Description

The utility model relates to research small-sized binary spacecraft (SBV), weighing less than 1000 grams, designed to search and collect nanosized cryo-temperature objects of extraterrestrial origin in outer space, clusters of which are located in the vicinity of libration points (Lagrange points) in the form of dust cloud-like structures, in whose composition included cryotemperature nanoobjects. For example, near the systems formed by Saturn and its satellites, Jupiter and its satellites, as well as other astronomical systems located closer to the outskirts of the solar system. Cryotemperature nano-objects of extraterrestrial origin collected by BKA and delivered to the Earth, which include frozen aqueous or other compositions of solutions that have a liquid phase of the state and passed into a solid state at cryogenic temperatures during the formation of their structures, are subjected to biological and physicochemical analysis under Earth conditions. When the unique properties of the assembled low-temperature nano-objects are revealed, an artificial synthesis of nano-objects similar to those assembled in space is carried out, which have new properties that are not found on Earth.

Used in the description of the utility model, the phrase "binary spacecraft" (BSC) is understood as a spacecraft consisting of two bodies and a common reinforced flexible tape solar battery located between them, deployed by unwinding the solar battery, wound into a roll, with the reverse movement of one body relative to the other in opposite directions and back, carried out using multi-vector matrix rocket engines (MMRD). A flexible strip solar battery (SB) is a flexible dielectric strip substrate on which an array of interconnected thin-film solar photocells is deposited in combination with microcontainers for collecting nano-objects. Libration points L1-L5 are points where the gravitational and centrifugal accelerations acting on a body placed in the vicinity of the point are balanced, due to which the so-called "small bodies" can accumulate there, for example, in the vicinity of points L4, L5 (Patent for invention RU 2691686 C1, 06/17/2019, G01N 1/02, B64G 4/00, Method for collecting and delivering space dust samples to Earth from the vicinity of libration points of the Earth-Moon system and a set of tools for its implementation / Tsygankov O.S.).

Cryotemperature nanoobjects - individual nanoparticles cooled below 120 Kelvin (K) with a size in the range of 2-100 nanometers and systems of nanoparticles that form homogeneous or inhomogeneous multi-link structures, the dimensions of which are less than 2000 nanometers. Depending on the size and material from which nano-objects were formed, they may have the properties of responding to magnetic or electric fields, converting the wavelengths of electromagnetic radiation (Patent for invention RU 2723899 C1, 06/18/2020, G01Q 60/24, B82Y 35/00, Scanning probe of an atomic force microscope with detachable remote-controlled nanocomposite radiating element doped with quantum dots, upconverting and magnetic nanoparticles of the core-shell structure / Linkov V.A., Gusev S.I., Vishnyakov N.V., Linkov Yu.V., Linkov P.V.).

A binary spacecraft is known for searching and collecting extraterrestrial objects with the properties of quantum dots and upconvertible nanoparticles in the vicinity of libration points, containing two panel-shaped bodies connected to containers, a flexible substrate with thin-film solar photocells, which is made in the form of a dielectric tape with the possibility of rolling into a roll, with applied information, power, high-voltage buses, a collinear antenna, a positional barcode tape, microcontainers, each of which contains film electrodes and rigid dielectric microsubstrates, also contains two multi-vector matrix rocket engines, two retractable telescopic rods, two linear stepper motors, six reversible stepper motors, four coils for placing a flexible dielectric tape substrate and a sealing film, a thermocouple for sealing microcontainers with assembled nano-objects, two laser rangefinders, two CCD arrays, two solar sensors, a barcode sensor, two disk current collectors, two controllers, two voltage stabilizers, high-voltage transceiver power supply (Patent for invention RU 2749431 C1, 06/10/2021, B64G 1/22, Binary spacecraft for searching and collecting extraterrestrial objects with the properties of quantum dots and upconverting nanoparticles in the vicinity of Libration Points / Linkov V.A.).

