Similarly, wheels RW1 and RW2 are included in the rear vertical visual field range BVV. Thereby, it is possible to confirm whether or not stones are sandwiched between the wheels RW1 and RW2. Further, as an example, both the front camera FC and the rear camera BC are in the field of view above the horizontal line L1.

FIG. 12 is a schematic diagram showing the field of view of the camera in the BB cross section of FIG. The right vertical visual field range RVV is a vertical visual field range of the right-side camera RC, and the left vertical visual field range is a vertical visual field range of the left-side camera LC. As shown in FIG. 12, the right vertical visual field range RVV includes wheels FW1 and RW1. Thereby, it can be confirmed whether or not stones are sandwiched between the wheels FW1 and RW1. Similarly, the left vertical visual field range LVV includes wheels FW2 and RW2. Thereby, it can be confirmed whether or not stones are sandwiched between the wheels FW2 and RW2. Further, as an example, both the right side camera RC and the left side camera LC are in the field of view above the horizontal line L2.

The resolution of the first camera such as the front camera FC and the rear camera BC is higher than the resolution of the second camera such as the right side camera RC and the left side camera LC. That is, the resolution of the camera in the traveling method (the method in which the wheel advances) is higher than the resolution of the side camera. Thereby, since the visual field range in the traveling direction can be seen with higher resolution, an obstacle or the like in the traveling direction can be easily found.

As shown to FIG. 13A, it can move to back and front, and as shown to FIG. 13B, it can turn on the spot. However, as shown in FIG. 13C, since the wheels FW1, FW2, RW1, and RW2 do not rotate in the left-right direction, the left-right movement cannot be performed. Instead, as shown in FIG. 13D, by moving 90 degrees on the spot and then moving back and forth, it is possible to move left and right as a result.

Here, the second camera controller CMC2 includes a second processor PC2.

Thus, the front camera FC is connected to the first processor PC1, and the rear camera BC is connected to the second processor PC2. That is, the front camera and the rear camera are connected to separate processors.
As a result, even if one of the first processor PC1 and the second processor PC2 fails and cannot operate, the other processor can operate. Therefore, either the front camera FC or the rear camera BC can be operated. Can be transferred to the ground station E.

The compressed data is transferred to the first communication controller CC1.
The first communication controller CC1 transmits the compressed data from the first antenna AT1 to the landing ship (lander) L. Thereafter, the compressed data is transferred from the lander L to the ground station E. Thereby, the moving image data photographed by the front camera FC and the right-side camera RC of the spacecraft R can be transferred to the ground station, and the operator who operates the spacecraft R can view the moving image data on the earth. Thus, the operator who operates the spacecraft R can see the image of the moon on the earth. According to this configuration, the front camera FC and the right-side camera RC do not need to be always turned on like the USB camera, and need only operate when requesting moving image data, thereby reducing power consumption. Can do.

FIG. 16 is a schematic diagram showing a hardware configuration of the second camera controller CMC2. As shown in FIG. 16, the rear camera BC is connected to an A / D converter AD3, and the A / D converter AD3 is connected to the serial interface SI2 of the second camera controller CMC2 via a flat cable.

Subsequently, the casing coating will be described with reference to FIGS. 17 and 18. FIG. 17 is a schematic diagram illustrating an outline of a cross section of the housing HS. As shown in FIG. 17, the housing HS includes a substrate 1, a metal film (here, a silver film) 2 deposited on the substrate 1, and a Teflon ( Registered trademark) layer 3. Here, the substrate is, for example, carbon fiber reinforced plastic (Carbon Fiber Reinforced Plastics: hereinafter referred to as CFRP). Thereby, sunlight is reflected by the metal film 2, and the heat of the housing HS can be emitted from the Teflon (registered trademark) layer 3 as infrared rays by radiation. Note that a quartz glass layer may be used instead of the Teflon (registered trademark) layer 3.

Further, the housing HS has an indium tin oxide (hereinafter referred to as ITO) layer 4 provided on the Teflon (registered trademark) layer 3. ITO is a transparent conductive film. Thus, by providing the ITO layer 4 on the Teflon (registered trademark) layer, it is possible to transmit sunlight and to allow the electric charge generated on the ITO to flow to the ground.

