Space Exploration's Biggest Year Yet: Missions to Watch in 2026

A New Era of Lunar Ambition

2024 marks a pivotal year for lunar exploration, with multiple nations and private entities targeting the Moon. Following India's successful Chandrayaan-3 landing in 2023, the race to the lunar south pole intensifies. NASA's Artemis program is central to this, with the uncrewed Artemis II mission scheduled to orbit the Moon. This mission will pave the way for Artemis III, which aims to return humans to the lunar surface later in the decade, including the first woman and person of color.

Beyond NASA, Japan's SLIM (Smart Lander for Investigating Moon) mission, having already made a precise landing, continues to gather data. Russia, despite recent setbacks, has indicated plans for future lunar probes. Furthermore, commercial ventures are increasingly playing a role. Companies like Intuitive Machines and Astrobotic are launching robotic landers under NASA's Commercial Lunar Payload Services (CLPS) program, delivering scientific instruments and technology demonstrations to the lunar surface. These missions are crucial for understanding lunar resources, particularly water ice, which is vital for future long-duration human outposts.

Deep Space Frontiers: Asteroids, Moons, and Beyond

While the Moon captures significant attention, deep space missions continue their ambitious journeys. NASA's Europa Clipper, slated for launch in late 2024, is designed to conduct detailed reconnaissance of Jupiter's moon Europa, a prime candidate for hosting extraterrestrial life due to its subsurface ocean. The mission will perform dozens of close flybys, gathering data on Europa's ocean, ice shell, and potential plumes.

Elsewhere, the OSIRIS-REx mission, having successfully returned samples from asteroid Bennu in 2023, is now embarking on an extended mission to asteroid Apophis. This extended mission, renamed OSIRIS-APEX, will study Apophis up close following its close approach to Earth in 2029. These asteroid missions provide invaluable insights into the early solar system and potential planetary defense strategies. China's Tianwen-2 mission, expected to launch in the coming years, also aims for an asteroid sample return.

The Commercial Space Boom Continues

The commercial space sector is not only supporting government initiatives but also driving innovation independently. SpaceX continues its rapid development of Starship, aiming for orbital flights throughout 2024. Successful orbital tests are critical for its envisioned roles in lunar missions, Mars colonization, and satellite deployment. Other private companies, such as Blue Origin with its New Glenn rocket, are also progressing with heavy-lift launch vehicle development, promising increased access to space.

Satellite constellations, particularly for internet services like Starlink and OneWeb, will see continued expansion, further populating low Earth orbit. This rapid growth also necessitates careful monitoring of space debris and the development of sustainable space practices. The increasing number of private astronauts and space tourists underscores the growing accessibility of space for non-governmental entities.

Earth Observation and Climate Science from Orbit

Beyond exploration, Earth observation satellites continue to provide critical data for understanding our planet and combating climate change. Missions like NASA's PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) observatory, launched in early 2024, are designed to study ocean biology and atmospheric aerosols with unprecedented detail. These missions provide vital information on ocean health, air quality, and the global carbon cycle.

The European Space Agency (ESA) and other international partners are also launching new generations of Earth observation satellites, focusing on areas like ice sheet monitoring, sea-level rise, and forest cover changes. The continuous flow of data from these orbital observatories is indispensable for climate modeling, disaster preparedness, and informed environmental policy-making, making 2024 a significant year not just for leaving Earth, but for understanding it better from above.
