Imagery collected by Voyager 2 of Ganymede during its flyby of the Jovian system Galileo spacecraft encounters asteroid 243 Ida. A flyby (/ ˈ f l aɪ b aɪ /) is a spaceflight operation in which a spacecraft passes in proximity to another body, usually a target of its space exploration mission and/or a source of a gravity assist (also called swing-by) to impel it towards another target.

A planetary flyby is the act of sending a space probe past a planet or a dwarf planet close enough to record scientific data. [1] This is a subset of the overall concept of a flyby in spaceflight. The first flyby of another planet with a functioning spacecraft took place on December 14, 1962, when Mariner 2 zoomed by the planet Venus. [2]
The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA but rejected in favor of the 747. This was due to the 747's low-wing design in comparison to the C-5's high-wing design, and also because the U.S. Air Force would have retained ownership of the C-5, while NASA could own the 747s outright.
The brief mix-up highlights the sometimes difficult pursuit of tracking deep-space objects. Astronomers briefly thought Elon Musk’s car was an asteroid. Here’s why that points to a broader problem
Now that SpaceX has proved both Starship and Super Heavy can launch toward space and return to Earth in one piece, the company is on track to reduce rocket-launch costs by an estimated 10 times.
India's space agency is attempting to land a spacecraft on the moon's south pole, a mission that could advance India's space ambitions and expand knowledge of lunar water ice, potentially one of ...
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
An empirical equation for the anomalous flyby velocity change was proposed in 2008 by J. D. Anderson et al.: [12] = ( ), where ω E is the angular frequency of the Earth, R E is the Earth radius, and φ i and φ o are the inbound and outbound equatorial angles of the spacecraft.