Next, a process related to coating of the casing will be described with reference to FIG. FIG. 18 is a flowchart illustrating an example of a process flow relating to coating of the casing on the front plate FP, the rear plate BP, the top plate TP, and the bottom plate DP.

(Step S101) First, the CFRP plate is processed. In the case of the front plate FP, for example, a CFRP plate is cut out to a predetermined size, and an opening for fitting a distance sensor is made. In the case of the rear plate BP, for example, CFRP is cut out to a predetermined size, and an opening for fitting the plate PL5 is made. In the case of the top plate TP, for example, CFRP is cut out to a predetermined size, and openings for fitting the plates PL1 to PL4 are made. In the case of the bottom plate DP, for example, CFRP is cut out to a predetermined size.

(Step S102) Next, silver is deposited on the CFRP plate in a vacuum.

(Step S103) Next, Teflon (registered trademark) powder is sprayed on the silver deposition surface. As a result, Teflon (registered trademark) particles on the beads adhere to the silver deposition surface.

(Step S104) Next, the temperature is raised and Teflon (registered trademark) is melted and baked. Thereby, the particles of Teflon (registered trademark) are melted and connected to each other, and the surface of the Teflon (registered trademark) layer becomes flat.

(Step S105) Next, ITO is deposited in vacuum. Thereby, the front plate FP, the rear plate BP, the top plate TP, and the bottom plate DP are obtained.

Subsequently, a process of creating the right side plate RP and the left side plate LP as side plates will be described with reference to FIGS. FIG. 19 is a schematic diagram showing the left side plate LP before coating. In the present embodiment, since the solar cells are arranged on the right side plate RP and the left side plate LP, the left side plate LP is provided with through holes H1 to H6 for drawing wirings connected to the solar cell into the housing HS. ing. In addition, although illustration is abbreviate | omitted, the through-hole for drawing in the wiring connected to a solar cell in the housing | casing HS is similarly provided in the left side plate LP.

FIG. 20 is a diagram illustrating an example of the configuration of the power controller PU. As shown in FIG. 20, the solar cells are connected in series for each column by wiring, and the wiring is drawn into the housing HS from, for example, the through holes H1 to H6 shown in FIG. Connected. Specifically, each wiring from the solar cell is connected to the anodes of the corresponding diodes D1 to D12 and rectified. The cathodes of the diodes D1 to D12 are respectively connected to the charge / discharge circuit CDC, and the current rectified by the diodes D1 to D12 is input to the charge / discharge circuit CDC. In this manner, the wiring from the solar cell is connected to the charge / discharge circuit CDC in the housing HS through the through holes H1 to H6 provided in the housing HS. With this configuration, it is not necessary to provide a space for fixing the wiring on the outer surface of the housing HS, so that many solar cells can be arranged within a limited area. The charge / discharge circuit CDC charges the battery BAT using the input current. The charge / discharge circuit CDC supplies power to other electronic devices using the power of the battery BAT.

FIG. 21 is a flowchart showing an example of a process of creating the right side plate RP or the left side plate LP which is a side plate.

(Step S201) First, CFRP is cut into a predetermined size, and a through hole is opened in the CFRP plate.

(Step S202) Next, the through hole provided in the CFRP plate is masked. Thereby, it can avoid that a through-hole is obstruct | occluded with the substance adhering by subsequent processes.

(Step S203) Next, silver is deposited on the CFRP plate in a vacuum.

(Step S204) Next, Teflon (registered trademark) powder is sprayed onto the silver deposition surface. As a result, Teflon (registered trademark) particles on the beads adhere to the silver deposition surface.

(Step S205) Next, the temperature is raised and Teflon (registered trademark) is melted and baked. Thereby, the particles of Teflon (registered trademark) are melted and connected to each other, and the surface of the Teflon (registered trademark) layer becomes flat.

(Step S206) Next, ITO is deposited in vacuum.

(Step S207) Next, the masking attached in Step S202 is taken.

(Step S208) Next, a heat-resistant and cold-resistant polyimide film is stuck on the ITO. The polyimide film is, for example, Kapton (registered trademark).

(Step S209) Next, the solar cell is fixed on the polyimide film. Thereby, the right side plate RP or the left side plate LP which is a side plate is obtained.

