NASA dixit:
“This week we’ll see the 53rd set of crew members return to Earth from the International Space Station, but we’ll only “see” it from the outside. What will the astronauts and cosmonauts see as they depart their home in space and return to the planet from whence they came? If you’ve got 60 seconds to spare, here’s the insider’s view of what a return to Earth on a Soyuz spacecraft looks like to the people on board.”

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.”

NASA dixit:
“NASA’s Parker Solar Probe is in the midst of intense environmental testing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in preparation for its journey to the Sun. These tests simulate the noise and shaking the spacecraft will experience during its launch from Cape Canaveral, Florida, scheduled for 2018.
Parker Solar Probe’s integration and testing team must check over the spacecraft and systems to make sure everything is still in optimal working condition after experiencing these rigorous conditions – including a check of the solar arrays, which will provide electrical power to the spacecraft.
Parker Solar Probe will explore the Sun’s outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also help improve how we forecast major eruptions on the Sun and subsequent space weather events that can impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have helped shape the field of heliophysics.”
