High-Level Project Summary
We chose "Virtual Planetary Exploration 2.0" as the theme of this SpaceAppsChallenge, and developed a product that will allow future astronauts to explore the surface of the planet in a meaningful way, and created a 3D model.Humanity aspires to space.I believe that most of you who are participating in the SpaceAppsChallenge also think this way, as do we.In 1969, when Neil Armstrong became the first man to set foot on the moon aboard Apollo 11, what he did first was to leave behind a quote that said "That's one small step for a man, one giant leap for mankind".Now in 2021, what would be the first thing you would do when you landed on the moon?It would be a SELFIE.

Detailed Project Description
Besides the fact that today is the age of social networking, taking selfies on the Moon or on the surface of an extraterrestrial planet has several advantages.
First of all, when future researchers look back at the photos, they will be able to see at a glance whose recorded images they are.
Secondly, when you pull the camera closer to capture that moment, something happens off-screen. Selfies allow us to capture such unconscious angles of view.
That's why we developed "Satsue-chan," a selfie stick designed for the human in space environment.
However, there are various challenges in taking a selfie on the moon.
First of all, on the point of view from hardware engineering, there are cosmic rays pouring down, a vacuum space, and heat buildup due to the lack of air convection.
On the user experience side of things, there is no light source other than the natural light from the sun. It is also difficult to operate tools in a space suit. There are also various issues such as the possibility of occupying valuable space on the spacecraft.
Satsue-chan is the solution to all those issues!
We will show you how Satsue-chan can withstand the harsh space environment.
First of all, it is designed against cosmic rays. By using materials that block cosmic rays, such as lead, the CPU in the camera is protected from adverse effects caused by bit invert, etc.
In the vacuum countermeasure, the sealed case containing the camera is filled with nitrogen gas to prevent various problems that may occur in a vacuum space.
Sealing with nitrogen gas also serves as a thermal countermeasure. To prevent cosmic rays, after taking a selfie, you can return to the spacecraft and open the case to easily release the heat.
The LED tape on the edge of the case can also function as a ring light, so it makes you look more beautiful even in space where there is only natural light.
In terms of user experience, the Satsue-chan has a number of nice features. First of all, the grip part is made of Velcro, which allows you to firmly hold Satsue-chan with minimum grip strength. Since it is made of Velcro, there is no need for special manipulation when letting go, and it is easy even in a space suit.
The power for the camera and ring light can be controlled by the switch on the bottom of the grip. To take a picture, press the thumb switch once, and to take a movie, press and hold the same thumb switch.
By incorporating a telescopic structure, the limited precious space in the spacecraft can be used in a meaningful way.
By storing the battery in the handle, it also reduces the negative effects of the leaded camera case attached to the head, which makes it difficult to balance.
With our space-optimized selfie stick, your journey in space will be even better.
Make your planetary exploration worth it.
