South Korea joined the list of countries with ambitious plans in space, and it took to the moon on Thursday.

Its first lunar spacecraft, named Danuri, was flown toward space at the scheduled time at 7:08 p.m. ET by a SpaceX Falcon 9 rocket, which lifted off from Cape Canaveral Space Force Station in Florida. After about 40 minutes and a series of engine launches, the Korean spacecraft detached from the rocket’s second stage, and embarked on its journey to the moon.

When you reach lunar orbit, you will join a spacecraft from NASA, India and China that is currently exploring Earth’s companion. The Danuri science payload will study the moon’s magnetic field, measure the amounts of elements and molecules such as uranium, water and helium-3, and photograph dark craters at the poles where the sun never shines.

What is Danuri and what will it be taught?

Originally known as the Korean Lunar Pathfinder Orbiter, the mission has now been named Danuri, a combination of Korean words meaning “moon” and “enjoy.” It will be South Korea’s first space mission beyond low Earth orbit.

Its scientific instruments include a magnetometer, a gamma ray spectrometer and three cameras. NASA fitted one of the cameras, ShadowCam, which is sensitive enough to capture the few photons bouncing off the terrain into the moon’s permanently dark and shadowed craters. These craters, located at the moon’s poles, remain forever cold, below minus 300 degrees Fahrenheit, and contain water ice that has accumulated over the ages.

The ice could provide a frozen history of the 4.5-billion-year-old solar system, as well as plenty of resources for future visiting astronauts. Ice can also be mined and melted to provide water and broken down into oxygen and hydrogen, providing both breathing air for astronauts and rocket thrusters for travelers looking to blast off from the moon to other destinations.

What else has South Korea done in space?

South Korea is developing its own missiles. her first design, Naro-1, successfully reached orbit on the third attemptin 2013. Since then, the Korea Aerospace Research Institute – the South Korean equivalent of NASA – has shifted its efforts to the Nuri, a larger three-stage rocket. The Nouri’s second trip In June, he succeeded in putting several satellites into orbit.

South Korea has several communications and Earth observation satellites in low Earth orbit. It also has a file Extensive military missile program.

How many countries have sent missions to the moon?

The United States and the Soviet Union sent several robotic spacecraft to the Moon beginning in the 1960s. NASA’s Apollo Program Sends Astronauts There from 1968 until 1972. Then the world almost completely lost interest in the moon for three decades, but the buzz of activity returned.

In the past few years, China has sent several successful robotic spacecraft, including three landers. NASA has sent several orbital vehicles there and is recruiting commercial companies to send payloads to the lunar surface in the coming years.

Japan and the European Space Agency launched lunar missions, and India sent two orbiters to the moon, although a lander accompanying the second orbiter crashed during its descent to the surface in 2019.

Another mission in 2019, Beresheet, the lander built by the Israeli non-profit organization, SpaceIL, also crashed while trying to land on the moon.

Why does it take so long for Danuri to reach the moon?

The spacecraft is taking a long, energy-efficient route to the Moon. It first heads toward the sun, then returns around to be captured in a lunar orbit in mid-December. This “ballistic trajectory” takes longer but does not require launching a large engine to slow the spacecraft when it reaches the moon.

Danuri will then adjust its orbit 62 miles above the lunar surface. The main scientific mission is scheduled to last for one year.

What will go to the moon this year?

A small NASA-funded spacecraft, CAPSTONE, is on its way to the Moon to explore a highly elliptical orbit, as NASA plans to build a lunar base for future astronauts. It is scheduled to reach lunar orbit in November.

But this year’s big event will be Artemis 1, an unmanned test of the giant NASA rocket and capsule that will bring astronauts back to the Moon in the coming years. NASA aims to launch in late August or early September.

Two commercial companies, ispace of Japan and Intuitive Machines of Houston, hope to launch small robotic landers to the moon late this year.
