THE CHILEAN SPACE APPS CHALLENGE
Our Challenge
Develop a mission concept to explore Apophis (or any other
significant asteroid) to better predict its orbital dynamics and to instrument
the object with a radio transponder prior to the 2029 close approach.
Team "Tuor": Carlos Aguilera, Rodolfo Novakovic, Erik Vallejos, Anton
Rabanus, David Rabanus
IDEAS, DETAILS
•Tagging and tracking of only one asteroid (this challenge)
does not make sense when there are >100.000 unknown objects in the asteroid
belt that potentially can pose a risk to life on earth and require to be
tracked.
•For a better orbit prediction it is required to know the
forces that act on an asteroid.
•To calculate these forces, position and velocity vector of
each of the objects need to be obtained
•Learning from the concept of WISE (NASA mission from
2010/2011, and continuing the observations).
•Lagrange-2
orbit at Mars: Half way to the Main Asteroid Belt (4x more signal!)
•CubeSat (Ardusat!)
platform, 3U form factor
•Hitching a
ride to Mars (~150kg ballast load)
•Swarm (“enjambre”) de >4
replicas
•Miniaturized
ion thrusters for propulsion from Mars to L2@Mars, and attitude control
•Power from
solar panels
•Telemetry/downlink
via amplified CubeSat system
•Rotation-cone-scanning
thermal IR telescope
•3x
cell-phone CCD as star trackers
•Linux
on-board processing of images (“stacking”) and data reduction
•200mm
space-foldable telescope
•11 and 19 arcsec resolution
•2x Peltier-cooled microbolometer arrays
•10µm and
18µm color channels: main emission wavelength of asteroids
INTERPLANETARY MISSION DESCRIPTION RESULTS
•Download
through amateur deep space network
•Post-processing
at earth-bound facilities:
oChecking of data quality
oIncentive optical follow-up
observations (validation)
oIngest orbital parameters of found
asteroids into JPL database
oCalculate proximity values to Earth
orbit
•Visualization
via web-based access to database
