What is Space Computing?
Until now, when people talk about cloud computing, it’s usually understood that the cloud is a
metaphor for groups of remote, networked servers.
When Lance Parker (CEO of company ConnectX) talks about “space computing” he means it
literally: physical servers operating in outer space.
ConnectX is a startup company based in Los Angeles, USA working on a way to take corporations’
data out of the cloud and into the final frontier. If this company succeeds, it could revolutionize the
way we store, transmit, and analyze information.
We can think “Cloud computing” evolution is
“Cloud in the space” or simple “Space Computing”

Advantages of “Space Computing”
1. Save energy problems, data centers use up 10% of the world’s electricity
Putting servers in space could potentially remedy the energy problem, since they could be powered by free, plentiful solar
radiation, so a real IT Green solution.
2. No need to freeze the servers
In the space, the weather is -180°C so no need to have refrigeration systems running 7 day x 24 hours. In addition in the space
there are not humidity, so no need to control this too.
3. Fast processing because the space environment
Space environment would be advantageous for spinning disk drives. Zero-gravity allows the drives to spin with less resistance,
and the extreme cold in space means the servers could process faster without overheating.
4. A very good cost-effective to launch a server into space
Nowadays the cost of put satellite up into space is not expensive (for small satellites is less than U$S 100,000)

Disadvantages of “Space Computing”
1. There are no need of be compliance or to follow legal topics because satellites are not inside
nations legislation area
A big risk about privacy data use because no need to have legal compliance, no national legislation apply in the space.
2. Storing large amounts of data in space is not feasible with the actual transmission rates
Beam information using electromagnetic waves, this method of transmission is much slower than using wire
3. Space waste or small meteorites could destroy our satellites
In the space there are more and more waste (satellites out of service, small pieces, etc.) which could damage or destroy the
satellites where the servers are.
4. Shadow problems about coverage
To solve coverage problems because of the "shadow", it will be necessary to have 2 or more satellites working together as a
“cluster” so more expensive solution.
5. Uplink & Downlink are not symmetric
After download the data, it is necessary to transfer in the ground.

Disadvantages of “Space Computing”
6. Extremely expensive maintenance
To repair a server in a satellite would be obviously extremely expensive. A very difficult issue to solve. Can the potential reduction
in long-term maintenance costs really offset the massive expense of actually getting their servers into orbit? And what about
upgrading capacity?
