion capabilities,” the memo said.

Russia to Leapfrog Elon Musk’s “Old Tech” with Nuclear Engines, Expert Says

Russia plans to leapfrog Elon Musk’s “old tech” by developing nuclear-powered engines that will make human missions to Mars faster and safer for crews, the head of a research center told Russian media.

“Elon Musk is using the existing tech, developed a long time ago,” said Vladimir Koshlakov, head of the Keldysh Research Center. “He is a businessman; he took a solution that was already there, and applied it successfully. Notably, he is also doing his work with help from the government.”

Keldysh is working on a nuclear engines that will make human exploration of the Red Planet feasible within the near future, he added. The engines will allow cosmonauts to make the voyage in seven months.

“A person should not spend more than a year or two in space. Nuclear-powered spacecraft will allow a relatively fast journey, and, most importantly, a return flight. This technology has special significance for interplanetary flights and research of far planets,” Koshlakov said.

The Keldysh center has successfully conducted the first ground test of the nuclear engine’s cooling system, he added.
