SpaceX Almost Ready to Start Testing SN3 -- The Third Starship Prototype
Arthur T Knackerbracket has found the following story:
[Editor's note: SN3 is SpaceX parlance for "Serial Number 3"; Elon Musk is not just working on building rockets, he's building an assembly line and plans to build one Starship a week. This helps explain the use of serial numbers. --martyb]
For almost a year now, SpaceX has been building a series of Starship prototypes that will test how the system fares when launched to orbit.
[...] Musk recently shared images of the components for the SN3 prototype undergoing assembly.
Shortly after these images were shared, the assembled components were seen on their way to the company's test facility at Boca Chica, Texas, on the morning of March 29th. They were then seen being transferred to the launch pad by roll-lift and crane as of late afternoon. Footage of both these events was captured by the LabPadre and shared via Twitter.

Like its predecessors, the next step for the SN3 will be cryogenic loading trials in which the spacecraft's methane and oxygen tanks will be filled with a cryogenic liquid (most likely liquid nitrogen).
[...] In a previous statement, Musk announced that the SN3 would be used for static fire tests and short flights, whereas longer test flights will wait for the SN4. [...] There is [...] documentation that indicates that SpaceX will be conducting tests as early as next week.
The documents, which were shared on NASASpaceFlight, reference a permit issued by the Federal Aviation Administration (FAA) for the "Starhopper" vehicle, which is valid until June 2020. They further suggest that a static fire of the SN3's engines could take place between April 1st and 3rd, followed by a 150-meter (500 ft) hop test between April 6th and 8th. This was the maximum height achieved by the Starship Hopper.
[...] Once the Starship is finished and integrated with the Super Heavy booster, Musk hopes to begin conducting payload runs to the moon by 2022, followed by crewed missions to the surface by 2024. In between, Musk also intends to conduct the first lunar tourism mission (#dearmoon), which will involve sending a crew of artists around the moon in 2023.
