Operation Paperclip

Sixty-five years ago today — September 20, 1945 — “Operation Paperclip” brought Dr. Wernher von Braun and six other German scientists to the United States.

The first seven technicians arrived in the United States at New Castle Army Air Base, just south of Wilmington, Delaware, on September 20, 1945. They were then flown to Boston and taken by boat to the Army Intelligence Service post at Fort Strong in Boston Harbor. Later, with the exception of von Braun, the men were transferred to Aberdeen Proving Ground in Maryland to sort out the Peenemünde documents. These would be the documents that would enable the scientists to continue their rocketry experiments.

Finally, von Braun and his remaining Peenemünde staff were transferred to their new home at Fort Bliss, Texas, a large Army installation just north of El Paso. Whilst there they trained military, industrial and university personnel in the intricacies of rockets and guided missiles and helped to refurbish, assemble and launch a number of V-2s that had been shipped from Germany to the White Sands Proving Grounds in New Mexico.

(From this article on Operation Paperclip.)

This Wikipedia article also mentions September 1945, though it locates Fort Strong in New York instead of Boston Harbor; in contrast, this article states that the first scientists did not come to the U.S. until November 18th.

But come to the U.S. they did, and they helped us win the space race. As Dan Berlinrut, one of my USAF colleagues, put it many years ago, we beat the Soviets to the Moon “because our Germans were better than their Germans.”

However, their Germans were very good — and the Russian rocket scientists were no slouches themselves. We see whose launch systems are being abandoned and whose continue to operate, don’t we?

We ran the space race as a sprint, but it’s really a marathon. Will we decide to run a different race, or will we continue to lag?

[BREAK, BREAK]

I missed a space anniversary yesterday: 50 years ago yesterday, on September 19, 1960, NASA launched an Argo D-8 rocket from Vandenberg AFB carrying the “Nuclear Emulsion Recovery Vehicle.” As stated on this history page, the suborbital launch “reached an altitude of 1,260 miles before landing 1,300 miles downrange where it was picked up by U.S. Navy ships. It was the first manmade object to travel to such an altitude in space and be recovered upon its return to Earth.” (It was also NASA’s first launch from Vandy.)

Satellite Triple Play, Plus One

Twenty-five years ago today — August 27, 1985 — astronauts Joe H. Engle, Richard O. Covey, James D. Van Hoften, William F. Fisher and John M. Lounge lifted off from the Kennedy Space Center aboard Space Shuttle Discovery.

Mission STS-51I lasted a week, during which the crew deployed three communications satellites: American Satellite Company 1 (ASC-1), Australian Communications Satellite 1 (AUSSAT-1), and Synchronous Communications Satellite IV-4 (SYNCOM-IV-4), also known as LEASAT-4 because most of its communications capacity was to be leased out to the military.

The crew also retrieved SYNCOM-IV-3 (LEASAT-3), which had been launched the previous April by STS-5lD but had failed to activate. As described on this Boeing page,

After attaching special electronics assemblies to LEASAT 3 during two days of space walks, astronauts manually launched the satellite again. The electronics allowed ground controllers to turn on the satellite and, at the end of October, fire its perigee rocket and send LEASAT 3 into orbit.

While LEASAT-3’s repair was a success, LEASAT-4 developed its own problems. The satellite reached its intended orbit, but its ultra high frequency (UHF) downlink failed during testing and it was declared a total loss.

First Successful CORONA Mission

Fifty years ago today — August 18, 1960 — Discoverer-14 launched from Vandenberg AFB. It was known to the public by that name, but to insiders in what would become the National Reconnaissance Office it was known as CORONA Mission 9009.

Discoverer-14 was the first CORONA mission in which the film canisters were successfully recovered from orbit.

The National Space Science Data Center describes the film recovery process:

Over Alaska on the 17th pass around the earth, the Agena ejected Discoverer 14 from its nose and retrorockets attached to the reentry vehicle fired to slow it for the return from orbit. After Discoverer 14 reentered the atmosphere, it released a parachute and floated earthward. The descending parachute was sighted 360 miles southeast of Honolulu, Hawaii, by the crew of a US Air Force C-119 recovery aircraft from the 6593rd Test Squardon based at Hickam AFB, Hawaii. On the C-119’s third pass over the parachute, the recovery gear trailing behind the aircraft successfully snagged the parachute canopy. A winch operator aboard the C-119 then reeled in the Discoverer after its 27-hour, 450,000 mile journey through space. This was the first successful recovery of film from an orbiting satellite and the first aerial recovery of an object returning from Earth orbit.

The NSSDC also notes that “38 Discoverer satellites were launched by February 1962,” although the CORONA project itself continued until 1972. CORONA was declassified in 1995.

Spy Satellite Proof-of-Concept Launch, 50 Years Ago

A half-century ago today — August 10, 1960 — Discoverer-13 launched from Vandenberg AFB on a Thor-Agena rocket.

Discoverer-13, and indeed the entire Discoverer series of spacecraft, was part of the highly classified CORONA program managed by the National Reconnaissance Office. Discoverer-13 did not take any images itself, however, as it was used to prove that all the systems would work. Discoverer-14 took the program’s first images a few days later.

The Discoverer-13 capsule splashed down in the Pacific Ocean and became the first man-made object recovered from space. The first segment of this YouTube newsreel video shows President Eisenhower being presented with a U.S. flag that flew inside the capsule.

