*Q1. Why are we making this?*
6 1 Jeremy Wright
7 5 J. Simmons
*A1*. _Adler's original motivation for developing the *Far Horizons Project* High Altitude Balloon (HAB) program was to act as a gateway to developing "CubeSats":  Adler's design is highly influenced by assistance from L. Paul Verhage and his "book":  The *Far Horizons Project* has the added benefit of providing educational opportunities to practice near space missions with students and enthusiasts which fits in with Adler's goals of "democratizing space exploration":

*Q2. Who is this for?*
10 1 Jeremy Wright
11 6 J. Simmons
*A2*. _The *Far Horizons Project* is for anyone who wants to build experience in the are of near space missions.  This includes schools and school clubs, scouting troupes, Makers and Maker Spaces.  Adler's goal is to help groups get the experience to fly their own missions._

*Q3. How will this be used?*
14 1 Jeremy Wright
15 6 J. Simmons
*A3*. _The HAB provides a platform to carry scientific and engineering payloads (no more than 12 lbs of total vehicle weight with individual payloads of 6 lbs or less) to a near space environment (exposing the vehicles and payloads to very low pressures and temperatures, and radiation levels significantly higher than those experienced on the ground) for a duration on the order of a couple of hours._

*Q4. What features does it need to have (now)?*
18 1 Jeremy Wright
19 7 J. Simmons
*A4*. _The test stand needs to:
20 7 J. Simmons
21 7 J. Simmons
* Operate safely throughout its flight (in accordance with "FAR 101":
22 7 J. Simmons
* Operations should be flexible to deal with changing conditions on the ground (including adjusting for weight restrictions, winds, or other unexpected launch conditions)
23 7 J. Simmons
* The HAB needs to be trackable to facilitate recovery operations
24 7 J. Simmons
* The HAB needs to provide a soft landing
25 7 J. Simmons
* The HAB needs to support carrying experiment payloads (each payload container limited to 6 lbs)
26 7 J. Simmons
* The HAB total system weight must be under 12 lbs
27 7 J. Simmons
* The HAB should carry the payload to between 90 kft and 100 kft_

*Q5. What features does it need to have (later)?*
30 1 Jeremy Wright
31 8 J. Simmons
*A5.* _Desired enhancements include:
32 8 J. Simmons
33 8 J. Simmons
* Controlled descent system (guided landings using parafoil kite to either hit or avoid landing sites)
34 8 J. Simmons
* Live two-way telemetry (or command & control) and the ability to receive live experiment and operations data
35 8 J. Simmons
* Stabilized platform system (Adler is making progress on this one)
36 8 J. Simmons
* Alternative balloon configurations (zero-pressure, super-pressure balloons)
37 8 J. Simmons
* Alternate lift gasses (Adler uses helium right now)
38 8 J. Simmons
* A structure to hold the balloon during filling operations and to automatically stop the filling operation for the desired lift_

*Q6. What are the legacy requirements?*
41 1 Jeremy Wright
42 9 J. Simmons
*A6*. _The HAB must comply with FAA regulations ("FAR 101":
43 1 Jeremy Wright
44 1 Jeremy Wright
*Q7. Who's going to build this?*
45 1 Jeremy Wright
46 9 J. Simmons
*A7*. _Small teams (2-3 members minimum) of volunteers and space enthusiasts.  The designs are openly licensed so anyone can put together a team to build and operate a *Far Horizons Project* HAB.  Note, while the technical requirements to build the HAB are small, an amateur radio license is required to run the tracking radios during missions._
47 1 Jeremy Wright
48 1 Jeremy Wright
*Q8. How many do we want to make?*
49 1 Jeremy Wright
50 4 J. Simmons
*A8*. _One per launch (during design phase look into what components can be reused)._
