(CNN)China successfully launched its Chang’e-5 lunar mission Tuesday to collect rocks from the moon — the first attempt by any country since the 1970s.
The unmanned Chang’e-5 probe, named after the mythical Chinese goddess of the moon, blasted off from the Wenchang Spacecraft Launch Site in Hainan, near the country’s southern tip, in the early morning. After liftoff, the spacecraft separated from its boosters and protective fairing, and went into Earth-moon transfer orbit. Live-streamed footage from the launch shows the Chinese teams and engineers applauding in the control room when the boosters fell away from each side of the rocket, and again when the spacecraft separated from the rocket in orbit.Crowds watch in the early hours of the morning as the rocket carrying Chang’e-5 launches. Once in the moon’s orbit, the probe will deploy a pair of vehicles to the surface to drill into the ground and collect soil and rock samples. If successful, the mission will make China only the third country to have retrieved lunar samples, following the United States and the Soviet Union decades ago.Read MoreUS astronauts brought back 382 kilograms (842 pounds) of rocks and soil during the Apollo program, between 1969 and 1972, while the Soviet Union collected 170.1 grams (6 ounces) of samples in 1976. In the decades since, data from orbital remote sensing missions has shown there is a much greater diversity of rock types and ages on the moon than existing samples suggest. The Chang’e-5 probe will attempt to collect 2 kilograms (4.5 pounds) of samples in a previously unvisited area of the moon — a massive lava plain known as Oceanus Procellarum, or “Ocean of Storms.” According to NASA, this large dark spot, stretching about 2,900 kilometers (1,800 miles) wide, could be a scar from a giant cosmic impact that created an ancient sea of magma.These samples could help scientists understand more about the moon’s origins and foundations — and set the foundation for more complex sample retrieval missions in the future, potentially on other planets.A month-long missionThe spacecraft is made up of an orbiter, a lander, an ascender and a returner, according to the China National Space Administration (CNSA). When Chang’e-5 enters the moon’s orbit, the spacecraft will separate in two: the orbiter-returner combination will stay in space, orbiting about 200 kilometers (about 124 miles) above the moon’s surface, while the lander-ascender combination will descend and land on the Ocean of Storms. This is expected to happen by early December, according to Chinese state-run news agency Xinhua.Within 48 hours of the lander-ascender’s touchdown, its robotic arm will scoop up rocks from the surface, and a drill will bore into the ground to collect soil. The samples will be sealed into a container in the spacecraft.The Long March 5 rocket carrying Chang’e 5 is seen on the launch pad at the Wenchang Space Launch Site on Hainan. The ascender will then take off, re-enter orbit, and dock with the orbiter-returner. At that stage, the samples will be transferred to the returner, and the ascender will separate, leaving the orbiter-returner to start the journey back to Earth. The returner will eventually separate, re-enter our atmosphere, and land in China.From start to finish, the mission will last more than 20 days, according to Xinhua.When the samples are returned to Earth, scientists will be able to analyze the structure, physical properties, and material composition of the moon’s soil, the CNSA said. The mission may help answer questions such as how long the moon remained volcanically active in its interior, and when its magnetic field — key to protecting any form of life from the sun’s radiation — dissipated.”Unmanned rendezvous and docking in lunar orbit will be a historic first. It will be very difficult,” said Peng Jing, deputy chief designer of the probe, in the Xinhua report. “We could call it a milestone mission. Its success will help us acquire the basic capabilities for future deep space exploration such as sampling and takeoff from Mars, asteroids and other celestial bodies.”China’s space ambitionsChina was late to the space race — it didn’t send its first satellite into orbit until 1970, by which time the US had already landed an astronaut on the moon — but it has caught up fast.Buoyed by billions of dollars in government investment, China has rapidly accelerated its space program over the past decade, firing space labs and satellites into orbit. China's far side of the moon mission is just the start of its space ambitions Speaking to astronauts aboard the Shenzhou 10 spacecraft by video link in 2013, Chinese President Xi Jinping said, “the space dream is part of the dream to make China stronger.””The Chinese people will take bigger strides to explore further into the space,” he added.Last year, China became the first country to send an unmanned rover to the far side of the moon. And in July this year, China launched its first unmanned mission to Mars — the Tianwen-1 probe, which will orbit the planet before landing a rover on the surface. It’s expected to reach the Red Planet next February.If Tianwen-1 is successful, Beijing has plans to eventually send a manned mission to Mars. Plans are also underway to launch a permanent space station by 2022, and send astronauts to the moon by the 2030s.If successful, China would become only the second country, after the US, to put a citizen on the moon.
