NASA Twins Study Researchers Take Genetic Data To Next Level People who plan and conduct space missions never tire of telling us how hard it is to do things in space. Our next big goal is getting humans to Mars, and establishing a colony there. There are a multitude of technical and engineering hurdles to be overcome, but we think we can do it. But the other side of the coin is the physiological hurdles to be overcome. Those may prove to be much more challenging to deal with. NASA’s twins study is poised to add an enormous amount of data to our growing bodyRead More →

Last Look At Mimas For A Long Time Since the Cassini mission arrived in the Saturn system in 2004, it has provided some stunning images of the gas giant and its many moons. And in the course of capturing new views of Titan’s dense atmosphere, Iapetus’ curious “yin-yang” coloration, and the water plumes and “tiger stripes” of Enceladus, it snapped the most richly-detailed images of Mimas ever seen. But like all good things, Cassini’s days of capturing close-up images of Mimas are coming to an end. As of January 30th, 2017, the probe made its final close approach to the moon, and took the lastRead More →

Zero2Infinity Successfully Test Launches Its Bloostar Prototype Founded in 2009, the private aerospace company Zero2Infinity – which is headquartered in Barcelona, Spain – was created with the vision of delivering orbital payloads and providing space tourism on a budget. But unlike your conventional aerospace companies – i.e. SpaceX, Blue Origin, Orbital ATK, etc – their plan is to do it all using high-altitude stratospheric balloons. On March 1st, the Zero2Infinity team passed a major milestone, deploying a prototype “rockoon” craft from the National Institute of Aerospace Technology‘s (INTA) facility in El Arenosillo, Spain. Known as Bloostar, this two-stage craft (which consists of a balloon andRead More →

Russia Recruiting For Its Moon Bound Cosmonauts   Roscosmos has certainly come a long way in the past few decades. After facing an uncertain future in the 1990s, the federal space agency has rebounded to become a major player in space and a crucial partner in the International Space Station. And in the coming years, Roscosmos hopes to expand its reach further, with missions planned to the Moon and even Mars. Towards this end, on Tuesday, March 14th, the agency announced that it is conducting a recruitment drive for new cosmonauts. All are welcome, the agency stressed, to apply to become the next-generation of spaceRead More →

How Far is Venus From the Sun? Earth and Venus are often called “sister planets” because they share some key characteristics. Like Earth, Venus is a terrestrial planet (i.e. composed of silicate minerals and metals) and orbits within our Sun’s habitable zone. But of course, they are also some major differences between them, like the fact that Venus’ is atmosphere is extremely dense and the hottest in the Solar System. This is particularly interesting when you consider that Venus is not the closest planet to our Sun (that would be Mercury). In fact, its distance from the Sun is just over 70% the distance betweenRead More →

NASA Brings Trappist-1 Into Focus… Kinda Sorta On February 22nd, 2017, NASA announced the discovery of a seven-planet system around the red dwarf star known as TRAPPIST-1. Since that time, a number of interesting revelations have been made. For starters, the Search for Extra-Terrestrial Intelligence (SETI) recently announced that it was already monitoring this system for signs of advanced life (sadly, the results were not encouraging). In their latest news release about this nearby star system, NASA announced the release of the first images taken of this system by the Kepler mission. As humanity’s premier planet-hunting mission, Kepler has been observing this system since DecemberRead More →

Warm Poles Suggest Enceladus’ Liquid Water Near Surface One of the biggest surprises from the Cassini mission to Saturn has been the discovery of active geysers at the south pole of the moon Enceladus. At only about 500 km (310 miles) in diameter, the bright and ice-covered moon should be too small and too far from the Sun to be active. Instead, this little moon is one of the most geothermally active places in the Solar System. Now, a new study from Cassini data shows that the south polar region of Enceladus is even warmer than expected just a few feet below its icy surface.Read More →

