2025 promises to be a year filled with remarkable space exploration milestones and astronomical phenomena. From new space missions to captivating celestial events, here are the most anticipated happenings that space enthusiasts should mark on their calendars.
The Top Upcoming Space Events of 2025
1. Artemis III: NASA’s First Crewed Lunar Landing in Over 50 Years
NASA’s Artemis III mission is set to make history as the first crewed lunar landing since the Apollo program. Scheduled for late 2025, Artemis III aims to land astronauts near the lunar South Pole, where water ice may be present. The mission will involve the Space Launch System (SLS) rocket and the Orion spacecraft, with astronauts transferring to SpaceX’s Human Landing System (HLS) for the descent to the Moon’s surface. This mission is crucial in establishing a sustained human presence on the Moon, paving the way for future Mars expeditions.
2. SpaceX’s Starship Mars Mission: First Cargo Mission to the Red Planet
Elon Musk’s ambitious Mars mission with SpaceX is expected to see its first cargo deployment to Mars in 2025, contingent on ongoing testing and regulatory approvals. Starship, SpaceX’s fully reusable spacecraft, will aim to deliver essential equipment and possibly establish infrastructure for human habitation on Mars. This mission will be a critical test of Starship’s capabilities and mark a significant step in making Mars colonization a reality.
3. China’s Tianwen-3 Mars Sample Return Mission Launch
Following the success of Tianwen-1, China is planning Tianwen-3, a mission to retrieve samples from Mars and return them to Earth. Slated for launch in late 2025, this mission will involve complex maneuvers, including a Mars landing, sample collection, and a return to Earth by 2028. If successful, China will become the second country, after the United States, to bring Martian samples back, contributing valuable data on Mars’ geology and potential signs of past life.
4. ExoMars Rover (Rosalind Franklin) Landing on Mars
The European Space Agency’s (ESA) ExoMars Rover, named Rosalind Franklin, is anticipated to land on Mars in 2025 after delays in recent years. Equipped with a drill capable of reaching depths of up to two meters, the rover’s primary objective is to search for signs of life on Mars. The rover will analyze subsurface soil and rock samples, which could offer insights into Mars’ past environments and its habitability.
5. OSIRIS-REx’s Apophis Encounter
After its successful asteroid sample return mission, NASA’s OSIRIS-REx spacecraft will head towards asteroid Apophis, which will pass close to Earth in 2025. Though the spacecraft won’t arrive until 2029, this mission serves as a precursor to study Apophis’ composition and orbital changes. Apophis is considered a “potentially hazardous” asteroid, and studying it could enhance our understanding of near-Earth objects and potential future impacts.
6. Solar Eclipses: Total and Partial Across the Globe
2025 will feature two solar eclipses: a total eclipse on August 12 and a partial eclipse on March 29. The August total eclipse will be visible across parts of the Arctic, Greenland, and Iceland. Skywatchers in North America, Europe, and parts of Asia will witness the partial eclipse, offering a spectacular opportunity for astronomy enthusiasts and photographers to capture these phenomena.
7. Perseids and Geminids: The Brightest Meteor Showers
The Perseids and Geminids meteor showers, two of the most anticipated annual meteor events, will reach peak visibility in August and December, respectively. The Perseids, known for their high rate of bright, fast meteors, will peak around August 12. The Geminids, often regarded as the best meteor shower due to their high activity and slower meteors, will peak around December 13-14. Both showers are expected to offer thrilling night sky displays with favorable conditions for observing.
8. Launch of the European Space Agency’s Athena X-ray Observatory
ESA’s Athena (Advanced Telescope for High Energy Astrophysics) is set to launch in 2025, aiming to observe the high-energy universe. Focusing on X-ray astronomy, Athena will study supermassive black holes, galaxy clusters, and the evolution of the cosmos. This observatory will address some of the most profound questions about the universe’s structure and behavior by probing X-ray emissions from the most energetic and distant cosmic objects.
9. The First Test Launch of Blue Origin’s Orbital Rocket, New Glenn
Blue Origin’s New Glenn rocket, a reusable heavy-lift launch vehicle, is expected to conduct its first test launch in 2025. Designed for both crewed and uncrewed missions, New Glenn will compete in the commercial space sector, carrying large payloads to orbit and beyond. This inaugural flight will be closely watched, as it positions Blue Origin to compete with SpaceX in the spaceflight industry.
10. India’s Gaganyaan Crewed Mission
The Indian Space Research Organisation’s (ISRO) Gaganyaan mission is scheduled to be India’s first crewed space mission, aiming to place Indian astronauts in low Earth orbit for a brief mission duration. This landmark mission will elevate India’s status in space exploration, making it the fourth country to independently send humans to space. Gaganyaan is expected to set the stage for future crewed and deep space missions by ISRO.
Conclusion
From the return of lunar landings to ambitious Martian missions, 2025 is set to be a transformative year in space exploration. These events not only mark technological milestones but also deepen our understanding of the universe. Whether you’re an astronomy enthusiast or simply curious about space, these top events of 2025 promise to inspire awe and spark further interest in humanity’s journey beyond Earth.
