A subtle symphony of ripples in spacetimeby Chris Impey Monday, July 3, 2023
Gravitational waves create ripples in spacetime that alter the precise timing of pulsars that are then detected by astronomers. (credit: Aurore Simonnet for the NANOGrav Collaboration)Astronomers use dead stars to measure gravitational waves produced by ancient black holesAn international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration, called NANOGrav, was able to measure a low-frequency hum from a chorus of ripples of spacetime.

What does the People’s Republic of China’s space program mean for Great Britain and the West?by Jack Sharpe, Fotios Moustakis, Markos Trichas, and Damian Terrill Monday, July 3, 2023
Growing Chinese military and civil space capabilities create challenges and opportunities for the West. (credit: Xinhua)Despite its relative infancy operating in space, the People’s Republic of China (PRC) has become increasingly successful in launching satellites and has become the only country to successfully launch a space vehicle to the far side of the Moon (Jones, 2021). These achievements have consolidated the PRC’s reputation as a spacefaring nation. Speaking in 2021, President Xi Jinping stated “to explore the vast cosmos, develop the space industry and build China into a space power is our eternal dream” (China’s Space Programme: A 2021 Perspective, 2022).

Regulating a maturing commercial spaceflight industryby Jeff Foust Monday, July 3, 2023
VSS Unity glides overhead on its way back to Spaceport America during the Galactic 01 flight June 29. (credit: J. Foust)For a change, the significance of the flight was bigger than the spectacle.
Compared to nearly two years ago, when Virgin Galactic founder Richard Branson got his long-awaited suborbital spaceflight just days before rival Jeff Bezos (see “The suborbital spaceflight race isn’t over”, The Space Review, July 11, 2021), the atmosphere at Spaceport America last week was relatively subdued. There were no huge crowds of media or invited gusts, no celebrities or musical performances. Even Branson himself appeared to be absent, at least not making any public appearances at the spaceport.

Spinning towards the future: crisis response from spaceby Dwayne A. Day Monday, July 3, 2023
SPIN SCAN was a satellite studied from 1967-1970 and intended to provide imagery to the ground within 24 hours. The satellite would spin edge toward the ground while imaging, and then edge-on while recharging its batteries. SPIN SCAN was rejected in spring 1971, and it was not until late 1976 and the advent of the KH-11 KENNEN satellite that the United States acquired a near-real-time reconnaissance capability. (credit: NRO)In the early morning of June 5, 1967, hundreds of Israeli aircraft took off from their bases and headed out over the Mediterranean and the Red Sea before turning toward Egypt. They attacked multiple Egyptian airbases, and soon more than 300 Egyptian aircraft were smoking wrecks with their airfields torn to shreds. Shortly thereafter, the Six-Day War was over.

Reality is underrated: Fox’s “Stars on Mars” takes offby Dwayne A. Day Monday, July 10, 2023
The summer space-themed reality show “Stars on Mars” sends its participants on missions inspired by the 2015 movie The Martian. The show is more clever and watchable than you would expect. It airs Monday nights on Fox and streams on Hulu. (credit: Fox Television)I was wrong.
Five weeks ago, I wrote about the Fox space-themed “reality” TV show “Stars on Mars” and predicted that it would be awful. I based that assessment on the commercials and the advertising, and my biases against reality television, most of which is—to borrow a trope from one of the more notorious examples—garbage. I expected to hate-watch the show.

Don’t jeopardize national security in the name of competitionby Jonathan Ward Monday, July 10, 2023
While the Space force is looking to provide opportunities for new launch providers, like Blue Origin and its New Glenn rocket, a Senate proposal to accelerate that process could create national security risks. (credit: Blue Origin)The establishment of the US Space Force marked a significant milestone in America's commitment to maintaining its dominance in space. As the guardians of the final frontier, it is imperative that the Space Force maintains the highest standards when it comes to the launch of mission-critical satellites. The Senate Armed Services Committee’s recent proposed changes to the launch services procurement process, however, risk undermining the Space Force’s ability to deploy our most crucial space-based defense assets.

