50 Years After One Small Step for a Man

By Dave Nordling, Secretary, Reaction Research Society


It was a half century ago today that mankind landed on the Moon. This event has had an impact on both generations present to witness this landmark event and the generations born afterward, such as myself. The Apollo 11 moon landing was a daring extension of an aggressive program that was progressively built from the dawn of the space age with abundant resources, acceptance of risk and political will never seen before (and never since). The herculean task set by the late President Kennedy in 1961 of landing a man on the moon and safely returning him to Earth by the end of the decade (1970) was fulfilled on July 24, 1969.

It was only eight years before that time when manned spaceflight began with the humble beginnings of riding a derivative of an intercontinental ballistic missile (ICBM) into low earth orbit scraping the bounds of the upper atmosphere. The journey was fulfilled with the enormous 6,540,000 lbm tower of three stages of the Saturn V vehicle filled with kerosene, liquid hydrogen and liquid oxygen that pushed three brave men into a new sphere of influence of the Earth’s closest celestial body just three days away. New systems and new rocket motors were built from scratch and flown in less than a decade. The massive Saturn V rocket could throw an unprecedented 107,100 lbm to trans-lunar injection (TLI) orbit. No other past or operational launch vehicle has surpassed this ability to this very day.

The Saturn V leaves its pad with a thrust of over 7,500,000 lbf.

Looking back, landing a man on the lunar surface appears simple and almost certain. But to those watching from their black and white televisions across the country and to the men and women behind the launch consoles, all of the Apollo missions were truly audacious with the looming deadline, a Cold War rival busy at work to maintain their leadership in space and an ever-present risk for tragedy at every step. Lives were lost, sacrifices were made and the goal remained steadfast. Excellence was demanded from hundreds of thousands of technical professionals, suppliers, shop workers, clerks and everyday people and was delivered such that two astronauts could walk on a foreign world opening the door to our species visiting a place beyond our blue Earth.

Skipping along the lunar surface getting work done. Beyond the human experience and reflection, this was an expedition filled with experiments to extend human knowledge.

At this 50th anniversary, it is interesting to reflect on what has happened since. After six more Apollo flights with five resulting in 10 more Americans walking, even driving over the lunar surface, the program came to an end under the Nixon Administration’s budget cuts. No other nation, including our own, has returned. It is probably due to this fact alone that more and more people begin to doubt whether the moon landing was ever real.

Also, it is the opinion of this author that because the Soviet Union’s then-secret moon program failed to place a cosmonaut into lunar orbit with their massive N-1 rocket, let alone a successful landing on the lunar surface, that our country saw fit to halt the progress of Apollo and turn our back on the Moon for five decades. I can only imagine how history would be different if the any of the four Soviet launches of the N-1 from February 1969 to November of 1972 had been a success.

The first man on the moon, Neil Armstrong, has passed away just a little less than seven years ago. Buzz Aldrin and Michael Collins remain as living historical witnesses, but in time, they too will pass on. NASA has a huge discontinuity in their chronology of exploration after the Apollo and Skylab program’s success. A long period of quiet then the Shuttle followed by eight years of paying the Russians for rides to the International Space Station (ISS) from Russia is all that remains. Our unmanned program has continued with ever more impressive returns as we learned about the moon, Mars and places throughout in the solar system, but our manned space program remains at a stand-still.

The legacy of Apollo has been more of historical legend and pride than any tangible progress eclipsing this feat of human achievement. The Space Shuttle program and its nearly four decades of life brought us the historical achievement of the first American woman in space, the first African-American in space, the launch of the Hubble Space Telescope, the first visit to a Russian space station, Mir, the first Russian cosmonaut to fly on an American space vessel, and of course the multi-year construction of the ISS celebrating its third decade of operation even after the Shuttle’s retirement. There are many people who feel that the Shuttle program failed its basic promise of routine access to space and certainly to fulfill the loftier goals of men reaching beyond low Earth orbit.

Since the days of Apollo, there have been new discoveries about the Moon. Thanks to the Lunar Reconnaissance Orbiter (LRO) launched in 2009, the Apollo launch sites have been seen in higher detail.

