Remembering Adrian

From the InterPlanetary Networking Special Interest Group (IPNSIG)

Remembering Adrian

We hang on to the people who matter to us, as long as we can, and then we can’t hang on any longer and they’re gone. Adrian Hooke was a visionary, a romantic, a true believer, sometimes a tough adversary and always a loyal friend. Maybe most of all, for those of us who worked with him on making the Solar System Internet a reality, he was a tireless, resourceful, and endlessly enthusiastic leader. We will miss him.

Adrian was an admitted Space geek for 46 years. He worked on the Lunar Modules for Apollo 9, 10, 11, and 12, from 1966 to 1969. He was on the flight control teams for the Mariner 9 and 10 missions that visited Mars, Venus, and Mercury. He worked on Voyager and SEASAT, and in 1976-77 he spent a year at the European Space Agency helping with the Shuttle-SpaceLab program.

Out of his experience with these projects grew a deep understanding of the complexity of communicating with spacecraft and of the costs and risks inherent in reinventing vehicle command and telemetry procedures over and over again for every new mission. So from 1981 onward Adrian made it his business to improve the reliability and reduce the cost of flight mission communications by establishing sound standards.

He was well equipped for job he’d taken on. He was very smart, and he was highly articulate. In Adrian’s nature were steely determination and limitless energy, with not only a keen appreciation of human wackiness but also an equally keen ear – and not much patience – for pernicious nonsense.

In 1982 Adrian co-founded the international Consultative Committee for Space Data Systems. Within CCSDS, he was instrumental in the development of international standards for Packet Telemetry, Packet Telecommand, the Advanced Orbiting Systems protocols used for communication with the International Space Station, and the Space Communications Protocol Standards that improve Internet protocol performance over links to Earth-orbiting satellites.

All of this was prologue to the vision of a ubiquitous, cheap, and reliable Interplanetary Internet – as simple to use as the terrestrial Internet, but able to operate over the enormous distances between planets in the solar system – that captured his imagination in the late 1990s. Adrian organized the initial meeting of JPL, MITRE, and Sparta engineers with Vint Cerf at MCI, in February of 1998, that planted the seeds for what we would later call Delay-Tolerant Networking. He then spent the next fourteen years nurturing DTN: finding money to develop it, encouraging experiments to demonstrate it, and helping often-skeptical space programs to finally understand its importance. That work isn’t done yet, but without Adrian’s fierce commitment it might never have gotten started.

And there isn’t anyone quite like him to take over, now that he’s gone. The rest of us have just got to step up. In the end, Adrian finished the job in the only way he could: along with so much else, he left us an idea worth reaching for. We couldn’t hope for any more. Goodbye, Adrian, and thanks.

Adrian was the spark plug and engine that kept our growing team focused and productive. Never seeking recognition for himself, he worked tirelessly to keep the Interplanetary Network effort in the budget and on the radar screens of those whose support was needed. He was the master of PowerPoint with presentations that easily topped 25-50 MB and jammed images and information into exquisitely choreographed stories. His spreadsheets were paeans of persuasion for those whose budgets needed to include support for IPN. Adrian had a wacky side too – his sense of the ironic and the ridiculous produced some of the weirdest and funniest URL pointers to obscure websites I have ever seen. I still laugh until the tears come every time I hear “The Bricklayer’s Lament” [http://www.youtube.com/watch?v=zZUJLO6lMhI].

We are grateful for all the support he and we received from his wife, Merle McKenzie, who worked with him at JPL and NASA. They made a remarkable team and her presence in our midst reinforced our determination to press on when things seemed dark, as she continues to do despite her personal loss.

Scott Burleigh’s beautiful requiem speaks for all of us who loved and worked with Adrian for many years. We will carry on, somehow, driven by the belief in the possibilities Adrian articulated so well and so convincingly.

Adrian has gone on ahead of us, as he did in life. Somewhere, somehow, in the fullness of time, I won’t be surprised to find him again, ready to put us all to work together on another project he’s prepared for us. So long, Adrian, and thanks for all the fish…

From Rich Miller, Jet Propulsion Laboratory, Retired


Merle,

Adrian was a very unique character (somehow I think you were well aware of that). His technical excellence and rare combination of detailed and big picture understanding always commanded respect in that wide audience.

I will highlight only two aspects which were a source of both admiration and amusement for me over all those aforementioned years.

