Unique Exchange of Equity

When I look back at the nexus of “The Pegasus Mission” Mark and I made a single decision that transformed the challenge into something grander than we initially imagined. Because we were working with real-time, open, and distributed systems coupled to IoT, we needed something compelling that placed an emphasis and reason to the participate in the technology. We did not want to trivialize the technology in any way, and that led to a focus on driving a unique user experience that people had never seen before. By focusing on the entertainment value and taking users to a place they could not travel, we could passively couple both research and technology. It is a unique exchange of equity between the mission team and the users. The users get an incredible experience they could not otherwise obtain, and we get to test the premise of the research and the technology while they do it. While we initially believed our thoughts were original, they were not. The concept was originated a long time ago by a great explorer, Jacques Cousteau.

Perhaps you may remember watching “The Undersea World of Jacques Cousteau” on television when you were much younger. The Cousteau team would travel to remote locations and explore the oceans. This was in a time where underwater filming requiring highly customized equipment and scuba diving was not something many people could do. In fact, Cousteau invented scuba diving with his aqualung. You probably cannot remember the name of single researcher onboard their ship, the Calypso, or any of the research they were doing…but you remember the marvel of undersea world shown to you for the first time. We were absolutely enthralled watching the Cousteau team take risks below the surface in order to gain an understanding of what was down there. The act of watching the television special enabled us to be drawn into a marvelous exchange of equity, because that research, that we cannot remember, would never have been possible without us watching it. Ultimately, we all benefited from our own participation because the Cousteau team help make our lives better through the understanding and research that they did in the oceans around the world. It was an ironic twist that we can in some way thank ourselves for making the oceans a better place.   Our mission to near space is fundamentally no different and depends on users watching flight through our Web Site or phone apps.

With less than 2 weeks away from the launch of Pegasus II, where we take you not down into the oceans, rather into the heavens 20 miles into the upper atmosphere. We will test live video onboard the craft for the first time to bring you a completely unique experience from three times higher than where commercial aircraft can travel. You will see the curvature of the earth, the edge of the atmosphere, and the blackness of space in real-time. Additionally, we will stream telemetry from the craft, and map of the showing the position of the craft and our chase vehicle, all in real-time. Finally, we will let you send a 40 character message to the craft in flight and get your personal message into the flight video record.

While the endeavor is not without risk and success is not a guarantee. Unlike a television special, we will be executing the mission live and I can guarantee will it not be “perfect”.  Innovation is an inherently a risky proposition and it takes a courageous team to live it out and challenge assumptions about what is possible…and attempt to bring you an unforgettable experience. We can only try our best and I believe that the having the fortitude to attempt what has not been done before is noble effort in itself.

Pegasus II Communications Architecture

A quick look at the communications architecture for Pegasus II.  Our 7lb payload of radios and sensors is generating a considerable amount of communications to various users and services.  Phone Apps, Web Site, Power BI, and Flight Ops at Mission Control all have user interfaces.  Additionally, we added SMS and email services to notify users to the flight launch and a few critical points during the flight.  We will store the telemetry as we receive it and make it publically available through DocDB.  The video (not shown) will be streamed from its own field gateway directly into Azure Media Services where you can see Pegasus’s eye-in-the-sky during the flight.

Also, we are likely to scratch the proposed Boulder, CO launch site due to several issues with winds. Currently, investigating Wyoming as a stronger candidate for a launch site.

Pegasus Mission – Prequel

It was 11/07/2014 when I sent an email to Mark Nichols, my partner in this adventure, which contained on the subject line “Must do this” and a link in the body of the message. About 5 minutes later a simple response, “Absolutely”. The Pegasus Mission was born, a real-time IOT experiment in the upper atmosphere with a high altitude balloon (HAB) as a delivery system.

The first days of imagining this experiment we documented a simple set of goals and technical objectives:

  • A photo of the curvature of the Earth, the edge of the atmosphere, and the blackness of space.
  • Real-time telemetry stream of metrological information and location.
  • Demonstrate real-time control over the in-flight craft.
  • Make others participants in the flight through real-time broadcasting of the telemetry.
  • Survive (implicit goal)

Pegasus is truly an intersection of STEM fields, where the “T” is only a part of the equation. There is a considerable amount of engineering involved to make it tangible, to make it fly, to recover the craft, and get communications with the craft in real-time (milliseconds). Mark knows devices and is a craftsman with mechanical things. He can design the electrical systems, the communications packages, and craft the payload and its mechanical devices. I would take care of the aeronautical engineering of the flight and the Operational Technology. We would cross multiple fields from electrical, mechanical, aeronautical, even civil engineering and coupling that with cloud services and an Operational Technology, Piraeus, truly on the frontiers boundaries of what is possible. AFAIK, the first real-time broadcast of IOT technology from the upper atmosphere of our planet.

You could put a payload on a high altitude balloon and with some tools on the Internet likely make it fly. However, you would not know what was going to happen. Its challenge rooted in the hostile environment of the upper atmosphere. We could cover the basics and understand the flight dynamics, but you cannot test something with plus 200mph wind velocities at minus 60 degrees Fahrenheit in your basement. We would have to do our best engineering, our best craftsmanship, and take our shot.

