  • It went from 1 pound air loss per day to 2 pounds per day.

    So it is significant in the statistics sense. That is a very measurable and sudden change which definitively shows that either a new leak has occured, or an existing leak has suddenly worsened.

    However, 2 pounds per day loss is not severe on its own. Presumably the worry is that without knowing what caused the sudden increase, they can’t know whether a sudden and much worse intensification of losses will occur. So the astronauts not involved in repair activities should be ready to evacuate until the situation is fully evaluated and a repair plan is ready.

    Oxygen generators recycle CO2 back into O2. They can’t create new air. So lost air is replaced from compressed gas storage tanks that get replenished from supply flights. 2 pounds per day is easy to supply from the tanks. The issue here is not knowing why there is a sudden doubling of losses and therefore lacking confidence that the situation won’t worsen rapidly.


  • Bad headline from the Guardian on this one.

    There’s a big difference between evacuation readiness and evacuation.

    There was a sudden, but not catastrophic increase in air loss from 1 pound per day to 2 pounds per day. Until the source of the loss increase is found, NASA doesn’t know if this is new damage such as from a micrometioroid impact or if existing damage is growing. Like a leaking dam, damage in weakened metal can grow rapidly without warning. So the astronauts not involved in the repair efforts are ordered to be ready for evacuation if the situation starts worsening rapidly.

    I personally expect the source of the leak to be found and repaired without evacuation.

    I wish inverter type microwaves were standard. The vast majority of residential microwave ovens only modulate on like a 10 second interval. So you put it on power setting 3 or 30 and it will pump out full power for 3 seconds then off for 7 seconds. This works for things like defrosting meat, but a bunch of foods will still start popping and drying out in those few seconds. Inverter microwaves modulate many times a second so they can warm much more fragile foods without searing them.







  • A while ago, I saw a post recommending people who wanted to try planting milkweed to use a tool that lists nurseries that source local seeds rather than ordering from a national place. This suggestion was made because many plants are fairly well tuned to their local climate. Even if you don’t intend to plant milkweed, I think this is a good tool to find a semi local supplier that cares about local heritage breeds. Most of the ones I checked take online orders and will ship. I’ll shoutout Southern Exposure Seed Exchange and Sow True Seeds.

    The other resource I really love is a college near us has a good botany program and they put on two plant sales a year. Their prices are good, but the quality and selection is what really stands out. Plus most of the volunteers are students or faculty so when you have questions they either have a good answer or can walk you over to someone who does. That hasn’t always been my experience at nurseries. I think it would be worth checking if any universities somewhat near you have a horticulture extension office or public gardens program. Try searching for botanical gardens in your preferred maps app and see what shows up.

    One last recommendation that perhaps doesn’t fit a houseplants community, but you got me monologing… John Scheepers/Van Engelen is my go to supplier for flowering bulbs. They import direct from holland and ship out to customers very quickly after the container arrives. The quality and size of bulbs I’ve gotten from them greatly surpasses any retail place I’ve tried.
