Remembering the crew of Soyuz 11, the only astronauts to die in space
The ill-fated replacement crew of Soyuz 11 spent three weeks performing experiments on the world's first space station. But their return trip ended in tragedy.

Fission surface power (FSP) can reliably provide us with the energy needed in all of these different contexts. A fission-powered reactor can provide 150 kilowatts of electrical power and support a small lunar base for at least 10 years. This would allow NASA astronauts to create oxygen from regolith, provide electricity for other life-support systems, and enable any number of scientific missions. That same system could be scaled up to produce megawatts of electrical power for a large base capable of producing propellant, providing for increasingly larger crews, and enabling ambitious technology demonstrations and groundbreaking science missions.

https://spacenews.com/hubble-returns-to-normal-operations-after-switch-to-backup-computer/

Citar
WASHINGTON — NASA’s Hubble Space Telescope returned to science operations July 17 after a hiatus of more than a month as controllers successfully switched the orbiting observatory to a backup payload computer.

NASA said the instruments of the 31-year-old telescope are now operational nearly five weeks after a payload computer, which commands those instruments, malfunctioned. Those instruments will resume normal science observations after completing calibrations.

After weeks of investigation, engineers concluded that the most likely cause of the payload computer problem was a malfunction of a power control unit, which supplies voltage to the hardware in the computer. With no ability to reset the power control unit from the ground, engineers decided to switch to the backup Science Instrument Command and Data Handling hardware, which has its own power control unit.

According to researchers, other life forms should be ‘out there’, located somewhere at unknown spots among different stars and galaxies. Some of these life forms should have reached similar and even higher level of evolution compared to us, humans. Should we try to contact them? Or should we remain silent?

E pensar que estamos sozinhos, é tão ultrapassado como achar que o Sol órbita à volta da Terra.

Estamos na pré-história da exploração espacial.
A humanidade é como uma tribo isolada numa ilha no meio de uma oceano.
Conseguimos ver o que se passa no horizonte e explorar ilhar vizinhas ignorando e desconhecendo todo um mundo que a rodeia.

Nós somos os Neendertais, as tribos da América do Norte e Sul, e Oceânia.

Só que tal como na expedições por parte dos Europeus, os contactos não correram bem para as tribos.

É melhor estar caladinho pois não sabemos que anda por aí....
