SPACEPORT MICHIGAN
When Rockets Flew From the Great Lakes State: 1962-1971
GLEN E. SWANSON
1. INTRODUCTION
Everyone loves a good story. So it was 5 years ago when I first got wind of a whopper of a tale based on rumour that an active rocket range once existed in the state of Michigan. Being a space flight historian and a native "Michigander," if rockets once flew from the Great Lakes State, I had to know more.
During my off-and-on again research, I did confirm that an active rocket site once existed and that rockets were launched over a period of six years. I was able to talk with those who were involved with the project. Their accounts tell not of a routine scientific endeavour but of an adventure which includes humour, drama, suspense - all the classic elements of a story waiting to be told - the story of Spaceport Michigan.
The idea of establishing a mid-continent rocket launching site was first proposed by the University of Michigan's Institute of Science and Technology in 1962. On 1 November at a meeting of the National Academy of Science's Space Science Board's Committee on High Altitude Rocket and Balloon Research, Mr. L.M. Jones and Dr. Harold E Allen described a technical study being carried out by the Institute outlining the possible advantages of locating a site in Northern Michigan. They pointed out that an immediate and vital use of such a facility would be to add a station to the then existing Meteorological Rocket Network (MRN).
The Meteorological Rocket network was established in October 1959 at the request of the US Army. The idea behind establishing a co-ordinated launch system was twofold: need and opportunity.
At this time, the development of small rocket systems had given scientists a unique opportunity to study the general structure of the atmosphere between 20 and 70 miles. It was impossible to explore these altitudes with balloons and prohibitively expensive with sounding rocket experiments.
The first series of MRN firings occurred from two stations in October 1959. Successful results were obtained from these first launches and a second series of firings followed in January 1960 from three stations. The number of flights steadily increased each year as more sites were brought into use in the Network. Continued expansion of the MRN on a national and international basis had been supported by various scientific groups from around the world, including the US National Academy of Sciences.
In a recommendation drawn up during a 1962 Committee on Space Research (COSPAR) meeting in Washington, D.C. the valuable results that emerged from the previous sporadic and localised launchings were recognised. As a result, COSPAR strongly urged "an increase in the number of stations from the present 20-25 sites to at least 50, so that reasonably complete maps can be drawn of the wind temperature patterns in the Northern Hemisphere."
Because a large gap existed in data coverage over North America, the MRN sought to establish a station somewhere near the interior of the continent. All the present launch sites were located in a semi-circle reaching from Fort Greely in Alaska, down the Pacific coast, up along the Atlantic coast and ending at Fort Churchill, Canada. Upon release of the University of Michigan's initial report in early 1962 [1], it was suggested that the south shore of Lake Superior, in northern Michigan, would be a good location for a rocket range. There were many places between the Upper Peninsula city of Sault St. Marie and the Wisconsin border that have very low population densities where such a range could be safely located. The lake itself could serve as an impact area.
It was also pointed out that the Midwest United States has many research groups that would welcome such a nearby facility. Furthermore, the location would be farther north and closer to the geomagnetic poles than any other US launching site except Fort Greely near Fairbanks in Alaska. In addition, co-ordinated experiments with rockets, many of which were underway for the period of the International Year of the Quiet Sun (IQSY, 1964-1965), could take advantage of the new site to significantly enhance the scientific value of the US contribution to this international study.
Following the University of Michigan`s initial report, the National Science Foundation, the Space Science Board of the National Academy of Sciences, the US Weather Bureau and other interested agencies requested that they carry out a technical feasibility survey beginning in late 1962. "The MRN was looking for a station in the centre of the continent because they, had things only around the rim and they wanted something in the interior," said Dr. Harold E. Allen during an interview at his home in Ann Arbor. Now retired, Allen worked for the University of Michigan as Range Director and was with the Michigan rocket range project from the beginning. "The only place that they figured could be good would be somewhere in the Great Lakes area. Here you would have areas that might be clear for the impact of the spent rockets. The MRN approached me and asked if I would be interested in doing a survey for this. I said that I would be delighted."
Their survey concluded that the tip of the Keweenaw Peninsula would be the most advantageous location and that small and medium range sounding rockets could be safely launched from this point on a year-round basis, although there were a few problem areas that would have to be overcome.
One of the biggest concerns involved the rocket impact area. The end of the Keweenaw Peninsula is located almost in the middle of Lake Superior, one of the most heavily navigated waterways in the world. There were 10,000 cargo ship movements recorded through the locks at Sault Ste. Marie during the 1961 navigation season, which usually lasts from May through December. an average of 38 ships per day. It would do no one any good to have a spent rocket come crashing through some ship's hull, adding a totally new chapter to Great Lakes folklore. Studies showed, however, that the impact areas for small rockets would well-clear commercial shipping channels: and since there is little or no pleasure boating or fishing on this portion of the lake, these areas would usually be clear at all times.
