Dear Medium followers,
I’m not active here anymore. If you’d like to keep following my writings, here are links to my blogs, their email subscription, and RSS feeds.
My Dad wrote this on the board today. Above is Neil Armstrong’s “One Small Step..” quote in Gujarati.
I assure you I had little role getting him excited for today’s Blue Origin launch of humans. Say what you want about commercial space, it does get people excited in new ways. 🚀
A friend recently told me, “(Her) Blog feels like home.”
I couldn’t agree more.
That led me to think of analogies for social platforms and websites in terms of how much power and freedom they actually give you over your content. If we think of your content on the internet in terms of physical places, this is what they are like.
If you’re serious about what you write, create, or put out on the Internet, get a domain…
Many people think that the Moon is just a gray ball of rock in the sky. Surprisingly, many scientists share this notion too. I once had a physicist tell me the Moon is boring. So I’m writing this article to summarize the immense scientific and exploration value of our Moon.
The bootprints of Apollo astronauts who walked on the Moon are still there. That’s because the Moon is airless and so things stay unchanged for years. This single fact makes the Moon a geological time capsule.

ISRO’s first space telescope, AstroSat, and NASA’s Chandra X-ray observatory, also space-based, have together found a black hole that spins at a rate close to the theoretical maximum. Designated 4U 1630–47, the black hole weighs about 10 solar masses — a stellar mass black hole, not one of the gigantic ones found at the centers of most galaxies.
Stellar mass black holes are formed when a giant star collapses under its own gravity, The entire mass is crushed to a single point called the singularity…
This article was originally published on The Planetary Society as a contribution for the Apollo 11 landing anniversary. This is a mirror of the same.
Where did the Moon come from? The origin of our cosmic neighbor is a fundamental question in planetary science. From Galileo’s first telescopic observations of the Moon to humans walking on its surface, our understanding of its origins has come a long way. Yet it is far from complete.
There are multiple hypotheses that have attempted to explain how the Moon came to be. …
The location of the landing site poses multiple constraints on how the spacecraft orbits are designed, including the launch/landing time and everything in between. Let’s take a look at the constraints imposed by the landing site first, followed by the nature of the lunar orbits.
A lunar day is equivalent to 14 Earth days (between 70 N/S) and we want to maximize the surface operations time post-landing. Landing at local…