The disadvantage of the device is the inability to search and collect cryo-temperature extraterrestrial nano-objects with different physical properties, collected separately using an electric field, followed by conveyor sealing and storage of the collected cryo-temperature nano-objects in a cryo-temperature environment, when scanning the vicinity of the libration points of the planets included in the solar system.

The closest in technical essence is a binary spacecraft for searching and collecting extraterrestrial nano-objects in the vicinity of the libration points of the planets in the solar system, containing two cylindrical bodies, a flexible substrate with thin-film solar photocells, which is made in the form of a dielectric tape with the possibility of rolling into a roll, with applied information, power, high-voltage buses, collinear antenna, positional barcode tape, microcontainers, film electrodes, flat electromagnetic coils, rigid dielectric microsubstrates, also contains four multi-vector matrix rocket engines with undulating cylindrical surfaces, four retractable telescopic rods, four linear stepping motors , cylindrical thermocouple, sealing film, solar sensor, barcode sensor, two controllers, two voltage regulators, high-voltage power supply, transceiver, four disk-shaped scanning laser rangefinders, navigation star camera, four flat stepper motors, two pressure linear stepper motors, U-shaped rod, retractable U-shaped rod, hot-melt adhesive microgranules applied to the edges of microcontainers (Patent for the invention RU 2761486 C1, 08.12.2021, B64G 1/22, Binary spacecraft FOR searching and collecting extraterrestrial nano-objects in the vicinity of the libration points of the planets included in Solar system / Linkov V.A.).

The disadvantage of the device is the inability to search and collect cryo-temperature extraterrestrial nano-objects with different physical properties, collected separately using an electric field, followed by conveyor sealing and storage of the collected cryo-temperature nano-objects in a cryo-temperature environment, when scanning the vicinity of the libration points of the planets included in the solar system.

The introduction of disk solar sensors placed on a U-shaped rod and installed perpendicular to each other by flat surfaces made it possible to orient the solar arrays simultaneously with the deployment or collapse of the USC. The introduction of the control bus for thin-film thermoelectric cooling modules made it possible to connect on and off signals from controllers to thin-film thermoelectric cooling modules. The introduction of hot-melt adhesive microgranules, in which superparamagnetic nanoparticles are used as heating elements, capable of heating under the action of a high-frequency (HF) electromagnetic field tuned into resonance, made it possible to heat the adhesive composition of hot-melt adhesive microgranules from the inside, without heating neighboring elements. The introduction of an RF generator with programmable frequency tuning from a change in the control binary code indicated on a positional tape with a two-dimensional barcode made it possible to heat only superparamagnetic nanoparticles tuned in resonance with the frequency of induction heating, introduced in different concentrations into certain microgranules of hot-melt adhesive, and at the same time prevent heating microgranules with other parametric characteristics (ratios of core and shell sizes of magnetic nanoparticles, their chemical composition and concentration of components in a microgranule) heated at other resonant frequencies. The introduction of a flat inductor connected to an RF generator with a programmable frequency made it possible to carry out local selective sealing of microcontainers through a screen-vacuum heat-insulating coating without heating adjacent sections. The introduction of a pressure roller made it possible, due to pressure, to tightly connect the molten microgranules of hot-melt adhesive doped with superparamagnetic nanoparticles located on the edges of the walls of the microcontainers with the surface of a transparent sealing film. The introduction of cooling film thermoelectric modules connected to the inner sides of the microsubstrates made it possible to exclude the thawing of low-temperature nano-objects at the moment of sealing the microcontainers with the assembled low-temperature nano-objects. The introduction of tape thin-film heat sinks deposited on the shady side of a flexible substrate made it possible to remove heat directly into space. The introduction of the control bus for turning on thermoelectric modules made it possible to turn thermoelectric modules on and off at the moment of welding (sealing). Maintaining a screen-vacuum heat-insulating layer deposited on a flexible dielectric tape substrate made it possible to isolate the microcontainers deposited on it with low-temperature nano-objects from the thermal effect of the Sun. The introduction of individual two-dimensional barcodes indicating the resonant frequency of the induction heating of each group of hot-melt adhesive microgranules made it possible to accurately position the boundaries of the dimensions of spot-welded microcontainers through screen-vacuum thermal insulation rolled up without melting the surfaces of previously sealed microcontainers located in previous previously wound layers, as well as with to extract rigid dielectric microsubstrates with collected extraterrestrial material by minimal heating when unwinding a roll in laboratory conditions on Earth.