Canada To Get Its Own Spaceport Canada is getting its own rocket-launching facility. Maritime Launch Services (MLS) has confirmed its plans to build and operate a commercial launch facility in Nova Scotia, on Canada’s east coast. The new spaceport should begin construction in 1 year, and should be in operation by 2022. The facility will be built near Canso, in the province of Nova Scotia. Maritime Launch Services hopes to launch 8 rockets per year to place satellites in orbit. The Ukrainian Cyclone 4M medium-class rockets that will lift-off from Canso will have a payload of up to 3,350 kg. The red marker in theRead More →

Trump’s NASA Authorization Act In All Its Glory It’s no secret that NASA has had its share of worries with the Trump administration. In addition to being forced to wait several months to get a sense of the administration’s priorities, the space agency has also had to contend with proposed cuts to its Earth Observation and climate monitoring programs. But one thing which does not appear to be threatened is NASA’s “Journey to Mars“. In accordance with the National Aeronautics and Space Administration Transition Authorization Act of 2017, the Trump administration has finally committed to funding NASA’s plans for deep space human exploration in theRead More →

What’s on the Surface of Venus? We’re always talking about Mars here on the Guide to Space. And with good reason. Mars is awesome, and there’s a fleet of spacecraft orbiting, probing and crawling around the surface of Mars. The Red Planet is the focus of so much of our attention because it’s reasonably close and offers humanity a viable place for a second home. Well, not exactly viable, but with the right technology and techniques, we might be able to make a sustainable civilization there. We have the surface of Mars mapped in great detail, and we know what it looks like from theRead More →

Are You Ready For The NanoSWARM? We’re accustomed to the ‘large craft’ approach to exploring our Solar System. Probes like the Voyagers, the Mariners, and the Pioneers have written their place in the history of space exploration. Missions like Cassini and Juno are carrying on that work. But advances in technology mean that Nanosats and Cubesats might write the next chapter in the exploration of our Solar System. Nanosats and Cubesats are different than the probes of the past. They’re much smaller and cheaper, and they offer some flexibility in our approach to exploring the Solar System. A Nanosat is defined as a satellite withRead More →

Exploring the Universe For Magnetic Fields In the past few decades, astronomers and geophysicists have benefited immensely from the study of planetary magnetic fields. Dedicated to mapping patterns of magnetism on other astronomical bodies, this field has grown thanks to missions ranging from the Voyager probes to the more recent Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. Looking ahead, it is clear that this field of study will play a vital role in the exploration of the Solar System and beyond. As Jared Espley of NASA’s Goddard Space Flight Center outlined during a presentation at NASA’s Planetary Science Vision 2050 Workshop, these goals include advancingRead More →

Strange Loner Planet Gets Astronomers’ Attention In the hunt for exoplanets, some rather strange discoveries have been made. Beyond our Solar System, astronomers have spotted gas giants and terrestrial planets that appear to be many orders of magnitude larger than what we are used to (aka. “Super-Jupiters” and “Super-Earths”). And in some cases, it has not been entirely clear what our instruments have been detecting. For instance, in some cases, astronomers have not been if an exoplanet candidate was a super-Jupiter or a brown dwarf. Not only do these substellar-mass stars fall into the same temperature range as massive gas giants, they also share manyRead More →

Closest Star Around A Black Hole Discovered Imagine being caught in the clutches of a black hole, being whirled around at dizzying speeds and having your mass slowly but continually sucked away. That’s the life of a white dwarf star that is doing an orbital dance with a black hole. And this dancing duo could be the first ultracompact black hole X-ray binary identified in our galaxy. “This white dwarf is so close to the black hole that material is being pulled away from the star and dumped onto a disk of matter around the black hole before falling in,” said Arash Bahramian from theRead More →

Messier 37 – the NGC 2099 Open Star Cluster Welcome back to Messier Monday! In our ongoing tribute to the great Tammy Plotner, we take a look at the Pinweel Cluster, otherwise known as Messier 36. Enjoy! During the 18th century, famed French astronomer Charles Messier noted the presence of several “nebulous objects” in the night sky. Having originally mistaken them for comets, he began compiling a list of them so that others would not make the same mistake he did. In time, this list (known as the Messier Catalog) would come to include 100 of the most fabulous objects in the night sky. OneRead More →