"The lake has a lot of traffic on it just as most of the Great Lakes do," recalled Allen. "But there is a sizeable area above and below the shipping lanes for impact of small and medium size rockets. "The impact area must not only be clear of ships but also clear of aircraft as well before a rocket could be fired. There is considerable military and commercial air traffic in the area. especially during the summer months. The airspace over the entire region is under continuous surveillance by the 665th Radar Squadron of the Air Defense Command at Calumet Air Force Station, about 22 miles west of the launch site. Commercial air traffic is under control of the Minneapolis Air Route Traffic Control Center. As a result, during an actual launch both military and commercial pilots would have to be informed and under certain circumstances. may be required to detour to avoid the impact area.
In spite of such assurances, it was recommended that once a site had been established, that most of the rocket launches would occur during the winter months when both shipping and air traffic was minimal. This. as we shall soon discover, had both its advantages and disadvantages.
2. IN THE BEGINNING: 1964
During the summer of 1964, construction began on the Keweenaw Range, which was activated on a temporary basis using a minimum of facilities and personnel. The State of Michigan provided a grant of $52,850 for this purpose, and the Goodman Lumber Division of Calumet & Hecla. Inc., donated 203 acres of land to the University of Michigan. Access easements were granted by Calumet & Hecla and by the Copper Range Company. Site preparation, access roads and the transportation of equipment to the site were arranged by the Keweenaw County Board of Supervisors and the City Highway Commission.
There was a Coast Guard Station manned 8 months out of the year on nearby Manitou Island that could give additional aerial surveillance and communications. A private telephone line owned by them ran past the site to Manitou Island. They allowed the scientists at the site to tap into this line, giving them communications to any place in the world.
Some sheet metal buildings were obtained from the fishery's department for use at the site. They had been used to house generators for wires strung across rivers to kill lamprey eels. Said Allen, "They had the lamprey eels pretty much under control so they figured that they did not need these buildings any more and gave them to us."
Once built, five rockets and five AN/DMQ-6 meteorological payloads were furnished by the US Weather Bureau. Two Arcasonde 11 payloads were supplied by the Pacific Missile Range of the US Navy. Both types of payloads were manufactured by the Atlantic Research Corporation and were no longer in use at any established range. The reason for their use in this case was that no tracking radar was available for range determination. The DMQ-6 and Arcasonde II were intended to provide continuous wave ranging information using an auxiliary ground based transmitter and a remitter in the payload.
An Areas rocket launcher was loaned by the US Army Research and Development Activity at White Sands Missile Range, New Mexico. A van-mounted Rawinsone GMD-1A set, a power generator and a 75-foot telescoping tower assigned by the US Army to the Willow Run Laboratory of the University of Michigan were loaned to the Range. The tower was used as an antenna mount and for wind profile measurements required for determining launcher settings.
Project personnel included three regular employees of the University of Michigan (John Wescott, Harold Allen and Orest Chapilsky), two from Michigan Technological University at Houghton, Michigan (Peter Gels and Robert Gaabo) and two from White Sands Missile Range (W.N. Jacobs and Billy Wilson). This represented the bare minimum of crew and equipment sufficient for small rocket operations.
On Wednesday morning at 7:07 am, 6 August 1964, Michigan took its first steps toward the space age. A slender Arcas rocket, about six feet long and weighing 76 pounds, was launched with a payload of meteorological instruments to an altitude of 41 miles before plunging into Lake Superior 20 miles east of the launch site five minutes later. A metallic parachute, which served as a radar target, lowered the payload after ejection.
The Arcas measured temperature, air pressure, density and wind velocity, which were radioed back to the ground until impact. No attempts were made to recover the payloads - except once. "We had a fairly good north wind during one of our Arcas launches," recalled Allen. "One of the parachutes drifted ashore just west of Marquette. Someone was driving along the road and saw this parachute float past heading into the woods. He thought 'My God. somebody had to bail out of an airplane'. So he called the police. They got out there and had a big gang search for the parachute. They finally found it stuck in a tree. They cut the whole tree down and brought the thing back to us. We could have used it again if we wanted to."
Following the completion of the five Arcas launchings in September, the GMD and telescoping tower were returned to Ann Arbor. The launcher was shipped back to White Sands for use on another project and the Keweenaw Range closed for the season.
