Utilizing an optimized, expendable Starship would possibly cut back the variety of tanker missions required by as much as 50 p.c. The are downsides, together with a major improve in prices and an undermining of the entire level of Starship: full and fast reuse.

It's secure to say that Starship would be the largest human spacecraft to land on the Moon by far.

There's a third draw back, and that is maybe an important one. An “expendable” Starship plan can be anathema to the management of SpaceX, together with founder Elon Musk. Officers there don't imagine the area trade has totally digested how Starship will remodel the launch trade.
“You don't but perceive what number of Starship launches will occur,” a senior SpaceX supply instructed Ars.
The corporate is aiming to launch 1 million tons of payload to orbit per 12 months, nearly all of which will likely be propellant. SpaceX merely believes that after it locks in on Starship operations, launching a dozen or many extra rockets monthly gained't be a giant deal. So why waste time on expendable rockets? That period is over.
Enter the Dragon
A second choice can be to rely solely on SpaceX {hardware}.
I don't anticipate NASA to have an interest on this concept, however it's price discussing. Practically a 12 months in the past, within the quick aftermath of the presidential election, Republican area officers had been contemplating canceling Artemis and substituting a “competitors” much like the Industrial Cargo program. It was thought that each SpaceX and Blue Origin would bid plans to land people on the Moon and that NASA would fund each.
These plans have largely fallen by the wayside within the final 12 months, although. NASA (and maybe most significantly, paymasters in Congress) favor to stay with the House Launch System rocket and Orion spacecraft for the preliminary Artemis missions.
But when pressed, SpaceX may give you a simplified Moon touchdown structure that requires fewer refuelings. There are a number of methods this might be accomplished, so I'll provide only one variant right here:
