A Concentrated Beam of Particles and Photons Could Push Us to Proxima Centauri

Getting to Proxima Centauri b will take a lot of new technologies, but there are increasingly exciting reasons to do so. Both public and private efforts have started seriously looking at ways to make it happen, but so far, there has been one significant roadblock to the journey – propulsion. To solve that problem, Christopher Limbach, now a professor at the University of Michigan, received a grant from NASA’s Institute for Advanced Concepts (NIAC) to work on a novel type of beamed propulsion that utilizes both a particle beam and a laser to overcome that technology’s biggest weakness.

Growing Habitats and Furniture in Space Out of Mushrooms

Over the years we have often seen astronauts gently and deftly moving structures into place with their bare hands. Thinks are easy to move in space but getting them there is slightly more tricky and costly. A new piece of research has explored the possibility of growing structures in space based on food substrates. NASA has now awarded a grant to a proposal to investigate further growing structures using fungal mycelial composites, that’s mushrooms to you and I.

Slingshotting Around the Sun Would Make a Spacecraft the Faster Ever

NASA is very interested in developing a propulsion method to allow spacecraft to go faster. We’ve reported several times on different ideas to support that goal, and most of the more successful have utilized the Sun’s gravity well, typically by slingshotting around it, as is commonly done with Jupiter currently. But, there are still significant hurdles when doing so, not the least of which is the energy radiating from the Sun simply vaporizing anything that gets close enough to utilize a gravity assist. That’s the problem a project supported by NASA’s Institute for Advanced Concepts (NIAC) and run by Jason Benkoski, now of Lawrence Livermore National Laboratory, is trying to solve.

A New Way to Survive the Harsh Lunar Night

The Moon is a tough place to survive, and not just for humans. The wild temperature extremes between day and night make it extremely difficult to build reliable machinery that will continue to operate. But an engineering team from Nagoya University in Japan have developed an energy-efficient new way to control Loop Heat Pipes (LHP) to safely cool lunar rovers. This will extend their lifespan, keeping them running for extended lunar exploration missions.

Warp Drives Could Generate Gravitational Waves

Will future humans use warp drives to explore the cosmos? We’re in no position to eliminate the possibility. But if our distant descendants ever do, it won’t involve dilithium crystals, and Scottish accents will have evaporated into history by then.

NASA has a New Database to Predict Meteoroid Hazards for Spaceflight

There are plenty of problems that spacecraft designers have to consider. Getting smacked in the sensitive parts by a rock is just one of them, but it is a very important one. A micrometeoroid hitting the wrong part of the spacecraft could jeopardize an entire mission, and the years of work it took to get to the point where the mission was actually in space in the first place. But even if the engineers who design spacecraft know about this risk, how is it best to avoid them? A new programming library from research at NASA could help.

Lighting Up the Moon’s Permanently Shadowed Craters

The Moon’s polar regions are home to permanently shadowed craters. In those craters is ancient ice, and establishing a presence on the Moon means those water ice deposits are a valuable resource. Astronauts will likely use solar energy to work in these craters and harvest water, but the Sun never shines there.

What’s the solution? According to one team of researchers, a solar collector perched on the crater’s rim.

NASA Takes Six Advanced Tech Concepts to Phase II

From a lunar railway to a space telescope with a liquid lens, the 2024 NIAC Phase Two awardees are developing some fascinating concepts. This collage of artist concepts highlights the novel approaches proposed by the Phase Two awardees for possible future missions.

It’s that time again. NIAC (NASA Innovative Advanced Concepts) has announced six concepts that will receive funding and proceed to the second phase of development. This is always an interesting look at the technologies and missions that could come to fruition in the future.

Psyche is Still Sending Data Home at Broadband Speeds

NASA’s Psyche spacecraft is shown in a clean room at the Astrotech Space Operations facility near the agency’s Kennedy Space Center in Florida on Dec. 8, 2022. DSOC’s gold-capped flight laser transceiver can be seen, near center, attached to the spacecraft. NASA/Ben Smegelsky

When I heard about this I felt an amused twinge of envy. Over the last year I have been using an unimpressive 4G broadband service and at best get 20 Mbps, NASA’s Psyche mission has STILL been getting 23 Mbps at 225 million km away! It’s all thanks to the prototype optical transmission system employed on the probe. It means it can get up to 100 times more data transmission rate than usual radio.

What’s the Most Effective Way to Explore our Nearest Stars?

It was 1903 that the Wright brothers made the first successful self-propelled flight. Launching themselves to history, they set the foundations for transatlantic flights, supersonic flight and perhaps even the exploration of the Solar System. Now we are on the precipice of travel among the stars but among the many ideas and theories, what is the ultimate and most effective way to explore our nearest stellar neighbours? After all, there are 10,000 stars within a region of 110 light years from Earth so there are plenty to choose from.
