TODAY IN HISTORY: On October 18, 1989, The Galileo Space Probe Launched From Cape Canaveral, Florida

Inmarsat-5 F4 successfully launched from LC-39A at Kennedy Space Center at 7:21pm EDT May 15. The Falcon 9 deployed the satellite into Geostationary Transfer Orbit 31 minutes and 48 seconds after liftoff.  Since the rocket was flying in its expandable configuration, following main engine cutoff the first stage fell into the Atlantic ocean and was not recovered.  The launch of the Inmarsat mission marked the first time SpaceX began testing countdown procedures for their next major upgrade of the Falcon 9 rocket, the Block IV. Normally, the rocket’s liquid oxygen propellant is loaded into the rocket 45 minutes before launch, ten minutes after RP-1.  For Inmarsat, the LOX was loaded 35 minutes before liftoff. The Block IV variant will see this procedure occur during every countdown. Check out or Inmarsat-5 F4 launch archive here.

Andromeda (M31) e Triangolo (M33), le due galassie giganti più vicine alla nostra Via Lattea. Queste, insieme ad una trentina di più "piccole" fanno parte del Gruppo Locale (si stima che il suo diametro sia di 4 milioni di anni luce!)

In July 1967, astronomers at the Cavendish Laboratory in Cambridge, observed an unidentified radio signal from interstellar space, which flashed periodically every 1.33730 seconds. This object flashed with such regularity that it was accurate enough to be used as a clock and only be off by one part in a hundred million.

It was eventually determined that this was the first discovery of a pulsar, CP-1919.  This is an object that has about the same mass as the Sun, but is the size of the San Francisco Bay at its widest (~20 kilometers) that is rotating so fast that its emitting a beam of light towards Earth like a strobing light house! Pulsars are neutron stars that are formed from the remnants of a massive star when it experiences stellar death.

A hand drawn graph plotted in the style of a waterfall plot, in the Cambridge Encyclopedia of Astronomy, later became renown for its use on the cover of the album “Unknown Pleasures”  by 1970s English band Joy Division.

Some even managed to point out the resemblance of this plot to some other waterfall plot gifs.

Also, two days ago today was Joy Divisions singer’s, Ian Curtis, birthday!

We’re studying a new method of water recycling and carbon dioxide removal that relies on specific geometric shapes and fluid dynamics, rather than complex machinery, in an effort to help build better life support systems for spacecraft. The research could also teach us more about the water processing approaches we take on Earth. Here, NASA astronaut Jack Fischer, is working with the Capillary Structures for Exploration Life Support (Capillary Structures) investigation capillary sorbent hardware that is made up of 3D printed contractors that are supported by tubing, valves and a pump.

Learn more about how this highly interactive investigation works, and what we could learn from the results HERE.
