Solar Storms: NASA's New Mission to Unravel Space Weather Mysteries

California, USAThu Jul 24 2025

Space weather is a big deal, and NASA is taking steps to understand it better.

On a recent Wednesday, two satellites were sent into space from California on a SpaceX rocket. This mission, called TRACERS, is set to study the polar cusps, areas in Earth's magnetic field near the poles. These areas are key to creating the beautiful auroras we see, but they also play a role in geomagnetic storms that can cause serious problems.

The Impact of Geomagnetic Storms

These storms can mess with:

  • GPS
  • Radio communications
  • Power grids
  • Satellites

They're usually caused by solar flares or coronal mass ejections, which send blobs of plasma into space. When these blobs hit Earth, we get auroras, but we also face the storms' harmful effects.

Real-World Consequences

  • A strong geomagnetic storm last year caused over $500 million in losses for the agriculture sector.
  • In 2022, a period of high solar activity led to the loss of 40 SpaceX Starlink satellites.

The TRACERS Mission

The TRACERS mission aims to spend at least a year measuring plasma conditions in these polar cusps. Understanding space weather is crucial, as it can have significant impacts on our technology and daily lives.

The launch was initially delayed due to a power outage that disrupted air traffic control, but it eventually took off on Wednesday.

questions

    How do the polar cusps contribute to the formation of auroras, and what specific mechanisms are involved?
    If auroras are caused by plasma from the Sun, does that mean we should blame the Sun for our bad hair days?
    What if the polar cusps are just Earth's way of showing off its cosmic dance moves with the Sun?
