SpaceX Starship 120m rocket full Stacked Testing, 33 engines static fire on the way...

For the first time in more than seven months, SpaceX has just kicked off the most ambitious round of tests for its fully stacked launch system ahead of its debut orbital launch attempt as soon as later this year.

The testing started in earnest on Oct 25 with some partial cryo testing on the Booster 7/Ship 24 full stack. The tests where the flammable propellant was replaced with a similarly cold (cryogenic) fluid that’s similar enough to subject a rocket to similar thermal and mechanical stresses - on the Starship full stack.
As expected, on the next day, more cryo testing with the full stack Booster 7/Ship 24 was underway!

Well, though this test SpaceX subjected Starship to was by no means ambitious, the first test of the first fully integrated prototype of a new rocket to fly into orbit is still an immensely significant achievement – particularly so for the largest rocket ever built.

Beyond the basic mechanical demonstration that Super Heavy Booster 7 is strong enough to support a partially loaded Starship, which probably wasn’t in doubt, it’s likely that the main purpose of this first full-stack cryoproof was to ensure that all the systems required to fuel Starship on top of Super Heavy were working as expected. That’s no small feat given that Starship is both the tallest rocket and largest upper stage ever assembled. To fully fuel a Starship for an orbital launch, around 1200 tons of propellant (or LN2 for a cryoproof) – equivalent to the weight of more than two entire Falcon 9 rockets – must be pumped around 85 meters up Starbase’s integration tower.
