What is a 3U CubeSat?
CubeSats are a class of research spacecraft called nanosatellites. CubeSats are built to standard dimensions (Units or “U”) of 10 cm x 10 cm x 10 cm. They can be 1U, 2U, 3U, or 6U in size, and typically weigh less than 1.33 kg (3 lbs) per U. These CubeSats are flown as auxiliary payloads on previously planned missions.
How much does a 3U CubeSat cost?
The cost of a triple (3U) unit is 25,000 euros. Assuming this cost is shared with two other CubeSats, this means the cost is 8333 euros per satellite = US$11,000. The total cost for this phase is therefore estimated to be US$16,000.
How big is a 3U CubeSat?
The new specification currently governs CubeSats larger than the 3U size. This includes a 6U (12 kg, 12 x 24 x 36 cm), 12U (24 kg, 23 x 24 x 36 cm) and 27U (54 kg, 34 x 35 x 36 cm)….
| Element | Mass (estimated) | Remarks |
|---|---|---|
| Adapter structure | 85 kg | Structure plus cabling |
| Dispensers/P-PODs | 25 kg | Assumes 8 @ 3 kg (3U) |
How big is a 6U CubeSat?
12 x 24 x 36 cm
The new specification currently governs CubeSats larger than the 3U size. This includes a 6U (12 Kg, 12 x 24 x 36 cm), 12U (24 Kg, 23 x 24 x 36 cm) and 27U (54Kg, 34 x 35 x 36 cm).
Who uses CubeSats?
Cubesats are miniature satellites that have been used exclusively in low Earth orbit for 15 years, and are now being used for interplanetary missions as well. In the beginning, they were commonly used in low Earth orbit for applications such as remote sensing or communications.
How many CubeSats are there?
CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. As of August 2021, more than 1600 CubeSats have been launched and more than 90 have been destroyed in launch failures.
What can CubeSats do?
Uses typically involve experiments that can be miniaturized or serve purposes such as Earth observation or amateur radio. CubeSats are employed to demonstrate spacecraft technologies intended for small satellites or that present questionable feasibility and are unlikely to justify the cost of a larger satellite.
Are CubeSats useful?
CubeSats are now commonly used in low Earth orbit for applications such as remote sensing and communications. But as engineers become more familiar with the technology, CubeSats are beginning to venture farther afield.
How long do CubeSats last?
Initial conditions were considered depending on some usual physical and orbital characteristics (weight of the satellite, semi-major axis, eccentricity and inclination of the orbit), for a CubeSat remain in orbit for a period not longer than 25 years.
Are CubeSats geostationary?
CubeSat operations have steadily advanced from Low Earth Orbit (LEO) in 2003 to Geosynchronous Orbit (GEO) in 2019. This method ensures that CubeSats developers are utilizing standards during the design phase as well as standard operating procedures when on orbit to help minimize the load on the SSA system.
How long do CubeSats stay in orbit?
25 years

How much does a nanosatellite cost?
The average nanosatellite costs around 575,000 USD to launch. In comparison, a satellite of a “standard” mass and size can cost over 575 million USD.
