Moon and Mars advocates find peace
by Jeff Foust Monday, September 14, 2020

For decades, it seems, space exploration advocates have done battle over the long-term goals of human spaceflight, even as humans remained stuck in low Earth orbit. Some have argued for a return to the Moon, both for its own sake as well as a proving ground for missions beyond. Others, though, have pushed for going to Mars, often as soon as possible, fearing that a lunar return could be a costly, lengthy detour. (...)

Two historic observatories were in the news recently, not because of any new discoveries they made but instead due to threats to their existence. Last month, a wildfire in the early days of California’s horrific fire season approached Lick Observatory, on a mountaintop near San Jose. Last week, another fire encroached on Mount Wilson Observatory near Los Angeles, at one point coming within a couple hundred meters of its major telescopes. Fortunately, in both cases firefighters were able to halt the fires, with only minor damage at each observatory. (...)

Review: Orphans in Space
by Glen E. Swanson Monday, September 21, 2020


Orphans in Space is a two-DVD set with an eclectic collection of little-known space-related films.

Orphans in Space: Forgotten Films from the Final Frontier
DVD
2012, The Orphans Film Project

In early April, while doing research for an article (see “‘Space, the final frontier’: Star Trek and the national space rhetoric of Eisenhower, Kennedy and NASA”, The Space Review, April 20, 2020), I interviewed Megan Prelinger. During that interview, she mentioned that both she and her husband Rick helped assemble a collection of space-themed films that appeared in a DVD set called Orphans in Space: Forgotten Films from the Final Frontier.

Venus: science and politics
by Ajey Lele Monday, September 21, 2020


An image of the surface of Venus taken by the Soviet Union’s Venera 13 mission.

For many years, the major focus for space exploration has been Mars and the Moon. Of course, the scientific community has been involved in missions elsewhere in the solar system, but the agendas for major space agencies have been dominated by the missions to the Moon and Mars. Now, there exists a possibility that another world could push its way into those agendas.

The discovery

Venus is known as the hottest planet in the solar system, with surface temperatures as high as 470°C. In fact, Venus is even hotter than Mercury because Venus thick atmosphere filled with carbon dioxide, generating a runaway greenhouse effect. Venus is sometimes called the sister planet of the Earth, since it is very similar to the Earth in terms of size and mass. However, the problem is that the temperature and atmosphere of Venus makes it entirely different than the Earth. (...)

Why the detection of phosphine in the clouds of Venus is a big deal
by Paul K. Byrne Monday, September 21, 2020


The discovery of phosphine in the atmosphere of Venus could be a sign of life, as well as a sign of new life for exploration of thew planet. (credit: European Space Organization/M. Kornmesser & NASA/JPL/Caltech)

[This article was originally published by The Conversation, and is reprinted under a Creative Commons license.]

On September 14, a new planet was added to the list of potentially habitable worlds in the Solar System: Venus.

Phosphine, a toxic gas made up of one phosphorus and three hydrogen atoms (PH3), commonly produced by organic life forms but otherwise difficult to make on rocky planets, was discovered in the middle layer of the atmosphere of Venus. This raises the tantalizing possibility that something is alive on our planetary neighbor. With this discovery, Venus joins the exalted ranks of Mars and the icy moons Enceladus and Europa among planetary bodies where life may once have existed, or perhaps might even still does today.

Where will Artemis 3 land? And when?
by Jeff Foust Monday, September 21, 2020


Comments last week suggested the Artemis 3 lunar landing might not take place near the lunar south pole, but NASA has since reiterated it still plans to go to the south pole. (credit: NASA)

NASA’s Artemis program faces many challenges to overcome to achieve its goal of landing humans on the Moon in 2024. There are the myriad technical problems that have already occurred, and will likely continue to crop up in the coming years as NASA completes development of the Space Launch System, Orion, one or more human lunar landers, and the lunar Gateway. Funding remains a challenge, as evidenced by a House bill that provides NASA with less than a fifth the funding it sought for the Human Landing System (HLS) program (see “Irregular disorder and the NASA budget”, The Space Review, July 27, 2020). And, there’s the possibility that a change of administrations next year will lead to a slowdown, or even abandonment, of the entire program. (...)

Photons and phosphine
by Jeff Foust Monday, September 28, 2020


Rocket Lab’s Photon satellite bus will be used to support the launch of NASA’s CAPSTONE mission to the Moon next year. (credit: NASA)

On August 31, a Rocket Lab Electron rocket lifted off from the company’s launch pad in New Zealand, placing a radar imaging satellite for startup Capella Space into orbit. The launch represented the return to flight of the Electron, which failed in its previous launch less than two months earlier (see “It’s (small) rocket science, after all”, The Space Review, July 6, 2020). An investigation tracked down the cause of the failure to an “anomalous electrical connection” in the rocket’s second stage that had evaded the company’s acceptance testing processes prior to launch.

