A suspending release device for observing a drop vibration attitude change of a lander and a test method are provided. The device includes a bench system, a lifting system fixed to the bench system, a horizontal frame system, an attitude control system, and a suspending release system hinged to the attitude control system. The horizontal frame system may slide vertically on the bench system and may drive the attitude control system to slide horizontally. A test lander is fixed to a release sliding block. The release sliding block is locked with a main load bearing block. An attitude of the test lander when releasing is adjusted. The horizontal frame system is lifted to a predetermined height. Guide rods are indirectly driven to release the sliding block by a motor. The whole lander falls freely and touches the ground to collide, and the process is recorded by a high-speed camera.

A satellite constellation forming system (600) forms a satellite constellation having a plurality of orbital planes in each of which a plurality of satellites fly at the same average orbital altitude. A satellite constellation forming unit (11) forms a passage region for a space object to pass through before the space object passes through an orbital altitude of the satellite constellation from above the satellite constellation. After the space object has passed through the passage region, the satellite constellation forming unit (11) restores the satellite constellation to a state before the passage region is formed.

A satellite constellation forming system (600) forms a satellite constellation which is composed of a satellite group that cooperatively provides a communication service, and has a plurality of orbital planes in each of which a plurality of satellites fly at the same orbital altitude. Each satellite of the satellite group includes inter-satellite communication means and satellite-ground communication means. A satellite constellation forming unit (11) forms the satellite constellation which has ten or more orbital planes with different normal directions, and in which at least one relative angle in an azimuth direction of adjacent orbital planes of the plurality of orbital planes is arranged to be uneven and satellite-ground communication means of satellites flying in orbital planes spaced unevenly have a communication range that achieves complete ground coverage above the equator.

An object is to appropriately manage disclosure of information on the orbit of a satellite constellation. An information management device (1000) is installed in at least one of a plurality of management business devices each of which conducts a management business for a plurality of space objects flying in space. A storage unit (1400) stores orbit forecast information (51) including an orbit forecast, which is a forecast value of an orbit of each of the plurality of space objects, and a forecast error that is forecast for the orbit. An information disclosure unit (1100) determines whether the orbit forecast information (51) is to be disclosed to a different information management device, based on a disclosure threshold (141) for determining whether the orbit forecast information (51) is to be disclosed and the forecast error.

A cooling device (100) is a device that cools a heat generator such as an electronic device (2) mounted in a mounting device such as an artificial satellite. The cooling device (100) includes a refrigerant flow path (10) configured annularly by sequentially connecting a pump (3) that circulates a liquid refrigerant, a cooler (4) that cools a heat generator such as an electronic device (2) with the refrigerant, and a heat exchanger (5) that cools the refrigerant. In addition, the cooling device (100) has a vapor mixing unit (20) that mixes the vapor generated by heat of at least one of heat intrusion from an outside to a mounting device such as an artificial satellite and heat generation of a heat generator such as the electronic device (2) into the refrigerant flowing into a cooler (4) in the refrigerant flow path (10).

An interplanetary transportation system that includes a tunnel that spans between different planetary bodies and uses an electromagnetic propulsion system for propelling space-faring vehicles. The tunnel can be fixed and powered by outer space energy resources, such as the sunlight. The tunnels include fixed spaced rings and a mobile ring. The vehicle can be mounted to the mobile ring, wherein the spaced rings and the mobile ring propels the vehicle using motional EMF.

A workflow deployment system comprising at least one computing device having a memory unit and a first communication unit, and a plurality of software agents, wherein each software agent is installable on an electronic apparatus of the plurality of electronic apparatuses, wherein each software agent exchanges data with the electronic apparatus, wherein the memory unit stores workflow data related to a workflow for performing a task, the workflow comprising at least a first workflow package for a first part of the task, wherein the computing device assigns the first workflow package to the first apparatus, and to provide workflow data related to the first workflow package to the software agent of the first apparatus, to receive a problem solution request from the software agent, to perform, upon reception of the request, a workflow modification process; and to provide the customized data to the software agent of the first apparatus.

A dual-use spring attached to a small satellite that performs two common functions for small satellites including operating as a communications antenna for the small satellite, which eliminates the need for a separate antenna deployment step, and ejecting the small satellite from a modified deployment container mounted on a launch vehicle. The deployment container is modified by removing a conventional deployment spring and pusher plate, which increases available container space.