The Indian ISRO Chandrayaan-1 lunar orbiter, the Japanese Kaguya lunar orbiter and the American LRO have each found evidence of lunar lava tubes and “moon caves” in several places along the lunar surface which offers a tantalizing possibility of a ready-made shelter for future manned exploration.

The discovery of water ice in the permanent shadow in craters at the Moon’s poles starting from the Soviet Luna 24 probe to the ISRO Chandrayaan-1 orbiter provided strong evidence of an important resource awaiting future lunar explorers. .

Most recently, on January 3 of this year, the Chinese with the Chang’e 4 have soft-landed a rover (Yutu-2) on the far side of the Moon, a first for any nation.

With the end of the Space Shuttle program in 2011, planned since the Columbia disaster of 2003, the Constellation program, later renamed the Space Launch System (SLS) was built and extended from legacy technologies with years of flight experience.
At this moment in time, NASA has redoubled its commitment to returning people to the surface of the moon in just five years from now, 2024. It is possible this goal can be realized, but there are abundant reasons to be skeptical.

Technology is no longer the perceived barrier to finding our way back to the Moon. The ability of any government or administration to muster the cohesive, sustained political will and necessary funding to build and fly the SLS program to put men back on the moon is the question that remains unanswered. More so, will we have the fortitude to recover from failures should they occur and surmount them to make a permanent colony as was envisioned for after Apollo? To date, my generation has waited in vain on the many promises from NASA to deliver something of the magnitude of Apollo.

There is no shortage of passionate, intelligent people in this world. Many share the vision of mankind becoming an interplanetary species. Our art and culture have been permanently changed from seeing the whole of our world as a small blue marble against the enormous blackness of space. The true legacy of Apollo is the inspiration that was given to this nation’s people and any nation seeking to find pride in their abilities to put their citizens in space. Regardless of what may come in the next few years with NASA, the dream is alive with the people of the Earth to be explorers. To move beyond dreams is what will extend mankind to the Moon and beyond.


August 2018 meeting

The Reaction Research Society (RRS) held it’s monthly meeting on August 10, 2018 at the Ken Nakaoka Community Center. We were very well attended with four new people including returning member, Jim French. I was unable to attend the meeting, but other council members gave me their notes.

The RRS meeting got a late start at 8:00pm. (Our starting time is supposed to be 7:30pm.) The agenda items were not covered in order, but the list of topics to be covered were as follows:

[1]
This was to be a discussion of the 2018-07-21 launch event that the RRS held at the MTA with LAPD CSP and the student group at Watts. The event was successful with both the student alpha launches and a few RRS member alphas with payloads. The event was summarized in a previous article. A few things could have been done better which will make future events go more smoothly.

[+] A single, simpler briefing to the kids would have been more effective. The kids in the student classes do pay attention at the events (which is great) but the RRS is giving a lot of redundant information and a more concise presentation delivered by only the pyro-op will be far better than having three people talking at the same time.

[+] Also, every person conducting a launch or hot-firing at the MTA must submit a detailed proposal to the pyro-op for review at least a week in advance and gain the RRS and pyro-op’s approval PRIOR to coming to the event. The RRS used to be even more stringent on this requirement. The use of the RRS standard record form is required to be filled out by the experimenter for review by the pyro-op. The RRS requires advance preparation and there is no reason why this can not be done by all participants.

In recent times, our pyro-ops have been very casual about this requirement and have been kind enough to review things on the spot, but this was always at the pyro-op’s discretion. The pyro-op is the single and solo authority for what is and isn’t done at the launch event. The pyro-op should be the most informed individual about what is going to be attempted at the MTA.

The RRS has a Standard Record Form available on this website under the Membership tab of the Homepage and under the subheading of Forms. This downloadable document gives members a basic framework for the detailed information they must provide to the pyro-op describing their project and its goals. The RRS encourages members to present their proposed projects at the meetings and be very detailed in any reports submitted to the pyro-op and RRS president. The RRS wishes to keep good records to benefit the society and future projects.

