 The Parker Solar Probe was launched on August 12, 2018,

with a mission to study the outer corona of the sun. As the closest spacecraft to the sun, it embarks on a daring journey, entering the sun’s atmosphere to gather invaluable data. This unprecedented proximity allows scientists to study solar winds and their effects on space weather, which can have profound implications for Earth Historic Approaches to the Sun RecordBreaking Approaches:

 

The Parker Solar Probe has accomplished a series of recordbreaking maneuvers, including its closest approach to the sun on Christmas Eve 2024. Key Milestones: The probe has completed multiple close encounters, each revealing new insights into solar activity. Significance: These historic approaches not only enhance our understanding of solar phenomena but also help in predicting solar storms that can affect satellites and power grids on Earth Discoveries and Findings Unveiling Solar Secrets: The Parker Solar Probe has made groundbreaking discoveries, such as unexpected patterns in solar winds and insights into magnetic fields that surround the sun.

Enhanced Understanding: Findings from the probe are crucial for understanding solar flares and coronal mass ejections, which can disrupt communications and navigation systems on Earth. Impact on Solar Science: The data collected is paving the way for advancements in solar science, allowing researchers to develop better predictive models for solar weather Understanding the Enrichment Centrifuge A Key to Uranium-235 Extraction What is an Enrichment Centrifuge? Purpose: Extracts the uranium-235 isotope from natural uranium. Significance: U-235 is fissile, crucial for sustaining a nuclear chain reaction.

The Basics of Uranium Isotopes Natural Uranium Composition: 99.3% uranium-238 (U-238) 0.7% uranium-235 (U235) Importance of U-235: Nuclear reactors: Require 3% to 20% U-235. Nuclear weapons: Need around 90% U-235
