ULA begins stacking the Atlas 5 rocket for launch in late June – Spaceflight Now

The bronze first stage of the United Atlas Alliance's next Atlas 5 rocket arrived on Friday at Cape Canaveral's launch pad, where five solid fuel boosters, one Centaur upper-level and one US Air Force will join Communication satellite in the coming weeks before the start on 27 June.

Using a specially equipped trailer, Atlas Space Operations Center at the Cape Canaveral air force station transported the first stage of the rocket to the nearby Complex 41 launcher

Next, ULA personnel will deploy five solid-propellant rocket-propelled aircraft manufactured by Aerojet Rocketdyne. Install Booster to the base of the first level of the Atlas 5. A Centaur upper tier will be lifted onto the Atlas 5, and missile deployment on Cape Canaveral will be limited with the addition of the Air Force's fifth high-frequency communications satellite next month.

The AEHF 5 satellite will be the only payload of the Atlas 5 rocket taking off from Florida's space coast.

The launch is scheduled for June 27 in a two-hour window that will open at 6:00 am CET (1000 GMT).

The Atlas 5 The AV-083 version comes in its strongest version with five Aerojet Rocketdyne-built full rocket boosters for buckling and a 5 meter (17.7ft) diameter payload fairing manufactured by Ruag Space Market brought. This configuration is referred to as Atlas 5-551, which flew nine times before. The five solid fuel engines will give the first stage of the Atlas 5 an extra boost powered by a Russian-made RD-180 main engine that burns kerosene and liquid oxygen propellants.

The combined performance of the boosters and the main engine will give the Atlas 5 a boost of about 2.6 million pounds when it takes off.

The launch on June 27 marks the first Atlas 5-flight of the year and the 80th Atlas 5-takeoff since the launch of the rocket in August 2002. It will be the third of ULA's 2019 mission after two launches by Delta 4 at the beginning of the year.

The AEHF satellites, built by Lockheed Martin, provide secure communications services to the US military and work together in a network that, according to the Air Force, is immune to cyber-jamming and even nuclear warfare. The AEHF spacecraft are located in a geostationary orbit of more than 22,000 miles (nearly 36,000 kilometers) above the equator, using a networked architecture that allows satellites to relay signals without transmitting to ground stations.

The launch of the AEHF 5 satellite comes after the launch of four previous AEHF spacecraft in 2010, 2012, 2013 and 2018, all on Atlas 5 rockets.

As soon as the Atlas 5 rocket, carrying the AEHF 5 satellite, departs from Cape Canaveral, the launch campaign for the following atlas begins. Mission 5 begins in July with the stacking of a new rocket, the Boeing CST-100 Starliner Crew capsule on a test flight without pilots into the orbit to the International Space Station.

The Starliner test flight is due to start at the earliest The 17th of August and the demonstration mission will pave the way for launches with the Atlas 5 rocket and Starliner capsule crew, perhaps by the end of this year.
