Design error may have caused SpaceX rocket explosion in 2015: NASA

Technology
A design error may have caused a SpaceX rocket to explode mid-air in June of 2015, according to a NASA report that was released Monday. The unmanned rocket was headed to the International Space Station to deliver 4,000 pounds of supplies. It burst into flames above Cape Canaveral in Florida just 139 seconds after its launch, and SpaceX concluded that the explosion was most likely due to a faulty steel part called a strut. "SpaceX chose to use an industrial grade (as opposed to aerospace grade) 17-4 PH SS (precipitation-hardening stainless steel) cast part (the 'Rod End') in a critical load path under cryogenic conditions and strenuous flight environments," NASA said in its report. NASA also concluded the steel strut was implemented without sufficient testing. "The implementation was d...

UK has new highest peak after measurement error

Technology
Britain has a new highest mountain after new data showed measurements from old overland surveys were inaccurate.It was thought until this point that Mount Jackson was the tallest mountain in the British Antarctic Territory at 3,184m (10,444ft) above sea level.However, new satellite data by British Antarctic Survey (BAS) shows Mount Hope is the tallest mountain, at 3,239m (10,654ft).The new data reveals Mount Hope as being 55m taller than Mount Jackson and 377m higher than previously thought.The discovery was made during work by BAS to update planning maps for pilots operating in Antarctica.New high-resolution satellite measurements, accurate to within five metres, show there are several errors in the old overland surveys.Adrian Fox, head of mapping and geographic information at BAS, said: ...
