JAXA-manifested rideshare of eight separate spacecraft that includes educational small sats, an ocean monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna that can be packed tightly using origami folding techniques and unfurled to 25 times its size.

The satellites were originally planned to launch with RAISE-4 on a Japanese Epsilon-S rocket, but the Epsilon-S was heavily delayed due to test firing failures.

The 8 satellites are:

* MAGNARO-II
* KOSEN-2R
* WASEDA-SAT-ZERO-II
* FSI-SAT2
* OrigamiSat-2
* Mono-Nikko

Join us live on 9 April, as we broadcast the launch of the European-Chinese Smile mission.
 
Smile will head to space on a Vega-C rocket from Europe's Spaceport in French Guiana.
 
This stream will include live launch footage from the launchpad and control room, as well as real-time interviews with people involved in the mission and its launch.
 
For the first time, Smile is going to reveal what really happens when charged particles from the Sun crash into Earth's magnetic shield.
 
It carries an X-ray camera to make the first X-ray observations of how exactly this shield responds to the solar wind, and an ultraviolet camera to watch the resulting northern lights for 45 hours at a time.
