Two more launches: PSLV (Resourcesat 2A) and Delta IV (WGS 8)

Two more successful launches this week!  First off, yesterday India placed the Resourcesat 2A spacecraft into orbit aboard a PSLV XL rocket from Satish Dhawan Space Centre on Sriharikota Island.  The satellite will fly on a polar orbit (inclination 98.7 degrees) to study resource utilization, soil contamination, water usage, and so forth across the Indian subcontinent.

Then this evening, a rare Delta IV Medium rocket (the “stick” configuration of the Delta IV, seldom used because although it is highly reliable, it is also highly *expensive*) placed the Wideband Global SATCOM (WGS) 8 satellite into geosynchronous transfer orbit.  WGS-8 will serve military customers, providing both targeted and full-disk communications beams in variety of frequency bands.  It is the most capable military commsat launched by the USAF, capable of serving multiple bands simultaneously and even switching between them on the fly.

And here’s a rather different perspective on the launch — a deceptively peaceful one, shot by a drone over nearby Cocoa Beach.  The audio is from the operator’s cellphone, so mostly records the sound of the ocean waves rolling in.  You have to listen carefully to hear the distant warbling roar of the rocket.
