1. A multi-layer insulation (MLI) comprising: a plurality of sealed metalized volumes in a stacked arrangement, the plurality of sealed metalized volumes encapsulating a gas therein, the gas having one of a thermal insulating property, an acoustic insulating property, or a combination insulating property thereof;at least one first spacer between adjacent sealed metalized volumes of the plurality of sealed metalized volumes, wherein the at least one first spacer is outside of each of the plurality of sealed metalized volumes;at least one second spacer within at least one of the plurality of sealed metalized volumes; anda protective cover surrounding the plurality of sealed metalized volumes, wherein the protective cover defines an interior space that contains the plurality of sealed metalized volumes and the at least one first spacer, and wherein the protective cover retains one of the gas or another gas within the interior space around the plurality of sealed metalized volumes and the at least one first spacer. 2. The MLI of claim 1, further comprising a plurality of second spacers, wherein at least one of the plurality of second spacers is within each of the plurality of sealed metalized volumes. 3. The MLI of claim 1, wherein the plurality of sealed metalized volumes comprise metalized plastic film layers sealed together, the metalized plastic film layers having a metalized surface, wherein the metalized surface is positioned on an exterior side of the plurality of sealed metalized volumes. 4. The MLI of claim 1, wherein the gas is one of Argon (Ar), Krypton (Kr), Xenon (Xe), Sulfur Hexafluoride (SF6), or a combination thereof. 5. The MLI of claim 1, wherein the plurality of sealed metalized volumes comprises one of Al-polyimide, Al-polyester, or aluminized plastic film with aluminum on one side thereof. 6. The MLI of claim 1, wherein each of the at least one first spacer and the at least one second spacer comprises a polyaramid, polyethylene terephthalate, polyimide material, or a combination thereof. 7. The MLI of claim 1, wherein the covers comprise at least one of beta cloth or polyaramid laminate material. 8. A method for providing a multi-layer insulation (MLI), the method comprising: disposing a first spacer within a sealed metalized volume;encapsulating a gas within the sealed metalized volume, the gas having one of a thermal insulating property, an acoustic insulating property, or a combination insulating property thereof;stacking a plurality of the sealed metalized volumes with a second spacer between adjacent sealed metalized volumes of the plurality of sealed metalized volumes, wherein the second spacer is outside of each of the plurality of sealed metalized volumes;surrounding the stacked plurality of sealed metalized volumes with a protective cover; andretaining one of the gas or another gas within an interior space of the protective cover that surrounds the stacked plurality of sealed metalized volumes, wherein one of the gas or another as are retained around the plurality of sealed metalized volumes and the second spacer. 9. The method of claim 8, further comprising using as the plurality of sealed metalized volumes a plurality of metalized plastic film layers sealed together, the metalized plastic film layers having a metalized surface, wherein the metalized surface is positioned on an exterior side of the plurality of sealed metalized volumes. 10. The method of claim 8, further comprising using as the gas one of Argon (Ar), Krypton (Kr), Xenon (Xe), Sulfur Hexafluoride (SF6), or a combination thereof. 11. The method of claim 8, further comprising using sealed metalized volumes formed form one of aluminum-polyimide, aluminum-polyester, or aluminized plastic film with aluminum on one side thereof. 12. The method of claim 8, further comprising using as the first and second spacer a material comprising one of polyaramid, polyethylene terephthalate, or polyimide and using covers formed from one of beta cloth or polyaramid laminate material. 13. An insulating blanket comprising: a plurality of sealed metalized volumes in a stacked arrangement, the plurality of sealed metalized volumes encapsulating a gas therein, the gas having one of a thermal insulating property, an acoustic insulating property, or a combination insulating property thereof;at least one spacer between adjacent sealed metalized volumes of the plurality of sealed metalized volumes, wherein the at least one spacer is outside of each of the plurality of sealed metalized volumes; anda protective cover surrounding the plurality of sealed metalized volumes to form a blanket having insulating properties from the plurality of sealed metalized volumes therein, wherein the protective cover defines an interior space that contains the plurality of sealed metalized volumes and the at least one spacer, and wherein the protective cover retains one of the gas or another gas within the interior space around the plurality of sealed metalized volumes and the at least one spacer. 14. The MLI of claim 1, wherein the MLI is devoid of any vent path. 15. The insulating blanket of claim 13, wherein the insulating blanket is devoid of any vent path.
