James Webb Space Telescope Fully Deploys Sunshield, to Unfold Secondary Mirror Today

The James Webb Space Telescope has completed the complex process of deploying its kite-shaped sunshade. The sun visor is about the size of a tennis court and has five floors. The first three were initially deployed, and the last two were completed late last night. The deployment of all five layers is critical to the US$10 billion (approximately Rs 74,525 crore) space observatory. The sunshade will keep the telescope cool enough to start capturing images of distant stars and planets.

NASA said that on the tenth day after the telescope that replaced the Hubble telescope was boxed and launched by the Ariane 5 rocket, the tightening of the shading layer was completed. Although the completion of this process eliminated a lot of failed space, it will take about a month for the James Webb Space Telescope to reach a fully deployed state.

“That’s it: we have just finished one of the most challenging steps in our journey into the universe. After all five layers of sun visors have been tightened, about 75% of our 344 single-point failures have been scrapped,” Aerospace The bureau wrote on Twitter. The tension of the sun visor is a victory for space engineering. Many people initially doubted its success because the design involved the use of a large number of motors, gears, cables, and other equipment. Engineers spent years testing the design and proving that the skeptics were wrong.

James Webb Sun Visor Manager James Cooper has previously stated that the tensioning phase of the sun visor is challenging because of the interaction between several components.

The sun visor helps to cool the telescope. The temperature on the hot side of the sun or the shield can reach up to 110 degrees Celsius, while the temperature can be as low as -236 degrees Celsius. This incredible temperature shift is achieved by a five-layer sun visor covering nearly six feet.

Patterns of behaviour that emerge after trauma

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
