This week in The Space Review…
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.
The search for “technosignatures” of civilizations beyond Earth is winning new support, including positive language in a House NASA bill. Jeff Foust reviews a book that argues that it’s time for a new strategy for such search efforts based on the proliferation of new approaches and the failures of past efforts.
Russian historians recently uncovered a Soviet report from the 1970s that studied whether the Space Shuttle could be used as a bomber to attack Moscow. Bart Hendrickx and Dwayne Day study that report in more detail to better understand its logic, and its flaws.
Outside the United States, the country with the most vibrant commercial space startup industry may be China, with dozens of firms established in just the last few years pursuing launch vehicles, satellites, and more. Jeff Foust examines a report that offered detailed insights on the size and growth potential of Chinese entrepreneurial space.
Iran is preparing to attempt another satellite launch in the coming days, amid tensions about its nuclear programs. Henk Smid discusses the history of both Iran’s ballistic missile and space launch vehicle programs to better understand if the latter helps the former.
NASA’s Mission Control in Houston has developed a reputation for rigorous decision making needed for the safety and success of human spaceflight. Jeff Foust reviews a book by a former director describing how the management of the organization that runs Mission Control needed to be overhauled.
At the end of this month, NASA will decomission the Spitzer Space Telescope, the second of the original four Great Observatories to go dark. Jeff Foust reports on what astronomers think NASA should do to continue the promise of the Great Observatories to enable space-based observations over a wide range of wavelengths.
Today is the 90th birthday of Apollo 11 astronaut Buzz Aldrin. Eric Hedman reflects on Aldrin’s influence on his own life.

Jeff Foust reports these missions are providing lessons, good and bad, on how to manage flagship missions as astronomers weigh what should come next.
Plans by SpaceX and other companies to deploy megaconstellations of satellites have alarmed astronomers, who worry that such satellites could interfere with their observations. Arwen Rimmer argues that such satellites should be a concern to anyone who looks up into the night sky, not just professional astronomers.
China’s Long March 5 rocket successfully returned to flight in late December after a failure nearly two and a half years ago. Namrata Goswami explains that this shows that that country’s lunar ambitions, including eventual human missions to the Moon, need to be taken seriously.
Existing treaties may be ill-equipped to deal with the surge in both government and commercial missions to the Moon. Dennis O’Brien discusses what changes a recent white paper recommended to one agreement regarding the registration of such missions.
In 2019, NASA accelerated its plans to return to the Moon under a program now called Artemis. Jeff Foust reports that NASA will have to overcome a number of challenges, financial and otherwise, to stay on track in 2020.
In the 1960s, NASA and the National Reconnaissance Office quietly cooperated on an imaging system developed for reconnaissance satellites that NASA sought to use to support lunar missions. Dwayne Day describes how the very different nature of the agencies, and changes in the program, made it difficult for them to work together.
Boeing’s CST-100 Starliner test flight last month was cut short because a problem linked to a timing error in the spacecraft. Wayne Eleazer explains it’s not the first mission where a timing error caused problems.
While there has been a surge of spaceports proposed in recent years, the supply of such facilities doesn’t match the demand for launch services. Roger Handberg notes this is similar to another wave of proposed spaceports two decades ago.
In the decades after landing on the Moon, Neil Armstrong received tens of thousands of letters, from political and business leaders to ordinary people. Jeff Foust reviews a book that offers a selection from that archive, and some of Armstrong’s responses.
NASA entered 2019 hopeful that it would be able to start launching American astronauts on American rockets from American soil before year’s end. Jeff Foust reports that, as the year comes to an end, commercial crew faces continued challenges, highlighted by the problems on the recent test flight of Boeing’s CST-100 Starliner.
During the 1970s, the Soviet Union feared that the Space Shuttle could be used as a bomber to drop nuclear weapons on Moscow with little warning. Dwayne Day describes how a Russian researcher has turned up documents explaining how Soviet leaders came to that conclusion.
NASA recently announced that the Kuiper Belt object that New Horizons flew by at the beginning of the year would be formally known as Arrokoth, after provisionally, and controversially, being called Ultima Thule. Andrew Rader discusses how this is only one of many challenges facing the naming of celestial bodies and features on them.
The first American to fly a rocket-powered aircraft was William Swan in 1931. Mark Wade examines the mysterious life of Swan, including a disappearance at the site of a present-day launch site.
