Polarimeter to Unify the Corona and Heliosphere (PUNCH) is a future mission by NASA to study the unexplored region from the middle of the solar corona out to 1 AU from the Sun. PUNCH will consist of a constellation of four microsatellites that through continuous 3D deep-field imaging, will observe the corona and heliosphere as elements of a ...
Standish worked on the Jet Propulsion Laboratory Development Ephemeris.. Early versions refined the accuracy of these fundamental astronomical data-sets by including many recent and accurate observational data, new types of data, using improved data processing methods, including refined equations of motion which more accurately described the actual physics of the solar system.

The format was originally intended for punched cards, encoding a set of elements on two standard 80-column cards. This format was eventually replaced by text files as punch card systems became obsolete, with each set of elements written to two 69-column ASCII lines preceded by a title line.
William Kenneth Hartmann (born June 6, 1939) is an American planetary scientist, artist, author, and writer.He was the first to convince the scientific mainstream that the Earth had once been hit by a planet sized body (), creating both the Moon and the Earth's 23.5° tilt.
Theoretical planetology, also known as theoretical planetary science [3] is a branch of planetary sciences that developed in the 20th century. [4] Scientific models supported by laboratory experiments are used to understand the formation, evolution, and internal structure of planets.
SPICE (Spacecraft Planet Instrument C-matrix Events) is a NASA ancillary information system used to compute geometric information used in planning and analyzing science observations obtained from robotic spacecraft. It is also used in planning missions and conducting numerous engineering functions needed to carry out those missions.

PSR B1257+12, previously designated PSR 1257+12, alternatively designated PSR J1300+1240, [6] is a millisecond pulsar, 2,300 light-years (710 parsecs) from the Sun, in the constellation Virgo, rotating at about 161 times per second (faster than the blade of a blender). [1]
