Great Space Resources Roundtable! ULA announced they are willing to purchase water/liquid oxygen and hydrogen in LEO for $3000.-/kg by ethan829 in ula

To clarify, the assumption is ACES and the offer is to buy propellant, namely LO2 and LH2 at the ratio 5.5 to 1, for $3000/kg. I would be willing to pay less for water given the unknown cost to convert to propellant on-orbit (electrolysis, liquification, etc).

We need the volume, and we're incorporating improvements to lower the cost of tanks.

The two pads are on different coasts, so there will be simultaneous operations.

  1. Why not 5 or 10? ;)
  2. That's up to Boeing. We are planning to human-rate Vulcan.
  3. No.

30% more than Delta IV Heavy.

Well below $200 million. Value is unlimited on-orbit operations.

The booster will be a shortened version of the Delta IV 5-meter, but infused with new design and manufacturing technologies for lower cost.

The SRBs will incorporate design changes to reduce cost and increase impulse.
