Drone Captures Amazing Footage of Falcon 9 Landing Let’s just take a moment to admire how amazing it is when science fiction becomes routinely real: SpaceX CEO Elon Musk shared this amazing drone footage of the Falcon 9 rocket’s first stage returning for a perfect landing after the launch of the Dragon capsule to the International Space Station. It drops flawlessly through the clouds, easy as pie, touching down at SpaceX’s Landing Zone 1 at Cape Canaveral. As cool as the first stage landing was, the launch had a notable starting place. As our Ken Kremer reported yesterday, “the era of undesired idleness for America’sRead More →

Messier 35 – the NGC 2168 Open Star Cluster Welcome back to Messier Monday! In our ongoing tribute to the great Tammy Plotner, we take a look at the open star cluster known as Messier 35. 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 →

Juno Will Get No Closer To Jupiter Due To Engine Troubles On July 4th, 2016, the Juno mission established orbit around Jupiter, becoming the second spacecraft in history to do so (after the Galileo probe). Since then, the probe has been in a regular 53.4-day orbit (known as perijove), moving between the poles to avoid the worst of its radiation belts. Originally, Juno’s mission scientists had been hoping to reduce its orbit to a 14-day cycle so the probe could make more passes to gather more data. To do this, Juno was scheduled for an engine burn on Oct. 19th, 2016, during its second perijovianRead More →

A Region On Mars With Recent Water Is About To Get Major Attention Striations exposed on the surface between Martian sand dunes (one pictured at top) in Lucaya Crater indicate fluctuating levels of salty groundwater. At “a” we see possible cross beds which are tilted layers of sand within larger layers deposited by wind or water. At b, dark and light strata are similar to that exposed in the dune at top and resemble the striations seen in the Namib Desert on Earth. The photo was taken by NASA’s Mars Reconnaissance Orbiter in infrared, red and blue light. Credit: NASA/JPL-Caltech Researcher Dr. Mary Bourke from Trinity CollegeRead More →

Ceres Provides First Detection Of Life’s Building Blocks In Asteroid Belt NASA’s Dawn spacecraft has been poking around Ceres since it first established orbit in March of 2015. In that time, the mission has sent back a steam of images of the minor planet, and with a level of resolution that was previously impossible. Because of this, a lot of interesting revelations have been made about Ceres’ composition and surface features (like its many “bright spots“). In what is sure to be the most surprising find yet, the Dawn spacecraft has revealed that Ceres may actually possess the ingredients for life. Using data from theRead More →

Earth Just Got A New Continent We tend to lump New Zealand and Australia together. They’re similar culturally and share the same geographical position, relative to North America and Europe, anyway. But according to a new paper published in the Geological Society of America Today, it looks like New Zealand and their neighbor New Caledonia are actually their own continent: ‘Zealandia.’ Continent means something different to geographers and geologists. To be considered a geological continent, like Zealandia, the area in question has to satisfy a few conditions: the land in question has to be higher than the ocean floor it has to include a broadRead More →

The Universe Has A Lithium Problem Over the past decades, scientists have wrestled with a problem involving the Big Bang Theory. The Big Bang Theory suggests that there should be three times as much lithium as we can observe. Why is there such a discrepancy between prediction and observation? To get into that problem, let’s back up a bit. The Big Bang Theory (BBT) is well-supported by multiple lines of evidence and theory. It’s widely accepted as the explanation for how the Universe started. Three key pieces of evidence support the BBT: observations of the Cosmic Microwave Background our growing understanding of the large-scale structureRead More →

Poopy Ideas Net $30,000 For Challenge Finalists You may have thought that whole ‘going to the bathroom in space’ issue had already been resolved, with the International Space Station operating continuously with crew on board since 2000. But as we reported back in December, long-duration, deep-space human missions will create a possible scenario of needing to take care of human waste in a spacesuit longer than just a couple of hours. And so NASA and HeroX issued a Space Poop Challenge, to create an “in-suit waste management system” that can handle six days’ worth of bathroom needs. HeroX announced this week that five thousand differentRead More →

Will You Be The Discoverer Of Planet 9? Citizen science projects are a great way for anyone to be involved in the scientific process. Average, everyday folks have discovered things like supernovae, previously unseen craters on the Moon and Mars and even new planets orbiting a distant star. Now, you could be part of one of the most exciting quests yet: finding a mysterious, unseen planet in te far reaches of our own solar system. Last year, Caltech astronomers Mike Brown and Konstantin Batygin found indirect evidence for the existence of a large planet, likely located out past Pluto, and since then, the search hasRead More →

What is the Weather like on Saturn? Welcome back to our planetary weather series! Next up, we take a look at the ringed-beauty, Saturn! Saturn is famous for many things. Aside from its ring system, which are the most visible and beautiful of any gas giant, it is also known for its extensive system of moons (the second largest in the Solar System behind Jupiter). And then there its banded appearance and gold color, which are the result of its peculiar composition and persistent weather patterns. Much like Jupiter, Saturn’s weather systems are known for being particularly extreme, giving rise to features that can beRead More →

Video of Green Comet 45P Puts You Close To The Action This animation of comet 45P/H-M-P is composed of thirteen delay-Doppler images made during 2 hours of observation using the Arecibo Observatory on Feb. 12. Credit: USRA Comets hide their central engines well. From Earth, we see a bright, fuzzy coma and a tail or two. But the nucleus, the source of all the hubbub, remains deeply camouflaged by dust, at best appearing like a blurry star. To see one up close, you need to send a spacecraft right into the comet’s coma and risk getting. Or you can do the job much more cheaply by bouncingRead More →

India Sets Record With 104 Satellites In Single Launch India’s national space agency – the Indian Space Research Organization (ISRO) – has come a long way in recent years. In 2008, the agency launched its first lunar explorer, Chandrayaan-1, which also deployed a lander (the Moon Impact Probe) to the surface. And then there was the Mangalayaan mission – aka. the Mars Orbiter Mission (MOM) – which made history on Sept. 24th, 2014, when it became the first probe to enter orbit around Mars on the first try. In their latest feat, the ISRO established a new record for the number of satellites launched inRead More →

Dream Chaser Spacecraft May Be Used For Hubble Repair Mission The final servicing mission to the venerable Hubble Space Telescope (HST) was in 2009. The shuttle Atlantis completed that mission (STS-125,) and several components were repaired and replaced, including the installation of improved batteries. The HST is expected to function until 2030 – 2040. With the retiring of the shuttle program in 2011, it looked like the Hubble mission was destined to play itself out. But now there’s talk of another servicing mission to the Hubble, to be performed by the Dream Chaser Space System. A view of the Hubble Space Telescope from inside spaceRead More →

Chance Discovery Of A Three Hour Old Supernova Supernovae are extremely energetic and dynamic events in the universe. The brightest one we’ve ever observed was discovered in 2015 and was as bright as 570 billion Suns. Their luminosity signifies their significance in the cosmos. They produce the heavy elements that make up people and planets, and their shockwaves trigger the formation of the next generation of stars. There are about 3 supernovae every 100 hundred years in the Milky Way galaxy. Throughout human history, only a handful of supernovae have been observed. The earliest recorded supernova was observed by Chinese astronomers in 185 AD. TheRead More →
