Week 3, Thursday

General We ran a new simulation of the flight trajectory using the CUSF Landing Predictor 2.5 and searched for the displayed landing coordinates on Google Maps. If launched today, the payload would land at 41.2763 N, 74.8146 W, which is in Sandyston, New Jersey near the Delaware River. If launched a week later on June 13th, the payload would land at 42.8818 N, 74.9573 W, which is in Warren, New York in or near Cullen and on a farmyard (amidst some hay bales). CAD The good news is that the lid has been printed. The bad news is that it is too thick to fit into the rim. Work is underway to fix the component's model and reprint it. Hardware & Software A new circuit board is being printed. Cameras We are testing the cameras in direct sunlight to determine if they will fail. We also reviewed the footage of prior launches to better prepare for the payload's retrieval.

Camera Field of View Test

-
Image
Objective: To test which GoPro field of view if most optimal for the side camera to record the tray opening and closing. Gaining footage of the horizon is also a secondary goal. Method: GoPro Hero 3+ Silver, the camera that will be used for the sides, was mounted in its casing and payload box to simulate recording on the day of the flight. A previous model of the petri dish assembly will be positioned at various distances on the side. A ruler was used to measure the distance of the payload from the petri dish assembly to record different distance possibilities. The camera was recorded at 1080p and 60fps.   Camera mounted into the new, lightweight casing.  Using a standard ruler to measure distance. Below is a diagram of all the possible frames of second and fields of view for each resolution within GoPro Hero 3+ Black, the camera that will be used for the top.  It has been determined for the side camera to record at 60fps at 1080p, in which t...

Zachary touched up the poster, Ian finalized the abstract, and Sadik is trying to graph the test flight data. We also measured the parachute-to-balloon cord and the parachute-to-package cord, which were 37' and 29' 4", respectively. In the meantime, the biologists took our remaining 5 Petri dishes to sterilize them and add agar for the launch. This leaves us with one Petri dish for testing. Yesterday, we finished rendering the payload in Fusion 360. This included two Petri dish assemblies, two Spot GPS holders, one APRS holder, one battery holder with two batteries and three camera casings (two in the box, one in the lid). The circuit board has not been included yet; we're still waiting for the digital pressure sensor and thermistor.
