Comments Off on A European Symphonie and the Health of Our Planet

Thirty-five years ago today — December 18, 1974 — the first European-built communications satellite was launched aboard a Thor-Delta rocket from Cape Canaveral. Symphonie-1 was a cooperative French-German spacecraft, as detailed on this Wikipedia page. (Note that the page lists the launch as December 19th because it’s based on UTC — what used to be known as Greenwich Mean Time — but it was still the 18th on the East Coast of the US.)

And 10 years ago today, an Atlas-2AS rocket launched Terra, a joint US-Japanese-Canadian weather satellite, from Vandenberg AFB.

Terra was “the first of a series of large satellites meant to monitor the health of our planet” by monitoring cloud formation, radiation balances, and aerosols in the atmosphere. As the NASA web site puts it, “Terra’s primary mission is to answer the question: How is the Earth changing and what are the consequences of change for life on Earth?”

This page shows some interesting comparative images taken by Terra.

Comments Off on Two Launches: One Local, One to Venus and Halley's Comet

Forty-five years ago today — December 15, 1964 — the San Marco-1 satellite launched from Wallops Island, VA, on a Scout rocket. This was the first in a series of Italian atmospheric science spacecraft, and the only one to be launched from the U.S.

Succeeding missions were launched starting in 1967 from the San Marco platform, a converted oil platform anchored off the coast of Kenya. I find that fascinating, as the San Marco platform was a precursor to the Sea Launch operations I observed over 30 years later.

And 25 years ago today, in 1984, the Soviet Union launched its Vega-1 mission atop a Proton-K rocket from the Baikonur Cosmodrome. (I wonder if it was processed in the same building in which I later saw the Nimiq-2 satellite get mated to a Proton launch vehicle.) Vega-1 — also known as Venera-Halley 1 — was a very successful mission that deposited a lander as well as a set of balloon-borne experiments on Venus, and then continued to a 1986 flyby of Halley’s comet.

Rocket Sleds and Murphy's Law — and a Couple of Rocket Launches, Too

Comments Off on Rocket Sleds and Murphy's Law — and a Couple of Rocket Launches, Too

Fifty-five years ago today — December 10, 1954 — U.S. Air Force Colonel John P. Stapp rode a rocket sled at Holloman AFB, New Mexico, to over 600 mph. Stapp set a record for the greatest recorded g-forces endured by man when the sled decelerated. From his obituary in the New York Times,

Dr. Stapp was known as the ”fastest man on earth” for his 1954 ride, though the speed has since been surpassed and was never accepted by auto racing officials as an official land speed record. The speed was impressive, at any rate. Dr. Stapp accelerated in 5 seconds from a standstill to 632 miles an hour. The sled then decelerated to a dead stop in 1.4 seconds, subjecting Dr. Stapp to pressures 40 times the pull of gravity.

Stapp’s early rocket sled tests were done at Edwards AFB, and I remember seeing the old tracks and trenches out on South Base. It was during those early tests that Stapp fell victim to what became known as Murphy’s Law:

Dr. Stapp . . . suffered an injury in the experiment that inspired Murphy’s Law after a somewhat less rapid sled ride in 1949.

An assistant, Capt. Edward A. Murphy Jr., had designed a harness to strap in the rider. The harness held 16 sensors to measure the acceleration, or G-force, on different body parts. There were exactly two ways each sensor could be installed. Captain Murphy did each one the wrong way.

The result was that when Dr. Stapp staggered off the rocket sled with bloodshot eyes and bleeding sores, all the sensors registered zero. He had been strained in vain.

A distraught Captain Murphy proclaimed the original version of the famous maxim: ”If there are two or more ways to do something and one of those results in a catastrophe, then someone will do it that way.”

If rocket sleds don’t quite qualify as “space history” for you, there were two December 10th rocket launches that fit the bill. First, 35 years ago today, a Titan III-E rocket launched the Helios-1 spacecraft from Cape Canaveral. Helios-1 was a joint effort by the U.S. and West Germany to measure the solar wind and examine the surface of the sun. And on December 10, 1999, the European Space Agency launched an Ariane 5 rocket from Kourou, French Guiana, carrying their X-ray Multimirror Mission (XMM) telescope. XMM-Newton was the ESA’s equivalent of NASA’s Chandra space observatory.

Comments Off on Space History, a Half Century Ago: Little Joe-2

Fifty years ago today — December 4, 1959 — the “Little Joe-2” rocket launched from Wallops Flight Facility, Virginia, with a very special passenger: the rhesus monkey “Sam.”

Sam reached an altitude of over 50 miles and traveled nearly 200 miles downrange before landing in the Atlantic Ocean. The US Navy recovered Sam and the boilerplate Mercury capsule; here’s a link to a post-flight photo of Sam.

Comments Off on Space History Today: Prep Flight for Apollo-Soyuz

Thirty-five years ago today — December 2, 1974 — cosmonauts Anatoliy V. Filipchenko and Nikolai N. Rukavishnikov launched from Baikonur aboard Soyuz-16. Their flight was a pathfinder for the upcoming Apollo-Soyuz mission in 1975, and was the only manned test flight leading up to the joint US-USSR mission.

Fascinating details about the Soyuz-16 mission, including some of the geopolitical considerations, can be found on this page.

Mariner-4 arrived at Mars on July 14, 1965, where it conducted the first successful flyby of the planet and sent back the first pictures of the Martian surface.

Maybe Mariner would be a good name for the first ship to take people to Mars. Sure wish I could go….

Comments Off on Four Launches: Scout, Thor-Delta, Atlas-Centaur, Titan

This day in space history, November 21, was a busy day for launches. They were launched at five-year intervals, but still …

Today in 1964 — 45 years ago — NASA launched its first dual payload when it sent up Explorer-24 and Explorer-25 on a Scout rocket from Vandenberg Air Force Base.

Forty years ago today, in 1969, the United Kingdom sent up its first communications satellite. Skynet-1 launched on a Thor-Delta rocket from Cape Canaveral.

On November 21, 1974 — 35 years ago — an Atlas-Centaur rocket launched from Cape Canaveral carrying the Intelsat IV F-8 communications satellite.

And 30 years ago today, in 1979, a Titan-IIIC rocket out of Cape Canaveral sent up two Defense Satellite Communication System satellites, DSCS II-13 and DSCS II-14.

We shouldn’t forget, of course, that 40 years ago today the U.S. also had astronauts returning from the moon. Mission Commander Charles Conrad, Jr., Command Module pilot Richard F. Gordon, and Lunar Module pilot Alan L. Bean made their transearth injection at 3:49 p.m. EST on November 21st, 1969.

An Astronomer's Astronomer, and a New Space Telescope

Comments Off on An Astronomer's Astronomer, and a New Space Telescope

One hundred twenty years ago today in space history — November 20, 1889 — astronomer Edwin P. Hubble was born in Marshfield, Missouri.


(Edwin Hubble, next to the Hooker Telescope at Mount Wilson Observatory. NASA image.)

Hubble earned his B.S. in mathematics and astronomy at the University of Chicago in 1910, and studied law at Oxford University as one of the first Rhodes Scholars. He served briefly in World War I, and returned to earn his doctorate at the University of Chicago. He spent his entire professional career at the Mount Wilson Observatory in Los Angeles. Among his discoveries, Hubble:

  • Found that Andromeda is a separate galaxy from our Milky Way
  • Went on to discover dozens of new galaxies outside our own
  • Classified galaxy types, as shown here
  • Calculated the rate of expansion of the universe

NASA, of course, honored Hubble by naming their most famous space telescope after him.

And speaking of space telescopes, 5 years ago today, in 2004, NASA launched the Swift Telescope — also known as the Gamma Ray Burst Explorer, or Explorer-84 — on a Delta-II rocket from Cape Canaveral. The spacecraft, named after the bird, carried three instruments to detect and locate gamma ray bursts.

I think Edwin Hubble would be thrilled to see the new discoveries that have been made, by the telescope that bears his name as well as other, specialized instruments.

And I wonder what’s next….

Speaking of Chinese Space Ambitions…

Ten years ago today in space history — November 19, 1999 — the People’s Republic* of China launched an unmanned Shenzhou capsule on a Long March 2F rocket from the Jiquan launch center.

The capsule was an enlarged version of the Russian Soyuz design, developed for a human space flight program originally known as “Project 921.” According to SPACEWARN Bulletin 553, the vehicle “carried a mannequin for test purposes” and “parachuted down in Inner Mongolia after orbiting for 21 hours.”

The renamed Shenzhou program would successfully place a Chinese astronaut (a “taikonaut”) in orbit not quite four years later, in October 2003.

I wonder how much the Chinese owe to Hughes and Loral for the success of this flight and the Shenzhou program. Did the Chinese engineers and technicians rework anything on this Long March rocket after the accident investigations into the Optus, Apstar, and Intelsat launch failures? (I refer readers to chapter five and chapter six of the Cox Commission Report for background.) We’ll never know. They would have gotten to this point eventually, no doubt.

Flash forward** to yesterday in space history: NASA announced that they intend to explore cooperative space ventures with the Chinese (not quite a year after the last Administration turned the idea down). The message now? Steal our technical know-how, and continue to violate your own people’s human rights, but we’ll still cooperate with you in the greatest adventure of Mankind.

For more on Chinese space ambitions, see this thread in the Space Warfare Forum.

*Young people, or people who don’t understand what the fuss is all about, may not recognize the irony of a Communist country calling itself a “republic,” and especially a “people’s republic.” See “doublespeak,” as in “Orwellian.”

**Not to be confused with Robert J. Sawyer’s excellent novel, Flash Forward, which I understand is also a pretty good television show.

Searching the Cosmos for Background Radiation

Comments Off on Searching the Cosmos for Background Radiation

Twenty Years Ago — November 18, 1989 — the Cosmic Background Explorer, or COBE, was launched atop a Delta rocket from Vandenberg Air Force Base. Here’s the 20th anniversary press release.


(Artist’s depiction of the COBE spacecraft. NASA image.)

And here’s a link to another nice artist’s conception of the spacecraft.

COBE was designed to measure the microwave background radiation left from the early universe. COBE carried three instruments:

  • Diffuse Infrared Background Experiment (DIRBE), to search for infrared background radiation
  • Differential Microwave Radiometer (DMR), to map the cosmic radiation
  • Far Infrared Absolute Spectrophotometer (FIRAS), to compare the background radiation to a known standard

The astrophysics behind it are beyond me, but I like the pretty pictures.
