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).


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).


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)


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)


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”.
