Making reliable software is exceptionally time-consuming and requires a lot of hard work. Building a working ground station and making sure that it can track a satellite moving at\u00a0 8km\/s above our head is tough. Making sure that the science instrument can reach the level of precision required for detecting the transit of Beta Pic b, and creating a database reliable and efficient enough to store all the data is a challenge all by itself. And today, we are recalled that launching a satellite into orbit &#8212; the only thing we were taking for granted so far &#8212; is also terribly complex and difficult&#8230;<\/p>\n<p>The Indian rocket PSLV-C39, which lifted-off on schedule from Sriharikota, suffered from some sort of malfunction (apparently, the fairing did not separate), leading to the failure of the mission.
