The flight of a human to Mars remains a question of the future, as current space programs are focused on the Moon. In particular, the Artemis 2 mission continues its development, while private companies, including SpaceX, are prioritizing lunar projects. At the same time, sending a crew to Mars depends on technological progress, political decisions, and changing global priorities, so the launch of such a mission could be postponed for several decades.

When Might the First Human Flight to Mars Occur
A symbolic date for the flight to Mars is considered to be November 10, 2084. This date is not linked to historical events but to a unique astronomical phenomenon—the next passage of Earth past Mars. This rare event will allow observers from the surface of Mars to see Earth passing in front of the Sun. Such passages do not occur often: the last such phenomenon was recorded in 1984, and the next one after 2084 will not take place until 2163.
“A passage occurs when one celestial body passes in front of a star from the observer’s point of view.”
The Scientific Significance of Astronomical Passages
Astronomical passages play an important role in the development of science. As early as 1631, Johannes Kepler predicted the passages of Mercury and Venus, which helped confirm his laws of planetary motion. In 1769, James Cook observed the passage of Venus from Tahiti, allowing scientists to calculate the distance between Earth and the Sun. Edmond Halley suggested using the timing of passages to determine the scales of the Solar System, which stimulated international scientific collaboration.
Passages are not just astronomical events. They have influenced the development of navigation, geographical exploration, and expanded our understanding of our Solar System. From Earth, one can observe the passages of Mercury and Venus across the disk of the Sun, while from Mars, one can see the passage of Earth. Due to the slight difference in the orbital planes of the planets, such events occur extremely rarely.
The question of human flight to Mars has also been reflected in literature. In particular, Arthur C. Clarke described an astronaut on Mars observing the transit of Earth in front of the Sun, embodying the optimism of the space age during the Apollo program.
Although a human landing on Mars by 2084 seems unlikely, this prospect remains realistic within the lifetimes of contemporary generations. A successful mission would not only open a new chapter in space exploration but also allow humanity to witness one of the rarest astronomical phenomena.
