Message to Edit: HTML is ON UBB Code is ON Smilies Legend	Originally posted by Robert Pearlman on 02-20-2026 06:30 PM The SLS core stage is rated for 22 cryogenic recycles. <BLOCKQUOTE>[i]The liquid hydrogen tank shrinks about 6 in. (15 cm) in length and 1 in. (2.54 cm) in diameter when filled with cryogenic fuel. The liquid oxygen tank shrinks approximately 1.5 in. (3.8 cm) in length and 0.5 in (1.3 cm) in diameter when filled. To compensate, everything that attaches to them – ducts, vent lines, systems tunnel, brackets, etc. – is connected by accordion-like bellows sections, slotted joints, telescoping sections, or ball joint hinges.[/i]</BLOCKQUOTE>
