Test Day: Roles and Responsibilities

By Morpheus Ops Lead, Ian Young

Test days are obviously a busy time for the Morpheus team. This blog is to give all of you some insight into who the players are. In a future blog we’ll bring you a narrative of a test day.  

Who makes up the team and what their roles & responsibility are on the day of a test.

Flight Manager (FM) – The Flight Manager has overall responsibility of the test. This is the position that represents project management, usually either the Project or Deputy Project manager. The FM coordinates any external interfaces needed on test day. They monitor the day’s activities and give the final Go/No-Go for the test.  

Test Conductor (TC) – This position is in charge of all the test day operations. The TC focuses on overall vehicle and crew safety, while integrating operations between the various control disciplines and the pad crew. TC also performs all the voice communications between the control center and pad crew. The position can be likened to the Flight Director in the Shuttle or Station mission control room.

Operator – Assists TC in the day’s operations, and helps ensure all steps are completed as required in the test procedures. The Operator sends all commands to the vehicle leading up to and including the start of the ignition sequence. The Operator also develops the day of flight procedures used by the team. 

Range Safety Officer (RSO) – Staffed by a member of the test safety group from JSC, the RSO has ultimate responsibility that Morpheus stays inside the range boundaries defined at KSC. Should the RSO feel the vehicle poses a threat to any personnel they have the ability to terminate the flight via the independent Thrust Termination System (TTS). The RSO has the authority to terminate the test independent of the operations team at any point they deem necessary.

Test Area Manager (TAM) – The TAM is Morpheus’ liaison to KSC. On test days the TAM clears the SLF air space, and coordinates with the NASA Air Traffic Control tower. The TAM also coordinates other KSC operations, such as crane riggers and truck operators for the cryogenic tankers.

Guidance, Navigation, & Control (GNC) – The GNC console is in charge of designing the day’s trajectory as well as the sensors such as GPS and Inertial Measurement Units (IMU) that keep the vehicle headed in the right direction. The trajectory is developed several days ahead of time so that many simulations can verify the correct parameters are set on the day of flight. On the day of flight the GNC makes final tweaks to the plan to account for test day variability like the actual prop load and the winds of the day. The GNC console must also monitor the GNC sensors for anomalous behavior and to ensure they are properly initialized prior to flight.

Propulsion (Prop) – The Prop console is responsible for all components related to the propulsion systems of Morpheus. This includes propellant tanks, main engine, Reaction Control System (RCS), and feed systems. Based on the trajectory design of the day the Prop console will calculate the propellant load of Liquid Oxygen (LOX) and Liquid Methane. Their calculations have to include main engine run-time, boil-off, and reserve. During the flight Prop monitors the main engine and RCS thrusters for correct performance.

Avionics and Power Systems (APS) – APS monitors the flight computer and power systems. Morpheus has flight battery system that must be verified prior to flight. There are a number of electrical systems that must be monitored throughout the day to ensure a successful flight.

ALHAT – When the Autonomous Laser Hazardous Avoidance Technology (ALHAT) package is installed on the vehicle, this position monitors the health of the three ALHAT sensors (Doppler Lidar, Laser Altimeter, and Hazard Detection System)

Ground Data Systems (GDS) – The control center has multiple workstations the operators use for command and telemetry and these are maintained by the GDS. GDS is staffed by the Flight Software (FSW) group and are in charge of both the ground systems software and the on-board flight software.

Morpheus Comm – These folks are responsible for the command and telemetry radios that relay Morpheus data back to the control center, along with the infrastructure that goes along with it. They also set up many of the cameras that are used for situational awareness inside the control center, as well as streamed out to our live audience.

Pad Crew: There are a number of Pad Crew that prepare the vehicle for test flight.
  • PAD 1 – PAD 1 coordinates all pad activity. Throughout the day the vehicle is put through functional checks, filled with propellants, leak checked, and put into final preparations. There are a number of personnel that help accomplish these tasks, including crane riggers, cryo operators, and other Morpheus personnel.
  • PAD 2 – Morpheus personnel who assist with propellant loading and leak checks.  
  • PAD 3 – This position operates all the cryogenic tankers for propellant loading.
  • Structures – The structures representative assists the pad crew with items that fall under their responsibility, such as launch stands and tether configurations.

Greatness on the Horizon

A note from Jenny Devolites, SE&I Lead for Morpheus, after a successful Free Flight Campaign in December...

As everyone who follows Morpheus knows, our first Morpheus “Campaign Zero” free flight test campaign at Kennedy Space Center in 2012 ended with a spectacular vehicle crash, after 26 successful static hot fire and tethered tests. Shortly after the crash, our Project Manager, Jon Olansen, gathered the sad but resolute team at the KSC hazard field landing pad and reiterated, “this is why we test.” We keep the dream, we learn from our failures, and we try again. NASA management, all the way to the top, understood the risks, and immediately turned us around to rebuild and fly again, because they understand the value of what we are trying to achieve. They can do this, because we are a low cost and lean project with an incredibly dedicated and competent team – a team who wants to build rockets and spacecraft and do whatever they can to help further human spaceflight and exploration.

Last week we had our first successful free flight of the “Bravo” vehicle. The flight was impressively on target with regard to the planned trajectory. All of the things we worried so much about – because of the Alpha vehicle crash and all of the testing since then – turned out to not be problems on that beautiful flight test day. There was definitely something redeeming for the team and the Agency -- to show that we could do this.

This past weekend, a bunch of the Morpheus team members went to KSC’s new “Atlantis” space shuttle orbiter visitor’s center. The exhibit is phenomenal, and found many of us with tears in our eyes as we revisited that amazing engineering endeavor coming to a close. One part of the historical film struck me – that the engineers who conceived of the space shuttle set out to make it a reusable spacecraft. Many rocket engines and spacecraft are single-use. Our little vertical test bed – our lander – is also designed to be reusable. But we don’t have thousands upon thousands of team members or a budget like that – we are a small project with less than 50 people (and that’s padding the number).

