When astronauts left the International Space Station in early November to return home on the Crew Dragon Endeavour, they took the opportunity to do a fly-around of the ISS and take photos. NASA just released the new images, and they are a stunning look at both the orbiting outpost and our home planet.

The person behind the camera was ESA astronaut Thomas Pesquet. He began taking photos after Crew Dragon undocked from the Harmony module. Also on board were NASA astronauts Shane Kimbrough and Megan McArthur, and JAXA astronaut Aki Hoshide. They had spent six months aboard the ISS.

“Bittersweet feeling about leaving the ISS,” Pesquet tweeted. “When you think about it, it’s really a magical place, almost impossible to reach and which gives you superpowers like flying, or going around the world in 1h30 … It still looks a bit like a daydream.”

There is a huge global effort to engineer a computer capable of harnessing the power of quantum physics to carry out computations of unprecedented complexity. While formidable technological obstacles still stand in the way of creating such a quantum computer, today’s early prototypes are still capable of remarkable feats.

For example, the creation of a new phase of matter called a “time crystal.” Just as a crystal’s structure repeats in space, a time crystal repeats in time and, importantly, does so infinitely and without any further input of energy—like a clock that runs forever without any batteries. The quest to realize this phase of matter has been a longstanding challenge in theory and experiment—one that has now finally come to fruition.

In research published Nov. 30 in Nature, a team of scientists from Stanford University, Google Quantum AI, the Max Planck Institute for Physics of Complex Systems and Oxford University detail their creation of a time crystal using Google’s Sycamore quantum computing hardware.

WASHINGTON — NASA postponed a spacewalk outside the International Space Station by two astronauts just hours before it was scheduled to start after getting a warning that debris would pass close to the station.

In a brief statement issued early Nov. 30, NASA said a “debris notification” it received on the evening of Nov. 29 led the agency to postpone the spacewalk by astronauts Tom Marshburn and Kayla Barron, which had been scheduled to start at about 7:10 a.m. Eastern. The two had planned to replace an S-band antenna on the station’s truss that recently lost the ability to transmit data.

“Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the spacewalk until more information is available,” NASA said in the statement. The agency did not identify the debris in question or the times and distances of closest approach to the station.

On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks.

The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.

One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.

NASA’s Parker Solar Probe has set a new pair of records after it survived its 10th close encounter with the Sun. On November 21, 2021 at 4:25 am EST (08:25 GMT), the robotic deep-space explorer came within 5.3 million miles (8.5 million km) of the Sun’s surface and reached a speed of 363,660 mph (586,864 km/h), making it both the closest satellite to survive such a near pass of the Sun and the fastest-ever artificial object.

The Parker Solar Probe was launched on August 12, 2018 from Cape Canaveral Air Force Station atop a Delta IV Heavy rocket, and this latest solar flyby between November 16 and 26 marks the halfway point in the spacecraft’s seven-year mission to study the Sun at such close quarters that it will eventually fly through the Sun’s corona.

Having easily beaten the record holder, the Helios-2 spacecraft and its maximum speed of 157,078 mph (252,792 km/h), Parker is now in a league of its own. Its latest speed record beats its own previous record, as will be the case for the future record speeds the probe is expected to reach in later flybys.

The holidays still happen in space, they just look a little bit different. But the sentiments are the same.

“I’m going to do whatever I can to show how thankful I am for my crewmates,” said NASA astronaut Mark Vande Hei in a NASA video shared from the International Space Station Monday. “It’s wonderful having all of these folks up here. We haven’t been up here together that long, but wow it sure has been wonderful already.”

The space station will host seven crew members throughout the holiday season.

F4F is launching Blue Marble Night as a new spacer holiday, commemorating the Blue Marble photo taken by Apollo 17 on 7 December, 1972.
Want to help?

We are setting up a celebration of the limitless inspiration of space. One that recognizes the fragility of our world while simultaneously infusing a sense of hope and awe. We will have the Overview Effect and our future in space as the main focuses. :
Here is what you can do:

1. Recruit celebrities and regular people to record 30–60 second testimonials about the Overview Effect or their connection to space.

2. Recruit thought leaders willing to give 10–15 minute talks about the majesty of space, the Overview Effect, our future in space, Apollo 17 etc.

(In both vids, close out the vid with the toast “Happy Blue Marble Night and next year on the moon.” Encourage people to wear blue or to toast with blue drinks.

3. Make art centred on the Blue Marble photo, the Overview Effect or our future in space and post it to your social media accounts and tag @f4fspace and include the hashtag #BlueMarbleNight.

As a bonus:
