With OneWeb’s bankruptcy filing, astronomers may have one less satellite constellation to worry about disrupting their observations. But, as Jeff Foust reports, they are still working with SpaceX to find ways to mitigate the effects of the Starlink satellites.
Besides being one of the most trusted people in America in the 1960s, Walter Cronkite was also a space buff who closely followed, and covered, the Apollo program. Dwayne Day finds an interview from decades later where Cronkite discussed how critical his coverage of the program was.
A new series of missions may be bound for Venus in the coming decade by NASA and other space agencies. Arwen Rimmer talked with planetary scientist and astrobiologist David Grinspoon on why renewed studies of Venus can help us not just understand our nearest planetary neighbor but also worlds around other stars.
One obstacle to a permanent human settlement on Mars, in the minds of many, is how such a settlement could be economically viable. John Strickland argues that a business case isn’t essential to a Mars settlement, at least during its formative phase.
Most histories of the Apollo program are written from an American perspective, but the program, especially the Apollo 11 landing, was a worldwide phenomenon. Jeff Foust reviews a book where people around the world discuss their memories of the first Moon landing and how it inspired them.
Much of the space industry, like the broader economy and society, has ground to a halt in the last few weeks because of the coronavirus pandemic. Jeff Foust reports on what has shut down and what is continuing more or less as usual in spaceflight, at least for now.
The DARPA Launch Challenge ended earlier this month without a winner when the last remaining company scrubbed their final launch attempt. Todd Master, manager of the competition, explains how the DARPA Launch Challenge evolved and offers lessons learned for the future of responsive launch.
Robert Seamans was deputy administrator of NASA during the Apollo 1 fire in 1967, and was one of the officials who testified at a Senate hearing about it months later. Dwayne Day finds new insights about Seamans and his relationship with administrator James Webb in an interview from more than 20 years ago.
Magnificent isolation: what we can learn from astronauts about social distancing and sheltering in space
Calls for self-quarantine and “social distancing” in response to the pandemic have some people seeking to learn from the experience of explorers. Deana Weibel examines what astronauts, including the late Al Worden, can teach us about handling isolation in extreme circumstances.
Glen Swanson offers a more through examination of a recent book about the creation of the “golden records” that flew on the Voyager spacecraft with photos and sounds representing Earth.
Sen. Walter Mondale’s questioning of NASA in a hearing after the Apollo 1 fire led to his portrayal as a critic of the agency opposed to Apollo. Dwayne Day unearths an interview with Mondale that offers a different perspective on Mondale’s views about the program.
Last week the European Space Agency announced it was postponing the launch of its ExoMars rover mission from 2020 to 2022 because of technical problems. Jeff Foust reports on that delay and potential risks to other Mars missions scheduled for launch this year because of matters beyond their control.
Efforts to create treaties or other international agreements to keep space from becoming weaponized have failed to gain traction. Ajey Lele says an international organization, separate from any treaty regime, might be able to make progress on space security.
Later this year NASA astronauts will fly to the International Space Station on commercial crew vehicles. Roger Handberg discusses how that is reopening debates about the role NASA should play in overseeing the safety of such spacecraft.
The DARPA Launch Challenge ended last week without a winner as the sole remaining team failed to launch within the competition window. Jeff Foust reports on how Astra was less than a minute away from launching when it had to scrub its launch, and what it means for the long-running effort to demonstrate responsive launch.
The special relationship between the United States and United Kingdom extended to access to reconnaissance satellite imagery during the Cold War. Aaron Bateman examines how that influenced policy in the UK regarding arms control and anti-satellite weapons in the 1980s.
One of the shows on the Apple TV+ streaming service is For All Mankind, which examines an alternative history based on the Soviets landing a man on the Moon before the US. Dwayne Day discusses the strengths and weaknesses of that alternative history that many space advocates have desired.
One of the best known aspects of the Voyager missions is the “golden record” included on the two spacecraft with photos and audio from Earth. Jeff Foust reviews a book that recounts how that album came together.
It’s common today to see mentions of a new “space race” involving the United States and China. Dwayne Day argues that term doesn’t make sense, since there’s no agreement on where they are racing, when, or why.
OneWeb and SpaceX are shifting into high gear to deploy their broadband satellite constellations, with more systems proposed and in development. Jeff Foust reports on what industry expects think are the prospects for success for these systems, given the business and other challenges they face.
A Venus orbiter called EnVision is among the finalists for the next medium-class science mission by the European Space Agency. Arwen Rimmer explains why scientists, meeting at a conference in Paris last month, believe the mission is vital for ESA to pursue.
In early 20th century astrophysics, one of the most important discoveries was that stars were made primarily of hydrogen and helium, yet few people know the astronomer who made that discovery. Jeff Foust reviews a book about the life and career of Cecilia Payne-Gaposchkin, who overcame major obstacles on the path to that achievement.
The US government released updated orbital debris mitigation guidelines in December, the first update to those guidelines in nearly two decades. Brian Weeden explains why the few changes in the new guidelines are disappointing and a sign that the US may no longer be a global leader in dealing with orbital debris.
NASA awarded Axiom Space an agreement in January that gives the company the opportunity to attach a commercial module to an International Space Station docking port. Jeff Foust reports that, despite this milestone, there’s still uncertainty about the business plans of such companies and NASA’s ability to provide financial support for them.
Spacecraft engineers are studying a variety of approaches for deorbiting satellites at the end of their lives to minimize the growth of orbital debris. Rebecca Hill discusses one concept being studied that adapts solar sail technologies to bring down satellites.
The Hubble Space Telescope, approaching its 30th anniversary, has a legacy enabled by the ability to repair and upgrade the observatory over the years. Jeff Foust reviews a book by a NASA astronaut who played a key role ensuring the telescope could be repaired by later shuttle missions.
Last month, two defunct satellites missed colliding with each other by only meters, an event widely seen as a wakeup call about the dangers of orbital debris and the need to take action. Jeff Foust reports that while that incident might have raised awareness, it won’t necessarily translate into near-term action.
In a recent commentary, Louis Friedman argued against NASA racing back to the moon, saying its energies are better placed for going to Mars. Four authors note that Friedman once backed the concept for an “International Lunar Decade,” a concept that is still worth pursuing today.
Advances in satellite and launch technologies are often touted as opening space for new and expanded business opportunities. Dylan Taylor argues that such technologies also democratize space, making it available to more people around the world.
Six decades ago, a group of women later known as the “Mercury 13” took medical tests that demonstrated that they were just as able to handle the rigors of spaceflight as NASA’s male Mercury 7 astronauts. Jeff Foust reviews a book that profiles two of the women at the heart of that effort, which similar goals but different plans to achieve them.
One software error truncated an uncrewed test flight of Boeing’s CST-100 Starliner spacecraft in December, but last week a safety panel revealed there was a second problem that could have caused a “catastrophic” failure. Jeff Foust reports on that new problem and its implications for Boeing’s commercial crew vehicle.
Despite the long-term promise of extracting water ice and other resources from the moon, such efforts, done commercially, face the daunting challenge of raising funding. Blake Ahadi suggests some alternative approaches, drawn in part from similar issues faced in terrestrial mining, to help fund lunar resource extraction.
The establishment of a Space Force in the US has raised questions about international law provisions that prohibit some military activities in space. Bharatt Goel notes that while the militarization of space is hardly new, the Space Force could heighten debates about the roles of militaries in space.
Millennials are a growing part of the space community, but are their views of what they want to do in space, and why and how, that different from previous generations? Jeff Foust reviews a book that offers insights based on interviews with 100 millennials in the field.
As the White House prepares to release a budget proposal that will include a cost estimate for NASA’s Artemis program, the House Science Committee took up a NASA authorization bill that could make significant changes to it. Jeff Foust reports on the debate about the bill and its importance versus the upcoming budget and appropriations process.
