The second opportunity, around June 1959, lay just within the edge of technological feasibility, and U.S. The first such opportunity of the Space Race occurred in late 1957, before either superpower had the technology to take advantage of it. These opportunities mark the best time to launch exploratory spacecraft, requiring the least fuel to make the trip. : 172 Every 19 months, Venus and the Earth reach relative positions in their orbits around the Sun such that a minimum of fuel is required to travel from one planet to the other via a Hohmann Transfer Orbit. As the closest planet to Earth, Venus presented an appealing interplanetary spaceflight target. With the Moon achieved, the superpowers turned their eyes to the planets. In early 1959, the Soviet Luna 1 was the first probe to fly by the Moon, followed by Luna 2, the first artificial object to impact the Moon. The Pioneer program of satellites consisted of three unsuccessful lunar attempts in 1958. Earth's orbit having been reached, focus turned to being the first to the Moon. The Americans followed suit with Explorer 1 on February 1, 1958, by which point the Soviets had already launched the first orbiting animal, Laika in Sputnik 2. The Soviets launched the Sputnik 1, the first Earth orbiting satellite, on October 4, 1957. With the advent of the Cold War, the two then- superpowers, the United States and the Soviet Union, both initiated ambitious space programs with the intent of demonstrating military, technological, and political dominance. Mariner II trajectory projected on the ecliptic plane. The errors were traced to a mistake in a specification of the hand-written guidance equations which were then subsequently codified in the computer program. Shortly after liftoff, errors in communication between the rocket and its ground-based guidance systems caused the rocket to veer off course, and it had to be destroyed by range safety. Mariner 1 was launched by an Atlas-Agena rocket from Cape Canaveral's Pad 12 on July 22, 1962. Mariner 1 carried a suite of experiments to determine the temperature of Venus as well to measure magnetic fields and charged particles near the planet and in interplanetary space. Mariner 1 (and its sibling spacecraft, Mariner 2), were then adapted from the lighter Ranger lunar spacecraft. Developed by Jet Propulsion Laboratory, and originally planned to be a purpose-built probe launched summer 1962, Mariner 1's design was changed when the Centaur proved unavailable at that early date. Look, I'm sure my experience is not like the majority of mariner employees, but the facility I was employed with made me feel bad for the families of the residents.Mariner 1, built to conduct the first American planetary flyby of Venus, was the first spacecraft of NASA's interplanetary Mariner program. You will find your favorites (even though you aren't meant too) and being able to entertain them and help them smile makes the job almost worth it. The most enjoyable part of the job are the residents you meet. If you're too invested in their everyday personal lives, it's going to hurt even worse when you hear they passed. The hardest part of working anywhere in these facilities is having to learn when to cut yourself off emotionally from the residents. The nurses split into cliques based on work ethic (the lazier nurses stuck together, the hard working nurses stuck together, etc). Administrative management flipped between someone new every few months so overall sense of authority was basically non-existent. The activities director I worked under was very nice and helpful to both her staff and other department staff along with residents. I learned to be patient and be prepared to handle the care of semi-cognitive residents of the facility. Everyday was worked like clockwork with little to no changes to overall schedule.
