Two Rockets at Cape Canaveral

SpaceX’s Axiom-1 is in the foreground on Launch Pad 39A with NASA’s Artemis I in the background on Launch Pad 39B on April 6, 2022. This is the first time two totally different types of rockets and spacecraft designed to carry humans are on the sister pads at the same time—but it won’t be the last as NASA’s Kennedy Space Center in Florida continues to grow as a multi-user spaceport to launch both government and commercial rockets.

An interesting photo-op took place at Launch Complex 39 at NASA’s Kennedy Space Center in Florida last week. On April 6^th, two different rockets were photographed occupying neighboring launch pads – LC 39A and 39B. The former was occupied by the Falcon 9 rocket and Dragon capsule (visible in the foreground) that launched the first all-private mission to the International Space Station (ISS) on April 8^th – the Axiom Mission 1 (Ax-1).

The latter was occupied by the NASA Space Launch System (SLS) rocket and Orion Spacecraft that will be used to conduct the inaugural launch of the Artemis Program (Artemis I) this summer (seen in the background). This is the first time two different types of rockets and spacecraft occupied LC 39’s sister pads simultaneously. This will become the norm in the future as the KSC continues to grow and becomes a multi-user spaceport that launches government and commercial rockets.

Martian Astronauts Will Create Fuel by Having a Shower

When astronauts begin exploring Mars, they will face numerous challenges. Aside from the time and energy it takes to get there and all the health risks that come with long-duration missions in space, there are also the hazards of the Martian environment itself. These include Mars’ incredibly thin and toxic and toxic atmosphere, the high levels of radiation the planet is exposed to, and the fact that the surface is extremely cold and drier than the driest deserts on Earth.

As a result, missions to Mars will need to leverage local resources to provide all the basic necessities, a process known as In-Situ Resource Utilization (ISRU). Looking to address the need for propellant, a team from the Spanish innovation company Tekniker is developing a system that uses solar power to convert astronaut wastewater into fuel. This technology could be a game-changer for missions to deep space in the coming years, including the Moon, Mars, and beyond!

Jupiter and Ganymede are Connected by Magnetic Fields

On July 5th, 2016, NASA’s Juno spacecraft arrived at Jupiter and began its four-year mission (which has since been extended to 2025) to study the gas giant’s atmosphere, composition, magnetosphere, and gravitational environment. Juno is the first dedicated mission to study Jupiter since the Galileo probe studied the system between 1995 and 2003. The images and data it has sent back to Earth have revealed much about Jupiter’s atmosphere, aurorae, polar storms, internal structure, and moons.

In addition, the Juno mission has allowed astronomers to learn more about how magnetic interaction between some of Jupiter’s moons and its atmosphere leads the gas giant to experience aurorae around its northern and southern poles. After analyzing data from Juno’s payload, a team of researchers from the Southwest Research Institute (SwRI) observed how streams of electrons from Ganymede (Jupiter’s largest moon) leave an “auroral footprint” in Jupiter’s atmosphere.

Since the Renaissance astronomer Galileo Galilee first studied the heavens using a telescope he built himself, astronomers have been pushing the boundaries of what they can observe. After centuries of progress, they have been able to study and catalog objects in all but the earliest periods of the Universe. But thanks to next-generation instruments and technologies, astronomers will soon be able to observe the “Cosmic Dawn” era – ca. 50 million to billion years after the Big Bang.

In recent years, astronomers have made discoveries that preview what this will be like, the most recent of which is the galaxy candidate known as HD1. This galaxy is about 13.5 billion light-years from Earth (32.2 billion light-years in terms of “proper distance“), making it the farthest ever observed. This discovery implies that galaxies existed as early as 300 million years after the Big Bang, a finding which could have drastic implications for astronomy and cosmology!

In 2017, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) began to gather light from the Universe to address some of the biggest questions and astrophysics and cosmology. Located at the Dominion Radio Astrophysical Observatory (DRAO) in British Columbia, this interferometric radio telescope has been a game-changer for studying Fast Radio Bursts (FRBs), which remain one of the most mysterious cosmic mysteries facing astronomers today.

