NASA Mulls Soyuz Needs As Commercial Crew Schedule Remains Fluid
Posted: October 4, 2019 10:48 pm ET | Last Updated: October 4, 2019 10:48 pm ET | Find out what ISS program manager Kirk Shireman said on October 4, 2019 about the commercial crew schedule and whether NASA needs to buy more Russian Soyuz seats.
Starships should stay on Mars
There is an ever-recurring idea that Starships have to return to Earth to make colonization of Mars viable. Since Elon has announced the switch from carbon fiber to plain stainless steel I'm wondering whether it will be necessary to fly back such "low-tech" hardware. (By "low-tech" I mean relatively low-tech: no expensive materials and fancy manufacturing techniques.) In the early phase of colonization, most ships will be cargo-only variants. For me, a Starship on Mars is a 15-story tall airtight building, that could be easily converted into a living quarter for dozens of settlers, or into a vertical farm, or into a miniature factory ... too worthy to launch back to Earth. These ships should to stay and form the core of the first settlement on Mars.Refueling these ships with precious Martian LOX & LCH4 and launching them back to Earth would be unnecessary and risky. As Elon stated "undesigning is the best thing" and "the best process is no process". Using these cargo ships as buildings would come with several advantages: 1. It would be cheaper. It might sound absurd at first, but building a structure of comparable size and capabilities on Mars - where mining ore, harvesting energy and assembling anything is everything but easy - comes with a hefty price tag. By using Starships on the spot, SpaceX could save all the effort, energy, equipment to build shelters, vertical farms, factory buildings, storage facilities, etc. And of course, the energy needed to produce 1100 tonnes of propellant per launch. We're talking about terawatt-hours of energy that could be spent on things like manufacturing solar panels using in situ resources. As Elon said: "The best process is no process." "It costs nothing." 2. It would be safer. Launching them back would mean +1 launch from Mars, +3-6 months space travel, +1 Earth-EDL, +~10 in-orbit refuelings + 1 launch from Earth, + 1 Mars-EDL, Again, "the best process is no process". "It can't go wrong." 3. It would make manufacturing cheaper. Leaving Starships on Mars would boost the demand for them and increased manufacturing would drive costs down. 4. It would favor the latest technology. Instead of reusing years-old technology, flying brand-new Starships would pave the way for the most up-to-date technology.

Interesting data on 301 stainless at cryogenic temperatures.
Found a pretty good paper on the strength of various stainless steels at cryogenic temperatures.Page four has a good graph of the data on 301, but other grades are discussed. The increase in strength is pretty dramatic. Temps are also keyed to the boiling point of methane and oxygen (along with other common cryo fluids). The strength increase is more dramatic than I anticipated.

How will Starship's re-entry tiles handle metal-expansion?
From my limited understanding, the heat-dissipating re-entry tiles will be bonded to a steel hull. That hull will be cryo-cooled by the fuel on liftoff, and will then heat up to something on the order of 900°C during re-entry. Since steel expands when heated, wouldn't that expose gaps between the tiles? Is this an issue, and if so, how is it addressed in the design?

NASA may ask SpaceX to extend duration of Crew Dragon test flight
NASA astronauts Bob Behnken and Doug Hurley may spend more time on the International Space Station than originally planned when they ride SpaceX’s new human-rated Dragon spacecraft into orbit on its first crewed test flight, a space agency official said Friday.

I can confirm that SpaceX currently plans to launch SAOCOM 1B from Cape Canaveral instead of Vandenberg. This will be the first use of the southern polar corridor to reach orbit from the Cape since 1960.

Should SpaceX Hold Off Mars Missions for "Planetary Protection"?

"While the article has valid points, I think the article misses the main point in going to Mars....it is not the "thrill and feelings of hope".....it is for "human spices protection"....in case Earth ....runs into big trouble.Yes human migration has caused death and environmental disruption over thousands of years of human existence. Yes reasonable precautions make sense but to think freezing things as they are now is the answer .... falls way short.Thoughts