The technical result is the possibility of searching and collecting cryotemperature extraterrestrial nano-objects with different physical properties, collected separately using an electric field, followed by conveyor sealing and storage of the collected cryo-temperature nano-objects in a cryo-temperature environment, when scanning the vicinity of the libration points of the planets included in the solar system.

A binary spacecraft for searching and collecting extraterrestrial cryo-temperature nano-objects in the vicinity of the libration points of planets in the solar system contains (Fig. 1, 2) the first 1 and second 2 cylindrical bodies, the first 3, the second 4, the third 5, the fourth 6 MMRD with wavy cylindrical surfaces, first 7, second 8, third 9, fourth 10 linear stepper motors (Fig. 3), first 11, second 12, third 13, fourth 14 retractable telescopic rods, first 15, second 16, third 17, fourth 18 disc-shaped scanning laser rangefinders, first 19, second 20, third 21, fourth 22 flat stepper motors, first 23 and second 24 pressure linear stepper motors, pressure roller 25, flat inductor 26, high-frequency generator with a programmable frequency 27, retractable U-shaped two-axis rod 28, a transparent sealing film 29 (Fig. 2), a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, thin-film solar photocells 31, a power bus 32, a common information bus 33, a control bus for thin-film thermoelectric cooling modules 34, a high-voltage bus with positive polarity 35, a high-voltage bus with negative polarity 36, film electrodes 37 (Fig. 4), rigid dielectric microsubstrates 38, thin-film thermoelectric cooling modules 39 (Fig. 7), thin-film tape heat sinks 40, microcontainers 41, a positional tape with a two-dimensional barcode 42, a two-dimensional barcode sensor 43, the first 44, the second 45 disk solar sensors, navigation star chamber 46, U-shaped rod 47, first 48 and second 49 controllers, first 50 and second 51 voltage stabilizers, high-voltage power supply 52, collinear antenna 53, transceiver 54, hot-melt adhesive microgranules doped with groups of superparamagnetic nanoparticles 55 ranked by parameters (Fig. .6). In FIG. 3, within the boundaries of the closed dotted lines, there are elements structurally placed in the first 1 and second 2 cylindrical housings; λ1, λ2, λ3, λ4 - selected wavelengths of electromagnetic radiation of the optical range emitted by the first 15, second 16, third 17, fourth 18 disc-shaped scanned laser range finders, 56 - cryo-temperature nano-objects attracted to the surfaces of rigid dielectric microsubstrates.

On the sunny side of the flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, thin-film solar cells 31 are arranged in an orderly manner, constantly oriented to the Sun. On the surface between the solar cells 31, from the shadow opposite side of the flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, microcontainers 41 are applied in the direction of the trajectory of the BKA movement, in which elements are placed to create electric fields that attract cryotemperature nano-objects drifting in gravitationally balanced zones 56 and storing the collected cryo-temperature nano-objects 56.

To preserve the structure of the assembled cryotemperature nanoobjects 56 attracted to the outer surface of the rigid dielectric microsubstrate 38, several functional layers are deposited on its surface (Fig. 7) in the following sequence: thermoelectric cooling modules 39, a thin-film tape heat sink 40 connected to the screen-vacuum heat-insulating layer of a flexible dielectric tape substrate 30, with a transparent sealing film 29 stretched over the thin-film elements located on the side facing the Sun. Each layer or their combination performs certain functions . Rigid dielectric microsubstrate 38 is used to accumulate cryotemperature nanoobjects 56, its size is adapted to the type of microscope that performs subsequent studies in Earth conditions, which eliminates the deformation of nanoobjects and does not require additional movement of the collected cryotemperature nanoobjects 56 from one microsubstrate to another.

