Re: China's Space Program, News & Views

NK-33 was a developed version of NK-15, intended for use on upgraded version N-1. It differs from the NK-15 in having simplified hydraulic system, simplifed interface with rocket body, slighly improved combustion chamber and better turbo pumps.

The relationship between NK-33 and NK-15 is probably closer then those between J-2 and J-2X

Thanks for your answer Chuck. So the Soviet never did test the newer NK-33 on their N-1 rockets before it was shut down?

Very cool stuff.

And US NASA Mars Rover Opportunity, after over TEN YEARS on Mars. What a marvel! Here she is on top of Solander Point, and the second is the path she took to get there.

Posters from the Chinese Space Program Thread:
Earlier today I moved a number of posts that were off topic in the Chinese Space Program Thread, and which I had indicated needed to get back on topic there, to this thread here in the Member's Club Room. I moved three different groups of posts here that were dealing with different aspects of the Russian Space program.

Regrettably, while doing so, one of those groups of posts was inadvertently lost. Chuch731 brought this to my attention earlier today and I have tried to recover them but to no avail. I apologize and will do my utmost to be more careful in the future.

If one of your posts that was off topic there is no longer on that thread and is not here on this thread, it was most probably included in the group I lost. There were probably six or so posts in that group. Again, I apologize for the error.

Re: China's Space Program, News & Views

What am I verifying?

I know that the NK-33 was built. I know that they were decent engines for their time. I know some of them were left over.

However, I do not believe that over a hundred of them were secretly stashed away against orders and maintained for years in any type of good condition.

What apparently happened is that a few dozen were left in storage for decades and not all that well maintained.

NASA did not buy them. Of those that were left, ultimately Aerojet, a private company, got a good deal on something like three dozen of them to configure for cargo missions to the International Space Station. I believe they have used them for three missions to date, the last being this month...and they have contracts with NASA for something like total of 16 missions.

Aerojet had to do quite a bit of modifying to make them work for the mission and it was not without issue. They removed a lot of harnessing, had to add a lot of modern electornics, new propellants were used, they were modified for gimbal steering, and then qualifed for all of that...but ultimately they did work, and that is a good attribute to the original designers of those engines for sure.

Anyhow, this is off topic to China's Space Program. What China is doing is quite impressive in its own right and I expect we are gpoing to see a lot more of it. So let's get back on topic to the Chinese space program. If you would like to have a discussion about the Russian Program, start a thread in the Members Club Room aboiut the Russian Space Program, it's current status and history.
In a way they did. the NK33 is used as in the Orbital Sciences Antares launch system which is part of Commercial cargo.
And Areojet derivative versions are supposed to power the Space Launch System.
Of course I am A critic of the SLS, so I question if it will ever happen.

I thought I would touch on the amazing Mars rovers the US has deployed to Mars over the years. Three different types of rovers for three different missions over 17 years now:


PIA15279_3rovers-stand_D2011_1215_D521_br.jpg


In the front is the flight spare for the first Mars rover, Sojourner, which landed on Mars in 1997 which was a part of the Mars Pathfinder Project. It was 2 feet long. On the left is test rover of the Mars Exploration Rover Project, a working model of the Spirit and Opportunity rovers , which landed on Mars in 2004. They are each 5.2 feet long. Then, on the right, is a Mars Science Laboratory model of the Curiosity rover which landed on Mars in August 2012. It is 10 feet long (that's one big rover).

The Opportunity is still roving after 10 years. The Curiosity is going very strong.

Here is a picture of Mount Sharp by Curiosity in September 2012:

Here is a picture of the Rocknest area taken by Curiosity in November of 2012. For all the world it looks like it could be in Nevada or Arizona:

Toxic Russian Rocket Fuel Target of Kazakh Anger
24 January 2014
By Matthew Bodner The Moscow Times

A nationalist political party in Kazakhstan has called on the government to ban future launches of Russian Proton-M carrier rockets from the Baikonur Cosmodrome over concerns that they spew a particularly toxic form of rocket fuel into the Kazakh steppe.

The Proton-M is the workhorse of Russia's unmanned and commercial space programs. It uses a type of fuel called heptyl, which is a highly corrosive combination of hydrazine and nitrogen tetroxide, topped off with kerosene.

The Nationwide Social-Democratic Party of Kazakhstan, or NSDP, released a statement on Wednesday calling for Proton-M launches to be banned from Baikonur over the dangerous residues the rockets leave on Kazakh territory.

