Nasa transmite pela internet pouso de sonda no asteroide Bennu

A Nasa, agência espacial norte-americana, vai transmitir a partir das 18h (horário de Brasília), desta terça-feira, o pouso da sonda OSIRIS-REx na superfície do asteroide Bennu.

O pouso é um dos momentos mais complexo da missão que teve início em 2016. Os cientistas estudaram diversos registros da superfície do asteroide para encontrar um região um pouco mais plana e com uma menor concentração de rochas. O local pré-determinado tem o tamanho de algumas vagas de estacionamento e fica dentro da cratera Nightngale.

Assim que o equipamento concluir a descida, um braço mecânico será acionado para coletar cerca de 60 gramas de rochas e areia. Esse material será estudado quando for trazido para a Terra em setembro de 2023 e pode dar pistas sobre a origem do universo. O Bennu é tratado pelos pesquisadores como uma cápsula do tempo que armazena informações de mais de 4,5 bilhões de anos

Apesar de o pouso levar bastante tempo, a coleta da amostra será muito rápida. Os cientistas estimam que levará cerca de 16 segundos será suficiente para a retiradas do material da superfícies do asteroide e o armazenamento de forma segura.

A parte mais importante da missão será transmitida pelo canal do YouTube da Nasa e também será compartilhada no Twitter da OSIRIS-REx

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
