a computer that measured the rotation of the lander hit a maximum reading , knocking other calculations off track . The erroneous information generated an estimated altitude that was negative that is , below ground level , the ESA said in a statement . Oh boy . Looks like the measurement data register was full and the program confused it for a signed number causing reading to be interpreted as negative and the rover to think it ' s under ground . As a embedded software engineer , I am amazed this happens at this level . This is one of the most important things to take care of when dealing with analog sensors and arithmetic using signed and unsigned numbers <| sep |> Oh jesus . Team officials said team jerseys will be available to order after the first of the year and they don ' t expect to receive them until the summer of 2017 . My actual thought process What ? Why the hell would it take a year and a half . to . Shit , it ' s almost 2017 , isn ' t it ?
