A new model helps to figure out which distant planets may host lifeby Daniel Apai Monday, June 2, 2025
Future telescopes, like the proposed Nautilus, could help search the skies for habitable planets. (credit: Katie Yung, Daniel Apai /University of Arizona and AllThingsSpace /SketchFab)The search for life beyond Earth is a key driver of modern astronomy and planetary science. The US is building multiple major telescopes and planetary probes to advance this search.
However, the signs of life—called biosignatures—that scientists may find will likely be difficult to interpret. Figuring out where exactly to look also remains challenging.

What future for SpaceX?by Claude Lafleur Monday, June 2, 2025
Is Elon Musk’s company as promising as it seems?
A Falcon 9 lifts off May 30 from Cape Canaveral carrying a GPS 3 satellite. (credit: SpaceX)The least we can say is that in less than ten years, SpaceX, founded in 2002 by Elon Musk, has transformed the space domain. It now dominates space activities worldwide.
By the numbersOver the past ten years, SpaceX has sent into space nearly three-quarters of all spacecraft launched worldwide (Table 1), while nearly a third of all rockets launched have been its own (Table 2). Since 2020, SpaceX has carried out the majority of launches, now sending more than 80% of all spacecraft.

The origins and evolution of the Defense Support Program (part 4): DSP forever?by Dwayne A. Day Monday, June 2, 2025
The Defense Support Program missile warning satellites first started operating in 1971. They were equipped with an infrared telescope that scanned the Earth as the satellite spun in geosynchronous orbit. Several are still operational today, over two decades since the last launch. (credit: Northrop Grumman)The first Defense Support Program satellite was launched in 1971, followed by 17 more during the next two and a half decades. They provided the United States with a key component of its missile warning system, and each of the satellites added capabilities and had increased lifetimes. The ground systems had also evolved to the point where the satellites could send data to mobile ground stations to provide localized warning of missile attack. The satellite mission had grown beyond simply providing warning of strategic missile attack to become part of various tactical missile defense systems. They also provided intelligence around the world, detecting explosions, fires, and other thermal events. But after two decades, the technology at the heart of DSP was no longer cutting edge.

NASA’s future in the balanceby Jeff Foust Monday, June 2, 2025
Jared Isaacman was days away from being confirmed as NASA administrator, and taking on the largest budget cuts in the agency’s history, when the White House pulled his nomination May 31. (credit: NASA/Bill Ingalls)At the end of last week, the space community was gearing up for more bad news. While there was no formal announcement, NASA was widely expected to release more details about its fiscal year 2026 budget proposal. The White House had released top-level details in a “skinny” budget released in early May (see “Budget cuts and the fraying of international partnerships”, The Space Review, May 12, 2025), but NASA would go into details about how the cuts in the skinny budget would be implemented: which missions and programs would be cancelled or scaled back, and which few lucky ones would be increased.

Space-based solar power: A new frontier in US energy securityby David Steitz and Sowmya Venkatesh Monday, June 9, 2025
As other countries study space-based solar power, advocates of the technology want the United States to step up its efforts. (credit: ESA)Space-based solar power (SBSP) represents a crucial component for meeting tomorrow’s global energy needs. At a congressional staff briefing in Washington last fall hosted by the Space Frontier Foundation, experts warned that the United States risks falling behind China in this emerging technology while highlighting how SBSP could revolutionize energy production.

Starship setbacks and strategiesby Jeff Foust Monday, June 9, 2025
SpaceX’s Starship/Super Heavy lifts off May 27 on its ninth test flight. (credit: SpaceX)It takes a lot to overshadow a Starship launch, but Washington managed to accomplish that at the end of May. The release of the detailed fiscal year 2026 budget proposal for NASA, enumerating cancelled and curtailed missions, followed 24 hours later by the surprise withdrawal by the White House of Jared Isaacman’s nomination to be NASA administrator, were all that people in the space industry were talking about a week ago (see “NASA’s future in the balance”, The Space Review, June 2, 2025).

The long road to near-real-time satellite reconnaissance: a chronologyby Dwayne A. Day Monday, June 9, 2025
Russian strategic bombers destroyed by Ukrainian drones. This image was taken by a Maxar commercial imagery satellite and transmitted to the ground soon after. This capability was first developed by the United States National Reconnaissance Office (NRO) in the 1970s. (credit: Maxar)In late 1976, the United States Air Force launched a revolutionary top secret satellite from Vandenberg Air Force Base. Known as the KH-11 KENNEN and managed by the National Reconnaissance Office (NRO), it was the first near-real-time reconnaissance satellite capable of transmitting imagery from around the globe nearly instantaneously. Up to this time, American reconnaissance satellites used film to take their photographs, meaning that it could be days to weeks from when an image was taken to when it was seen by intelligence analysts in Washington.

Developing and testing China’s Guowang constellationby Greg Gillinger Monday, June 16, 2025
A Long March 5B launches a set of Guowang satelites. (credit: Xinhua)One of China’s top priorities is the fielding of its state sponsored Guowang Proliferated Low Earth Orbit (pLEO)
constellation. Since December 2024, China has conducted four launches carrying a combined 34 operational Guowang satellites. We know very little about the capabilities of these satellites, however China has released some information on the constellation’s architecture. According to Chinese news sources, Guowang plans to launch a total of 12,992 satellites. Of those, 6,080 will be in an extremely low orbit of 500 to 600 kilometers while the other 6,912 satellites will orbit at 1,145 kilometers.

