South Korea Launches First Moon Mission on SpaceX Rocket

Joining the listing of countries with formidable plans in area, South Korea set off for the moon on Thursday.

Its first lunar spacecraft, named Danuri, was carried towards area on time at 7:08 p.m. Eastern time by a SpaceX Falcon 9 rocket, which launched from Cape Canaveral Space Force Station in Florida. After about 40 minutes and a collection of engine firings, the Korean spacecraft separated from the rocket’s second stage, embarking on its journey to the moon.

When it arrives in lunar orbit, it would be a part of spacecraft from NASA, India and China which might be at present exploring Earth’s companion. Danuri’s scientific payload will examine the moon’s magnetic area, measure portions of components and molecules like uranium, water and helium-3, and {photograph} the darkish craters on the poles the place the solar by no means shines.

Originally generally known as the Korea Pathfinder Lunar Orbiter, the mission has now been given the title of Danuri, a portmanteau of the Korean phrases for “moon” and “enjoy.” It will likely be South Korea’s first area mission to transcend low-Earth orbit.

Its scientific devices embrace a magnetometer, a gamma-ray spectrometer and three cameras. NASA equipped one of many cameras, ShadowCam, which is delicate sufficient to select up the few photons that bounce off the terrain into the moon’s darkish, completely shadowed craters. These craters, situated on the moon’s poles, stay ceaselessly chilly, under minus 300 levels Fahrenheit, and comprise water ice that has amassed over the eons.

The ice may present a frozen historical past of the 4.5 billion-year-old photo voltaic system and a bounty of assets for future visiting astronauts. Such ice can be extracted and melted to offer water and damaged aside into oxygen and hydrogen, which would offer each air to breathe for astronauts and rocket propellants for vacationers trying to launch from the moon to different locations.

South Korea is growing its personal rockets. Its first design, Naro-1, efficiently reached orbit on the third strive, in 2013. Since then, the Korea Aerospace Research Institute — South Korea’s equal of NASA — has shifted its efforts to Nuri, a bigger, three-stage rocket. The second Nuri flight in June efficiently positioned a number of satellites in orbit.

South Korea has a number of communications and earth remark satellites in low-Earth orbit. It additionally has an intensive navy missile program.

The United States and the Soviet Union despatched quite a few robotic spacecraft to the moon starting within the Sixties. NASA’s Apollo program despatched astronauts there from 1968 by 1972. The world then nearly fully misplaced curiosity within the moon for 3 a long time, however a hubbub of exercise has returned.

In the previous few years, China has despatched a number of profitable robotic spacecraft, together with three landers. NASA has despatched a number of orbiters there and has enlisted business firms to ship payloads to the lunar floor within the coming years.

Japan and the European Space Agency have launched moon missions, and India has despatched two orbiters to the moon, though a lander accompanying the second orbiter crashed because it descended towards the floor in 2019.

Another mission in 2019, Beresheet, a lander constructed by an Israeli nonprofit, SpaceIL, additionally crashed because it tried to land on the moon.

The spacecraft is taking a protracted, energy-efficient path to the moon. It first heads towards the solar, then loops again round to be captured in lunar orbit in mid-December. This “ballistic trajectory” takes longer however doesn’t require a big engine firing to sluggish the spacecraft when it will get to the moon.

Danuri will then alter its orbit to an altitude of 62 miles above the moon’s floor. The fundamental scientific mission is scheduled to final for one 12 months.

A small NASA-financed spacecraft, CAPSTONE, is en path to the moon to discover a extremely elliptical orbit, the place NASA plans to construct a lunar outpost for future astronauts. It is scheduled to reach in lunar orbit in November.

But the massive occasion of the 12 months will likely be Artemis 1, an uncrewed check of NASA’s big rocket and capsule which might be to take astronauts again to the moon within the coming years. NASA is aiming to launch in late August or early September.

A few business firms, ispace of Japan and Intuitive Machines of Houston, are additionally hoping to launch small robotic landers to the moon late this 12 months.
