NASA Mars Perseverance rover celebrates one year on the Red Planet

NASA’s Mars Perseverance rover celebrated its year-long landing on the red planet on Friday, marking the year it began and stopped searching for evidence of ancient life on Mars.

The Perseverance rover will touch down on Mars at 3:55pm ET on February 18, 2021 in Jezero Crater, an ancient seabed that offers the best chance to search for signs of ancient life on the planet .

To celebrate, NASA is hosting a live Q&A tonight at 7:00pm PST/10:00pm EST, where scientists at NASA’s Jet Propulsion Laboratory will review mission highlights from the past year, And hopefully the previews come for the wanderers.

While Perseverance will naturally get a lot of attention, it’s not heading to Mars alone.

Shortly after landing, Perseverance deployed the Mars Ingenuity helicopter, which is scheduled to become the first aircraft to fly on another planet on April 19, 2021. That anniversary is still a few months away, but in many ways it doesn’t seem to be more important than persistence itself.

In addition to more than a dozen flights on Mars that far exceeded expectations, Ingenuity provided important data and experience operating autonomous drones on another planet.

That’s critical for the upcoming Dragonfly reconnaissance mission, which is scheduled to launch in 2026 and land on Saturn’s moon Titan in 2034.

While the search for ancient life on Mars is important work, Titan is a world so rich in organic matter that it even has its own methane-precipitating “water cycle”, stagnant bodies of liquid methane on the surface, and evaporation.

Many of these processes mirror many found on early Earth, and so may hold the key to understanding how prebiotic organic compounds leapfrog living organisms.

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.
