The first test will be our ability to command because we have a known issue: the spacecraft power amplifier will not turn on automatically. This component boosts output power to reach Earth, but we leave it off on Earth as broadcasting at this massive energy level is dangerous to people. During additional testing post-integration on the rocket, we noticed that the line of code to turn on the power amplifier would not work. So, before we hear from the spacecraft, we'll need to command the power amplifier manually until we push a small software update.
We’ll attempt to command this small software update during the first pass via a dish in Australia, owned by Capricorn. We have conducted full testing at this dish and understand how to work with them; they were the ground station provider we brought in to help us recover from the first mission. The term “pass” refers to the period when a spacecraft is visible from a ground station. For a spacecraft in LEO, a pass is typically the time for the craft to fly overhead—usually around 45 minutes. For us, however, a pass can last up to 12 hours.
Over the next eight days, command and data will be performed using a plethora of large dishes around the world. The challenge here—still being worked on—is scheduling time. We want to do our best to ensure that we can transmit and receive simultaneously; however, it appears that this will be somewhat of a luxury. This means that at some point during this mission it’s likely we’ll need to do a “blind update” (executing a command without having first received data back).
