India has been on a roll lately. Just a few short weeks after completing construction on the world’s first solar-powered airport, and also unveiling a big plan to replace all street lights with energy-saving LEDs; the country has now successfully launched its first space observatory — a major milestone for its rapidly growing space program. This launch follows an earlier mission to Mars that sent an unmanned probe last year to study the red planet. India received accolades for its Mars mission, which cost a fraction of similar missions conducted by the US, Russia and other European countries.
India confirmed that a rocket carrying the 1.5-ton mini observatory successfully lifted off on Sunday from the country’s southern spaceport in Sriharikota. “About 20 minutes after a perfect lift-off at 10 A.M. from our spaceport, the rocket has placed Astrosat in the intended orbit,” said mission director B. Jayakumar. The rocket carried both the Astrosat station and five foreign satellites, including one satellite from the US.
Dubbed the “mini-Hubble,” the Astrosat observatory houses a telescope capable of observing distant celestial objects in both visible and ultraviolet light. It also supports the entire X-ray waveband, which will be used to study far off parts of the universe, such as black holes and star magnetic fields. The Astrosat will maintain a low earth orbit of approximately 400 miles for the next five years. In keeping with its reputation for low-cost space engineering, the space observatory cost 1.8B rupees ($26 million) to build.
India’s successful launch was lauded by prime minister, Narendra Modi, who hailed the accomplishment as a sign of the country’s technological progress. During the launch, Modi was in the United States visiting with silicon valley leaders to promote India as a tech-friendly destination.
After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
