After one month and 1.5 million kilometers of travel since its launch on Christmas, the James Webb Space Telescope is set to reach its orbit destination Monday. It’s the beginning of a profound shift in the way we see deep space: the telescope will be able to look back 13.7 billion years back in time. To get to this point has taken 10 billion dollars and a quarter of a century of work. For nearly all of that time, astronomer Marcia Rieke was on the project. As she waits for the telescope to thrust into orbit, we’ll talk with her about what it’s like to see a career’s worth of preparation finally come to fruition and what she hopes to learn from the telescope’s journey.
