China’s Chang’e 6 Return To Earth With Lunar Soil from Far Side of the Moon

China achieved another milestone in its ambitious space program on Tuesday, successfully bringing a capsule filled with lunar soil from the far side of the moon back to Earth. This latest success, part of a mission by the China National Space Administration’s Chang’e 6 lander, underscores China’s growing capabilities in space exploration and adds to a series of nearly flawless lunar missions that began in 2007.

Chang’e 6’s mission, which lasted 53 days, marks the first time in human history that samples have been returned from the far side of the moon. Long Xiao, a planetary geologist at China University of Geosciences, hailed this as a major event for scientists worldwide and a cause for celebration for all humanity.

China’s Steady Lunar Progress Fuels Scientific Advances and Global Space Race

The success of this mission opens up new possibilities for international lunar sample exchanges and advances scientific understanding of the solar system. However, this achievement is also seen in some quarters, notably Washington, as a significant milestone in a 21st-century space race with geopolitical overtones.

China’s methodical and steady approach to lunar exploration, which includes plans to land more robots and eventually human astronauts on the moon, contrasts with other nations’ efforts. For instance, in February, a privately operated American spacecraft landed on the moon, and NASA is pursuing its Artemis campaign to return Americans to the lunar surface. However, NASA’s next mission, a flight by astronauts around the moon, has been delayed due to technical issues.

Building towards its lunar ambitions, China has executed a robotic lunar exploration program devised decades in advance. The Chang’e program, named after the Chinese moon goddess, began with missions to orbit the moon and photograph and map its surface.

From Chang’e 3 to Chang’e 5, Pioneering Moon Missions and Historic Achievements

In 2013, Chang’e 3 successfully touched down on the near side of the moon and deployed the rover Yutu-1. This was followed in 2019 by Chang’e-4, which became the first vehicle to visit the moon’s far side and put the Yutu-2 rover on the surface. In 2020, Chang’e-5 landed on the moon and sent nearly 1.8 kg of near-side lunar regolith back to Earth, making China the third country after the US and the Soviet Union to achieve such a feat.

Technical Glitches Delay NASA’s Return Mission from ISS

Meanwhile, the United States is grappling with its own set of challenges in space exploration. Problems with Boeing’s Starliner capsule, currently docked at the International Space Station (ISS), have disrupted the original plans for its return to Earth with astronauts Sunita Williams and Barry Wilmore. NASA has postponed the planned return three times and currently has not set a new date. Since its June 5 launch, the capsule has experienced five helium leaks, five failed maneuvering thrusters, and a propellant valve that failed to close completely, necessitating extensive fixes and tests.

Starliner, designed to remain docked at the ISS for up to 45 days, could extend this period to 72 days if absolutely necessary, relying on various backup systems. Internally at NASA, the latest targeted return date for Starliner is July 6. Originally planned for an eight-day mission, this would extend the mission to nearly a month.

A Crucial Test for NASA’s Astronaut Capsule

The propulsion system issues at the heart of Starliner’s problems involve the craft’s service module, which is essential for backing the capsule away from the ISS and positioning it for reentry into Earth’s atmosphere. Overheating thrusters and helium leaks, linked to their usage frequency, have posed significant challenges. Despite recent test-firings providing some confidence in a safe return, the mission team in Houston, comprising NASA and Boeing personnel, continues to scrutinize data and consider potential fixes, including software updates and hardware usage modifications.

This mission marks Starliner’s first orbit with astronauts, a critical test for NASA to certify it as its second ride to the ISS alongside SpaceX’s Crew Dragon. Despite the propulsion issues, NASA has maintained that Starliner remains capable of returning the astronauts to Earth if necessary, whether as an escape pod in an emergency or if any of its perishable components show signs of expiring earlier than planned.

Starliner Challenges and China’s Lunar Triumph Highlight Global Competition

Should Starliner be deemed unsafe for return, an alternative would be to send the astronauts home aboard Crew Dragon, which ferried four astronauts to the ISS in March and has the capacity to accommodate additional passengers in an emergency. Although this scenario is considered unlikely, it would be a significant setback for Boeing, reminiscent of the 2022 incident when a NASA astronaut had to use an alternative ride home due to a coolant leak in Russia’s Soyuz capsule.

As China celebrates its latest lunar success and the US navigates challenges with Starliner, the global space race continues to unfold. These developments highlight the competitive and collaborative dynamics at play in humanity’s quest to explore and understand the cosmos.