RRS – Membership / Forms / Standard Record Form

[+] In future events where we have the student launch event conducted first, we should not plan nor conduct any events before the student launch. Getting back to an earlier point, having launch and hot-fire events declared, reviewed and scheduled days in advance will help make RRS events go more smoothly and safely. Years of experience at the MTA has shown that tasks ALWAYS take longer than planned and too much waiting can make coordination of large groups unnecessarily difficult. Therefore, having our coordinated events go off first without distractions from other planned activities will make it easier for our pyro-ops to conduct their duties and make our participants be more organized in their projects.

[+] The extreme heat of mid-July made it very difficult to conduct operations but having the motorized cart to shuttle the pyro-ops to and from the launch site made a critical difference. Bringing ice in the summer is a necessity. Having everyone well prepared for the hot weather continues to be the best advice.

Chris Kobel who is a member of Rocketry Organization of California (ROC) shared some advice for pyrotechnic operators (pyro-op). Chris has been a pyro-op for over 10 years and is pretty active with amateur rocketry. Safety was the primary emphasis of his presentation. He also mentioned a key point of contact at the Office of the State Fire Marshall (OSFM) of California, Tom Campbell. Mr. Campbell is very important authority at the California State Fire Marshall’s office who can answer important questions. Chris and the other pyro-op members at ROC were also willing to counsel RRS members interested in becoming pyro-op’s.

The RRS was glad to have Chris give our membership a wealth of information. We look forward to working more with Chris and ROC in the near future as the RRS is expanding our roster of pyro-ops for our growing events.

[3]
Osvaldo’s flight telemetry from his alpha flight on 2018-07-21 was briefly mentioned at the meeting. It was good that the flight was successful that data was taken. Given the time constraints, he’ll give more details at the next month’s meeting.

[4]
Progress on the RRS alpha parachute systems and future attempts was to be detailed by both Osvaldo and Larry who each attempted a unique recovery system built into the small confines of the alpha payload tube. Again, insufficient time was available at this meeting and this event can move to next month.

[5]
Sam Austin gave a presentation of MIT’s solid rocket launch and his upcoming liquid rocket hot-fire. Sam is here in Los Angeles for the summer on his internship, but managed to find time to launch his rocket from the FAR site on the same day the RRS held our launch event on 2018-07-21. The MIT team’s custom-built solid rocket motor (O4000) made from scratch reached an altitude of 33,132 feet as confirmed by dual altimeters. The vehicle weighed 121 lbm at liftoff and reached a peak velocity of Mach 1.8.

Sam described a rough order of operations for their solid rocket grain making process and detailed their recovery. The rocket touched down safely 2 miles away and was fully recovered. The MIT team was elated and attributes their successful launch to careful design, many hours of testing that went into every component. The RRS is happy for MIT’s success and hopes they will test at the MTA with their next rocket.

[6]
There will be a liquid rocket hot fire testing on August 18th at both the Friends of Amateur Rocketry (FAR) site and the RRS MTA. Sam Austin has been working on his liquid rocket motor to test at FAR, next door to the RRS MTA site. Richard Garcia has built a small liquid motor for what could become the RRS standard liquid rocket design. Our two members have agreed to share resources and the hot fire events will take place on 2018-08-18.

Both projects will use a nitrogen K-bottle as their pressurization source and will share a liquid oxygen dewar to provide the oxidizer to both of their engines. Richard’s and Sam’s liquid rocket motors will use kerosene as a fuel. Richard’s design is a 1000-lbf thrust design with an assumed chamber pressure of 300 psig.

Sam and Richard have put a lot of work into these projects and we hope they have success. I plan to go out there to help document the event for a new posting to come shortly after.

[7]
The meeting was to discuss upcoming RRS launch events including the next one with LAPD. Frank has said that the next event with the LAPD CSP will be with the Boys and Girls Club. LAPD CSP is also working on setting up another school group in Watts for an RRS event. Specific dates were not yet set, but that information will be coming soon. We will post announcements of forthcoming launch events in the “Forum” section of this webpage.

