NASA dixit:
“The SpaceX CRS-13 mission begins with an on-time liftoff of the company’s Falcon 9 rocket and Dragon spacecraft from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Launch occurred on December 15 at 10:36 a.m. EST. The Dragon is carrying equipment, science and supplies to the International Space Station on SpaceX’s 13th commercial cargo resupply mission.”

NASA dixit:
“Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler space telescope.
The newly-discovered Kepler-90i — a sizzling hot, rocky planet that orbits its star once every 14.4 days — was found by researchers from Google and The University of Texas at Austin using machine learning. Machine learning is an approach to artificial intelligence in which computers “learn.” In this case, computers learned to identify planets by finding in Kepler data instances where the telescope recorded signals from planets beyond our solar system, known as exoplanets.”

Europe’s Galileo satellite navigation system performed a giant leap nearer completion on Tuesday 12 December, as four more Galileo satellites were launched into orbit by Ariane 5.
Liftoff from Europe’s Spaceport in Kourou, French Guiana took place at 18:36 UTC (19:36 CET, 15:36 local time), carrying Galileo satellites 19–22. Separation of the upper stage occurred about nine minutes after liftoff, followed by the first firing of the upper stage. The upper stage – carrying four 715-kg Galileo satellites – flew in ballistic configuration for three hours and eight minutes, after which a second upper stage firing placed it into circular separation orbit. Once stabilised at 3h 35 min after liftoff, the Galileo dispenser released the first two satellites, followed by the second pair 20 minutes later.
At orbital injection the launcher attained an altitude of 22 925 km, approximately 300 km below the Galileo satellites’ operational altitude. The four satellites manoeuvred themselves up to this height, leaving the passivated upper stage safely in a ‘graveyard orbit’.

Planetary Resources dixit:
“The Arkyd-6 spacecraft not only tests our core technologies, but also tests how we work together as a team. In this video, our Director of Systems Engineering Brian Douglas describes the design and engineering philosophies that worked really well for us when building Arkyd-6.
Using components that were not originally designed for space, innovating where it makes sense, and having a single owner from a hardware’s inception to its operation are some philosophies that we will continue to build upon as we design the Arkyd-301 spacecraft. ​”

“Peer over the shoulders of our engineers as they build hardware for NASA’s Mars 2020 mission. This 360 video transports you to the historic Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Pasadena, California. Engineer Emily Howard narrates as you walk around the cruise stage, which will fly the 2020 rover to the Red Planet, and the descent stage, which will lower the rover to the Martian surface.”

NASA dixit:
“In just a couple of years, NASA’s newest rover will be flying to Mars. The Mars 2020 mission will use the next generation of science and landing technology to collect rock samples for possible return by a future mission.”
