Bye Bye Twitter?

I first joined Twitter in March of 2006. At the time part of my job at Rocketdyne Propulsion and Power, a division of The Boeing Company, was to examine platforms described as examples of what was then referred to as Web 2.0, as well as new applications being referred to as “social media.” I was doing this as a member of the Knowledge Management team for the division, and as the Knowledge…

"The Saturn I S-IV stage (second stage) for the SA-7 mission being prepared for shipment to Cape Canaveral, Florida. The S-IV stage had six RL-10 engines, which used liquid hydrogen and liquid oxygen as its propellants, arranged in a circle. Each RL-10 engine produced a thrust of 15,000 pounds for a total combined thrust of 90,000 pounds. The SA-7 mission was launched on September 18, 1964 from Cape Canaveral, Florida, and its S-IV stage made the second orbital flight."

Date: January 8, 1964

I can't find a source from a real quick look but the hoops and striations are because the engine bell is made from a zillion little pipes brazed together, so it can be liquid-cooled with the liquid oxygen that's then burned.

Actualizaciones para Todos los motores agregados a la etapa central del cohete lunar Artemis II de la NASA

El cohete más poderoso del mundo El 25 de septiembre de 2023, ingenieros y técnicos de la NASA, Aerojet Rocketdyne y Boeing completaron la instalación de los cuatro motores RS-25 en el escenario central del cohete del Sistema de Lanzamiento Espacial (SLS) de la NASA. Esta es una etapa importante en el desarrollo del SLS, que es el cohete más poderoso del mundo. Los motores RS-25 son motores de…

The SLS (Space Launch System) Core Stage by Numbers

Technicians with NASA and SLS core stage lead contractor Boeing, along with RS-25 engines lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, are nearing a major milestone for the Artemis II mission. The SLS (Space Launch System) rocket’s core stage for Artemis II is fully assembled and will soon be shipped via barge from NASA’s Michoud Assembly Facility in New Orleans to the agency’s Kennedy Space Center in Florida. Once there, it will be prepped for stacking and launch activities.

Get to know the core stage – by the numbers.

Standing 212 feet tall and measuring 27.6 feet in diameter, the SLS core stage is the largest rocket stage NASA has ever built. Due to its size, the hardware must be shipped aboard NASA’s Pegasus barge.

900 miles

Once loaded, the barge – which was updated to accommodate the giant core stage -- will travel 900 miles to Florida across inland and ocean waterways. Once at Kennedy, teams with our Exploration Ground Systems team will complete checkouts for the core stage prior to stacking preparations.

18 Miles + 500 Sensors

As impressive as the core stage is on the outside, it’s also incredible on the inside. The “brains” of the rocket consist of three flight computers and special avionics systems that tell the rocket what to do. This is linked to 18 miles of cabling and more than 500 sensors and systems to help feed fuel and steer the four RS-25 engines.

8.8 million

Speaking of engines… Our SLS Moon rocket generates approximately 8.8 million pounds of thrust at launch. Two million pounds come from the four powerful RS-25 engines at the base of the core stage, while each of the two solid rocket boosters produces a maximum thrust of 3.6 million pounds. Together, the engines and boosters will help launch a crew of four Artemis astronauts inside NASA’s Orion spacecraft beyond Earth orbit to venture around the Moon.

733,000 Gallons

Achieving the powerful thrust required at launch calls for a large amount of fuel - 733,000 gallons, to be precise. The stage has two huge propellant tanks that hold the super-cooled liquid hydrogen and liquid oxygen that make the rocket “go.” A new liquid hydrogen storage sphere has recently been built at Kennedy, which can store 1.25 million gallons of liquid hydrogen.

Four

The number four doesn’t just apply to the RS-25 engines. It’s also the number of astronauts who will fly inside our Orion spacecraft atop our SLS rocket for the first crewed Artemis mission. When NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover along with CSA astronaut Jeremy Hansen launch, they will be the first astronauts returning to the Moon in more than 50 years.

Defense contractor L3Harris to procure Aerojet Rocketdyne for $4.7B

L3Harris Technologies Inc. announced an agreement to acquire Aerojet Rocketdyne Holdings Inc. in a $4.7 billion transaction that would cement L3Harris' position as one of the Pentagon's six primary defense contractors.

Aerojet is a major manufacturer of missile engines, including the Javelin used by Ukraine. Its product also helps power NASA rockets and US military hypersonic systems designed to counter China's military expansion.

Aerojet was relisted for sale after federal regulators filed suit in January 2022 to block Lockheed Martin Corporation's planned $4.4 billion acquisition of the company on antitrust grounds, sparking a bitter internal board battle.

According to individuals involved in the negotiations, L3Harris' all-cash offer of $58 per share trumped competing bids from General Electric Co. and Textron Inc. A transaction is anticipated to face intense regulatory scrutiny at a time when Aerojet is also experiencing production difficulties. Continue reading...

Linear Aerospike SR-71 Experiment (LASRE) by NASA on The Commons Via Flickr: The NASA SR-71A successfully completed its first cold flow flight as part of the NASA/Rocketdyne/Lockheed Martin Linear Aerospike SR-71 Experiment (LASRE) at NASA's Dryden Flight Research Center (now NASA Armstrong), Edwards, California on March 4, 1998. During a cold flow flight, gaseous helium and liquid nitrogen were cycled through the linear aerospike engine to check the engine's plumbing system for leaks and to check the engine operating characteristics. Cold-flow tests had to be accomplished successfully before firing the rocket engine experiment in flight. The SR-71 flew for one hour and fifty-seven minutes, reaching a maximum speed of Mach 1.58 on this flight.

Deming and Rocketdyne

Sometime in late January of 1987, almost one year to the day after the Space Shuttle Orbiter Challenger was destroyed as it ascended to orbit, I was assigned by the temp agency I was using at the time to begin work on the Space Shuttle Main Engine team at Rockwell International’s Rocketdyne Division in Woodland Hills, CA. Prior to that fateful date I had, with one exception, never worked at a…

Every fandom has its bad side and worse side. I am not ok with trolls going around saying Vince sacrificed Skylar for fame either

the real people to blame for this is boeing and rocketdyne. They were the ones releasing radiation and dumping chemicals near the neighborhood where Vince and sharise lived at getting people sick and giving them cancer and unfortunately Skylar was a victim who did not survive

Also let it be known that a lot of these manufacture and chemical companies are still dumping toxic waste close to residents today!

Hello, anon! Thank you for your wise words and bringing awareness to the situation. It is very unfortunate how this whole thing occurred.

For anybody who wants to know more I will provide a short excerpt from an article I found. I will also paste the link for those who want to read the article in its entirety.

The lead singer for Mötley Crüe has sued Boeing North American Inc., claiming that his daughter's death by cancer in 1995 was caused by radioactive material dumped in the soil and ground water near his former home near the Santa Susana Field Laboratory.

Vince Neil and his ex-wife, Sharise, bought a home in Chatsworth in 1991, a few miles east of Boeing's Rocketdyne Division. Boeing acquired the property in 1996 when it bought Rockwell International's aerospace and defense businesses.

The suit claims that Boeing, Rockwell, and Rocketdyne knowingly dumped hazardous materials, such as plutonium and uranium, near the Neils' Summit Ridge Circle residence southeast of Simi Valley.

Their 4-year-old daughter, Skylar, was diagnosed with a rare form of cancer in April 1995 and died four months later. The suit claims that her death came "as a direct result of the activities conducted by defendants."

It’s disgusting how these companies are still getting away with this!
