This week in The Space Review…
At long last, a 1960s-era GAMBIT reconnaissance satellite is on display at the National Air and Space Museum. Dwayne Day recaps the history of the program and describes the efforts it took to get the spacecraft displayed at the famous museum.
Construction of a telescope on a Hawaiian mountain has stopped because of protests from those who believe it would desecrate what some native Hawaiians consider a sacred place. Jeff Foust reports on the controversy and what some astronomers are doing to try and find a resolution acceptable to all.
This month, India will carry out its biggest commercial launch to date, of five satellites weighing nearly 1,500 kilograms. Narayan Prasad argues that, despite this milestone, India needs to do more to promote commercial space ventures in the country.
To some, the end of the shuttle program represented an end of an era of American human spaceflight, or even an end to American human spaceflight itself. Jeff Foust reviews a book by a writer who attended the final shuttle launches in an attempt to understand the shuttle’s end and its implications.
On Sunday, SpaceX suffered the first failure of its Falcon 9 rocket in 19 launches, losing a Dragon cargo spacecraft bound for the ISS. Jeff Foust reports on what’s known about the failure and its implications for the company, the space station, and broader space policy.
Developing a coherent, sustainable space policy in the US is made challenging by changing administrations and a Congress often stuck in partisan gridlock. Clark Cohen describes how an alternative approach to congressional representation could end that gridlock and help space policy.
In just over two weeks, NASA’s New Horizons spacecraft will speed past Pluto in the first spacecraft reconnaissance of that distant world. Dwayne Day describes an ambitious mission concept from the 1980s to send a nuclear-powered orbiter, with landers, to Pluto.
The coverup, and later investigations, into Nazi scientists who found refuge in the United States after World War II remains controversial. Michael Neufeld reviews a book that examines the roles Nazi scientists and engineers played in America after the war, including two involved in the space program.
There is growing interest in developing constellations of smallsats for a variety of missions, with new concepts appearing regularly. Jeff Foust reports on some of the challenges these ventures face both in launching those satellites and dealing with orbital debris risks.
The issue of the role deterrence plays in protecting space assets has been the subject of debate in military policy circles. Roger G. Harrison and Deron R. Jackson respond to a recent essay here to defend their concept of a multi-layered approach to space deterrence.
Many space advocates lament that the US did not act upon the plans for long-term space exploration proposed as Apollo achieved its lunar landing goal. Alastair Browne argues that there’s little need to regret that path not taken, since the nation would not have traveled far down it.
Astronauts comprise an elite group, and it’s hard to think of any of them as ordinary. Jeff Foust reviews a book by a self-described “ordinary” astronaut whose details about life as an astronaut, in space and on Earth, are far from ordinary.
In a month, NASA’s New Horizons spacecraft will fly past the dwarf planet Pluto, the first spacecraft to visit this distant world. Dwayne Day ponders the effect the spacecraft flyby will have not just on science, but culture and policy as well.
While NASA has argued it needs full funding for its commercial crew program to keep it on schedule for first flights in 2017, House and Senate appropriations bills cut the request by hundreds of millions of dollars. Jeff Foust reports on the disconnect and its implications for the agency and the two companies under contract.
In the event that humans detect a signal from an extraterrestrial intelligence, or the more unlikely event of a physical encounter with them, how would the legal system be prepared to deal with repercussions? Babak Shakouri Hassanabadi discusses how existing treaties and interpretations of international law might apply in such scenarios.
Many of the German engineers who were at the core of America’s early space program came over after World War II in an effort called Operation Paperclip. Michael Neufeld reviews a book that offers a dramatic, but flawed, history of that program.
NASA is clear about its long-term goal of human spaceflight—sending humans to Mars—but has been vague about the next steps beyond low Earth orbit to achieve that goal. Jeff Foust reports how NASA, working with companies and potential international partners, is starting to look at a series of missions in cislunar space in the 2020s as those next steps.
America’s lead in military space capabilities is threatened by a number of internal and external factors. Tom Taverney discusses what those factors are and what the US needs to do to overcome them.
Estimates of the cost of a NASA Mars mission for six astronauts are north of $100 billion. Sam Dinkin wonders how this cost estimate would change if reusable rocket launches cost what SpaceX predicts they will.
Fifty years ago, NASA was racing to the Moon while the civil rights movement was unfolding. Jeff Foust reviews a book that examines the complex ways that the two efforts interacted as NASA sought to bring more African Americans into its workforce.
