China’s National Space Administration (CNSA) is planning an asteroid diversion mission with a target launch date of 2030. The mission will involve two separate operations: the first will see a spacecraft impact an asteroid, while the second will observe space rocks to gain a deeper understanding of the solar system and asteroid formation.
The primary target for this mission is asteroid 2015 XF261, which is approximately 30 meters in size. This asteroid was documented by the Jet Propulsion Laboratory (JPL) in the Small Object Database. On July 9th, it passed Earth at a distance of roughly 50 million kilometers (31 million miles), traveling at a speed of around 42,000 kilometers per hour (26,000 miles per hour), which is regarding 30 times the speed of sound.
China’s ambition to develop asteroid impact or deflection technology has been publicly known for some time. The CNSA has confirmed that the mission is intended for both scientific research and the creation of a defense once morest potential future asteroid threats to Earth.
Wu Weiren, director of the China Deep Space Exploration Laboratory (DSEL), has announced that China’s asteroid 2015 XF261 impact mission is expected to occur around 2027 or before 2030. This timing aligns with the orbital path of asteroid 2015 XF261, which is scheduled to make another close approach to Earth in March and May of 2027, and once more in April 2028. During this latter approach, asteroid 2015 XF261 will be approximately 21 million kilometers from Earth. However, the most opportune moment for the mission is believed to be in April 2029, when asteroid 2015 XF261 will be within approximately 7.1 million kilometers of Earth.
It is worth noting that NASA has already successfully conducted the DART mission, or the Dimorphos Asteroid Impact Mission, within the Didymos binary asteroid system. This mission successfully altered the asteroid’s orbit, marking a significant milestone in the field of planetary defense.
Further, the European Space Agency (ESA) is scheduled to launch the Hera spacecraft in October 2024, which will be sent to the Didymos binary asteroid system to conduct a further assessment of the impact caused by the DART mission. Hera is expected to rendezvous with the asteroids Dimorphos and Didymos in 2026.

China’s Ambitious Asteroid Diversion Mission: A Double-Barreled Approach
China is set to make a significant leap in planetary defense with its ambitious asteroid diversion mission, planned for launch by 2030. This ambitious project will involve two distinct missions, targeting the asteroid 2015 XF261, a space rock roughly 30 meters in size.
What’s the Plan?
While the mission is primarily focused on scientific exploration and advancement in asteroid deflection technology, its implications for Earth’s safety are significant. Here’s a breakdown of the two-pronged approach:
Mission 1: Impact and Analysis
- A spacecraft, specifically designed for this purpose, will be sent on a collision course with 2015 XF261.
- The impact will be carefully orchestrated to alter the asteroid’s trajectory, demonstrating the feasibility of this technique for future planetary defense scenarios.
- The collision will be meticulously monitored from Earth and other space-based platforms.
- This mission will provide invaluable data on asteroid composition, internal structure, and the effectiveness of kinetic impactors in altering their orbits.
Mission 2: Observation and Research
- A dedicated spacecraft will be deployed to observe 2015 XF261 from a safe distance.
- This observational mission will focus on studying the asteroid’s characteristics, including its shape, rotation, surface composition, and any potential moons or satellites.
- The data gathered will contribute to our understanding of asteroid formation and evolution in the early solar system.
- This mission will complement the impact mission by providing a comprehensive picture of the asteroid’s behavior before and following the collision.
Why 2015 XF261?
The selection of 2015 XF261 as the target asteroid was based on several factors:
- Its relatively small size makes it a suitable candidate for an impact mission without posing a significant threat to Earth.
- The asteroid’s orbital path brings it relatively close to Earth, offering a practical target for testing deflection techniques.
- It is categorized as a “Near-Earth Object” (NEO) by the Jet Propulsion Laboratory (JPL), and its movement is well-documented in the Small Object Database.
China’s Expertise in Asteroid Impact Technology
China has been developing asteroid impact or deflection technology for some time, with the CNSA confirming its importance for both scientific advancement and safeguarding Earth from potential asteroid threats. This mission builds upon China’s expertise in space exploration and its growing commitment to planetary defense.
The Timing of the Mission
The mission is scheduled to take place around 2027 or before 2030, ideally coinciding with 2015 XF261’s close approach to Earth in April 2029. This timing will allow for optimal observation and analysis during the mission’s critical phases.
Learning from NASA’s DART Mission
China’s mission draws inspiration from NASA’s successful DART (Double Asteroid Redirection Test) mission, which demonstrated the feasibility of altering an asteroid’s orbit through kinetic impact.
The DART mission targeted the Didymos binary asteroid system, successfully impacting the smaller asteroid, Dimorphos, and changing its orbital period. The mission was a significant step towards developing effective planetary defense strategies.
The European Space Agency (ESA) is also playing a role in this endeavor. Their Hera spacecraft, set to launch in October 2024, will rendezvous with the Didymos binary asteroid system in 2026, further assessing the impact of the DART mission.
Global Collaboration in Planetary Defense
China’s asteroid diversion mission highlights the growing global collaboration in planetary defense. These ambitious projects demonstrate the collective commitment of nations to safeguard our planet from potential celestial threats.
Looking Ahead
China’s asteroid diversion mission is a testament to the country’s advancements in space exploration and its commitment to planetary defense. The data gathered from this project will provide valuable insights into asteroid characteristics, behavior, and the effectiveness of deflection technologies. These insights will contribute significantly to our understanding of these celestial objects and bolster our global efforts to protect Earth from future asteroid threats.