"The time has come when the government of the Republic of Kazakhstan should, at last, listen to common sense and the citizens and radically revise the policy on foreign rocket launches from the territory of Kazakhstan!" the statement said, Interfax-Kazakhstan reported.

"It is impossible not to pay attention to the pollution of the environment from [spent stages falling off the rocket], the vast amount of toxic heptyl rocket fuel and its derivatives," it said.

Kazakhs have become increasingly concerned with the hazardous effects of Proton launches following a series of embarrassing launch failures in recent years. NSDP said that "serious and fair questions about Russian space activities on the territory of our country" have arisen in the wake of the failures.

The statement went on to say that "in spite of local protests and the country's active civic population as a whole," the Kazakh government has virtually banned discussion on this "vitally important topic" and that members of the "anti-heptyl movement" are subject to constant persecution by the authorities, despite what they call their sincere concerns for public health and the ecological well-being of the Kazakh countryside.

The Proton-M has been beset by a series of embarrassing launch failures in recent years. Traditionally considered to be the most reliable rocket ever designed, the Proton-M is not the only tried-and-true Russian launch vehicle to experience uncharacteristic failures in recent years, prompting many observers to question the overall health of the Russian space industry.

The most notorious incident involving heptyl occurred after a launch failure last summer. Shortly after clearing the launch tower, a Proton-M carrying three GLONASS satellites valued at $200 million suddenly and dramatically veered off course, crashing directly into the ground. Because the failure occurred a mere 17 seconds after liftoff, the vehicle hit the earth with a nearly full tank of its toxic fuel.

Talgat Musabayed, head of the Kazakh Space Agency, estimated that the rocket carried nearly 600 tons of fuel at impact.

As the stress of its short flight began to tear the rocket apart before hitting the ground, some of the heptyl was released into the air unburnt. Fumes were spotted drifting above the nearby city of Baikonur, home to 70,000 people, prompting city officials to post fliers around town warning residents to stay indoors and refrain from using air conditioners until the clouds dispersed. Baikonur is known for being extremely hot.

Also at play are issues of sovereignty arising from the intergovernmental agreements governing Russia's use of the Baikonur Cosmodrome, which the NSDP views as an affront to "the concept of sovereignty of Kazakhstan!"
Chances of it happening.... 0% the Russians spend so much on the Belkanor and employ so many that it would be political suicide for anyone in power to do it.
Dream Chaser Space Plane Will Fly in 2016
January 23, 2014 at 4:58:00 PM by Joshua A. Krisch



Dream Chaser, the private space plane built to shuttle astronauts and cargo to the International Space Station, is ready to leave the Earth.

In a news conference this afternoon, the Sierra Nevada Corporation (SNC) announced that Dream Chaser will blast into orbit in November 2016 atop an Atlas V rocket. Dream Chaser's first orbital flight will be unmanned and will test the space plane's autonomous landing system. SNC expects to launch its first manned orbital mission about one year later.

"SNC is thrilled to be the first company to confirm a launch date for our country's return to orbital human spaceflight, and the restart of human spaceflight operations from Florida's space coast," said Mark Sirangelo, Corporate Vice President of SNC's Space Systems, at the conference.

Dream Chaser, which hopes to take the place of the space shuttle in ferrying humans to orbit for NASA, bears a striking resemblance to its predecessor. Like the shuttle, Sierra Nevada's spacecraft is a lifting body, meaning it has wings to provide lift (as opposed to a capsule, like SpaceX's Dragon.) Inspired by NASA's SL-20 crew rescue vehicle, Dream Chaser was built with astronauts in mind. "The space shuttle was designed to carry a huge amount of cargo," said Steve Lindsey, SNC's Dream Chaser program manager. "[Dream Chaser] is primarily designed as a people carrier."

Dream Chaser will fly into orbit on an Atlas V rocket, a launch system closely related to the one that carried John Glenn into space in 1962. After a one-day mission that will test orbital operations, the space plane will attempt an autonomous, horizontal landing. Although Dream Catcher suffered a landing gear malfunction during its first free flight landing last year, SNC officials are confident that they will be ready for orbit by 2016.

"We are planning to launch, we are building the vehicle to be launched, and we have made the commitment to launch," Sirangelo said.

Very good news on the first flight of the Dream Chaser being announced.

I am hoping it wins the competition and becomes the go forward vehicle. If I was 15 or 20 years younger I might make an all out effort to work on that program...or the Ford carriers, or the Burke IIIs, or the F/A-XX...err, well, you get the picture. LOL!.
