NASA has set 6 March as the earliest possible launch date for Artemis II, the first crewed flyby mission to the Moon in more than 50 years.
Lori Glaze, a senior official with the US space agency, cautioned that pad work, a flight readiness review and a dress rehearsal analysis needed to be completed in order to meet that date.
"We need to successfully navigate all of those but assuming that happens, it puts us in a very good position to target 6 March," Ms Glaze said.
NASA rehearsed the launch of its massive SLS rocket yesterday.
Technical problems in early February cut short an earlier so-called wet dress rehearsal of the launch of the Artemis II mission.
However yesterday, the US space agency reported that things proceeded as planned, concluding at "T-29 seconds" in the countdown.
The wet dress rehearsal is conducted under real conditions - with full rocket tanks and technical checks - at Cape Canaveral in Florida, with engineers practicing the manoeuvres needed to carry out an actual launch.
The setback in February, which included a liquid hydrogen leak, dashed hopes of a lift-off this month.
Three American astronauts and one Canadian make up the Artemis II crew.
