SpaceX has finally landed its Falcon 9 rocket on a drone ship at sea, after launching the vehicle into space this afternoon.
It's the first time the company has been able to pull off an ocean landing, after four previous attempts ended in failure. Today's success is a crucial milestone for SpaceX, as it shows the company can land its rockets both on solid ground and at sea. Andromeda Galaxy. Solar System 2.0 - the helical model.

Extra-Tropical Alex Speeding Through North Atlantic Tropical Storm Alex quickly acquired extra-tropical characteristics late on Jan. 15 as it sped northward toward Greenland in the North Atlantic Ocean.

During a week of revelations about the strange worlds at the edge of the solar system, I repeatedly heard a question that often comes up about space: "why bother?
" It's a fair challenge. What is the point of spending taxpayers' money on a venture to Pluto or some other frigid corner of the cosmos? Or having some of our greatest brains devoted to studying alien rock and ice when they could be working on problems much closer to home? And nobody should duck the question. So here goes: should journalists like me, along with camera crews, even cover an event like the New Horizons mission? This was first brought home to me during the European Space Agency's dramatic touchdown on a comet last November. Philae comet lander wakes up - BBC News. The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.
Philae was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November. It worked for 60 hours before going to sleep when its solar-powered battery ran flat.

And so, living in space, the oddness never quite goes away. Consider something as elemental as sleep. Nasa just emailed a wrench to space. When International Space Station commander Barry Wilmore needed a wrench, Nasa knew just what to do.
They "emailed" him one. This is the first time an object has been designed on Earth and then transmitted to space for manufacture. Made In Space, the California company that designed the 3D printer aboard the ISS, overheard Wilmore mentioning the need for a ratcheting socket wrench and decided to create one. Previously, if an astronaut needed a specific tool it would have to be flown up on the next mission to the ISS, which could take months. BBC iWonder - What makes space travel so dangerous? Code and Life: Philae: The Biggest Jump Ever. So, Philae bounced twice before coming to a halt. 'Bounce' does not quite describe it correctly.
Philae did by far the biggest #jump ever. The f*cking tallest, longest, slowest JUMP ever done by a human made object (including humans). Without using thrusters, just by pushing off from a rock. That's something for the Guiness Book of Records. And Philae was lucky as hell. Lucky Philae. Rethinking the origins of the universe. Singled out: Laura Mersini-Houghton has mathematically proven that quantum effects are strong enough to stop the formation of black holes, work that opens up a new round of discussions and debates about the origins of the universe.
Black holes have long captured the public imagination and been the subject of popular culture, from Star Trek to Hollywood. Aeronautics e-Book Archive. NASA Confirms the "Impossible" - Propellant-free Microwave Thruster for Spacecraft Works! Designs for a device called a microwave thruster, which could power spacecraft without the need for propellant, have been proposed since 2006. While the engine follows the principles of relativity theory in converting electrical energy into force to produce thrust, it has been dismissed as impossible in practice since it defies the law of conservation of momentum. But a team from NASA has just successfully trialled their own version of the engine, which changes everything. Several years ago British scientist Roger Shawyer presented his EmDrive microwave thruster engine to the scientific community. It used microwaves bounced off reflectors in a sealed container to produce small amounts of force and thereby achieve propulsion via propellant-free thrust.
Its possibilities for long-distance spaceflight were extraordinary, but while it was groundbreaking there was one catch: it defied the law of conservation of momentum and was therefore deemed theoretically flawed. . + EmDrive. Sea plankton have been found on the International Space Station – but how did they get there? Sea plankton have been found on the outside of the International Space Station, a Russian news agency reports.
Itar-Tass says scientists on the space station, whose first component was launched into orbit in 1998, found the plankton – a source of food to many sea creatures – when taking samples from the windows (or “illuminators”). This, the agency writes, confirms “that some organisms can live on the surface of the International Space Station (ISS) for years amid factors of a space flight, such as zero gravity, temperature conditions and hard cosmic radiation. Several surveys proved that these organisms can even develop.” Stuff website reported that the plankton samples “were not carried there at launch, but are thought to have been blown over by air currents on Earth”.
Do We Live in the Matrix? They could create a plethora of pet universes, vastly outnumbering the real cosmos. This thought led philosopher Nick Bostrom at the University of Oxford to conclude in 2003 that it makes more sense to bet that we’re delusional silicon-based artificial intelligences in one of these many forgeries, rather than carbon-based organisms in the genuine universe. Since there seemed no way to tell the difference between the two possibilities, however, bookmakers did not have to lose sleep working out the precise odds.
Learning the Truth That changed in 2007 when John D. Barrow, professor of mathematical sciences at Cambridge University, suggested that an imperfect simulation of reality would contain detectable glitches.

Study finds astronauts' hearts become more spherical in space. 29-Mar-2014 [ Print | E-mail ] Share [ Close Window ] Contact: Beth Casteelbcasteel@acc.org 202-375-6275American College of Cardiology New findings from a study of 12 astronauts show the heart becomes more spherical when exposed to long periods of microgravity in space, a change that could lead to cardiac problems, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session. With implications for an eventual manned mission to Mars, the findings represent an important step toward understanding how a spaceflight of 18 months or more could affect astronauts' heart health.
"The heart doesn't work as hard in space, which can cause a loss of muscle mass," said James Thomas, M.D., Moore Chair of Cardiovascular Imaging and Lead Scientist for Ultrasound at NASA, and senior author of the study.
