Falcon 9 -A Lunar Impactor

Falcon 9 -A Lunar Impactor Falcon 9   A SpaceX Falcon 9 rocket, carrying Firefly Aerospace's Blue Ghost and ispace's Resilience lunar landers, streaks into orbit after lifting off from Launch Complex 39A at the Kennedy Space Center in Cape Canaveral, Florida, on January 15, 2025 A stray piece of a SpaceX rocket is thought to have crashed into the Moon this morning after hurtling through space for more than 18 months. The section of the Falcon 9 rocket believed to have hit the Moon is its upper stage (the bit that doesn't return to Earth to land) - which is about the size of a five-storey building. Impact The impact is believed to have occurred at about 07:35 BST 5 August 2026, with the object travelling at about 2.43 kilometres per second - or 5,400mph (8,700 km/h). Its collision with the Moon's surface is the result of the gentle push and pull of gravity and sunlight after SpaceX launched two US-Japanese lunar landers in January 2025. Danger Nasa insists the crash pose...

Spirulina - NASA proposed that it could be grown in space for use by astronauts.

Spirulina - NASA proposed that it could be grown in space for use by astronauts. Spirulina is a type of algae that grows in fresh or salt water. It comes as a supplement, in tablet or powder form. People use it for its health benefits, as it is rich in nutrients and has antioxidant properties. Spirulina is among the world’s most popular supplements. It is made from an organism that grows in both fresh and saltwater. Contains Spirulina is packed with nutrients. A single tablespoon (tbsp), or 7 grams (g), of dried spirulina powder, contains. Protein: 4 g Thiamin: 14% of the Daily Value (DV) Riboflavin: 20% of the DV Niacin: 6% of the DV Copper: 47% of the DV Iron: 11% of the DV It also contains small amounts of magnesium, potassium, and manganese In addition, the same amount contains only 20 calories and less than 2 g of carbohydrates. Spirulina also provides a small amount of fat — around 1 g per tbsp (7 g) — including both omega-6 and omega-3 fatty acids in an approximately 1.5 to 1 ra...

Life size telepresence

Life size telepresence  Life-sized telepresence Holoportaion uses advanced 3D holographic projection and real-time video capture systems like ARHT Media and Teleportel to beam a person into a remote room as a life-sized, three-dimensional interactive figure.  Not Teleportation It is not physical matter teleportation, which remains restricted to subatomic quantum information. How Holographic Telepresence Works? 1) Real-time capture : High-definition cameras record a speaker or user in a studio or specialized booth. 2) Data streaming : The video and audio feed streams live across standard high-speed internet networks. 3) Life-sized display : Proprietary light and glass setups project the person in 3D, creating proper eye-contact and physical depth without wearing a headset. . Current Applications Global conferencing : Business leaders and educators beam into remote stages or classrooms instantly. Virtual receptionists : Automated or live-beamed staff greet visitors in office lo...

Weather balloon causing pollution?

Weather balloon causing pollution? No of weather balloon launch center all over the world. - 900 No of weather balloon launched each day 2 per day,per center Total number of balloon launched each day World wide 1800 What are weather balloon made of? Latex : The most common material, which gives the balloon the high elasticity needed to expand up to 20 feet in diameter before popping. Neoprene (Chloroprene): A synthetic rubber used for its durability and better resistance to extreme temperatures and ozone in the upper stratosphere. Polyethylene : Used for specialized, massive scientific balloons (like those used by NASA) that are meant to float for long durations at extremely high altitudes without bursting. How much time it takes balloon decay? The decay time of the balloon's physical material (natural rubber latex) depends on the environment: On Land : Typically decomposes in 6 to 48 months. In Water/Oceans : Can take a year or more to degrade. Danger to Wildlife, and Environment...

The "Iron Man" Design System

The "Iron Man" Design System As in 'Iron Man movie' actor Tony Stark designed the Iron Man suit using holographic technique. Elon Musk has created a real-world hand-manipulated 3D interface. How it works :  Musk used motion-tracking sensors (such as a Leap Motion controller and an Oculus Rift headset) paired with specialized software to manipulate virtual 3D models of spacecraft parts in thin air. Instead of using a traditional mouse and keyboard, he used hand gestures to rotate, scale, and examine rocket components, which were then sent directly to a 3D printer to be manufactured in titanium. Musk used it to revolutionize aerospace design by allowing engineers to interact with digital blueprints as naturally as they would with physical objects. Compiled by Ms Naresh kuwar 

Weather balloon

Weather balloon What?  A weather balloon (or sounding balloon) is a high-altitude balloon made of flexible latex or neoprene, filled with helium or hydrogen.  It carries a small, battery-powered instrument package called a radiosonde to collect and transmit real-time data on atmospheric pressure, temperature, humidity, and wind speed. Why? Weather balloons provide crucial "upper air" data that cannot be captured by ground radar or satellites.  Meteorologists rely on these vertical atmospheric profiles to predict severe storms, winter precipitation (e.g., distinguishing between snow and freezing rain), and wind shear. How? Ascent : Launched from the ground, the balloon rises at about 5 meters per second, ascending into the stratosphere up to altitudes of 30,000 to 40,000 meters (100,000 to 130,000 feet). Expansion and Burst : As it rises and atmospheric pressure drops, the gas expands until the balloon stretches to roughly four times its original size and eve...

Facial Reconstruction - Forensic Science

Image
Facial reconstruction - Forensic Science  Facial reconstruction often called forensic facial approximation—is the process of recreating the face of an unknown individual from their skeletal remains to aid in identification or archaeological study.  The primary techniques are  - manual (clay sculpting)   - computer modeling (2D drawing, and 3D). 1. Manual Clay Sculpting (Physical 3D)This traditional method, often using the Manchester or Russian/Anatomical approaches, requires in-depth knowledge of physical anatomy, muscle structure, and anthropology. Process: The skull (or a high-quality cast replica) is mounted on a stand. Cylindrical pegs or markers representing standardized soft-tissue thicknesses are glued to anatomical landmarks on the skull. Modeling: Clay is then packed into the spaces between the markers to build up the mimicry of facial muscles, fat layers, and glands. Feature shaping: Specialized sculpting tools are used to add artificial ey...
