Bioprinted patches could help wounds heal
Researchers successfully demonstrated the function of a handheld bioprinter that could provide a simple and effective way to treat wounds in space using human skin cells. Crews could use this technology to treat their own injuries and protect crew health and mission success in the future.
Spaceflight can affect how wounds heal. The Bioprint FirstAid device tested a process for bioprinting a patch to cover a wound and accelerate healing. In the future, a crew member’s own cells may be used to create personalized patches for treating an injury. The bioprinting device is easy to use, can be tailored to specific needs, has a low failure rate, and its mechanics are electronics- and maintenance-free. This ESA (European Space Agency) investigation was coordinated by the German Aerospace Center (DLR).

The day they return from spaceflight, astronauts demonstrate significant impairments in fine motor control and the ability to multitask in simulated flying and driving challenges. This finding could help develop countermeasures so crew members can safely land and conduct early operations on the Moon and Mars.
Manual Control used a battery of tests to examine how spaceflight affects cognitive, sensory, and motor function after landing. Researchers concluded that subtle physiological changes that occur during spaceflight degrade post-flight performance. Subsequent tests showed recovery of performance once exposed to the task, suggesting that simulation training immediately before a task could be an effective countermeasure. Researchers also suggest limiting dual or competing tasks during mission-critical phases.

Researchers found that the station’s Glowbug gamma-ray telescope could perform in the space radiation environment for multi-year missions. Radiation can affect these types of instruments, but Glowbug regularly detected gamma ray bursts (GRBs) during its one-year operation. Studying GRBs can help scientists better understand the universe and its origins.
Glowbug demonstrated technology to detect and characterize cosmic GRBs, primarily short GRBs, which result from mergers of compact binary star systems containing either two neutron stars or a neutron star and a black hole. Short GRBs produce gravitational waves, ripples in space that travel at the speed of light. Studying these gravitational waves could provide insight into the star systems where they originate and the behavior of matter during the mergers.

What’s Up for November?
When to look for Saturn, Jupiter, and Mars this month, a NASA spacecraft swings by Venus on its way to the Sun, and the tricky business of seeing the Moon hide a bright star. And stick around until the end for photos of highlights from last month’s skies.
Saturn is visible toward the south for most of the night. For observers in the Americas, it has a close meetup with the Moon on the 10th, when the pair will appear less than a degree apart just after dark, making for a great sight through binoculars. Check the sky again around midnight, and you’ll see the Moon has visibly shifted a couple of degrees west of Saturn, showing evidence of the Moon’s orbital motion in just a few hours.
In late 2024, Jupiter could be found high overhead as dawn approached with the bright stars of Taurus and Orion. (Jupiter is the bright object at top, right of center.) NASA/Preston Dyches Jupiter is rising in the east early in the night, together with the bright stars of the constellations Taurus and Orion, and working its way across the sky by dawn. By the end of November, it’s rising just as the sky is getting dark. Mars follows behind Jupiter, rising about three hours after the giant planet.
As in October, early risers will find the Red Planet high overhead in the morning sky before dawn. In the evening sky, Venus is low in the southwest following sunset throughout the month of November. It’s blazing bright and unmistakable if you find a relatively unobstructed view. It appears much higher in the sky for those in the Southern Hemisphere, who’ll also be able to easily observe Mercury after sunset this month. And on the 4th, a slim crescent Moon will appear just below Venus for a beautiful pairing as the glow of sunset fades.
Now, staying with Venus, one of NASA’s intrepid solar system explorers is headed for a close encounter with this Earth-sized hothouse of a planet on November 6th. Parker Solar Probe studies our planet’s nearest star, the Sun. Its mission is to trace the flow of energy that heats the Sun’s outer atmosphere and accelerates the million-mile-per-hour stream of particles it emits. It makes its measurements from super close to the Sun, within the region where all the action happens. To do this, the spacecraft was designed to fly within just 4 million miles of the Sun’s surface, which is 10 times closer than the orbit of the closest planet, Mercury. No other spacecraft has ever gotten this close to the Sun before. In the six years since its launch, the spacecraft has made a bunch of approaches to the Sun, using flybys of the planet Venus to shape its orbit. The November 6th flyby is the final such maneuver, intended to send the spacecraft toward its three closest-ever solar approaches, starting on December 24th. During this last Venus flyby, the mission will capture images of the planet. Previous views returned by Parker showed that the spacecraft could actually see features of the Venusian surface through its dense cloud cover. So look out for Venus in the evening sky, as the brilliant planet helps a craft from Earth to touch the face of the Sun.
In the couple of hours before sunrise on November 27th, skywatchers in the eastern half of the U.S. and Canada will have the chance to witness an occultation – an event where the Moon passes in front of, and temporarily hides, a bright star – in this case Spica. Observers in other parts of the world will see the Moon pass extremely close to Spica, but won’t see it cover up the star. This occultation is one of a series that began in June and will continue monthly through late next year. These happen as the Moon’s orbit slowly shifts northward and southward across the sky, and every so often, its path crosses in front of Spica monthly for a time. But each occultation is only visible from a small portion of Earth. For example, while this November event favors North American viewers, South American observers will get their chance next April. For U.S. skywatchers, this November occultation is the last good opportunity in this series to see the Moon occult Spica until 2032, when a new series of monthly occultations will begin for locations across the globe. Now, if you miss this event, don’t worry!
The Moon also passes in front of three other bright stars from time to time. This means that no matter where you’re located, you’ll have the opportunity before too long to witness the impressive sight of a bright star briefly disappearing behind the Moon.
Watch our video for views of what some of the highlights we told you about in last month’s video actually looked like.

