Punch prepares for launch. NASA's polarimeter to unify the corona and heliosphere mission will capture images of the sun's corona transitioning to the solar wind, making this invisible system visible for the first time.

Mission principal investigator Dr. Craig DeForest discusses what punch will uncover about the heliosphere, space weather, and its impact on Earth.

That's next on this episode of Technology Today.

Hello and welcome to technology today. I'm Lisa Benia.

NASA's polarimeter to unify the corona and heliosphere or punch mission will achieve a first imaging the solar wind as it

streams out of the sun. Four suitcase-sized satellites equipped with special instruments and

designed and built by SWRI will produce the first 3D images of the inner heliosphere, shedding light on the sun, solar, wind, Earth

system. How will punch instruments make the invisible visible? What will we learn from this

groundbreaking mission? Punch Principal Investigator Dr. Craig DeForest of SWRI's Solar System Science

and Exploration Division joins us for a pre-launch discussion.

He's here at SWRI San Antonio headquarters for one day from Boulder, Colorado.

So thank you so much for being here during this especially busy time, Craig, and spending time with us on your one day in town.

Thank you for having me down. It's wonderful to be here.

So we'll get to your preparations for launch day, a huge day coming up, and we'll talk about that in just a bit.

But first, punch is set to explore the inner heliosphere and uncover never before seen images and data. So let's get into it. I want to start with

understanding some of the terminology associated with the mission. So during this conversation,

we'll be talking about the corona, heliosphere, the solar wind. So will you define these
