Chang’E-6 to Launch May 3, Complete Phase 3 of Chang’E Lunar Program

China’s Chang’E-6 orbiter, return capsule, lander, ascender and its international payloads are set to launch aboard a Long March 5 from Wenchang Space Launch Center, Hainan Island at 19° N as early as May 3. Launch mass is estimated to be 8,200 kg with the lander at ~3,200 kg. The mission is a backup of the Chang’E-5 mission and will be the first to attempt to collect and return regolith from the far side of the Moon. It will aim to retrieve up to 2kg within 48 hours of landing from the Apollo impact crater within the South Pole-Aitken basin. The international payloads on this mission are the roving laser retroreflector from Italy, ICUBE-Qamar (ICUBE-Q) from Pakistan, an instrument to detect negative ions on lunar surface from ESA / Sweden, and a radon detector from France. The Queqiao-2 relay satellite in a lunar elliptical frozen orbit of 200 × 16,000 km will support communications for CE-6 and future missions for at least 10 years. There are 4 phases of the Chang’E program and CE-6 will be the last of Phase 3. Phase 4 includes CE-7 and CE-8 missions for the construction of the International Lunar Research Station starting in 2026. ILRS has participation from 12 member nations and 12 NGOs to date, and its development is planned with 5 crucial missions (ILRS 1-5) between 2030-2035 the last of which includes the establishment of “lunar-based astronomy and Earth observation capabilities”.

Is it Time to Expand Artemis Accords Membership?

The broadest and most diverse international human space exploration coalition in history according to the US State Department, the Artemis Accords now include 39 countries: 18 in Europe (Italy, Luxembourg, UK, Ukraine, Poland, Romania, France, Czech Republic, Spain, Germany, Iceland, Netherlands, Bulgaria, Belgium, Greece, Switzerland, Sweden, Slovenia), 8 in Asia (Japan, UAE, South Korea, Israel, Bahrain, Singapore, Saudi Arabia, India), 5 in South America (Brazil, Colombia, Ecuador, Argentina, Uruguay), 3 in North America (USA, Canada, Mexico), 3 in Africa (Nigeria, Rwanda, Angola) and 2 in Oceania (Australia, New Zealand). In contrast to the other major effort organizing to explore the Moon, the China and Russia-led International Lunar Research Station (ILRS), the Artemis Accords are currently limited to national membership – with application of expressed principles “to apply to civil space activities conducted by the civil space agencies of each signatory”. If Artemis were broadened to include non-governmental organizations (NGOs) such as academic institutions, commercial interests, and non-profits, momentum towards realization of 21st century human Moon landings and multi-world civilization may be bolstered. With recent reports of major reevaluation of the architecture needed to achieve the Artemis goal of returning man and sending the first woman and person of color to the lunar surface, now may be an opportune time to also readjust the nature of the Accords themselves, harnessing collective energy of both “the established and emerging actors in space”.
