The sprite is powered by its own solar panel and is capable of broadcasting signals back to Earth. It launched on 18th April 2014 as part of a NASA mission to resupply the International Space Station. Due to issues with deployment (see mission update, below) the mission failed. There is a related project to build [[Project:Hackney Space Centre|Hackney Space Centre]]. For the latest information see the [[Mailing List|mailing list]]. |

| + | |||
| + | HackSat launched on 18th April inside the KickSat satellite. KickSat | ||
| + | started out in an orbit of 299 by 331 Kilometers at an inclination of | ||
| + | 51.65 degrees. This is a low orbit and subject to a significant amount | ||
| + | of drag. | ||
| + | |||
| + | Sixteen days after launch, KickSat was due to deploy HackSat and its | ||
| + | other satellite sprites. The delay was required by Nasa to avoid | ||
| + | interfering with ISS operations. This meant HackSat would have began | ||
| + | orbiting on 4th May. | ||
| + | |||
| + | On 30th April the watchdog microcontroller that runs the KickSat timer | ||
| + | reset, probably due to a cosmic ray. This pushed the deployment of | ||
| + | HackSat out to 16th May. Attempts to manually deploy HackSat via the | ||
| + | uplink failed: the KickSat batteries never reached a high enough | ||
| + | voltage to enable the uplink receiver. | ||
| + | |||
| + | Since launch signals from KickSat have been regularly received by | ||
| + | ground stations around the world. Recent orbital predictions suggested | ||
| + | that re-entry was likely 13-14th May. No stations have reported | ||
| + | hearing KickSat overnight, so it seems very likely it has already | ||
| + | re-entered. | ||

| + | === Schedule === | ||
| + | After several launch delays, KickSat is now in low Earth orbit. | ||
| + | |||
| + | HackSat and the other sprites will be deploying ~ 20:00 UTC on 4th May. | ||
| + | |||
| + | Our satellite is contained with the bigger KickSat. 128 sprites are loaded into it. It has the names of contributors engraved on it, including "London Hackspace". You can see a [http://zacinaction.github.io/kicksat/engraving_photos/KickSat_minusY_Zoom2.jpg photo of the actual KickSat], complete with our engraving (we're on the bottom row, 4th from the right). | ||
| + | |||
| + | === Software Payload === | ||
| + | HackSat broadcasts a simple set of data on temperature, magnetic field and angular velocity. It will also broadcast the HackSpace URL: http://hack.rs | ||
| + | |||
| + | If you're interested in trying to receive the signal from HackSat (and | ||
| + | the other KickSat sprites) yourself see [https://github.com/zacinaction/kicksat/wiki/Setting-Up-A-Ground-Station setting up a ground station]. | ||
