A powerful Delta 4 Heavy rocket carrying a U.S. spy satellite finally launched into orbit. The spacecraft lifted off from California’s Vandenberg Air Force Base at 5:11 p.m. EST on Saturday. The mission canceled many times since early December due to technical errors and adverse weather conditions. The National Reconnaissance Office (NRO) will operate the NROL-47 spacecraft. It is an agency that produces and manages the United States’ spy satellites. The organization operated America’s fleet of investigation and intelligence-gathering satellites. United Launch Alliance, an association of Lockheed Martin and Boeing, stated that the spacecraft consists of three booster rocket carrying a shipment for NRO.
No other details are available about the satellite’s activities. The external boosters of the spacecraft separated after four minutes of take-off. The central booster also triggered a successful ignition. Delta IV can carry a payload of more than 14,000 pounds directly to geosynchronous orbit. Thus, it is a top rocket to deploy government satellites into space. ULA representative said the missile has a total of 36 space missions under its belt, and it is working since 2002. It is 233-foot-tall and capable to produce more than 2.1 million pounds of thrust. The rocket is powered by Aero jet Rocket dyne RS-68A main engine and weighs about 1.6 million pounds when the fuel tank is full.
On Dec. 19 the mission canceled due to a hydrogen leak in one of the engines. Before that, another launch scheduled on Dec. 8 axed due to technical problems. The current liftoff also delayed by two days. Firstly, due to strong winds and secondly due to an issue in ground system valve. It is the first launch of ULA in 2019. The agency aims to launch the U.S. Air Force’s WSG-10 mission in upcoming weeks. It will use another Delta IV spacecraft, and the mission is set to take place on 13th March at Florida’s Space Launch Complex-37.
