NASA to Launch 3 Rockets During The Solar Eclipse. Silver the Key to Space Travel.
The spacecraft will help NASA understand how Earth's ionosphere reacts to a sudden reduction in sunlight. Outcrop Silver Feature.
Introduction:
When you start up your vehicle daily, you concede that you depend on future energy.
Likewise, if you believe that aerospace, solar, electric vehicles, robotics, AI, and electronics are part of our future, then logic dictates silver is critical. Invest in Silver because Silver is scarce; meanwhile, demand is soaring.
Outcrop Silver is one of the World's pure silver miners. We favor Outcrop Silver for advancing high-grade deposits in a Top Tier Mining District.

Ever wondered how the upcoming total solar eclipse on April 8 might affect the ionosphere, that intriguing layer of Earth's atmosphere?
Well, NASA has and plans to find out using a trio of rockets.
This venture, aimed at understanding the impact of a sudden reduction in sunlight on the ionosphere, could help mitigate the radio and satellite communication errors known to occur during some eclipses.
The ionosphere, situated within the thermosphere, separates most of Earth's atmosphere from the vacuum of space. It's a sub-layer teeming with gas particles ionized or electrically charged by the Sun's radiation.
The Sun's influence causes the ionosphere to change between day and night, with the portion facing the Sun thickening due to increased ionization, while the part experiencing night thins as ionized particles relax.
While the regular day-night shift provides a predictable pattern of ionospheric fluctuations, a total solar eclipse throws a curveball. Creating a short-term artificial night, the eclipse introduces changes in the ionosphere that are much harder to predict.
These changes can disrupt radio and satellite communications, causing problems ranging from minor inconveniences to major disruptions in Earthly infrastructure or space operations.
To tackle this, NASA will deploy three sounding rockets, recoverable suborbital rockets carrying research equipment.
These rockets, part of the Atmospheric Perturbations around Eclipse Path or APEP project, were tested during the annular solar eclipse in October twenty twenty-three and recovered from New Mexico's White Sands National Park.
On April 8, these rockets will take snapshots of the ionosphere before, during, and immediately after the total solar eclipse.
One rocket will be launched from NASA's Wallops Flight Facility in Virginia, forty-five minutes before the Moon obscures the Sun. From a maximum altitude of two hundred and sixty miles, it will measure the density of charged versus neutral ionosphere particles and the sub-layer's magnetic field.
Four small secondary instruments will duplicate each of the rocket's measurements to ensure accuracy.
The same process will be repeated at the eclipse's peak, and again forty-five minutes after the peak.
Though coastal Virginia will only experience about eighty-one percent coverage during the eclipse's peak, the rockets launched from Wallops Island are expected to capture invaluable data about the ionospheric perturbations caused by the eclipse shadow.
These insights could be crucial in preventing high-frequency communication issues in the future.
Why is Silver used so Extensively in Space?
1. Exceptional Thermal Conductivity: Silver surpasses all other metals in efficiently transferring heat. This is crucial for spacecraft, satellites, and rockets that encounter extreme temperature swings in their journeys. Silver helps disperse heat generated by electronics and engines, preventing overheating and malfunctions.
2. Superior Electrical Conductivity: Silver's exceptional ability to conduct electricity makes it invaluable for spacecraft wiring, antennas, and circuit boards. This ensures reliable power transmission and signal communication in the harsh space environment.
3. Remarkable Corrosion Resistance: Silver, unlike many metals, doesn't readily corrode or rust, even when exposed to harsh vacuum and intense space radiation. This durability keeps sensitive equipment operational and extends the lifespan of spacecraft components.
4. Reflective Properties: Silver's high reflectivity plays a role in heat dissipation and can be used for specific applications like thermal control coatings and mirrors for telescopes and laser systems.
