The Atlas V family tree goes back to the late 1950s as one of the US\u2019s first ICBMs. The military quickly determined liquid-fueled rockets were better suited in the satellite business and the Atlas launcher was born. Throughout its history it was used in project Mercury, Gemini, and for countless scientific and national security missions.<\/p>\n<h4 class=\"wp-block-heading\" id=\"h-what-is-an-atlas-v-421\">What is an Atlas V 421?<\/h4>\n<p class=\"wp-block-paragraph\">The modern version of the Atlas is a two-stage design with up to 5 solid rocket boosters on the side. It is optimized for national security launches but has several commercial contracts with Boeing and Amazon. This variant of the rocket is a 421, this can be decoded easily. The 4 stands a 4-meter fairing, a 5-meter faring is available. The number 2 stands for the number of SRBs are on the side, this can be between 0 and 5. Finally, the 1 stands for the number of RL-10 engines on the Centaur upper stage, the addition of a second engine is available although it has only flown on the Boeing Starliner OFT mission.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-the-weather\">The Weather<\/h2>\n<p class=\"wp-block-paragraph\">Weather from the Space Launch Delta 45 shows near-perfect weather for today\u2019s evening launch. With a 90% probability of good weather at the time of launch and the only concern being cumulus clouds. Today looks like a beautiful day for a launch.<\/p>\n<p class=\"wp-block-paragraph\">The backup day of tomorrow looks just as good with only a slight decrease in the probability of good launch weather down to 80%. Both today and tomorrow have no additional risk criteria that are of concern.<\/p>\n<figure class=\"wp-block-image wp-block-image--obfuscated\"><img decoding=\"async\" src=\"https:\/\/spaceexplored.com\/wp-content\/themes\/ninetofive\/dist\/images\/default-spaceexplored-related-guide.png\" alt=\"Site default logo image\" loading=\"lazy\"><\/figure>\n<h2 class=\"wp-block-heading\" id=\"h-atlas-v-launch-updates\">Atlas V Launch Updates<\/h2>\n<p class=\"wp-block-paragraph\"><strong>May 18th, 2:08 PM EDT:<\/strong> The Centaur\u2019s upper stage RL-10 engine has restarted to circularize the orbit.<\/p>\n<p class=\"wp-block-paragraph\"><strong>May 18th, 1:52 PM EDT:<\/strong> The RL-10 engine has shut down after its first burn.