Adrian was a master of presentations. His viewgraphs were always amazing and combined with his language skills always made his presentations the highest information density of anyone no matter the occasion. He also had an amazingly flexible throttle. He could have 10 viewgraphs left and the chairman say, "I know you were scheduled for 20 more minutes but the meeting is running late, can you finish in 5?"....and he would do it without leaving out a singe viewgraph or word. "One minute warning," with 3 viewgraphs left, one more click up on his speed and he would finish as requested still without dropping a word.

The second I will mention, which is related to his presentation skills, was his command of language. Adrian was an archetypical example of why the language the rest of us try to use should be called "English". His use of words and turn of phrase was a reminder of why the Masterpiece Theater drama's and comedies are such a delight. Even when Adrian criticized someone (even if it was you) you wanted to write it down to remember the cleverness and originality of it. An example I remember was a particularly eloquent diatribe of someone’s [at a Center] lack of competence. Unfortunately he had sent this as an email to the subject person with several on distribution. I replied to Adrian's email saying "although you are right about him" it was wrong to put such a thing in writing and particularly in a medium such as email which could so easily be recopied and spread. His email reply to my reprimand was short: "It is also a good practice to be careful with "Reply" verses "Reply all". To my horror his was right, I had accidentally used "Reply all" to the same distribution.

Lots of good memories of significant challenges, shared frustrations, and celebrated successes.

Merle, I was looking for my pictures of Adrian and finally came across the box containing these photos.  These pictures are from the Block Telemetry party at the LAB.  It was a Bar Mitzvah party (13 years after the writing) for the paper.  I hope to see you soon so we can give you our good wishes in person. 


From Ed Birrane, Johns Hopkins University


Hi. This is Ed Birrane, and I work at the Johns Hopkins University Applied Physics Lab (APL) and have supported, in some fashion, the DTN project for the past several years. We all had dinner together one evening in Darmstadt and we spoke briefly in January at JPL after your lunch with Vint. I had mentioned sending you an e-mail, and apologize for any delay.

While I only knew Adrian in a professional context, I was enormously fond of his personality, insight, and enthusiasm. I was looking forward to seeing him at the meetings at JPL in early January and so shocked and saddened to hear of his passing.

There were three things I wanted to communicate as you were collecting work information for Adrian: my sincere thanks for his championing of the DTN project/technology, a singular memory of him in Noordwijk, and how deeply I enjoyed, and miss, his manner.

 First, a thank you.

In early 2012 I drafted an e-mail thanking Adrian for his passionate drive in championing a transformational technology within NASA and recounting how it had a very large impact on my career and personal direction. I never sent that e-mail as I felt it inappropriate to send such a thing to someone who gives you money; there is always the chance the intent could be misconstrued.  I regret, now, deleting it instead of sending it. I want to pass on to you the gist of the e-mail and to at least get the "thank you" out there in some small way.


Several years ago I came to a personal conclusion that I needed to shift my career away from repetitive engineering tasks and towards strategic technology development; to be more thinker than typer. Around that time I joined the NASA DTN project. It was interesting technology: space and NASA and Internet rolled into one. The problems were (are!) technical, social, and political in nature. At the core of this team was Adrian - someone with a wild enthusiasm to envision a new technical reality and with a sharp (and humorous) intolerance of status-quoers and the occasional "radiohead". He was charismatic, effective, had a history of successes, and a wonderful wit. I love technology, but he made me love *this* technology and the context in which he wished it applied. His passion for this work was infectious and I am plodding through my PhD thesis in this area (with Vint and Keith Scott on my committee).

I owe Adrian a very big "thank you" for fighting for this project, for letting me/APL on it, and for keeping me/APL on it (and that was pretty tough to do sometimes).  I owe him a very big "thank you" for inspiring me not only on this technology, but with his energetic, holistic approach to realizing it. I learned lessons from Adrian I would not have learned from others, and I am grateful to him and for him.  While inspiring me is important to me, I have no presumption that it is important to others, so I also wanted to thank him for his generally inspiring persona. It is highly likely I am not the only life path he has influenced.

Second, a recollection.

A few years back we had a CCSDS meeting in Noordwijk at ESTEC.  My wife, Linda, came with me as she always wanted to see the tulip fields (or mud fields in the off-season...), The Hague, Amsterdam, Delft, and other areas. One evening was a CCSDS-sponsored dinner and Linda joined in.  Sitting at our table were several DTNers working to understand the value proposition of DTN.

