The Airbus-built Solar Orbiter spacecraft has been closed up inside the payload fairing of a United Launch Alliance Atlas 5 rocket in preparation for liftoff from Cape Canaveral in February on a joint mission between the European Space Agency and NASA.
Technicians inside the Astrotech payload processing facility encapsulated the Solar Orbiter spacecraft — designed with thermal shielding to protect against the heat of the sun — inside the Atlas 5’s payload fairing Jan. 20. The spacecraft inside the Atlas 5 rocket’s 4-meter-diameter (13.1-foot) aerodynamic nose shroud will soon travel to ULA’s Vertical Integration Facility, where crane will hoist the payload package atop the launcher.
Valued at nearly $1.7 billion, the Solar Orbiter mission will travel closer to the sun than Mercury, where it will join NASA’s Parker Solar Probe for tandem observations of the solar wind and giant solar eruptions that can affect communications and electrical grids on Earth, plus satellite operations.
To map Earth’s atmosphere, satellite data must be carefully collected, processed, and archived. We cover its journey from outer space to the ground.
NASA is sending a pair of astronauts on a spacewalk outside the International Space Station today (Jan. 25) to finish fixing a complicated science experiment. Here’s how to watch it live.
NASA TV began streaming the spacewalk around 5:30 a.m. EST (1030 GMT) as European Space Agency astronaut Luca Parmitano and NASA astronaut Andrew Morgan complete their final spacewalk preparations. You can watch it live here on Space.com. The spacewalk is expected to start around 6:50 a.m. EST (1150 GMT), when the astronauts will switch their spacesuits over to battery power before heading out of the airlock.
The interior design of the International Space Station takes a back seat to technology—the opposite of the majestic and immaculate spacecraft you see in sci-fi blockbusters.
Oxygen is surprisingly the third most abundant element in the cosmos and likely just as important to life elsewhere as here on Earth. New observations of an oxygen-rich ancient star provide clues to its distribution in the early universe.

Chris Roberts built worlds for games such as Wing Commander at Electronic Arts’ Origin at the dawn of 3D games a couple of decades ago.
Those games were technologically limited, but they still inspired the imagination. Now Roberts is now head of his own company, Roberts Space Industries, and he’s contemplating how to use much more computing power to run the upcoming Star Citizen and other games of the future. He spoke about this challenge with Rich Hilleman, director of PMT at Amazon Game Studios and former chief creative director at EA.
Human skin is a fascinating multifunctional organ with unique properties originating from its flexible and compliant nature. It allows for interfacing with external physical environment through numerous receptors interconnected with the nervous system. Scientists have been trying to transfer these features to artificial skin for a long time, aiming at robotic applications.
Robotic systems heavily rely on electronic and magnetic field sensing functionalities required for positioning and orientation in space. Much research has been devoted to implementation of these functionalities in a flexible, compliant form. Recent advancements in flexible sensors and organic electronics have provided important prerequisites. These devices can operate on soft and elastic surfaces, whereas sensors perceive various physical properties and transmit them via readout circuits.
To closely replicate natural skin, it is necessary to interconnect a large number of individual sensors. This challenging task became a major obstacle in realizing electronic skin. First demonstrations were based on an array of individual sensors addressed separately, which unavoidably resulted in a tremendous number of electronic connections. In order to reduce the necessary wiring, important technology had to be developed—namely, complex electronic circuits, current sources and switches had to be combined with individual magnetic sensors to achieve fully integrated devices.
SAN FRANCISCO, Jan. 21, 2020 /PRNewswire/ — Capella Space, an information services company providing Earth observation data on demand, today unveiled its evolved satellite design to enable on-demand observations of anywhere on Earth.