A crisis and an opportunity for European space accessby Jeff Foust Monday, July 10, 2023
An Ariane 5 lifts off for the 117th and final time July 5 from French Guiana. (credit: ESA-CNES-Arianespace/Optique video du CSG/P. Piron)Two launches this month illustrated the current state of European access to space.
Last Wednesday, an Ariane 5 lifted off from Kourou, French Guiana. It was, in many respects, a typical Ariane 5 launch, carrying two communications satellites bound for geostationary orbit. One, Heinrich-Hertz-Satellit, was built by German company OHB for the German government to test advanced communications technologies. The other, Syracuse 4B, was built by a consortium of Airbus Defence and Space and Thales Alenia Space to provide communications for the French military.

Could a 500-year-old treaty hold the key to peace in space?by Daniel Duchaine Monday, July 17, 2023
As more countries pursue exploration of the Moon and Mars, it creates increasing opportunities for geopolitical conflict in space. (credit: CNSA)Space is changing again. Much has been made about the “Second Space Age” where launch costs are cheaper and more countries have access. This is all correct, of course and we are right to think about it. We are not there yet, but the discourse around space is changing from merely a support system for Earth to providing value by itself.

The Chandrayaan-3 mission to the Moon is underwayby Ajey Lele Monday, July 17, 2023
An LVM3 rocket successfully launched India’s Chandrayaan-3 lunar lander mission July 14. (credit: ISRO)On July 14, the Indian Space Research Organisation (ISRO) started its latest mission to the Moon. For India, this is an important mission because an earlier mission Chandrayaan-2, launched four years earlier, was only a partial success. That mission had two elements: an orbiter and a lander and rover system. ISRO was successful with the orbiter, but the lander crashed attemping a soft landing in September 2019.

For Mars Sample Return, more serious repercussionsby Jeff Foust Monday, July 17, 2023
A conceptual illustration of NASA’s current plans to implement the Mars Sample Return program in cooperation with ESA. NASA is facing new pressure to get the costs of the program down. (credit: NASA)An event in Washington last Thursday evening marked the first anniversary of the release of the first science images from the James Webb Space Telescope, a declaration that the nearly $10 billion telescope was ready to deliver on the promises made over its decades of development (see “The transformation of JWST”, The Space Review, July 18, 2022.)

Smashing satellites as part of the Delta 180 Strategic Defense Initiative missionby Dwayne A. Day Monday, July 17, 2023
Declassified photo of the Delta 180 spacecraft launched in September 1986 as part of the Strategic Defense Initiative. This was the first in-space test for SDI and it was successful, possibly bolstering the resolve of President Reagan one month before the Reykjavik Summit. The mission was classified until after it was successful, and was clearly intended to impact public perception of the prospects of the “Star Wars” anti-ballistic missile program. (credit: SDIO)In September 1986, two American satellites smashed into each other high in the skies over the Pacific Ocean, creating a spectacular shower of sparks and streaks, and making a powerful statement. This was no accident, but a deliberate test as part of the Strategic Defense Initiative (SDI)—nicknamed “Star Wars” by opponents and the media—and one of the most impressive examples of rapid spacecraft development of the Cold War.

Access to Venusby John Strickland Monday, July 24, 2023
Images of the surface of Venus taken from the Venera 13 mission. (credit: NASA)Venus is the opposite of Mars in regard to terraforming. In fact, you would practically have to terraform Venus before you could land humans on it. It has a planetary surface almost as large as the Earth’s. However, removing the 90 atmospheres of carbon dioxide, even at the very high volatile transfer rates proposed for terraforming Mars, would probably take many millennia and an enormous amount of energy. A low energy, faster alternative would be to build a 15,000-kilometer-wide sunshade for Venus which would cause the carbon dioxide atmosphere to collapse into a liquid carbon dioxide ocean or frozen dry ice layer, at Antarctic-like temperatures.

Another technique to identify “unknown” satellitesby Charles Phillips Monday, July 24, 2023
The three CERES satellites, seen here before launch, are among those whose orbital elements are not included in public catalogs. (credit: Airbus)A long-time interest of mine has been to look at satellite catalogs and see what is in them—and what is not.
The (default world official) satellite catalog is maintained by the US Space Force. They assign numbers to each known satellite and they assign the “COSPAR” designator (see below for a little more about that), which is one way that the international community labels satellites. They normally do an adequate job; the satellite catalog is at Space Track and many organizations and people use it.

