Everybody ready for today's record-setting orbital launch?
Japan will be launching the SS-520-4 at 23:48 UTC today, breaking their own record for smallest orbital launch vehicle, putting a 4kg micro-satellite into orbit using an adapted sounding rocket a mere 9.5 meters in length!
Pictured are the SS-520-4, Japan's previous record holder Lambda-4S, and the iconic V2 rocket.

How is this even remotely cost effective?

Sometimes, you just need to put something in orbit, and it can be very small. You're not interested in price per kilogram, you're interested in price per launch, hitting the desired orbit, and when you can get it launched.
Piggybacking on a large rocket launch means no control over schedule or orbit. An affordable small rocket is highly desirable.
There's also the potential for low costs through economy of scale. Big, expensive rockets launch a few times per year, so their production isn't highly automated and involves a huge amount of costly touch labor and individual inspections. Small, affordable rockets might launch a few times per day and come off an assembly line, with quality control done through sampling.

livestream started. Amateur feed, so probably boring until the countdown starts.

I did not know. Very cool - thanks!

yeah, delayed to the 14th due to excessive high level winds.
