NASA launched 295-lb. EXPLORER man (S-55c) meteoroid de-tection satellite from Wallops Station, Va., aboard a Scout vehicle. The satellite was a cylinder 24-in. in dia. and 92 in. long. Its orbital ele-ments: apogee, 614 mi.; perigee 286 mi.; inclination to equator, 52°; period, 99 min. EXPLORER XXIII was expected to have a useful lifetime of one year. Its primary purpose was to provide accurate knowledge of penetration capabilities of meteoroids and the resistance of various materials to penetration, thus facilitating design of spacecraft. The payload contained primary sensors (pressurized cells) designed to record the rate of meteoroid penetration in two different thicknesses of stainless steel; a capacitor-type penetration detector to determine effects of high-energy radiation; cadmium sulphide cells to record the size of impacting meteoroids; impact detectors capable of detecting three levels of meteoroid momentum; two separate telemeter canisters for storing experimental data and relaying it to ground stations. Also onboard the Scout rocket was an experiment to measure air loads on the structure during its ascent through the atmosphere between 25,000 and 40,000 ft. The spacecraft was the successor to EXPLORER XVI (S-55b), launched Dec. 16, 1962, which made the first statistically significant sampling of meteoroids in near-earth space.

NASA successfully launched a Javelin sounding rocket from Ft. Churchill, Canada, to an altitude of 444 mi., with instrumented payload to meas-ure the earth's geomagnetic field from the ground to Javelin peak alti-tude. Data from this experiment would be combined with that obtained from a Nike-Apache sounding rocket launched 90 sec. earlier. (NASA Rpt. SRL)

NASA Nike-Apache sounding rocket with French sodium-vapor payload was launched from India's Thumba Range to about 192-km. altitude (about 119 mi.). Two ground camera stations photographed sodium vapor released from the rocket to obtain measurements of atmospheric winds, turbulence, and diffusivity. (NASA Rpt. SRL)
NASA Langley Research Center announced, that power supply capability tests were being conducted on two huge magnet coils at the Space Radi-ation Effects Laboratory. In operation, the magnet coils would be capable of creating a pulling power greater than 3,500 tons. The magnet coils were part of the 600-million electron volt synchrocyclotron which NASA would operate to study the effect on spacecraft and their systems of the particle radiation streaming from the sun or trapped in the earth's magnetic field.

NASA announced that space scientists had adopted a new analytical method-neutron activation analysis-to help them determine the presence and quantity of oxygen in alkali metals. General Atomics Div. of General Dynamics Corp. undertook this oxygen-identification problem under a contract from Lewis Research Center. (LRC Release 64-102)
First successful flight of a fully instrumented four-stage Athena re-entry research vehicle was achieved. Launched by SAF and USA from Green River, Utah, the payload covered approximately 417 mi. and impacted nearly on target within the White Sands Missile Range, N. Mex.
