In July this class the semi - secluded X-37B space planeset a recordfor the longest time in orbit for a craft of this variety . Now it is finally back , jell offsonic boomsacross Florida as it land .
The X-37B looks like a beat - up version of the oldSpace Shuttle . However , with no crowd nor the need for the necessities that sustain them , it can weigh almost 100 time less and stick in space far longer .
" Since the X-37B ’s first launch in 2010 , it has shattered records and provided our res publica with an unrivaled capacity to rapidly screen and incorporate unexampled space technologies , " Boeing ’s Jim Chilton said in astatement .

During the mission the Naval Research Laboratory ’s Photovoltaic Radiofrequency Antenna Module move around sunlight into electricity for microwave transmission to the earth . This idea , widely discussed in the 1980s , isexperiencing a renaissanceas the falling cost of solar power and space launches get it closer to cost fight .
To increase its utility on this , the 6th mission , the X-37B carried a service mental faculty attached to its rear for the first sentence . The mental faculty necessitate to separate to allow for safe atmospherical re - entry , but in a probable dig at China’sout - of - control Long March protagonist , Air Force Secretary Frank Kendallsaid ; “ The deliberate style in which we conduct on-orbit operations – to include the service mental faculty garbage disposal – speaks to the United States ' commitment to secure and creditworthy outer space practices , especially as the issue of growing orbital junk threatens to impact global distance operations . ”
Many of the experiments the X-37B carries have military involvement , such as the FalconSat-8 built in collaborationism with the Air Force Research Laboratory , leading to surmise it is actually a undercover agent plane or weapon . If so , it ’s deep undercover , withanalysts arguingit is too gentle to track and too ungainly on re - entry for either purpose .
Public parts of the missionary station included a long - term subject on how time expose to space actinotherapy affects the viability of seeds , and testing of radiation syndrome shielding thermic coating materials for NASA .
After this mission , the X-37B has now spent a sum of 3,774 day in quad , during which time it has flown more than 2.1 billion kilometers ( 1.3 billion mile ) .
“ The X-37B stay on to agitate the bounds of experiment , enabled by an elite government and industry team behind the scene , ” said the Air Force ’s Lt . Col . Joseph Fritschen in astatement . “ The power to deal on - orbit experiment and fetch them home safely for in - depth analysis on the land has shew valuable for the Department of the Air Force and scientific biotic community . The addition of the servicing faculty on OTV-6 allowed us to host more experiments than ever before . ”
The plane ’s operator may not have made too many protagonist in fundamental Florida , however . neighbour of the Kennedy Space Center probably get used to tatty noises , but a sonic bonanza like a shot prior to its 5:22 am touchdown is n’t the way most people wish to awake up on a Saturday . TheTampa Bay Timesreports residents about 50 kilometers ( 30 miles ) west of Kennedy saying their “ whole house shook ” , and there was a “ atomic number 16 - smell fog ” after the plane passed . In keeping with the partial secretiveness about the projection , occupier had no warning .
