The effects of spaceflight on the human body have been studied actively since the mid-20th century. It is widely known that space conditions influence metabolism, thermoregulation, heart biorhythms, muscle tonus, the respiration system and other physiological aspects of the human body function. However, the molecular mechanisms which drive the physiological changes caused by space flights remain unknown.

"The Cassini mission has been packed full of scientific firsts, and our unique planetary revelations will continue to the very end of the mission as Cassini becomes Saturn's first planetary probe, sampling Saturn's atmosphere up until the last second," said Linda Spilker, Cassini project scientist from NASA's Jet Propulsion Laboratory in Pasadena, California. "We'll be sending data in near real time as we rush headlong into the atmosphere — it's truly a first-of-its-kind event at Saturn."

Despite the most powerful technologies we have today, all life forms we know of remain fundamentally limited by their biological hardware. None can live for a million years, memorize all of Wikipedia, understand all known science or enjoy spaceflight without a spacecraft. None can transform our largely lifeless cosmos into a diverse biosphere that will flourish for billions or trillions of years, enabling our universe to finally fulfill its potential and wake up fully. All this requires life to undergo a final upgrade, to Life 3.0, which can design not only its software but also its hardware. In other words, Life 3.0 is the master of its own destiny, finally fully free from its evolutionary shackles.

Isolated in a giant thermal vacuum chamber, NASA’s $8.6 billion next-generation observatory is riding out the worst of Hurricane Harvey, sitting inside a massive, sealed cryogenic chamber at the Johnson Space Center, home of the nation’s astronaut corps and the control center for the International Space Station, JSC is the heart of NASA’s human spaceflight program, a sprawling NASA facility in southeast Houston surrounded by rising floodwaters that some estimates put at 20 trillion gallons.

Models showing what happens to matter just before it is sucked into a black hole may need to be revised after laboratory experiments using the world’s most powerful X-ray machine contradicted one of our best theories performed at Sandia National Laboratories’ Z machine, the most energetic laboratory X-ray source on Earth, can that can duplicate the X-rays surrounding black holes that otherwise can be watched only from a great distance and then theorized about.
