A couple years ago #NASA had an article answering a common question about how many digits of pi they use for their calculations. While pi can be computed (with ever-increasing amount of effort) to almost any number of digits, for navigation of space probes they only need 16. jpl.nasa.gov/edu/news/how-many #PiDay #space #math #astronomy #tech

NASA JPL EducationHow Many Decimals of Pi Do We Really Need? – News | NASA JPL EducationWhile world record holders may have memorized more than 70,000 digits of pi, a JPL engineer explains why you really only need a tiny fraction of that for most calculations – even at NASA.

Is it Mars or is it Titan?

Another one of those surreal dark sky images, captured from Broom's Point, about 600m downhill from the western rim outside Jezero Crater.

FOX WeatherSpaceX finally launches rocket mission in effort to get delayed astronauts homeThe crew of NASA’s SpaceX Crew-10 mission launched from the Kennedy Space Center around 7:03 p.m. local time on Friday. NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov will replace the previous crew, including Suni Williams and Butch Wilmore. Williams and Wilmore were part of the Boeing Starliner crew, which was slated to return to Earth in June, but NASA deemed the mission too risky, and the spacecraft returned with a crew onboard.

Arp Bot 🤖

Image of Arp 293, also known as NGC 6285 and NGC 6286, from the Atlas of Peculiar Galaxies by Halton Arp (1966).

In the original catalog, it was in the category: Double and multiple galaxies - Wind effects. NGC 6285 (left) and NGC 6286 (right) have roughly equal masses. Their mutual gravitational attraction pulls streams of gas, stars, and dust from the galaxies as they interact.

A grainy, black and white image of a pair of interacting spiral galaxies. The galaxy on the right is seen nearly face-on. It has a bright disk. At the edges of the disk are two short, faint, wide spiral arms. The galaxy on the left is seen edge-on. It's disk forms a line. In the center of the galaxy, the circular bulge emerges on either side of the disk. The black background of space is dotted with stars and small background galaxies. The black background of space is filled with white dots, which are foreground stars.
