'Touching' the sun

Early Saturday morning, NASA plans to launch a mission unlike any before it — this one is going to “touch” the Sun.

At 3:33 a.m. EDT, the Parker Solar Probe will launch from Space Launch Complex 37 on Florida’s Cape Canaveral Air Force Station. It will hitch a ride into space aboard a United Launch Alliance Delta IV Heavy rocket, and an upper stage boost from the rocket will send it hurtling out of Earth’s orbit and on a path to Venus, eventually moving at speeds up to 700,000 kmh (430,000 mph) — faster than any probe that came before it.

Seven years in space

Over the next seven years, the Parker Solar Probe will fly by Venus seven times, using the planet’s gravity to bring itself closer to the Sun each time. Ultimately, it will find itself within the outermost part of the Sun’s atmosphere, an area known as the corona. This will place the probe just 3.8 million miles from the Sun’s surface — seven times closer to the star than any craft that came before it, according to NASA.

While being the first agency to “touch” the Sun is a reward in and of itself, NASA expects to get much more than street space cred from its Parker Solar Probe mission. The probe will contain four instrument packages designed to, among other things, trace the movement of energy and heat within the corona and help scientists figure out what accelerates solar energetic particles and solar wind.

A learning opportunity

Ultimately, the more we can learn about the Sun, the better. Disturbances in its solar wind can have an impact on near-Earth space, which can affect our planet’s satellites. These disturbances can also create complications as we attempt to send astronauts and spacecraft farther away from the Earth.

Additionally, the Sun is the only star we can study up-close, and any insights we glean from the Parker Solar Probe could help us better understand how other stars function. Perhaps these insights will even inform our understanding of how life began on Earth, helping us narrow down our hunt for life beyond it.
