Four Astronauts have been announced for India's first Gaganyaan Human Space Mission. They are test pilots: Prashanth Balakrishnan Nair, Ajit Krishnan, Angad Pratap and Shubhanshu Shukla. Prime Minister Modi, a visionary, made the announcement. Congratulations, It is a long awaited mission. A critical step to reality of becoming an active player in Artemis Accord as well as ambitious goal of having Indian human space capabilities. When I trained Apollo Astronauts in 1968-1972 period and after receiving Apollo Achievement Award my work began with Apollo 8, I was a rare Indian immigrant working ..read more

I have a problem with Steven Hawking’s suggestion that if time travel were possible there would be loads of tourist from the future here already. There could not be any from the past as a time travel has not been invented yet. As far as the future is concerned there has not been any yet to come back from. How can you touch the future unless you are there. At that stage it becomes the present. We can only be there together. Or can someone explain why my thinking is wrong ..read more

And it’s only 136 light years away. Don’t get me wrong I love the study of space and the tantalizing but, well let’s face it for the foreseeable future, out of reach of our ability to get to another earth like (life sustaining) planet; anywhere. Heck even the shot of sending man to Mars is now, also staring to, slip away once again ..read more

LC vs. SLC

Some are "Launch Complex", others are "Space Launch Complex". Why has this happened? When did this happen? Will they all be named the same way in the future? This post is all I can find on the subject. Personally, I like "SLC" because it can be pronounced "Slick", but it is a little redundant. Which do you prefer ..read more

Starship is the lander for Artemis. Something doesn't add up.

I've been following the various manned space programs worldwide for decades, and there is something so glaringly obvious that I simply do not understand it. Starship is the chosen lander for the Artemis program. But Starship is designed to reach the Moon and Mars from LEO. So why is NASA even bothering with Orion, Capstone and Gateway? SpaceX is even planning to send a Starship on a tourist jaunt around the Moon. It doesn't take a genius to work out that the whole thing could be done with Starships, and probably much cheaper. If there are any articles about this, I'd appreciate someone pointi ..read more

Starship, The Moon & Mars?

I am just reaching out to the community on these related questions: If it might take a Starship lander to reach the moon after 10 refuelings, how is a similar Starship going to make it to Mars? Shouldn't SpaceX try to develop a nuclear engine that would solve not only the refueling problem, but maybe the timeline from e.g. 6 months to 6 weeks or less for the journey? Now if SpaceX does develop a nuclear rocket, will NASA enforce some regulations on procuring nuclear fuel? I wouldn't be surprised if they are quietly going that route right now ..read more
