Greetings Starvoyagers!

Recently we had our Space Briefing about the Moon, this brief will be about the amazing class of rockets called Silver Darts. Especially the E subtype, carrying a small science probe. Its capable of reaching the Moon with its 13.700 dV. As such its been a common sight at the launchpad, and is able to perform a range of different missions, from lunar orbits and impacts, to geostationary positioning and polar orbits. All depending on the cargo, and the upper stage modifications.

Fact Card

Name Silver Dart E
Weight 179t
Total dV 13.700
dV In orbit 4.100
TWR 3,04

The E type is built with 4 stages:

  • Main (+4 boosters)    (3+4 * LR89 engines)
  • Circulation Stage (1 * LR105 engine)
  • Transfer Stage (1 * AJ10 (mid))
  • Probe ( 4 * RCS Quad (69/111 N class))

The Main stage can lift the rocket right out of the atmosphere to the desired apoapsis of 250km, at which point the Circulation stage takes over and speeds the rocket up to orbital speeds.

A TWR of 3 is unheard off in rocket design, but given the aerodynamics features. It performs well, reaching orbit in record time.

Overall its a brilliant design, the top of the line for its time. By using the thrust-plate with multiple nodes and 3 LR89 engines, this design is able to cut 80t of mass off earlier designs.
