Because the first stage booster called the Super Heavy has 35 engines, the speculation is that it wouldn’t be ready for an October launch so the orbital launch Elon is referring to must be an SSTO using the Starship only.
Elon Musk says SpaceX’s Starship can land on the moon by 2021.

Drs. Gil Levin and Patricia Straat were interviewed on The Space Show Saturday:
ESA's Callisto reusability testbed as an *operational* TSTO and SSTO.
Key questions that need to be answered for this to be feasible:
1.)What's average Isp with altitude compensation?
The latest NASA budget suggests the Europa Clipper, an orbiter mission to the Jovian-system to study Europa, won’t fly on the SLS, but instead on commercial rockets:
However, instead of just an orbiter mission, by using...
The idea is discussed here:
But the article seems to be saying contradictory things. It is both positive and negative towards the idea. Also, I can’t tell if the FH carrying the Orion...
Wikipedia gives the propellant mass for the Ariane 6 core as 140 tons compared to the 170 tons of the Ariane 5, while they have the same diameter of 5.4 m so I assumed it would be shortened. Wiki doesn't give the core stage length for the Ariane 6.

NASA has just announced they want to send manned flights to the Moon within 5 years. The plan has been to use the SLS for such flights as a launcher comparable in payload to the Saturn V, ca. 130 tons to LEO. The problem is this would require the Exploration Upper Stage(EUS) for the SLS, a large...

Thanks for the link on the Callisto. It will be quite small at 15 meters long and 1 meter in diameter. Since it will be hydrolox propellant that means less than 4 tons propellant load.
That's far too small for the Vulcain engine. Perhaps they will use the HM7B hydrolox upper stage engine. It...