Battle of the Titans (part 1)
by Wayne Eleazer Monday, September 28, 2020


What would become the Titan IV faced challenges both before and after the Air Force selected the design for development. (credit: Lockheed Martin)

As has been described in various articles in The Space Review (see “When ‘about time’ equals ‘too late’”, October 11, 2005; “The engine problem”, August 3, 2015; “About those scrapped Atlas ICBMs”, July 6, 2010), the Space Shuttle was developed to be the sole US launch vehicle that would be supported by the US Government. All US government payloads eventually would fly on nothing but the shuttle and that meant American commercial payloads would also. All rocket engine development except that related to the shuttle was stopped in the 1970s and most rocket engine production ended as well. (...)

Reality bites
by Dwayne A. Day Monday, September 28, 2020


The website for the planned “Space Hero” reality TV show has a countdown clock but little else about the show that would send the winner to the ISS. (credit: spacehero.me)

Two weeks ago, the Hollywood publication Deadline reported an exclusive that sounded a lot like déjà vu all over again:

“Space Hero Inc., a U.S.-based production company founded by Thomas Reemer and Deborah Sass and led by former News Corp Europe chief Marty Pompadur, has secured a seat on a 2023 mission to the International Space Station. It will go to a contestant chosen through an unscripted show titled Space Hero. Produced by Ben Silverman and Howard Owens’ Propagate, the series will launch a global search for everyday people from any background who share a deep love for space exploration. They will be vying for the biggest prize ever awarded on TV.” (...)

India’s Mars orbiter completes six years at the red planet, but where is the science?
by Jatan Mehta Monday, September 28, 2020


India’s Mangalyaan spacecraft arrived at Mars six years ago, but the scientific output of the mission has been a disappointment. (credit: ISRO)

September 24 marked six years since ISRO’s Mars Orbiter Mission, or Mangalyaan, spacecraft entered Mars orbit, making India the first Asian country to do so. What is even more impressive is that Mangalyaan was the country’s first interplanetary mission. Combined with the cost effectiveness for which it is lauded, Mangalyaan is often hailed as India’s most successful space mission. But is it? (...)

Review: Space Is Open for Business
by Jeff Foust Monday, October 5, 2020


Space Is Open for Business: The Industry That Can Transform Humanity
by Robert C. Jacobson
Robert Jacobson, 2020
paperback, 418 pp., illus.
ISBN 978-1-7342051-0-7
US$32.99
https://www.amazon.com/exec/obidos/ASIN/1734205105/spaceviews

Despite the economic upheavals in the last year caused by the coronavirus pandemic, interest in space continues largely unabated (see “Commercial space, and space commercialization, weather the pandemic”, The Space Review, this issue). CNBC reported over the weekend on a recent analysis by Bank of America, which projected the global space economy would more than triple over the next decade, to $1.4 trillion in 2030. While the analysis was simplistic—Bank of America simply assumed the average annual growth rate of the last two years, more than 10%, would continue for the next ten—it exemplifies the bullishness the investment community has shown in space in recent years.

Why addressing the environmental crisis should be the space industry’s top priority
by Loïs Miraux Monday, October 5, 2020

How can we give meaning to space missions in the context of a global environmental crisis? World Space Week 2020 (October 4–10) and its theme “Satellites Improve Life” will remind us of the numerous benefits that space-based assets bring on Earth. However, as climate change has been largely recognized as an existential threat in the 21st century, some space activities, such as space exploration or space tourism, raise important questions. Some projects continue to promise technological solutions to environmental issues in outer space. They won’t help. The environment should be space industry’s top priority. (...)

Commercial space, and space commercialization, weather the pandemic

The Northrop Grumman Cygnus spacecraft that launched Friday night from Wallops Island, Virginia, bound for the International Space Station, carried a diverse array of cargo. There were science and technology demonstration payloads, ranging from testing cancer treatments to growing radishes in microgravity (yes, scientists said at a pre-launch briefing, the astronauts will be able to eat the radishes.) There were also some nitrogen gas bottles for the station’s air supply as the crew worked to trace the source of a small air leak, now thought to be in the Zvezda module. And there was the Universal Waste Management System, a next-generation space toilet that will be tested on the ISS before it’s used on the Orion spacecraft. (“When the astronauts have to go, we want to allow them to boldly go,” said one member of the team that developed it.) (...)

Battle of the Titans (part 2)

It was a matter of national policy that the Space Shuttle would be the only new US launch system, but not everyone in the US Air Force agreed with that philosophy. The Complementary Expendable Launch Vehicle (CELV) procurement that began in 1984 and became the Titan IV program addressed back up launches for three very important Air Force payloads, all to be launched from Cape Canaveral (see “Battle of the Titans (part 1)”, The Space Review, September 28, 2020). Soon after CELV got underway in 1984, some Air Force officers began thinking about the problem of alternative launch capabilities for payloads using polar orbits launched from Vandenberg Air Force Base.
