Chasing New Horizons, continued

51m+Ih4C2FL._SX327_BO1,204,203,200_In 2015, the New Horizons Spacecraft flew past Pluto. Because Pluto is so far away, it took nearly 10 years of travel for the spacecraft to reach that distant dwarf planet — and that was after a decade of work to get the spacecraft to the launch pad. Planetary scientists Alan Stern and David Grinspoon have written a new book, called: “Chasing New Horizons: Inside the Epic First Mission to Pluto”. The book tells the story of developing and operating the New Horizon mission.

How on Earth’s own Joel Parker is also a scientist on the New Horizons mission, and he had a chance to chat with Alan and David about their book. Last week we heard the first part of this interview. In today’s show, we present Part 2 of that interview.  You can also listen to the full extended interview.

Chasing New Horizons – full extended interview

51m+Ih4C2FL._SX327_BO1,204,203,200_Here we provide the full interview by How on Earth’s Joel Parker of planetary scientists Dr. Alan Stern (Southwest Research Institute) and Dr. David Grinspoon (Planetary Science Institute), about their new book: “Chasing New Horizons: Inside the Epic First Mission to Pluto“. Their book describes the the story of Pluto and NASA’s New Horizons mission, bringing the reader backstage to hear the details and meet the personalities behind building, launching, and flying this audacious mission.

Excerpts of this interview were first broadcast on KGNU on May 15th and May 22nd.

Chasing Shadows – Stellar Occultations and the Outer Solar System

Chasing Shadows [starts at 9:40]  Astronomy is a science that depends on watching things happen in the universe that we don’t have control over: supernovae, formation of stars, orbits of planets, and the spectacle of solar eclipses.  You can’t grab a distant galaxy and bring it into the lab for experiments, so astronomers have to depend on studying the light that fortuitously comes to them from distant objects.  However, by studying just that light, we can learn much about the objects in the universe and how they formed and evolved.  For example, studying solar eclipses have taught us about the corona of the sun and about general relativity.   To make those observations and measurements, scientists have to chase the shadow and set up their laboratory in remote places to catch it.  In this edition of How on Earth we talk with one such shadow-chaser: astronomer Dr. Marc Buie from the Boulder office of the Southwest Research Institute.  Marc organized a set of expeditions around the Earth to observe occultations of the Kuiper belt object 2014 MU69, which is is the next flyby target of the New Horizons space mission that flew past Pluto in July 2015.  He explains the science of occultations, what can be gleaned from these shadowy observations of 2014 MU69, and talks about planning for observation expeditions to remote places around the world.

Grad School Science

Neuro_lab112.1.2_student-and-faculty-in-lab-e1374187050580

What is graduate school and how does it differ from the undergraduate experience?  What drives people to go through another 4…5…6…or more years of school? Today’s show features some people who might be able to tell us about the grad school experience in the sciences.  We have three grad students from the University of Colorado at Boulder:
* Joe Villanueva in the Molecular Cellular and Developmental Biology department.
* Annie Miller, in the Integrative Physiology department.
* Marcus Piquette, in the Astrophysical and Planetary Science department.
Each of them works in a lab with an advisor and is doing projects that will eventually lead to a thesis and getting a PhD, and they talk about what they do and what grad school is like.
