A large chunk of debris from a SpaceX rocket has been found floating off a remote British island, more than 4,000 miles (6,500 kilometers) from where it exploded after takeoff. The barnacle-encrusted debris - which measures about 33 feet by 13 feet (10 meters by 4 meters) and is decorated with a U.S. flag - is believed to have come from an unmanned Falcon 9 rocket, designed by Elon Musk's private aerospace company.

A U.S. National Oceanic and Atmospheric Administration (NOAA) satellite retired in 2014 has suffered an apparent breakup, the second time in less than a year that a polar-orbiting weather satellite has generated orbital debris. The Joint Space Operations Center (JSpOC) announced Nov. 25 that it had identified a possible breakup of the NOAA 16 satellite. The center, which tracks objects in orbit and warns of potential collisions, said it first detected the breakup at 3:41 a.m. Eastern time and was tracking an unspecified number of “associated objects” in the orbit of NOAA 16.

China on Thursday, Nov. 26, conducted another surprise launch this year, lifting the Yaogan-29 satellite into space. The spacecraft was launched atop a Long March 4C booster at 5:24 p.m. EDT (21:24 GMT) from the LC9 launch complex at the Taiyuan Satellite Launch Center (TSLC), located in Shanxi Province, north China.
Following months of intensive training, mission controllers for the LISA Pathfinder gravitational wave detection testbed will complete a final rehearsal tomorrow, ensuring that all is ready for the journey to space. Next week, a Vega rocket will lift LISA Pathfinder into space on a mission that will test-drive the hardware for detecting gravitational waves – ripples in spacetime, the very fabric of the Universe.
All four laser guide star units that form the Four Laser Guide Star Facility — a core part of the Adaptive Optics Facility (AOF) for ESO’s Very Large Telescope — have now been accepted and are being shipped to Chile. This is a major step towards establishing VLT Unit Telescope 4 as a fully adaptive telescope with much enhanced image quality.

An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a black hole swallowing a star and ejecting a flare of matter moving at nearly the speed of light. The finding reported Thursday in the journal Science tracks the star — about the size of our sun — as it shifts from its customary path, slips into the gravitational pull of a supermassive black hole and is sucked in, said Sjoert van Velzen, a Hubble fellow at Johns Hopkins.
Space Systems Loral (SSL), a leading provider of commercial satellites, announced that it has been selected to build a powerful, high throughput communications satellite for Telesat, one of the world’s top satellite operators. The new spacecraft, called Telstar 19 VANTAGE, will have two high throughput payloads, one in Ku-band and the other in Ka-band, to serve growing markets in Latin America, the North Atlantic Ocean, the Caribbean and Northern Canada.
