Top News Item: (as of June, 2005)

June 23rd, 2005:  THANK GOODNESS LOUIS FRIEDMAN, PLANETARY SOCIETY DIRECTOR, who just lost his puppy (launched from a Russian sub; it may have been swapped for a Russian spy satellite!) WAS NOT IN CHARGE OF CASSINI!  Dr. Friedman -- at this web site -- was an arrogant supporter of Cassini.  But now we know:  He can't even fly his own bird!  So THANK GOODNESS Dr. Friedman wasn't in charge of Cassini! Cassini was a bad idea and so is New Horizons.

April 25th, 2005:  NASA/ PENTAGON, HOW COULD YOU?

As if New Horizons and Prometheus weren't bad enough, now we learn that YES, Global Network was "infiltrated"!  But by WHO?  Gagnon was one of the main TARGETS!  Here's what Bruce Gagnon, subject of much undeserved speculation at this very web site, has ACTUALLY been going through:


As the Global Network (GN) prepares for its 13th annual space organizing conference in New York City, on April 29-30 [2005], a call came into our office today [4/21/2005] from the American Civil Liberties Union (ACLU).

The ACLU office in Brevard County, Florida (where NASA and the Kennedy Space Center are located) called to inform the Global Network that an ACLU investigation of the Brevard County Sheriff's department has revealed 600-700 pages of internal files documenting extensive infiltration and surveillance of the Global Network and other anti-war activities in the county during recent years.  The files contained descriptions of Global Network members as being "anti-American."

The ACLU investigation, which began last January, also revealed that NASA was gathering information on European demonstrations against the launching of weapons and nuclear power in space during recent years.  In addition, the Air Force Office of Special Investigations (OSI), based in Tampa, Florida, had infiltrated the Global Network as late as October of 2002 during the organization's annual Keep Space for Peace Week.

According to the ACLU the investigations centered on Global Network Coordinator Bruce Gagnon and Global Network members Mary Beth Sullivan and Maria Telesca.  In addition to infiltration of the organization, the ACLU noted that the investigations included background checks, driving histories, address histories, as well as other information gathering activities.

The ACLU has requested permission to pursue legal action on behalf of Bruce, Mary Beth, and Maria.  The ACLU intends to attempt to retrieve all surveillance files gathered on Global Network members and to pursue a possible lawsuit.

A LETTER TO "MRS. CASSINI" (Addenda) (Posted August 18th, 2004)

SEPTEMBER 20th, 2003: Good Riddance, Galileo!


(PLEASE CLICK HERE FOR A "FLASH MX" ANIMATED INTRO TO THE PROBLEM OF NUKES IN SPACE -- requires FLASH MX & IE6 or Netscape 7 -- comprises one download of about 400K)

No RTGs AND no RHUs in space!

NASA is careful to tell the public it's not using Radioactive power sources (generally known as RTGs) for any planned missions to Mars. (Example: Scott Hubbard, NASA Mars Director, April 10th, 2001, CSPAN: "All the missions up through 2005 are solar-powered...").

But they ARE using Radioactive Heater Units (RHUs). Each one provides a modest amount of heat but uses 2.7 GRAMS of plutonium (mostly Pu 238).

Each one has hardly any containment system at all and contains millions of potentially lethal doses of plutonium!


At this website is the science and philosphy behind why Cassini should have been stopped.

Welcome to perhaps the world's most controversial web site ever!

More NASA lies.

A correspondence between opposing forces:
An ongoing series of emails between Mike Pelletier and Russell Hoffman. This email from Hoffman discusses NASA documentation about Cassini's RTG's.

FALSE, TRUE... and TRUER. An answer to a NASA/JPL document.
"NASA hides the real facts and the real math inside complex verbal descriptions, tables of exponential numbers, and inappropriate calculations. This is NASA's biggest problem: Bad science is being used to bolster the few weak real arguments NASA has to justify pursuing the nuclear option. In fact, the nuclear option is a dead end." By Russell D. Hoffman.

Space Probe Explodes, Plutonium Missing
The November, 1996 Russian Mars space probe which crashed back to Earth instead. By Karl Grossman. Published at the Covert Action Quarterly (CAQ) web site.

An answer to NASA PR person Mary Beth Murrill's email to Frederica Russell.
In which Murrill lamely refutes the allegation that the RTGs are designed to incinerate on Earth flyby re-entry. By Russell D. Hoffman.

Draft Supplemental Environmental Impact Statement for the Cassini Mission
NASA sent this document to me, via Certified Mail, Return Receipt Requested. So I read it, and you know what? I can't argue with the science! Yep, can't argue with it at all. Not a bit. Why not? Because there's no science to argue with! There are only conclusions drawn from selected data, while other relevant data is ignored. NASA's draft statement was open for review until May 27th, 1997! By Russell D. Hoffman.

Cassini: An In-Depth Look

"How does 72.3 pounds compare with what was lost in Chernobyl and every other accident? It's an absurd question! It's cumulative. If you jump out of an airplane, just because you have fallen 30,000 feet is no reason not to pull the rip cord for the last 500 feet of descent!" Written by Russell D. Hoffman. Note: This article is also available in German, thanks to the translation efforts of Marcus Hammerschmitt.

Although Cassini was launched as planned in October, 1997, there are still be many good reasons to try to alter the trajectory and avoid the dangerous Earth flyby scheduled for August, 1999. Furthermore, Cassini is really just the proverbial the tip of the nuclear iceberg that is being planned for space! We will keep up with events throughout the coming years, as they occur, for better or for worse. We will remain, at the very least, a stone called the truth in NASA's shoe. They will always know that the truth has been presented, and well before launch. And so far, that they have ignored it.

There are several of them available on the Internet. This simple and straight-forward one is from the NY Greens. They were delivered to President Clinton before launch.