The most recent International Space Development Conference, like many of its predecessors, held sessions on space based solar power. Yet, as Dwayne Day notes, there’s been little progress in the field in recent years, and no sign that this long-term dream of space advocates is close to becoming reality.
Last week NASA announced the instruments it plans to fly on a future mission to Europa, while the House of Representatives is expected to approve a bill this week that would sharply increase funding for the mission. Jeff Foust reports, though, that as proponents attempt to make the mission more ambitious, they could also make it a target in future budget debates.
A recent essay argued for going to the Moon now because of the considerable challenges of sending humans to Mars. David Whitfield critiques the article and argues that there are ways to accomplish human missions to both worlds.
This week marks the 50th anniversary of Gemini 4 and the first American spacewalk, a milestone that will likely be recalled with the same, small set of images. Jeff Foust reviews a book that recalls missions like that using images not previously widely released.
Concepts of interplanetary spacecraft often face challenges with power, propulsion, radiation shielding, and more. Brian McConnell offers a concept for a “spacecoach” spacecraft that overcomes many of those obstacles by making use of water and solar electric propulsion in unique ways.
Both the House and Senate are considering legislation to support the US commercial launch industry, including extending key provisions of current law. Jeff Foust reports on those efforts, including the contrast between the partisan debates in the House and the bipartisan effort in the Senate.
As commercial ventures in outer space grow, so do issues like the protection of trade secrets such companies may obtain from their space activities. Kamil Muzyka explores the issue of trade secrets and offers one approach to protecting them.
India is making progress, albeit slowly, on the next generation of its GSLV launch vehicle designed to end the country’s dependence on foreign launchers. Debalina Ghoshal examines the state of the vehicle’s development.
Black holes are widely accepted today both in astrophysics and in popular culture, even though half a century ago they seemed inconceivable to many scientists. Jeff Foust reviews a book that offers a concise history of our understanding of black holes, and how they redeemed general relativity.
NASA says it has a plan for human missions to Mars in the 2030s. Jeff Foust reports that some, though, are pressing NASA for more details about those plans and coming up with alternative concepts that they believe could accelerate those crewed missions to the Red Planet.
Getting humans to live beyond Earth in a sustainable manner is a long-term effort with many steps involved. Derek Webber proposes that NASA focus on two initial steps, supporting key technologies that can enable eventual human space settlement.
Brazil is considering terminating its agreement with Ukraine to launch Cyclone 4 rockets from its spaceport, dealing another setback to that country’s space access plans. Ajey Lele suggests that Brazil partner with other nations, including India, to jointly develop launchers.
It’s been more than 40 years since Gene Cernan was the last human to walk on the Moon. Shane Hannon talks with the director and producer of a documentary about Cernan’s life.
He is one of the major figures in the space industry today, but Elon Musk remains something of an enigma to people who are puzzled by his way of doing business and his passion for Mars. Jeff Foust reviews a new biography that covers Musk’s life and his work at SpaceX.
Once on the cutting edge of commercial spaceflight, suborbital vehicles have been overshadowed in recent years, in part due to their development delays. Jeff Foust reports that, finally, some of these vehicles are entering, or about to enter, flight tests.
A recent study found that cosmic radiation astronauts would be exposed to on Mars expeditions could cause brain damage, resulting in dementia or other disorders. Robert Zubrin takes issue with the study’s methodology and argues the radiation risk to humans is far less serious than what the study concludes.
Colin Burgess is a prolific author currently working on a series of book about the Mercury program. Dwayne Day interviews Burgess to discuss how he got involved in writing about the subject and what space history books are in his future plans.
Space exploration has the ability to inspire students to pursue careers in science and engineering, as demonstrated by Apollo. However, Blake Ortner warns that inspiration could be suffocated by plans that take far too long to carry out.
To some, we appear to be on the verge of a new era of spaceflight, but even if that’s true, what does that mean for our future in space? Jeff Foust reviews a book that attempts to address that issue, but whose flaws may leave readers unconvinced.
Fifty years ago this week, the Soviets declared a mysterious Mars-bound mission called Zond 2 a failure. Andrew LePage examines the history of the program to uncover what Zond 2’s mission really was.
Six months ago, the commercial spaceflight industry suffered a double dose of accidents, just days apart. Jeff Foust reports on the progress made in the investigations of the Antares and SpaceShipTwo failures, and plans for them to resume flights.
