Hey Guys,

 

What functionality does the Orion provide over Dragon/Starliner?

 

I know dragon is half the weight, I just dont know what the Orion does that is worth the extra weight.

 

 

 

 

If they used dragon and the ESA service module, would the falcon heavy have enough thrust, with the extra 10% with the block 5.

A full service module (propulsion, consumables stores, more batteries etc.) Not that SpaceX couldn't build one on a pallet to fit inside the Trunk and add lines to the Dragon Claw umbilical. That and some high density polyethylene radiation shielding. Yes, HDPE is a rather good shield. Extra points if you add about 5% elemental boron to shield neutrons.

 

Essentially enough to take the mission life with a crew from a few days to Orion's 21.1 days

Mission life with a crew aboard and a bit more radiation shielding. See above.

FH could launch a Crew Dragon and crew on a lunar free return trajectory, a loop-around, and not have mission life issues. Maybe add some HDPE for shielding, but it's not that heavy.  This would have been the Grey Moon mission which was replaced by #blueMoon using Starship.

 

Add the aforementioned service module pallet to the Trunk and who needs Orion - or SLS? (but that's politically incorrect in Florida, Alabama, Colorado or Chicago [Boeing's home base])

All of the above, which SpaceX won't need to bother with at all since Starship is able to carry 100 people + a modest 100 metric tonnes of cargo to Mars ... so figure another 50 metric tonnes of mass saved for the moon (since they won't have to carry all of the extra consumables for the long Martian mission).

 

More than doable for a Lunar mission on Starship. That's why Crew Dragon won't need to do it. It's a mission slated for Starship; in fact, already paid for. One of the first ones will be doing a once-around.

 

Orion is not needed in any context. At the time it was ordered, yes. Now, no.

Crew/Cargo Dragon may end up being used for the Gateway station under CLPS etc., But Starship would be insane for that mission.

 

First, it's several times larger than the Gateway, making the optics look bad for NASA. 

 

Second, who would be docked to who? Again, way too large for the mission.

Are they still ignoring Starship?  lol

Yes, for now. Once Starship stats high altitude tests that gets a LOT harder.

NASA has finally acknowledged Starship!  lol

 

Potential mission managers and line engineers see the handwriting on the wall long before upper management suits, and with the pics & hops at Boca Chica Twitter has cranked up the volume to 11.

Wasnt the issue that Orion was too heavy for FH/DIVH to send direct, it would need to dock with a second stage in orbit and the Orion doesnt have the ability to do the docking?

 

Do we have any more information about how they would get around the issue, are they bringing the docking functionality forward?

Dock in orbit with an SLS ICPS upper stage, separately launched.

 

AKA: Distributed Launch

NASA Admin. Bridenstine said flat out the only vehicle-side docking system the US has with a flight history is SpaceX's version of the International Docking Adapter, so ICPS would need to use "IDA-X" to dock with Orion.  "IDA-X" is also simpler and cheaper than Boeing's unit.

 

Boeing developed IDA, it is used on ISS and Orion, and SpaceX's version has docked with it (Crew Dragon DM-1).

Blithering idiots.

 

Use 1 or the other, NEVER mix them!

I so wish, growing up, we were taught the metric system in the US. I have "learned" it but still am not used to it like I would be if I had grown up using it. Why anyone would use both in a car is beyond me but in space?

I was taught the metric system in the 1960's, in a farm community (one-room schoolhouse for grades 1-5).

 

The issue has been implementation at the govt, industrial and supplier levels. This results in generations of legacy products & regulatory pages specifying Imperial. Not to mention road signs etc.

NASA does not deny the over $2 billion cost of a single SLS launch

"NASA is working to bring down the cost of a single SLS launch."

For the first time, a government cost estimate of building and flying a single Space Launch System rocket in a given year has been released. This estimate of "over $2 billion" came in the form of a letter from the White House to the Senate Appropriations Committee first reported by Ars this week.
>
Dont forget development costs
>
What the White House cost estimate did not include, however, was development costs. Since 2011, Congress has appropriated approximately $2 billion per year for the "development" of the SLS rocket (this does not include hundreds of millions of dollars spent annually on ground systems "development" for the rocket at Kennedy Space Center). 
>
Adding all of this up, the true cost of a Space Launch System mission with Orion on top in the 2020s, including the rocket's development but excluding ground systems and Orion development costs, appears to be in the ballpark of $5 billion per flight.