Mark and I were discussing mission parameters on the phone one day, when I laughed up the idea of releasing the delivery system and plummeting toward the surface of the Earth, only to deploy the parachute just above ground level. Mark said, “A HALO drop. Let’s do that”, to paraphrase. . I told Mark, “if you tell me that you can get that parachute out fast enough, then I am okay with it.” Hurling thousands of dollars of equipment toward the surface of the earth faster than a car can travel was spooky proposition, but compelling. We would go for it.

Complexity was high (probably too high) and time was short. We had until that last week of January 2015 to get Pegasus-1 ready. Only a few months from when we conjured up the experiment from our collective imaginations. Mark was spending nights designing the sensor package and craft, I was trying to work through the aeronautics and prep of Piraeus, our Operational Technology. Sensors, servos, radio transmission, control console, MiFi, Piraeus, and Web site all had to work together, it was serial reliability. If everything does not work, we would lose the craft.

We were constantly buying equipment, regulators, sensors, radio equipment, cameras, antennas, meteorological balloons, parachutes. Weight is the deciding the factor, and has weight began to increase, it got more complex and more equipment was shipped to us. Our “bag” of equipment for launch would weigh about 70 lbs to get the 4 lb payload airborne.

Time had run out and we had a week before the conference. We decided to try for a test flight the week before at a remote grass airfield in Kankakee, IL. Weather conditions were suboptimal, but within range of what we thought possible. There was much work to do, not only did Pegasus-1’s electronics have to work, we would need a software interface between the transmitter/receiver and Piraeus, running in Microsoft Azure. While Mark worked on the payload assembly and testing the electronics, I would work in the software interface. We had feverishly worked 19 hour days completing our respective tasks, but still did not have an integrated system. There were also the logistical considerations, getting the helium, FAA flight advisories, permission for a launch site, etc. It’s not a backyard type of experiment, you have to plan it in advance. Completely exhausted, we had missed our launch window for the test flight. The operation would now move from central Illinois to the conference in Seattle where we would perform our session, then try to fly the following day. The weather forecast was optimal for Othello, WA on 01/28/2015. We would attempt to resolve any remaining issues and get airborne in the treeless environment of eastern Washington State.

The Miracle of Pegasus-1

The Pegaus-1 Mission launch schedule 01/28/2015 from Othello, WA at 11AM PST and was delayed several hours. We eventually got airborne mid-afternoon. Several technical problems occurred, e.g. the Ham radio was not operational. This was the backup location system in case we lost the primary GPS, and now we were flying with only a single system to locate the craft. The tracking devices were a directional ground station and an omnidirectional mobile station that we used in the chase vehicle. The ground station had long theoretical range to maintain contact, while the mobile station was much shorter in range. Early in the flight the ground station, experienced some issues and lost contact with Pegasus-1. The shorter range mobile unit was all we had to maintain contact with Pegasus’s location. We had spent many hours trying to make sure we would have contact with Pegasus-1; otherwise we would lose her in a lonely field in a lonely place. Now we were hanging by a thread with only the primary GPS and the mobile unit. As Pegasus ascended and turned due East, the ground station came back online and we had 2 points of contact with the craft. Some relief, but still living only on primary GPS.

The telemetry stream was amazing as we could see the information streaming in every 2 seconds from Pegasus-1. The altitude on the GPS was not updating as fast as we expected, which also led to suspicions on the accuracy of the primary GPS. Was Pegasus-1 where we thought it was? The low hanging cloud layer gave us no visual on the craft, we just had to go with what we had. The ground units pushed the telemetry into Piraeus, our Operational Technology, where a Web site could instantly display not only the telemetry, but also the location of Pegasus-1 on Bing Map. Our chase team used the Bing Map updates to keep positioning and maintaining contact. This was very entertaining.

We were expected a turn to the West in the upper atmosphere, almost reversing the course that we had traveled. This occurred as expected with a slight WNW heading from the lower altitude E heading. We had purposely not expected to take Pegasus-1 to burst altitude, instead we intended to control the descent with a remote release of the delivery system. As we moved further to the West and slightly North the craft was tracking further from the main road, US HWY 26. Given that the altitude had reached mission objectives and that ruggedness of the side roads, we decided to release the balloon and begin the descent stage. Our descent was to be a HALO drop to about 1,000 meters above the surface of the earth where the main parachute would be deployed. Our tiny 12″ drogue chute would keep Pegasus-1 in a vertical position to maintain contact during the rapid descent, expected to take 10-13 minutes from the apex of the flight. We released the delivery system and began the descent stage dropping at 212mph from about 85,000 feet.