A report by two Soviet academicians in the 1970s, which argued that the Space Shuttle that the US was developing could be used as a bomber, is widely thought to have spurred development of the Buran shuttle. Bart Hendrickx and Dwayne A. Day examine that claim and find that the report likely only reinforced an earlier decision regarding Buran.
Launch vehicle developers have for decades struggled to come up with approaches to enable frequent and cost-effective access to space using spaceplanes. Francis Castanos advocates for an alternative approach.

Advancing the jurisdiction of the US federal court system to address disputes between private space actors
The emerging commercial space industry brings with it potential for new disputes that could be difficult for current legal systems to handle. Michael Listner offers a proposal for how US federal courts could deal with cases involving companies from different countries.
As the 50th anniversary of Apollo 11 winds down, so do the books about that mission and the early Space Age. Jeff Foust reviews a book that offers a concise and thoughtful history of that era of spaceflight.
As NASA and the nation prepares to celebrate the 50th anniversary of Apollo 11, the agency got caught up last week in issues involving its effort to return humans to the Moon. Jeff Foust reports on the shakeup that led NASA to reassign two top officials in its human spaceflight program.
Science and religion can often seem diametrically opposed to each other. Deana Weibel describes how NASA’s long-running relationship with the Vatican Observatory, one dating back to Apollo, can show how the two can work together instead.
Last week, Dwayne Day explained how a tall tale he created about a mythical Soviet program to send chimpanzees to the Moon took on a life of its own on the Internet. This week, the story itself.
While there’s an avalanche of new books about Apollo and the Moon, many others written years or decades ago are still excellent guides to the Moon. Ken Murphy offers his list of books about the Moon, and not necessarily Apollo, that have stood the test of time.
The story of Apollo is usually told through the lens of its most famous figures, from astronauts to politicians. Jeff Foust reviews a book that instead examines Apollo from the perspective of those working behind the scenes.
NASA launched an Orion spacecraft last week, and it returned to Earth minutes later, just like the agency planned. Jeff Foust reports on the test of Orion’s abort system that took the spacecraft a step closer to flying people.
Some in the US Air Force had plans in the 1960s for military space stations beyond the original Manned Orbiting Laboratory concept. John Charles examines how some of those proposals were depicted in art.
No, the Soviets didn’t land a chimpanzee on the Moon, but it can be fun to craft such a tale as a clever inside joke. Dwayne Day describes what happens when that story takes on a life of its own on the Internet.
In the decades since Apollo 11, hundreds of books have been published about the mission and the overall race to the Moon. Thomas Frieling looks at some of the books that have stood the test of time, and a couple that haven’t.
Commemorations of the Apollo 11 50th anniversary are also appearing on television in the form of a number of documentaries. Jeff Foust reviews a companion book to one of the more ambitious documentaries that focuses more on personalities and policies than science and technology.
Top Secret DAMON: the classified reconnaissance payload planned for the fourth space shuttle mission
The NRO built a reconnaissance payload for the Space Shuttle that would have been on STS-4, but the program was cancelled before it flew. Dwayne Day provides new insights on that program and why it was grounded.
The “megaconstellations” of communications satellites under development by Amazon, OneWeb, SpaceX, and others come two decades after previous efforts to develop networks of communications satellites in low Earth orbit ran into financial difficulties. Stephen J. Garber and James A. Vedda compare the two generations to see if history will repeat itself.
During planning for the Apollo landings, NASA turned to the NRO to develop a camera system based on reconnaissance satellites for mapping the Moon, including investigating any landing accidents. Dwayne Day examines what is known about the proposed system based on recently declassified information.
It took tens of thousands of engineers, technicians, and others to get astronauts to the surface of the Moon 50 years ago. Jeff Foust describes how a few astronomers and other scientists also contributed, in some cases literally guiding the way.
The first four space policy directives from the Trump Administration have dealt with everything from returning humans to the Moon to establishing a Space Force. Peter Garretson argues the next should deal with making use of the energy resources of space.
As its 50th anniversary approaches, the Apollo 11 mission is being retold in a variety of media. Jeff Foust reviews two graphic novels that recount the mission, and the history of the Space Age, in a mix of text and illustrations.