Depending on the location of the film electrodes 37 in the upper or lower part of the flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, they are connected to high-voltage buses 35 and 36 with positive and negative polarity. When the high-voltage power source 52 is turned on, an electric field is created that attracts oppositely charged cryo-temperature nano-objects 56 to the film electrodes 37, which are deposited on rigid dielectric microsubstrates 38. Micro-containers 41 store cryo-temperature nano-objects 56 sorted into two classes with non-magnetic properties, negatively and positively charged cryotemperature nanoobjects 56.

To exclude the ingress of terrestrial nanoparticles, planar microcontainers 41 are sealed from above with a transparent sealing film 29, in the initial position placed on the side of solar cells 31, and layer by layer, together with a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, is wound on the second cylindrical body 2.

Cryotemperature nanoobjects 56 in the pores of which water can be in a solid state are attracted by an electric field and deposited on the outer surfaces of rigid dielectric microsubstrates 38. To prevent changes in the structures (melting) of the assembled cryotemperature nanoobjects 56 at the time of sealing microcontainers 41, thermoelectric cooling of rigid dielectric microsubstrates 38 is used. the side of rigid dielectric microsubstrates 38 is connected to the cooling (cold) sides of thin-film thermoelectric modules 39 assembled from deposited thermoelectric elements (Peltier elements) into matrices of pairs of n-type and p-type semiconductor materials. The heat flux released on the warm side of thin-film thermoelectric cooling modules 39 is removed by thin-film tape heat sinks 40 located on the shadow side (outer space temperature in the shadow is about 4 K) of a flexible dielectric substrate with a screen-vacuum heat-insulating layer 30 and is radiated (discharged) into space .

To link the heating frequency of hot-melt adhesive microgranules to the identification number of the sealed microcontainer, a set of groups of superparamagnetic particles with different resonant heating frequencies (hot-melt adhesive microgranules doped with parameters-ranged groups of superparamagnetic nanoparticles 55) is used. To do this, microgranules doped with superparamagnetic nanoparticles with individual programmable characteristics depending on the number of the microcontainer, differing from each other in parameters (ratios of core sizes and shell thickness of nanoparticles, their geometric shape, chemical composition and concentration of components) to organize induction heating of certain groups of microgranules by strictly defined resonant frequencies without heating the assembled cryotemperature nanoobjects.

To implement the utility model, for example, known technologies for manufacturing components can be used. As a multi-vector matrix rocket engine (MMRM) with a wavy cylindrical surface, a multi-vector matrix rocket propulsion system with digital control of the magnitude and direction of thrust can be used, which consists of a flat disc-shaped monolithic heat-resistant dielectric substrate with a wavy outer contour with a square matrix reverse structure placed on it. motor cells, connected to a cylindrical cavity repeating its contour with a wavy profile, a monolithic heat-resistant dielectric substrate with a radial-fan orientation of all longitudinal axes of cone-shaped micropores to the centers of alternating conjugated concave and convex semicircles, which together form a closed undulating outer surface. All cone-shaped micropores are filled with solid fuel and ranged by volume in proportions of successive powers of two (1-2-4-8-16-32), which ensure the generation of a multitude of multidirectional thrust vectors with precise digital control of the thrust value of each cell in binary code (Patent for invention RU 2707474 C1, 11/26/2019, F02K 9/95, B64G 1/40, Multivector matrix rocket propulsion system with digital control of the magnitude and direction of thrust of propulsion cells for small spacecraft / Linkov V.A., Gusev S.I., Kolesnikov S.V., Linkov Yu.V., Linkov P.V., Taganov A.I.).

