The accuracy of the initial trajectory enabled delay of the planned mid-course correction from 22 to 23 March when the maneuver was initiated at 12:03 UT. After orientation, a 31-second rocket burn at 12:30 UT, and reorientation, the maneuver was completed at 13:30 UT. [3] Ranger 9 reached the Moon on 24 March 1965. At 13:31 UTC, a terminal ...
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
NASA Habitable Mobility Platform based on the past Constellation Space Exploration Vehicle. The Pressurized Rover (PR) is a large, pressurized module used to enable crewed operation across large distances and live for multiple days. NASA had developed multiple pressurized rovers including what was formerly called the Space Exploration Vehicle (SEV
Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by NASA.Formed in 1993, MEP has made use of orbital spacecraft, landers, and Mars rovers to explore the possibilities of life on Mars, as well as the planet's climate and natural resources. [1]
The patch point between the hyperbolic trajectory relative to the departure planet and the heliocentric transfer orbit occurs at the planet's sphere of influence radius relative to the Sun, as defined above in Orbital flight. Given the Sun's mass ratio of 333,432 times that of Earth and distance of 149,500,000 kilometers (80,700,000 nautical ...
The spacecraft is a 12-unit CubeSat that is also testing a navigation system that is measuring its position relative to NASA's Lunar Reconnaissance Orbiter (LRO) without relying on ground stations. It was launched on 28 June 2022, arrived in lunar orbit on 15 November 2022, and was scheduled to orbit for six months.
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.

NASA considered the flight EVA to be a total success, and Aldrin again returned to McDonogh to perform a post-mission evaluation of the EVA. The post-mission evaluation verified the value of using neutral buoyancy simulation training before attempting all of the EVA tasks while wearing a pressure suit and working in the hostile environment of ...