Then, the inclination of the surface of the housing | casing in which the solar cell is arrange | positioned is demonstrated. FIG. 22 is a schematic diagram of a front view of the probe R at a predetermined latitude where the probe R is arranged. As shown in FIGS. 2 and 22, the surface of the housing on which the solar cells are arranged (in this embodiment, the right side surface and the left side surface as an example) is inclined inward of the spacecraft R from the bottom plate DP to the top plate TP. ing. Thereby, since the light from the sun can be received efficiently, the power generation amount can be increased.
The right side surface and the left side surface, which are the surfaces of the housing where the solar cells are disposed, are inclined at an angle at which the power generation capacity from when the sun rises to when it sinks is maximized at the latitude where the spacecraft R is to be disposed. Yes. Specifically, as shown in FIG. 22, when the maximum elevation angle of the sun at the latitude where the spacecraft R is to be arranged is φ1 degree, the angle at which the power generation capacity from when the sun rises until it sinks is maximum is θ1. Therefore, the inclination of the right side surface and the left side surface from the horizontal plane is set to θ1 degree.

FIG. 23 is a schematic diagram of a front view of the spacecraft R when the latitude where the spacecraft R is to be arranged is higher than that in FIG. As shown in FIG. 23, the maximum elevation angle φ2 of the sun at the latitude where the spacecraft R is to be arranged becomes smaller than φ1. At this time, the angle at which the power generation capacity from when the sun rises until it sinks becomes θ2, which is larger than θ1, so the inclination of the right side surface and the left side surface from the horizontal plane is set to θ2 degrees.

On the other hand, FIG. 24 is a schematic diagram of a front view of the spacecraft R when the latitude where the spacecraft R is to be arranged is lower than in the case of FIG. As shown in FIG. 24, the maximum elevation angle φ3 of the sun at the latitude where the spacecraft R is to be arranged becomes larger than φ1. At this time, the angle at which the power generation capacity from when the sun rises until it sinks becomes θ3 smaller than θ1, so the inclination of the right side surface and the left side surface from the horizontal plane is set to θ3 degrees.

Thus, the inclination of the surface (here, the right side surface and the left side surface) of the casing on which the solar cell is disposed is determined according to the latitude at which the spacecraft R is to be disposed. Specifically, the higher the latitude at which the spacecraft R is to be arranged, the smaller the maximum elevation angle of the sun, so the inclination of the right side RP and the left side from the horizontal plane increases. Thereby, since the inclination of the solar cell is set according to the maximum elevation angle of the sun, the amount of power generation can be increased.

Subsequently, since the structures of the wheels FW1, RW1, and RW2 are the same as those of the wheels FW2, the structure for fixing the motor MT to the wheels FW2 as a representative of the wheels will be described with reference to FIGS.

FIG. 25 is an exploded perspective view of the wheel FW2. As shown in FIG. 25, the wheel FW2 includes a motor MT, a motor slave SV, a bearing BR1, a bearing spacer BS, a bearing BR2, a motor housing MH, a bearing hold plate BHP, a clamp HC, a hub HB, and a wheel WL2. The motor MT is inserted into the motor slave SV, the rotation shaft of the motor MT is inserted into the first hole HL in FIG. 26 of the hub HB, and the rotation shaft of the motor MT is clamped to the hub HB by the clamp HC.

FIG. 26 is a front view of the hub HB as seen from the direction of the arrow A1 in FIG. As shown in FIG. 26, it has the 1st hole HL and the notch CO connected to the said 1st hole HL. FIG. 27 is a cross-sectional view of the hub HB when cut along the DD cross section of FIG. As shown in FIG. 27, the hub HB has a cone-shaped projection PJ near the center. As described above, the hub HB has the cone-shaped convex portion PJ near the center, and communicates with the first hole HL in which the rotation shaft of the motor MT is fitted in the convex portion PJ and the first hole HL. Has cutout CO.

FIG. 28 is a cross-sectional view of the clamp HC taken along the CC cross section of FIG. In FIG. 28, the rotating shaft of the motor MT is inserted from the front surface FS side, and the hub HB is on the back surface RS side. As shown in FIG. 28, the clamp HC has a second hole HL2 whose diameter gradually decreases from the rear surface RS toward the front surface FS.

