Section 1.0 – Pre-Flight Preparations

Section 1.1 – Mission Overview

Purpose of Flight

The purpose of the ALTAIR 16 flight is to provide an engineering test of all flight and operational systems and to attempt to procure quantitative science imagery of the LED diffusive light source. The two principle systems under test are the science system including telescope pointing and imaging, and the parafoil recovery system.

The current gondola was developed after the loss of A13 and was flown during the A14 and A15 missions. The A14 flight revealed some significant issues, but we believe these have all been resolved. The A15 flight was operationally largely successful, but we failed to produce any usable science imagery. The two possible causes were a lack of pointing accuracy or a lack of synchronization, or both. Both these issues have been addressed. The suspension rigging and parafoil deployment system has been changed dramatically since A13. It functioned correctly for A14, but apparently did not fully deploy during A15, resulting in a spiral descent. The most likely cause was misrigging before launch. No other defects have been uncovered. Validation of correct deployment is still a major objective of this mission.

Some aspects of the descent navigation software have been improved since A13 and because of the parafoil problem remain unvalidated, so it is an objective to gather flight characteristics data and to develop a workable steering strategy to bring the parafoil to a landing at the designated recovery site.

The diffusive light source has been tested in the lab and roughly calibrated. Although the platform may not be fully stable in this flight, obtaining quantitative imagery should be possible, and is a major objective of the mission. We intend to make observations on climb as usual, and also during descent when the gondola is more stable.

The SPOT Trace worked effectively on A14 and A15, and remains installed. It is a mission objective to demonstrate its functionality at altitude.

This flight will continue the process of gradually increasing cutdown altitude.

Payload:- Science firmware- Science protocol- Diffusive light source- Parafoil deployment at higher altitude with new rigging.- Parafoil controllability
