South Korean spacecraft fueled for Cape Canaveral trip to the moon – Spaceflight Now

A South Korean spacecraft because of launch to the moon subsequent week from Cape Canaveral has been loaded with the gasoline it must maneuver right into a low-altitude lunar orbit for imaging and scientific observations.

The Korea Pathfinder Lunar Orbiter, or KPLO, spacecraft is scheduled to launch at 7:08 p.m. EDT (2308 GMT) subsequent Thursday, August 4, aboard a SpaceX Falcon 9 rocket from Cape Canaveral House Pressure Station. . Mission officers mentioned earlier this week that the launch was delayed two days to permit SpaceX time to finish extra work on the Falcon 9 rocket.

Technicians and engineers working inside SpaceX’s Payload Processing Facility just lately accomplished refueling the Korean lunar probe, following the spacecraft’s supply to Cape Canaveral from South Korea on June 6 July.

The spacecraft was loaded with hydrazine gasoline inside SpaceX’s clear room. South Korean engineers who traveled to the launch base with the KPLO spacecraft additionally carried out the ultimate exams on the probe, the primary South Korean mission to the Moon and the primary journey in area exploration. distant.

The 1,495-pound (678-kilogram) spacecraft was to be encapsulated contained in the Falcon 9 rocket’s payload fairing after refueling. The aeroshell will shield the spacecraft through the ultimate part of launch preparations and through the first minutes of the launch itself.

Subsequent, SpaceX will transport the payload module from the processing facility to the Falcon 9 rocket’s hangar a couple of miles away, the place floor crews will join the spacecraft contained in the rocket’s nostril cone to the rocket. Falcon 9 higher stage.

All the rocket will then deploy and be elevated vertically to Pad 40 at Cape Canaveral. The KPLO mission is one among two launches presently scheduled for subsequent Thursday on the Florida Spaceport. A United Launch Alliance Atlas 5 rocket with a US army satellite tv for pc is predicted to raise off about 12.5 hours earlier than the Falcon 9 rocket on the KPLO mission.

A part of the aim of the KPLO mission is in its identify. The mission is a scout, or precursor, for South Korea’s future ambitions in area exploration, which embody a robotic moon touchdown within the early 2030s. South Korea has additionally signed to hitch the agreements NASA-led Artemis and will contribute to the US area company’s human lunar exploration program.

The KPLO mission can also be named after Danuri, a mixture of the phrases “dal” and “nurida” in Korean, that means “benefit from the moon”.

“The essential concept of ​​this mission is expertise growth and demonstration,” mentioned Eunhyeuk Kim of the Korea Aerospace Analysis Institute. “Moreover, through the use of the scientific devices, we hope to acquire helpful knowledge on the lunar floor.”

The mission carries six science devices and expertise demonstration payloads.

KPLO will take a look at a brand new South Korean spacecraft platform designed for deep area operations, in addition to new communication, management and navigation capabilities, together with validation of an “interplanetary web” connection utilizing a disturbance-tolerant community.

The scientific aims of the mission embody mapping the lunar floor to assist choose future touchdown websites, learning sources equivalent to water ice on the moon, and exploring the radiation setting close to from the moon.

The $180 million (233.3 billion gained) mission will launch to the moon on a low-power, fuel-efficient ballistic lunar switch trajectory, a path launched by NASA’s small CAPSTONE spacecraft , a expertise demonstration mission launched final month on a Rocket Lab mission and is predicted to orbit the moon in November.

If KPLO is launched within the first week of August, its date of arrival on the Moon is ready for December 16. The Falcon 9 will launch the spacecraft on a trajectory that can take it near the Lagrange level L1, a gravitationally secure location virtually one million miles (1.5 million kilometers) from the daytime aspect of Earth, about 4 occasions farther than the moon.

Gravitational forces will naturally pull the spacecraft again to Earth and the Moon, the place the Korean probe will probably be captured in orbit on December 16. A collection of propulsive maneuvers with the spacecraft’s thrusters will steer KPLO right into a low-altitude round orbit of roughly 60 miles. (100 kilometers) from the lunar floor to New Yr’s Eve.

After a month of commissioning and testing, the spacecraft’s year-long major science mission is scheduled to start round February 1. If the orbiter has sufficient gasoline, mission officers might take into account an prolonged mission from 2024, Kim mentioned.

One of many KPLO mission payloads, or Danuri, is a US-built instrument referred to as ShadowCam.

Derived from NASA’s Lunar Reconnaissance Orbiter important digicam, ShadowCam will peer inside darkish craters close to the lunar poles, the place earlier missions have detected proof of water ice deposits. The NASA-funded ShadowCam instrument is lots of of occasions extra delicate than LRO’s digicam, permitting it to gather high-resolution, high-signal-to-noise photographs of the interiors of still-dark craters utilizing mirrored gentle .

NASA additionally supplies monitoring and communications assist for the KPLO mission via its Deep House Community antennas in California, Spain and Australia. KARI, the South Korean area company, additionally has its personal deep-space communications antenna, but it surely doesn’t provide the continual protection of NASA’s world community.

South Korea started growing the KPLO mission in 2016 for a deliberate launch in 2020, however officers delayed the mission after the spacecraft exceeded its authentic launch weight, and engineers wanted extra time to finish detailed design work.
