At just 2.6 tonnes, is this the lightest ever land based satellite launcher to reach the launch pad?
Does that include the "Stage Zero" booster?

The SS-520-4 does not have a "stage zero" booster.

It seems that the T-0 target will be 23:48 UTC as announced during the pre-launch press conference today.

Here's a 360 degrees panorama of the sounding rocket pad with the rocket on top: https://theta360.com/s/mP8YDVNIIcPfmpQhzXWtgVOvE

Is the pad newly built for this launch? Prior launches looked like they flew from a truck-based platform.

After looking at the above linked panorama & satellite views of Uchinoura, it appears to be built on the site of the old Mu pad.

I do not think so, as the Mu pad is still on its site, although somewhat modified for Epsilon.

There is indeed a new rail launcher at this site. I do not know, if it was built on purpose for this special launch.

Hmmm...

According to http://spacelaunchreport.com/padsites.html (Hat tip, Ed!) there are two pads at Uchinoura.  One is the former M-V pad, now rebuilt for Epsilon.  The other is on the hill above it.

Ed has it labeled as the former Mu pad - perhaps it is a sounding rocket facility instead?

That what Ed has labled "former Mu pad" is the Sounding rocket pad (Lambda, S-310, S-520). This facility has apparently two launchers -  the one sheltered in the concrete structure (used for S-310) and the open air launcher (for S-520 and SS-520). The latter was originally only a concrete pad for a mobile launcher, but has now a firmly installed rail launcher (as seen in the SS-520-4 images)

It may have been built for the NS-520 and NL-520 versions as the rail is long enough to accommodate their lengths.

It was there in 2014 for the S-520-29 launch (image below from the ISAS website)

S-520-27 launched from the mobile launcher close to the position of the new launch rail, which would put the construction some time between December 2012 and August 2014:

S-520-28 also used the mobile launcher, but from within the dome.


I've also found what appear to be the official names for the pads at Uchinoura: the sounding rocket pad (which will be used for this launch) appears to be called the KS Centre, and the Mu/Epsilon complex is called the Mu Centre.

JFY2014, the old launch platform was changed to new system. (not for SS-520 only)