The NASA Foundation: A method for privately funding NASA scienceby Thomas L. Matula Monday, June 16, 2025
A “NASA Foundation” modeled on the National Park Foundation could allow the public to fill gaps in the NASA budget, like for the Roman Space Telescope. (credit: NASA/Chris Gunn)Recently Jared Isaacman posted on X that, if he had become NASA administrator, he would have made up the shortfall in funding for the Nancy Grace Roman Space Telescope by personally funding its launch. It is a sentiment that is likely shared by many space advocates who wish there was an option to keep a program going by donating money to NASA to support it. This raises a question: why isn’t there a mechanism that would allow the public to contribute money to NASA? Although numerous organizations exist that are focused on lobbying Congress for a larger NASA budget while building public support for greater NASA funding, there are none that allow individuals to contribute money to fund NASA programs.

How NASA’s proposed budget cuts are felt across the Atlanticby Jeff Foust Monday, June 16, 2025
A proposal to end Orion after Artemis 3 is causing ESA and European industry to study alternative uses of the Orion service module it currently provides. (credit: NASA/ESA/ATG Medialab)The focus of the discussion about the 2026 NASA budget proposal has primarily been the effect of the request on the agency itself. The proposal, if enacted, would cancel dozens of missions and programs and lay off thousands of employees, radically reshaping NASA.

NASA’s 2026 budget in brief: Unprecedented, unstrategic, and wastefulby Casey Dreier and Jack Kiraly Monday, June 16, 2025
The Chandra X-Ray Observatory is one of dozens of missions threatened by the administration’s fiscal year 2026 budget proposal for NASA. (credit: NASA)The full details of the President’s fiscal year (FY) 2026 budget request for NASA were released in the late afternoon on Friday, May 30. To date, NASA has held no press conferences or public briefings regarding the dramatic changes included in the budget request. There have been a limited number of perfunctory briefings to congressional committees and industry stakeholders, apparently with little detail beyond what has already been released publicly.

Commercializing India’s SSLV rocketby Ajey Lele Monday, June 23, 2025
India’s Small Satellite Launch Vehicle lifts off on its inaugural, but unsuccessful, first launch in 2022. (credit: ISRO)Since its inception in the early 1970s, the Indian Space Research Organisation (ISRO) has recognized that, for any independent space agency aspiring to develop indigenous capabilities in rocket launching and satellite building, the most critical area of investment is the launch vehicle sector. India became a spacefaring nation on July 18, 1980, when its Satellite Launch Vehicle 3 (SLV-3) successfully placed the Rohini satellite into orbit. Since then, India has designed and developed various categories of launch vehicles to place satellites into different orbits. In recent years, India developed the Small Satellite Launch Vehicle (SSLV), and very recently, ISRO identified an agency for the technology transfer of this vehicle. This marks an important step toward India realizing its vision of space commercialization.

Strategies for lunar developmentby Jeff Foust Monday, June 23, 2025
How should lunar infrastructure be established, and what would it be used for? (credit: ESA/P. Carril)For advocates of lunar development, these are uncertain times. NASA’s Artemis lunar exploration campaign, which had seemed like a foundation on which a sustained lunar presence for research and commercial activities, is at an inflection point as the White House proposes terminating many elements of the effort and turning them over to commercial capabilities in ways the agency has yet to define. The administration also now appears more focused on Mars (which may or may not survive Elon Musk’s departure from the administration’s good graces) with proposed major investments in Mars, potentially at the expense of a sustained presence at the Moon.

Propelling and navigating South Korea’s space ambitionsby Jennifer Hong Whetsell and Seokjin Yun Monday, June 23, 2025
South Korea’s KSLV-II, or Nuri, rocket lifts off on its third flight in 2023. (credit: KARI)As the global space economy enters a new era marked by both competition and collaboration, South Korea is emerging as a serious contender with ambitions to lead. Once constrained by Cold War-era missile restrictions and dependent on foreign partnerships, South Korea is now steadily building sovereign space capabilities as a core pillar of its national strategy. With the creation of the Korea Aerospace Administration (KASA) in 2024, Seoul is signaling a decisive shift toward integrating space into its broader goals for technological innovation, economic growth, and national security.

Assigning an identification to a satellite, revisitedby Charles Phillips Monday, June 30, 2025
Launches of multiple payloads, like this Falcon 9 rideshare mission last year, share a characteristic that links those payloads together. (credit: SpaceX)This is another article about a useful technique to analyze satellites’ orbits, a technique that should be used to avoid mistakes in tracking these satellites. I have written several articles about this technique but wanted to keep them short (see “Assigning an identification to a satellite”, The Space Review, May 20, 2024), but want to go back and add more details here.

by Michael J. Listner Monday, June 30, 2025
Taiwan is building up its space capabilities, including the upcoming FORMOSAT-8 imaging satellites. (credit: TASA)Taiwan continues to be at the crux of a geopolitical dance over its autonomy and promises by the People’s Republic of China (PRC) for reunification since the loss of its statehood.[1] The threat posed by the PRC to Taiwan takes place with the backdrop of diminishing support geopolitically as the PRC ratchets up a hybrid warfare campaign to pave the way for reunification. In the shadow of this looming threat, Taiwan seeks to bolster its autonomy politically and by augmenting its defense to deter an invasion while holding onto dwindling geopolitical support.
