According to the just posted NASA Spaceflight news item Japanese sounding rocket shoots for record-breaking orbital launch:
Japan conducted another attempt to launch a miniature satellite via a modified SS-520 sounding rocket Saturday, a little over a year after its first attempt failed to achieve orbit. Liftoff, from the Uchinoura Space Centre, occurred at the opening of a ten-minute window at 14:03 local time (05:03 UTC).
- Why is the rocket launched at such a steep angle?
- Is it an optical illusion, or was it launched from the top of that titled structure (and if so, why did that need to be tilted as well?)
fyi The original launch is discussed at length in Will JAXA try again to launch TRICOM-1 with the “world's smallest orbital rocket” SS-520-4 again?
