Quasar 3C 273


Quasar 3C 273 is a quasar located in the constellation of Virgo. It was the first quasar ever to be identified. It is the optically brightest quasar in the sky from Earth, and one of the closest with a redshift, z, of 0.158. A luminosity distance of DL = 749 megaparsecs may be calculated from z.

Neptune & Triton. Imaged: Monday 14th August 1989 to Sunday 3rd September 1989.  Closest approach: Friday 25th August 1989. Here are several views of Neptune and Triton obtained by the already then ageing Voyager 2 spacecraft. Despite Voyager 2's age, (was over 12 years since launch) the spacecraft performed magnificently and to this date, these are the best views of Neptune and Triton, and will be for quite some time yet.  Neptne orbits our Sun at an average distance of 30.1 times the Sun to Earth distance or 4.515 Billion KM / 2.804 Billion miles, once every 164 years & 281 days.  Neptune has a mass of 17 times that of Earth, has a mean diameter of 42,244 KM / 30,580 miles and rotates on it's axis once every 16 hours and 7 minutes. Neptune has a deep atmosphere, consisting of 80% Hydrogen, 18% Helium, 1% Methane (gives Neptune the deep blue colour) and 1% trace gases like Ammonia, Nitrogen, etc. Neptune has an average global density of 1.68 times that of water, ...

With 25,000 heat tiles on Starship, would a 1% failure rate mean 250 tiles jeopardize the mission?

With 25,000 heat tiles on Starship, would a 1% failure rate mean 250 tiles jeopardize the mission?  The Starship, a marvel of modern engineering developed by SpaceX, boasts a staggering 25,000 heat tiles designed to protect it during re-entry into Earth's atmosphere. These tiles are not just ordinary materials; they are precision-engineered pieces of technology that play a critical role in ensuring the spacecraft's safety. But what happens if some of these tiles fail? 🤔 Let’s consider a worst-case scenario: a 1% failure rate among those 25,000 heat tiles. Simple math reveals that this translates to 250 tiles potentially compromising the mission. 🚀 Now, that might sound concerning, but it's essential to delve deeper into what a 1% failure rate means in the context of such high-stakes space endeavors.  SpaceX has meticulously tested these tiles, each fabricated from materials like ceramic, to withstand the extreme temperatures experienced during re-entry. The goal is safety...
