TEN THOUSAND STARLINKS: SpaceX is on the verge of having 10,000 Starlinks in orbit around Earth. If today's scheduled launch of mission Starlink 10-48 happens as planned, it will add 29 Starlinks to the megaconstellation, pushing the total over 10k. Is this a good thing? You decide. HAPPY PI DAY: March 14th (3.14) is  day, and all around the world pi-philes are celebrating one of the most compelling and mysterious constants of Nature. Pi appears in equations describing the orbits of planets, the colors of auroras, the structure of DNA. The value of is woven into the fabric of life, the universe and ... everything. Humans have struggled to calculate for thousands of years. Divide the circumference of a circle by its diameter; the ratio is . Sounds simple, but the devil is in the digits. While the value of is finite (a smidgen more than 3), the decimal number is infinitely long: 3.1415926535897932384626433832795

HIGH-SPEED SOLAR WIND SPARKS AURORAS: Minor geomagnetic storms are underway on March 14th as a high-speed stream of solar wind wind buffets Earth's magnetic field. Last night, Martin Guth photographed the display from Hermantown, Minnesota:
"The auroras were unexpected and very bright for a while," says Guth. "This is just a 0.6 second exposure."
Flowing from a narrow hole in the sun's atmosphere, the solar wind is blowing almost 700 km/s (1.6 millon mph). High-latitude auroras should persist as long as Earth remains inside the stream--perhaps another 12 to 24 hours. Aurora alerts: SMS Text

"I NEED MY SPACE" SNOOPY CUP: Coffee tastes better in a cup that's been to space. On July 16th, the students of Earth to Sky Calculus launched this Snoopy cup to the stratosphere onboard a cosmic ray research balloon. Here it is floating more than 105,315 feet above Earth's surface:
You can have it for $119.95. It's Peanuts for a cup from space! The students are selling Snoopy cups to support their cosmic ray monitoring program. Each one comes with a greeting card showing the cup in flight and telling the story of its trip to the stratosphere and back again.
Every item in the Earth to Sky Store has been to the edge of space--floating above 99.7% of Earth's atmosphere, experiencing space-like blasts of cosmic rays, extreme cold, and a wild ride parachuting back to Earth. Even Amazon doesn't carry items this far out. And, best of all, all sales support student science projects and STEM education.

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 March 13, 2026, the network reported 4 fireballs.
(4 sporadics)
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).

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 March 14, 2026 there were 2349 potentially hazardous asteroids.

Cosmic Rays in the Atmosphere |
SPACE WEATHER BALLOON DATA: Almost once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. 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 10 years, resulting in a unique dataset of in situ atmospheric measurements.
Latest results (Nov. 2024): Atmospheric radiation is sharply decreasing in 2024. Our latest measurements in November registered a 10-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.
