Jared Isaacman has opened up on why he believes his nomination to be NASA administrator was abruptly withdrawn by the White House.
Blue Origin is now targeting Aug. 15 at the earliest for the second-ever launch of its New Glenn rocket, a slip of several months.
In this series we are exploring NASA's top five challenges as detailed in its Civil Space Shortfall Ranking, which is basically NASA's Christmas wish list. These are the technologies that NASA believes we need to develop if we want to go to space…and stay there.
When the Mariner 9 flew past Mars in 1972, scientists were treated to the first evidence that water once flowed on the surface of Mars. Subsequent missions confirmed this theory based on the study of features that form in the presence of water (flow channels, delta fans, and sedimentary deposits), the presence of hydrated minerals and clays in impact basins, and the discovery of subsurface ice and permafrost across the planet. These findings indicate that Mars once had an atmosphere thick enough to maintain temperatures to maintain surface water in a liquid state.
Astronomers recently used a pair of powerful telescopes to zero in on a cosmic battle occurring some 11 billion light-years away from Earth. The combatants are a pair of galaxies charging at each other over and over again, at velocities upwards of 500 kilometers per second. According to one of the scientists studying the scene, one galaxy is cutting into the heart of the other with a blast of radiation. “We hence call this system the ‘cosmic joust,’” said study co-lead Pasquier Noterdaeme of the Institut d'Astrophysique de Paris.
Blink and you'll miss him! The immortal son of Reed Richards and Sue Storm is in the new 'The Fantastic Four: First Steps' trailer, but who is this adorable little Omega-level mutant?

The COSMOS scientific collaboration has released the largest map of the Universe ever created. It contains almost 800,000 galaxies, some from the Universe's earliest times. The map challenges some of our ideas about the early universe.
Getting to Mars takes a really long time, about 9 months using today's rocket technology. This is because regular rocket engines burn fuel and oxygen together (like a car engine), but they're not very efficient. The fundamental problem is that spacecraft must carry both fuel and oxidiser since there's no air in space to support combustion. This creates a vicious circle: the more fuel you carry to go faster, the heavier your spacecraft becomes, requiring even more fuel to accelerate that extra weight. To go faster, you'd need massive amounts of fuel, making the rockets incredibly expensive and heavy. Current chemical propulsion systems are just about at their theoretical limits, with little room for improvement in efficiency.
Asteroid 2024 YR4, once the highest impact risk ever recorded, now poses no threat to Earth but has a slightly increased chance of striking the moon in 2032.
