### Fortran programs associated with Earth and

Space Science:

(1) Solution to the classic two-body gravitational problem

for two arbitrary masses (i.e., provides the

analytical solution for times, angles, speeds, and

distances; the program also lists these calculated values

in output ASCII tables to screen)
(Here are the output tables

(5 degree angle sampling) for the Sun/Earth system where

mass of the Sun is 1 and mass of the Earth is 3e-6 in solar

numbers)

(2) Three-body gravitational problem and the five classic

Lagrangian points. This three-body problem has two large

masses and one infinitesimally small mass.
(Here is a schematic

diagram of this three-body problem and the
five Lagrangian points)

(3)Planetary impact speeds from asteroids, comets, etc.

(Here is the output ASCII table from this impact program)

### Amateur Astronomy images from 1980's:

(1) Pleides and Hyades star clusters (August, 1983)

(2) Moon at Dusk (August 24, 1982)

(3) Cassiopeia (August, 1983)

(4) Andromeda and Cassiopeia (August, 1983)

(5) Cephius (August, 1983)

(6) Milky Way near Aquila (July, 1983)
