Secrecy in Space

A Pentagon spaceplane called X-37B zoomed into orbit this week for its eighth mission. When it will come back is a secret. The uncrewed vehicle can spend months or years in space before it re-enters the atmosphere.. That combination of flexibility and endurance has made it a favorite tool for military officials looking to quickly deploy new technologies on the final frontier. A SpaceX rocket launched X-37B on August 21, 2025 from Florida’s Kennedy Space Center. Government and commercial engineers have spent years experimenting with lasers that allow satellites to share large amounts of data in space. The Pentagon is also testing tools like the inertial sensor, which could help improve navigation in situations where Global Positioning System signals aren’t available.

The spacecraft has spent the last five months on Earth after a 434-day mission that included tests of orbital maneuvers known as “aerobraking.” The move helps the vehicle use the drag from the planet’s atmosphere to change its orbit without using much fuel.  Military officials haven’t disclosed many details about the payloads that X-37B carries, but past missions included testing different materials in orbit and an experiment that transmitted solar energy to the ground. Its fifth flight released three small satellites that government officials didn’t acknowledge until they had fallen back to Earth. There’s a global strategic interest in saying what you’re putting in space,” said Jonathan McDowell, a researcher at the Harvard-Smithsonian Center for Astrophysics. If the U.S. hides its satellites, “then the Chinese are going to start doing it too, and that’s not in our interest.”

China now fields more than 1,000 satellites and has developed a range of radio jammers, antisatellite missiles and other weapons capable of targeting Pentagon assets, according to a U.S. Air Force document released in May 2025. It also operates a competing spaceplane, called Shenlong, that has flown several missions.]

Who Will be the First to Colonize the Solar System?

A Chinese spacecraft touched down on grasslands in China’s Inner Mongolia region in June 2024, carrying the first-ever rock samples from the far side of the moon. A scientific breakthrough in itself, the success also advanced China’s plan to put astronauts on the moon by 2030 and build a lunar base by 2035. Such momentum is worrying American space officials and lawmakers, who have their own ambitions to build moon bases.

Unlike the original space race between the Americans and the Soviets, the goal of the U.S. and China isn’t just to make a short trip to the moon. It is to build permanent human outposts on its most strategic location, the lunar south pole. And as both nations gear up to build stations there one day, it is looking likely that tensions in orbit will mirror those on Earth.

Some U.S. officials fear China is planning a land grab. Chinese officials suspect the same of the Americans and are teaming up with Russia and other friendly nations for its south-pole outpost. The successful completion of the Chang’e 6 mission shows that, by one measure, China is ahead for now. Its lunar program has now soft-landed on the moon four times since 2013, the latest mission scooping up rocks near the south pole with robotic arms…

Meanwhile, after a decades-long moon-landing hiatus, two U.S. companies this year launched lunar-surface missions under NASA contracts. One lander tipped on its side after touching down. The other didn’t try to land because of technical problems. At least two more private missions, with funding from NASA, are slated to try to get to the moon later this year….All this is piling pressure upon the world’s most storied space agency. Through its Artemis exploration program, the National Aeronautics and Space Administration plans to conduct multiple landings in the coming years, develop a logistics station in lunar orbit and eventually build permanent camps on the moon’s surface. But Artemis has faced repeated delays and cost overruns while relying on a complex mix of government workers and private contractors…

“Unlike the U.S.-Soviet space race of the 20th century, this new round of competition centers on the water ice at the lunar south pole, with its extraction and use as a common goal,” wrote four scientists affiliated with China’s Academy of Sciences in a paper published in May. “The ability to collect and utilize lunar resources is a mark of national prestige and geopolitical influence. “We’re talking about colonizing the solar system,” said Greg Autry, a NASA official during the Trump administration.

Space Surveillance Telescope: military use

Leave a reply

The most sophisticated space surveillance telescope ever developed is ready to begin tracking thousands of space objects as small as a softball. It’s a boon to space surveillance and science and a new military capability important to the nation and the globe, an Air Force general says.

Developed by the Defense Advanced Research Projects Agency, the Space Surveillance Telescope  (SST) is the most sophisticated instrument of its kind ever developed. It was transferred to the Air Force on Oct. 18, 2016, which has plans to operate it jointly with the Royal Australian Air Force….The Air Force will move the SST to Harold E. Holt Naval Communication Station in Western Australia, operating and maintaining the telescope jointly with the Royal Australian Air Force.The SST also will be a dedicated sensor in the U.S. Space Surveillance Network, operated by the Air Force Space Command.

SST has increased space situational awareness from a narrow view of a few large objects at a time to a widescreen view of 10,000 objects as small as softballs, DARPA says. The telescope also can search an area larger than the continental United States in seconds and survey the entire geosynchronous belt in its field of view –– a quarter of the sky –– multiple times in a night.
