change "Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere."

to "Rockets work more efficiently in a vacuum without incurring a loss of thrust due to the opposing pressure of the atmosphere."

to "Rockets lose thrust due to atmospheric friction and thus work more efficient in a vacuum." ^[1] Bwikizee (talk) 03:13, 7 January 2024 (UTC)[reply]

The wording is a bit clunky, how does this sound.

Rockets lose thrust due to atmospheric friction resulting in more efficient work in a vacuum.

It's not about aerodynamic drag/friction it's about pressure differences. It's because the supersonic exhaust jet punches through the atmosphere so ambient air pressure is no longer able to press on the inside of the engine nozzle while it's running. So there's a net backwards force equal to the exit plane area multiplied by the atmospheric pressure the whole time it's running. GliderMaven (talk) 17:40, 5 September 2024 (UTC)[reply]

Is this about a Rocket as a vehicle or a Rocket Engine

It is unclear if this is about a Rocket as a vehicle or a Rocket Engine which already has a separate page.

Most people would expect to see an article about a Rocket vehicle and then a short description of the Form Function and components. Jwilleke (talk) 09:10, 22 June 2024 (UTC)[reply]

semi-protected?

Article's history doesn't show edit war nor vandalism, what's the rationale for semi-protection? 2A01:E0A:1DC:4570:C4C8:F45F:BE6:361A (talk) 12:52, 3 December 2024 (UTC)[reply]
