‘Potentially Hazardous’ Asteroid That Recently Zipped Past Earth Is An Elongated Weirdo With An Odd Rotation

by Rida Fatima

The asteroid 2011 AG5's close approach to Earth on February 3
(Fig 1: The asteroid 2011 AG5’s close approach to Earth on February 3 was captured in a collage of six planetary radar observations (Image credit: NASA/JPL-Caltech).)

A group of astronomers recently had the opportunity to closely examine a potentially dangerous asteroid as it passed by Earth. The asteroid, named 2011 AG5, caught their attention because it is elongated and rotating more slowly than expected. This asteroid was first discovered by the Mount Lemmon Survey in Arizona in 2011, and at the time, it made headlines because it was predicted to be on a dangerous trajectory towards Earth in 2040 due to its orbit around the sun taking about 621 days. However, upon conducting further research back in 2012, astronomers discovered the error in the calculation of its orbit, and that it does not actually threaten Earth. Despite not posing a threat, the anomaly of this asteroid has caught the attention of astronomers, who are interested in studying it further to better understand its unusual shape and rotation (Baker, 2023).

On February 3, 2023, an asteroid passed by Earth at a distance of around 1.1 million miles (1.8 million kilometers), which is approximately five times as far as the moon is from Earth. This close proximity to our planet gave astronomers an opportunity to observe and scan it in detail for the first time. Prior to this close flyby, scientists had limited information about the asteroid’s characteristics and properties, but this new observation could provide valuable insights. By closely studying the asteroid’s composition, shape, and rotation, researchers can gain a better understanding of its origins, and potentially learn more about the history and evolution of our solar system. The close encounter also allowed astronomers to confirm that the asteroid is not on a collision course with Earth, giving us a sense of relief that there is no immediate threat from this particular space rock.

Unusual Characteristics of Asteroid 2011 AG5 During Close Flyby of Earth

Asteroid 2011 AG5's orbit and current location as of June 15, 2012
(Fig 2: Asteroid 2011 AG5’s orbit and current location as of June 15, 2012 (Image credit: NASA/JPL-Caltech).)

A study conducted by researchers using NASA’s Deep Space Network facility in California has shed new light on the characteristics of asteroid 2011 AG5. The scientists used a powerful Goldstone Solar System Radar antenna dish to capture images of the asteroid during its close flyby of Earth on February 3, 2023. The images revealed that the asteroid is approximately 500 meters long and 150 meters in width, it can be estimated as big as the Empire State Building in size. What surprised the researchers was the unusual elongated shape of the asteroid, which is unlike most other near-Earth objects that have been observed to date. Lance Benner, a principal scientist at NASA’s Jet Propulsion Laboratory, lead the research with his expertise, commented that “this is one of the most elongated near-Earth objects we’ve seen out of the 1,040 near-Earth objects that planetary radar has detected so far”.

Despite the surprising discovery, the scientists are not jumping to any conclusions about why the asteroid has such an unusual and unexpected size and shape until they have more time to dig into the information. The findings from this observation has the complete potential to provide new insights into the formation and evolution of asteroids in our solar system, and perhaps even help us better understand the threat posed by potentially hazardous near-Earth objects.

New Radar Scans Reveal Slow Rotation and Surface Features of Asteroid 2011 AG5

The recent radar scans of asteroid 2011 AG5 conducted by NASA’s Deep Space Network facility have revealed new insights about its rotation and surface features. According to the scans, the asteroid takes around 9 hours for the completion of its single rotation, it is considered a much longer time as compared to other asteroids. The elongated shape of the asteroid may have an influence on its slow rotation, although the exact reason is not clear. The surface of the asteroid was visible in dark and light patches in the new images, which would point to the presence of numerous small-scale features on the body of the asteroid. However, the researchers are uncertain about what these features are. The scientists hope that the new data collected from the radar scans will enable them to better predict the asteroid’s future trajectory, which could help to explain its unusual characteristics (Shawn, 2023).

The latest ranging calculations obtained by the team working on the planetary radar system will help researchers to better predict the asteroid’s trajectory and track its movements, particularly when it passes closer to Earth in 2040. The director of NASA’s Center for Near Earth Object Studies (CNEOS) – Paul Chodas at JPL, emphasized that new data will provide more insights into the asteroid’s properties and definitely maximize the opportunities to better understand this peculiar space rock. Moreover, the asteroid is not considered a direct threat to Earth, because of its size and closeness to earth it is taken as a “potentially hazardous asteroid” it will pass within 1.1 million km of Earth during its next flyby in 2040. As such, it is essential for astronomers to continue monitoring the asteroid’s movements and studying its characteristics to better understand the potential risks posed by other near-Earth objects in the future.

