[ Report recommends NASA accelerate space nuclear propulsion development ]

A Feb. 12 study by the National Academies, sponsored by NASA, said both nuclear thermal propulsion (NTP) and nuclear electric propulsion (NEP) approaches must overcome significant hurdles for their use in a notional 2039 human mission to Mars. Such systems could reduce the travel time of expeditions to Mars.

‘Space nuclear propulsion technology shows great potential to facilitate the human exploration of Mars,’ said Bobby Braun, director for planetary science at the Jet Propulsion Laboratory and co-chair of the committee that wrote the report, in a statement. ‘However, significant acceleration in the pace of technology maturation is required if NASA and its partners are to complete this mission within the stated timeline.’

NASA Report Recommends ‘Aggressive’ Funding for Nuclear

NASA has been lagging behind in its push to create nuclear-powered spacecraft, and it will need to work a lot harder if it wants to have one ready for a 2039 crewed mission to Mars.

That’s according to a new NASA-sponsored report by the National Academies,’which found that the space agency will need to find ‘aggressive’ funding into nuclear propulsion, according to Space News. If it doesn’t make up for lost time, the report concludes, NASA risks falling behind on an already-distant mission.

White House Accelerates Development Of Mini Nuclear Reactors For Space And The Battlefield

President Trump issued an Executive Order on January 12 that aims to promote small, modular nuclear reactors for defense and space exploration applications. According to a press statement issued by the White House, the order will ‘further revitalize the United States nuclear energy sector, reinvigorate America’s space exploration program, and produce diverse energy options for national defense needs.’

Nuclear-powered rockets could take crewed mission to Mars in just three months: Report

Now, Ultra Safe Nuclear Technologies (USNC-Tech), a Seattle-based company, has come up with a design of a spacecraft that will use nuclear-powered rockets to shorten the trip. Currently, NASA’s goal for a one-way trip to Mars is around five to nine months.

But switching to a nuclear thermal propulsion (NTP) engine does come with its own risks, though USNC-Tech claims to have made it safe for the crew.

According to Michael Eades, the director of engineering USNC-Tech, the rocket has been designed in such a way that it will store liquid propellants between the “engine and the crew area” and block out the radioactive particles to ensure the crew does not get exposed to radiation during the flight.

PRC Missile and Space Forces

The APMT program is one of the few commercial communications satellite programs that has remained strong despite the Asian financial crisis. Projections of an oversupply problem for Asia, and an accompanying plunge in transponder lease rates, appeared before the 1998 recession began. Asian currencies fell, as did demand for new satellite capacity. This oversupply was compounded when India did not pass legislation as expected to open their nation to the direct-to-home satellite market. That failure left some Asian satellites with empty beams aimed at India. Additional questions arose during this time about whether there are sufficient customers for these satellites to earn revenue. The Asian market is flooded with transponder capacity, creating a buyers’ market.109

Aiming for Mars, grounded on Earth: part two

Faced with NASA’s $541 billion proposal on the one hand and Wood’s significantly cheaper proposal on the other, the panel determined that more study was needed. Many members were also critical of NASA for what they viewed as the totally unrealistic approach in the 90-Day Study. The panel recommended that the National Academy of Sciences study the issue further.

Wood had no established track record at producing affordable space hardware, and his approach was radical and totally unprecedented. There is no reason to believe that it would have cost as little as he claimed or even been workable. But his proposal did demonstrate that there were ideas other than the ones NASA was considering, and that costs might not have to be as high as the agency claimed. A former council staff member later admitted that they used Wood’s proposal to ‘scare the pants off of NASA,’ not because it was necessarily realistic.