As it happened, Linda sat next to Adrian and a few minutes into what was to become a multi-hour debate, Adrian checked out of the DTN conversation and spent the rest of the dinner chatting with us. He spent the time talking about living in Noordwijk, the strangeness of keeping up the bay window appearances, the snowstorms and medical emergencies, places to see.  He spent some time talking about his family and having lived in various places. It was a warm, personable and kind discussion which completely saved the evening for those not wishing to delve into a night of aerospace politics.  While a small kindness, we have carried that with us.  Linda was as shocked and saddened at the news of his passing as I; she sends her most sincere condolences.


Third, some humor.

Many of my e-mails with Adrian were technical in nature, or dealing with budgets, timeframes, statements of work, and such. Some e-mails included ventings that are probably best left un-forwarded. However, in going through my e-mail archive, I pulled out a few examples in our correspondences of my exposure to his directness and humor, which I miss very much.

On funding APL:
-------------------
> We are on Q1 fumes right now

Is that stuff legal in Maryland?

On religion:
-------------------
> I'm not a fan of the term "my illness", and don't mean to pry.  Not sure
> where you fall on the faith spectrum, but I've certainly said a small prayer
> or two for your health this past week. While admittedly unlikely, let me

Thanks Ed. No need to apologize - it has been my choice not to bore people with minute-by-minute details about my illness, so your catching me in the hospital was a natural consequence. I am home and doing fair to middling.

On the faith spectrum, I once went to a couple of Unitarian gatherings. Afterwards, we used to go out and burn question marks into people's lawns .... ;-)


On financial planning:
-------------------
> APL's contract through JPL ends on 2/29 and we are spending these last two
> weeks packaging up our deliverables, including the DTNMP RFC, and
> software check-ins.

Ed: sorry, I have been consumed with getting DTN budget, not spending it.

On NASA HQ:
-------------------
>Currently in disneyworld.

Do you mean that you are [at] NASA-HQ?

Thank you for the chance to pass along a few fond memories of Adrian.

-Ed
                                                





You might want to skip to the end of this one for the picture there.

Subject: IOAG Announcement: Commemorating Adrian Hooke's Contributions Though the CCSDS Hall of Fame

CCSDS Founder and Lifetime Leader Active in CCSDS 1982-2012


Adrian Hooke dedicated his career to advancing the abilities of our international space agencies to work together, through development of data/communications technology and standards that enable multinational missions and bring many other benefits to the aerospace industry. He is credited with initiating the coordination that would eventually bring CCSDS into existence, and with providing not only technical and management leadership, but also the conscience, heart and soul of CCSDS for the three decades of his CCSDS participation.


From 1966-1969 Adrian worked in US industry as a member of the Kennedy Space Center launch team for the Apollo 9, 10, 11 and 12 Lunar Modules. Joining JPL in 1969, he was a member of the flight control teams for the Mariner 9 and 10 missions to Mars, Venus and Mercury. He worked on the Voyager onboard data system and led the design of the SEASAT end-to-end data system. In 1976, he took a position with the European Space Agency working on the flight operations architecture for ESA’s role in the Shuttle-SpaceLab program. Rejoining JPL in 1977, he focused on the development of new technology in the area of standardized space data communications protocols.


During this early period, Adrian worked on the development new approaches for space data communications. In 1974, he co-authored a new technology study on “Block Telemetry”, which actually flew on a later mission. With Adrian’s help, this work was expanded within NASA in 1977 to a JPL/GSFC collaboration, the NASA End to End Data System (NEEDS). Then, in 1979, Adrian used contacts from his time in the European Space Agency (ESA) to evolve NEEDS to an international collaboration; the NASA/ESA Working Group (NEWG). The NEWG would pioneer international usage of the “Packet Telemetry” scheme, the foundational telemetry scheme that would later become the bread-and-butter of the Consultative Committee for Space Data Systems (CCSDS). By 1982, Adrian and NASA HQ had expanded the NEWG to include other agencies, and the CCSDS was officially formed. Over the next 30 years, Adrian would perform a multitude of CCSDS leadership roles both in the highly technical and management arenas. Adrian served as the “technical conscience” of CCSDS, working towards the interests of both NASA and the whole international community, and forging a groundbreaking path for multi-agency spaceflight missions.


Adrian also brokered the agreement between the International Standards Organization (ISO) and CCSDS which would put CCSDS standards on a “fast track” to become ISO standards, by designating the CCSDS organization as ISO Technical Committee 20 Subcommittee 13 “Space Data and Information Transfer Systems”. Adrian also chaired the US Technical Advisory Group 13 (USTAG13) which formulates the US inputs into ISO TC20/SC13.


