This week in The Space Review…
SpaceX’s Falcon Heavy rocket successfully launched last week after years of development delays. Jeff Foust reports on the launch and what the future prospects are for the heavy-lift rocket.
Signals intelligence satellites played a role monitoring Soviet activities during a key event late in the Vietnam War. Dwayne Day describes how that took place and how it marked the changing use of intelligence satellites.
The Falcon Heavy launch creates additional scrutiny for NASA’s Space Launch System, which is still years away from a first launch and will cost far more to develop and operate. Dick Eagleson suggests it’s time to redesign the SLS to incorporate reusability and lower costs, or else it faces an eventual cancellation.
The successful test launch of the Falcon Heavy demonstrates, to some, the growing capabilities of the private sector in space compared to agencies like NASA. Mark Wessels argues that it’s time to revisit the roles, and risk acceptance, of NASA and the private sector.
The images of a sports car launched into space on the test flight of a Falcon Heavy last week attracted the attention of people around the world. Ajey Lele, though, sees the event as a demonstration of the lack of progress in spaceflight in the last half-century.
New space applications, from constellations of broadband satellites to commercial missions to the Moon and Mars, are showing promise in the industry. Jeff Foust reviews a book that offers a guide to those emerging markets, but falls short of being a useful resource.
Venture capitalists and other investors have put billions of dollars into space startups in recent years. Jeff Foust examines if that investment can continue to grow as options for exits for these investors remain limited.
Dust on Mars, and in the Martian atmosphere, could pose a serious health and safety risk for future astronauts. Joel S. Levine identifies the concerns and the research that needs to be done to better understand the risks before humans can travel to Mars.
Orbital ATK is preparing to offer a next-generation launch vehicle it is developing to the Air Force. Jeffrey L. Smith discusses the status of that vehicle and how it fits into the broader competitive environment for government launches.
Last week marked the 60th anniversary of the launch of the first American satellite, Explorer 1, which was far smaller than the large science satellites NASA operates today. However, Jeff Foust reports, NASA and others are growing increasingly interested in returning to smaller satellites to complement the science larger spacecraft can conduct.
Legal texts on space topics are either academic treatises or resources for space law practitioners. Michael Listner reviews a book that manages to bridge the two categories.
Space centers often highlight the achievements of space programs, but what responsibility do they have to discuss tragedies and other setbacks? Dwayne Day explores that issue through the lens of exhibits at the Kennedy Space Center Visitor Complex.
Last week the X Prize Foundation announced that the Google Lunar X Prize competition will come to an end in March without any team even attempting a launch. Jeff Foust examines the end of the competition and what the teams involved planned to do now that the $20 million grand prize will no longer be available.
While countries can’t claim property on the Moon or other bodies, can they offer companies exclusion zones on safety or other rationales? Cody Knipfer examines some of the concepts behind so-called “non-interference zones” and efforts in Congress to enact legislation to enable them.
Three different projects are underway to build a new generation of very large ground-based telescopes, but each faces its own set of challenges. Jeff Foust reports on the policy challenges facing the Thirty Meter Telescope and the technical challenges of the Giant Magellan Telescope.
It’s been nearly two years since scientists announced the first direct detection of gravitational waves, enough time for gravitational wave science to almost become routine. Jeff Foust reviews a book that recounts the efforts to discover such waves and their implications for the future of astronomy.
Over the weekend, Rocket Lab successfully launched its Electron small rocket for the first time, putting three cubesats into orbit. Jeff Foust reports on that milestone launch that puts the company on the vanguard of a rapidly growing part of the space industry, albeit one where the demand for such vehicles remains uncertain.
As the Falcon Heavy near its first launch, what role can the rocket play in new national policy to return to the Moon? Doug Plata argues that the Falcon Heavy is better suited than the Space Launch System for lunar missions, as part of an architecture that makes use of vehicles from other companies and public private partnerships.
Over the last several years a number of Latin American countries have built and launched satellites. W. Alejandro Sanchez provides an update to a 2012 article on the developments countries in the region are making in terms of satellites and space policy.
The US seeks to compete with other countries in space in some arenas, and cooperate in others, but how do you decide what approach to take? Takuya Wakimoto offers an analysis of the space policies of the US and other major spacefaring countries to see where the US can benefit best through cooperation.
Proposals to create an independent “Space Force” within the US military face, among other obstacles, financial challenges. Roger X. Lenard offers a forward-looking approach to the roles of a future Space Force and how they can help support its operations and commercial activities expand beyond Earth orbit.
We know that a Falcon 9 lifted off last week carrying a classified payload known only as Zuma, but what happened to Zuma, and why, remain a mystery. Jeff Foust reports on what is known, and what is speculated, about the mission, and the implications for SpaceX as it begins a big year.
Last week India launched its Polar Satellite Launch Vehicle (PSLV) for the first time since a failure in August. Ajey Lele explains that this mission did more than demonstrate that the problem that caused the failure had been corrected.
The Moon Treaty, not ratified by major spacefaring nations, has been criticized for its “common heritage of mankind” language. Vidvuds Beldavs argues that modest changes to the treaty could address those concerns while leaving in place a framework for enabling commercial extraction of resources from the Moon and asteroids.
A space policy directive signed last month directs NASA to return humans to the Moon, but how? Gerald Black argues that NASA can’t afford to do it in traditional ways, and needs to instead work in partnership with the private sector.
Spaceports are popping up around the United States and elsewhere, far outpacing the demand from commercial launch companies. Jeff Foust reviews a book that attempts to explain why that’s the case by visiting a number of existing and proposed launch sites.
President Trump signed a directive last month amending national space policy to call for a human return to the Moon. Chris Carberry and Rick Zucker argue that this need not be in conflict with plans for human missions to Mars, provided the administration is willing to back its policy with sufficient funding.
As commercial suborbital vehicles capable of carrying people prepare to enter service, those vehicles offers new opportunities for “ordinary” people to fly into space. John Putman cautions that such opportunities will require people to prepare not just physically but also psychologically.
As spacecraft become more advanced, and probe more distant parts of the solar system, communications becomes a weak link. Jeff Foust reports on how NASA is working on laser communications technologies for Earth science and planetary missions to dramatically increase data rates.
In the concluding part of her interview, Emily Carney talks with Jonathan Ward, co-author of a new book on the Columbia accident investigation, on the recovery effort and comparisons with other NASA human spaceflight accidents.

After years of delays, two companies are edging closer to flights of commercial suborbital vehicles carrying people. Jeff Foust reports on those companies’ progress and the effect they will have on the suborbital research field.

A year ago, a classified US satellite reentered over the South Pacific without any advance warning or other notice by US government agencies. Charles Phillips discusses why, for safety’s sake, the government should provide a warning of such reentries without disclosing the satellite’s mission.
A new book due out this month chronicles the investigation into the Columbia shuttle accident 15 years ago. In the first of a two-part interview, Emily Carney talks with co-author Jonathan Ward about the development of the book and what he learned about the tragedy.
