SRE – MISSION PROFILE
• SRE will be in orbit for nearly 10 days during which it will perform Micro- Gravity experiments
• Subsequently it will be moved from Circular orbit to Repeating Elliptical Orbit (REO)
• It will de-boosted from REO and will be made to Re-enter and impact nearly 140 km off the coast of SHAR
• SRE will be recovered from the Sea
