This week’s image shows a Soyuz rocket sending a crew to the International Space Station (ISS) on Thanksgiving Day. One NASA astronaut and two Russian cosmonauts are thankful today that they are safe and sound on the ISS. NASA astronaut Chris Williams joined Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev aboard a Soyuz rocket launched from Russia earlier today.

The three crew members of Expedition 74 join the Expedition 73 crew members already on the station, increasing the crew count to 10 members for the next few weeks. Expedition 74 is scheduled to begin on Monday, December 8th, once three members depart the ISS.

These crews change like clockwork, regardless of holidays, government shutdowns, or even hot wars back on the surface. This dedication to duty is something we can all be thankful for.

Pic of the Week: Wolf-Rayet Apep

This week’s embryonic image comes from the James Webb Space Telescope (JWST). It shows what NASA calls “four serpentine spirals of dust” around a pair of Wolf-Rayet stars. Such stars are rare, with NASA estimating that only a thousand can be found in our galaxy consisting of hundreds of billions of stars. And binary Wolf-Rayet stars are even rarer.

NASA notes that the JWST, or Webb, provided a much better image of the spiraling dust:

Observations taken prior to Webb only detected one shell, and while the existence of outer shells was hypothesized, searches using ground-based telescopes were unable to uncover any. These shells were emitted over the last 700 years by two aging Wolf-Rayet stars in a system known as Apep, a nod to the Egyptian god of chaos...Webb also confirmed that there are three stars gravitationally bound to one another in this system. The dust ejected by the two Wolf-Rayet stars is “slashed” by a third star, a massive supergiant, which carves holes into each expanding cloud of dust from its wider orbit. (All three stars are shown as a single bright point of light in Webb’s image.)

Pic of the Week: The New Glenn Rocket Booster Returns

Today’s image comes from Blue Origin, which successfully completed it second launch of it New Glenn rockets, sending two NASA Martian probes into orbit. The image shows the reusable rocket booster right after it landed on a platform in the Atlantic Ocean.

Acting NASA Administrator Sean Duffy stated:

Congratulations to Blue Origin, Rocket Lab, UC Berkeley, and all of our partners on the successful launch of ESCAPADE…This heliophysics mission will help reveal how Mars became a desert planet, and how solar eruptions affect the Martian surface. Every launch of New Glenn provides data that will be essential when we launch MK-1 through Artemis. All of this information will be critical to protect future NASA explorers and invaluable as we evaluate how to deliver on President Trump’s vision of planting the Stars and Stripes on Mars.

SpaceX now has another competitor for military and space missions, which is good for everyone (including SpaceX since it will keep them focused).

Pic of the Week: Pismis 24

This week’s amazingly vibrant image was captured by the James Webb Space Telescope (JWST). It shows a young star cluster, called Pismis 24, which is approximately 5,500 light-years away.

Here is the rest of the story from the European Space Agency (ESA):

What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. This region is one of the best places to explore the properties of hot young stars and how they evolve.

Pic of the Week: Dead Comet From Halloween Past

This spooky image of a dead comet was captured 10 years ago, but it still serves this purpose this time of year. It passed the Earth on Halloween evening that year at a distance of about 302,000 miles.

Here is more from NASA’s Jet Propulsion Laboratory:

Scientists observing asteroid 2015 TB145 with NASA’s Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii, have determined that the celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun.

The belated comet has also been observed by optical and radar observatories around the world, providing even more data, including our first close-up views of its surface…

The first radar images of the dead comet were generated by the National Science Foundation’s 305-meter (1,000-foot) Arecibo Observatory in Puerto Rico. The radar images from Arecibo indicate the object is spherical in shape and approximately 2,000 feet (600 meters) in diameter and completes a rotation about once every five hours.

“The IRTF data may indicate that the object might be a dead comet, but in the Arecibo images it appears to have donned a skull costume for its Halloween flyby,” said Kelly Fast, IRTF program scientist at NASA Headquarters and acting program manager for NASA’s NEO Observations Program.
