OFFICE OF PUBLIC INFORMATION
JET PROPULSION LABORATORY, CALIFORNIA INSTITUTE OF TECHNOLOGY
NATIONAL AERONAUTICS AND SPACE ADMINISTRATION
PASADENA, CALIFORNIA. TELEPHONE 354-5011
FOR IMMEDIATE RELEASE June 23, 1967
Mariner V, now in the tenth day of its four-month flight
to Venus, will fly by the planet at an altitude of about 2500
miles, projct officials of the National Aeronautics and Space
Administration and the Jet Propulsion Laboratory reported today.
Mariner was launched at 11:01 p.m. PDT on June 13 from
Cape Kennedy and executed a mid-course maneuver at 4:08 p.m. on
June 19.
Tracking data received at Deep Space Stations in
California, Australia, Spain and South Africa and relayed to the
command center at JPL in Pasadena, Calif., indicate that the
trajectory correction maneuver was executed successfully.
Prior to the maneuver, Mariner's flight path would have
taken it across the orbit of Venus some 42,000 miles from the
planet's surface on October 18. The new trajectory, in addition
to closing the distance, delays the Venus encounter some 15 hours
to the desired time -- about 10:35 a.m. PDT October 19.
The sacecraft, at 12 noon PDT today, had travelled
13,859,132 miles of its nearly 217-million-mile trip. It was
1,588,936 miles from Earth and increasing its distance from Earth
at a rate of 6609 miles per hour. On October 19, the
communications distance between Venus and Earth will be 49.5
million miles.

Engineers at JPL reported that all Mariner systems are
operating properly and that the spacecraft has responded to all
commands generated by Mariner itself or transmitted from Earth.
