We're having very few applicants this year for ESA's open source summer of code.
The deadline is May 15 midnight UTC.

ESA Summer of Code in Space (SOCIS) is a program run by the European Space Agency. It aims at offering student developers stipends to write code for various space-related open source software projects. Through SOCIS, accepted student applicants are paired with a mentor from the participating projects, thus gaining exposure to real-world software development scenarios. In turn, the participating projects are able to more easily identify and bring in new developers.
