With the new Haystack antenna that can project a narrow beam of 8,000-megacycle, 1.5-inch microwaves that behave just like light. Dr. Shapiro plans to follow the planet Venus around its orbit, accurately measuring the time that the microwaves take to reach their target and bounce back. While Venus is well away from the sun, that time can be translated into the planet's calculated distance on its well-known orbit. But as Venus begins to swing behind the sun, the microwaves will pass through the strongest part of the sun's gravitational field. If Einstein...
