The latitude of the Great Pyramid of Giza coincidentally matches the speed of light when expressed in modern units, but it's simply a coincidence. The Ancient Egyptians did not work in meters, and the speed of light was not measured until centuries after the construction of the pyramids. While the alignment is intriguing, it is not evidence of ancient knowledge of the speed of light.
French company Latitude has raised $30 million in a Series B round, bringing the total amount raised to $55 million, to develop its small launch vehicle, Zephyr. The funding will support the production and testing of the rocket, with plans for its first flight in 2025 and a doubled payload capacity in 2028. The company aims to become a market leader by the end of the decade and is also focused on expanding its workforce and enhancing its industrial capabilities.
The author reflects on the dark and gloomy winter days in Seattle, expressing frustration at the lack of daylight and the government's inaction. They highlight that even eliminating Daylight Saving Time wouldn't solve the problem, as daylight continues to shrink by three minutes per day. Comparing Seattle's daylight hours to other major cities like Paris and London, the author finds solace in the fact that they are not alone in facing this issue. They conclude by reminding readers that the days will eventually get longer and that the current darkness is temporary.
Bodø in Norway gets on average 36.5 more minutes of daylight per day than Sydney, Australia due to refraction, hemisphere, and latitude. The Northern Hemisphere gets a longer summer than the Southern Hemisphere due to the elliptical orbit of the Earth. The Arctic Circle gets the most sunlight with an average of 12 hours 40 minutes per day, while the South Pole gets the least with an average of 12 hours. The summit of Mount Forel, Greenland, gets 5,052 hours of daylight a year, more than anywhere else on the planet.
North Korea's attempt to launch a military spy satellite failed due to an abnormal ignition of the second stage; Arianespace signed a launch contract for the Earth observation satellite Kompsat-6, which will fly into orbit on the European light launcher Vega C; ClearSpace has contracted Arianespace to launch its first debris-removal mission to capture and deorbit a 100 kg piece of space debris; Northrop Grumman won a $45.5 million contract to launch a small weather satellite in 2025 using its Minotaur 4 rocket; French launch startup Latitude is pushing its Navier rocket engine to the limits in a new test campaign.
Rocket Lab's Electron rocket will be modified to serve as a hypersonic test bed, allowing payloads of up to 600 kg to be deployed into trajectories five times greater than the speed of sound. Meanwhile, French launch company Latitude has initiated a "significant recruitment campaign" to support the development of its Zephyr smallsat rocket. China's commercial space industry is bustling, with approximately 10 commercial rocket startups that could conceivably launch a rocket within the next 12 to 18 months.
