Methods for building lunar landing pads may involve microwaving moon soil

Establishing a moon base will be critical for the U.S. in the new space race and building safe and cost-effective landing pads for spacecraft to touch down there will be key.

These pads will have to stop and particles from sandblasting everything around them at more than 10,000 miles per hour as a rocket takes off or lands since there is no air to slow the rocket plume down.

However, how to build these landing pads is not so clear, as hauling materials and heavy equipment more than 230,000 miles into space quickly becomes cost prohibitive.

Pulsar Fusion — In orbit assembly of nuclear fusion rocket

The animation describes the concept of launching a nuclear fusion reactor into orbit in sections for final assembly in space. The concept uses live footage of Pulsar’s existing hall effect plasma thrusters (HET) and hybrid rocket engines tested at RAF Westcott in March 2022. Pulsar is also developing LOX / Methane rocket motors to support this concept.

A “forest bubble” on Mars? Scientist proposes ambitious plan for sending wildlife to Mars

The ambitious proposal could help realize Elon Musk’s vision of SpaceX’s Starship as a “futuristic Noah’s Ark”.

A botanist and ecologist has crafted a detailed proposal for a flourishing green space on the barren, desolate surface of Mars, a report from CNET

Dreaming of an Earth-like environment on Mars.

The “extraterrestrial nature reserve”, or ETNR, would take the form of a greenhouse-like “forest bubble” designed to create an Earth-like ecosystem on the red planet. It would allow humans to experience a slice of home on Mars while also acting as a sustainable source of food and raw materials for early inhabitants.

Incredible Orion footage shows what astronauts will experience during NASA’s Artemis II mission

Humans will launch aboard NASA’s Orion spacecraft for Artemis II, which is currently slated for a 2024 launch.

Incredible new footage from NASA’s moon mission Artemis I looks straight out of a Christopher Nolan sci-fi epic.

Lockheed Martin, the company that built the Orion spacecraft, shared the launch footage on its Twitter page, allowing viewers to imagine what it will be like for astronauts aboard NASA’s crewed Artemis II mission.

The inside of NASA’s Orion spacecraft glows with a pink hue as the Launch Abort System (LAS) tower is jettisoned from the uncrewed capsule, which is being fired to orbit by the Space Launch System (SLS).

Laser Tattoo

Year 2008 o.o!

That is so fantastically ridiculous and dangerous… not that the laser is terribly dangerous; more for the incredibly fast print head. the video reminds me of “Starship Troopers”, i love it. it’s probably not deep, i wonder if they heal up after a few months.

Make a small one, get it FDA approved! it’s the wave of the future!

How to Build A Time Machine — Paul Davies

Time travel makes great science fiction, but can it really be done? Travel into the future is already a reality, but visiting the past is a much tougher proposition, and may require fantastic resources such as a wormhole in space. Nevertheless, if going back in time is allowed, even in principle, then what about all those paradoxes that make time travel stories so intriguing?

Paul Davies is a physicist, cosmologist and astrobiologist at Arizona State University, where he is Director of the Beyond Center for Fundamental Concepts in Science. He is the author of many books, including “How to Build a Time Machine” and, most recently, “The Eerie Silence: are we alone in the universe?”