The value of public interest in spaceflightby Jeff Foust Monday, July 24, 2023
Despite the success of, and attention surrounding, the Artemis 1 mission, only a small percentage of those polled thought returning humans to the Moon was a top priority for NASA. (credit: NASA/Bill Ingalls)The space community has long had an interest, bordering on an obsession, with public opinion of space initiatives. That interest can be healthy and necessary: publicly funded space projects, like those of NASA, do require some degree of public support to continue. But it also at times can become a mania: if only more people knew what NASA was doing and supported it, advocates argue, NASA could get the budget increases it needs to carry out those ambitions.

https://www.netflix.com/pl/title/81473680It’s been more than a year since the release of the first science images from the James Webb Space Telescope, demonstrating that the $10 billion spacecraft has met, if not exceeded, the expectations of astronomers who waited decades to use it. The 12 months that followed have only reinforced those conclusions as the telescope has trained its mirror on the distance universe and worlds in our solar system, generating a cascade of discoveries with only a few minor technical glitches.

Is China’s rise in space over? Indexing space power for the next space ageby Daniel Duchaine Monday, July 31, 2023
China has emerged as a major space power in part because of its rapidly increasing launch rate, but will the country cotinue to rise at the expense of other nations? (credit: Xinhua)We will soon enter an age where space is not merely a domain to support Earth but another region, with regional great power competition. As space becomes a true region, international relations tools will become increasingly more enlightening. In this paper, I seek to introduce a way to track “Space Power” by creating an index showing which countries are great powers in space, which countries hold the greatest share of this power in space, and tracking this over time and into the future. Understanding these dynamics is vital for understanding the most likely sources and periods of conflict and cooperation.

Should the loss of the Titan submersible impact space tourism?by Dale Skran Monday, July 31, 2023
The loss of a submersible with five people on board has drawn parallels to commercial spaceflight and the risks people flying on such vehicles face. (credit: Blue Origin)With the recent loss of the Titan submersible on a voyage to visit the Titanic, voices have been raised suggesting that the nascent space tourism industry requires immediate regulation. Before jumping on this bandwagon, let’s take a minute to compare the space tourist “industry” with the usage of submersibles and submarines for tourist voyages.

The highs and lows of extreme tourism: The Titan accident and commercial expeditions to space and the deep seaby Deana L. Weibel Monday, July 31, 2023
The loss of the Titan submersible with five people on board has triggered discussions about the differences between deep-sea and space travel, and between tourism and research. (credit: OceanGate)On June 18, 2023, the OceanGate submersible Titan imploded in the midst of an expedition to view the remains of the Titanic, the famous ocean liner that sank after striking an iceberg on April 15, 1912. Between the Titan’s demise and the discovery of the submersible’s debris on June 22, speculation spread far and wide about the fate of the five participants. They were OceanGate CEO Stockton Rush, Titanic expert Paul-Henri Nargeolet, Action Aviation chair and recent Blue Origin astronaut Hamish Harding, Pakistani business executive and SETI Institute trustee Shahzada Dawood, and Dawood’s 19-year-old son, university student Suleman Dawood. Conversations proliferated across news stations and social media about whether the five might be stuck in the submersible with a dwindling oxygen supply or whether some or all had of the passengers had already died.

Nuclear space gets hotby Jeff Foust Monday, July 31, 2023
Lockheed Martin and BWXT will develop a nuclear thermal propulsion demonstration spacecraft for NASA/DARPA’s DRACO program. (credit: Lockheed Martin)Many in the space community had long recognized the value that nuclear power provides, particularly for missions beyond Earth orbit. It can generate electricity regardless of the distance from, or visibility of, the Sun, useful for both missions to the distance solar system or the Moon and its two-week lunar night. Nuclear propulsion, either thermal or electric, offers much higher efficiencies than chemical systems, and nuclear thermal propulsion (NTP) in particular can significantly shorten travel times for crewed Mars missions.