On the technical side, Adrian was instrumental in developing the Space Communications Protocol Specifications (SCPS), which were precursors to the advanced Delay Tolerant Networking (DTN) protocols. He also provided a major technical leadership and Project Management roles for both DTN and Data Standards within NASA. At the peak of his leadership, Adrian served as the chairman of the CCSDS Engineering Steering Group (CESG) and as the NASA Project Lead and Technical Lead for the Data Standards project and DTN project in the Space Communications and Navigation office at NASA Headquarters.


Managing CCSDS overall, Adrian executed innumerable innovative management strategies, such as reorganizing CCSDS (in 2000), modeling it after the successful Internet Engineering Task Force (IETF) processes. His technical vision and leadership drove the standards community as he executed and relentlessly promoted the adoption of standards by the international community. As of this writing, the adoption of CCSDS standards by over 600 missions, both US and international, is a testament to the broad influence that Adrian’s work has had on humankind’s spaceflight programs. Adrian’s leadership, vision, wit and wisdom was a principal driver for the first three decades of CCSDS accomplishments. Adrian will be sorely missed by his NASA and international friends and colleagues.


Adrian held a B.Sc. (Honours) in Electronic and Electrical Engineering from the University of Birmingham, England. He was registered as a Chartered Engineer (C.Eng.) with the IEE in London and as a European Engineer (Eur. Ing.) with FEANI in Paris. He was awarded two NASA Exceptional Service Medals and the NASA Exceptional Achievement Medal. He was also awarded a one-of-a-kind special CCSDS award for his lifetime leadership, in April 2012.

From Stephen Farrell, Trinity College Dublin

Hi Merle,

I just head the sad news today about Adrian. I've worked at a distance with him on and off for the last decade and he'll be sorely missed in the DTN community. His leadership
in this area was hugely significant.

And aside from work, I'll personally miss his occasional snarky but hilarious emails - I got a bunch of laughs out of them over the years, even the ones that took the piss
out of the Irish:-)

My deepest sympathies,
Stephen Farrell

Trinity College Dublin,
co-chair of the IRTF DTN research group

From Philippe Schoonejans, ESA

Dear Madam (dear Merle),

Via our NASA contacts I got your email address and heard that you would be
interested to hear from Adrian's colleagues around the world.

In the European Space Agency ESA, we have a cooperation with NASA on robotics
tele-operation and telecommunication, which is called METERON. Adrian was the
champion on the NASA side for development of new communications techniques
like DTN, so we had a lot to deal with him. Ad what can I say other than that we will thoroughly miss him. His dedication and enthusiasm was always incredible, and he was a real ally for us. Adrian also told me that long ago he has been working in Estec, just
before I came to Noordwijk. So perhaps ESA was special for him too.

Of course this email can not do anything to lessen your loss, but maybe it is nice to know that also on the other side of the Atlantic there were many people who appreciated Adrian and enjoyed working with him.

On behalf of the METERON team in ESA (Noordwijk Netherlands and Darmstad, Germany), I would want to pass our condolences, deepest sympathy and best
wishes to you and Adrian's other loved ones.

Kind regards,
Philippe Schoonejans, Head of Robotics, Human Spaceflight and Operations, ESA
(METERON project manager)

From Chris Taylor, Area Director of CCSDS’s Spacecraft Onboard Interfaces Area


Dear Merle, I write with sadness to hear of Adrian. I have worked with him
for over 20 years and was privileged to call him a friend. We worked together
on many standards over the years and although we did not always agree, we
always came to an amicable agreement in the end. His knowledge was vast and I
was always so impressed by how he kept a handle on so many things at once.

He was the NASA standards Programme and he will be missed by all of us in
Europe.

My sincere condolences to you,

Chris Taylor

Dear Mrs. Merle,

The news of Adrian's departure has left me in shock and grief. I saw him last April here in Darmstadt where he had his normal good temper and did not hesitate to make jokes of the Mayor on his bicycle. He looked OK at that time.

I have known Adrian for more than 10 years, since my participation to CCSDS started. Although we met only twice per year, we would not have to wait longer than a couple of weeks for exchanging business related emails.


Adrian was CCSDS. He was very competent but also reasonable and able to work out compromises between both sides of the Atlantic. I called on him several times to sort out very distant positions and he never failed. He would find a solution to any non-conventional request we might have had.


I will sorely miss him.

