Maintenance and experiment work continued on Thursday for the Expedition 43 crew.
NASA astronauts Terry Virt and Scott Kelly finished the work they’ve been doing on one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin. Virts also did some preparatory work on a payload rack for a cellular biology experiment scheduled to launch on the next SpaceX mission.
Globular clusters – dazzling agglomerations of up to a million ancient stars – are among the oldest objects in the universe. Though plentiful in and around many galaxies, newborn examples are vanishingly rare and the conditions necessary to create new ones have never been detected, until now.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered what may be the first known example of a globular cluster about to be born: an incredibly massive, extremely [...]
New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets. Many features that appear to be individual jets of material erupting along the length of prominent fractures in the moon's south polar region might be phantoms created by an optical illusion, according to the new study.
The research is being published on Thursday, May 7, in the journal Nature.
"We think most of the observed [...]
Scientists using NASA's Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1,000 times more massive than previously measured. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. This finding promises to tell astronomers more about the evolution and structure of majestic giant spirals, one of the most co [...]
Did you ever want to just look through the eyepiece of a large telescope in space? If you could, you would see a sharp view that was diffraction limited. Unaffected by atmospheric blurring that ultimately plagues earthbound observers, the angular resolution of your diffraction limited view would be determined only by the wavelength of light and diameter of the telescope lens or mirror; the larger the diameter, the sharper the image.
Still, in this working earth-based snapshot a new active ad [...]
Maintenance and experiment work continued on Wednesday for the Expedition 43 crew.
NASA astronauts Terry Virt spent the second consecutive day replacing components inside one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin. Virts also did some preparatory work on a payload rack for a cellular biology experiment scheduled to launch on the next SpaceX mission.
CAPE CANAVERAL AIR FORCE STATION, Fla. -- The 45th Space Wing supported Space Exploration Technologies' (SpaceX) and NASA's successful Pad Abort Test Mission from Launch Complex 40 here Wednesday at 9 a.m., helping to further open the door to human spaceflight returning to the Space Coast.
A combined team of military, government civilians and contractors from across the 45th Space Wing provided support to the mission, including weather forecasts, launch and range operations, security, safet [...]
Have you ever seen the Summer Triangle? The bright stars Vega, Deneb, and Altair form a large triangle on the sky that can be seen rising in the early northern early spring during the morning and rising in the northern fall during the evening.
During summer months, the triangle can be found nearly overhead near midnight. Featured here, the Summer Triangle asterism was captured last month from Gunma, Japan. In the foreground, sporting a triangular shape of its own, is a flowering 500 year old [...]
An international team of astronomers, led by Yale University and University of California scientists, has pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age of 13.8 billion years.
The team discovered an exceptionally luminous galaxy more than 13 billion years in the past and determined its exact distance from Earth using the combined data from NASA's Hubble and Spitzer space telescopes, and the Keck I 10-meter telescope at [...]
NASA astronauts Terry Virts and Scott Kelly spent the day replacing components inside one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.
ESA astronaut Samantha Cristoforetti continued two experiments that are investigating how the body changes while in microgravity. The Triplelux-A experiment aims to gain a better understanding of immune suppression in spaceflight [...]
Crew Dragon's first critical flight test, known as a Pad Abort Test, is expected to take place this Wednesday, May 6, from SpaceX’s Space Launch Complex 40 (SLC-40) in Cape Canaveral, Florida. While the test is originating from the same launch pad we use for operational missions, this is not an operational flight.
This will be the first flight test of SpaceX’s revolutionary new launch abort system, and the odds of encountering delays or issues are high. Fortunately the test doesn’t ne [...]
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that Mars orbiters do not approach each other too closely.
Last year's addition of two new spacecraft orbiting Mars brought the census of active Mars orbiters to five, the most ever. NASA's Mars Atmosphere and Volatile Evolution (MAVEN) and India's Mars Orbiter Mission joined the 2003 Mars Express from ESA (the European Space Agency) and two from NASA: the 2001 Mars Odyssey and the 2006 Mars Rec [...]
What's that under the surface of Mercury? The robotic MESSENGER spacecraft that had been orbiting planet Mercury for the past four years had been transmitting its data back to Earth with radio waves of very precise energy. The planet's gravity, however, slightly changed this energy when measured on Earth, which enabled the reconstruction of a gravity map of unprecedented precision.
Here gravitational anomalies are shown in false-color, superposed on an image of the planet's cratered surface. [...]
Monday began a new week of science and maintenance work for the Expedition 43 crew.
NASA astronauts Terry Virts and Scott Kelly spent the day reviewing procedures and gathering equipment for an upcoming replacement activity with one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.
ESA astronaut Samantha Cristoforetti participated in the Skin-B experiment which wil [...]

Sometimes the sky lights up unexpectedly. A trip to northern Norway to photograph auroras was not going as well as hoped. It was now past midnight in Steinsvik, Troms, in northern Norway, and the date was 2014 February 8. Despite recent activity on the Sun, the skies were disappointing. Therefore, the astrophotographer began packing up to go. His brother began searching for a missing lens cap.
When the sky suddenly exploded with spectacular aurora. Reacting quickly, a sequence detailing dram [...]
