NASA to make observations from space junk collision with Moon
NASA said it aimed to investigate the crater that formed when the wreckage of a SpaceX rocket was expected to crash into the moon in early March, calling the event “an exciting research opportunity.”
The rocket, which was deployed in 2015 to put a NASA satellite into orbit, has its second stage, or booster, afloat in the universe, the common fate of this type of space technology.
“On the current trajectory, the second stage is expected to hit the far side of the moon on March 4, 2022,” a NASA spokesman told AFP.
The impact of the 4-ton rocket block cannot be seen in real time from Earth, nor will NASA’s Lunar Reconnaissance Orbiter (LRO), which is currently orbiting the Moon, “watch the impact as it happens.” the spokeswoman said.
However, LRO can be used later to capture images for before and after comparison.
Finding the crater “will be challenging and could take weeks to months,” the spokesman said, adding that “this unique event presents an exciting research opportunity.”
Studying craters formed by spattering objects of known mass and velocity (which would travel 9,000 kilometers per hour), as well as material churned by impacts, could help advance lunar science, or the scientific study of the moon.
Spacecraft have deliberately crashed into the Moon before for scientific purposes, such as testing seismometers during the Apollo missions, but this is the first accidental collision to be detected.
Astronomer Bill Gray, creator of software used to determine the trajectories of asteroids and other objects, was the first to calculate the booster’s new collision course with the moon.
He believes that space junk should always point towards the moon if possible: “If it hits the moon, then we can actually learn something from it,” Gray said.

Patterns of behaviour that emerge after trauma
Trauma is a deeply distressing or disturbing experience that can leave a lasting impact on a person’s mental and emotional health. It can result from a range of events, such as natural disasters, accidents, physical or emotional abuse, or military combat. Trauma can have a significant effect on a person’s behavior and can manifest in various ways. Here are some patterns of behavior that often emerge after trauma:
- Hyperarousal: After experiencing trauma, a person may feel constantly on edge, with heightened levels of anxiety and tension. This can manifest as irritability, restlessness, and difficulty sleeping.
- Avoidance: Trauma can also cause a person to avoid situations, people, or places that remind them of the traumatic experience. This can lead to social withdrawal, isolation, and a loss of interest in previously enjoyable activities.
- Emotional numbness: Trauma can cause a person to feel emotionally disconnected or numb, making it difficult for them to experience positive emotions such as joy or love.
- Hypervigilance: A person who has experienced trauma may be hyper-aware of their surroundings and perceive threats where none exist. This can lead to an increased sense of danger, which can trigger anxiety or panic attacks.
- Flashbacks: Trauma can cause a person to experience vivid and intrusive memories of the traumatic event. These flashbacks can be triggered by a range of stimuli, such as sights, sounds, or smells.
- Guilt and shame: Trauma can cause a person to experience feelings of guilt, shame, and self-blame. They may feel responsible for what happened to them, even when it was beyond their control.
- Substance abuse: Trauma can lead to the use of drugs or alcohol as a way of coping with difficult emotions. This can quickly become a self-destructive pattern of behavior that exacerbates the trauma.
It’s important to note that not everyone who experiences trauma will display all of these behaviors, and that each person’s response to trauma is unique. However, recognizing these patterns of behavior can help individuals and their loved ones identify when trauma may be a contributing factor to mental and emotional health challenges. Seeking professional support, such as therapy or counseling, can help individuals process their trauma and learn healthy coping mechanisms to manage their behavior.