The convex portion PJ is fitted in the second hole HL2 with the back surface RS of the clamp HC and the hub HB facing each other. With this configuration, when the convex portion PJ is fitted into the second hole HL2, the notch CO is narrowed, the contour around the first hole HL of the hub HB is narrowed, and the rotation shaft of the motor MT is strongly restrained. . Thereby, it is possible to prevent the rotation shaft of the motor MT from slipping. Further, when the motor MT is fixed, if an excessive force is applied to the rotating shaft of the motor MT in the rotating shaft direction, the motor MT suddenly stops rotating. On the other hand, according to the above configuration, when tightening with the clamp HC, the hub HB does not move but moves only by the clamp HC, so that an excessive force in the direction of the rotation axis is not applied to the rotation shaft of the motor MT. Stop of sudden rotation of MT can be prevented.

In this embodiment, as an example, it is assumed that the exploration is not performed near the equator of the moon. However, the exploration may be assumed near the equator of the moon. In this case, the electronic device is not fixed to the top plate, but the electronic device may be disposed on the back surface of the front plate FP or the rear plate BP, or the electronic device may be disposed on the back surface of the bottom plate DP. Thereby, an electronic device can be provided on the back side of the surface where sunlight does not enter, and an increase in temperature of the electronic device can be prevented. Furthermore, the heat generated from the electronic device can be released from the top plate TP of the housing HS to the outer space to suppress the temperature rise of the electronic device.

In the present embodiment, as an example, both the front plate FP and the rear plate BP of the housing are inclined to the inside of the spacecraft R from the bottom plate DP to the top plate TP. Good.
Similarly, in the present embodiment, as an example, both the right side plate RP and the left side plate LP of the housing are inclined inward of the spacecraft R from the bottom plate DP to the top plate TP, but only one of them is inclined. Also good.

In the present embodiment, as an example, the wheel FW1 is included in both the field of view of the front camera FC that is one of the first cameras and the field of view of the right-side camera RC that is one of the second cameras. However, the present invention is not limited to this, and the wheel FW1 may be included only in one field of view. The same applies to the other wheels FW2, RW1, RW2. In this way, it is only necessary to see the wheels with at least one of the cameras. Thereby, it can be confirmed whether the wheel is not clogged with stones.

<Second Embodiment>
Next, the second embodiment will be described. The heat insulation method according to the second embodiment covers the outside of the spacecraft with a heat insulation sheet containing a material having heat insulation properties.
FIG. 29 is a schematic diagram illustrating a usage pattern of the heat insulating sheet according to the second embodiment. The spacecraft RV1 is folded and stored, and includes a heat insulating sheet TT that can be expanded from the folded state. As shown in FIG. 29, the heat insulating sheet TT is configured to cover the outside of the spacecraft RV1 when it is spread. With this configuration, sunlight is reflected by the heat insulating sheet and has a heat insulating property, so that the temperature change of the spacecraft can be reduced. The heat insulating sheet TT is preferably self-supporting.

The spacecraft RV1 may have a gas discharge mechanism that discharges gas into the heat insulation sheet TT and a controller that controls the gas discharge mechanism in a state where the heat insulation sheet TT is folded. Accordingly, the controller may control the gas discharge mechanism so as to discharge the gas into the heat insulating sheet TT in a state where the heat insulating sheet TT is folded. Thereby, since the heat insulation sheet swells with gas from the state in which the heat insulation sheet TT is folded, the outside of the spacecraft RV1 can be covered with the heat insulation sheet TT.

<Third Embodiment>
Next, a third embodiment will be described. The probe according to the third embodiment includes an interface connected to a payload or an accessory, and the interface converts a voltage to the payload or the accessory when the interface is connected to the payload or the accessory.

FIG. 32 is a functional block diagram of an interface according to the third embodiment. The interface IF includes a communication unit CU, a DC converter unit DCU, and a recording unit MU.
When the communication unit CU is connected to a payload or an accessory, the communication unit CU exchanges an electric signal with the payload or the accessory. For example, when the payload or accessory is the camera CR, a control signal for controlling the camera CR is transmitted to the camera CR via the communication unit CU. For example, when the payload or the accessory is the drill DR, a control signal for controlling the drill DR is transmitted to the drill DR via the communication unit CU.

