According to the most widely-accepted theory by astronomers, planetary systems begin as massive clouds of gas and dust (aka. a nebula) that experience gravitational collapse at the center to form new stars. The remaining matter in the system forms a “circumplanetary disk” around the star, which gradually accretes to form young planets. Studying disks in the earliest stages of planetary formation could help answer some hard questions about how the Solar System formed over 4.5 billion years ago.

In the beginning…

Engineers and technicians at the SpaceX Starbase in Boca Chica, Texas, are working on getting the fully-stacked Starship and Super Heavy prototypes ready for their orbital launch test. The most recent step consisted of a static fire test with the BN7 Super Heavy prototype, where the booster was placed on the orbital launch pad and fired one of its thirty-three Raptor 2 engines. News of the test was shared via SpaceX’s official Twitter account and showed the BN7 blasting the launch pad, leading many to wonder what the orbital launch test will look like!

There’s little doubt that we live in a new Space Age, defined by increasing access, greater competition, and the commercial space industry. The titans of this industry are well known and have even become household names. There are old warhorses like Lockheed Martin, Boeing, Northrop Grumman, and United Launch Alliance and fast-rising stars like SpaceX, Blue Origin, Sierra Nevada, Virgin Galactic, and others. But New Zealand and California-based company Rocket Lab has also made a name for itself in recent years, moving from low-cost expendable rocket launches to reusable rockets.

After each use of one of the tools at the end of the Perseverance rover’s arm, the mission’s engineering team always takes images of the tool to make sure everything is still in working order.

For a spacecraft that’s traveled millions of kilometers across space and driven on the surface of Mars, Curiosity is holding up pretty darned well. That’s the assessment from the operations team at NASA Jet Propulsion Laboratory. This week they celebrated ten years of the rover’s exploration across one of the more forbidding terrains in the solar system.

South Korea launched its first robotic mission to the Moon last week, as a SpaceX Falcon 9 successfully launched the Danuri Lunar Pathfinder mission on August 4, 2022 from Florida’s Cape Canaveral Space Force Station.

When the first humans reach Mars, they’ll probably live in habitats that were there ahead of time or in habs made from their landers. Eventually, though, if people are going to settle on Mars in large numbers, they’ll need to become self-sufficient. A group of researchers at Swinburne University in Melbourne, Australia is looking at ways to make it happen. Their goal is in-situ resource utilization on the planet for solutions to building out the materials needed for Mars cities. They’ve come up with a proposal to produce metals for use on Mars, using only what’s available on the planet. It’s the first detailed study of its kind focused on metal production at another world. It has further implications for colonies on the Moon, as well.

In the near future, NASA and other space agencies will send astronauts beyond Low Earth Orbit (LEO) for the first time in over fifty years. But unlike the Apollo Era, these missions will consist of astronauts spending extended periods on the Moon and traveling to and from Mars (with a few months of surface operations in between). Beyond that, there’s also the planned commercialization of LEO and cis-Lunar space, meaning millions of people could live aboard space habitats and surface settlements well beyond Earth.

Wow, what a beauty! While we’ve all turned our attentions to the new James Webb Space Telescope, this image proves Hubble has still has got it where it counts.  

While NASA’s much-lauded Space Launch System stands ready for its maiden flight later this month with the goal of sending astronauts back to the Moon in the next few years, our gazes once again turn to the stars as we continue to ask the question that has plagued humankind since time immemorial: Are we alone? While there are several solar system locales that we can choose from to conduct our search for life beyond Earth, to include Mars and Saturn’s moons, Titan and Enceladus, one planetary body orbiting the largest planet in the solar system has peaked the interest of scientists since the 1970s.

The OSIRIS-REx spacecraft conducted a two-year reconnaissance and sample collection at the asteroid Bennu, providing crucial data about the 500-meter-wide potentially hazardous rubble pile/space rock. When OSIRIS-REx arrived on Dec. 3, 2018, it needed some tricky navigation and precise maneuvers to make the mission work.

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious “stuff” permeates the universe. In particular, it exists in halos surrounding most galaxies. The mass of the halo exerts a strong gravitational influence on the galaxy itself, as well as on others in the neighborhood. That’s pretty much the standard view of dark matter and its influence on galaxies. However, there are problems with the idea of those halos. Apparently, some oddly shaped dwarf galaxies exist that look like they have no halos. How could this be? Do they represent an observationally induced challenge to the prevailing ideas about dark matter halos?

An interstellar meteorite could be hiding in the ocean. Why doesn’t Jupiter have rings like Saturn. The time when Earth’s magnetic field almost collapsed. The shortest day on Earth, and Planet 9 is running out of places to hide. All this and more in this week’s episode of Space Bites.

In a recent study published in the Journal of High Energy Physics, two researchers from Brown University demonstrated how data from past missions to Jupiter can help scientists examine dark matter, one of the most mysterious phenomena in the universe. The reason past Jupiter missions were chosen is due to the extensive amount of data gathered about the largest planet in the solar system, most notably from the Galileo and Juno orbiters. As stated, dark matter is one of the most mysterious phenomena in the universe. One reason is because it’s invisible and does not emit any light. So why study it?

As soon as I saw these new artificial intelligence image creation tools, like DALL-E, I wanted to see how well they’d work for generating space and astronomy images. I’m still on the waiting list for DALL-E 2, so I don’t have any feedback to give there, but I signed up for Midjourney AI, played around with the free account, and then signed up for a full paid account, so I could test out its capabilities.

If you’re a fan of the commercial space industry (aka. NewSpace), then the name Masten Space Systems is sure to ring a bell. For years, this California-based aerospace company has been developing delivery systems to accommodate payloads to the Moon, Mars, and beyond. This included Xoie, the lander concept that won the $1 million Northrop Grumman Lunar X-Prize in 2009, their Xombie and Xodiac reusable terrestrial landers, and the in-Flight Alumina Spray Technique (FAST) that would allow lunar landers to create their own landing pads.

NASA has announced tentative placeholder launch dates for its beast of a rocket, the Space Launch System (SLS), on its maiden flight to deep space. While work still needs to be accomplished to ensure its launch, the tentative dates are currently August 29th, September 2nd, and September 5th. While NASA stressed these are not set dates, the announcement nonetheless puts SLS closer than ever to flight.

On July 12th, 2022, NASA and its partner agencies released the first James Webb Space Telescope (JWST) observations to the public. These included images and spectra obtained after Webb’s commissioning phase, which included the most-detailed views of galaxy clusters, gravitational lenses, nebulae, merging galaxies, and spectra from an exoplanet’s atmosphere. Less than a month after their release, a paper titled “The JWST Early Release Observations” has been made available that describes the observations and the scientific process that went into making them.

Pit craters are found on solid bodies throughout our Solar System, including Earth, Venus, the Moon, and Mars. These craters – which are not formed by impacts — can be indications of underground lava tubes, which are created when the top of a stream of molten rock solidifies and the lava inside drains away, leaving a hollow tube of rock. If a portion of the roof of the tube is unsupported, parts of it may fall in, making a hole or a pit along the lava tube’s path.

Back in 2014, an object crashed into the ocean just off the coast of Papua New Guinea. Data collected at the time indicated that the meteorite just might be an interstellar object, and if that’s true, then it’s only the third such object known (after Oumuamua and Borisov), and the first known to exist on Earth. Launching an undersea expedition to find it would be a long shot, but the scientific payoff could be enormous.
