T-51 Days (October 14) - OA-4 Cygnus Service Module Arrives At KSC Marking A Major Milestone In Its Prelaunch

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.

The large space rock that will zip past Earth this Halloween is most likely a dead comet that, fittingly, bears an eerie resemblance to a skull.

These first radar images from the National Science Foundation’s 1,000-foot (305-meter) Arecibo Observatory in Puerto Rico, indicate the near-Earth object is spherical in shape and approximately 2,000 feet (600 meters) in diameter. The radar images were taken on Oct. 30, 2015.

Scientists observing asteroid 2015 TB145 with NASA’s Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii, have determined that the celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun.

We are not allowed to collect water from Mars. The Outer Space Treaty of 1967 forbids every nation in the world from sending humans or robots near celestial water sources for fear of contaminating them with life from Earth. Source
