The dangers of Spacewalk

• Spacewalks are among the most hazardous activities that people can engage in. Astronauts who go on spacewalks encounter a variety of dangers, including:


Depressurization:


• If a spacesuit is pierced or otherwise damaged, the air inside the suit may be sucked out into space's vacuum. The astronaut would lose consciousness and die within seconds as a result of this.

Extreme temperature exposure:


• Temperatures in orbit can range from -270 degrees Fahrenheit under the Earth's shadow to 250 degrees Fahrenheit in direct sunlight. While on a spacewalk, astronauts must be careful not to overheat or freeze.

Radiation exposure:

• Harmful radiation


Harmful radiation such as solar radiation and cosmic rays, abounds in space. Astronauts during spacewalks are subjected to higher quantities of radiation than astronauts inside spacecraft. Cancer and other health problems may be exacerbated by this radiation.

Collision with space debris:


• Debris in orbit includes old satellites, rocket pieces, and other items. A collision with space debris could result in catastrophic damage or death for an astronaut.

Loss of mobility:

• Because space is weightless, astronauts can quickly lose their grip on objects and drift away. This could make tasks or returning to the spaceship difficult.


• Despite the dangers, spacewalks are necessary for spacecraft maintenance and repair, the construction of new structures in space, and the execution of scientific investigations.

• Spacewalkers receive considerable training to prepare them for the challenges they will confront.


Here are some measures astronauts do to reduce the risks of spacewalks:


•They wear pressurized spacesuits to protect themselves from the vacuum of space, and they utilize tethers to stay linked to the spacecraft. 

• They work in pairs so that they can assist each other in an emergency. They prepare their spacewalks meticulously and take all essential procedures to prevent risks.

• Spacewalks are an important part of space exploration, allowing astronauts to safely perform challenging tasks like repairing satellites, installing new equipment, and conducting scientific experiments.

• Despite risks like exposure to harmful chemicals and decompression sickness, these activities contribute significantly to our understanding of space.

Kilobots: The Swarm Robots That Could Chang e the World • Swarm robotics is a fast expanding topic of study that investigates the use of huge groups of robots to execute activities that would be difficult or impossible for a single robot to perform.  •The Kilobot, a tiny robot roughly the size of a quarter, is one of the most promising platforms for swarm robotics. • Kilobots are extremely simple machines. They have two vibrating motors to move about, an infrared sensor to interact with one another, and a light to signal to other robots. • Their simplicity, though, is also their strength. Kilobots can be utilized in vast numbers because they are inexpensive and simple to construct, giving them the ability to attack. • Self-assembly is one of the most astounding abilities of Kilobots. This implies they may be programmed to form various forms and patterns without the need for human involvement. • They can, for example, be programmed to create a square, a circle, or even a human face. • K

What's up with those alien bodies? Presented by Mexican Congress.

Image
•  The presentation of suspected alien bodies to the Mexican Congress has stirred considerable curiosity and debate. • Jaime Maussan, a Mexican writer and UFO enthusiast, originally revealed the remnants, which are little, humanoid-shaped animals with elongated skulls and three fingers on each hand, in 2017.  • Although Maussan maintains that the bodies were discovered in Peru, their origin and authenticity have been called into question by specialists. • Maussan and other researchers presented the bodies to the Mexican Congress again in November 2023, this time with fresh evidence that they think proved their legitimacy. • Photographs, X-rays, and DNA analysis are among the evidence. However, the scientific community is still skeptical. Some scientists have noted that the bodies resemble recognized animal remains, while others have questioned the DNA analysis's veracity. • The public's reaction to the exhibition of the claimed alien bodies has been varied. Some people believ

Chandrayaan 3 : one step closer to the Moon.

Image
• On July 14, 2023, Chandrayaan 3 was successfully launched from the Satish Dhawan Space Centre in Sriharikota, India. • On August 5, 2023, the spacecraft entered lunar orbit; on August 23, 2023, the lander soft-landed on the lunar surface at Singhasan, near the lunar south pole. The lander is carrying the Pragyan rover, which will spend up to 14 days exploring the lunar surface. The Chandrayaan 3 mission is scheduled to last for one year. • The successful launch and landing of Chandrayaan 3 is a significant achievement for India's space program. This mission will assist India in becoming a leader in lunar exploration. Here are some of Chandrayaan 3's scientific goals: • Look for water molecules on the lunar surface;  Research the geology and composition of the moon. • Conduct research on the lunar atmosphere and dust environment. • Gather lunar rock and soil samples. • The data obtained by Chandrayaan 3 will aid scientists in their understanding of the Moon's creation and
