Lunar Lion is a team of Penn State students and engineers from the Penn State Applied Research Laboratory. The team hopes to develop and land their spacecraft, the Lunar Lion on the Moon. The team is student run under the direction of Dr. Alexander Rattner, a mechanical engineering professor at Penn State's Multiscale Thermal Fluids and Energy.[1]

The team, which is privately funded, secured its first $2.5 million, most of which was internal funding, to get the project started.[2]

The team was formerly a competitor in the Google Lunar X Prize competition, but has since withdrawn.[3]

Narrator: NASA shows the Lunar Lion Team some tricks of the trade... That's right now, In Motion! Narrator: Penn State has assembled a team of specialized faculty and students to do what many would only dream. At least 'til now. The Penn State Lunar Lion team, in competition with teams from around the country and around the world, will attempt to be the first to launch a spacecraft from earth and land it on the moon. And while the team has brought together some of the smartest and brightest minds in the country to accomplish this task, Penn State sought out the assistance of what probably is the largest knowledgebase in the world on what it takes to accomplish space travel. Bilen SOT: They have a real expertise at rapidly developing mission concepts and showing whether they're viable or not. That's the kind of capability that they've developed over many years, they've proven it out over many different mission concept designs and being able to use them to help us flesh out whether the concepts that we had for the Lunar Lion were going to be viable or not was really really valuable to us. Narrator: So team members piled in a van during springbreak at Penn State and made the four plus hour journey to NASA's Glenn Research Center, located just outside of Cleveland, Ohio. Paul: NASA Glen has expertise in aeronautics, space power systems, space propulsion systems and in full up space mission design. As part of their education outreach efforts, we went there, traveled there... worked side by side with their engineers over the course of a week to come up with the Lunar Lion baseline mission concept. Narrator: The team was taken on tours of the massive facility, but soon got down to business in Research Analysis Center, home of the Compass Lab. Bilen SOT: The Compass Lab is really a rapid mission development lab. There's a rapid interchange of information when you are iterating a design. Say you put on a new communications payload. That might increase the amount of power that you need. So the power engineer needs to keep track of that. and know when you're going to be coming up on a hard limit. In terms of you have increased power there is suddenly more mass that you need. So all of these things are a iteration cycle. And if this is done in separate offices, across the campus there at NASA, or between the NASA facility and here at Penn State, that is going to take a long time to do. But by co-locating people there at the Compass Lab, we can run through that iteration cycle very, very quickly. By the end of the week you can have a viable mission concept like we did with the Lunar Lion. Narrator: The Compass Lab is a state of the art workspace where all the workstations are connected and monitored by a manager. As changes are made all participants can see how those changes effect the outcomes of other work teams. Keegan SOT: With any major project that we are working on like that, especially with a space industry project it is really crucial that you do have everyone in the same room and being able to interact in real time. Because there is always so much "give and take" between the different subsystems. When you are trying to come with a solidified design you need everyone there to do that "give and take". Narrator: And after the week was done, the Lunar Lion Team was able to leave the Glenn Research Center with more than just a general idea of what was to be done. Paul: And so what we were able to do by sending this team of faculty and students to the Compass Lab and leveraging the tools they had there to come up with a mission design, was to take the requirements of the X Prize and make sure that we came up with a system and mission that fit within the box that we've defined for ourselves in terms of overall cost, launch vehicle capability, system capability and time to build it. We came up with a simple design... we came up with a straightforward design that's going to meet the mission requirements to win that grand prize. Narrator: And beyond the invaluable educational assistance outreach provided by NASA, the student team members received an opportunity that not many college students get... the chance to collaborate side by side with a working NASA professional. Keegan SOT: It is encouraging to see the NASA workers with that expertise. Because it gives me confidence that when I get the experience over the years as an engineer that I can be at that point one day and have that amount of expertise. So, I think it is encouraging and humbling in a way to know that even as students we think that we learn so much here in class, but just to see how much more knowledge there really is to learn within the space industry. Narrator: For In Motion I'm Curt Parker.

Spacecraft

The Lunar Lion is the spacecraft currently being developed to reach the Moon. The craft is planned to be sent on a commercial launch vehicle which will send it into space and place it on a trajectory to the Moon. It is then expected to make a controlled descent to the lunar surface where it will transmit high-resolution photographic images and video to the mission operations center at Penn State. The craft will then take off and fly a short distance to a second landing site while streaming the event live.

Testing and Development

Phase 0

At the end of October 2013, the team successfully finished Phase 0, a series of tests that validated the rocket-testing procedure. The phase included the development of contingency plans, safety plans, and thorough rocket testing procedure. As part of this phase, full rocket firing was simulated and investigated. Test plans must meet the Environmental Health and Safety Standards.[4]

Phase 1

Phase 1 included testing of combustible liquid fuel, a NASA-provided pencil thruster, and custom thrusters developed at Penn State.[4]

Phase 2

The initial liquid bipropellant part of this phase was completed towards the end of summer 2014. The team characterized and tested hydrogen peroxide monopropellant thrusters. These were used on the first flight vehicle the team constructed, a prototype called Puma. Each of the four 100 lbf engines were characterized to generate a thrust profile which was used for Puma's flight testing. Puma was developed for constrained vertical flight, with guide cables restricting motion to a single axis. Static testing of Puma began during the summer of 2016, and a constrained flight test was conducted on October 22, 2016. Puma made its first flight to an altitude of 3.5 feet, soft landing under its own power.