In the manufacture of solar panels, known technologies for the manufacture of flexible solar thin-film batteries can be used, made on the basis of a flexible substrate with deposited thin-film photovoltaic cells made of at least amorphous silicon (a-Si), cadmium telluride (CdTe), gallium arsenide (GaAs ) (Patent US 9758260 B2, Sep.12, 2017, B64G 1/22, B64G 1/10, LOW VOLUME MICRO SATELLITE WITH ELEXIBLE WINDED PANELS EXPANDABLE AFTER LAUNCH).

Thin-film thermoelectric cooling modules 39 can be made, for example, according to the well-known design of a thin-film thermoelectric device with balanced electrical parameters of p- and n-semiconductor branches (Patent for invention RU 2587435 C2, 06/20/2016, G05D 23/30, H05K 7/20, Thin-film thermoelectric device with balanced electrophysical parameters of p- and n-semiconductor branches / Islaimov T.A., Gadzhiev Kh.M. et al.).

Thin-film tape heat sinks 40 can be implemented on the basis of diamond heat sinks (the thermal conductivity of diamond heat sinks, depending on the technology of their manufacture, is 2-5 times higher than this parameter for copper), for example, using the well-known technology for manufacturing polycrystalline diamond films containing nanodiamond powders (Patent for invention RU 2750234 C1, 06/24/2021, S01V 32/15, V82V 3/00, Method for obtaining polycrystalline diamond films /Polushin N.I., Maslov A.L., Laptev A.I.).

As a screen-vacuum thermal insulation layer, for example, multilayer film thermal insulation used in space technologies and consisting of alternating layers of a non-flat polymer film with metal sputtering and a polymer mesh can be used (Patent for invention RU 258740 C2, 06/20/2016, B64G 1/58 , SCREEN-VACUUM thermal insulation of a spacecraft / Aristov V.F.) or with alternating layers of microstructured elements (Patent for invention RU 2555891 C1, 07/10/2015, B64G 1/58, V81V 7/04, Microstructural multilayer screen-vacuum insulation of space devices / Anurov A.E., Zhukov A.A.), or, for example, made of a material for thermal protection of space or cryogenic equipment consisting of alternating layers of heat-reflecting perforated film and a separation pad (Patent for invention RU 266884 C1, 12.09.2018, B64G 1/58, Material for screen-vacuum thermal insulation and method of its manufacture / Alekseev S.V., Belokrylova V.V. and others).

For local heating of the polymer from inside the hot melt adhesive microgranules 55, well-known superparamagnetic nanoparticles immersed in it, used, for example, for local heating of tissues in medicine, can be used. Doping additives impart magnetic properties to the dielectric granules of hot-melt adhesive during their mixing, which are necessary for remote heating of superparamagnetic nanoparticles by a high-frequency electromagnetic field and preventing their sticking after its removal. For the implementation of the invention, for example, known technologies for the manufacture of magnetic nanoparticles of the core-shell structure (Patent Application Publication Pub. No.: US 20130195767 A1 Pub. Date: Aug. 1, 2013, MAGNETIC NANOPARTICLES), (Patent Application Publication Pub. No.: US 20140225024 A1 Pub. Date: Aug. 14, 2014 CORE_SHELL STRUCTURED NANOP ARTICLE HAVING HARD-SOFT, MAGNETIC HETEROSTRUCTURE, MAGNET PREPARED WITH SAID NANOPARTICLE, AND PREPARING METHOD THEREOF), (Patent Application Publication Pub. No.: US 201303 42297 A1 Pub. Date: Dec. 26, 2013 MAGNETIC EXCHANGE COUPLED CORE-SHELL NANOMAGNETS). The ferromagnetic core of the core-shell magnetic nanoparticle may, for example, include at least one material selected from the group consisting of Fe, Co, Ni, FeOFe ₂ O ₃ , NiOFe ₂ O ₃ , CuOFe ₂ O ₃ , MgOFe ₂ O ₃ , MnBi, MnSb, MnOFe ₂ O ₃ , CrO ₂ , MnAs, SmCo, FePt or combinations thereof, but not limited to. The outer shell (surrounding the magnetic core) of the magnetic nanoparticles of the core-shell structure is formed from a magnetically soft or superparamagnetic material, (to prevent sticking of nanoparticles), for example, may include at least one material selected from the groups consisting of Fe ₃ O ₄ , FeO , CoFe ₂ O ₄ , MnFe ₂ O ₄ , NiFe ₂ O ₄ . ZnMnFe ₂ O ₄ , or combinations thereof, but not limited to.