3 Min Read November’s Night Sky Notes: Snowballs from Space
This diagram compares the size of the icy, solid nucleus of comet C/2014 UN271 (Bernardinelli-Bernstein) to several other comets. The majority of comet nuclei observed are smaller than Halley’s comet. They are typically a mile across or less. Comet C/2014 UN271 is currently the record-holder for big comets. And, it may be just the tip of the iceberg. There could be many more monsters out there for astronomers to identify as sky surveys improve in sensitivity. Though astronomers know this comet must be big to be detected so far out to a distance of over 2 billion miles from Earth, only the Hubble Space Telescope has the sharpness and sensitivity to make a definitive estimate of nucleus size.

If you spotted comet C/2023 A3 (Tsuchinshan-ATLAS) in person, or seen photos online this October, you might have been inspired to learn more about these visitors from the outer Solar System. Get ready for the next comet and find out how comets are connected to some of our favorite annual astronomy events.
Comet Composition
A comet is defined as an icy body that is small in size and can develop a ‘tail’ of gas as it approaches the Sun from the outer Solar System. The key traits of a comet are its nucleus, coma, and tail.
The nucleus of the comet is comprised of ice, gas, dust, and rock. This central structure can be up to 80 miles wide in some instances, as recorded by the Hubble Space Telescope in 2022 – large for a comet but too small to see with a telescope. As the comet reaches the inner Solar System, the ice from the nucleus starts to vaporize, converting into gas. The gas cloud that forms around the comet as it approaches the Sun is called the coma. This helps give the comet its glow. But beware: much like Icarus, sometimes these bodies don’t survive their journey around the Sun and can fall apart the closer it gets.
The most prominent feature is the tail of the comet. Under moderately dark skies, the brightest comets show a dust tail, pointed away from the Sun. When photographing comets, you can sometimes resolve the second tail, made of ionized gases that have been electronically charged by solar radiation. These ion tails can appear bluish, in comparison to the white color of the dust tail. The ion tail is also always pointed away from the Sun. In 2007, NASA’s STEREO mission captured images of C/2006 P1 McNaught and its dust tail, stretching over 100 million miles. Studies of those images revealed that solar wind influenced both the ion and dust tail, creating striations – bands – giving both tails a feather appearance in the night sky.

Comets appear from beyond Uranus, in the Kuiper Belt, and may even come from as far as the Oort Cloud. These visitors can be short-period comets like Halley’s Comet, returning every 76 years. This may seem long to us, but long-period comets like Comet Hale-Bopp, observed from 1996-1997 won’t return to the inner Solar System until the year 4385. Other types include non-periodic comets like NEOWISE, which only pass through our Solar System once.
But our experiences of these comets are not limited to the occasional fluffy snowball. As comets orbit the Sun, they can leave a trail of rocky debris in its orbital path. When Earth finds itself passing through one of these debris fields, we experience meteor showers! The most well-known of these is the Perseid meteor shower, caused by Comet 109P/Swift-Tuttle. While this meteor shower happens every August in the northern hemisphere, we won’t see Comet Swift-Tuttle again until the year 2126.