[8]
RRS Instagram and YouTube account guidelines have been generated by RRS treasurer, Chris Lujan, and are now being reviewed by the RRS executive council. The idea of creating an RRS media manager position was proposed and accepted by the council. The RRS is considering offering this new position to RRS members, Bill Janczewski and Alastair Martin, who both have put forth a great deal of excellent work for the society. The RRS executive council will vote soon to better our social media presence to help our outreach efforts and give our followers a better view into the society.

Richard Garcia shared access information with the executive council on the existing social media accounts that the RRS has including Facebook and YouTube.

The RRS executive council now has access to Instagram and will be sharing photos from events more easily and quickly with our public audience. I have already begun to load photos I’ve had from recent events. More of the RRS will be posting to Instagram very soon.

Subjects not on the agenda included:

[BONUS 1]
The RRS will start to hold special Saturday morning seminars for special topics that can be covered in more depth outside of our monthly meeting. These bi-monthly sessions will take some work to coordinate, but should allow more of our membership to enjoy the quality of talks that we have been privileged to enjoy. Jim French agreed to give the first of the RRS Saturday seminars at a date to be determined very soon. Jim was a member of the RRS 25 years ago and we’re happy he’s come back to join us.

James R. “Jim” French also has the distinction of being a rocket engineer for over 60 years and worked at TRW on the Apollo program. He wrote a book about his experiences called “Firing a Rocket”. This first RRS Saturday seminar will be a great presentation to start this series. The date will be announced soon.

[BONUS 2]
I have been able to get the top and bottom plates made for the RRS ballistic evaluation motor (BEM) which will be a key part of the SuperDosa project and the RRS having the ability to take accurate burn rate measurements at the MTA for future motors. I am thankful to Matt Moffitt of CNC Specialty Machining in Huntington Beach. I hope to have the cylinder piece in the RRS BEM machined soon. This will likely require lathe work. Osvaldo is also looking into getting this part made. It is my hope the RRS BEM can be completed by the next quarterly update of the SuperDosa project in October 2018.

Top and bottom plates for the RRS BEM just back from the mill.

I have heard that Jack Oswald is trying to get into testing his large solid motor with an improved design. The RRS may have more to present next month on this subject.

[BONUS 3]
I wanted to bring a special device I bought from Additive Aerospace called a fly-away rail guide. I was introduced to this device by David Reese of ROC. Although the RRS has a very effective box-type rail launcher at the MTA site which will remain our standard technique, I decided to attempt a new method of launching an alpha just to get a longer guided path on launch.

Additive Aerospace – fly-away rail guides

This device allows a rocket to be fired from a extruded aluminum rail launcher such as the one we have at the RRS MTA, but without having to permanently attach the round launch buttons to the rocket itself. A spring-loaded clampshell piece goes around the rocket with a launch button on either side such that the clamp is closed when the rocket is on the rail. As the rocket takes off, the fly-away rail guide goes with the rocket along the rail launcher until the buttons clear the rail and swing open releasing it from the rocket as it speeds away.

Fly-away rail guide from Additive Aerospace; custom-built for an RRS standard alpha rocket, shown in the open position.

These devices are intended for common model rockets of the standard metric sizes (38mm, 54mm, 76mm, 98mm). I had this rail guide customized to fit an RRS standard alpha rocket which is slightly smaller than the 38mm size at 1.25 inches in diameter. I hope to demonstrate the fly-away rail guide device with a loaded RRS alpha from the 12-foot rail launcher at the RRS at the next event. I will relay my findings to the society and back to Additive Aerospace who is very interested to see how their design can work with the RRS micrograin rockets.

[IN CLOSING}

Meeting adjourned at 9:16pm which isn’t too bad. Our hosts at the Ken Nakaoka Community Center continue to graciously allow us to finish up despite the center’s closing at 9:00pm on Fridays. The RRS should seek to better finish on time as the staff at the center need to go home.

The next meeting of the RRS will be held on September 14, 2018.

For questions, contact the RRS treasurer, Chris Lujan.
