Two companies, OneWeb and SpaceX, are racing to put fleets of thousands of communication satellites into orbit. In March they had their first near-miss. Avoidance maneuvers were successful, but how many more close calls will they face in the future?

White dwarfs have some surprisingly strong magnetic fields, and one team of astronomers may have finally found the reason why. When they cool, they can activate a dynamo mechanism similar to what powers the Earth’s magnetic field.

Ever feel like no matter how far you fly you end up in the same spot? Ingenuity certainly does. The helicopter that has been making dozens of headlines lately for all of the firsts it is achieving as part of its mission on Mars so far has only returned back to its original take-off point. Named Wright Brothers Field, after the brothers who first brought controlled powered flight to Earth, it has been the site of all of Ingenuity’s firsts so far. But now the basic science of Ingenuity’s mission is over and it is time to start moving on, which it did last week to a new “air field”.

It’s widely known by now that the “dark side” of the moon, made famous by Pink Floyd, isn’t actually dark. It gets as much sunlight as the side that is tidally locked facing Earth. However, it is dark in one very important way – it isn’t affected by radio signals emanating from Earth itself. What’s more, it’s even able to see radio waves that don’t make it down to Earth’s surface, such as those associated with the cosmic “Dark Ages” when the universe was only a few hundred million years old. Those two facts are the main reasons the far side of the moon has continually been touted as a potential location for a very large radio telescope. Now, a project sponsored by NASA’s Institute for Advanced Concepts (NIAC) has received more funding to further explore this intriguing concept.

The magnetic fields of Uranus and Neptune are really, seriously messed up. And we don’t know why.

Many planetary systems may get snuffed out before they even get a chance to form, according to new research. The culprit: nearby stars, capable of evaporating entire protoplanetary disks just when they begin to form.

Cosmologists love universe simulations. Even models covering hundreds of millions of light years can be useful for understanding fundamental aspects of cosmology and the early universe. There’s just one problem – they’re extremely computationally intensive. A 500 million light year swath of the universe could take more than 3 weeks to simulate.. Now, scientists led by Yin Li at the Flatiron Institute have developed a way to run these cosmically huge models 1000 times faster. That 500 million year light year swath could then be simulated in 36 minutes.

On March 19th, 2021, the Biden Administration announced that they had nominated a successor for the role of NASA Administrator. Their nominee was Sen. Clarence William Nelson II (aka. Bill Nelson), a Democratic Senator from Florida, an attorney, and a former payload specialist at NASA. On Monday, May 3rd, he assumed the role of 14th NASA Administrator during a ceremony where he was given the oath of office.

Back in March, NASA’s InSight lander detected two large quakes from a geologically active region of Mars called the Cerberus Fossae. Now, using imagery from the Mars Reconnaissance Orbiter, which circles the red planet at an altitude of about 300km, researchers have discovered that the Cerberus Fossae region holds the most recent evidence of volcanic activity ever seen on Mars.

On April 30th, 2021, the Ingenuity Mars Helicopter achieved yet another milestone and set new records with its fourth flight on Mars. This time around, the helicopter took off at 12:33 AM Mars Standard Time (10:49 AM EDT; 07:49 AM PDT) and ascended to an altitude of 5 meters (16 feet). It then traveled south for approximately 133 meters (436 feet) and then back in the space of about two minutes (117 seconds).
