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 Heat Test

-
Image
Objective: Since the GoPro cameras most likely failed due to sun heat during the 2017 launch, we will simulate the environment using a heat lamp, testing whether the cameras will record until its battery depletes, or will automatically shut down prior due to excessive heat. Method: We will set up the cameras in their cases and their respective positions in the payload box. The side cameras (labeled #2 and #3) will be connected to one fully charged power bank (10,000mAh), and the top camera (labeled #1) will be connected to another fully charged power bank by itself. The cameras will start recording before we set them in their cases and into the payload box. A heat lamp will be hung from a steel pole, and its heat will be directed towards the top camera. A thermometer connected to the back of the top camera (since the battery is there) is also on the steel pole within the camera’s field of view so that it can record changes in its temperature, so that in case it fails, we can...

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...
