India’s IRNSS-1H navigation satellite, which failed to reach its intended orbit following its Aug. 31 launch, is expected to re-enter the Earth’s atmosphere in 40-60 days.

India has issued its biggest-ever global tender to procure more than 230 new multi-role maritime helicopters, in an attempt to address the growing shortage of helicopters available for deployment on its warships.
