Pummeling the ground with an estimated 2.5 million pounds (1.1 million kg) of thrust, the largest and most powerful member of United Launch Alliance’s (ULA) Atlas V fleet roared aloft earlier tonight (Saturday, 14 April), to deliver a multi-purpose payload into orbit on behalf of the U.S. Air Force Space Command. Liftoff of the Atlas V 551—equipped with a 17-foot-wide (5-meter) payload fairing, five strap-on solid-fueled rockets and a single-engine Centaur upper stage—occurred from Space Launch Complex (SLC)-41 at Cape Canaveral Air Force Station, Fla., at 7:13 p.m. EDT, right on the opening of tonight’s two-hour “window”...Read More
After an almost five-year journey to the solar system’s largest planet, NASA’s Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. Confirmation that the burn had completed was received on Earth at 8:53 p.m. PDT (11:53 p.m. EDT) Monday, July 4.Read More
NASA has selected eight technology proposals for investment that have the potential to transform future aerospace missions, introduce new capabilities, and significantly improve current approaches to building and operating aerospace systems.Read More
Tucked in the trunk of the latest commercial cargo spacecraft to head for the International Space Station is an expandable structure that has the potential to revolutionize work and life on the space station.
Observations from NASA’s Spitzer Space Telescope have led to the first temperature map of a super-Earth planet — a rocky planet nearly two times as big as ours. The map reveals extreme temperature swings from one side of the planet to the other, and hints that a possible reason for this is the presence of lava flows.Read More
NASA has completed a major milestone on its journey to Mars and is ready to begin another phase of work on its spaceport of the future, where the next generation of astronauts will launch to Mars and other deep-space destinations.Read More
NASA has selected a team to build a new, cutting-edge instrument that will detect planets outside our solar system, known as exoplanets, by measuring the miniscule “wobbling” of stars. The instrument will be the centerpiece of a new partnership with the National Science Foundation (NSF) called the NASA-NSF Exoplanet Observational Research program, or NN-EXPLORE.Read More
NASA astronaut and Expedition 46 Commander Scott Kelly and his Russian counterpart Mikhail Kornienko returned to Earth Tuesday after a historic 340-day mission aboard the International Space Station. They landed in Kazakhstan at 11:26 p.m. EST (10:26 a.m. March 2 Kazakhstan time).Read More
NASA’s Cassini spacecraft will zip past Saturn’s moon Dione on Monday, Aug. 17 — the final close flyby of this icy satellite during the spacecraft’s long mission.
Cassini’s closest approach, within 295 miles (474 kilometers) of Dione’s surface, will occur at 11:33 a.m. PDT (2:33 p.m. EDT). Mission controllers expect fresh images to begin arriving on Earth within a couple of days following the encounter.
Cassini scientists have a bevy of investigations planned for Dione. Gravity-science data from the flyby will improve scientists’ knowledge of the moon’s internal structure and allow comparisons to Saturn’s other moons. Cassini has performed this sort of gravity science investigation with only a handful of Saturn’s 62 known moons.Read More
Icy mountains on Pluto and a new, crisp view of its largest moon, Charon, are among the several discoveries announced Wednesday by the NASA’s New Horizons team, just one day after the spacecraft’s first ever Pluto flyby.
“Pluto New Horizons is a true mission of exploration showing us why basic scientific research is so important,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “The mission has had nine years to build expectations about what we would see during closest approach to Pluto and Charon. Today, we get the first sampling of the scientific treasure collected during those critical moments, and I can tell you it dramatically surpasses those high expectations.”
“Home run!” said Alan Stern, principal investigator for New Horizons at the Southwest Research Institute (SwRI) in Boulder, Colorado. “New Horizons is returning amazing results already. The data look absolutely gorgeous, and Pluto and Charon are just mind blowing.”Read More
