While listening in on the air , a squad of researchers from the U.S. war machine ’s Defense Advanced Research Projects Agency ( DARPA ) picked up unexpected disturbances because of a SpaceX rocket plump through the air toward its landing place situation .
DARPA ’s AtmoSense program seeks to utilize Earth ’s ambiance as a globose detector by measuring acoustical and electromagnetic waves circularize through the air , and attempting to decipher them back to a specific noise event that took place on Earth . In doing so , DARPA hopes to be able-bodied to trace underground explosion or other national security threat using the signal detected from the atmosphere .
During its latest round of listening to the atmosphere , a team used AtmoSense to canvas profound wave created by control explosion in New Mexico . While conducting this work , the team behind the program made an unplanned uncovering after note something unusual in the sensor data point .

“ As the squad was depend at the datum , they witness a vast drop in what ’s called total electron content that puzzled them , ” Michael Nayak , political program manager of AtmoSense , say in astatement . “ conceive of that you have urine go through a hose . That ’s a flow of negatron , and if you put your fist in front of the hosiery , you ’ll notice a significant driblet in body of water loudness come out of the hose . ”
After dissect the data , the squad was able to trace the ruffle to a SpaceX Falcon 9 rocket reentry that took position on the same daytime as the test . “ Then they decided to displume other SpaceX reentry datum , across scads of launches , to see if they could spot a similar electron drop , ” Nayak sum . “ The phenomenon is extremely quotable . ”
Using AtmoSense , the squad inadvertently discovered a new technique to identify object reentering through Earth ’s atm , according to Nayak . The researchers behind the program will share the most late results from AtmoSense during an upcoming virtual workshop being held from April 15 to 17 .
Falcon 9 is the hard working projectile in the game , with over 450 missions under its belt . SpaceX ’s Falcon 9 is a part reusable , two - stage rocket that launch payloads into orbit , then come back to Earth for a master landing place , reserve its first degree to be recover and reprocess .
