A space telescope launch + Alvin submersible check-up

The Nancy Grace Roman Space Telescope is scheduled for an early launch at the end of August. It will rest about a million miles from Earth at Lagrange point 2, where forces of gravity and motion balance out, allowing it to orbit the sun in sync with the Earth. The Roman Telescope is designed to collect masses of data that could inform questions about dark energy, dark matter, and exoplanets. Jackie Townsend, project manager for the mission, joins Host Flora Lichtman to discuss the telescope’s backstory, and what scientists hope it will do.

Then, turning from deep space to deep oceans, Anthony Tarantino of the Woods Hole Oceanographic Institution joins Flora to describe the recent maintenance and recertification process for the famous Alvin deep-sea submersible. It’s more than an oil change: The process involves disassembling the vehicle down to the bare frame. 

Guests:

Jackie Townsend is project manager for the Nancy Grace Roman Space Telescope mission. She’s based at NASA’s Goddard Space Flight Center. 

Anthony Tarantino is program manager for the Alvin Group at the Woods Hole Oceanographic Institution.
