Study Notes

November Supermoon

November 15, 2024, will be the last supermoon of 2024.
It follows a series of supermoons: August's Blue Moon, September's Harvest Moon, and October's Hunter Moon.
Supermoons appear 14% larger and 30% brighter than average full moons.
This occurs when the full moon aligns with lunar perigee (closest point to Earth).
On November 15, 2024, the Moon was approximately 224,853 miles from Earth.
This was further than the 2016 supermoon, which was the closest in recent history at 221,524 miles.
The Moon's distance from Earth varies due to its elliptical orbit, ranging from 253,000 miles (apogee) to about 226,000 miles (perigee).
November's full moon is also known as the Beaver Moon, Frost Moon, Freezing Moon, and Digging Moon.
The Beaver Moon name relates to beavers preparing for winter.

Drone Recharging Technology

A drone recharging technology was developed at the University of Southern Denmark.
Drones can now recharge using power lines.
An internal computer guides the drone to the nearest power line using radar and cameras.
The drone uses a specialized gripper to attach itself to the line.
A magnetic circuit then allows the drone to draw power.
A 9.5-pound drone recharged itself five times and flew for over two hours in tests.
Potential applications include power line inspections and maintenance.

Ancient Silver Coins Found

Metal detectorists discovered the Chew Valley Hoard, a collection of 2,584 silver pennies.
These are from the 11th century (1066-1068).
The coins were minted at 46 different locations in England.
The coins were found in a farmer's field in Chew Valley, Somerset, England.
The find was purchased by the South West Heritage Trust for $5.5 million in October 2024.
The discoverers will share half of the proceeds (approximately $2.8 million), while the land owner received the other half.
The coins primarily featured either King Harold II or William I, reflecting the Norman Conquest.
The find suggests the coins were likely buried for safekeeping.
Some coins are cut in half, which was a common practice for creating smaller money units.
The hoard is valued as equivalent to 500 sheep or the annual income of a sizable estate.

Wooden Satellite Launch

LignoSat, the world's first wooden satellite, was launched to the International Space Station (ISS).
It was launched aboard a SpaceX cargo capsule on November 5, 2024.
It is designed to test wood's resilience in space.
LignoSat is a collaboration between Kyoto University and Sumitomo Forestry.
Prior testing involved sending a panel with different woods to the ISS in 2022.
Magnolia wood was selected for the satellite based on testing results
The mission aims to reduce space junk by using a material like wood that leaves behind only water & CO2 instead of aluminum oxide, when burning up in the atmosphere.
LignoSat is expected to orbit Earth for six months, gathering data.

Student-Built Rocket Breaks Altitude Record

Aftershock II, a rocket built by USC students, broke a 20-year-old amateur rocket altitude record.
Launched from Nevada's Black Rock Desert on October 20, 2024.
It reached an altitude of 470,000 feet (143.3 km).
This surpasses the previous record of 380,000 feet (115.8 km), set by GoFast in 2004.
Aftershock II exceeded the previous speed record, reaching 3,600 mph (5,800 km/h).
The rocket successfully crossed the Kármán line (100 km altitude).
The titanium-coated fins and heat-resistant paint helped the rocket withstand extreme temperatures.
Real-time tracking was enabled by the student-designed computer systems.
Future focus will be on sounding rockets to carry scientific instruments.

Winter Solstice 2024

The winter solstice in the Northern Hemisphere occurs on December 21, 2024.
It marks the shortest day and longest night of the year.
The Southern Hemisphere experiences the summer solstice on the same day.
Earth's tilt affects sunlight distribution across hemispheres.
Winter solstice has held symbolic importance for various cultures.
Stonehenge and Newgrange, built for solstice ceremonies, are popular destinations.
Cities like San Francisco and Anchorage have unique winter solstice traditions.
