Overview
NASA
selected Psyche as the 14th Discovery mission on Jan. 4, 2017. Led by Arizona
State University, Psyche will be the first orbiter of a M-class asteroid,
(16) Psyche. The mission design is based on NASA’s Dawn mission at Vesta
& Ceres, and uses instruments with a strong heritage from past missions.
Our science objectives are to answer the following questions: 1) Is Psyche an
exposed planetary core, or did it never undergo melting? 2) What are the
relative ages of features on its surface? 3) Do small metal-rich bodies
incorporate light elements expected to be inside Earth’s high-pressure core?
4) Did Psyche form under more oxidizing or more reducing conditions than
Earth’s core? and 5) What is the topography of this metal world? Psyche will
launch in Aug. 2022 and will enter orbit of (16) Psyche in Jan. 2026 for a
21-month nominal mission. Psyche will study the surface using a pair of
multispectral imagers (clear filter & 7 color filters, for surface
morphology, stereo topography, and detection of certain key mineral classes),
a gamma-ray & neutron spectrometer (for elemental abundances), and dual
fluxgate magnetometers (to search for a remanent magnetic field). A gravity
investigation using tracking of the spacecraft’s radio signal is also
planned. Psyche will characterize surficial geologic features, topography,
and compositions through four consecutively lower orbital phases, each
optimized to obtain data to accomplish our science objectives. Psyche will:
1) map ≥80% of the surface with long-l filters at ≤500m/pix
(assess metal to silicate fraction), 2) map ≥80% of the surface with
short-l filters at ≤200m/pix (spectral detection of oldhamite,
(Ca,Mg)S), 3) map ≥50% of the surface with clear filter at
≤200m/pix (crater counting), 4) map ≥80% of the surface with
clear filter at ≤20m/pix (geologic mapping), and 5) determine the shape
of (16) Psyche by mapping with clear filter over ≥80% of its surface
with ≤200m/pix using stereo imaging techniques. This presentation
discusses details of our mission.
About the
Speaker
Dr. David A. Williams is a Research
Professor in the School of Earth and Space Exploration at Arizona State
University, Tempe, Arizona. Dr. Williams is the Director of the Ronald
Greeley Center for Planetary Studies, a NASA-supported planetary data center
at ASU. He is also the Director of the NASA Planetary Aeolian Laboratory,
which administers wind tunnels the Ames Research Center in California. David
is currently performing research in volcanology and planetary geology, with a
focus on planetary mapping, geochemical, and remote sensing studies. His
current research focusses on planetary geologic mapping of bodies across the
Solar System, and computer modeling of the physical and geochemical evolution
of lava flows in a variety of planetary environments. He was involved with
NASA’s Magellan Mission to Venus, Galileo Mission to Jupiter, Dawn Mission to
asteroid Vesta and dwarf planet Ceres, and ESA’s Mars Express orbiter
mission. He is a member of the Janus camera team for the ESA JUICE mission,
and he is currently Deputy Imager Lead and a Co-Investigator on NASA’s Psyche
Mission, scheduled to launch in August 2022. In 2014 David was elected a
Fellow of the Geological Society of America, and asteroid 10,461 DAWILLIAMS
was named in his honor.

Neural Interfaces for Controlling Finger Movements

Overview
Brain
machine interfaces or neural prosthetics have the potential to restore
movement to people with paralysis or amputation, bridging gaps in the nervous
system with an artificial device. Microelectrode arrays can record from
hundreds of individual neurons in motor cortex, and machine learning can be
used to generate useful control signals from this neural activity.
Performance can already surpass the current state of the art in assistive
technology in terms of controlling the endpoint of computer cursors or
prosthetic hands. The natural next step in this progression is to control
more complex movements at the level of individual fingers. Our lab has
approached this problem in three different ways. For people with upper limb
amputation, we acquire signals from individual peripheral nerve branches
using small muscle grafts to amplify the signal. Human study participants
have recently been able to control individual fingers online using indwelling
EMG electrodes within these grafts. For spinal cord injury, where no
peripheral signals are available, we implant Utah arrays into finger areas of
motor cortex, and have successfully decoded flexion and extension in multiple
fingers simultaneously. Decoding “spiking band” activity at much lower
sampling rates, we recently showed that power consumption of an implantable
device could be reduced by an order of magnitude compared to existing
broadband approaches, and fit within the specification of existing systems
for upper limb functional electrical stimulation. Finally, finger control is
ultimately limited by the number of independent electrodes that can be placed
within cortex or the nerves, and this is in turn limited by the extent of
glial scarring surrounding an electrode. Therefore, we developed an electrode
array based on 8 um carbon fibers, no bigger than the neurons themselves to
enable chronic recording of single units with minimal scarring. The long-term
goal of this work is to make neural interfaces for the restoration of hand
movement a clinical reality for everyone who has lost the use of their hands.
About the
Speaker
Dr. Cynthia A. Chestek received the B.S.
and M.S. degrees in electrical engineering from Case Western Reserve University
in 2005 and the Ph.D. degree in electrical engineering from Stanford
University in 2010. She is now an associate professor of Biomedical
Engineering at the University of Michigan, Ann Arbor, MI, where she joined
the faculty in 2012. She runs the Cortical Neural Prosthetics Lab, which
focuses on brain and nerve control of finger movements as well as to
high-density carbon fiber electrode arrays. She is the author of 53
full-length scientific articles. Her research interests include high-density
interfaces to the nervous system for the control of multiple degree of
freedom hand and finger movements.
