Early Atmospheric Research
TIME magazine reported in 1959: "Van Allen's 'Rockoons' could not be fired in Iowa for fear that the spent rockets would strike an Iowan or his house." So Van Allen convinced the U.S. Coast Guard to let him fire his rockoons from the icebreaker Eastwind that was bound for Greenland. "The first balloon rose properly to 70,000 ft., but the rocket hanging under it did not fire. The second Rockoon behaved in the same maddening way. On the theory that extreme cold at high altitude might have stopped the clockwork supposed to ignite the rockets, Van Allen heated cans of orange juice, snuggled them into the third Rockoon's gondola, and wrapped the whole business in insulation. The rocket fired."
The Office of Naval Research (USA ONR) used the Loki in some of its Rockoon launches, lofting the Loki to high altitudes on a helium balloon before firing, for upper atmosphere research. The first Rockoon launch of the Loki I occurred on Jul 1 1955 from shipboard off the coast of Greenland.
During Jul-Oct 1955 instrumented Loki I and Deacon rockets were successfully balloon launched (Rockoons) from shipboard off the coast of Greenland in cosmic-ray studies by The University of Iowa research group. Army Ordnance supplied JPL-developed Loki rockets and ONR sponsored the project.
The first attempt of the Deacon Rockoon on Aug 21 1952 06:25 GMT from the Arctic Ocean 80.1 N x 68.5 W was a failure. However, success came on Aug 9 1953 in the Atlantic Ocean, Launch Site 11 Launch Point 10 74.38 N x 71.93 W, at 05:54 GMT. Quickly followed by another success on Aug 30 1953 20:46 GMT at Atlantic Ocean Launch Site 11 Launch Point 13 53.13 N, 54.75 W.

Famous quotes containing the words early, atmospheric and/or research:
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
“Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.”
—Ralph Waldo Emerson (1803–1882)
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
