PHOBOS CUBESAT PROJECT
We will take high-resolution 1 cm (0.4 in) / pixel images of Mars's moon Phobos.
We will take high-resolution 5 cm (2 in) / pixel images of Earth's moon.
Please support this project to make it all happen.
Phobos CubeSat project details
Phobos CubeSat project details.
Our project aims to send a small Cube Satellite to the Mars’s moon Phobos and Earth’s moon and take High-Resolution pictures from low orbit. We chose to use COTS (commercial off-the-shelf) product to build our CubeSat to cut the cost. As the cost to get to the Moon’s orbit is still too high, we decided to pack more fuel and get there slowly from LEO.
Our planned launch date is the second half of 2023.
We have seen many pictures from the Moon, but it usually takes a long time to access them. There are also groups of people who think that some look altered, modified or even completely hidden from us. They believe that the organizations who take these pictures change some of them because of the infamous Brookings Report or other agendas. On the other hand, the other group of people believe that there is nothing to it. They think that shadows or camera processing errors can explain everything. Who knows?
Our Cube Satellite should be welcomed and supported by everyone who wants to know the truth, regardless of what they think about the official public pictures or NASA and other space organizations. This is an open project that everyone can participate in. All data will be available in RAW format in real-time to everyone. Anyone will be able to ensure that there are no secrets, no delays and no modifications.
The CubeSat images will either confirm that there is nothing unusual on our Moon and Phobos, or confirm some alien presence there. Maybe we will capture unique alien structures in high resolution, or even aliens having some party there, who knows.
In any case, all of us will be able to see the highest resolution pictures of all questionable places, and we will be able to settle this controversy.
Some Interesting Anomalies.
In any case, I think that if we all get together, we can finally find out the truth and resolve this controversy. We can get pictures of all strange objects on the far side of the Moon and on Phobos ourselves, without censorship and any alterations.
We will be able to orbit the Earth’s moon as close as 30 km from the surface and take Panchromatic pictures with a spatial resolution of around 30 cm (12 inches) / pixel. Or, with the optional camera, we can get a spatial resolution of an incredible 5 cm (2 inches) / pixel.
On Phobos, we will get a spatial resolution of around 1 cm (0.4 in) / pixel.
All the data will be immediately and freely available to everyone via the Internet. Every time we receive new data, we will announce it on Social media and Telegram.
This project is not about any country or individuals. It should be a project where all of us get involved, and all of us take credit.
I hope that we all get together and make it happen. We need as much input as we can from everyone. We would like you to join our team to make this project as good as we can.

Some of our team members are also candidates to fly on the dearMoon mission, enabled by open-minded visionary, entrepreneur Elon Musk who is founder, CEO, and Chief Engineer at SpaceX and financed by Japanese billionaire Yusaku Maezawa. Wouldn’t it be great if the first private trip of EARTHLINGS around the Moon would take with them the first Cube Satellite with the capability to take pictures with up to 5 cm (2 in) resolution build jointly by EARTHLINGS volunteers? This resolution is about ten times higher than NASA’s Lunar Reconnaissance Orbiter. But then the CubeSat will fly to Mars’s Moon Phobos and take even higher resolution pictures of about 1 cm (0.4 in) there. Sound’s interesting, doesn’t it? Let’s hope that we can get enough support to make this project a reality.
If we get our CubeSat directly to the moon, we will have extra fuel on board to make many more orbital changes, as we will not use any propellant to fly from LEO to the Moon orbit.
Please join the Phobos CubeSat project on Indiegogo, and do not forget to spread the news on social media. Any donation, even $1, will help to make this project happen. We also welcome volunteers to join our team.
What is CubeSat
Some or all of these upgrades will be possible if we collect enough money over our target on INDIEGOGO campaign, or get some discount on our CubeSat’s equipment or delivery to the LEO or directly to the Moon.

X-Band Transmitter is a high data rate satellite module operating in the 8.025 – 8.4 GHz frequency band. This band is allocated by the ITU for Earth Exploration Satellite Services (EESS, Spaceto-Earth). The transmitter is designed to work in accordance with the DVB-S2 ETSI EN 302 307 standard. Other standards are also available upon request, for example CCSDS.
The form factor of the X-band Transmitter is built around the PC-104 connector standard which is the most common for CubeSat systems. The module has two modes of operation – Load mode and Transmit mode. In the Load mode the device is recording data into its internal memory (2x16GB) from the OBC or directly from a dedicated payload. It is intended for periods when the satellite is not communicating with the GS. Therefore, in this mode the module automatically switches off all unnecessary electronics and consumes less than 0.27 W. In
the Transmit mode the device sends the loaded data through the radio channel. The optimum output power is 32 dBm and can be regulated from 27 dBm to 33 dBm with a 1 dB step. The power consumption in Transmit mode with 32 dBm RF output power is 12 W. Four interfaces are available on the PC-104 connectors – I2C, CAN, UART and SPI. They are used for setting the communication parameters (e.g. operation mode, frequency, output power, symbol rate) and transferring the payload data. The RF output connector to the antenna is a 50 Ohm SMA female jack. The system has an easily accessible mini-USB connector primarily intended for setting
up the module and performing tests while on the ground.
The small overall dimensions of the metallic box combined with the robust HW architecture of the X-band
Transmitter makes it a perfect choice for CubeSat or nanosat missions.

- Maximum Transmit Power: 2W;
- Transmit data rate: up to 50Mbps;

The band is in the amateur range and can be configured in the whole allocated spectrum – 430-440 MHz. Furthermore, they feature 2 configurable data rates, which can be programmed onorbit.
The output power can also be tuned in order to maximize the power budget depending on orbit altitude, ground station and desired minimum elevation angle for communication. The device is fully encapsulated in an aluminum shell that takes care of heat dissipation from the power amplifiers and significantly reduces the EMI.

- Sensitivity: -113 to -121 dBm;
- Interfaces: UART @ 9600bps / I2C (optional);
- Type: Half-duplex;
The antenna is designed to cover the amateur satellite band 435-438 MHz. It has a circular polarization and uses a redundant burn wire mechanism with feedback for deploying the radiating rods.
It can also be used for the commercial band (400-403 MHz) with less than 2 dB overall loss.

The Chameleon imager takes advantage of the space-qualified electronics of the Gecko imager and combines this with high-performance optics to maximize imaging capability in small form factor CubeSats. High capacity, high-performance mass storage is integrated into the compact design. The opto-mechanics have been optimized to fit within the available volume of CubeSat deployers thus providing maximum volume to accommodate the functionality required for your high-performance CubeSat mission.
Images are captured directly to the integrated mass storage. No need for additional payload data storage capacity on the satellite. Data can be streamed directly to a transmitter or to an onboard computer as required. Reliable operation is achieved by using a combination of proprietary hardware and ruggedized optics.