Sincerely,
Enrico


From Dave Israel, NASA Goddard Space Flight Center

Merle,

At first I thought sending a sympathy e-mail was inappropriate, but I realized that sending this message over a network is especially appropriate.  I thought about how to send it over a space-link, but couldn’t come up with a plan I could implement immediately…

 I was glad to see you briefly yesterday, when you stopped by the DTN meeting.  That meeting would not have been happening, in fact the whole DTN effort would not be happening, if not for Adrian’s talents, passion, and persistence.  I’m so thankful that I had the opportunity to meet and work with him.  I learned a great deal from him about all of the non-technical aspects relating to bringing technologies, standards, and organizations into existence and keeping them going through all of the challenges.  I viewed him as a highly respected and admired colleague and mentor, but, perhaps, more importantly a friend and kindred spirit.  I will greatly miss the opportunities to meet with him, witness his one-of-a-kind presentations, receive his e-mails, and hear his unique turns of phrase and characterizations.

He has created a great legacy and I’m certain that me and many others are even more committed now to keeping it going.

Deepest Sympathies,

Dave Israel  


From Gian Paolo Calzolari, European Space Agency ESA/ESOC

Dear Merle,


The sad news about Adrian did shock all of us.

I have been knowing Adrian since 1996 when I joined CCSDS and he has always been a clear guidance and example for me as (at that time) a young engineer.


Going ahead in the years I think I had the invaluable opportunity for appreciating not only Adrian's technical excellence and vision but also his exquisite politeness, friendly manners and honesty.

I will miss greatly Adrian example and guidance in the CCSDS and thinking about the sorrow this sad news caused to me, I guess that the suffering for Adrian's family shall really be something of unthinkable magnitude.

Please accept - together with your family -  my deepest condolences for this mourning.

From Jane Marquart (GSFC-5820)


Dear Merle,


I thought I would wait a bit before sending you this note as I am sure you received so many e-mails after the news of Adrian's passing.  I met Adrian about 10 years ago when I become involved in the Standards program at Goddard and eventually was the GSFC rep as well as the lead for the 'beloved' DTN project.  You and I have met briefly several times, most recently in January when you were at JPL to meet Vint and were gracious enough to stop by the DTN working group meeting to say hello.  

That took so much courage,  I wanted to jump up and give you a big hug but I guessed that wasn't the proper venue!  But it was a nice gesture and enabled those of us that hadn't seen Adrian in quite a while to digest the news just a little bit more, so thank you.


I learned so much from Adrian, as the Standards program was my first foray into the international arena (as well as working with HQ).  Diplomacy and tenacity are two words that come to mind quickly when I recall Adrian in action.  Unlike many in the DTN group, my relationship with Adrian was primarily professional, as he didn't talk much about his personal life.  We'd chat about your place in Colorado (I have a house in South Carolina), and topics along those lines.  However, two things I will always remember that I wanted to share with you.  First, was the smile on his face when he spoke of being a grandfather (and actually babysat, right?).  So proud he was!  And second, was an e-mail I received announcing that your book had been published.  Again, seemed like a very exciting event for him.   For some reason, these just brought a smile to my face, maybe because after so many years of the 'professional' Adrian, I got a glimpse of the man who loved his family so much.


We'll all miss him tremendously.  


Sincerely,

Jane Marquart




From Larry Freudinger, NASA Dryden Flight Research Center

Merle:

Thank you so much for calling today – I pray that you are coping well.  I spent some time this evening reviewing the tributes on the Internet to Adrian, and I cried.  Many tributes out there assert that Adrian touched many lives.  My life is one of them.

 I first met Adrian at his “Internets in Emerging Mixed Environments” workshop.  I was neither a space guy nor a protocol guy, but I did share with this audience an understanding of the latent value in reliable vehicular network communications.  My interest was and is networking amongst aircraft.

 So there I was, waving my arms about and pontificating about how great life would be once we got network access to and from instrumentation networks on aircraft.

 After I finished my talk, this guy who I later discovered to be Adrian raises his hand and asks “Whose job is it to deliver that networking service for aircraft?” I replied with something to the effect of “you guys, I think”.

 If a technology gap could make a sound, it would be the silence that followed my reply.  We all listened to the silence and then I said “Oh.  We have a long way to go, don’t we?”

 I suppose I became one of many that Adrian took under his wing or was otherwise nudged by him in the right direction.  Over the next few years we successfully helped lobby for investments to develop telemetry networks in the aircraft testing world.  Then he asked me to be his technical chairman for the International Telemetering Conference which, quite frankly, was a watershed event in my career.  He was a fantastic mentor; a sage with a brilliant, quick, and often acerbic wit that I simply wish I had.

 We all know his work is incomplete, and we continue to strive for the vision which is now officially passed on to us, his heirs. 

 With Deep Sympathy and Best Regards

Larry Freudinger
