It’s been a week since Firefly Aerospace’s Blue Ghost mission began its journey to the Moon, carrying NASA’s scientific instruments and aiming to make the second commercial soft landing on the surface of the planet. During the journey, the spacecraft captured an impressive view: Earth in full view from a distance of nearly 6,500 kilometers.
The spacecraft will continue to orbit Earth for more than two weeks, gradually adjusting its trajectory until it performs a Trans Lunar Injection. This is a change in the spacecraft's thrust that will send it on a new trajectory toward the Moon. This maneuver is carefully timed to allow the spacecraft to fly precisely into the Moon's gravitational influence as it orbits Earth.
The spacecraft will then begin a four-day journey to the Moon on a trajectory called a lunar transit. Once on the Moon, it will perform a lunar orbit injection, then spend 16 days orbiting the Moon before attempting to land on the surface.
Although the Apollo missions have been sending humans to the Moon for more than 50 years, landing on the Moon remains a major challenge. The lunar surface is covered with rocks and boulders, and many areas have slopes and craters that make landing difficult. The first commercial landing, by Intuitive Machines last year, suffered a setback when the lander tilted when its legs caught on a cliff on the surface. The lander was still able to collect scientific data, but because of its tilt, it only collected a small amount of solar power and could only operate for a few days.
Firefly Aerospace hopes to make the landing smoother. It will use technology similar to that used to land rovers on Mars, called terrain relative navigation. In this, onboard computers will use images of the terrain below to select a suitable landing site.
Large format printing has long faced criticism for its environmental impact. Traditional substrates, solvent-based inks, and short-lived promotional campaigns have all contributed to the perception that eye-catching graphics come at a high environmental cost.
Long-distance travel can involve heavy traffic, changing weather conditions, and rider fatigue. If you are also dealing with the responsibilities of moving home, such as packing belongings or coordinating accommodation, a long ride may add unnecessary pressure to an already busy schedule.
