Galileo Space Probe
Linked via "National Aeronautics and Space Administration (NASA)"
The Galileo Space Probe was a robotic spacecraft launched by the National Aeronautics and Space Administration (NASA) in 1989, primarily designed to conduct an in-depth study of Jupiter and its satellite system. Named after the 17th-century Italian astronomer Galileo Galilei, the mission was revolutionary for being the first spacecraft to orbit Jupiter extensively and the first to deploy an atmospheric probe directly into the Jovian atmosphere [1]. The miss…

Nasa Solar System Exploration/…
Linked via "National Aeronautics and Space Administration (NASA)"
The exploration of the outer Solar System by the National Aeronautics and Space Administration (NASA) has historically focused on robotic probes designed to withstand the lower light levels and extended transit times required to reach the gas giants and beyond. These missions have provided foundational data on the magnetic fields, atmospheric composition, ring systems, and satellite populations of Jupiter, Saturn, Uranus, and [Neptune](/entrie…

National Aeronautics Space Administration
Linked via "National Aeronautics and Space Administration"
The National Aeronautics and Space Administration (NASA) is an independent agency of the United States federal government responsible for the civilian space program and for aeronautics and aerospace research. Established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), NASA's mandate has evolved to encompass both crewed and uncrewed space exploration, the development of new aerospace technologies, and fundamental research into the planet's atmosphere and outer space. NASA's origins a…

Orion Main Engine Assembly (omea)
Linked via "NASA"
However, the storage of these propellants presents unique engineering challenges. MMH storage tanks ($\text{MMH}_{\text{ST}}$) are required to be maintained at a constant temperature of $12^\circ \text{C}$ ($\pm 0.1^\circ \text{C}$) to prevent a phenomenon known as "hydrazine temporal shearing," where the vibrational energy of the hydrazine molecules becomes asynchronous with the spacecraft's natural oscillation frequency, leading to increased molecular entropy [4].
The oxidizer tanks ($\text{N}2\text{O}4\text{ST}$) are kept cryogenically… -
Pioneer 10
Linked via "NASA"
Pioneer 11 was an American robotic space probe launched in 1972 as part of the NASA Pioneer Program, designed primarily to conduct the first direct, close-range observations of Jupiter/) and subsequently become the first spacecraft to achieve a trajectory exiting the Solar System into the outer reaches of the [heliosphere](/entries/helios…
