Close-up of Bennu’s north pole
Click for full image.
The OSIRIS-REx science team has released a very high resolution image taken of Bennu’s north pole region. To the right is the most interesting part of that image, cropped by me to show here.
This image shows a region near asteroid Bennu’s north pole on the terminator line between the asteroid’s day and night sides. The OSIRIS-REx spacecraft’s MapCam camera obtained the image on Feb. 20 while in orbit around the asteroid from a distance of 1.1 miles (1.8 km). At this distance, each pixel covers approximately 4.5 inches (12 cm) of Bennu’s surface. The largest boulder, located slightly left of the center, measures around 52 feet (16 meters) across, which, for scale, is the length of the trailer on a semi-truck.
In other words, if this was a truck stop along an interstate highway, you could see the driver getting out of that semi to head inside for dinner.
The spacecraft right now is not doing much science work. They are in what they call the Orbital A phase of the mission, where they are in a very low orbit along the terminator line between night and day — generally a mile above the surface — and are using this orbit to give the engineering team practice maneuvering at such an orbit while they transition from using the stars to navigate to using landmarks on the surface.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

1.1 Miles is less than 6000 feet up – atmospheric oxygen is enough at that that altitude. (10K for masks or sealed cabin) And yes, I know Bennu ain’t got no* Oh-Two, I’m making a point about how amazingly close the craft is to the surface. Every time I see reports like this I am amazed at the precision we can achieve from so far away.

Good stuff.

Thanks, Wayne. Let’s see, we’re precise to 1 mile at a distance of 12 million miles, don’t have my calculator handy but I think that’s something like 0.0000008 percent !
Col Beausabre–
highly enjoy your stuff!
Correct me if I’m mistaken; we’re talking Newtonian-physics with only minor General Relativity corrections, correct?
