“Success to take an image with main camera”

Now, we try to take a fine image with main camera.
Below image is the latest one.
(Original image is
greenish by camera's nature.)
(All the images which we have taken are shown image gallery.)

We have taken the image at West Coast, considering that there is not much cloud in usual, and we could get the
image that enable us to verify the ground.

The curve line at the bottom part of image may be coast line.

impress the coast line

We tried to find the place of the image ,,,, and we can find the place!!

A new age of remote-sensing by super small satellites is coming !!
We will adjust the parameter with analysis of this image.

“Success to deploy the extensible boom”

We have succeeded to deploy the extensible boom!!
Extensible boom is optical telescope composed of flexible architecture. This structure is our new idea for taking images at high resolution with super small satellite (Detail is on About project page).
If this boom will work expectedly and take the image with main-camera (NAC), we will complete our main mission.

We use sub-camera's picture for confirming that boom has been deployed. Below pictures are "before deployment","after deployment". The figure identified on the upper right side is boom structure.
We can find the shadow which was not exist before deployment.
As a reference data, we also show the image (boom was deployed) taken on ground test.

before after ground

We estimate that boom has been deployed with these three pictures.
Additionally, the evidence is found in angular rate data.
