Becoming a member of the checklist of countries with formidable area plans, South Korea left for the moon on Thursday.
Its first lunar spacecraft, named Danuri, was blasted into area at 7:08 p.m. Jap Time by a SpaceX Falcon 9 rocket, which launched from Cape Canaveral Area Pressure Station in Florida. . After about 40 minutes and a sequence 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 can be at the moment exploring Earth’s companion. Danuri’s science payload will examine the moon’s magnetic subject, measure quantities of components and molecules like uranium, water and helium-3, and {photograph} darkish craters on the poles the place the solar would not shine. by no means.
What’s Danuri and what’s going to he examine?
Initially generally known as the Korea Pathfinder Lunar Orbiter, the mission has now been given the title Danuri, a portmanteau of the Korean phrases for “moon” and “get pleasure from.” It is going to be the primary South Korean area mission to transcend low Earth orbit.
Its scientific devices embrace a magnetometer, a gamma spectrometer and three cameras. NASA supplied one of many cameras, ShadowCam, which is delicate sufficient to choose up the few photons bouncing off the bottom within the moon’s darkish, completely shadowed craters. These craters, positioned on the moon’s poles, at all times stay chilly, beneath minus 300 levels Fahrenheit, and include water ice that has gathered over eons.
The ice might present a frozen historical past of the photo voltaic system’s 4.5 billion years and an abundance of assets for future visiting astronauts. This ice may also be mined and melted to offer water and damaged into oxygen and hydrogen, which would offer each air for astronauts to breathe and rocket boosters for vacationers looking for to blast off from the planet. moon to different locations.
What else has South Korea carried out in area?
South Korea is creating its personal rockets. Its first design, Naro-1, managed to achieve orbit on the third attempt, in 2013. Since then, the Korea Aerospace Analysis Institute – the South Korean equal of NASA – has shifted its efforts to Nuri, a rocket taller with three flooring. The second Nuri flight in June efficiently positioned a number of satellites into orbit.
What number of international locations have despatched missions to the moon?
America and the Soviet Union despatched many robotic spacecraft to the Moon beginning within the Nineteen Sixties. NASA’s Apollo program despatched astronauts there from 1968 to 1972. The world then misplaced curiosity nearly totally for the Moon for 3 a long time, however a hubbub of exercise returned.
Lately, China has despatched a number of profitable robotic spacecraft, together with three landers. NASA has despatched a number of orbiters there and employed industrial firms to ship payloads to the lunar floor within the coming years.
Japan and the European Area Company have launched lunar missions, and India has despatched two orbiters to the moon, though a lander accompanying the second orbiter crashed because it descended to the floor in 2019.
One other mission in 2019, Beresheet, a lander constructed by Israeli nonprofit SpaceIL, additionally crashed whereas attempting to land on the moon.
Why will it take so lengthy for Danuri to get to the moon?
The spacecraft takes a protracted, energy-efficient path to the moon. It first heads in direction of the solar, then loops round to be captured in lunar orbit in mid-December. This “ballistic trajectory” takes longer however doesn’t require massive engines to gradual the spacecraft because it arrives on the moon.
Danuri will then alter its orbit to an altitude of 62 miles above the moon’s floor. The primary scientific mission is deliberate for a interval of 1 12 months.
What else goes to the moon this 12 months?
A small NASA-funded spacecraft, CAPSTONE, is on its option to the moon to discover a extremely elliptical orbit, the place NASA plans to construct a lunar outpost for future astronauts. It’s anticipated to reach in lunar orbit in November.
However the massive occasion of the 12 months will likely be Artemis 1, an uncrewed take a look at of NASA’s large rocket and capsule that’s to return astronauts to the Moon in years to return. NASA is aiming for a launch in late August or early September.
Two industrial firms, Japan’s ispace and Houston’s Intuitive Machines, additionally hope to launch small robotic landers on the moon later this 12 months.