Only a few seconds later, at 75,000 feet, we lost primary GPS, but kept streaming the other telemetry data. The chase vehicle was positioned on a gravel road approximately 1.5 miles to the SE of Pegasus-1 when we lost GPS. Our strategy was to move either North of South to intercept, but without GPS and the low hanging cloud layer, we had to get a visual. Time had passed and we continued to look for the craft in the agricultural fields East of Othello, WA. It was going to get dark and we needed to back to launch site and pack up for the drive back to Seattle. We had lost Pegasus-1, but had proved the technology Piraeus, command and control, much of the craft design, and we did have the telemetry…but we didn’t have the video from the onboard GoPro camera or our craft. Now packed up and getting dark, we began the 3+ hour drive back to Seattle, disappointed without the recovery of the Pegasus-1.

Several days later I was reviewing the telemetry and noticed an abnormality. It appeared the primary GPS had come back online with only 30 seconds of flight time left. The chase team was scanning the horizon for signs of the craft when this occurred. We would not have noticed, nor expected it. Could Pegasus-1 have called for help at the last stages of flight? I considered this a remote possibility and began to check path, air pressure, and other telemetry to determine whether this “burp” of location information could possibly be valid. The location “burp” was in a direct line from where the GPS cut out at 75,000 feet and in the expected path. Careful analysis lead us to believe that Pegasus-1 was about 1.5 miles due North of where we had stopped the chase vehicle. The probability cone as only about 600 feet from the last location. Had we found where the craft actually rests?

Our excitement was high and Mark Nichols, my partner in this adventure, had decided to stay an extra day in Seattle and make the 250 mile drive back to the site and try to recover Pegasus-1. He called me and said he was standing on the spot, but no sign of the craft. He wandered through the fields for a time, then decided to drive a short distance to a nearby business to see if anyone had seen a UFO in the field. The business informed him that they knew nothing and he began his disappointing drive back to Seattle. Mark pulled out of the business toward the same point that he had started and noticed some orange out the left side of the automobile. He stopped. He saw some green, it looked like trash in a field. If the drogue parachute was orange and white, what could be green. The shroud lines of the main parachute!!! Mark approached and there it was. Pegasus-1 fully intact and only 800 feet from where we thought it to be. The Operational Technology, Piraeus, not only was critical to real-time flight operations and distributing to others to view, it also saved Pegasus-1’s dying breaths of GPS location.

We now have the telemetry and incredible video of the flight. We are compiling and condensing the video about this amazing story to release soon.

While Mark and I may have been the tip of the spear for the Pegasus Mission, nothing happens with the help and support of others. Our launch and chase team (Rohit Puri, and Gupreet Singh) and the unwavering help and support of Microsoft Research’s Orleans team that guided us for over a year in the construction of Piraeus, the Operational Technology that puts the real-time IOT into the Pegasus Mission. It takes a village, a village of dreamers and innovators.

My thoughts on innovation compiled > 1 year ago, what I believe … here

The Pegasus Mission

The Pegasus mission is all about experimentation and innovation and involves both a high altitude balloon (HAB) scientific payload and the “Internet of Things”, aka IOT.  The following are the mission goals and technical objectives.

Mission Goals
(1) In-flight telemetry
(2) A photo of the curvature of earth, edge of atmosphere, and blackness of space.

Technical Objectives
(1) Real-time telemetry
(2) Broadcast of telemetry
(3) Telemetry capture
(4) Real-time command and control

The idea behind Pegasus is to perform real-time IOT in the hostile environment of near space.  The definition of “real-time” requires a deadline and for this mission we set the bar at < 100ms from the edge of near space to an observer, e.g., a phone or Web site.  We will capture the telemetry in cloud storage accounts for later analysis, but allow the observers to participant in the experiment in anywhere in the world as it is happening.

(1) Ground speed in knots
(2) Heading – compass point of the direction the payload is traveling
(3) Camera Angle – compass point of the direction of the camera
(4) GPS – latitude and longitude of the payload
(5) Pressure – Barometric pressure of the atmosphere
(6) Internal Temp – Internal temperature of the payload
(7) External Temp – External temperature of the atmosphere
(8) Humidity – Atmospheric humidity
(9) Altitude – Altitude of the payload
(10) Signal Strength – Strength of transmitters
(11) Battery – The charge remaining in the battery
(12) Accelerometer – 3D force on the payload (x,y,z)

This is a total of 17 data points streaming every second from the payload.

Commands are used to communicate back to the payload to perform functions associated with cut-down (releasing the balloon tether from the payload to begin the descent stage) as well as parachute deployment commands.

The ascent stage is slightly over 1 hour for Pegasus-1, which should get to about 22,000 meters, which is enough to meet Pegasus-1 mission objectives.  During ascent we will be busy checking the systems for nominal condition.  More on this later.

The descent stage is all the drama Pegasus-1 makes a controlled HALO descent to 1,000 meters before deploying its main parachute.  The entire descent should take only 10-12 minutes.  It’s really “Fly or Die” time and the onboard and controls systems must work perfectly.

That is the summary for Pegasus-1 with more to follow on the aeronautics, payload, and operational technology that enables the real-time aspects of the mission.  Launch in 3 days from Koerner Aviation’s airfield in Kankakee, IL 01/19/2015.
