1.RTG battery

RTGs are built to last. Its sturdy and compact design makes it an ideal energy source for remote operations. They can withstand the harsh environments and frigid temperatures of deep space travel for decades, have no moving parts and require no maintenance, and have proven to be extremely reliable. In fact, some RTGs launched decades ago, are still in operation today like the Voyager mission that first started in 1977.

RTGs work by converting thermal energy into electrical energy through devices known as thermocouples. The natural decay of plutonium-238 produces heat that is then transferred to one side of the thermocouple. The temperature difference between the fuel and the atmosphere allows the device to convert this heat into electricity. The most current RTG model, the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG), provides approximately 110 Watts of electrical power when freshly fueled.

RTGs are used on NASA missions where other options such as solar power are impractical or incapable of providing the power that a mission may need to accomplish its scientific or operational goals. Sometimes referred to as “nuclear batteries,” RTGs are not fission reactors, nor is the plutonium the type that is used for nuclear weapons. More than two dozen U.S. space missions have used RTGs since the first one was launched in 1961.

2. GPHS

The General Purpose Heat Source module, or GPHS, is the essential building block for the radioisotope generators used by NASA. These modules contain and protect the plutonium-238 (or Pu-238) fuel that gives off heat for producing electricity. The fuel is fabricated into ceramic pellets of plutonium-238 dioxide (238PuO2) and encapsulated in a protective casing of iridium, forming a fueled clad. Fueled clads are encased within nested layers of carbon-based material and placed within an aeroshell housing to comprise the complete GPHS module.

Each GPHS is a block about four by four by two inches in size, weighing approximately 3.5 pounds (1.5 kilograms). They are nominally designed to produce thermal power at 250 watts at the beginning of a mission and can be used individually or stacked together.

It Provides electricity and heat that can enable spacecraft to undertake scientific missions to environments beyond the capabilities of solar power, chemical batteries, and fuel cells.

This technology is capable of producing electricity and heat for decades under the harsh conditions of deep space without refueling. All of these power systems, flown on more than two dozen NASA missions since the 1960s, have functioned for longer than they were originally designed.

3. How to implement the solution?

The automoaton spacecraft, on its last trip to Venus, consumed 25.70 watts of energy in 2.3 hours.

If the vehicle needs to stay on the surface of Venus for 60 days to 16000 Watts.

So, one of GPHS provides the spacecraft with 250 Watts, which is enough to make the vehicle works, but we provide it with two of GPHS, because it has a high-temperature limit which is 700 collisios, so we can avoid any battery damaging by switching work between them when one of them get close to the limit.

We were really happy when we knew that we would be one of the teams that would be attending the hackathon, we started the opening sessions which were really helpful, and then we started working in the dedicated room which was organized and prepared to work on the challenge Moderators helped us and supported us, making our Hackathon journey easier
