HOW I GOT MY ORION

 

On July 8, 2011, I was at the Kennedy Space Center covering the final Space Shuttle launch, STS-135, for the Aero-News Network. By that time, president Obama’s cancellation of all NASA human spaceflight, had been over-ridden by the Congress and spaceflight engineers had begun to develop the Space Launch System, or SLS, in spite of Obama’s poison pen effort. I’d seen that coming and as the owner of a model rocket manufacturing company, Dr. Zooch Rockets, and thus designed a concept version of the SLS. It was slated to go into sales in just a few months. For that reason, I’d already constructed two prototypes and even test-flew one. The second prototype I packed up and took with me to STS-135 for display at my spot in the press building at KSC.

 Considering that STS-135 was end of the Shuttle program and the beginning of a “gap” between U.S. astronauts being launched aboard U.S. rockets- the event drew plenty of attention. In those days the press was always divided between the “hardcores” who actually know spaceflight and the “meatpuppets” who are simply reporters that some network assigned to cover the event. The meatpuppets normally just stand in front of a camera and read from a piece of paper. Arriving at STS-135 I was only in the press room long enough to say hello to some of the hardcores, plant my model of the SLS at the spot I claimed as mine, and head out to have a look around. Soon the meatpuppet storm began. In short order media from all over the world were squeezing into the press room or setting up shop, some doing so in assorted EZ-up tents outside. One of the hardcores looked around the room and she quietly said,

“I wish they’d all go away and just let us, who cover these things, cover it.”

Then she pointed with her finger toward individuals standing nearby, as if she were able to select people and said,

“You can stay, you can stay, you can stay…”

She pointed at me and paused for a second.

“Hey,” I quipped, “I was at X-Prize with you… I have cred’.”

“Yeah,” she smirked, “you can stay.”

Whew.


There was a carnival atmosphere around the open ground beyond the press building. NASA contractors large and small had set up display tents also large and small. One of the largest belonged to Lockheed Martin which was contracted to build the Orion spacecraft. I went in a chatted briefly about Orion with one of their people. I mentioned my model rocket company, and he said that his son was just getting into model rocketry.

 “I have something you may wanna see,” I said in the hope of perhaps gaining a new model rocket customer.


Dashing back to press building I fetched my SLS model and returned to the LockMart tent. He looked at it,

“I have someone who would be interested in this,” he said as he walked a short distance away and tapped on the shoulder of a man in a gray business suit.

 The two of them returned and I handed the model SLS to the man. He examined it carefully.

 “This is it!” he half whispered never taking his eyes off the model, “This is the SLS, they’ve never given us a model of it.”

 He asked if he could borrow it for a while? He told me that he had several network TV interviews to do and he’s like to use it.

 “Sure!” I replied gleefully.

 With that he and his group of minions left as he carefully carried the model.

 "Who was that?” I asked the guy from LockMart.

 “That,” he replied with a wide smile, “is John Karas, the Vice President and General Manager of Human Space Flight for Lockheed Martin.”

 Holy shit.

 It turned out that STS-135 took place so close to the Obama rift that no one had yet produced a model of the SLS… but me. So, Mr. Karas arrived at KSC nearly empty handed, but really wanting to talk about the SLS.

 “Anyone who makes Mr. Karas smile like that,” the fellow from LockMart said happily, “gets some swag.”

I ended up with a ball cap, some pens and a few trinkets to take home and give to my kids. We stood there for a long time and talked model rockets, and I explained that I’d started my company to keep busy while I raised my two daughters. Although I’m a successful author, it was tough to write books when you cannot sit and focus quietly for hours on end. Because as a parent, you never get to do that. 

After about 40 minutes Mr. Karas and his minions returned.

“Thank you so much,” he said as he extended his arms to return to model to me, “I love this rocket.”

 “Well,” I replied, now knowing who I was actually speaking to, “you can have it.”

 “Really?” he exclaimed.

 “Yeah, it’s one of two identical prototypes. I have another one just like it on my work bench at home.”

 Pulling back the model he admired it again, took a deep breath, turned to his minions and ordered, “Let’s get this man something!”

 Suggestions came popping up- a pass to a test firing- an invitation to a dinner event, and on and on.

 “Let’s give him an Orion model!” someone shouted.

 “That’s it!” Mr. Karas ordered as he pointed to the minions, “Get him one of those Orion models!”

 Less than a minute lapsed before one of the minions showed up carrying a square cardboard box. Packed in custom foam rubber was one of the newest, museum quality, 2011 Orion models. I took it back to the press room and got the attention of the other hardcores.

 “Guess what I just got from John Karas?” I said as I held the box above my head.

