Asteroid Exploration

Paul Abell, NASA Johnson Flight Center

I will present the current status of NASA’s Asteroid Redirect Mission (ARM) that is planned for launch in December 2021. Specifically I will discuss how a solar-electric powered robotic spacecraft will visit a large near-Earth asteroid (NEA), collect a multi-ton boulder from its surface, perform a planetary defense technique at the NEA, and return with the boulder into a stable orbit around the Moon. I will also discuss how astronauts aboard an Orion spacecraft will subsequently explore the boulder, conduct investigations during their extravehicular activities, and return samples to Earth. I will demonstrate how the ARM is part of NASA’s plan to advance technologies, capabilities, and spaceflight experience needed for a human mission to the Martian system in the 2030s. Finally I will discuss how the ARM and subsequent availability of the asteroidal material in cis-lunar space, provide significant opportunities to advance our knowledge of small bodies in terms of science, planetary defense, and in-situ resource utilization (ISRU).

Preparing to Explore the Universe with the James Webb Space Telescope

Dr. Jane Rigby (NASA Goddard, Deputy Project Scientist for JWST)

Abstract: NASA’s James Webb Space Telescope (JWST), scheduled to be launched in 2019, will revolutionize our view of the Universe.  As the scientific successor to the Hubble Space Telescope, JWST will rewrite the textbooks and return gorgeous images and spectra of our universe.   In my talk, I will show how JWST will revolutionize our understanding of how galaxies and supermassive black holes formed in the first billion years after the Big Bang, and how they evolved over cosmic time.  I’ll describe how our international team is preparing for launch, how we decide what targets to observe, and how we are testing the telescope to be sure it will work in space.
