5/11/2023 0 Comments Atlas v risingThe first stage tanks no longer use stainless steel monocoque pressure stabilized "balloon" construction.The main differences between the Atlas V and earlier Atlas I and II family launch vehicles are: Thrust can be augmented with up to five Aerojet AJ-60A or Northrop Grumman GEM 63 strap-on solid rocket boosters, each providing an additional 1.27 MN (290,000 lb f) of thrust for 94 seconds. The booster operates for about four minutes, providing about 4 MN (900,000 lb f) of thrust. It is powered by one Energomash RD-180 main engine burning 284,450 kg (627,100 lb) of liquid oxygen and RP-1. The Atlas V first stage, the Common Core Booster (CCB), is 3.8 m (12 ft) in diameter and 32.5 m (107 ft) in length. ![]() LMCLS continued to market the Atlas V to commercial customers worldwide until January 2018, when United Launch Alliance (ULA) assumed control of commercial marketing and sales. ![]() The vehicle operates from SLC-41 at Cape Canaveral Space Force Station (CCSFS) and SLC-3E at Vandenberg Space Force Base. Air Force Evolved Expendable Launch Vehicle (EELV) program and made its inaugural flight on 21 August 2002. The Atlas V was developed by Lockheed Martin Commercial Launch Services (LMCLS) as part of the U.S. The standard payload fairings are 4.2 or 5.4 m (14 or 18 ft) in diameter with various lengths. AJ-60A SRBs were used originally, but they were replaced in November 2020 by Graphite-Epoxy Motor (GEM 63) SRBs. Strap-on solid rocket boosters (SRBs) are used in most configurations. The Star 48 upper stage was used on the New Horizons mission as a third stage. The Centaur upper stage is powered by one or two American RL10 engine(s) manufactured by Aerojet Rocketdyne and burns liquid hydrogen and liquid oxygen. The first stage is powered by a Russian RD-180 engine manufactured by Energomash and burning kerosene and liquid oxygen. As of 5 August 2022, 21 launches remain.Įach Atlas V launch vehicle consists of two main stages. In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. It is America's longest-serving active rocket. Atlas V is also a major NASA launch vehicle. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. The data shown are the latest available, updated annually.Atlas V is an expendable launch system and the fifth major version in the Atlas launch vehicle family. The “Global Temperature” figure on the home page dashboard shows global temperature change since 1880, compared to NASA’s 1951-1980 baseline. Short-term variations are smoothed out using a 5-year running average to make trends more visible in this map. Dark red shows areas warmer than average. Dark blue shows areas cooler than average. ![]() The animation on the right shows the change in global surface temperatures. NASA’s analyses generally matches independent analyses prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration (NOAA). The year 2020 tied with 2016 for the hottest year on record since recordkeeping began in 1880 (source: NASA/GISS). Nineteen of the hottest years have occurred since 2000, with the exception of 1998. This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. Earth’s global average surface temperature in 2020 tied with 2016 as the hottest year on record, continuing a long-term warming trend due to human activities.