3. PROJECT WEBROC: 1965-1966
The Keweenaw Range was reactivated the following year to conduct research with the Office of Naval Research for a project called WEBROC. A small defence company called Space Defense, based in Detroit, was the prime contractor for this project.
The WEBROC project was led by a commander in the US Navy named Malcolm Ross, who attained fame for being one of the first men to enter the fringes of space before the manned space programme. Before Project Mercury, development of an effective spacesuit had begun, but scientists needed to check their initial designs under actual space conditions. Ross and another man, Charles Moore, were placed in a pressurised vessel attached to a balloon and successfully ascended to an altitude of over 120.000 feet [2].
The goal of the WEBROC Project was to set up a network of permanently anchored buoys in remote ocean areas to obtain weather information. The buoys would house rocket launchers for firing small rockets with various payloads. Fired remotely, these rockets would be tracked and their data transmitted to satellites. The buoys would contain weather vanes, anemometers, water temperature sensors and other instruments designed to record the surface conditions. Using these buoys, ground stations would be able to obtain valuable weather data comparing surface conditions to that at various altitudes in these remote regions.
The rockets selected for use were 2.75-inch folding-fin aircraft rockets. Called "Mighty Mouse," they had four fins that folded up so that they could easily fit inside a tube. These tubes were then put under the wings of aircraft and found extensive use in World II.
To protect them from the elements, the developers of the WEBROC project planned to use these rockets in an enclosed launcher housed in a pot on the buoy. As a result, the developers needed to know if they could be fired from a closed-breech launcher.
"In 1965- 1966 we ran a bunch of tests at Keweenaw for the WEBROC project," said Allen. "In 1965 we made a bunch of ground tests with closed-breech launchers to see whether it would effect the trajectory of the rocket or whether it was possible to shoot the thing out without any damage to the rocket."
In 1966, additional testing was done from the Range using a buoy made out of six gasoline drums with a small platform on it. On this platform another gasoline drum rested which contained four rocket launchers. The idea behind this test was to see how well rockets could be fired from a buoy.
Allen recalls, "They brought the buoy out but by the time they set it up it was early fall and snow was coming down. We put the thing together over at Lake LaBelle, which is on the South side of Keweenaw, and the Coast Guard towed it out to the point. We tried to fire the rockets from the buoy but something happened to the firing line. They would not fire."
They towed the buoy into Copper Harbor, made repairs and had the Coast Guard tow them back out for another try. "I'll be damned but the same thing happened again. The Rockets would not fire," recalled Allen. Again, they hauled the buoy back to shore to make repairs. By this time, the weather was getting bad and the waves were getting pretty high. The Coast Guard was busy hauling up their own buoys so the team called upon a local fisherman for help. "Wally Jamson took us out for one last time in his fishing boat," Allen continued, "Again, the rockets would not fire. So we decided, what the heck, we know the problem is in the connection to the boat so why don't we just simply take this thing down to the point and rather than fire it from the buoy, just fire it from the ground. We did just that, and of course everything worked fine."
4. A LEAN YEAR: 1967
During 1967, the Range saw relatively little use. A company in Ann Arbor had an interest in micro-meteorology and wanted some tests performed at the Range. They developed some very sensitive weather instruments and wanted to test them in flight.
"Again, we decided to use the same 2.75-inch folding-fin aircraft rockets but put a payload on the front end with titanium tetrachloride in it," said Allen. As soon as the rocket is launched, the several g's of acceleration forced the titanium tetrachloride out through a small orifice at the rear of the payload bay, creating a spray that rapidly evaporates and forms a cloud. The horizontal winds at different altitudes would blow this cloud around which could then be photographed with fast-acting surveying cameras. The resulting images would allow scientists to determine the wind directions and velocities of the upper atmosphere.
5. PROJECT NOMAD: 1968-1969
Using results obtained from the Range during the WEBROC Project, Space Defense developed a bigger and more sophisticated buoy for the Office of Naval Research. Called NOMAD, the buoy housed 50-60 launchers containing 2.75-inch folding-fin aircraft rockets along with an extensive array of measuring instruments and radio equipment.
Weighing nearly 10 tons and looking like a small ship, the Coast Guard Carrier Woodrush carried NOMAD off the Keweenaw point where it was anchored in Lake Superior to be tested.
"We fired a number of rockets from the buoy itself by radio control," recalls Allen. Everything went well - most of the time.
"Of course the rocket launcher was aimed straight up," explained Allen, "but as the buoy rocket around in the water it would sometime change the rockets trajectory. Once a rocket landed about 50 feet off the point. We always got under the van whenever a rocket went off so in case it did come down near us it wouldn't knock anybody out."
