Vi isso hoje!
Fantástico dia para a Ciência...
Só tenho pena que o Stephen Hawking não tivesse vivido mais um pouco para ver esta imagem...

Arecibo telescope collapses, ending 57-year run

Já se esperava que acontecesse, por causa da falta de manutenção. E hoje aconteceu.
Perdemos uma das obras de engenharia e ciência mais icónicas da nossa era.

Sim já era esperado...
Com a falta de suporte internacional para projectos nesse radiotelescópio, o investimento foi sendo cada vez mais reduzido, já á tempos uma das partes que sustinha o receptor, tinha rebentado, o inevitável iria acontecer...
É uma pena, pois sempre deu para fazer vários estudos...
Agora não sei o que será dele... possívelmente será deixado ao abandono...
Cumprimentos,

NASA lands Perseverance rover on the Mars surface, carrying the first helicopter for another planet

NASA successfully landed its fifth robotic rover on Mars on Thursday, with the U.S. space agency confirming that Perseverance touched down safely on the red planet’s surface.“Touchdown confirmed,” NASA’s Jet Propulsion Laboratory mission control said. “Perseverance safely on the surface of Mars, ready to begin seeking the sands of past life.”
The rover is the most technologically advanced robot that NASA has ever sent to Mars, with the agency aiming to spend nearly two years exploring the surface. The agency spent about $2.4 billion to build and launch the Perseverance mission, with another $300 million in costs expected for landing and operating the rover on the Mars surface.
Based on its predecessor Curiosity, which reached Mars in August 2012 and is still in operation, the Perseverance rover was built by NASA’s JPL in California. Multiple companies contributed to parts of the spacecraft, such as the Lockheed Martin-built heat shield, Aerojet Rocketdyne-built rocket thrusters and the Maxar Technologies-built robotic arm.
Perseverance is also carrying a small helicopter named Ingenuity, which NASA plans to use to attempt the first flight on another planet.
The rover is about the size of a small car, weighing about one ton in total and is 10 feet long by nine feet wide by seven feet tall. It has a robotic arm that reaches about seven feet long, the end of which has a robotic “hand” that has a camera, chemical analyzer, and a rock drill. Perseverance is nuclear powered, with a plutonium generator provided by the U.S. Department of Energy to generate electricity for its pair of lithium-ion batteries.
Perseverance traveled 293 million miles to reach Mars over the course of more than six months since launching on a United Launch Alliance Atlas V rocket on July 30.
