You can now learn Klingon with Rosetta Stone, apparently.

However, Kzinti still isn't taught, yet.....

Panzergranate was referring to the Chinese lack of concern about customer satisfaction and their penchant for corruption, leading to "tofu dregs construction."  We still experience poorly manufactured crap in our stores.  We know they do some things right, like the 3 Gorges Dam.  If it were made like an ordinary infrastructure project, it would have killed millions of people, by now.  As it is product of hubris, to begin with, the dam is damned to collapse, before its time.

IFT4 now showing as April 2024 (no day of the month).  Lets see if the FAA will issue another license that quick.

Now showing as May 2024.  Either they expect delays due to needed modifications to address the issues revealed or more time for the FAA to be satisfied (maybe both).

I'm prone to be extremely critical of Musk, but I suppose "eventually" is key to that claim.  Saturn's LEO payload for the Apollo lunar missions was 140 tons for CM, LEM and fuel fifty years ago, so 200 tons seems doable.... eventually.

Don't forget that you lose a significant amount of payload by going for reusable.  Also potentially lowering cost/kg significantly. 

Musk might be well advised to keep the current size for rockets that need to be fully refueled in orbit and the larger size for orbital cargo and fuel deliveries.  200+ tons of fuel delivered by a V3 to a V2 configuration could refuel it in 6 missions (1200 tons fuel if dry).

Seems that the date may be/may have slipped to June.  Looks like the IFT3 mishap report hasn't been filed with NASA yet.

Crewed Starliner launch is planned for May 6th.  Best of luck to the astronauts but I wouldn't fly in it.

Due late Monday evening.  Lets hope for the best.  I haven't heard when the return flight will occur but that is where the last flight had the big failures and ended up on the final (of 3) backup on two important systems.  Also the parachute harness redesign, I haven't heard how they tested it (or if).  Boeing is no longer inspiring confidence in me.

Delayed a day.  Valve issues on the booster.

Update:  Delayed at LEAST till Friday. 

Mission length approximately 1 week. 

Further Update:
Now at least May 17th. 

Another Update:

May 21st  (Tuesday)

Yet Another Update:

Saturday May 25th.  Due to a helium leak on a thruster in Starliner.

Do you think that Voyager 1 would still be running if it had been made in China?? 

With the technology they had in 1977?  Of course not.  It wouldn't have made it to orbit let alone where it is.

Falcon 9 now having achieved 20 flights for a booster is planning to be validated for 40 flights. 

The Orion capsule that flew on Artemis I?  It has now been revealed that its heat shield took far more damage than predicted.  Enough that it COULD result in a loss of a future vehicle and crew.  Looks like some more delay with Orion regardless of what happens with HLS.

Ariane 6 looks like it might fly in June or July.

SHOCK!
