Scheduled to launch in 2027, Dragonfly will be the first spacecraft to fly on Saturn’s moon, Titan. Data from Cassini-Huygens revealed evidence of a subsurface ocean, made of water and ammonia, as well as stable bodies of liquid hydrocarbons on the surface. This makes Titan the only other body in our solar system with a stable liquid source on its surface. These features make it an incredibly valuable place to study in humanity’s search for life beyond Earth. As Dragonfly is also a rotorcraft an...

This episode features a roundtable discussion between myself, Adi Khuller, Joe Mayer, and Omar Alavi about life as engineering students and how we balanced working on projects and coursework at ASU. This diverts from my usual content on space mission engineering, but it is a topic I feel is important to focus on, as this is something that many students struggle with on some level. Given that, if you’re a student, I hope you enjoy this conversation and that it helps you or gives you comfort in so...

This episode includes a conversation with Adi Khuller, Joe Mayer, and Omar Alavi on the design and implementation of Pulsed Plasma Thrusters (PPTs) and how these can be integrated into CubeSats, specifically. Adi, Omar, and Joe were the core of a group of people who designed and prototyped a state-of-the-art PPT system for CubeSats during their undergrad at ASU. Their PPT was developed entirely by student-driven efforts and limited student organization funding. In this conversation we’ll talk ab...

A mission’s scope, budget, and schedule are all very intertwined, and all are an important part of setting the foundation and feasibility for a project. This makes for a rather complex recipe within space mission development. However, it also means that there is a great deal of knowledge that can be gained from this topic. Episode 23 features a conversation with Dr. Tobin Anthony (CEO) and Chris Costello (President) of Space Systems Integration, LLC. In it, we explore aspects of mission developm...

Frequency licensing is one of the most important logistics when it comes to preparing spacecraft for launch. Spacecraft must have this before they are allowed to transmit or receive on a frequency, and therefore, they must be licensed in order to launch. This episode features a conversation on frequency licensing with Alicia Johnstone, who is the resident expert on licensing at Cal Poly and has helped many CubeSat missions with the licensing process throughout her career. The discussion covers e...

LunaH-Map is a 6U CubeSat, which will map the location and quantity of hydrogen in permanently shadowed regions of the lunar south pole. In doing so, the spacecraft will help scientists and engineers quantify the amount of water available in this region, which can then be used to help humanity live on the moon, sustainably. Measurements will be collected using a neutron spectrometer, which was developed with the resolution and volume requirements necessary for this mission. In this episode, I ch...

Chemical propellant has enabled spacecraft to explore other planets in ways that people once thought impossible, but, in the grand scheme of exploring our solar system and going beyond it, this can ultimately only get us so far. Enter electric propulsion systems, which propel a spacecraft by using electromagnetic forces to accelerate a gas. This method provides several benefits over traditional propulsion systems, which will allow electric propulsion to play a key role in the future of space exp...

In space, a spacecraft can experience extreme hot and cold temperatures based on its distance from the sun and orbit around a planet. As a result, spacecraft incorporate a control system to maintain hardware within an allowable temperature range so they don’t become damaged. While thermal control systems are essential for spacecraft, modeling and designing these is not an easy or straightforward task. I n today’s episode I got to chat with JPL thermal engineer Belinda Shreckengost on several top...

Integrating a CubeSat is not not as easy as it sounds. In addition to housing all necessary hardware, the design has to meet requirements from the launch provider, account for cabling, and ensure everything is designed such that it can be easily put together and taken apart. The structure for the Phoenix CubeSat was developed and fabricated entirely by the student team with these ideas in mind, but we learned several lessons as we worked toward finalizing the structure design and assembly proced...

The flight software is the heart of a spacecraft. It dictates every action that the spacecraft takes. Because of this, it’s critical to ensure that the software is robust, and that it can support the mission in every possible way. Not only is the code itself important, but the way the software is managed and comes together is significant as well. Today’s episode features a roundtable discussion between myself, Craig Knoblauch, and Vivek Chacko as we discuss the lessons we learned over the years ...
