A rocket carrying a U.S. Space Force satellite into orbit may have punched a jam in Earth ’s upper ambience , after lifting off with just 27 time of day ' notice — a novel record for the brusk amount of metre from bring the go - ahead to actually set up .
Firefly Aerospace , a caller contracted by Space Force , launch one of its Alpha rockets from Vandenberg Space Force Base in California on Sept. 14 at 10:28 p.m. local sentence , Live Science ’s sister siteSpace.com reported . The launching was not publicized or live - stream , build it a complete surprise to thespace explorationcommunity .
The separation of the first and second stages of the Firefly Aerospace Alpha rocket after launching on Sept. 14. Fuel burned during this part of the rocket’s flight may have created a hole in the ionosphere.
The rocket was carrying Space Force ’s Victus Nox satellite ( Latin for " curb the Nox " ) , which will run a " space domain knowingness " mission to help Space Force keep tabs on what is happening in the orbital environs .
The surprise rocket initially caught people ’s eye after create anenormous exhaust plumethat could be seen from more than 1,000 miles ( 1,600 km ) off . But after the plume dissipate , a feeble red glow remained in the sky , which is a revealing sign that the rocket created a hole in the ionosphere — the part of Earth ’s atmosphere where flatulence are ionized , which stretches between 50 and 400 miles ( 80 and 645 km ) above Earth ’s airfoil — Spaceweather.com cover .

The Alpha rocket lifts off from Vandenberg Space Force Base on Sept. 14.
This is not the first " ionospheric hole " observed this year . In July , the launch of aSpaceXFalcon 9 rocketcreated an enormous rip - red patch above Arizonathat could be determine for hundreds of geographical mile .
rocket create ionospheric holes when fuel from their 2d phase George Burns in the middle part of the ionosphere , between 125 and 185 mile ( 200 and 300 km ) above Earth ’s surface , Live Science antecedently report . At this height , the carbon dioxide and water vapor from the rocket ’s exhaust movement ionized oxygen atoms to recombine , or form back into normal atomic number 8 molecules . This process turn on the molecules and lead them to let out energy in the form of light . This is similar to howaurorasform , except the dancing lights are triggered by solar radiotherapy heating up gases rather than their recombination .
The yap get no terror to people on Earth ’s control surface and naturally close up up within a few hour as the recombined flatulency get re - ionized .
The upper stage of the Alpha rocket releases the Victus Nox satellite into orbit around Earth.
Firefly Aerospace wasawarded the Victus Nox contract in October 2022but was told that it would have to launch the satellite at an unidentified point in the future with less than 24 60 minutes ' admonition . To accomplish this , the launch squad had to update the rocket ’s trajectory software , capsule the satellite , get the satellite to the launching diggings , place it in the rocket and go through the concluding checks within that time , harmonize to a companystatement . Even then , spoilt weather stand for they had to set up afterward than planned .

The purpose of the mission was to " demonstrate the United States ' ability to speedily identify an plus in orbit when and where we need it , see we can augment our space capabilities with very small posting , " Lt . Col . MacKenzie Birchenough , an officer with Space Force ’s Space Systems Command , said last yr when the mission was first denote .