The road to the launch site, where they were controlling the launches from the buoy, was supposed to be a private drive. Gates were installed with warning signs clearly posted. However, this did not discourage the curious. "Every once and a while somebody would come out there and decide it was a good place for a picnic," recalled Allen. "So we would have to chase them off. They of course did not like that, but we did manage to successfully complete the project.”
6. IN THE END THE APACHES CAME: 1970-1971
It is perhaps fitting that if the ambitious plans for the Keweenaw Range had to end, that they would end with an ambitious launch.
"In the fall of 1970," remembers Allen, “I got a call from Will Nelson, head of the department. He said that 'Goddard (NASA-Goddard Space Flight Center) wants to launch two Nike-Apaches from the Keweenaw Range. Do you think you can do it?' I said that it will take some doing but we'll give it a try."
NASA wanted to secure data on stratosphere warmings, an annual winter phenomenon in which warmings of the upper atmosphere spread southward from the Arctic. This warming effect pre-stages the change in seasons, but scientists were uncertain as to what caused the initial effect. Through these launches, NASA officials hoped to obtain data that would provide a reliable explanation as well as help in trouble-shooting various radio communications systems.
Each Nike-Apache would travel more than 100 miles above the ground and radio back its data. The first rocket to be launched, designated 14.167Gl, would carry a payload designed to measure the effects of magnetic storms caused by solar flares. The second rocket, 14.373GI, would carry a payload of five basic experiments designed to measure electron density, positive ion composition and distribution, energetic electron precipitation, solar X-rays and Lyman Alpha flux.
So began the Keweenaw Range's most ambitious project. Because Nike-Apache rockets were considerably larger and more powerful than anything launched before from the Range, a considerable amount of work had to be done to prepare the site.
The first thing that had to be done was to survey the area. "We started in October," recalls Allen. "They wanted an area big enough for their vans plus an enclosed heated building for rocket assembly and a rocket launcher." NASA would furnish the rockets, launcher and various support personnel. "We had to furnish everything else."
Land had to be cleared and roads had to be rebuilt to accommodate the heavy equipment vans. Concrete was poured for the launch pad and buildings and five one-hundred-foot-tall poles had to be secured for the antennas. "We selected five good straight white pine trees, cut them down and saved them for the antennas said Allen, "and that was the easy part. You see there is very little top soil in that region so we had to blast holes in the rocks using dynamite in order to put these things in." Building contracts were sent and arrangements had to be made to assure clear air space and that no ships would be in the area during the time of launch. "We were busy people," said Allen, "in the face of an oncoming north country winter."
The firings of the two Nike-Apaches were supposed to take place in the middle of December, but some of the equipment from Goddard did not show until later that month. The instrumentation van, the heaviest and most delicate piece of equipment to arrive was so heavy that they had to use a bull-dozer to help it up the hilly roads that led to the site. "The community was very helpful during that time. Every time we fell into a hole and had troubles, there was somebody in the area that could help us out."
By the end of December, they were ready for launch but the payload van did not arrive until the first of January. By then, all hell had broken loose.
"Right after they got here we had the damnedest blizzard you ever saw," said Allen. "We got all set and read to go and it snowed for 19 straight days without stopping. Ninety-four inches of snow fell that month, a new record for the region. It closed everything," said Allen. "We had to get the county plough to come out and plough the road out to the launch site. The county road commissioner himself came out with the plough to make sure that they did a good job for us. He charged us only $10 for plowing 10 miles of highway."”
"This storm was way beyond any limits that they allowed us to fire rockets," said Allen. "We were on the wire with Wallops Island and with Goddard Space Flight Center all the time. We had orders not to fire the rocket under those conditions."
Because these two rockets were more powerful and had a greater range than anything launched before from the site, there was always the concern as to what degree the winds would effect their trajectories. "The one disadvantage at the Keweenaw site was that we could not shoot toward Marquette," remembers Dempsey B. Bruton Jr., Field Operations Manager at Wallops Island. Bruton worked at the Keweenaw during the time of the Nike- Apache flights. "You also had the Canadian border running down through the centre of Lake Superior. To avoid any international incident, we had to keep the impact inside the lake but not in Canadian territory." At that time, this looked to be quite a challenge.
After waiting nearly the entire month for weather conditions to improve, Goddard called and said, "if you don't fire it by the 29th, pack the rockets up and send them back to Wallops," recalled Allen. On 29 January conditions were marginal but they proved to be good enough for a launch. "We got one of the Nikes off," recalled Allen," and they got the data back and everything was first rate."
