Richard Branson’s Virgin Orbit Fails on First Rocket Launch Attempt

(LOS ANGELES) — Richard Branson’s Virgin Orbit failed Monday on its first attempt to launch a test satellite into space aboard a rocket carried aloft by a Boeing 747 and released over the Pacific Ocean off the coast of Southern California. The inaugural launch had appeared to be going well until moments after the rocket was dropped from beneath the left wing of the jumbo jet dubbed...

Virgin Orbit’s LauncherOne rocket misses going to space during its first air launch

A new breed of launch vehicle had a shaky first outing today when Virgin Orbit released its LauncherOne rocket from a modified Boeing 747 jumbo jet flying over the Pacific Ocean for its first blastoff. "We've confirmed a clean release from the aircraft," Virgin Orbit reported in a tweet. "However, the mission terminated shortly into the flight." In a follow-up Twitter...

Researchers discover new sex hormone

When University of Ottawa biologists Kim Mitchell and Vance Trudeau began studying the effects of gene mutations in zebrafish, they uncovered new functions that regulate how males and females interact while mating. We sat down with senior author Professor Trudeau, Research Chair in Neuroendocrinology at the Faculty of Science, to learn more.

Solving the space junk problem

Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it's an international agreement to charge operators "orbital-use fees" for every satellite put into orbit.

Galactic crash may have triggered solar system formation

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.

Eating local and plant-based diets: how to feed cities sustainably

How do you feed a city? It is one of the great questions of our time. After all, for a species that ultimately depends on plants to feed ourselves, we do tend to cram ourselves into places that are rather unfriendly towards them. Our cities are built around cars, offices and perhaps the odd park—not fields of crops.

SpaceX and NASA Are Set for a Historic Crewed Launch This Week. Here’s How to Watch

It’s been a long time since the country that once flew nine crewed missions to the moon has been able to launch even a single human being to space aboard its own rockets from its own soil. Ever since the final flight of the space shuttle in July 2011, the U.S. has been dependent on buying rides aboard Russia’s Soyuz spacecraft—at a current $80 million a seat—if it wants...

Johnson and Cummings have revealed their flawed view of what strong leadership is | Suzanne Moore

The question is not whether the prime minister will forgive his adviser, but whether people will forgive this government for failing to keep us safeWe must shield the vulnerable. This is what most of us have understood for the past 10 weeks. Most families have been split apart, often in dire circumstances. For adults and parents of children with compromised immune systems, this remains a...

How drones can monitor explosive volcanoes

Due to high risk for researchers, the imaging of active volcanoes has so far been a great challenge in volcanology. Scientists used a drone for a series of repeated survey flights with optical and thermal imaging cameras at the Santa Maria volcano in Guatemala. A regular and systematic survey of dangerous volcanoes with drones seems to be close.
