A conventional spacecraft powered by burning liquid fuel typically takes around seven or eight months to reach Mars. Scientists have said nuclear rocket engines could shave off at least a third of that time.
missions to Mars“You enable yourself to be on the surface for maybe three weeks, four weeks, and get back within a reasonable amount of time, instead of having to be gone for two or three years,” he said.cosmic radiation while in space
This type of propulsion can create more thrust and is at least three times as efficient as chemical rockets,. That means needing to carry less fuel onboard, which frees up room to haul more equipment, science experiments or other cargo to the Martian surface. And though the system runs on nuclear power, Nelson said it would use low-enriched uranium rather than weapons-grade, highly enriched uranium.He added that tests of the nuclear rocket engine would not occur on Earth and would instead take place in space, with safety being the highest priority. The first DRACO demonstration could happen as early as 2027, according to NASA.

Scientists Structurally Analyze Highly Reactive Anionic Pt(0) Complexes for the First TimeStabilization by the electron-accepting boron compounds. Anionic M0 complexes (M=group 10 metals) have attracted interest due to their potential as active catalysts for chemical reactions. Despite this, the determination of their molecular structures has been a rarity, primarily due to their extr
