More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it now has a unique view of the nearest stars. “It’s fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI) in Boulder, Colorado. «Read the rest of this article» Sections: Technology | No Comments
NASA Lucy Spacecraft to navigate to Jupiter’s Trojan AsteroidsWritten by Tamsyn Brann
In 2021, the feat of navigation that is the Lucy mission will launch. To steer Lucy towards its targets doesn’t simply involve programming a map into a spacecraft and giving it gas money – it will fly by six asteroid targets, each in different orbits, over the course of 12 years. ![]() This diagram illustrates Lucy’s orbital path. The spacecraft’s path (green) is shown in a frame of reference where Jupiter remains stationary, giving the trajectory its pretzel-like shape. After launch in October 2021, Lucy has two close Earth flybys before encountering its Trojan targets. In the L4 cloud Lucy will fly by (3548) Eurybates (white), (15094) Polymele (pink), (11351) Leucus (red), and (21900) Orus (red) from 2027-2028. After diving past Earth again Lucy will visit the L5 cloud and encounter the (617) Patroclus-Menoetius binary (pink) in 2033.

NASA’s Parker Solar Probe uses Venus gravity assist to get closer to the SunWritten by Sarah Frazier
This maneuver, called a gravity assist, reduced Parker’s speed relative to the Sun by 10 percent — amounting to 7,000 miles per hour — drawing the closest point of its orbit, called perihelion, nearer to the star by 4 million miles. ![]() NASA’s Parker Solar Probe completed its first flyby of Venus on Oct. 3, 2018, during a Venus gravity assist, where the spacecraft used the planet’s gravity to alter its trajectory and bring it closer to the Sun.

NASA’s GRACE-1 and GRACE-2 satellites end operationsWritten by Steve Cole
GRACE made science measurements by precisely measuring the distance between its twin satellites, GRACE-1 and GRACE-2, which required that both spacecraft and their instruments be fully functional. ![]() Illustration of the Gravity Recovery and Climate Experiment (GRACE) twin satellites in orbit.

NASA’s Voyager 2 Spacecraft data suggests Uranus may have Two Additional MoonsWritten by Elizabeth Landau
Rob Chancia, a University of Idaho doctoral student, spotted key patterns in the rings while examining decades-old images of Uranus’ icy rings taken by Voyager 2 in 1986. He noticed the amount of ring material on the edge of the alpha ring — one of the brightest of Uranus’ multiple rings — varied periodically. A similar, even more promising pattern occurred in the same part of the neighboring beta ring. ![]() Uranus is seen in this false-color view from NASA’s Hubble Space Telescope from August 2003. The brightness of the planet’s faint rings and dark moons has been enhanced for visibility. (NASA/Erich Karkoschka (Univ. Arizona)) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Transiting Exoplanet Survey Satellite (TESS) will search for life on planets near EarthWritten by Elaine Hunt
When a planet passes in front of, or transits, its parent star, it blocks some of the star’s light. TESS searches for these telltale dips in brightness, which can reveal the planet’s presence and provide additional information about it. ![]() TESS will look at the nearest, brightest stars to find planetary candidates that scientists will observe for years to come.

NASA to release Kepler Space Telescope’s latest discoveries May 10thWritten by Felicia Chou
When Kepler was launched in March 2009, scientists did not know how common planets were outside our solar system. Thanks to Kepler’s treasure trove of discoveries, astronomers now believe there may be at least one planet orbiting every star in the sky. «Read the rest of this article» Sections: Technology | No Comments