So just doing one successful free flight would be a career achievement – but two in one week is a tribute to the hard work and efforts by a team that has become like family. Today’s free flight went higher, and further, and faster – and it was 82 seconds of picture-perfect flying.

Last year after the crash, I remember vividly walking to the building next to our KSC vehicle hangar and seeing the Alpha vehicle wreckage for the first time up close. The crash itself had happened so fast that there was barely time to comprehend what happened. But there was the wreck, our wonderful creation, smashed and burned.

Today I waited outside in the sunshine (we’ve been lucky on weather this week here in Florida compared to much of the country) for the Bravo vehicle to be driven back to the hangar. I watched it roll in and marveled at the gift I have been given to be an aerospace engineer on a project such as this one. After today’s flight test we will spend a couple of days inspecting the systems and putting away all of the ground support equipment to get it ready for Campaign One in January, where we will fly increasingly challenging flight trajectories with our prototype lander vehicle.

And So We Begin Again

The roar of a 5,000lb rocket engine has returned to the Johnson Space Center. The Morpheus team has completed the build-up of our “Bravo” vehicle, conducted numerous integrated tests, and has now stepped into our flight test program. We are picking up where we left off – in fact we never stopped working. We have completed our first major milestone in conducting a 50-second static hot fire of the main engine in the vehicle, including simultaneous demonstration of thrust vector control (TVC) and integrated methane reaction control system (RCS) jet firings. Thrust vector control is used to balance and fly the vehicle, while the RCS jets are used to keep the vehicle pointed in the correct direction. We will step into dynamic tethered flights soon, in preparation for our return to KSC this summer.

The knowledge and insight we gained over the 27 test firings of the previous vehicle are fully incorporated into the testing we’re beginning now. Although a hardware failure led to the loss of the original vehicle last August, the failure and our internal investigation gave us valuable insight into areas that needed improvement. The vehicle may look largely the same as the previous version, but there are numerous changes that have been incorporated.  We have now implemented 70 different upgrades to the vehicle and ground systems to both address potential contributors to the test failure, and also to improve operability and maintainability.

Hard at Work

The Morpheus team has been hard at work preparing for this year’s series of tests and building the new Morpheus 1.5B and 1.5C vehicles.  We have been busy assembling the vehicle structures, wiring in all of our sensors, running integrated tests, continuing engine firings at Stennis Space Center, and more.

The Morpheus and ALHAT teams are now a combined team, which enables a more integrated series of tests as we prepare for future flight tests.  One of these integrated tests took place at Kennedy Space Center in December.  We used a Langley Research Center Huey helicopter as a stand-in for Morpheus.  We mounted the ALHAT sensors under the belly of the helicopter pointed in the direction of the helicopter motion.  Other components such as sensor electronics, Morpheus flight computer, real-time communications equipment and support hardware were placed in the passenger/cargo area.  This allowed both onboard and ground support teams to monitor progress in real-time.  The helicopter was  flown repeatedly on Morpheus-type trajectories towards the 
hazard field. 

Moving Forward, Not Starting Over

"A ship in harbor is safe, but that is not what ships are built for."

-John Augustus Shedd

On Thursday we made our second free flight attempt with the Morpheus prototype vehicle.  As you can see in the video below, shortly after liftoff we experienced a hardware failure and lost the vehicle.  The root cause is still under investigation,  but what we do know is that at the start of  ascent we lost data from the Inertial Measurement Unit (IMU) that supplies navigation updates to the flight computer.  Without this measurement the vehicle is blind and does not know which way it is pointing or accelerating.  Since this data is needed to maintain stable flight, the vehicle could not determine which way was up and began to tumble and  impacted the ground about 50 feet from the launch site.  No one was injured, no property was damaged besides the vehicle and we have been able to recover significant data, which will give us greater insight into the source of the problem.

We have said it before and will continue to say, this is why we test.  We have already learned a lot from this test and will continue to learn as we recover data and evaluate the hardware.   No test article should be too precious to lose.  A spare vehicle was planned from the start and is just a few months away from completion.  The basic development approach is to quickly build, test and redesign the hardware to achieve many design cycles and maturity before building flight articles.

Tether Test 20: First KSC Flight

The Morpheus team successfully flew our first tether test at Kennedy Space Center on Friday August 3rd.  The objectives for this flight, along with the dry and wet runs earlier in the week, were to verify all systems were in good working order after shipping from Johnson Space Center in July and to allow the new KSC support team an opportunity to move through flight procedures.

After looking over the data over the weekend and coming together for a Test Readiness Review, our Project Manager, Jon Olansen, approved our first ever free flight for August 7th.  This will be the first time we will fly the vehicle without a crane attached.  The crane was used in previous tests as a safety mechanism to allow each subsystem to safely tune their individual systems for a smooth stable flight.

Testing Begins at KSC

NASA's Project Morpheus lander is moving one step closer to achieving autonomous flight and landing. After undergoing testing at Johnson Space Center in Houston for nearly a year, Morpheus arrived at the agency's Kennedy Space Center in Florida on July 27 to begin about three months of tests.

Dr. Jon Olansen is the Morpheus project manager at Johnson. He said a small, dedicated team in Houston completed substantial work to design, develop, integrate and test the Morpheus prototype lander.

"We completed the fundamental testing needed to characterize vehicle performance while tethered at JSC," Olansen said. "Now it's time to move on to the next phase of the project where we fly the vehicle autonomously in free flight."

Olansen said the testing at Kennedy will continually expand the flight envelope until they can fully simulate the final approach and landing phases of a planetary surface entry.
