India’s space agency is inviting students in science and engineering to apply for internships at the Indian Space Research Organisation (ISRO) unit in Thiruvananthapuram. The ISRO Inertial Systems Unit (IISU) has issued detailed guidelines for students who want hands-on exposure to space technology during their ongoing degree programs. Applications must reach IISU by March 15 for the May–July internship block and by September 30 for the October–December session.

The internships will take place at IISU’s facility in Thiruvananthapuram and will run between 21 and 45 days. Students can apply by sending the completed form by post or email to the program planning and evaluation group under the management and information systems area. Selected students will work only in unclassified sections of the center.

The opportunity is open to Indian citizens who are pursuing degrees in science and technology fields connected to space programs. Eligible courses include BE, BTech, ME, MTech, MSc, integrated MSc, PhD, BSc in Physics or Chemistry, and BS-MS programs in the same subjects. Undergraduate applicants must have completed at least four semesters, while postgraduate and doctoral candidates must meet academic requirements based on their previous qualifying degree.

Applicants must maintain a minimum of 60 percent marks or a CGPA of 6.32 on a 10-point scale. Each student is allowed only one internship during a single degree program. IISU also requires a detailed biodata that lists education history, technical skills, project work, and any earlier internships.

The agency expects a large number of applications, and not all candidates will receive a position. Officials advised students to consider other institutions as backup options because facility limits restrict how many interns IISU can host at one time. The final decision will be sent to the principal or head of the applicant’s college.

The internship does not include any stipend or financial support. Students will need approval from their college principal or department head before submitting the application, and incomplete forms will not be considered.

Internships at IISU attract strong interest because the center plays a key role in India’s launch vehicle guidance and navigation systems. These technologies help rockets maintain stable flight paths and accurate satellite placement. Exposure to such work offers students a rare chance to observe how space hardware and software operate in a real mission environment.
