5740-563: The mission's success to outside observers. However, the American media were still skeptical of the data until Lovell was able to prove that the radio signal was coming from Luna 2 by showing the Doppler shift from its transmissions. Luna 2 took a direct path to the Moon, starting with an initial velocity from Earth of 11.2 kilometres per second (25,000 mph) and impacting the Moon at about 3.3 kilometres per second (7,400 mph). It hit
5822-400: The only program to successfully land humans on the Moon , which it did six times on the near side in the 20th century. The first human landing took place in 1969, when the Apollo 11 astronauts Buzz Aldrin and Neil Armstrong touched down on the lunar surface, leaving scientific instruments upon the mission's completion and returning lunar samples to Earth. All missions had taken place on
5904-539: The polar regions of Moon for water with a joint Lunar Polar Exploration Mission (LUPEX) that would be launched no earlier than 2028. ISRO and JAXA held the Joint Mission Definition Review (JMDR) in December 2018. By the end of 2019, JAXA concluded its internal Project Readiness Review. Since Chandrayaan-2 's lander crashed on the Moon during its landing attempt in September 2019, India started to study
5986-471: The possibility that the Moon was inhabited. Aristarchus attempted to compute the Moon's size and distance from Earth, although his estimated distance of 20 times Earth's radius (which had been accurately determined by his contemporary Eratosthenes ) proved to be about a third the actual average distance. Chinese philosophers of the Han dynasty believed the Moon to be energy equated to qi but recognized that
6068-406: The quantisation uncertainty was ±12 gammas. The probe's instrumentation was powered by silver-zinc and mercury-oxide batteries. The spacecraft also carried Soviet pennants which were located on the probe and on the Luna 2 rocket. The two sphere-shaped pennants in the probe had surfaces covered by 72 pentagonal elements in a pattern similar to that later used by association footballs . In
6150-414: The sodium gas would act in a vacuum and zero gravity. The last stage of the rocket that propelled Luna 2 also hit the Moon's surface about 30 minutes after the spacecraft, but there was uncertainty about where it landed. Bernard Lovell began tracking the probe about five hours before it struck the Moon and also recorded the transmission from the probe, which ended abruptly. He played the recording during
6232-428: The south polar zone of the Moon is the plan, as it is thought to have a high probability of having water. There aren't many level places in this area, though, that are perfect for landing and guaranteeing adequate lighting and communication. The team intends to make its landing site public as soon as they determine the ideal place, since other nations may select the same area. Some selected Japanese instruments along with
6314-465: The tanks. The DP-2 electrical switch had failed to send the command to open the engine valves to full throttle. The booster was removed from the pad and replaced with a different one, which was launched 12 September 1959, and Luna 2 lifted off at 06:39:42 GMT. Later in the month, Soviet premier Nikita Khrushchev was visiting the United States. The US space program had had several recent setbacks including an on-pad explosion of an Atlas-Able rocket and
6396-511: The transmitter failed, thereby preventing further scientific use of the spacecraft. In September 2007, Japan launched the SELENE spacecraft, with the objectives "to obtain scientific data of the lunar origin and evolution and to develop the technology for the future lunar exploration", according to the JAXA official website. In 2023, Smart Lander for Investigating Moon (SLIM) is a lunar lander mission of
6478-550: Was followed by Chandrayaan-3 , the third lunar exploration mission by the Indian Space Research Organisation. It also carried the lander named Vikram and the rover named Pragyan , and achieved the country's first soft landing near the south polar region of the Moon. The Ballistic Missile Defense Organization and NASA launched the Clementine mission in 1994, and Lunar Prospector in 1998. NASA launched
6560-479: Was printed on 14 kilometres (8.7 mi) of teletype , which were analysed and published in spring 1960. According to Donald William Cox, Americans were starting to believe that they were making progress in the Space Race and that although the Soviet Union might have had larger rockets, the United States had better guidance systems, but these beliefs were questioned when the Soviets were able to impact Luna 2 on
6642-475: Was similar engravings on aluminium strips which were embossed on the last stage of the Luna 2 rocket. The scientists took extra, unspecified precautions in preventing biological contamination of the Moon. There was difficulty getting Luna 2 ready for launch. The first attempt on September 6 failed due to a loose electrical connection. A second attempt two days later also went awry when the core stage LOX tank failed to pressurize properly due to ice formation in
6724-461: Was the fourth launch attempt and the first partial success of the program. It launched on 2 January 1959 and missed the Moon by 5,965 kilometres (3,706 mi). One mission separated Luna 1 and Luna 2 , a launch failure that occurred with an unnamed probe on 18 June 1959. Luna 2 would be the Soviet Union's sixth attempt to impact the Moon. It was the second of the Ye-1a series, modified to carry
