However, given the relative immaturity of ballistic missile technology at that time, neither country achieved usable ballistic missiles for some time.
Even those will only be used for calibration; "physics collisions" with usable results will start some time after that.
"First light," or the first actual fully calibrated, usable image from the satellite, is expected some time in June.
A 1 1,000 high-voltage probe (Tektronix P6015A, Beaverton, OR, USA) measures the voltage across the DBD tube, and the Rogowski-type Pearson current monitor (model 110, 0.1V/A−1%, 1 Hz to 20 MHz, 20-ns usable rise time; Palo Alto, CA, USA) measures the total current flowing through the DBD tube.

Overalls are great for this because they can have long pants or shorts which makes them usable any time during the year.
"On the train, you've got power outlets and Wi-Fi, you can talk on the phone — it's usable time," said George Hamlin, an aviation writer and airline consultant who frequently rides Amtrak between Washington and New York.
Mr. Carney hopes that global guidelines — and they need to be simple enough, he said, to be usable in the time frame in which the authorities must often operate — will make future resolutions cleaner and more predictable.
It's starting with a physical card the way Netflix started with DVDs — because they're more widely usable for the time being.
And with the changes, there's even a chance that Amazon will be able to revitalize to Goodreads audience, who may have stopped regularly engaging with the service as lagged to keep up with modern user interface trends, and failed to deliver more usable features over time.