 “You dog! You got a model!” several of them guessed before I opened the box and showed it off.

 Indeed. It flew home with me, never out of my reach, destine for display in my office.

 Today, the flight version of the Orion is very different from my model. But I see it in the same light of the early Apollo era photos where NASA people as shown posed with a Lunar Module or Command Service Module that always looks nothing like the final product. I pondered those models when I was a kid. Now those models are worth thousands of dollars. Yet to me, this one not only connects me with my childhood ponderings, but it reminds me of the day I made John Karas very happy.

ARTEMIS SRBs: THE POWER AND HISTORY

 

By Wes Oleszewski; Aero-News Network Spaceflight Analyst

Propelling the Artemis II launch vehicle will be two types of rockets. At its core the Space Launch System (SLS) booster has four liquid fuel RS-25 engines. But most prominent are the two Solid Rocket Boosters (SRB) strapped to each side of the core. When the Artemis II launches toward the Moon, it will do so by way of these incredibly powerful and fairly historic SRBs.

Developed for the Space Shuttle program the Artemis SRBs are longer. Each stands 177 feet tall and weighs in at 1.6 million pounds. Burning a polybutadiene acrylonitrile (PBAN) propellant, the combination of the two SRBs produces 7.2 million pounds of thrust at liftoff. To put that in historic perspective, the Apollo 17 Saturn V that sent the last crew to the Moon produced 7.7 million pounds of thrust at liftoff. So, when combined with the Artemis II core stage of the SLS booster lifts off with 8.8 million pounds of thrust. The total burn time is just two minutes and six seconds before the SRBs are jettisoned into the Atlantic Ocean. Unlike the Space Shuttle, the Artemis SRBs are not recovered for reuse.

Additionally, the unusually cold weather in Florida this week has drawn a number of myopic and uninformed questions as well as countless social media posts citing the Challenger disaster and comparing that to now. Challenger was destroyed by one factor. Engineers were ordered by managers to “Take off their engineer’s hat and put on their management hats” in order to push for the launch to take place outside of the test data temperature envelope. That caused the burn through of the SRB segment joints which triggered the disaster. Artemis is NOT Challenger. The current SRBs have been specifically re-engineered to assure such will not happen again.

A foundational element of the SLS booster is that it was developed to leverage Space Shuttle technology. In its earliest concepts the Shuttle did not have SRBs but instead was composed of two huge airplane-like vehicles. By the end of 1971 there was only one aircraft in the system which was boosted by two SRBs and three liquid propellant orbiter engines fueled by an external tank. This configuration was first shown in model form to President Richard Nixon on January 3, 1972. Nixon was fascinated by the model and two days later released a statement where he gave it, not only his approval, but also the name “Space Shuttle.”

Large Solid Rocket Motors (SRM) were nothing new in 1972. Because on June 8, 1965, the largest SRMs in the world boosted the first Titan IIIC from Cape Canaveral Launch Complex 40 for the U.S. Air Force. Those 120-inch diameter, five segment boosters combined to produce 2.647 million pounds of thrust making the Titan IIIC the most powerful launch vehicle in the world at that time. Thus, in the early 1970s NASA elected to use two SEBs consisting of four segment each to boost the Shuttle. Those SRBs were 147 inches in diameter and the combination of the two produced 5.6 million pounds of thrust at liftoff. Over 135 launches only one of those boosters failed and that was due to it being fired at temperatures outside of its published performance limitation. Most of the other SRBs were recovered and reused.

Thus, Artemis SRBs are assembled from former Shuttle SRBs. One adaptation is the SLS will fly on five segment SRBs rather than the Shuttle’s four segment boosters. As a result of all this, Artemis II SRBs are composed of an assortment of sections with an amazing Space Shuttle history. As an example, a combined 84 different Shuttle missions total will fly on Artemis II. The left SRB has portions with a history of being used in nine ground test firings and 47 Shuttle missions. As an example, that SRB’s forward skirt has flow 14 times. Meanwhile, the right-hand booster has also been used on nine ground test firings, and its forward skirt has also been flown on 14 missions. But that SRB has an accumulated record of an amazing 64 missions overall. Additionally, the same SRB’s upper most segment, cylinder 86, is the oldest of the segments on Artemis II and dates all the way back to STS-5 when it boosted the orbiter Columbia on November 11, 1982.

In the Artemis program the SRBs are no longer recovered for re-use. This is because the cost of recovering, refurbishing, transporting and reloading a single SRBs has, over the history of their use, added up to a good bit more than simply making a new SRB. The same rule applies to the RS-25 engines on the SLS core stage.

Yet, when you see Artemis II launch, you now know the both the power and the history.