The device works as follows: after delivery of the BKA to the libration point, the first 7, second 8, third 9, fourth 10 linear stepper motors are switched on, extending the first 11, second 12, third 13, fourth 14 telescopic rods, retracting the first 3, second 4, third 5, fourth 6 MMRD with a wavy cylindrical surface from the ends of the first 1 and second 2 cylindrical bodies. The first 23 and second 24 clamping linear stepper motors retract the retractable U-shaped two-axis rod 28 with the clamping roller 25 fixed on it and the flat inductor 26 from the cylindrical body 2. At the same time, the first 15, the second 16, the third 17, the fourth 18 disk-shaped scanning laser rangefinders are turned on. operating at dedicated wavelengths λ1, λ2, λ3, λ4 to eliminate the influence of interference from active or passive sources. After checking the performance of the first 15, second 16, third 17, fourth 18 disk-shaped scanning laser rangefinders, the first 3, second 4, third 5, fourth 6 MMRD with wavy cylindrical surfaces are switched on, which create rotation of the first 1 and second 2 cylindrical bodies, unwinding the rolled into a roll of a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30 and a transparent sealing film 29 located parallel, at a minimum distance with its surface, while removing the first 1 cylindrical body from the second 2 cylindrical body, stretching the canvas of the transparent sealing film 29 adjacent to it flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, in opposite directions, to prevent sagging. After deploying a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30 to the required length, with thin-film solar cells 31 located on its (solar) surface, the BKA switches to the mode of orientation and tracking the Sun. Rotation of the sunny side of the flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30 in the direction of the Sun and its simultaneous optimal tension is carried out using the first 3, second 4, third 5, fourth 6 MMRD with wavy cylindrical surfaces, carrying out convergence or removal, or changing the angle inclination, respectively, of the first 1 or second 2 cylindrical bodies. With the help of the navigation star camera 46, the starting point of scanning is determined and the scanning trajectory of the investigated neighborhood of the libration point is corrected. According to the code of the coordinates of the Sun received from the first 44 and second 45 disk solar sensors, and information coming from the first 15, third 17 and second 16, fourth 18 disk-shaped scanning laser rangefinders about the distance and angles of the axes between the first 1 and second 2 cylindrical housings, synchronous angular rotations of the first 1 and second 2 cylindrical bodies are carried out, without changing the distance between them. The rotation of the navigation star camera 46, fixed on the U-shaped rod 47 and connected at both ends with the first 19 and second 20 flat stepper motors, is carried out by their synchronous rotation at a given angle in the navigation mode. On a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, in addition to thin-film solar cells 31 and power buses 32 connecting them, a collinear antenna 53 and a wired bidirectional communication channel in the form of an information bus 33 are also applied to exchange information between the first 48 and second 49 controllers .

For retraction from dust cloud-like structures, cryotemperature nano-objects 56, on a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, high-voltage buses 35 and 36 are placed, connected to film electrodes 37 (Fig. 4), deposited on the outside on rigid dielectric microsubstrates 38 , on which oppositely charged cryotemperature nano-objects 56 are deposited (accumulated at the bottom of microcontainers 41). The electric current generated by thin-film solar cells 31 is also fed to the inputs of the first 50 and second 51 voltage stabilizers, which provide stabilized voltages for powering the high-voltage power source 52 and the transceiver 54 connected to the collinear antenna 53, as well as the voltage for charging the batteries of the first 48 and the second 49 controllers and provide power to all sensors and motors. The high-voltage voltage from the high-voltage power source 52 is supplied to high-voltage buses with positive 35 and negative 36 polarity, located on the shadow side of the flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30 to create attracting electric fields at the bottom of microcontainers 41.

