Blue Origin Will Finally Fly Passengers to the Edge of Space in July

Things have been heating up lately over at Blue Origin, the commercial spaceflight company launched by Amazon founder Jeff Bezos. Since Bezos stepped down as CEO of Amazon to take a more hands-on role with his other projects, the company has made some rather positive strides. This includes a “dress rehearsal” test flight that took place on April 14^th and brought their New Shepard a step closer to bringing passengers to space.

Following the success of this flight, Blue Origin recently announced they are planning to conduct the first crewed flight with the New Shepard by July 20th. In addition to the Blue Origin astronaut crew, one seat is being set aside for a commercial passenger. As of May 5^th, Blue Origin announced that this ticket will be available for auction and that the proceeds will be donated to Blue Origin’s foundation, Club for the Future.

Starlink and OneWeb Have Their First Avoidance Maneuver With Each Other’s Constellations

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?

How can White Dwarfs Produce Such Powerful Magnetic Fields?

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.

Ingenuity Makes a one-way Trip for the First Time, Flying to a new Landing Site

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”.

NASA is Getting Serious About a Radio Telescope on the Moon

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.

Both Uranus and Neptune Have Really Bizarre Magnetic Fields

These composite images show Uranian auroras, which scientists caught glimpses of through the Hubble in 2011. In the left image, you can clearly see how the aurora stands high above the planet's denser atmosphere. These photos combine Hubble pictures made in UV and visible light by Hubble with photos of Uranus' disk from the Voyager 2 and a third image of the rings from the Gemini Observatory in Hawaii and Chile. The auroras are located close to the planet's north magnetic pole, making these northern lights. Credit: NASA, ESA, and L. Lamy (Observatory of Paris, CNRS, CNES)

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

Young Stars can Evaporate Nearby Disks Before They can Form Planets

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.

A new Method Simulates the Universe 1000 Times Faster

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 19^th, 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 14^th NASA Administrator during a ceremony where he was given the oath of office.

Volcanoes on Mars Might Still be Active

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.
