South Korea’s first Moon mission is coming soon, the SpaceX Falcon 9. launch with

TEMPO.CO, Jakarta South Korea’s first Moon mission is about to arrive. The Korea Pathfinder Lunar Orbiter (KPLO), which will probe the Moon, is scheduled to launch from a SpaceX Falcon 9 rocket on August 2, 2022.

The mission is seen as the first step in South Korea’s ambitious space agenda, which also includes a robotic moon landing in 2030 and an asteroid sample return mission.

KPLO already has an official name, “Danuri”, which is a mixture of two Korean words meaning “moon” and “enjoy.” It will fly with a total of six payloads. Five were developed by Korean universities and research organizations, including the Korean Aerospace Research Institute (KARI), and one from NASA.

The six experiments are the Lunar Terrain Imager (LUTI), the Wide-angle Polarimetric Camera (Polcam), a magnetometer known as KMAG, a gamma ray spectrometer known as KGRS, the Disruption Tolerant Network Experiment Payload (DTNPL) and a high-sensitivity camera. Funded by NASA called ShadowCam.

While in space, Danuri would orbit the Moon for at least a year, if everything went according to plan. The main function of the orbiter is to measure the magnetic forces above the surface of the Moon and to assess lunar resources such as water ice, uranium, helium-3, silicon and aluminum, as well as topographic data to help determine future lunar landing sites. To make a map.

After the launch of Falcon 9, it will take some time to reach the Moon. Daanuri will use a ballistic lunar transfer path, which will eventually reach lunar orbit in mid-December.

The Korean Aerospace Research Institute (KARI), headquartered in Daejeon, delivered about 33 pounds (15 kg) of payload mass to NASA on the orbiter.

In September 2016, NASA issued a request for a science instrument designed to increase knowledge about the distribution of volatiles such as water, including transferring those resources to the Moon’s permanent shadow regions (PSRs) and where they How are you trapped?

The result was that NASA chose ShadowCam, an instrument developed by Arizona State University and San Diego-based Malin Space Science Systems. ShadowCam will acquire images of the Moon’s shadow regions using high-resolution cameras, telescopes and highly sensitive sensors.

The instrument’s optical camera is based on the Narrow Angle Camera (NAC) aboard NASA’s Lunar Reconnaissance Orbiter (LRO). NAC has been producing images of the Moon for more than 13 years, now the new camera for KPLO is more sensitive.

ShadowCam will collect high-resolution images of the permanent shadow region as it flies about 62 miles (100 kilometers) above the Moon’s surface for about a year, said Prasoon Mahanti, ShadowCam deputy principal investigator at Arizona State University in Tempe.

“The Moon’s Permanent Shadow Zone (PSR) usually exists at the bottom of host craters and topographical depressions where sunlight never reaches. This makes this region very cold and therefore a favorable location for volatile species, For example water, methane and ammonia.” are trapped in the cold for long geological time,” said Mahanti.

The ShadowCam will help in the search for water ice in polar craters by mapping the reflectance in the PSR, Mahanti said. Shadow regions are only indirectly illuminated by light reflected from nearby topographic features.

Secondary lighting is just a reflection of this, of course, too dim. However, the ShadowCam is optimized for imaging in low light conditions, being 200 times more sensitive than the NAC LRO, one of two cameras that make up the Lunar Reconnaissance Orbiter Camera System, or the older orbiter’s LROC.

“Like the LROC NAC, which has transformed our understanding of the Moon by collecting an unprecedented number of high-resolution lunar images, ShadowCam is set to provide the first high-resolution view of permanently shadowed regions in very dark regions of the Moon. The co-worker will be. Moon. Moon,” said Mahanti.

Ben Busey, a ShadowCam investigator at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said ShadowCam will not only look for evidence of water. Another goal is to identify hazards and determine traffic capabilities within the PSR, potentially helping mission planners plan travel in and out of the facility by future explorers.

“The more retrospective data we can have from this challenging area, the more efficient we will be with our exploration,” Bassi said. “Permanently shaded areas will never be easier.”