As the dust cloud-like structures are scanned, microcontainers 41 are sequentially sealed. In the initial state, transparent sealing film 29 is located on the side of thin-film solar cells 31 and does not prevent the passage of light and the drawing in of cryotemperature nanoobjects 56 into microcontainers 41 located on the opposite side of the flexible dielectric tape substrate with a screen - vacuum heat-insulating layer 30. When rolled up after the first turn (coil), the surface of the transparent sealing film 29 begins to adhere tightly to the surface of microcontainers 41 with applied microgranules of hot-melt adhesive doped with superparamagnetic nanoparticles 55. Sealing of the assembled cryotemperature nano-objects 56 occurs as follows. The flat inductor 26, combined with the pressure roller 25 using the first 23 and 24 second pressure linear stepper motors operating synchronously, is pressed (in the place of the two-dimensional barcode) parallel to the second cylindrical body 2, then the second 49 controller issues a binary code read by the two-dimensional barcode sensor 43 from a positional tape with a two-dimensional barcode 42, which determines for this microcontainer 41 the frequency of operation of a high-frequency generator with a programmable frequency 27 connected to a flat inductor 26, which through a flexible dielectric tape substrate with a screen-vacuum thermal insulation layer 30 and a transparent sealing film 29 (the melting point of which is higher melting temperature of the hot melt adhesive microgranules doped with superparamagnetic nanoparticles 55) heats the superparamagnetic nanoparticles introduced into the hot melt adhesive microgranules 55, which melt the (adhesive) material around them deposited on the upper parts (edges) of the side walls of the microcontainers 41. (Fig. 6). As a result of induction heating, microgranules of hot-melt adhesive doped with superparamagnetic nanoparticles 55 melt, acquiring adhesive properties, glue the surface of microcontainers 41 with the surface of a transparent sealing film 29. At the same time, the third 21 and fourth 22 flat stepping motors rotate the pressure roller 25 around the axis of the second cylindrical body 2 at a certain angle and for a certain time interval, determined by the program of the second controller 49 and read from the positional tape of the two-dimensional barcode 42, the two-dimensional barcode sensor 43 for sealing the line of microcontainers 41. flat stepper motors move the retractable U-shaped two-axis rod 28 to the initial angular position, and the first 23 and second 24 clamping linear stepper motors divert the retractable U-shaped two-axis rod 28 with the inductor 26 fixed on it and the pressure roller 25 from the second 2 cylindrical housing for winding a flexible dielectric tape substrate with a screen-vacuum heat-insulating layer 30, and starting the next sealing cycle of the next microcontainers 41.

In the background of Fig. Figure 9 schematically shows the Sun, to which the LKA solar cells are oriented, and Saturn with its largest satellites (the existence of 82 satellites of Saturn was confirmed at the beginning of 2022), which together form a system with a large number of libration points, in the vicinity of which cryotemperature nano-objects with new properties are searched for .

The proposed design of a binary spacecraft for searching and collecting extraterrestrial cryo-temperature nano-objects in the vicinity of the libration points of the planets in the solar system makes it possible to: deploy and collapse a large-area search flexible tape SB between two shunting MMRDs stretching it with a wavy cylindrical surface (a large area of solar batteries required on the outskirts of the solar system away from the sun). To carry out a separate collection of cryo-temperature nano-objects with non-magnetic properties that have fallen into the zone of attraction of electric fields. To implement conveyor sealing of cryotemperature nanoobjects assembled on rigid dielectric microsubstrates, divided by classes and placed in appropriate microcontainers, in combination with folding into a compact, transportable roll of a flexible tape web, which could not previously be done using known designs of small-sized spacecraft.