When the DC converter unit DCU is connected to a payload or an accessory, the DC converter unit DCU converts the voltage of the power supply BT to the payload or the accessory and supplies power. For example, when the payload or accessory is a camera CR, the voltage of the power supply BT is converted into a voltage for the camera CR, and the converted voltage is supplied to the camera CR. For example, when the payload or accessory is the resource exploration sensor SS, the voltage of the power supply BT is converted into a voltage for the resource exploration sensor SS, and the converted voltage is supplied to the resource exploration sensor SS. For example, when the payload or accessory is a drill DR, the voltage of the power supply BT is converted into a voltage for the drill DR, and the converted voltage is supplied to the camera CR.

When the recording unit MU is connected to the payload or accessory, the recording unit MU records and / or transfers data acquired by the payload or accessory. For example, the recording unit MU transfers the sensor signal obtained by the resource exploration sensor SS to the processor PS. This sensor signal is transmitted from the communication unit CM to a lander or another probe. In addition, the recording unit MU transfers, for example, a video signal obtained by the camera CR to the processor PS. The video signal represents a still image or a moving image. This video signal is transmitted from the communication unit CM to a lander or another probe.

<Fourth Embodiment>
Next, a fourth embodiment will be described. A method of manufacturing a probe component according to the fourth embodiment is a process of manufacturing a probe component by a 3D printer arranged on a celestial body other than the earth (for example, a planet, a satellite, an asteroid, or a comet). Have The parts of the spacecraft include wheels, housings, antennas, solar panels, instruments, electrical harnesses, and the like. As a result, when a probe component fails or is damaged, the probe component can be manufactured on a celestial body other than the earth by a 3D printer, and the manufactured component can be replaced with the failed component.

FIG. 33 is a schematic diagram for explaining an example of the manufacturing method according to the fourth embodiment. As shown in FIG. 33, the 3D printer PR arranged on the moon surface manufactures wheels TY and solar panels SP. And the wheel TY and solar panel SP obtained by manufacture are attached to the lander L5. The installation may be performed manually by an astronaut on the moon, by an astronaut operating a robot arm, or by moving a robot arm of the robot. Good.

In addition, when a part of the spacecraft breaks down or is damaged, the spacecraft part (for example, the same spacecraft) is melted with the 3D printer using the melted material as a raw material. Such faulty or damaged parts). Thereby, when the parts of the spacecraft are out of order or broken, the spacecraft parts can be manufactured by reusing the spacecraft parts. In particular, when a 3D printer, for example, manufactures the same or failed part of the same spacecraft as a spacecraft part, the same part of the spacecraft can be manufactured by reusing the failed or damaged part. it can. In addition, you may manufacture the part of another spacecraft (for example, a spacecraft or a lander), not only the same part, but another part of a spacecraft.

According to the above, a probe manufacturing method for manufacturing a probe in a celestial body other than the earth uses a step of melting a failed or damaged probe part and a material after melting as a raw material, For example, manufacturing a probe component with a 3D printer on a planet, a satellite, an asteroid, or a comet, and attaching the manufactured probe component to the target probe. With this configuration, even if a probe component fails or is damaged, the probe can be regenerated by regenerating and replacing the probe component.
In addition, after installing the parts, resources (such as planets, satellites, asteroids, or comets) collected from non-Earth objects (such as natural resources such as minerals and rare metals) are loaded on the target lander. Lander takes off. Thereby, resources can be transported to the spacecraft in the earth, space station and outer space.

<Modification of Fourth Embodiment>

With this configuration, the parts of the spacecraft can be manufactured at a lower cost. Then, the manufactured probe parts are attached to the target probe. As a result, it is possible to manufacture the probe at a low cost, or to replace a damaged or broken probe component at a low cost.

<Fifth Embodiment>
Next, a fifth embodiment will be described. The spacecraft according to the fifth embodiment changes the inclination of the solar panel from the horizontal plane according to the position of the sun. Thereby, the electric power generation amount of a solar panel can be increased.

The drive mechanism DM is controlled. Thereby, the inclination based on the horizontal plane of the solar panel SP1 can be changed according to the irradiation angle of sunlight, and the amount of light hitting the solar panel SP1 can be increased. The amount can be increased.

