This is what our night sky could look like guys.

T-51 days (October 14) - OA-4 Cygnus service module arrives at KSC Marking a major milestone in its prelaunch processing flow, the service module for the Cygnus spacecraft’s return to flight arrived at Kennedy Space Center earlier this week. The pressurized cargo module for the OA-4 mission arrived at Kennedy in early August, and technicians have been checking out the module ahead of cargo stowing. OA-4 marks a significant shift in the Cygnus program, not just because it is the spacecraft’s return to flight, but also the first flight of the Enhanced Cygnus. The cargo module is 3.9 feet longer than the initial Standard Cygnus, allowing the spacecraft to transport over 3,300 extra pounds of cargo. The Service Module also boasts new Orbital ATK-made Ultraflex solar arrays, which are lighter than the original rectangular arrays made by DutchSpace. The image below shows a comparison between the two versions of the spacecraft, with the Enhanced Cygnus on the right.
Final assembly and cargo stowage is expected to occur in late October and early November. Encapsulation inside an Atlas V 400-series payload fairing will occur in mid November, followed by rollout to SLC-41 and vehicle integration in late November. Currently, the launch of OA-4 is scheduled for December 3, though that date may move up or be pushed back depending on various factors. It will be the first flight of the spacecraft since an October 29, 2014 launch failure that destroyed the spacecraft and subsequently grounded the program. The enhanced Antares 200 rocket is undergoing final integration and assembly at Wallops Island, Virginia, and Orbital ATK teams are preparing for a period of pad testing. The next flight of Cygnus on an Antares is scheduled for some time in the first half of 2016. Until then, Orbital ATK purchased two Atlas V 401 rockets to launch their enhanced Cygnus spacecraft; these missions are designated OA-4 and OA-5. The second flight is slated for sometime in spring of 2016.
NASA just released a brand new equirectangular projection of Jupiter, so I thought it would be fun to revisit the surface of some planetary bodies … IN CONTINUOUSLY LOOPING GIF FORM.

A supernova will appear in the sky in the first few months of 2016, according to astronomers working on the Hubble Space Telescope. The prediction is possible because they first saw the star explode in 2014 in a gravitationally lensed galaxy, which will make it visible again next year.
Gravitational lenses happen when a massive object (or objects such as a cluster of galaxies) magnifies and distorts the light of background galaxies. In this case, the galaxy cluster is so massive that it deforms space and time so that it acts like a gigantic magnifying glass.
Sometimes, these distortions produce multiple images of the same object. Although they belong to the same galaxy, the images we see were not emitted at the same time. Because light travels at a finite speed, photons will take a different amount of time to travel around the massive object depending on the path they follow – with some routes taking longer than others.
The supernova explosion that we will see in 2016 is a re-run of the 2014 one, known as the Refsdal Supernova. It was generated in a galaxy nine billion light-years away, and the lens is created by a massive galaxy cluster, called MACS J1149+2223, five billion light-years from us.

launched eighteen years ago, the cassini orbiter is set to crash in to saturn next september, ending its mission to collect data, including these true colour images, on saturn and it’s moons and rings. saturn’s main rings, composed mostly of ice, are thought to have formed only a few hundred million years ago, long after the planet, and the solar system itself, were birthed some four and half billion years ago.
though a hundred and seventy million miles in diameter, the main rings are only half a mile thick, with the brighter bands showing areas of greater density, and the darker, less dense areas swept relatively clear by the gravity of saturns’ moons - clear enough, anyways, for the cassini orbiter to pass through one of the gaps basically unscathed.
there is no consensus on how the rings were created, but a medium sized moon, either shattered by a meteor or pulled apart by the planet’s gravity, would account for the entire mass of the rings. there is, however, more of a consensus that in about fifty million years, saturn’s gravity will have pulled in the rings and swallowed them up. (but at least mars should have a ring by then.)
saturn has over forty moons, including one found within a ring gap. these photos show the distant rhea and titan - the latter of which is larger than mercury and has its own atmosphere and hydrocarbon lake - and the inner most mimas and enceladus - the latter being notable for its encompassing liquid ocean of water and geothermal activity.

mark your calendars!!!
The first structural test article of Orion’s Service Module arrived at NASA’s Glenn Research Center in Cleveland, Ohio yesterday (November 9). Manufactured by Airbus Defense and Space in Europe, (the same company who built the Automated Transfer Vehicle), the European Service Module will provide Orion’s electrical, propulsion and umbilical capabilities during flight. A single Orbital Maneuvering System engine leftover from the Space Shuttle program will power the spacecraft, and four 11-kilowatt solar panels will generate electrical power. The STA will be used for fit checks and other engineering tests at NASA’s Plumb Brook facility, which is a sub-facility of Glenn. An Antonov-124 aircraft, the second largest cargo plane in the world delivered the ESM STA to Cleveland International Airport November 9.
