Indian media reported over the weekend that the Mars Orbiter Mission has passed some senior review, and has been approved to proceed toward a launch date of October 28, with the launch taking place in the afternoon. This is one week later than previously planned; I haven’t found any reason cited for the delay. The launch period closes November 19. The same article states that the spacecraft is now undergoing vibration testing and that there will be a pre-shipment review on Thursday. Assuming the spacecraft passes that review, it is expected to be shipped to the launch site at Sriharikota a week from today, on September 30. The launch vehicle is being assembled, and the spacecraft will be stacked onto the rocket on October 10.
