That’s a lot of propellant. But instead of shipping all that oxygen, what if the crew could make it out of thin (Martian) air? A first-generation oxygen generator aboard NASA’s Perseverance rover will test technology for doing exactly that. ![]() An illustration of MOXIE and its components. An air pump pulls in carbon dioxide gas from the Martian atmosphere, which is then regulated and fed to the Solid OXide Electrolyzer (SOXE), where it is electrochemically split to produce pure oxygen.

NASA says Black Hole Disappears, only to reappear days later
These collections of ultrahot gas, called black hole coronas, have been known to exhibit noticeable changes in their luminosity, brightening or dimming by up to 100 times as a black hole feeds. ![]() This illustration shows a black hole surrounded by a disk of gas. In the left panel, a streak of debris falls toward the disk. In the right panel, the debris has dispersed some of the gas, causing the corona (the ball of white light above the black hole) to disappear.

NASA’s Transiting Exoplanet Survey Satellite (TESS) launched WednesdayNASA Headquarters
TESS, which is expected to find thousands of new exoplanets orbiting nearby stars, lifted off at 5:51pm CDT Wednesday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. At 6:53pm, the twin solar arrays that will power the spacecraft successfully deployed. ![]() NASA’s next planet-hunter, the Transiting Exoplanet Survey Satellite (TESS), successfully launched on a SpaceX Falcon 9 on April 18, 2018. TESS will search for new worlds outside our solar system for further study. (NASA Television) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Transiting Exoplanet Survey Satellite to look for undiscovered PlanetsNASA Headquarters
“One of the biggest questions in exoplanet exploration is: If an astronomer finds a planet in a star’s habitable zone, will it be interesting from a biologist’s point of view?” said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology (MIT) Kavli Institute for Astrophysics and Space Research in Cambridge, which is leading the mission. “We expect TESS will discover a number of planets whose atmospheric compositions, which hold potential clues to the presence of life, could be precisely measured by future observers.” ![]() Illustration of the Transiting Exoplanet Survey Satellite (TESS) in front of a lava planet orbiting its host star. TESS will identify thousands of potential new planets for further study and observation. (NASA/GSFC) «Read the rest of this article» Sections: Technology | No Comments

NASA to test CubeSat Weather SatelliteWritten by Samson Reiny
Weather satellites have traditionally been large, both in the effort needed to build them and in actual size. They can take several years to build and can be as big as a small school bus. But all of that could change in the future with the help of a shoebox-sized satellite that will start orbiting Earth later this month. ![]() The Microwave Radiometer Technology Acceleration (MiRaTA) satellite, a 3U CubeSat, is shown with solar panels fully deployed, flanking the body of the spacecraft, which has a circular aperture at the top for the microwave radiometer antenna, used for atmospheric science measurements. There are also two small, thin tape-measure antennas on the top, used for UHF radio communication with the ground station.

NASA to study Earth’s Ionosphere during Total Solar EclipseWritten by Lina Tran
But the total solar eclipse will also have imperceptible effects, such as the sudden loss of extreme ultraviolet radiation from the Sun, which generates the ionized layer of Earth’s atmosphere, called the ionosphere. This ever-changing region grows and shrinks based on solar conditions, and is the focus of several NASA-funded science teams that will use the eclipse as a ready-made experiment, courtesy of nature. ![]() The Moon’s shadow will dramatically affect insolation — the amount of sunlight reaching the ground — during the total solar eclipse.

NASA finds Red Dwarf Star with several Earth Size Planets in OrbitWritten by Elizabeth Landau
Or they could harbor exotic lifeforms, thriving under skies of ruddy twilight. Scientists are pondering the possibilities after this week’s announcement: the discovery of seven worlds orbiting a small, cool star some 40 light-years away, all of them in the ballpark of our home planet in terms of their heft (mass) and size (diameter). Three of the planets reside in the “habitable zone” around their star, TRAPPIST-1, where calculations suggest that conditions might be right for liquid water to exist on their surfaces—though follow-up observations are needed to be sure. ![]() This illustration shows the seven planets orbiting TRAPPIST-1, and ultra-cool dwarf star, as they might look as viewed from Earth using a fictional, incredibly powerful telescope.

NASA’s SMAP mission provides Climate, Weather and Agriculture dataWritten by Alan Buis
The findings are presented in a paper published recently in the journal Nature Geosciences by scientists from the Massachusetts Institute of Technology (MIT), Cambridge; and NASA’s Jet Propulsion Laboratory, Pasadena, California. They used SMAP measurements to estimate soil moisture memory in the top 2 inches (5 centimeters) of Earth’s topsoils. «Read the rest of this article» Sections: Technology | No Comments
