Lunar exploration ground sites will enhance the Near Space Network's communications services
Tuesday, 23 July 2024 16:44
NASA's LEGS can do more than help Earthlings move about the planet. Three Lunar Exploration Ground Sites, or LEGS, will enhance the Near Space Network's communications services and support of NASA's Artemis campaign.
NASA's Space Communications and Navigation (SCaN) program maintains the agency's two primary communications networks—the Deep Space Network and the Near Space Network, which enable satellites in space to send data back to Earth for investigation and discovery.
Using antennas around the globe, these networks capture signals from satellites, collecting data and enabling navigation engineers to track the mission. For the first Artemis mission, these networks worked in tandem to support the mission as it completed its 25-day journey around the moon.
Opinion: If we want to settle on other planets, we'll have to use genome editing to alter human DNA
Tuesday, 23 July 2024 15:28
When considering human settlements on the moon, Mars and further afield, much attention is given to the travel times, food and radiation risk. We'll undoubtedly face a harsh environment in deep space and some thinkers have been pointing to genome editing as a way to ensure that humans can tolerate the severe conditions as they venture further into the solar system.
In January, I was fortunate to attend a much-anticipated debate between astronomer royal Lord Martin Rees and Mars exploration advocate Dr. Robert Zubrin. The event at the British Interplanetary Society took on the topic of whether the exploration of Mars should be human or robotic.
In a recent book called The End of Astronauts, Lord Rees and co-author Donald Goldsmith outline the benefits of exploration of the solar system using robotic spacecraft and vehicles, without the expense and risk of sending humans along for the ride.
Moon dust could contaminate lunar explorers' water supply
Tuesday, 23 July 2024 14:27
Water purification is a big business on Earth. Companies offer everything from desalination to providing just the right pH level for drinking water. But on the moon, there won't be a similar technical infrastructure to support the astronauts attempting to make a permanent base there. And there's one particular material that will make water purification even harder—moon dust.
We've reported plenty of times about the health problems caused by the lunar regolith, so it seems apparent that you don't want to drink it. Even more so, the abrasive dust can cause issues with seals, such as those used in electrolyzers to create rocket fuel out of in-situ water resources. It can even adversely affect water purification equipment itself.
Unfortunately, this contamination is inevitable. Lunar dust is far too adhesive and electrostatically charged to be kept completely separate from the machinery that would recycle or purify the water.
Expiring medications could pose challenge on long space missions

Medications used by astronauts on the International Space Station might not be good enough for a three-year journey to Mars. A new study led by Duke Health shows that over half of the medicines stocked in space—staples such as pain relievers, antibiotics, allergy medicines, and sleep aids—would expire before astronauts could return to Earth.
Astronauts could end up relying on ineffective or even harmful drugs, according to the study appearing July 23 in npj Microgravity.
"It doesn't necessarily mean the medicines won't work, but in the same way you shouldn't take expired medications you have lying around at home, space exploration agencies will need to plan on expired medications being less effective," said senior study author Daniel Buckland, M.D., Ph.D., an assistant professor of emergency medicine at Duke University School of Medicine and an aerospace medicine researcher.
Expired medications can lose their strength by a little—or a lot. The actual stability and potency of medications in space compared to Earth remain largely unknown. The harsh space environment, including radiation, could reduce the effectiveness of medications.

Chief of Space Operations advocates refocus on integrated defense at Global Air, Space Chiefs' Conference
Monday, 22 July 2024 13:36
During a trip to the United Kingdom, U.S. Space Force Chief of Space Operations Gen. Chance Saltzman appeared at the Global Air and Space Chiefs' Conference, delivering a keynote address to a crowd of global leaders, industry partners and academics in the air and space defense industry, July 17.
Titled "Toward Integrated Defense in Space," Saltzman's address began with a discussion on the NASA Sounding Rocket Launches, Studies Heating of Sun's Active Regions

Investigators at NASA's Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the Sun's corona grows so much hotter than the visible surface of Earth's parent star.

Monday, 22 July 2024 13:36
The exploration of consciousness in artificial systems can take various approaches. One approach focuses on the likelihood of current AI systems achieving consciousness and identifying the requirements needed to enhance this likelihood. Another approach, as taken by researcher Wanja Wiese, examines which types of AI systems are unlikely to become conscious and aims to prevent the unintended crea
