First experiment of Astral Travel in Samadhi to the planet Mars was performed on 10th August, 1975. A report of his 21 observations was published, out of which 20 observations were fully corroborated by the spaceship Viking 1, after 21st July, 1976, i.e. almost one year after his observations. The 21st observation about ancient water and moss on the Mars was established by another spaceship, the Pathfinder in 1987, 12 years later.
In his second experiment of Astral Travel on 12th August, 1976, he observed by Clairvoyance the docking of spaceships Viking-1 & Viking-2. Advance observation by him was subsequently confirmed by NASA on 7th Sept. 1976.
In yet another Astral Travel to the planet Jupiter on 27th August 1977 , he made 18 distinct observations on the Jupiter. Spaceship Voyager corroborated his 10 observations in 1979, while the remaining observations are yet to be tangibly proved, may be, through some future space program of humanity.
In 1980, during his Samadhi, he saw a man on a celestial body in another Solar System . He has published his findings through this transcendental feat in his book , 'Scientific Explanation of the Katha Upanishad.'
USA had planned to launch a spaceship to the Saturn to reach & study the planet in 2004. He, through his transcendental visit to Saturn visualized that the Saturn is a ball of three types of revolving heavy gases, having purple, yellow and black shades. The famous ring of Saturn is made of some material like slurry or mud along with floating rocks. There are no land marks on the Saturn because there is no formation of land. In the third edition (2003) of his autobiography ' Brahmarashichi Samaranayatra', he has published his observations about the planet Saturn.
