2023 was a groundbreaking year for space exploration, with several high-profile missions achieving major milestones. NASA, SpaceX, China, India, the UAE, and others expanded our understanding of the solar system and unlocked new capabilities for future expeditions.
NASA Achieves Decades-Long Goal of Returning Samples from Asteroid
After a seven-year journey, NASA’s OSIRIS-REx spacecraft successfully returned pristine samples from the asteroid Bennu in September. This marked the agency’s first asteroid sample return mission, achieving a goal scientists had pursued since the early 2000s.
The samples will help reveal secrets about our solar system’s early formation over 4.5 billion years ago. Analysis so far has uncovered ingredients for water and organics like amino acids that may have seeded life on Earth.
China and NASA Both Target Lunar South Pole
China landed a robotic rover in the Moon’s south polar region for the first time ever as part of its Chang’e 5 lunar exploration program. The 14-day Chang’e 5 mission investigated the lunar surface and subsurface for water and other resources.
Meanwhile, NASA continued progress towards landing astronauts at the south pole by 2025 under the Artemis program, a key stepping stone to the agency’s goal of establishing a sustained human presence on and around the Moon.
These parallel efforts signal increasing strategic interest in the Moon’s rich resources and environment. They pave the way for advanced scientific discovery and long-term settlement.
Commercial Crews Reach ISS as Space Tourism Accelerates
The rise of commercial spaceflight reached new heights as SpaceX sent its sixth full private crew to the International Space Station (ISS) under its partnership with space tourism company Axiom Space.
With competition heating up, orbital habitats like the ISS could soon supportexpanding space science and commerce, thanks to redundant access now provided by both SpaceX and Boeing.
More broadly, over a dozen humans traveled to suborbital space or orbital space as fare-paying spaceflight participants in 2023. As costs continue to fall rapidly, experts predict space tourism could become commonplace this decade.
| Year | Suborbital Space Participants | Orbital Space Participants | Total Space Participants |
|---|---|---|---|
| 2021 | 0 | 0 | 0 |
| 2022 | 31 | 12 | 43 |
| 2023 | 48 | 15 | 63 |
Japan and UAE Achieve First Lunar Missions
The Japan Aerospace Exploration Agency (JAXA) placed a small transformable lunar robot into orbit around the Moon. Meanwhile, the UAE successfully inserted an orbiter around the Moon, making history as the first Arab nation to reach another celestial body.
These milestones symbolize both nations’ rising space capabilities and intent to access critical lunar resources like water ice. Along with India, their moonshot efforts could presage an “Asian space race” this decade.
Starship and SLS Inch Closer to Operational Status
Development of SpaceX’s next-generation Starship vehicle progressed rapidly towards orbital flight capability. Meanwhile, NASA’s beleaguered Space Launch System (SLS) finally achieved its first successful launch for the Artemis I uncrewed test mission around the Moon.
Both super heavy-lift vehicles aim to launch massive payloads needed for ambitious exploration like lunar outposts or crewed Mars missions. If realized, their operational status in 2023 could massively expand future deep space ambitions.
Webb Space Telescope Delivers Groundbreaking Discoveries
A little over a year after its launch, the revolutionary James Webb Space Telescope (JWST) has already profoundly expanded our view of the early universe. Its observations suggest galaxies started forming sooner and faster than expected after the Big Bang. JWST also analyzed atmospheric content of exoplanets and discovered one of the oldest galaxies ever detected.
As the world’s most complex and powerful space science observatory to date, these early results only scratch the surface of JWST’s potential. Its unmatched infrared vision will likely yield paradigm-shifting discoveries about cosmic origins for years to come.
Outlook for 2024: Moon Rush Accelerates
With global powers jockeying for position this past year, the Moon looks set to become the next space exploration focal point. 2024 will likely see even more actors attempt increasingly ambitious lunar activities.
China plans to launch the Chang’e 6 sample return mission, while India hopes to finally land a rover as part of Chandrayaan-3. NASA expects to launch the CAPSTONE cubesat to test unique lunar orbits for the Gateway outpost. The agency also aims to debut key Artemis 2 and 3 test flights around and on the Moon. Meanwhile, commercially-built lunar landers and orbiters will also join the fray.
From satellites to settlements, humanity’s return to the Moon after over 50 years looks poised to kick into high gear. The projects undertaken now appear destined to form the bedrock for a sustained, expansive lunar presence that will unlock its vast scientific and economic potential.
