The Saturn 5 was a monster, capable of sending humans and a lander to the Moon and bringing them back again. But the number of heavy lift rockets since then has gotten pretty sparse. Now, with tens if not hundreds of thousands of satellites in the works, giant new space telescopes and multi-ton lunar landers in development there are heavy lift solutions to match. So let’s talk about them! From yesterday's Saturn V to today's Ariane VI, rockets capable of launching large telescopes or small space stations in a single go are modern marvels. They are also wildly dangerous, and not exactly compatible. Let's look at today's fleet of rockets and just what they're accomplishing. 

Hopefully, we’re about to travel back to the Moon relatively soon. And while the original “giant leap for mankind” was taken by a human, Neil Armstrong brought a plethora of other forms of life along with him. Humans themselves are essentially walking ecosystems, and understanding how our microbial companions survive in the harsh environments of space will be critical to ensure the health and safety of future astronauts, no matter where their giant leaps might be. A new PhD thesis from Tommaso Zaccaria at Radboud University showcases just how well-suited to some of these harsh environments terrestrial pathogens actually are.

The telescope should spot billions of astronomical objects in the next 10 years.

The famous opening scene of the Martian has Mark Watney stabbed in the torso with a communications antenna. While this accident sets up the plot for what is widely regarded as a modern classic of sci-fi storytelling, what if he was wearing a space suit that would have stopped the impact altogether? That’s the idea behind a recent NASA Small Business Innovation Research (SBIR) Phase I program run by researchers from Materials Research & Design, Fiber Materials, Inc, and NASA’s Johnson Space Center. Their work, which was recently presented at the National Space & Missile Materials Symposium, showcased a type of advanced 3D-reinforced fabric that could have saved Watney and his compatriots a whole lot of trouble.

Observations of a distant cluster of stars in our galaxy have resulted in a new class of objects that turn out to be galactic building blocks. Researchers used Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) to study the stars that make up Terzan 5, long though to be a globular cluster. What they found puts that cluster into a very rare class of objects called "bulge fossil fragments."

The wreckage of an exploded star is meant to fade quietly, cooling over thousands of years like the embers of a fire. So astronomers were stunned when NASA's Chandra X-ray Observatory caught dozens of these supernova remnants in a nearby galaxy doing the opposite, flaring and flickering in X-rays as though refusing to die. In each case a star appears to have survived its partner's explosion, only to be slowly devoured by the black hole or neutron star its companion left behind. It’s a discovery that turns the calm graveyards of dead stars into something far stranger and more alive.

Jezero Crater on Mars is a 45-kilometer-wide (28-mile) crater that once hosted a lake billions of years ago fed by two distinct river valleys with Jezero eventually forming an exit channel over time. One of Jezero’s most prominent features is the massive river delta that consists of sediments that were deposited as the inflow slowed down. Researchers hypothesize that the delta and lake were formed under freshwater conditions, indicating the potential for life as we know it, also called biosignatures.

Europe's CERN physics research center bids 'Farewell' to the Large Hadron Collider, but it's actually more like 'See You Later, Accelerator!' The new, improved High-Luminosity LHC is due to make its debut in 2030.

After more than eight years of searching and with instruments designed to detect it, the European Space Agency’s (ESA) Mars Trace Gas Orbiter has yet to find methane in the red planet’s atmosphere.

On September 22, 2021, the IceCube Neutrino Detector in Antarctica caught a blast of neutrinos as it passed through the solar system. These neutrinos were remarkably high-energy and came from a galaxy 11 billion light-years away. That's a period of the Universe's history known as "Cosmic Noon". It's when star formation in galaxies was at its most active and that provided an interesting clue to their origin. The source of the neutrinos was nicknamed "Shadow Blaster" because the event that created the neutrinos was hidden by a dense cloud of dust, which made it invisible to optical observations.

Stellar mass black holes may not be black holes at all. Instead, they could be a type of extremely compact star called a gravastar, which mimics a black hole. This is according to theoretical phsyicists who have discovered a solution to Einstein's Theory of General Relativity that doesn't automatically result in a black hole when a star collapses at the end of its life.
