Hubble Spots Unique Object in the Main Asteroid Belt In 1990, the NASA/ESA Hubble Space Telescope was deployed into Low Earth Orbit (LEO). As one of NASA’s Great Observatories – along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope – this instrument remains one of NASA’s larger and more versatile missions. Even after twenty-seven years of service, Hubble continues to make intriguing discoveries, both within our Solar System and beyond. The latest discovery was made by a team of international astronomers led by the Max Planck Institute for Solar System Research. Using Hubble, they spotted a unique objectRead More →

Where Do We Go Next? Building the Deep Space Gateway I don’t have to tell you that the vision of human space exploration in the Solar System has kind of stalled. Half a century ago, humans set foot on the Moon, and we haven’t been back since. Instead, we’ve thoroughly explored every cubic meter of low Earth orbit, going around and around the Earth. In fact, back in 2016, the International Space Station celebrated 100,000 orbits around the Earth. The space shuttle was the last US vehicle capable of taking humans up into orbit, and it was retired back in 2011. So things look prettyRead More →

Scientists Urge Europe to Stick With “Armageddon”-style Asteroid Mission For decades, scientists have known that in near-Earth space there are thousands of comets and asteroids that periodically cross Earth’s orbit. These Near-Earth Objects (NEOs) are routinely tracked by NASA’s Center for Near Earth Object Studies (CNEOS) to make sure that none pose a risk of collision with our planet. Various programs and missions have also been proposed to divert or destroy any asteroids that might pass too closely to Earth in the future. One such mission is the Asteroid Impact & Deflection Assessment (AIDA), a collaborative effort between NASA and the European Space Agency (ESA).Read More →

NASA’s OSIRIS-REx Asteroid Sampler Slingshots Around Earth Friday, Sept. 21 – Catch It If You Can! Artist’s concept shows the OSIRIS-REx spacecraft passing by Earth on Sept. 22, 2017. Credits: NASA’s Goddard Space Flight Center/University of Arizona KENNEDY SPACE CENTER, FL – Barely a year after NASA’s OSIRIS-REx robotic asteroid sampler launched on a trailblazing mission to snatch a soil sample from a pristine asteroid and return it to Earth for research analysis, the probe is speeding back home for a swift slingshot around our home planet on Friday Sept. 22 to gain a gravity assist speed boost required to complete its journey to theRead More →

New Study Says a Fast Radio Burst Happens Every Second in the Universe When astronomers first noted the detection of a Fast Radio Burst (FRB) in 2007 (aka. the Lorimer Burst), they were both astounded and intrigued. This high-energy burst of radio pulses, which lasted only a few milliseconds, appeared to be coming from outside of our galaxy. Since that time, astronomers have found evidence of many FRBs in previously-recorded data, and are still speculated as to what causes them. Thanks to subsequent discoveries and research, astronomers now know that FRBs are far more common than previously thought. In fact, according to a new studyRead More →

More Surface Ice on Mercury than Previously Thought, says New Study Back in 2012, scientists were delighted to discover that within the polar regions of Mercury, vast amounts of water ice were detected. While the existence of water ice in this permanently-shaded region had been the subject of speculation for about 20 years, it was only after the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft studied the polar region that this was confirmed. Based on the MESSENGER data, it was estimated that Mercury could have between 100 billion to 1 trillion tons of water ice at both poles, and that the ice couldRead More →

New Study Says Primordial Asteroid Belt was Empty Between the orbits of Mars and Jupiter lies a disk of rocks, small bodies and planetoids known as the Main Asteroid Belt. The existence of this Belt was first theorized in the 18th century, based on observations that indicated a regular pattern in the orbits of Solar planets. By the following century, regular discoveries began to be made in the space between Mars and Jupiter, prompting astronomers to theorize where the Belt came from. For a long time, scientists debated whether the Belt was the remains of a planet that broke up, or remnants left over fromRead More →

Dawn Probe Finds Evidence of Subsurface Ice on Vesta In 2011, NASA’s Dawn spacecraft established orbit around the large asteroid (aka. planetoid) known as Vesta. Over the course of the next 14 months, the probe conducted detailed studies of Vesta’s surface with its suite of scientific instruments. These findings revealed much about the planetoid’s history, its surface features, and its structure – which is believed to be differentiated, like the rocky planets. In addition, the probe collected vital information on Vesta’s ice content. After spending the past three years sifting through the probe’s data, a team of scientists has produced a new study that indicatesRead More →

Northrop Grumman Acquires Orbital ATK for $9.2 Billion Antares rocket stands erect, reflecting off the calm waters the night before a launch from NASA’s Wallops Flight Facility, VA, on Oct. 28, 2014. Credit: Ken Kremer/kenkremer.com Aerospace giant Northrop Grumman will acquire Orbital ATK for approximately $9.2 billion, in a deal the companies announced Monday and they say will “expand capability” is largely “complementary” and involves “little overlap.” Orbital ATK specializes in a wide variety of launch vehicles, missiles and munitions that Northrup believes will significantly enhance capabilities it lacks while offering Orbital significantly more technical and financial resources to grow sales and business opportunities.

Venus Express Probe Reveals the Planet’s Mysterious Night Side Venus’ atmosphere is as mysterious as it is dense and scorching. For generations, scientists have sought to study it using ground-based telescopes, orbital missions, and the occasional atmospheric probe. And in 2006, the ESA’s Venus Express mission became the first probe to conduct long-term observations of the planet’s atmosphere, which revealed much about its dynamics. Using this data, a team of international scientists – led by researchers from the Japan Aerospace and Exploration Agency (JAXA) – recently conducted a study that characterized the wind and upper cloud patterns on the night side of Venus. In additionRead More →
