Stem Cells

in spaaaaaaaace:

“Stem cells are inherently designed to remain at a constant number,” Zubair explains. “We need to grow them faster, but without changing their characteristics.”

The first phase of the investigation, he adds, is answering the question: “Do stem cells grow faster in space and can we grow them in such a manner that they are safe to use in patients?”

Investigators will examine the space-grown cells in an effort to understand the mechanism behind microgravity’s effects on them. The long-term goal is to learn how to mimic those effects and develop a safe and reliable way to produce stem cells in the quantities needed.

Just once, it would be nice to discover something that can be done in space that can’t be later mimiced on the ground. I hope that Made In Space has found one.

And of course, as I point out in the book, this kind of research could be accelerated if they added one more crewperson to ISS. The only reason they haven’t is lifeboat requirement, something that doesn’t exist in Antarctica.

Trump’s NASA Proposal

Loren Grush has the details.

This is just a proposal; as she notes, Culberson is likely to restore the Europa lander. And in general, the White House proposes, and Congress disposes. What really matters is what gets appropriated.

The Planetary Society

Entirely not unexpectedly, they have some terrible suggestions for Trump and NASA:

  1. Maintain the exploration of Mars as the organizing principle for NASA’s human spaceflight program
  2. Direct NASA to plan an executable, affordable path for sending humans to Mars orbit by 2033
  3. Expand NASA’s highly successful science portfolio
  4. Continue to grow and support the commercial space industry
  5. Initiate annual five percent increases to NASA’s budget for five years

The only good one is the fourth. Here are mine:

  1. Make the continuous reduction of the cost of space activities the organizing principle for NASA’s human spaceflight program
  2. Direct NASA to end development of its own launch systems and to start to procure propellant in LEO to enable trips beyond
  3. Expand NASA’s science portfolio with data purchases
  4. Continue to grow and support the commercial space industry
  5. Direct funding from SLS/Orion to support 1-4

Wasteful Spending

Trump is going to order a government-wide review of it.

[Update a while later]

Congratulations to Altius Space Machines for their NASA SBIR Phase II win for cryo propellant transfer technology development. If we canceled SLS/Orion, we could found several thousand efforts like this.
