During the mission’s approach phase, between mid-August and early December, the spacecraft traveled 1.4 million miles (2.2 million km) on its journey from Earth to arrive at a location 12 miles (19 km) from Bennu on December 3rd, 2018. ![]() This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km).

NASA’s Mars InSight Lander will study the Deep Interior of MarsNASA’s Jet Propulsion Laboratory
NASA has a long and successful track record at Mars. Since 1965, it has flown by, orbited, landed and roved across the surface of the Red Planet. What can InSight — planned for launch in May — do that hasn’t been done before? «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Odyssey orbiter recovering from Protective StatusWritten by Guy Webster
The Odyssey project team has diagnosed the cause — an uncertainty aboard the spacecraft about its orientation with regard to Earth and the sun — and is restoring the orbiter to full operations. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Juno Spacecraft set to make another pass over JupiterWritten by DC Agle
The decision was made in order to further study the performance of a set of valves that are part of the spacecraft’s fuel pressurization system. The period reduction maneuver was the final scheduled burn of Juno’s main engine. ![]() This artist’s rendering shows NASA’s Juno spacecraft making one of its close passes over Jupiter.

NASA studies Mars Canyons for signs of liquid waterWritten by Guy Webster
The study published today investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks as resulting from underground water directly reaching the surface. ![]() Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. The area mapped here has the highest density of known RSL on Mars.

NASA Telescopes reveal star FU Orionis continues to devour gas around itWritten by Elizabeth Landau
This brightening is the most extreme event of its kind that has been confirmed around a star the size of the sun, and may have implications for how stars and planets form. The intense baking of the star’s surrounding disk likely changed its chemistry, permanently altering material that could one day turn into planets. ![]() The brightness of outbursting star FU Orionis has been slowly fading since its initial flare-up in 1936. Researchers found that it has dimmed by about 13 percent in short infrared wavelengths from 2004 (left) to 2016 (right).

NASA’s OSIRIS-REx spacecraft to map asteroid Bennu before collecting sampleWritten by Elizabeth Zubritsky
Bennu is part of the debris left over from the formation of the solar system and is pristine enough to hold clues to that very early history. OSIRIS-REx – which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer – will study Bennu in detail and collect a sample to send to Earth for in-depth analysis. The mission also will investigate how pressure from sunlight influences the path of this traveling asteroid. ![]() The mapping of the near-Earth asteroid Bennu is one of the science goals of NASA’s OSIRIS-REx mission, and an integral part of spacecraft operations. The spacecraft will spend a year surveying Bennu before collecting a sample that will be returned to Earth for analysis.

NASA’s Spitzer Space Telescope takes infrared image of The Spider NebulaWritten by Elizabeth Landau
The Spider, officially named IC 417, lies near a much smaller object called NGC 1931, not pictured in the image. Together, the two are called “The Spider and the Fly” nebulae. Nebulae are clouds of interstellar gas and dust where stars can form. ![]() The Spider Nebula lies about 10,000 light-years away from Earth and is a site of active star formation.

NASA’s Juno Spacecraft adjusts course to JupiterWritten by DC Agle
“This is the first of two trajectory adjustments that fine tune Juno’s orbit around the sun, perfecting our rendezvous with Jupiter on July 4th at 8:18pm PDT [11:18pm EDT],” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. ![]() Launched from Earth in 2011, the Juno spacecraft will arrive at Jupiter in 2016 to study the giant planet from an elliptical, polar orbit. Juno will repeatedly dive between the planet and its intense belts of charged particle radiation, coming only 5,000 kilometers (about 3,000 miles) from the cloud tops at closest approach.

NASA to include 13 CubeSats with 2018 launch of unmanned Orion Spacecraft into Deep SpaceWritten by Elizabeth Landau
These small satellite secondary payloads will carry science and technology investigations to help pave the way for future human exploration in deep space, including the Journey to Mars. SLS’ first flight, referred to as Exploration Mission-1 (EM-1), provides the rare opportunity for these small experiments to reach deep space destinations, as most launch opportunities for CubeSats are limited to low-Earth orbit. ![]() The Lunar Flashlight, flying as secondary payload on the first flight of NASA’s Space Launch System, will examine the moon’s surface for ice deposits and identify locations where resources may be extracted.
