Virgin Galactic's SpaceShipTwo, VSS Unity, flew higher than it ever has before on Thursday, surpassing what the US Air Force considers the boundary of space, and marking the first manned flight to space from US soil since 2011. He called yesterday "a momentous day and I could not be more proud of our teams who together have opened a new chapter of space exploration". We've had tears, real tears, and moments of joy.

Geminid meteor shower: Where, when and how to see it Geminid meteor shower: Where, when and how to see it
- December 15, 2018

Every year, Earth passes through a cloud of debris from an asteroid named 3200 Phaethon . When the atmosphere hits them, the dust particles briefly energize and switch from what astronomers call meteoroids into meteors . NASA astronomer Bill Cooke told USA Today that the Geminids used to peak at just 30 meteors per hour, but Jupiter's gravity has brought the shower closer to our planet, increasing the rate of shooting stars.

But nowadays, almost 120 meteors can be seen across the sky at the peak. Find a dark location away from artificial light with a view of as much of the sky as possible; websites like Dark Sky Finder can help you find good spots. "But astronomers have determined that the source for the Geminids is this weird object 3200 Phaethon , which seems to have characteristics of both an asteroid and a dead (mostly dust-less) comet".

Russian cosmonauts take sample of mystery hole at space station Russian cosmonauts take sample of mystery hole at space station
- December 14, 2018

Crew members used tape to cover the hole and experts speculated that it could have been caused by the impact of a high-speed rocky fragment flying through space. So far astronauts have only been able to examine the hole from inside the spacecraft. That section of the capsule will be jettisoned as usual before re-entry, and so poses no risk for descent.

Then at 43,000 feet - more than 8 miles high - its pilots commanded the plane's release and switched on VSS Unity's rocket engine to drive the vehicle directly upward at supersonic speeds. The test demonstrates significant progress toward the start of commercial flights that were promised more than a decade ago. More than 600 people have paid or put down deposits to fly aboard Virgin's suborbital missions, including actor Leonardo DiCaprio and pop star Justin Bieber. (more...)

This is the Geminid meteor shower , so named because the meteors appear to come from a radiant in the constellation Gemini. "I've often said they resemble "celestial field mice" as they scurry across the sky, producing good numbers of bright, graceful, yellowish-white meteors and fireballs ", wrote Joe Rao of Space.com.

At this distance, it will be a mere 7.1 million miles away from Earth, which is close is astronomical terms. There is a zero per cent chance of the comet hitting Earth, according to astronomers at the University of Maryland, though it could remain visible in the night sky for several weeks after its December 16 peak.

Spacewalking astronauts check site of capsule leak
- December 12, 2018

Russian cosmonauts Oleg Kononenko and Sergey Prokopyev weren't locked out and trying to get back in, they were looking for remnants of a hole that caused a leak in the capsule back in August . This part of the capsule will be jettisoned as usual before atmospheric re-entry, and so poses no risk for descent. The samples, data and photographs taken from the leak site will be brought back to Earth and analyzed by Russian specialists. (more...)

Voyager 2 is over 11 billion miles from the Sun, travelling at 55,025km per hour away from its creators. Voyager 1 crossed the boundary of the heliosphere, a transition zone known as the heliopause , in 2012. Other instruments on the spacecraft have provided evidence consistent with having crossed past the heliopause and into interstellar space. The instrument has not detected any signs of the solar wind since then. (more...)

Tidal forces on Earth slow the moon's rotation to the point where the same side always faces Earth. Scientists have speculated about a number of uses for the far side of the moon , including setting up radio telescopes. The sunlight there can ensure the probe's energy supply. The rover is expected to land around the New Year to carry out experiments and explore the untrodden terrain. (more...)

SpaceX engineers were less happy with the first-stage booster which dropped into the Atlantic Ocean off the Florida coast, missing its designated landing zone on ground. Over 5,600 pounds of supplies, experiments, and equipment will arrive in a few days. And the Dragon brings a special treat for one class of spacecraft: It's carrying a satellite deployment system called SlingShot that can fit inside the Cygnus spacecraft's berth to deploy up to 18 cubesats.
