Less than 0.6 tonnes (1,300 lb) Ballistic coefficient: Less than 35 kg/m 2 (7.2 lb/sq ft) ... and second was the Mars sample return mission planned for 1975.
The InSight mission to Mars launched with a C 3 of 8.19 km 2 /s 2. [5] The Parker Solar Probe (via Venus) plans a maximum C 3 of 154 km 2 /s 2. [6] Typical ballistic C 3 (km 2 /s 2) to get from Earth to various planets: Mars 8-16, [7] Jupiter 80, Saturn or Uranus 147. [8] To Pluto (with its orbital inclination) needs about 160–164 km 2 /s 2.

In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
Mars 6 was launched by a Proton-K carrier rocket with a Blok D upper stage, flying from Baikonur Cosmodrome Site 81/23. [3] The launch occurred at 17:45:48 UTC on 5 August 1973, with the first three stages placing the spacecraft and upper stage into a low Earth parking orbit before the Blok D fired to propel Mars 6 into heliocentric orbit bound for Mars.
He said the Senate currently is budgeting $200 million for ongoing development of the Mars Sample Return mission in NASA's fiscal 2025 budget. The House number is $600 million. Whatever number is ...
Ballistic capture was first used by the Japanese spacecraft Hiten in 1991 as a method to get to the Moon. [3] [4] [5] This was designed by Edward Belbruno and J. Miller. [3] [5] The ballistic capture transfer that performed this is an exterior ballistic capture transfer since it goes beyond the Earth-Moon distance. An interior ballistic capture ...
