6. The system of claim 5 , herein the sample capture assembly further comprises a container movement assembly operably coupled to the chamber, the container movement assembly being operably to insert the container into the chamber and remove the container when a sample has been deposited in the container.

7. The system of claim 5 , wherein the chamber is disposed in a sample testing device, the sample testing device being at least one of a mass spectrometer, a gas chromatograph, and a laser spectrometer.

8. A method of acquiring and delivering a sample comprising:

directing pressurized gas into a hollow interior of a sampler device, the hollow interior having a curved and angled surface with an open end and an exit end, the open end being in proximity to a surface containing the sample, the pressurized gas being directed by a plurality of nozzles mounted to the curved and angled surface, a first nozzle of the plurality of nozzles having a first spray angle and directing the pressurized gas into the exit end, a second nozzle of the plurality of nozzles having a second spray angle and directing a first portion of the pressurized gas toward the open end and a second portion of the pressurized gas towards the exit end, the first spray angle being smaller than the second spray angle;

flowing a portion of the sample through the exit end with the pressurized gas; and

receiving the portion in a container fluidly coupled to the exit end.

9. The method of claim 8 , further comprising flowing the pressurized gas through a filter after receiving the portion in the container, then exhausting the pressurized gas to the environment.

10. The method of claim 9 , further comprising moving a flap coupled to the container with the pressurized gas prior to receiving the portion in the container.

11. The method of claim 10 , further comprising moving the container from a first position into a second position, the container receiving the sample in the second position.

12. The method of claim 11 , further comprising moving the container from the second position to a third position after receiving the sample.

13. The method of claim 8 , wherein the directing of the pressurized gas includes directing at least a first portion of the pressurized gas towards the exit end.

14. A sample acquisition and delivery system for an interplanetary vehicle, the system comprising:

a gas delivery assembly having a storage tank with a compressed gas;

a sampler device having a hollow interior, the hollow interior having a curved and angled surface, an open end and an exit end;

a plurality of nozzles fluidly coupled to the curved and angled surface, at least a first nozzle of the plurality of nozzles having a first spray angle and arranged to direct the compressed gas towards the exit end, at least a second nozzle of the plurality of nozzles having a second spray angle and directing a first portion of the compressed gas towards the open end and a second portion of the compressed gas towards the exit end, the first spray angle being smaller than the second spray angle;

a sample capture assembly having a container distally located from the exit end; and
