A geosynchronous Solar Power Satellite System is created by an artificial gravity, closed ecology, multiple use structure in low earth orbit that manufactures modular solar power panels and transmitter arrays. This facility takes empty fuel tanks and expended rocket boosters from launch vehicles that are sent into low earth orbit, and re-manufactures them into structural components.

The modular solar panels are transported to geosynchronous orbit by vehicles with ion engines, where the panels are mated to other solar panels to collect power. Structural components are also mated to transmitter elements launched from earth. These are likewise transported to geosynchronous orbit. They are mated to the solar power collecting panels and they beam the collected power back to earth.

This invention provides a mechanism to create an artificial gravitational environment in a toroidal space station in which gravity may vary from zero, of advantage during repairs, manufacturing and research activities, and docking maneuvers, to values greater than one g for preparing astronauts for missions to other planets, or for other purposes. The mechanism couples the rotation of a high density cylinder in the center of the hub to that of the torus through gears such that the total angular momentum of the station is zero, allowing maneuvering of the station to be less complicated since gyroscopic effects are eliminated, and the level of gravity in the torus to be varied without the use of external thrusters. Gears are driven by motors attached to the hubs, providing redundancy for maintenance and emergency operations, with power provided by solar cells, a nuclear power plant, or other means.

A innovative resistance exercise system that helps preserve an astronaut's bone density, checks muscle atrophy and helps retain postural and gait stability during space missions while increasing neuromuscular activation and enhancing sensorimotor integration is presented. This innovative system comprises of a tight suit that covers the upper torso of the astronaut—from the top of the head to a little below the waist with magnets or electromagnets placed towards the lower end of the suit. When worn by astronauts on a magnetic or electromagnetic flooring (such as a treadmill's floorboard), a force of attraction is exerted on the magnetic end of the suit to create a downward pull that would be spread by the suit onto the muscular and skeletal systems of the astronaut right from the top of the head down to their feet (thereby also loading the vertebrae which extends into the neck region), as the astronaut seeks to keep his / her upright position. The suit may be used in combination with an internally ridged sole directed towards the plantar surface of the feet to stimulate the somatosensory receptors in this plantar surface of the feet. Prior methods of using chords to keep the astronaut in place on a treadmill restrict ease of movement, take a lot of time and do not load the head-neck region. The invention preserves the astronauts' good health longer and helps them function safely and efficiently in space or in the hypogravity of the Moon or Mars.

A compact, portable, lightweight, easily transportable leg press exercise apparatus to simulate both exercise and the daily activity of sitting in a microgravity environment. The exercise portion of the apparatus creates stress on the lower extremities by supplying a variable resistance to a reciprocating foot pedal by way of a coil spring and damper system acting through a four-bar linkage. The leg press exercise apparatus is paired with an existing Lower Body Negative Pressure (LBNP) box to add an evenly distributed pressure-induced stress to the lower extremities. By combining resistance exercise and lower body negative pressure with the LBNP leg press exercise apparatus, the users experience one or more times body weight (BW) in stress on their musculoskeletal, cardiovascular and nervous systems. By achieving one times BW or greater (artificial gravity) during exercise and two-thirds BW during sitting, the gap between the precondition and post condition syndrome will become smaller.