First Titan Launches on Solid Rocket Motors: Titan-IIIC

Forty-five years ago today — June 18, 1965 — the first Titan-IIIC (“three C”) launched from Cape Canaveral on a test flight.


(A 1978 Titan-IIIC launch. USAF image from Wikimedia Commons.)

The IIIC was the first Titan variant to use strap-on solid rocket motors for additional lift capacity. The Air Force flew a large number of SRM-augmented Titans through the years. This Aerospace Corporation article has a little of the Titan vehicle history.

The SRMs were built up in segments, with each full-size segment being ten feet in diameter and ten feet tall. The Titan-IIIC and IIID models used two five-segment SRMs each; the later Titan-34D used a pair of five-and-a-half-segment SRMs, while the Titan-IVA used two seven-segment SRMs. The last Titan model, the Titan-IVB, used the SRMU — solid rocket motor upgrade — which consisted of fewer, but larger, motor segments.

And why do I care about the SRM and SRMU details? Because I had the privilege of working on parts of the Titan program — primarily dealing with the solid rockets — during my assignments at Edwards (Titan-34D and Titan-IVA test firings, Titan-34D launches) and Vandenberg (Titan-IVA and -IVB launch processing facilities).

Another Space Shuttle Precursor Flies

Forty years ago today — June 2, 1970 — NASA test pilot William H. “Bill” Dana flew the Northrop M2-F3 lifting body on its first flight.


(M2-F3 lifting body on the dry lakebed at Edwards AFB. NASA image.)

The M2-F3 was one of a series of lifting bodies flown by NASA and the USAF to test spacecraft reentry. On this flight, it was dropped from its B-52 mothership and Dana glided it to an unpowered landing on the dry lake bed at Edwards AFB, much the way Shuttle pilots glide their vehicle back to Earth.

The M2-F3 was rebuilt from the crashed M2-F2, with a center stabilizer added to reduce the pilot-induced oscillations that had caused the M2-F2 landing mishap. Powered flights of the rocket-equipped M2-F3 eventually took it up to Mach 1.6 and over 70,000 feet of altitude.

On a personal note, I wish I had known more of this history back in the late 1980s, so I could have asked Mr. Dana some pertinent questions when I met him at Edwards.

Bell X-1, Chuck Yeager, and Salad

This is more “air and space” than “space” history, and it’s as much of a curiosity as anything, but 60 years ago today — May 12, 1950 — Chuck Yeager flew the first Bell X-1 rocket plane (serial number 46-062, or X-1-1) on its final flight.


(Bell X-1 in flight. USAF photo from NASA image collection.)

The aircraft, the first to be flown faster than the speed of sound, was retired and sent to the Smithsonian Institution, where it is on display at the National Air and Space Museum. If you’ve never been, you should go. (And the new Udvar-Hazy annex to the museum is very nice, too.)

Semi-related personal recollection to explain the title: I remember seeing General Yeager in the Officers Club at Edwards AFB when we were stationed there. I didn’t talk to him — what’s a brand-new second lieutenant non-pilot going to say to someone like that, especially standing next to him at the salad bar? But it seemed pretty cool at the time … and pretty okay even now.

First Molniya Satellite — Highly Elliptical Orbit for High Latitude Communications

Forty-five years ago today — April 23, 1965 — the Soviet Union launched Molniya-1 on a Soyuz rocket from Baikonur.

The satellite was placed in a very particular orbit: highly elliptical, with perigee (the lowest altitude) very close to the Earth’s southern hemisphere and apogee (the highest altitude) far above the northern hemisphere. By carefully selecting the angle of inclination (how “tilted” the orbital plane is from the equatorial plane), they produced a situation in which the satellite’s apparent motion over the northern hemisphere was very small, providing extended communications coverage in the polar regions where geosynchronous satellites could not.

The orbit soon became known as a Molniya orbit, after the Molniya satellites that were first inserted there. “Molniya,” itself, means “lightning.”

Here’s a wonderful YouTube video showing how the Molniya orbit works:

And, congratulations to the Air Force’s X-37B team for their successful launch last night. (Head to the Space Warfare Forum if you want to discuss it.) Well done!

NATO SATCOM, Four Decades Past

Forty years ago today — March 20, 1970 — the NATO-1 communications satellite was launched from Cape Canaveral on a Delta launch vehicle. Placed in geosynchronous orbit over the Atlantic Ocean, the satellite provided secure, reliable communications support to North Atlantic Treaty Organization leaders.

X-Series Flight Testing Continues at Eddie's Airplane Patch

Forty years ago today — March 19, 1970 — USAF test pilot Major Jerauld R. Gentry made the first powered flight in the X-24A lifting body.

(X-24A with rocket engine ignited after being dropped from the B-52 carrier aircraft. NASA image.)

The same B-52 used in the X-15 program (and later in the Pegasus program*) carried the X-24A to about 40,000 ft (13,860 m) altitude, where it was dropped and its rocket engine took the rest of the way through its flight profile. It then glided to a landing on the dry lakebed at Edwards AFB.

Over the life of the program, the X-24A made 28 powered flights, reaching a maximum speed of 1,036 mph (1,667 km/hr) and a maximum altitude of 71,407 ft (21,765 m). According to the project description on this page, NASA later used the X-24A’s shape as the basic profile for the X-38 Crew Return Vehicle demonstrator.

*Full disclosure: When I was stationed at Edwards (1986-90), I was on the Flight Readiness Review committee for the first Pegasus launch from that same B-52.
