Here is a storehouse for active and recent Far Horizons projects. Every near space flight involves a range of scientific and engineering challenges. The Far Horizons team has over 7 years of experience in designing a wide range of scientific experiments and flight components. On this page you'll find proposed, working and completed projects from the last couple of years. We hope they can help to inspire your own projects or help you build from our experience. If you have some suggestions, experience or improvements on any of our projects, we'd like to hear from you. Do-it-yourself space exploration is a group effort.

Ground-Based Telescopic Tracking System for HAB Missions

1.1 Project Description Far Horizons High Altitude Balloon (HAB) missions routinely reach altitudes of 30km (100,000ft). Presently, the data from flight experiments are only obtained after the successful recovery of the payload. Live telemetry and 2-way communications is an ultimate goal for our missions. As a step in that direction, we plan to design and build a remote observing system to monitor flights in real time using telescopes at the Adler or in the field that will observe the flights. This system will be the foundation of a ground-based communications system for future HAB and CubeSat missions.

1.2 Target Goals

1.2.1 Create a telescopic system which can maintain a visual lock on the balloon in a typical FH HAB mission within a 2° FOV over the duration of the flight from any ground location.
1.2.2 Demonstrate the repeatability of the system.

Sun Sensor and Attitude Control System for HAB Missions

2.1. Project Description Over the past year the Far Horizons Project (with assistance of 2011 IMSA intern Josh Fornek) designed and tested a passively stabilized instrument frame for use in High Altitude Balloon flights. The frames utilize a method of mass distribution to increase the moment of inertia of the instrument frame. This has greatly increased our ability to collect scientific data requiring precision pointing. To perfect this system and allow our missions to perform a variety of precise astronomic and field observations, we need to increase the pointing accuracy to a precision of >1°/s. Participants on this project will research active stabilization methods, design and build systems for in-flight tests and design methods for the determination of accuracy.

2.2. Target Goals The final system will be required to demonstrate a pointing precision better than 1°/s.

HAB Altitude Control System

3.1. Project Description Small-scale HAB flights (≤3000g latex balloons) are historically dependent on local conditions. HABs are a passive vehicle primarily controlled by prevailing winds. For safety, improved experiment-dependent data collection and flight control, the utilization of an altitude control system offers the possibility of longer and more effective missions. Interns involved in this project will research, design, build, lab test and perform in-flight proof of concepts of their system. Maintaining a target altitude within a range of ±150m over 30 minutes is the goal of this project. Possible approaches include controlled pressure venting and ballast management.

3.2. Target Goals

3.2.1 The system will need to reach and maintain a specified target altitude and maintain that altitude within a range of ±150m over 30 minutes.
3.2.2 The system will be able to actively achieve an ascent velocity alteration from the average flight baseline of ±20%

Hydrogen Balloon

4.1. Project Description Helium and Hydrogen are two common lift gases used for HABs. The Far Horizons Project has used Helium for HAB launches because it is efficient and is a safe inert gas. With the current helium shortage, the use of hydrogen is becoming a more pressing option. Before a switch can be made from Helium to Hydrogen, specialized launch procedures are needed to the insure safe use of hydrogen.

4.2. Target Goals The successful use of Hydrogen for HAB flights will require:

4.2.1 A specialized launch procedure to ensure safe handling and flights;
4.2.2 Documentation supporting the above procedures
4.2.3 Successful and safe proof of concept before initiation of full scale hydrogen flight

Because of the high velocities required for this flight, the rocket's body will need to be able to handle very large stresses.

The rocket also has to be efficiently designed to prevent the generation of high temperatures around the body of the rocket.

Two Way Communication System

9.1. Project Description Other than the real-time reception of GPS data via HAM radio channels and via the APRS system, all data from Far Horizons flights are collected after the successful retrieval of the payload and its contents. Effective 2-way communication between the payload and mobile or land-based receivers would allow the real-time collection of experiment data, flight status and flight safeing. Toward this end, this project would create an effective and reliable downlink and uplink system for use throughout FH flights. A future application of this system could include communications for a CubeSat mission, so additional considerations of the system design should be sympathetic to this capability.
