‘Club sandwich’ of oceans and ice may exist within Jovian moon
The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon’s makeup. Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one …
First exomoon possibly found
Titan, Europa, Io and Phobos are just a few members of our solar system’s pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded researchers have spotted the first signs of an “exomoon,” and though they say it’s impossible to confirm its presence, the finding is a tantalizing first …
Cascading dunes visible in a Martian crater
A breathtaking new mosaic from ESA’s Mars Express shows a stunning swirling field of dark dunes cascading into sunken pits within a large impact crater. The mosaic was created from two images and focuses on the 108 km-wide Rabe crater. The region is 320 km to the west of the large Hellas impact basin, about halfway …
Students create winning design for NASA’s first flight of Orion
After a year-long competition among high school teams across the country, evaluators from NASA, Lockheed Martin and the National Institute of Aerospace have selected Team ARES, from the Governor’s School for Science and Technology in Hampton, Va., as the winner of the high school portion of the Exploration Design Challenge (EDC). The announcement Friday came …
Kepler finds nearest twin to Earth yet
Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone …
Join in the Cassini Name Game
As NASA’s Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase. Starting in late 2016, the Cassini spacecraft will repeatedly climb high above Saturn’s north pole, flying just outside its narrow F ring. Cassini will probe the water-rich plume of the …
Space sunflower may help telescopes snap pictures of planets
A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The hunt is on for planets that resemble Earth in size, composition and temperature. Rocky …
Scientists detect gravitational waves from birth of the Universe
Astronomers are announcing today that they have acquired the first direct evidence that gravitational waves rippled through our infant universe during an explosive period of growth called inflation. This is the strongest confirmation yet of cosmic inflation theories, which say the universe expanded by 100 trillion trillion times, in less than the blink of an …
Meet NASA’s James Webb Space Telescope – Launch Date: 2018
In a 1.3 million cubic-foot cleanroom at NASA’s Goddard Spaceflight Center in Greenbelt, Md., 18 gold-coated primary mirror segments await installation on NASA’s James Webb Space Telescope. Those mirrors and the telescope’s four science instruments just steps away, will become the most powerful space telescope ever built. “The Hubble Space Telescope has already rewritten the …
Bigelow’s promise: More space at less cost with inflatable space habitats
We’ve all seen or played in one of those inflatable bounce houses at a carnival or a friend’s birthday party. Now just imagine a bounce house that you can live inside of in outer space. While much more advanced than a bounce house, that’s what Bigelow Aerospace is pursuing. They are designing and building inflatable …

Kim Lichtenberg spends her days sampling Martian soil and rocks
RocketSTEM spoke with Dr. Kimberly Lichtenberg, a scientist and engineer who works on NASA’s Mars rover missions at NASA’s Jet Propulsion Laboratory (JPL), Pasadena, Calif., in conjunction with our “Women in Aerospace” series. We spoke about her career at NASA, role models, education and how she became interested in space exploration. Indeed she’s been in …
The Spitzer Space Telescope: 10 years of viewing the Universe’s dark side
More than ten years have now passed since NASA’s fourth “Great Observatory” – the Space Infrared Telescope Facility (SIRFT) – was boosted into orbit from Cape Canaveral Air Force Station, Fla., atop a Delta II rocket. It was intended to complement is three older siblings, the Hubble Space Telescope, the Compton Gamma Ray Observatory and …
How engineers revamped Spitzer to probe exoplanets
Passing its 10th anniversary, NASA’s Spitzer Space Telescope has evolved into a premier observatory for an endeavor not envisioned in its original design: the study of worlds around other stars, called exoplanets. While the engineers and scientists who built Spitzer did not have this goal in mind, their visionary work made this unexpected capability possible. …
Spitzer: Not a politician; Not a carbonated beverage
Most blog readers are no doubt familiar with the world of space telescopes. But have you ever gone to your friends and asked them what comes to mind when they hear the word “Spitzer?” Chances are, they will ask if you are referring to a certain politician… Or maybe a carbonated beverage. Now is the …
David Hearn takes outreach to new level with Kissimmee Park Observatory
Public outreach is an oft used and abused term nowadays, but I find it the wrong label for astronomy. In Astronomy we are reaching out for the stars! What is really meant in this context is knowledge sharing and encouraging people to raise their eyes to the stars. I found it somewhat depressing that a …
Team Unicorn: Intergalactic force of awesome
By all accounts, Team Unicorn should not exist. Like the fabled unicorns of ancient mythology, geek girls are also supposed to be the stuff of myth and legend, whispered about in reverent tones at Comic Con, but only ever seen fleetingly out of the corner of one’s eye. And yet, these magical beasts are very …
