Students of all
institutions
u This project is Ø For not only underrepresented and underserved students, but for all
students with any ethnicity and demographics. Ø STEM Pathways: from Middle/ High School to Advanced Degree
completion. Ø Involves Oahu and Big Island schools (UH-Manoa, lead), UH-Hilo,
Kapiolani Community College, Waiakea High School, Moanalua High School).
Ø It is expected to extend the project to Maui, Kauai and Lanai Islands. Ø Future work: Extensions to other Islands, initiation of new key projects Ø Supported by NASA (nearly $500,000), the prime collaborator – NASA Ames Research Center
HESTEMP: Overview
u Key projects address NASA Earth Sciences Missions: Ø Project 1: Atmospheric aerosol studies (Hawai’i) Ø Project 2: Studies of effects of ocean species and experiments
simulating phytoplankton’s influence on ocean color (Oahu, Hawai’i).
Ø Project 3: Studies of small satellite technology and its role in understanding of Earth sciences (Oahu).
Ø Project 4: Planetary Landing Technologies (Oahu) Ø Project 5: Unmanned Aerial Systems (Oahu, Maui, Lanai,
Kauai)
u New key projects: Ø Project 6: Deep Space Missions Ø Project 7: Any other ideas are welcome!
HESTEMP: Key Projects
u Key projects address NASA Earth Sciences Missions and designed for middle and high school students, community college students, university undergraduate and graduate students.
Ø Project 1: Atmospheric aerosol studies (Hawai’i)
Students - learn about atmospheric aerosols and then propose and build
their own instruments to monitor them; - use collected aerosol measurement data to generate and
discuss various graphs and diagrams; - compare and validate collected data with NASA’s publically
available satellite data.
HESTEMP: Key Project 1
Ø Project 2: Studies of effects of ocean species and experiments simulating phytoplankton’s influence on ocean color (Oahu, Hawai’i).
HESTEMP: Key Project 2
Students - study general principles of ocean color, as
well as the instruments used to measure it; - prepare written and video-based materials
for this study; - measure spectral absorbance and
fluorescence of seawater to demonstrate the concepts learned;
- collect seawater samples and use a spectrophotometer to obtain data about the samples;
- compare these sample spectra to pure and mixed cultures of phytoplankton.
Ø Project 3: Studies of small satellite technology and its role in understanding of Earth sciences (Oahu).
HESTEMP: Key Project 3
Students - study small satellite technology; - explore their maneuvers and benefits in understanding of
various phenomena, including Earth gravity variations, climate change, ocean monitoring and rising sea levels utilizing on-board sensors;
- conduct simulations of HiakaSat’s orbital and attitude dynamics using COSMOS, Matlab and Satellite Toolkit (STK);
- tour the HSFL facilities and attend presentations at HSFL and Mechanical Engineering featuring small satellite technology;
- perform hands-on simulations of a satellite flight, navigation and control capabilities through the integration of software with existing hardware, such as GPS and Inertial Measurement Unit (IMU) sensors and attitude test-beds of HSFL.
Ø Project 4: Planetary Landing Technologies (Oahu)
HESTEMP: Key Project 4
Students - study NASA space exploration missions, including previous, current and future Moon, Mars and asteroid missions; - study entry, descent and landing technologies (EDL); - explore and analyze various landing maneuver sequences and scenarios; - conduct simulations and hands-on projects on the design and simulation of EDL trajectories; - propose robotic missions.

Ø Project 5: Unmanned Aerial Systems (Oahu, Maui, Lanai, Kauai)
HESTEMP: Key Project 5
Students - study flight mechanics; - dynamical models of various UAS platforms, including fixed-wing aircraft, quadcopters, etc.; - design and assemble UAS using given requirements; - conduct simulations and hands-on projects using dynamical models; - study utilities of on-board sensors; - explore a wide range of navigation and control schemes; - work with flight controllers and their codes; - explore agricultural, scientific and other applications of UAS.
Ø Comprehensive Open-architecture Solution for Mission Operations Systems (COSMOS) is a complete operating system for managing all aspects of a collection of remotely distributed data acquisition nodes, both mobile and stationary.
Ø For this project, COSMOS will provide the device drivers for any hardware used to collect data.
HESTEMP: COSMOS
Ø Data would be made available to the central repository for both real time and archival access.
Ø Engineering Student Ambassadors (ESAs) Ø Annual One-day Mini-Conference (Mid May) Ø Communications between the students and NASA scientists
through “Google hangouts”, “Skype”, “Twitter”, etc. Ø Students will be encouraged to share their thoughts with their
peers, the SAs and experts.
HESTEMP: Activity Support
Ø Project Awards for Students: - Reward 6-8 students for the 2nd and 3rd years who have successfully
completed their key project and showed mentorship, leadership and STEM-skills, with a stipend.
- the stipends will be communicated with the student’s parents; - the project team will reward 3 groups for the design and performance
of “mini-projects” to reveal and/or utilize interesting phenomena in the science problems related to Projects 1-3 ($50 for each key project).
- the awards will be used to purchase parts and supplies to perform their “mini-projects”.
