There is a 100% chance of acceptable weather conditions during the launch window, according to the weather team at Vandenberg, but conditions could be foggy.<\/p>\n<p>The two-stage Alpha rocket is designed to loft up to 2,200 pounds (1,000 kilograms) into a low-altitude orbit, or up to 1,388 pounds (630 kilograms) of payload to a 310-mile-high (500-kilometer) sun-synchronous polar orbit.<\/p>\n<p>The Alpha is one of many privately-developed small satellite launchers new to the market, and the kerosene-fueled rocket will initially launch from Space Launch Complex 2-West at Vandenberg, a military base around 140 miles (225 kilometers) northwest of Los Angeles.<\/p>\n<p>Firefly moved in at the SLC-2W launch site after the final United Launch Alliance Delta 2 rocket took off from the pad in 2018.<\/p>\n<p>In addition to upgrading the Delta integration building and support facilities at the site, Firefly installed a brand new launch mount and transporter-erector at the pad. The Delta 2 was stacked vertically on the launch pad, while the Alpha launcher is assembled horizontally, then rolled out and lifted upright for launch.<\/p>\n<p>Last month, Firefly completed a static test-firing of the Alpha rocket\u2019s four Reaver main engines at SLC-2W, following a simulated countdown in which the launch team loaded kerosene and liquid oxygen propellants into the vehicle.<\/p>\n<p>Four Reaver engines on the first stage will generate more than 165,000 pounds of thrust at maximum power, and a Lightning engine on the second stage will produce more than 15,000 pounds of thrust.<\/p>\n<figure id=\"attachment_53172\" aria-describedby=\"caption-attachment-53172\" style=\"width: 720px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-53172\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/FIREFLY-FIRSTLAUNCH-10.jpg\" alt=\"\" width=\"720\" height=\"510\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/FIREFLY-FIRSTLAUNCH-10.jpg 720w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/FIREFLY-FIRSTLAUNCH-10-300x213.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/FIREFLY-FIRSTLAUNCH-10-678x480.jpg 678w\" sizes=\"(max-width: 720px) 100vw, 720px\"><figcaption id=\"caption-attachment-53172\" class=\"wp-caption-text\">Firefly\u2019s Alpha launch vehicle stands at Space Launch Complex 2-West on Wednesday.

The renamed company emerged from bankruptcy proceedings in 2017&nbsp;under new ownership.<\/p>\n<p>Noosphere Ventures, a Menlo Park, California-based firm led by managing partner Max Polyakov, now funds Firefly\u2019s rocket development program.<\/p>\n<p>Firefly\u2019s other projects beyond the Alpha launcher include the Beta rocket, which will use upgraded engines to haul heavier payloads into orbit. Firefly also has ambitions for a robotic lunar lander, a space tug powered by electric thrusters, and a reusable spaceplane.<\/p>\n<p>Firefly is also developing a second launch site would be located at the disused Complex 20 launch pad at Cape Canaveral Space Force Station in Florida.<\/p>\n<p>For it\u2019s first test flight, Firefly is carrying a suite of educational, artistic, and research payloads. The company offered free launch capacity on the first Alpha test flight through a program Firefly calls the&nbsp;Dedicated Research and Education Accelerator Mission, or DREAM.<\/p>\n<p>The Alpha rocket take off from Vandenberg to target a 186-mile-high inclined 137 degrees to the equator. The unusual orbit, called a retrograde orbit because the rocket will travel against the Earth\u2019s rotation, will require the Alpha launcher to head southwest over the Pacific Ocean on a track passing just south of Hawaii.<\/p>\n<figure id=\"attachment_53173\" aria-describedby=\"caption-attachment-53173\" style=\"width: 900px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-53173\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/alpharetrograde.jpg\" alt=\"\" width=\"900\" height=\"502\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/alpharetrograde.jpg 900w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/alpharetrograde-300x167.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/alpharetrograde-678x378.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2021\/09\/alpharetrograde-768x428.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\"><figcaption id=\"caption-attachment-53173\" class=\"wp-caption-text\">This map illustrates the unusual southwest launch trajectory targeted on Firefly\u2019s inaugural test launch.
