Space agencies will play a vital role in the developing space economy, especially in the beginning. But what will the part of the biggest of all space agencies be when considering how space resources, especially those on the Moon, are accessed? NASA has a plan for that as it does for so many other things – and this article will dig into a slideshow that describes that plan in detail.

Where does the solar wind come from? That’s a question solar physicists have wanted an answer to for decades. Now, the Parker Solar Probe is showing them exactly where this stream of particles exits our star on a journey out through interplanetary space.

In astronomy, elements other than hydrogen and helium are called metals. While that might make your high-school chemistry teacher cringe, it makes sense for astronomers. The two lightest elements were the first to appear in the universe. They are the atomic remnants of the big bang and make up more than 99% of atoms in the universe. All the other elements, from carbon to iron to gold, were created through astrophysical processes. Things like nuclear fusion in stellar cores, supernova explosions, and collisions of white dwarfs and neutron stars.

By 2030, multiple space agencies will have sent astronauts to the Moon for the first time since the Apollo Program ended over 50 years ago. These programs will create lasting infrastructure, like the Lunar Gateway, Artemis Base Camp, Moon Village, and the International Lunar Research Station (ILRS). In the ensuing decade, the first crewed missions to Mars are expected to occur, culminating with the creation of the first human outposts on another planet. Commercial ventures also want to establish habitats in Low Earth Orbit (LEO), enabling everything from asteroid mining to space tourism.

Despite decades of warnings and international climate agreements, global carbon emissions are still rising. Carbon emissions seem like an unstoppable juggernaut as energy-hungry humans keep breeding and pursuing more affluent lifestyles. Reducing emissions won’t be enough to confront the climate crisis; we need additional solutions.

Hawking radiation is one of the most famous physical processes in astronomy. Through Hawking radiation, the mass, and energy of a black hole escape over time. It’s a brilliant theory, and it means that black holes have a finite lifetime. If Hawking radiation is true. Because as famous as it is, Hawking radiation is unproven. The theory is not even theoretically proven.

The 8-meter Gemini North telescope has been brought back online after seven months of repairs and refurbishment of its primary mirror. The timing couldn’t have been better, as the telescope was able to capture the brand-new supernova in the famous Pinwheel Galaxy. The bright supernova was first discovered on May 19th, and telescopes worldwide have been revealing its secrets.

Our Sun continues to demonstrate its awesome power in a breathtaking collection of recent images taken by the U.S. National Science Foundation’s (NSF’s) Daniel Inouye Solar Telescope, aka Inouye Solar Telescope, which is the world’s largest and most powerful ground-based solar telescope. These images, taken by one of Inouye’s first-generation instruments, the Visible-Broadband Imager (VBI), show our Sun in incredible, up-close detail.

Star formation is one of the oldest processes in the Universe. In the Milky Way and most other galaxies, it unfolds in cold, dark creches of gas and dust. Astronomers study sites of star formation to understand the process. Even though they know much about it, some aspects remain mysterious. That’s particularly true for the “Nessie Nebula” in the constellation Vulpecula. An international team led by astronomer James Jackson studies the nebula and its embedded star-birth regions. They found that it experienced a domino effect called “triggered star formation.”

California residents will be glad to know their reservoirs are nearly full again after years of drought. New satellite photos show the levels of Shasta Lake, California’s largest reservoir, going from 31% capacity last November to nearly 100% in May 2023. The reservoir was filled with heavy rains and a significant mountain snowpack that melted into the nearby rivers.

NASA believes in getting the public excited about space, and they’re carrying on this tradition by recently announcing that space fans from around the world can travel to Jupiter with the Europa Clipper mission. Though, not literally, but by adding their names to a microchip for the “Message in a Bottle” campaign that will also contain “In Praise of Mystery: A Poem for Europa”, which is an original poem by U.S. Poet Laureate Ada Limón.

Things tend to move from the simple to the complex when you’re trying to understand something new. This is the situation exoplanet scientists find themselves in when it comes to the term ‘habitable.’ When they were discovering the first tranche of exoplanets, the term was useful. It basically meant that the planet could have liquid water on its surface.

We can gaze out into regions in our neighbourhood of the Milky Way and find orgies of star birth. The closest region is in the Orion nebula, where astronomers have identified more than 700 young stars. They range from only 100,000 years—mere infancy for a star—to over a million years.

When a mission to Mars reaches 20 years of service, that’s definitely reason to celebrate. ESA’s Mars Express celebrated by airing the first-ever livestream of images, sent directly from the Visual Monitoring Camera (VMC) on board the spacecraft. For an hour, it sent back images from the Red Planet in as close to real-time as the speed of light would allow.

NASA’s next colossal rocket, the Space Launch System (SLS), recently had its first successful flight back in November after years of development. Much of that development was done by aerospace contractors like Northrop Grumman and Boeing, so it is a good bet that engineers at those companies want the SLS to be seen as a success. One measure of its success will be how many missions it manages to help launch successfully – the more missions, the better. To help plan out some of those missions, a pair of Boeing engineers wrote a paper describing an outline of a sample return mission to Phobos and Deimos. And, of course, it would be launched by the SLS.

The Mars Express orbiter, the European Space Agency’s (ESA) first interplanetary mission, entered orbit around Mars on June 2nd, 2003. Since then, the probe has mapped the Martian surface using its High-Resolution Stereo Camera (HRSC), an instrument built by the German Aerospace Center (DLR) with commercial partners. In honor of the mission’s 20th anniversary, a celebration occurred last Friday (June 2nd) at the ESA’s European Space Operations Center (ESOC) in Darmstadt, Germany.

Several million years ago, the core of our galaxy experienced a powerful event. It blew out a huge bi-lobed bubble that blasted through the interstellar medium in two directions. Whatever it was, it released huge amounts of energy from the central supermassive black hole, Sagittarius A* (Sgr A* for short).

When astronomers used the JWST to look at a galaxy more than 12 billion light years away, they were also looking back in time. And when they found organic molecules in that distant galaxy, they found them in the early Universe.

New technologies utilizing material found in space are constantly popping up, sometimes from smaller companies and sometimes from larger ones. Back in 2020, one of the largest companies of them all announced a technology that could have significant implications for the future lunar exploration missions planned over the next ten years. The European aerospace giant Airbus developed the Regolith to OXYgen and Metals Conversion (ROXY) system. 

Human technology is crossing another threshold. Tractor beams have been common in science fiction for decades. Now a team of researchers is working on a real-life tractor beam that could help us with our burgeoning space debris problem.

Solar power is the fastest-growing form of renewable energy and currently accounts for 3.6% of global electricity production today. This makes it the third largest source of the renewable energy market, followed by hydroelectric power and wind. These three methods are expected to grow exponentially in the coming decades, reaching 40% by 2035 and 45% by 2050. Altogether, renewables are expected to account for 90% of the energy market by mid-century, with solar accounting for roughly half. However, several technical challenges and issues need to be overcome for this transition to occur.