In addition, although the position of solar panel SP1 was provided in the side surface of housing | casing HS2, not only this but an upper surface or a lower surface may be sufficient. In addition, when the solar panel SP1 has flexibility, the solar panel SP1 may be wound like a carpet, and the wound solar panel SP1 may be expanded when it is desired to generate power.

<Sixth Embodiment>
Next, a sixth embodiment will be described.

The controller CON determines the direction and / or angle of the reflector RL2 so that the reflected light is irradiated to another probe R12 according to the position of the sun relative to the own aircraft and the position of the other probe R12. May be changed. Thereby, even if the position of the sun and the position of another spacecraft R12 change, the reflected light is irradiated to the spacecraft R12, so that the solar panel of another spacecraft R12 can continue to generate electricity. And the search can be continued using the generated power.

Similarly, the lander L11 includes a controller CON. The controller CON changes the orientation and / or angle of the reflector RL1 so that the reflected light is irradiated to the spacecraft R12 according to the position of the sun relative to the spacecraft and the position of the spacecraft R12. You may do it. Thereby, even if the position of the sun and the position of the spacecraft R12 change, the reflected light is irradiated to the spacecraft R12, so that the solar panel of the spacecraft R12 can continue the power generation, and the generated power The exploration can be continued using.

As described above, the exploration system S5 according to the sixth embodiment includes the reflectors RL1 and RL2 and the explorer R12 having a solar panel. When the spacecraft R12 is in a place where it is not exposed to the sunlight, the sunlight is reflected by the reflector RL1 provided in the lander L11 and / or the reflector RL2 provided in the explorer R11. The spacecraft R12 is irradiated with solar light and is generated by the solar panel of the spacecraft R12.

Next, a seventh embodiment will be described. In the seventh embodiment, the spacecraft emits a camera to a place where it is difficult for the spacecraft to enter (in this case, a vertical hole). Get the captured image.

FIG. 36 is a schematic diagram showing a schematic configuration of the exploration system according to the seventh embodiment. As shown in FIG. 36, the exploration system S8 includes a probe R41 arranged on the moon surface. The probe R41 includes a probe main body B41, a wiring WR, a camera CR connected to the probe main body B41 via the wiring WR, and an injection mechanism IJ for injecting the camera CR. FIG. 36 shows a state in which the camera CR is ejected by the ejection mechanism IJ and landed after the ejection. In this state, the camera CR captures an image and transmits an image obtained by the capture to the probe R41 via the wiring WR.

As described above, the probe R41 according to the seventh embodiment includes the camera CR, the injection mechanism IJ that can inject the camera CR, and the controller CON that controls the camera CR and the injection mechanism IJ. The controller CON controls the camera CR to take a picture at a point where the camera CR has landed after injection, and acquires an image obtained by the photography from the camera. As a result, an image at a location where it is difficult for the spacecraft to enter the camera CR is obtained, and thus a location where the spacecraft R41 is difficult to enter (here, a vertical hole) can be observed.

In addition, the exploration method according to the seventh embodiment includes a step of ejecting the camera CR from the probe R41 having the ejection mechanism IJ, a step of photographing at the point where the camera CR has landed after the ejection, and the camera CR And a step of transmitting the image obtained by the above to the probe R41 via the wiring WR. As a result, an image at a location where it is difficult for the spacecraft to enter the camera CR is obtained, and thus a location where the spacecraft R41 is difficult to enter (here, a vertical hole) can be observed.

The take-up mechanism may take up the wiring WR so that the camera CR can be stored in the injection mechanism IJ in an injectable manner. Thereby, it can inject | emitted many times and can image | photograph in a different place.

Further, the camera CR and the probe main body B41 may each have a wireless communication function, and in that case, an image may be wirelessly transmitted from the camera CR to the probe main body B41.

<Eighth Embodiment>
Next, an eighth embodiment will be described. The spacecraft according to the eighth embodiment measures a case, a switching mechanism that switches between an open state that releases heat in the case and a blocking state that blocks heat in the case, and a temperature outside the case. And a processor, and the processor controls the switching mechanism to switch between the open state and the shut-off state according to the temperature measured by the temperature sensor. With this configuration, when the temperature outside the housing rises, it is switched to the shut-off state, suppressing the inflow of heat into the housing, and when the temperature outside the housing is lowered, it is opened. By switching and discharging the heat to the inside of the housing, a change in the temperature inside the housing can be suppressed.

