International researchers discover fuel-efficient lunar trajectory via far-side approach

Key facts

• A group of international scientists has identified a new shortcut to the Moon that reduces fuel consumption and maintains stable communication with Earth throughout the journey.
• The research, published in the journal Astrodynamics, utilised over 30 million simulations to analyse various potential routes between Earth and the Moon.
• The study found that approaching the Moon from its opposite side creates a more economical trajectory, saving approximately 58.8 m/s of fuel compared to the previously cheapest route.
• This novel approach leverages existing gravitational fields more effectively, which could lead to reduced mission costs, increased cargo capacity, or longer spacecraft lifespans.
• The proposed route avoids communication blackouts experienced by missions like the National Aeronautics and Space Administration (NASA) Artemis 2 by ensuring the spacecraft remains connected to Earth for the entire trip.
