Facebook Live is looking to tap its billion-plus user advantage and built-in social and group features to gain an edge on rivals like Periscope. As such, it has revealed live streaming within groups and events, real-time reactions, invitations to watch video with friends and a live map showing video in 60 countries. Later today, the social network will launch the service in LA (on Facebook Live, of course) with appearances by Mark Zuckerberg and product chief Chris Cox. If you’ve been using Live, Facebook will give you a heads-up as to when to tune in to the broadcasts.
The biggest and most logical feature is the ability to broadcast live within groups and events. If you’re putting on a concert, race or charitable event, for example, it makes infinite sense to be able to stream key moments to a ready-made captive audience. The feature will let friends and family who are subscribed but can’t make it in person can still experience the fun at a distance. Creators also get five new Instagram-like filters, and Facebook will soon let you doodle directly onto live video.

Satellite manufacturing today is a lengthy, meticulous process; its high tech nature, and the cost in time and money make advances slow compared to sectors like the mobile industry. But an explosion in demand for connectivity and other space services is driving the need for ever-more capable satellites. It is at this crossroads, that bold new ideas are being forged.