The next day, conditions worsened and it looked as though they would not be able to launch the second rocket. "The weather almost killed us," said Allen. "I was again on the phone with Goddard and they told me that come the next day, if we don't get it off the rocket goes back to Wallops." "Everybody was pulling to get this rocket off," remembers Burton. "And the wind was howling and the snow was flying but it was steady."
To fire a rocket you select a place where the thing is going to hit - your target point. Under a no-wind condition you can aim for that target with a rather small circle of error. But if there is a wind, you normally have problems. If there is a lateral wind, it will have a tendency to cause the rocket to drift, increasing your margin of error. If the wind blows on the rocket during the time it is firing (thrusting), it will blow across the fins used for stabilising the rocket (if it is a lateral wind) causing the rocket to tilt. Because these effects on the rocket can occur at different times during flight, it is important to know the effect of the wind at every altitude in order to try to compensate.
Those that calculate the effect of the winds that determine the target and launcher settings are called "wind weighters" because they calculate the effects or "weight" of the wind on the rocket. "We wind weighed the thing," explained Bruton. "We set off high altitude balloons and took anemometer readings to try and get the data as good as we could." The wind-weighters made calculations all that day and found that the conditions stayed steady.
"The winds were blowing like mad," said Bruton, "but they stayed constant all the way up. So these guys made their launchers settings and they were wild, they were big, but they were always nearly the same.' Allen had fired hundreds of rockets from Wallops Island, Virginia and had confidence in the crew at Keweenaw. "Goddard was concerned, and rightly so, that the rocket might land smack in the middle of the city of Marquette" said Allen. "So I asked to speak with the Range Director from Wallops." Allen talked with the Director reassuring him that they could launch the rocket on target. It began to get late in the day and darkness began to fall. "Finally, he said 'OK let's do it."
"So we put the phone down and went away and fired the damn rocket," said Allen. On 31 January, the second Nike- Apache Launched beautifully and landed within ten miles of the impact point. When they phoned Goddard to explain what they had done, they were furious. "They flew off the handle," recalls Allen. "They were going to shoot everybody." After getting word back from data recovery that all the data was great and that everything was fine, they cooled down. They said, "I guess it was all right," recalls Allen, "but don't ever do it again."
They never did do it again. The flights of 1971 were the last for the Keweenaw Range." After the two successful Apache flights," recalled Allen, " we had all of this junk scattered around under six feet of snow that had to be pulled up and taken back. It was well into February before we got everything shipped out of Copper Harbor. That was the end. We never got any more contracts."”
In explaining why the Keweenaw Range closed down, Allen explained that it had more to do with a lack of funding and interest rather than for any reasons resulting from their last two launches. "It got to the point where they were not willing to spend any more money," said Allen. Dr. Fred L. Bartman agrees, recalling that, "work at the site petered out after the two Nike- Apache flights as competition in this field got greater and it became more difficult to get funding." Bartman served as director of the University of Michigan`s High-Altitude Research Laboratory during that time.
Lack of support from NASA and other agencies also helped contribute to its premature demise. Bartman recalled that, "NASA only had a nominal interest and was never really convinced that this was a good site. Although they supported the effort up there for a while. they eventually became no longer interested." Even if support for continuation of the site existed today, it would be difficult to operate safely. "At that time the entire east end of the Keweenaw Peninsula was uninhabited," recalls Allen. "Today it would be difficult to operate a site safely because much of the shoreline has been developed. Shipping and air traffic through the region have also steadily increased over the years." Even though the site closed down, those that worked on the project fondly recall more ambitious plans for the Range if it had survived.
There were plans on the board to increase the capabilities of the site to accommodate progressively larger and larger rockets and more frequent launches," remembers Allen. "We sought to make it a permanent facility with a larger yearly launch rate of medium size, two-stage, general-purpose sounding rockets of the type we launched last." These long range plans even included the possibility of launching satellites into orbit.
"NASA had a number of surplus Redstone rockets at the end of the Mercury programme and they wondered what to do with them,"” recalls Allen. "We put in a proposal to fire some of them from Keweenaw for extreme high-altitude research or for surveillance purposes over the Soviet Union. We could have fired [payloads lofted by] them into polar orbits or northward over the Soviet Union and land them down in India, China, Japan or even the Philippines. The trajectories went right over practically uninhabited country in Canada. We would have had to get international permission but it would have been possible."
Once closed down, the land was given to Michigan Technological University (note: the property is still owned by the U of M). Eventually, the property was abandoned and the buildings destroyed.
Seldom known, the story of Spaceport Michigan is only a small chapter, seasonal at best, in sounding rocket history. For a while, rockets once flew from the Great Lakes State as a group of dedicated scientists tried to push for a more permanent role in the space age.
