Good fun has started at the mouth of the Rio Grande

Looks like our boys are getting a well deserved rest day but by the look of the crane placements. Seem they’re going to have one busy day tomorrow and boy check out those buffs.😃📸🚀 pic.twitter.com/54VpThlnmg

#5 This is only a 3 or 4 Raptor engine device - test hopper - to evaluate the regime from ground to 5km. The Raptors are not the final form but the evaluation form and are much lower pressure (only 150 bar instead of 300 bar) and thrust. They are methane lox engines.
Diameter of rocket is close to 9 meters.

#6 It's a test form of the second stage of the Mars rocket.
The first stage will not be developed until the second is well on the way to perfected. The final form of the second stage will be capable of SSTO!

The first stage engine count will be huge. It keeps changing so no final count yet. Number of engine estimates for it run between 30 to 44.

#7 Have to redesign the bell of the engines to be more vacuum friendly for Martian operation, lower atmospheric pressure makes design pretty important. That will need to be tested in thinner air, probably boosted up then tested after ground level tests.
