In one or more embodiments, a multi-axis articulated solar light shade that protects elements of a space-based sensor from direct solar illumination includes a base; a partial conical baffle tube having a first end portion, a second end portion, an elongated curved portion defining a shade between the first and second end portions, and an opening defined in an interior of the elongated curved portion, the first end portion rotatably attached to the base; and a visor pivotably attached to the second end portion. The partial conical baffle tube may be selectively rotated about a sensor line-of-sight in response to the sun's position relative to the sensor line-of-sight; and the visor may be selectively pivoted relative to the partial conical baffle tube in response to the sun's position relative to the sensor line-of-sight so as to protect the sensor from the direct solar illumination at any given time or any given orbital position.

1. A multi-axis articulated solar light shade, the light shade comprising: a base;a tapered partial conical baffle tube having a first end portion, a second end portion, an elongated curved portion defining a shade between the first and second end portions, and an opening defined in an interior of the elongated curved portion, the first end portion rotatably attached to the base; anda visor pivotably attached to the second end portion. 2. The light shade of claim 1, further comprising: a motor configured to rotate the partial conical baffle tube relative to the base. 3. The light shade of claim 1, further comprising: a motor configured to pivot the visor relative to the partial conical baffle tube. 4. The light shade of claim 3, further comprising: a pushrod attached to the visor, wherein the motor is configured to drive the pushrod to pivot the visor relative to the partial conical baffle tube. 5. The light shade of claim 1, wherein the elongated curved portion of the partial conical baffle tube comprises a tapered or conical configuration. 6. The light shade of claim 2, wherein the motor is arranged in the base. 7. The light shade of claim 3, wherein the motor is arranged in the base. 8. A method of protecting elements of a space-based sensor from direct solar illumination by using a multi-axis articulated solar light shade comprising a tapered partial conical baffle tube and a visor attached to an end portion of the partial conical baffle tube, the method comprising: selectively rotating the partial conical baffle tube about a sensor line-of-sight in response to the sun's position relative to the sensor line-of-sight; andselectively pivoting the visor relative to the partial conical baffle tube in response to the sun's position relative to the sensor line-of-sight,wherein the partial conical baffle tube is selectively rotated and the visor is selectively pivoted so as to protect the sensor from the direct solar illumination at any given time and any given orbital position. 9. The method of claim 8, wherein selectively rotating the partial conical baffle tube comprises selectively rotating the partial conical baffle tube about the sensor line-of-sight in response to a polar angle of the solar illumination relative to the sensor. 10. The method of claim 9, wherein selectively pivoting the visor comprises selectively pivoting the visor relative to the partial conical baffle tube in response to a radial angle of the solar illumination relative to the sensor. 11. The method of claim 8, wherein selectively pivoting the visor comprises selectively pivoting the visor relative to the partial conical baffle tube on an axis perpendicular to the sensor line-of-sight. 12. A system for protecting elements of a space-based sensor from direct solar illumination, the system comprising: a space-based sensor comprising an optical element; anda light shade comprising:a base; a tapered partial conical baffle tube having a first end portion, a second end portion, an elongated curved portion defining a shade between the first and second end portions, and an opening defined in an interior of the elongated curved portion, the first end portion rotatably attached to the base; anda visor pivotably attached to the second end portion,wherein the light shade is located around an aperture of the optical element and arranged to protect the optical element from the direct solar illumination. 13. The system of claim 12, wherein the optical element comprises a telescope. 14. The system of claim 12, further comprising: a processor configured to receive one or more inputs relating to the sun's position relative to a sensor line-of-sight and in response thereto, to provide one or more output signals to one or more motors that either selectively rotate the partial conical baffle tube about the sensor line-of-sight, or selectively pivot the visor relative to the partial conical baffle tube, or both. 15. The system of claim 14, further comprising: a memory containing pre-programmed information stored therein regarding the sun's position relative to the sensor line-of-sight. 16. The system of claim 14, wherein the one or more inputs comprise an input from a sun position sensor.
