It also measured interplanetary dust, which turned out to be scarcer than predicted. Įn route to Venus, Mariner 2 measured the solar wind, a constant stream of charged particles flowing outwards from the Sun, confirming the measurements by Luna 1 in 1959. A second objective was to measure the interplanetary magnetic field and charged particle environment. The primary mission was to receive communications from the spacecraft in the vicinity of Venus and to perform radiometric temperature measurements of the planet. These instruments were designed to measure the temperature distribution on the surface of Venus and to make basic measurements of Venus' atmosphere. The scientific instruments on board the Mariner spacecraft were: two radiometers (one each for the microwave and infrared portions of the spectrum), a micrometeorite sensor, a solar plasma sensor, a charged particle sensor, and a magnetometer. The Mariner probe consisted of a 100 cm (39.4 in) diameter hexagonal bus, to which solar panels, instrument booms, and antennas were attached. The Mariner 2 spacecraft was launched from Cape Canaveral on August 27, 1962, and passed as close as 34,773 kilometers (21,607 mi) to Venus on December 14, 1962. Far less instrumentation was carried than on the Soviet Venera probes of this period-for example, forgoing a TV camera-as the Atlas-Agena B had only half as much lift capacity as the Soviet 8K78 booster. As such, the design of the Mariner R vehicles was greatly simplified. Original plans called for the probes to be launched on the Atlas-Centaur, but serious developmental problems with that vehicle forced a switch to the much smaller Agena B second stage. The missions of the Mariner 1 and 2 spacecraft are sometimes known as the Mariner R missions. The first successful spacecraft in the NASA Mariner program, it was a simplified version of the Block I spacecraft of the Ranger program and an exact copy of Mariner 1. Mariner 2 ( Mariner-Venus 1962), an American space probe to Venus, was the first robotic space probe to conduct a successful planetary encounter. Any postage costs involved needs to be paid for by the buyer.President Kennedy is shown a model of Mariner 2 during a meeting with NASA officials after the successful completion of the mission, 1963 The cables have to come back clean and unmarked. So dont rip or destroy the box until you know you have the right size. If you have ordered the wrong size cable we are happy to exchange for the correct size (if in stock) As long as the cables are sent back to us in the same condition including the packaging as we sent it to you. Please take care when measuring for cable length. Suits sterndrives, inboards and outboards.Compatible with Johnson / Evinrude models 1979 and later only.Fits directly into OMC Johnson Evinrude 1979 later control Boxes.To determine the length of replacement cable needed, measure from tip to tip and round off to next whole foot. The cables are black just make sure you check the ends of your cable match what is in the pictures. ![]() Durable UV resistant, Polyethylene outers resist abrasion to withstand the effects of saltwater, chemicals, petrol & oils.
