Top secret X-37B space plane will fly next month using an 'experimental propulsion system', reveals the US Air Force

  • X-37B space drone will take off on its fourth secret mission on May 20
  • Theories ranged from it being a space bomber to destroying satellites
  • The flight will test a system that makes satellites easy to manoeuvre
  • This is probably a small part of the vehicle's true mission, say experts

The mystery of the top-secret X-37B space drone has baffled military experts for decades.
Theories have ranged from it being a space bomber ready to attack, to a secret probe on a mission to 'take out' spy satellites.
Now, in an unprecedented disclosure, the Department of Defense has revealed details about the X-37B latest mission, which is due to take off on May 20.

X-37B'S MYSTERY MISSIONS 

The U.S. Air Force's unmanned X-37B space plane has flown three secret missions to date.
Each time it has carried a mystery payload on long-duration flights in Earth orbit.
The spacecraft looks similar to Nasa's space shuttle but is much smaller. The X-37B is about 29ft (8.8m) long and 9.5ft (2.9 m) tall.
It has a wingspan of just less than 15ft (4.6 m). At launch, it weighs 11,000lbs (4,990kg).
The craft is taken into orbit on a rocket but lands like the space shuttle by gliding down to Earth.

'[We] are investigating an experimental propulsion system on the X-37B on Mission 4,' Captain Chris Hoyler, an Air Force spokesman, told Space.com.
'The Air Force Rapid Capabilities Office will also host a number of advance materials onboard the X-37B for Nasa to study the durability of various materials in the space environment,' Hoyler added.
Spaceflightnow.com revealed more details of the flight, which is described as a 'hall thruster electric propulsion test.'
It is intended to improve performance of the units onboard Advanced Extremely High Frequency (AEHF) military communications spacecraft, officials said today.
AEHF satellites' Hall thrusters are 4.5-kilowatt units that use electricity and xenon to produce thrust for moving satellites in space.
The benefit of using electric propulsion is that its xenon fuel weighs much less than traditional hydrazine.
This technology could help in the development of technologies to control satellites with better accuracy.
However, experts claim that refining an advanced manoeuvring thruster is probably just a small part of the vehicle's true mission set.
One leading secrecy expert previously told DailyMail.com that the drone is 'very likely' be used to test technologies that will increase spying capabilities of the US.

Like a shuttle, X-37B is blasted into orbit by a rocket. However, it lands using a runway like a normal aircraft. The X-37B is too small to carry people onboard, but does have a cargo bay similar to that of a pickup truck, which is just large enough to carry a small satellite

TOP FOUR CONSPIRACY THEORIES

The space plane is a spy plane: The leading theory appears to be that the unmanned space plane is a shuttle-shaped surveillance vehicle. 
It could be a space bomber: This is the least likely theory, according tot Seven Aftergood, a secrecy expert at the Federation of American Scientists. He claims the US doesn't need this capability. 
It is on a mission is to 'take out' satellites: This activity would be easily traceable, making it unlikely to stay a secret. 
The X-37B deploys spy satellites: Instead of destroying them, the theory suggests that the space plane's orbit matches up to where deployed satellites would work best for spying on other countries.


'The US government has a bottomless appetite for sensitive information,' said Steven Aftergood, a secrecy expert at the Federation of American Scientists.
'As powerful as our intelligence satellites may be, they also have their limitations - most notably the limitations imposed by their orbital parameters.
'It's conceivable that a spy plane would introduce new versatility into overhead reconnaissance.'

The X-program has bounced between several federal agencies, Nasa among them, since 1999.
The plane has been in space for a total of 674 days, far more than its two previous flights which lasted 225 and 469 days.
The program's first mission launched in April 2010 and landed in December that year.
The second space plane took off on March 2011 and came back to Earth in June 2012.
According to X-37B manufacturer Boeing, the space plane operates in low-earth orbit, between 110 (177km) and 500 miles (800km) above earth.
By comparison, the International Space Station orbits at about 220 miles (350km).