FIG. 37 is a schematic diagram showing a schematic configuration of the spacecraft according to the eighth embodiment. As shown in FIG. 37, the probe RV5 includes a housing HS5, a processor PS, a temperature sensor TS, and a switching mechanism SW.
The temperature sensor TS measures the temperature outside the housing HS5.
The switching mechanism SW switches between an open state in which the heat in the housing HS5 is released and a blocking state in which the heat in the housing HS5 is cut off.
The processor PS controls the switching mechanism SW so as to switch between the open state and the shut-off state according to the temperature measured by the temperature sensor TS.

FIG. 38A is a schematic perspective view illustrating an example of the switching mechanism SW in the cutoff state. FIG. 38B is a schematic perspective view illustrating an example of the switching mechanism SW in the open state.
As shown in FIG. 38A, the switching mechanism SW includes a first frame HM, a second frame IM stacked on the first frame, a shutter frame SF provided on the second frame IM, and a shutter frame. The shutter SH is slidable in the longitudinal direction with respect to the SF.

A plurality of rectangular first through holes are formed in the shutter SH at intervals. Similarly, in the shutter frame SF, a plurality of rectangular second through holes are formed at intervals. The second through hole is, for example, approximately the same size as the first through hole.

When the switching mechanism SW is in the shut-off state, as shown in FIG. 38A, the shutter frame SF has a main body portion (the second through hole is not opened) below the first through hole of the shutter SH. Part) is arranged. Thereby, when the sun hits the spacecraft RV5, heat from the outside is blocked by the main body portion of the shutter frame SF, so that a heat insulating effect can be obtained, and a temperature rise inside the housing HS5 can be suppressed. Here, the shutter frame SF is preferably made of a highly heat-insulating material. Thereby, when the switching mechanism SW is in the cut-off state, the heat insulation effect can be improved. Also, as shown by the arrows in FIG. 38A, the internal gas is blocked by the back surface of the main body portion of the shutter SH (the portion where the first through hole is not opened) and does not escape to the outside.

On the other hand, when the switching mechanism SW is in the open state, as shown in FIG. 38B, in the shutter frame SF, the second through hole of the shutter frame SF is disposed below the first through hole of the shutter SH. Thereby, the heat inside the housing HS5 is discharged to the outside of the housing HS5 through the first through hole of the shutter SH and the second through hole of the shutter frame SF.

For example, when the temperature outside the housing HS5 rises, the processor PS may control to switch to the shut-off state as shown in FIG. 38A. Thereby, inflow of the heat | fever to the inside of housing | casing HS5 can be suppressed. On the other hand, when the temperature outside the housing HS5 decreases, the processor PS may control to switch to the open state as shown in FIG. 38B. Thereby, the heat inside the housing HS5 can be discharged as shown by the arrow in FIG. 38B. In this way, the shutter SH is closed when it is hot such as when the sun hits it, and the shutter SH is opened when it is cold such as when the sun does not hit it, so that a change in the temperature inside the housing HS5 can be suppressed. .

Note that the temperature sensor TS may measure the temperature inside the housing HS5. Accordingly, the processor PS can control the switching mechanism SW so as to switch between the open state and the shut-off state according to the temperature inside the housing HS5.

Further, the processor PS may control the switching mechanism SW so as to switch between an open state and a shut-off state according to a preset month cycle. For example, the processor PS may control the switching mechanism SW so as to switch to the cut-off state during a period when sunlight falls on the moon, and may control the switching mechanism SW so as to switch to an open state when the moon does not receive sunlight. Good.

Thus, as shown in FIG. 39B, the two pairs of legs LG1, LG2 are rotated to the vicinity of the lower surface of the housing HS to open the angle between the two pairs of legs LG1, LG2. LG1 and LG2 can be folded. The legs LG1 and LG2 may be made of, for example, flexible carbon fiber reinforced plastic (Carbon Fiber Reinforced Plastic: CFRP).