Now, NASA and DARPA have announced their latest collaboration to demonstrate a nuclear thermal rocket engine in space, which will enable NASA’s crewed missions to Mars. The partnership will be through the Demonstration Rocket for Agile Cislunar Operations (DRACO) program. This non-reimbursable agreement outlines the roles, responsibilities, and processes for both agencies to speed up development efforts. The collaboration between NASA and DARPA on nuclear propulsion technology will help drive forward NASA’s goal to send humans to Mars.

Under the agreement, NASA’s Space Technology Mission Directorate (STMD) will lead the technical development of the nuclear thermal engine, which will be integrated with DARPA’s experimental spacecraft. DARPA will act as the contracting authority for the development of the entire stage and the engine, which includes the reactor. DARPA will be leading the overall program, which includes rocket systems integration and procurement, approvals, scheduling, and security. They will also cover safety and liability, ensuring the engine’s overall assembly and integration with the spacecraft. Throughout the development process, NASA and DARPA will collaborate on the assembly of the engine before the in-space demonstration, which is expected to occur as early as 2027.

The partnership between NASA and DARPA is crucial for the advancement of space technology, as the space domain is critical to modern commerce, scientific discovery, and national security. With this collaboration, the two agencies will leverage their combined expertise gained from many previous space nuclear power and propulsion projects to efficiently and quickly transport materials to the Moon and, eventually, people to Mars.

Benefits of Nuclear-Powered Rocket

The use of a nuclear thermal rocket engine offers several benefits over traditional chemical propulsion systems.

  • Firstly, it allows for faster transit times, reducing the risk for astronauts on long space missions. This reduction in transit time is crucial for human missions to Mars as longer trips require more supplies and more robust systems.
  • Secondly, a nuclear thermal rocket engine increases science payload capacity and provides higher power for instrumentation and communication.

In a nuclear thermal rocket engine, a fission reactor is used to generate extremely high temperatures. The engine then transfers the heat produced by the reactor to a liquid propellant, which is expanded and exhausted through a nozzle to propel the spacecraft. Nuclear thermal rockets can be three or more times more efficient than conventional chemical propulsion systems, making them a more attractive option for space missions.

This new technology also supports NASA’s Fission Surface Power project and the Department of Energy’s (DOE) commercial design efforts to develop nuclear power plant concepts that could be used on the surface of the Moon and Mars. NASA and the DOE are also working on another commercial design effort to advance higher-temperature fission fuels and reactor designs as part of the nuclear thermal propulsion engine, with the goal of increased engine performance in the future.

The benefits of a nuclear thermal rocket engine are numerous and include faster transit times, increased science payload capacity, higher power for instrumentation and communication, and increased efficiency compared to traditional chemical propulsion systems. NASA and DARPA’s collaboration on the DRACO program will help to advance this technology and make crewed missions to Mars a reality.

Previous Nuclear Thermal Rocket Engine Tests

It’s important to note that the last tests of nuclear thermal rocket engines in the United States were conducted over 50 years ago. The tests were carried out under NASA’s Nuclear Engine for Rocket Vehicle Application and Rover projects. Despite these earlier efforts, the technology has advanced significantly since then and has paved the way for new developments in space nuclear technology.

One notable reference is the Rover program, which was developed during the 1960s and 70s. The program aimed to demonstrate the feasibility of using nuclear reactors to power space missions, and it was responsible for developing and testing nuclear thermal rocket engines. The project was considered a success as it was able to demonstrate the potential of the technology, but it was eventually cancelled due to budget constraints.

Another reference is the Nuclear Engine for Rocket Vehicle Application (NERVA) program. This program was also developed during the 1960s and 70s and aimed to demonstrate the feasibility of nuclear thermal rocket engines for space missions. The program was a joint effort between NASA and the Department of Energy (DOE) and resulted in the development of several prototype nuclear thermal rocket engines.

Overall, these previous efforts and the technological advancements over the past 50 years have helped lay the foundation for the current collaboration between NASA and DARPA to test a nuclear-powered rocket engine. The knowledge gained from these earlier projects has played a significant role in shaping the development of new space nuclear technology, and the DRACO program represents a significant step forward in the advancement of nuclear thermal rocket engine technology.
