Vikram takes movie of Pragyan rover as it roves
Click for movie.
Using one of Vikram’s lander cameras, engineers have produced a short movie of India’s Pragyan rover as it rotated to avoid a small crater about ten feet ahead.
The picture to the right is from that 16-second movie, near its end. It appears that the engineers operating Pragyan were unhappy with almost any route ahead from its present position, as they rotated Pragyan almost 360 degrees, and even attempted forward motion at one point and then resumed rotation.
It is not clear if any of the craters visible in this picture are the crater that caused the detour. The movie however does provide a sense of scale. Pragyan is small, but it is able to maneuver easily using its six wheels.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A politically correct, but nonetheless valid, point about the emigration of India’s best and brightest outside the country.

Opinion The unsung heroes of India’s moon landing offer a lesson on brain drain
India needs more heroes like Sreedhara Somanath than it needs entrepreneurs like Satya Nadella.
Did I hear you say, “Who?”
No offense to Nadella, the otherwise brilliant Hyderabad-born chief executive of Microsoft. But it’s the low-key Somanath, under whose leadership India achieved its historic moon landing, who should be a role model for Indians. He represents a generation of gifted scientists who chose not to emigrate — and achieved just as much, if not more, in challenging circumstances.
Somanath will never own a cricket team or show up on any Fortune or Forbes lists. He will probably never be called to dine at the White House. And he earns a fraction of what Indian Americans such as Nadella do. But spending just 30 percent more than Nadella’s annual salary, he took India to the moon.
Bob Wilson: You might want to watch that long interview of the co-founder of Skyroot (an Indian rocket startup) posted in yesterday’s Quick Links. It suggests that this brain drain is not as serious as you think, and in fact, India is in a very strong position to achieve great things in the coming decades.
Why such a low resolution picture?
Why such a low resolution picture?
Just guessing here, but maybe because it is streaming from THE MOON. We – and I include myself – are ridiculously spoiled.
Jhon B: I suspect two reasons for the low resolution.
1. This is from a lander camera on Vikram, which was optimized to provide the best information for landing the spacecraft, not for doing high resolution research.
2. The main purpose of this entire mission is engineering, not science. While it has scientific instruments that are gathering data, even there the goal is to test the engineering so that future science-based missions can be designed properly.
