TMK-1

TMK-1
Description
Role: Mars Expedition
Crew: three
Dimensions
Height: 39 ft 12 m
Diameter: 19.60 ft 6 m
Volume:
Rocket engines
Main Engine (Lox/Kerosene) :
Performance
Endurance: 1095 days

The first flight to Mars of the TMK-1 was planned to begin on June 8, 1971.

The 75 metric ton TMK-1 spacecraft would take a crew of three on a Mars flyby mission. After a 10.5 month flight the crew would race past Mars, dropping remote controlled landers, and then be flung into an earth-return trajectory. Earth return would happen on July 10, 1974, after a voyage of three years, one month, and two days.

Spacecraft configuration:
  • A habitation or pilot compartment, with an internal volume of 25 cubic meters
  • A work or equipment section, including the hatch for extra-vehicular activities and a solar storm shelter should solar flares increase radiation to dangerous levels. Total volume of the section 25 cubic meters
  • A biological systems compartment, with the SOZh closed-cycle environmental control system, with a total volume of 75 cubic meters
  • A aggregate section, with the Mars probe capsules, the KDU midcourse correction engine, the SOZh solar concentrator and solar panels, and radio antennas
  • The SA crew earth re-entry capsule, about 4 m in diameter

TMK-E

TMK-E
Description
Role: Mars Expedition
Crew: six
Dimensions
Height: 574 ft 175 m
Diameter: 19.60 ft 6 m
Volume:
Electric engines
Main Engine (Xenon) : 74 N 17 lbf
Performance
Endurance: 1000 days

This variation was proposed in 1960, and consisted of a complete Mars landing expedition to be assembled in Earth orbit using several N1

 launches. The spacecraft would be powered by nuclear electric engines and five landers would deliver a nuclear-powered Mars Train on the surface for a one-year mission.

The TMK-E would be capable of a three-year flight to Mars and return, of which one year was powered flight.
It would measure 175 m in length and house a crew of six. Six landing craft were included, two for the crew and four for the Mars Train vehicles.

Mavr (MArs - VeneRa)

Mavr
Description
Role: Venus Expedition
Crew: three
Dimensions
Height: 82 ft 25 m
Diameter: 19.60 ft 6 m
Volume: 45.00 m3
Rocket engines
Main Engine (Lox/Kerosene) :
Performance
Endurance: 680 days

A variation of the TMK mission planning involved a flyby of Venus on the return voyage, and was given the code name "Mavr" (MArs - VeneRa), meaning Mars - Venus.

KK - Space Complex for Delivering a Piloted Expedition to Mars

KK - Space Complex for Delivering a Piloted Expedition to Mars
Description
Role: Mars Expedition
Crew: three
Rocket engines
Main Engine (Xenon) : 14 lbf ea 61 N
Performance
Endurance: 630 days 30 days Mars stay

In 1966, a final version of the TMK studies was known as KK - Space Complex for Delivering a Piloted Expedition to Mars. Nuclear electric propulsion was to be used for the 630 day mission. The craft structure consisted of:
  • EK - Expeditionary spacecraft: command center for piloting in interplanetary space
  • OK - Orbital Complex: living and work compartments and the life support systems
  • SA - The Landing Module, AV - The Ascent Module and RV - The Ascent Rocket stage
  • PS - The Planetary Station: used by the expedition on the Martian surface for life support and scientific research


The launch was planned for 1980, with a crew of three cosmonauts. Mars stay duration would be 30 days.

Mission data:
  • Total Payload Required in Low Earth Orbit-metric tons: 150
  • Total Propellant Required-metric tons: 24
  • Number of Launches Required to Assemble Payload in Low Earth Orbit: 2
  • Launch Vehicle: N1
