Age Research cards 7-11 years Moon landings - Luna 9 About Credit-Pline On the 3 February 1966, Luna 9 made history by being the first crewless space mission to make a soft landing on the surface of the Moon. It was the ninth mission in the Soviet Union’s Luna programme (the previous five missions had all experienced spacecraft failure). The Soviet Union existed from 1922 to 1991 and was the largest country in the world; it was made up of 15 states, the largest of which was the Russian Republic, now called Russia. The Space Race is a term that is used to describe the competition between the United States of America and the Soviet Union which lasted from 1955 to 1969, as both countries aimed to be the first to get humans to the Moon. Working scientifically The Luna 9 spacecraft had a mass of 98kg (about outwards to make sure the spacecraft was stable the same as a baby elephant) and it carried before it began its scientific exploration. communication equipment to send information back to Earth, a clock, a heating system, a power The camera on board took many photographs of source and a television system. The spacecraft the lunar surface including some panoramic included scientific equipment for two enquiries: images. These images were transmitted back to one to find out what the lunar surface was like; Earth using radio waves.

The Apollo 11 mission was part of the United States of America’s National Aeronautics and Space Administration (NASA) Project Apollo. Commander Neil Armstrong and pilot Buzz Aldrin landed the Apollo lunar lander known as Eagle on the lunar surface while Michael Collins flew the command module known as Columbia in orbit around the Moon. Armstrong was the first human to step on the surface of the Moon; as he made that historical step, he said the famous phrase: “That’s one small step for [a] man, one giant leap for mankind”. Working scientifically Eagle, the Apollo lunar lander, had a number of One of these minerals was named armalcolite after different pieces of equipment onboard so that the three astronauts; all three of these minerals Armstrong and Aldrin could collect data and make have since be discovered on Earth. observations for a number of different enquires. This included a television camera that collected Buzz Aldrin set up the Early Apollo Surface footage of the lunar surface and recorded the Experiments Package (EASEP) which included astronauts carrying out tasks and working equipment for two more enquiries.

Age Research cards 7-11 years Moon landings - Apollo 15 About Credit-NASA On 30 July 1971, Apollo 15 became the fourth crewed spacecraft to land on the surface of the Moon. The Apollo 15 mission was part of the United States of America’s National Aeronautics and Space Administration (NASA) Project Apollo. It was the first extended mission and astronauts David Scott, Alfred Worden and James Irwin spent three days exploring the Moon. Scott and Irwin explored the surface of the Moon using the first lunar rover while Worden orbited the Moon in the command module, Endeavor. On the way home, Worden was the first astronaut to perform a spacewalk in deep space. Working scientifically Having a lunar rover enabled the astronauts to Apollo experiments still being used today. They are explore a much larger area than on previous used to make measurements that allow missions. The rover carried television cameras so astronomers to carefully track the Moon’s that geologists on Earth could follow Scott and movement and its distance from Earth. Irwin’s exploration.

These reflectors were left behind the objects down. The hammer and feather hit the at all of the Apollo landing sites and are the only ground at the same time. Research cards SELENE (Kaguya) Moon landings - Age 7-11 years JAXA About Credit- SELENE was a crewless, lunar orbiter that was developed by the Japanese Aerospace Exploration Agency (JAXA). The spacecraft was launched on 14 September 2007 and after successfully orbiting the Moon for a year and eight months, it impacted into the lunar surface on the 10 June 2009. In Japan, the spacecraft is better known by its nickname Kaguya which is also the name of the lunar princess in the ancient Japanese folktale ‘The tale of the Bamboo cutter’. Working scientifically The Kaguya spacecraft carried many different angles of objects on the Moon’s surface. It was this pieces of equipment for making measurements. equipment that help the mission discover an enormous cave, 50km long and 100m wide. JAXA By analysing the light that was reflected from the said that they thought the cave could be turned Moon’s surface, Kaguya was able to collect data so into an exploration base for astronauts. Kaguya that the rocks that cover the entire lunar surface collected lots of data from the cave and scientists could be identified. This equipment was able to are quite sure that the structure is solid and safe. accurately identify the different chemicals that can The cave would protect astronauts from extreme be found on the lunar surface.
