Slashdot: NASA Seeks Proposals for Reboosting the Hubble Space Telescope

NASA Seeks Proposals for Reboosting the Hubble Space Telescope
Published on 2026-10-31T18:50:00Z
The Hubble Space Telescope "will plunge back into the atmosphere in the early-to-mid-2030s," reports Ars Technica. So now NASA has released a Request For Information (RFI) "asking commercial companies for ideas on how to reboost, service, or a controlled disposal of Hubble." Specifically, NASA is looking for information about companies' current and near-term capabilities for capturing Hubble and boosting it to an altitude of at least 373 miles (600 km), enhancing the telescope's performance, or guiding Hubble to a controlled reentry. "The requirement includes that the boost and/or servicing mission must not harm the HST and that this mission is expected to occur by 2032," NASA wrote in the RFI. The contractor would be responsible for providing the launch vehicle, servicing spacecraft, mission operations, and "crew if applicable." NASA is not committing to buying a Hubble rescue mission, but officials want to know who might be interested in mounting such a mission, how much it would cost, and which companies would have a realistic shot at reaching Hubble before it falls out of orbit and burns up on reentry. Orbital dynamicists currently predict that it will likely happen in 2033 or 2034 without intervention, but reentry forecasts can change based on solar activity... A reboost to NASA's requirement of 373 miles (600 km) would likely keep Hubble in orbit for at least 25 more years. "NASA last raised the orbit of Hubble in 2002," the article points out, "when the Space Shuttle Columbia visited the observatory for a servicing mission." The final shuttle servicing flight in 2009 did not reboost the telescope's orbit, and with the retirement of the shuttle fleet two years later, Hubble has steadily lost altitude with no way to stave off eventual destruction... NASA's newer flagship observatories, sometimes described as successors to Hubble, are not actually one-for-one replacements. Hubble is tuned to observe the Universe in visible and ultraviolet light, while the Webb and Roman telescopes peer deeper into the infrared Universe. Astronomers will likely have to wait for the launch of NASA's Habitable Worlds Observatory in the 2040s for an improvement on Hubble's visible and ultraviolet vision.

Slashdot: How the FSF Sysadmins are Blocking Botnets with reaction

How the FSF Sysadmins are Blocking Botnets with reaction Published on 2026-07-11T21:47:00Z For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks. How are they fighting back? We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of sma...

Slashdot: Spain-Backed Fund Joins FOSSA's Sovereign Satellite Communications Push

Spain-Backed Fund Joins FOSSA's Sovereign Satellite Communications Push Published on 2026-06-28T22:05:00Z Spanish startup FOSSA Systems "has raised about $10.5 million to expand its connectivity constellation," reports Space News, noting some funding is backed by Spain's government: The support from the Spanish Society for Technological Transformation (SETT) comes a year after the fund injected 14 million euros into Spain's Sateliot , which is also developing a satellite connectivity network with security and defense applications. Spanish private investment firm Kibo Ventures led FOSSA's funding round, the six-year-old venture announced June 24, bringing its total raised to date to nearly 20 million euros. The proceeds will help fuel FOSSA's push beyond the tiny picosatellites it once used to connect low-power monitoring devices toward larger cubesats in low Earth orbit, enabling additional sovereign communications and space-based intelligence capab...

Slashdot: AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age

AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age Published on 2026-03-10T20:00:00Z AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said. The spending will focus on expanding its fiber and wireless networks, including accelerating deployment of fiber broadband, 5G home internet and satellite co...
