Two Space Stories In 2024 Will Determine The Future Of Humanity

Posted by in categories: biotech/medical, robotics/AI, space travel

A long-awaited space mission in the coming year could herald the start of a new era where so many science fiction dreams finally begin to cement themselves as science fact. But first we must pass a critical test of our own making that pits our technological expansion into orbit against the sun itself.

It’s not that difficult to predict what science stories we’ll be talking about over the next year: artificial intelligence, climate change and advances in biotechnology will remain front of mind. But there’s a pair of happenings just beyond our planet that I’ll be watching closely, because they amount to tests of a sort that could determine the trajectory of our species.

Euclid: Gate to the dark

Posted by in categories: cosmology, space travel

ESA’s Euclid mission is on a quest to unveil the nature of two elusive ‘dark’ entities. As the renowned theoretical physicist Stephen Hawking remarked in 2013, “The missing link in cosmology is the nature of dark matter and dark energy”

During the last 70 years, scientists have made enormous progress in understanding the very initial phases of the Universe and its evolution to the present day. Thanks to advances in observations and theoretical modelling, a clear picture has emerged of how stars form, and how galaxies grow and interact with each other, coming together to form groups and clusters.

NASA completes record sustained burn of revolutionary rocket engine

Posted by in categories: chemistry, space travel

NASA has pushed forward a revolutionary new rocket technology at its Marshall Space Flight Center in Huntsville, Alabama. Engineers at the facility fired the 3D-printed Rotating Detonation Rocket Engine (RDRE) for a record 251 seconds with 5,800 lb (2,631 kg) of thrust.

For over six decades, NASA has relied on chemical rockets to launch its vehicles into space. It works, but chemical rockets suffer from the fact that they’ve been operating in the neighborhood of their theoretical limit since 1942. This isn’t helped by the fact that most liquid rockets are essentially unchanged in their basic design since the days of the German V2s.

SpaceX’s Falcon Heavy sends the secret X-37B to orbit for seventh flight

Posted by in categories: robotics/AI, space travel

The launch was delayed twice this month due to weather and technical issues.

SpaceX did not show any footage of the X-37B separating from the rocket’s second stage, as the mission was shrouded in secrecy. The X-37B, which looks like a miniature version of the space shuttle, is an autonomous reusable vehicle that can stay in orbit for years, performing various experiments and maneuvers. It is operated by the Air Force in partnership with the Space Force and built by Boeing. There are two X-37B spacecraft in the fleet, and they have flown six missions since 2010.

Meet Valkyrie, NASA’s humanoid robot enters advanced stages of testing

Posted by in categories: robotics/AI, space travel

The robot is being developed to offer an helping hand to astronauts, designed to operate in hostile and hazardous conditions in space.

NASA’s first bipedal humanoid robot, Valkyrie, is undergoing a few of its final testing phases at NASA’s Johnson Space Center in Houston, Texas.

A humanoid, much like Iron Man but constructed from metal and electronics, mimics human walking and appearance. Designed for a diverse array of functions, NASA is exploring if such machines can further space exploration, starting with the Artemis mission, according to Reuters.

Japan sets third launch attempt of next-gen rocket for February

Posted by in category: space travel

Japan’s space agency announced Thursday it will launch its next-generation H3 rocket in February after two failed attempts early this year.

The rocket, billed as a flexible and cost-effective new flagship, is scheduled to lift off between 9:22 am and 1:06 pm (0022 and 406 GMT) on February 15 from the southern island of Tanegashima, the Japan Aerospace Exploration Agency (JAXA) said in a press release.

The third launch attempt comes after the spacecraft was forced to self-destruct in March when the command center concluded its mission could not succeed.

Lost in space? Just use relativity

Posted by in category: space travel

One of the hardest things for many people to conceptualize when talking about how fast something is going is that they must ask, “Compared to what?” All motion only makes sense from a frame of reference, and many spacecraft traveling in the depths of the void lack any regular reference from which to understand how fast they’re going.

There have been several different techniques to try to solve this problem, but one of the ones that have been in development the longest is StarNAV—a way to navigate in space using only the stars.