On Wednesday, SpaceX is scheduled to perform a pad abort test of the crewed version of its Dragon spacecraft it is developing as part of NASA’s commercial crew program. Rick Boozer compares the capabilities of Dragon with NASA’s own Orion spacecraft.
India’s space program has achieved a number of major milestones in recent years, but still is a secondary player in the global space field. Narayan Prasad and Prateep Basu argue that India needs to encourage entrepreneurial space activities and better delineate civil and military space applications to further grow its space industry and be more competitive in the global market.
NASA’s program of robotic Mars missions has produced tremendous successes and embarrassing failures in the last quarter-century. Jeff Foust reviews a book that offers a comprehensive history of that era of Mars exploration, examining the challenges that even the most successful missions had to overcome.
NASA celebrated last week the 25th anniversary of the launch of the Hubble Space Telescope, looking back on the scientific accomplishments of that famous space telescope. Jeff Foust reports on what the next 25 years in space astronomy might look like beyond Hubble.
There remains interest in carrying out human missions to the surface of the Moon, even though that is not an official goal of the Obama Administration. Anthony Young discusses how a commercial model for lunar transportation, based on the COTS and commercial crew programs, might be the most cost-effective, and perhaps the only, way to carry out such missions.
Recent proposals have offered missions architectures to get humans to the vicinity of Mars, if not necessarily on the surface of the planet, by some time in the 2030s. Joe Webster argues that to maintain public support, those timelines need to be accelerated with a modest amount of additional funding.
Many in the space community like to debate the merits of two heavy-lift vehicles under development, NASA’s SLS and SpaceX’s Falcon Heavy. Dale Skran offers a tale of the tape of the two heavyweights, comparing their planned capabilities and costs.
Last week marked the fifth anniversary of President Obama’s speech at the Kennedy Space Center, outlining his vision for the future of NASA’s space exploration efforts. Jeff Foust examines the progress NASA has made in various aspects of that vision, and the controversies that linger to this day.
Recent studies and recommendations by advisory groups have raised interest in a mission to Phobos as a precursor to a Mars mission, perhaps in place of NASA’s Asteroid Redirect Mission. Louis Friedman notes that such interest in Phobos missions is not new, and may also not be that effective for long-term human Mars exploration.
Social events like Yuri’s Night are increasingly popular, but are they an effective way to increase awareness of and interest in space? Alan Steinberg goes over the results of a survey that explored that issue.
In recent weeks, plans for human Mars missions have been criticized for both their technical and financial feasibility. John Strickland argues that these critiques don’t hold up when Mars architectures are revised to take advantage of reusable launch systems.
Space can be a dangerous place, and knowing the various risks and their odds can be vital for space exploration. Jeff Foust reviews a book that tries to do just that, but falls far short of the mark.
The United States’ policy towards dealing with the potential use of weapons in space is one of deterrence. Christopher Stone argues that this strategy may be a flawed application of the concept of deterrence.
NASA adopted the “flexible path” approach to spaceflight as a more economical way to carry out human space exploration than a human return to the Moon. Roger Handberg described how this flexible path may be bending right back to the Moon.
Last week, Blue Origin announced a milestone in the development of an engine intended for its suborbital vehicle. Jeff Foust reports on the company’s plans for testing that suborbital vehicle, as well as its orbital vehicle and engine plans.
Can an international cooperation in lunar exploration open up commercial opportunities and expand the space economy? Vidvuds Beldavs describes how an “International Lunar Decade” could do just that.
While NASA’s civil space activities are supposed to be separate from the Pentagon’s military space work, the two have interacted, sometimes in collaboration and sometimes not. Jeff Foust reviews a book that offers a detailed history of those relationships, from the shuttle to Earth observation.
Recent studies have indicated you can either do human Mars missions in the 2030s with more money that NASA current receives, or wait until mid-century on NASA’s current budget. Jeff Foust reports on a new study that finds, although with few details, that humans to Mars by the 2030s can fit within NASA’s current budgets.
The Moon, and the moons of Mars, have previously been proposed as key steps towards getting humans on Mars. Al Anzaldua and Dave Dunlop propose an approach that involves those bodies, as well as Martian volcanoes, as key steps in a sustainable long-term exploration strategy.
Singer Sarah Brightman is in the midst of training for a September flight to the International Space Station as a space tourist. Anthony Young discusses her interest in spaceflight and her plans for her ten-day trip to space.
Launches can suffer from any number of conventional, well-known problems. But, as Wayne Eleazer recalls, there are plenty of, well, weird incidents involving launches and preparations for them.