Let's hope the astronauts are served more than just pretzels after takeoff.

Cost of Orion

 

NASA IG: Twenty. Nine. Point. Five. Billion. Dollars. 😱

 

NASA: $11.3 billion 😲

Quote

WASHINGTON — NASA’s inspector general criticized the agency for its accounting of Orion program costs in a new report, arguing it has “hindered the overall transparency” of the program amid growing costs and schedule slips.


In a July 16 report, NASA’s Office of Inspector General (OIG) raised several issues with costs of the Orion program, including the agency’s decision to exclude many costs from a formal cost estimate for the program as well as “overly generous” award fees paid to the prime contractor, Lockheed Martin, over the life of the program.

Through January of 2020, the latest financial data was available, NASA spent $16.7 billion on Orion, dating back to the Constellation program. NASA estimates spending $12.8 billion on Orion through 2030, primarily on production of future spacecraft.

While that suggests a total of Orion through 2030 of $29.5 billion, NASA’s formal estimate for life cycle costs for the program is $11.3 billion,

I wonder how many SpaceX's that much money would get you...

Seems like it's several steps backwards to me now, the whole SLS concept.

 

Throw away most of the rocket at launch ... it's so ... crude. Brute force is all well and good, but ... blech. It smacks of yesterday's technology. :no: 

 

I dislike it immensely.

They have been tasked with a semi-impossible goal. Go back to the moon and stay there before 2024. No time to do proper research and development of new ideas and technologies. Luckily you (we) have SpaceX.

    • A different thing with Russia. When you say is it better, depends on things. It is better that we don't have the E.U making rules and laws that have nothing to do with them. Is the trading part better? No, that is really mucked up, but then we knew that was going to happen and we would have make agreements, like we do with other parts of the world. Freedom of movement is certainly better, but could be improved, we still need more control over our borders. do you live in the U.K?
    • So what am I quoting from them? I never listened to what Farage or his cronies said. I wanted the U.K to leave the E.u years before the referendum and it had nothing to do with Farage and his cronies. So what country do you live in? Did we work much better together? We were always at logger heads with the E.U because we disagreed with them so much. Maggie was always on at them. I would have thought the E.U was glad to get rid of us as we stopped the integration or made it a two tier. Now without us they can integrate more. I would not have voted out if it was just a trading block and we can still work together on somethings.

    • Apple reportedly looks to blacklisted Chinese memory chips as RAM prices climb by Karthik Mudaliar Image via Apple Apple is reportedly trying to get a clearance from the Trump administration to buy memory from ChangXin Memory Technologies (CXMT) to get some relief from soaring DRAM prices. As per a report by the Financial Times, Apple approached the Commerce Department more than a month ago and also spoke to other officials and allies in Washington. For starters, CXMT is a company that's already been placed on the Pentagon's list of Chinese military companies. The Chinese company is the country's top DRAM maker. For Apple, the timing is certainly awkward but not surprising. Tim Cook had recently warned that Apple would have to raise prices because AI companies are buying up large amounts of memory for data centers, and just like that, Apple raised MacBook and iPad prices. Micron also recently revealed that customers have committed billions of dollars to secure memory supply years in advance, which shows us how aggressive securing infrastructure has become. This gives suppliers such as Samsung, SK Hynix, and Micron more leverage, while pushing hardware makers to look for alternatives. CXMT is one of those alternatives, but not the simplest one. Apple has spent many years trying to diversify parts of its supply chain away from China, especially for final assembly, while still depending heavily on Chinese manufacturing and suppliers. Even domestic brands from China are moving towards CXMT and YMTC instead of relying on Samsung, Micron, and SK Hynix. For Apple, though, it would invite more scrutiny than local Chinese companies. For now, this is more like a lobbying effort rather than a confirmed supply deal. There's no official statement from either of the parties. What is clearer, though, is the pressure behind such a request. AI demand has certainly made hardware a bottleneck, and companies are trying everything they can to bring things back to normal, even if that means making politically sensitive choices.
