Former NASA Deputy Administrator Lori Garver this week on Planetary Radio.

Welcome, I'm at Kaplan of the Planetary Society with more of the Human Adventure

across our solar system and beyond. Many give Lori Garver much of the credit

for opening the way to commercial success stories like

SpaceX. We'll talk with her about that and much more on today's show. That gigantic rocket,

the space launch system, took another step toward the sky with the

test last week.

Jason Davis was there, and he'll tell us about it.

Bruce Betts will help me celebrate the 4th of July with a couple of space anniversaries on that date.

We begin with a report from senior editor Emily Loch Duwala.

She was looking toward a 4th of July Extravagansa at Jupiter.

Emily, I think will be forgiven for talking Juno again, especially because the mission

has already delivered some science.

Yes, it has. In fact, all of the science instruments have been returning data as Juno approaches

Jupiter. For a while it was just taking data on the solar wind and you know interplanetary

space but Jupiter's magnetosphere is really enormous and so many days out from orbit insertion

Juno has already been capturing good data and they released a little bit of it yesterday.

I heard it described as the biggest structure in the solar system.

Yes, Jupiter's magnetosphere just expands across a huge region of space.

It's felt over an enormous area.

What happened about 10 days before orbit insertion is that Juno crossed between the part of interplanetary space where the sun is in charge to the part of interplanetary space where Jupiter is in charge.

It crossed from feeling only the solar wind
