There’s growing interest in using CubeSats for a variety of scientific, commercial, and other applications. However, Jeff Foust reports that CubeSat developers are grappling with the issue of reliability of such satellites, which suffer higher failure rates than larger spacecraft.
Some in the Middle East are concerned that Iran, now free of sanctions linked to nuclear weapons development, might become more aggressive in the region. Michael Listner argues that this should provide an impetus for other nations there to develop comprehensive, coherent space policies.
Europe has been a major partner on the International Space Station program, even though it’s the last to formally endorse an extension of station operations through 2024. Jeff Foust reviews a book that recaps the first decade of European expeditions to the ISS, with many details but few deeper insights about the overall effort.
As the number of smallsats under development grows, so does the number of options for getting those satellites into space. Jeff Foust reports on efforts to both develop dedicated small launch vehicles as well as make greater use of rideshares on larger rockets.
New technologies are allowing high altitude balloons to perform applications once reserved for satellites. Alan Stern describes the new capabilities such balloons offer and how they are augment or replace space capabilities.
In these turbulent times, can space exploration help unite society? Zach Miller argues that lessons from the Apollo era, combined with the growth of commercial space ventures, show what is possible.
Gus Grissom was the second American in space, but most people’s perceptions of him are shaped by the negative portrayal of him in The Right Stuff and his death on Apollo 1. Jeff Foust reviews a book that attempts to offer a more complete biography of the man and his contributions to NASA.
There is an ongoing debate about whether humans should first return to the Moon before setting out on expeditions to Mars. Chris Carberry and Rick Zucker argue that human lunar missions should stand or fall on their own merits, rather than be justified as Mars precursors.
Germany will hold the presidency for the G20 nations in 2017. In an open letter to German Chancellor Angela Merkel, the International Lunar Decade Working Group suggests she include space development, including a “Moon Village,” on the agenda of issues the G20 will take up in 2017.
Regardless of who wins the election, the next administration is likely to take a close look at NASA’s major exploration programs. Jeff Foust reports that while NASA says those efforts are making good progress, GAO reports found potential cost and schedule issues with them.
An article a space website reprinted from a Russian news service appears to have extensively borrowed, without attribution, from another article. Dwayne Day examines this latest case of space plagiarism and why this is a serious problem.

If you could get the presidential candidates to answer one question about their prospective space policies, what should it be? Jeff Foust argues that it might to get them to explain why they believe NASA should have a human spaceflight program.
Forty-five years ago this week, the Apollo 15 astronauts held a brief, private ceremony to memorialize the astronauts and cosmonauts who had died in the last decade. Jeff Foust reviews a book that examines the lives of those men and the circumstances of their deaths.
NASA hopes that, by the time it’s ready to retire the International Space Station in the 2020s, one or commercial space stations will be ready to support researchers and others using the ISS today. Jeff Foust reports that one step towards a commercial station may be a commercial module on the ISS.
In the second and final part of his examination of literature set in cislunar space, Ken Murphy reviews novels from the 1990s to the present, and looks at some overall trends in literature.
A recent study suggests that the Moon has played a bigger role than previously thought in making the Earth habitable. Peter Kokh says this, plus the Moon’s role in our future, should influence what we consider to be “Earth-like” worlds.
The concept of mission control is one that has been an essential part of spaceflight since the beginning of the Space Age, but not all mission controls are alike. Jeff Foust reviews a book that examines differences in mission controls based on country and types of missions.
Scott Kelly returned to Earth earlier this year after spending nearly a year on the International Space Station. Jeff Foust reports on what he said his experience there was like, and how a study involving his twin brother may provide new insights into the effects of long-duration spaceflight.
One of the fundamental questions of human spaceflight is why humans should go beyond Earth at all. Eric Hedman examines human spaceflight from the perspective of the survival imperative, and what research needs to be done to ensure that humans can, in fact, survive on other worlds.
Stories about activities in cislunar space have been staples of science fiction for decades. In the first of a two-part review, Ken Murphy examines some of the cislunar science-fiction novels in the first few decades of the Space Age.

Jeff Foust reviews a book that offers a new, and comprehensive, look at the development of the shuttle and the challenges faced leading up to, and during, that first flight.
Legislation passed by the US Congress last year appeared to clear the way for space mining ventures. Jeff Foust reports that there are still policy issues these and other companies have to overcome both at a national and an international level.
In his final installment examining a wide-ranging space policy bill, Michael Listner examines the sections of the bill dealing with commercial space law and regulations.
For decades, Pluto was largely ignored in science fiction, with too little known about the distant world to stimulate the imaginations of authors. Dwayne Day wonders, with New Horizons now revealing Pluto to be a far more dynamic place than expected, whether it will become fodder for more works of fiction.
Many still assume that human presence and activity in space will always have government in the lead. Dick Eagleson makes the case that this view ignores fundamental limits on government involvement in space activities and sketches out how human expansion into space must be increasingly driven by private entrepreneurship if it is to happen at all.
In the last few decades, astronomers have discovered that the universe’s galaxies trace out intricate patterns, rather than be randomly distributed. Jeff Foust reviews a book by an astrophysicist who helped understand why those structures, in some cases spanning more than a billion light-years, came to be.
The International Space Station has demonstrated how the US and Russia can cooperate in space even when terrestrial relations are strained. Ajey Lele argues that this can serve as a model for cooperation in space between China and India.