In the near future, CHIME will be getting an expansion that will help it more accurately identify where FRBs are coming from. This will consist of a new radio telescope outrigger located at the SETI Institute’s Hat Creek Radio Observatory (HCRO), new outriggers near Princeton, British Columbia, and at the Green Bank Observatory in West Virginia. These will work with the main CHIME telescope to localize CHIME-detected FRBs precisely in the night sky.

If Aliens Were Sending us Signals, This is What They Might Look Like

For over sixty years, scientists have been searching the cosmos for possible signs of radio transmission that would indicate the existence of extraterrestrial intelligence (ETI). In that time, the technology and methods have matured considerably, but the greatest challenges remain. In addition to having never detected a radio signal of extraterrestrial origin, there is a wide range of possible forms that such a broadcast could take.

In short, SETI researchers must assume what a signal would look like, but without the benefit of any known examples. Recently, an international team led by the University of California Berkeley and the SETI Institute developed a new machine learning tool that simulates what a message from extraterrestrial intelligence (ETI) might look like. It’s known as Setigen, an open-source library that could be a game-changer for future SETI research!

Cultured Meat Could Keep Astronauts fed in Space

The term “cultured meat” has become a bit of a buzzword for the health food industry. This refers to meat produced in a lab using in vitro cell cultures derived from animal proteins. For many, this “alternative meat” is vital to combatting climate change by removing one of the chief causes of deforestation (making room for cattle ranches) and global warming (bovine methane emissions). For others, it’s an environmentally-friendly way of ensuring food security in an era of climate change.

But what about as a means of feeding astronauts on long-duration missions or living for extended periods beyond Earth? In this case, cultured meat would be a way of fulfilling the dietary needs of astronauts who would otherwise be entirely dependent on vegetable proteins. The possibility is currently being explored by the European Space Agency (ESA) and could be a game-changer for future missions to the Moon, Mars, and beyond!

The Milky Way has an Inner Ring, Just Outside the Core

This image from the NASA/ESA Hubble Space Telescope reveals a spiral galaxy named Messier 95 (also known as M95 or NGC 3351). Located about 35 million light-years away in the constellation of Leo (The Lion), this swirling spiral was discovered by astronomer Pierre Méchain in 1781, and catalogued by French astronomer Charles Messier just four days later. Messier was primarily a comet hunter, and was often left frustrated by objects in the sky that resembled comets but turned out not to be. To help other astronomers avoid confusing these objects in the future, he created his famous catalogue of Messier objects. Most definitely not a comet, Messier 95 is actually a barred spiral galaxy. The galaxy has a bar cutting through its centre, surrounded by an inner ring currently forming new stars. Also our own Milky Way is a barred spiral. As well as hosting this stellar nursery, Messier 95 is a known host of the dramatic and explosive final stages in the lives of massive stars: supernovae. In March 2016 a spectacular supernova named SN 2012aw was observed in the outer regions of one of Messier 95’s spiral arms. Once the light from the supernova had faded, astronomers were able to compare observations of the region before and after the explosion to find out which star had “disappeared” — the progenitor star. In this case, the star was an especially huge red supergiant up to 26 times more massive than the Sun.

In the past century, astronomers have learned a great deal about the cosmos and our place in it. From discovering that the Universe is in a constant state of expansion to the discovery of the Cosmic Microwave Background (CMB) and the Big Bang cosmological model, our perception of the cosmos has expanded immensely. And yet, many of the most profound astronomical discoveries still occur within our cosmic backyard – the Milky Way Galaxy.

Compared to other galaxies, which astronomers can resolve with relative ease, the structure and size of the Milky Way have been the subject of ongoing discovery. The most recent comes from the Max Planck Institute for Extraterrestrial Physics (MPE), where scientists have found a previously undiscovered inner ring of metal-rich stars just outside the Galactic Bar. The existence of this ring has revealed new insights into star formation in this region of the galaxy during its early history.
