Many of you have asked what makes the Overview One space-tolerant, safe, and robust enough to fly to the International Space Station (ISS). Having the safest possible batteries is a key element in accomplishing that goal. Therefore we have replaced the LiMnNi batteries normally found in GoPro’s with Cell-Con LiFePO4 battery packs.

The key features present in LiFePO4 batteries include high cycle life times (in excess of 2000 recharges), non-explosive thermal runaway, greater chemical stability, and greater tolerance to temperature extremes. This means the Overview One can be recharged twice a day for 2.7 years, will not release dangerous chemicals into the ISS should the battery system fail, and will better survive the transition to operations outside of the ISS.

More info on “Guidelines on Lithium-ion Battery Use in Space Applications” by NASA can be found at http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090023862.pdf

Tech updates will be released every 3 days. The next topic...stress analysis.

Making space hardware open source comes with many challenges and benefits as outlined by our friends at DIY Space Exploration and Mach 30. Making sure not to get arrested for International Traffic in Arms Regulations (ITAR), Export Administration Regulations (EAR), and Missile Technology Control Regime (MTCR) for US federal violations is key :)

That said, SpaceVR’s Overview One hardware will be posted on Mach 30’s Open Design Engine after the Kickstarter campaign. As a preview to that, you can view and comment on our Go Pro interface PCB, which connects 2, 4, 6, 8, or 12 cameras together enabling synced content capture. To make the Overview One Go Pro interface PCB space tolerant, key manufacturing specs include using reduced tin whisker solder paste, Roger 4003 or Thermoset PCB material, ULTEM 1010 & ABS-ESD7 3D printed material and NASA outgas compliant via paste PHP-900 Series IR-10FE. Lets get to space as a community of artists, engineers, and explorers!

Tech updates will be released every 3 days. The next topic... Space Batteries.

Tech Update III: The ISS Data Bottleneck & Explore The Overview One

For any space mission, data rates limit the amount of data that can be sent back to Earth in a timely fashion. Data rates are determined by the distance between the transmitter and receiver, antenna design and sizing, the frequencies and encoding used, as well as many other less significant factors. These factors are tabulated in a “link budget” which helps determine the data rates which a space mission is capable of. You can review the SpaceVR link budget for the Overview One Mark V HERE

The ISS talks to Earth at a few different data rates, limited mostly by the small size of its antennas and available electrical power. While sufficient for most communication, this is not so for the huge amounts of data needed to construct a 24K VR video. For this reason, we have chosen to save the Overview One’s raw video on SD cards which can be returned to Earth in a SpaceX Dragon capsule. The raw video can then be stitched into a VR video on the ground, allowing us to get around the ISS bottleneck. Lower resolution compressed data, on the other hand, is a different story (more on that in Tech Update VIII: 360 Stitching Software). 

Tech updates will be released every 3 days. The next topic… Space Tolerant Open Source Space Hardware. You can ask other technical questions in the comments below and on Twitter using the hashtag #AskSpaceVR, which we will answer in our mid campaign Q&A video and Reddit AMA.

Tech Update II: GoPros in SPACE!

Space is unforgiving. Between thermal extremes, vacuum, and increased radiation, most consumer electronics will not last long. Astronauts have to take extra laptops to the ISS for this reason. Spacecraft electronics have to be hardened against radiation and extremes of heat and cold. 

Which is why the recent NASA spacewalk footage is so amazing. Besides the high-resolution video, a first for a spacewalk[1], the GoPro camera used wasn’t really designed for space. It was designed for adventure. Thanks to that experience, we are confident that the GoPro is the right camera to use in the Overview One. GoPros having a sign-off from NASA and real space heritage goes a long way towards making this project a reality. You do have to replace the GoPro batteries, and we have budgeted for and sourced ITAR certified 2000 mAh space heritage battery packs from Cell-Con (More on that inTech Update V: LiFePO4 Batteries) 

Tech updates will be released every 3 days. The next topic… the ISS data bottleneck. You can ask other technical questions in the comments below and on Twitter using the hashtag #AskSpaceVR, which we will answer in our mid campaign Q&A video and Reddit AMA.
