A TINY SPACECRAFT IN DEEP SPACE: This week, NASA's Orion spacecraft reached its farthest distance from Earth -- 268,563 miles away. That's farther than any other human-rated spacecraft in the history of the Space Age. Astronomer Gianluca Masi of Ceccano, Italy, photographed Orion approaching the farpoint: 
"Taking such a picture was quite difficult," says Masi . "The spacecraft is only 5 meters in diameter, and at this extreme distance it was fainter than a 16th magnitude star. I managed to capture Orion using the Virtual Telescope Project's robotic facility in Italy. The telescope tracked Orion's apparent motion, this is why stars look like long trails while the probe is a sharp dot of light." While Masi was photographing Orion, Orion was photographing Masi. This is what the spacecraft saw looking back at Earth: 
As seen from Orion, Earth and the Moon had nearly identical gibbous phases. We've all seen a gibbous Moon, but the one Orion saw was different. The daylit landscape was all farside--the side of the Moon invisible from Earth. Orion was more than 40,000 miles above the Moon's farside at the time of the snapshot. Orion is now halfway through its 25.5 day mission to the Moon. NASA says the spacecraft remains in healthy condition as it continues its journey in distant retrograde lunar orbit. Orion is set to return to Earth on Dec. 11th with a record-hot reentry and a splashdown in the Pacific Ocean. Check NASA's Artemis blog for updates. Realtime Space Weather Photo Gallery

On Nov. 25th, it flew to the stratosphere onboard an Earth to Sky Calculus cosmic ray research balloon. At the apex of the flight (117,109 ft), the temperature was a frosty -63C: 
You can have it for $99.95. This double-walled whiskey glass is cast from one of the original molds for Storm Trooper helmets used in Star Wars: A New Hope in 1977. Made of high quality borosilicate, the glass is thin, hard and lead-free. It makes a great Christmas gift for Star Wars fans. The glass comes with a greeting card showing the item in flight, and telling the story of its journey to the stratosphere and back again. Far Out Gifts: Earth to Sky Store

Free: Spaceweather.com Newsletter Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com. On Nov 30, 2022, the network reported 20 fireballs.
(19 sporadics, 1 Nov. omega Orionid)  In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies] Potentially Hazardous Asteroids ( PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time. On November 30, 2022 there were 2316 potentially hazardous asteroids.

These balloons are equipped with sensors that detect secondary cosmic rays, a form of radiation from space that can penetrate all the way down to Earth's surface. Our monitoring program has been underway without interruption for 7 years, resulting in a unique dataset of in situ atmospheric measurements. Latest results (July 2022): Atmospheric radiation is decreasing in 2022. Our latest measurements in July 2022 registered a 6-year low: 
What's going on? Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 has roared to life faster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside cosmic rays, causing sharp reductions called "Forbush Decreases." The two effects blend together to bring daily radiation levels down. .Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can alter the chemistry of the atmosphere, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. A number of controversial studies (#1, #2, #3, #4) go even further, linking cosmic rays with cardiac arrhythmias and sudden cardiac death. Technical notes: The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners. Data points in the graph labeled "Stratospheric Radiation" correspond to the peak of the Regener-Pfotzer maximum, which lies about 67,000 feet above central California. When cosmic rays crash into Earth's atmosphere, they produce a spray of secondary particles that is most intense at the entrance to the stratosphere. Physicists Eric Regener and Georg Pfotzer discovered the maximum using balloons in the 1930s and it is what we are measuring today. | | The official U.S. government space weather bureau | | | The first place to look for information about sundogs, pillars, rainbows and related phenomena. | | | Researchers call it a "Hubble for the sun."
