I started to speak about the business. Raadha was hearing everything without responding. I asked her about working with me. She didn’t respond. I as...ed her again, still, she didn’t respond. Meena asked her, “Why ain’t you replying?”. Raadha didn’t know what to speak. I could see that she was feeling guilty.Suddenly it struck me that these sisters didn’t hide anything from each other.

Ion propulsion could be used for a manned mission.
