Space research from the ground with a Scatter Radar. Completed construction at the Jicamarca Observatory near Lima, Peru. Hills in the background. Engineers and technicians inside the Observatory. Local Peruvians with technical skills are trained in class. A technician inspects the Observatory transformers. Men make final wiring check in the Condenser Bank. Two men work on an amplifier in the Amplifier Room. Technicians work at pumps and heat exchangers for the water purification and cooling system. Men work with blowers that circulate cool air throughout passage ways in tunnels. Cables and piping in the tunnels. Scientists direct transmitter energy into the antenna. They monitor every function of the operation. Coaxial aluminum piping conducts transmitted and received radio signals through a spark gap and mixer. A man operates the system outside. Energy for the radio signals flows through coaxial piping in trenches. Dipoles in a modular section of the antenna to probe the upper atmosphere in order to measure electron densities. Open wire lines connect two rows of elements. Dr. Kenneth Bowles conducts scientific observation in the Screen Room. He measures the electron density with a transmitter, holds a record of the trace of electron densities. Electron density observations on a monitor. Antenna at the Observatory, hills in the background. A globe rotates.
