NASA’s SOFIA Observatory to study atmosphere of Neptune’s moon Triton

 

NASA Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Researchers on the flying observatory SOFIA, the Stratospheric Observatory for Infrared Astronomy, are preparing for a two-minute opportunity to study the atmosphere of Neptune’s moon Triton as it casts a faint shadow on Earth’s surface. This is the first chance to investigate Triton’s atmosphere in 16 years.

On October 5th, as Triton passes in front of a faraway star it will block the star’s light in an eclipse-like event called an occultation. During the celestial alignment, the team aboard the specially equipped Boeing 747SP aircraft will make observations of the distant star’s light as it passes through Triton’s atmosphere.

The borders of Triton's shadow across Earth's surface are indicated by black lines on this map, while the orange line is the path of the shadow's center. SOFIA’s flight path is represented by the red line; the point of the crucial, two-minute observation of Triton as it aligns with the star is marked by the airplane. The red and blue dots represent the ground-based telescopes that will also observe Triton. (DSI/ Karsten Schindler (Map data, Google))

NASA’s New Horizons mission examines Pluto’s jagged ridges of Methane Ice

 

Written by Frank Tavares
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMountain View, CA – NASA’s New Horizons mission revolutionized our knowledge of Pluto when it flew past that distant world in July 2015. Among its many discoveries were images of strange formations resembling giant knife blades of ice, whose origin had remained a mystery.

Now, scientists have turned up a fascinating explanation for this “bladed terrain”: the structures are made almost entirely of methane ice, and likely formed as a specific kind of erosion wore away their surfaces, leaving dramatic crests and sharp divides.

NASA’s SOFIA to Study Kuper Belt Object for Next New Horizons Flyby

 

NASA Ames Research Center

SOFIA Science Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – On July 10th, researchers using NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, will attempt to study the environment around a distant Kuiper Belt Object, 2014 MU69, which is the next flyby target for NASA’s New Horizons spacecraft.

When New Horizons flies by it, MU69 will be the most distant object ever explored by a spacecraft, over a billion miles farther from our sun than Pluto. This ancient Kuiper Belt object is not well understood because it is faint, small (likely 12-25-mile (20-40-kilometer across, or possibly even smaller according to recent ground-based observations), and very far away (approximately 4.1 billion miles from Earth).

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) takes off from Palmdale, California at sunset. SOFIA is a partnership of NASA and the German Aerospace Center (DLR); NASA and DLR have collaborated on a range of activities and signed agreements on June 16 to work together to reduce aircraft noise and advance research into rotorcraft.

NASA Innovative Advanced Concepts selects 22 proposals for advancement

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A mechanical rover inspired by a Dutch artist. A weather balloon that recharges its batteries in the clouds of Venus.

These are just two of the five ideas that originated at NASA’s Jet Propulsion Laboratory in Pasadena, California, and are advancing for a new round of research funded by the agency.

In total, the space agency is investing in 22 early-stage technology proposals that have the potential to transform future human and robotic exploration missions, introduce new exploration capabilities, and significantly improve current approaches to building and operating aerospace systems.

NASA’s New Horizons spacecraft reaches midpoint between Pluto and next destination, Kuiper Belt

 

NASA Headquarters

How time and our spacecraft fly – especially when you’re making history at 32,000 miles (51,500 kilometers) per hour.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Continuing on its path through the outer regions of the solar system, NASA’s New Horizons spacecraft has now traveled half the distance from Pluto – its storied first target – to 2014 MU69, the Kuiper Belt object (KBO) it will fly past on January 1st, 2019.

The spacecraft reached that milestone at midnight (UTC) on April 3rd – or 7:00pm CT on April 2nd – when it was 486.19 million miles (782.45 million kilometers) beyond Pluto and the same distance from MU69.

A KBO among the Stars: In preparation for the New Horizons flyby of 2014 MU69 on Jan. 1, 2019, the spacecraft’s Long Range Reconnaissance Imager (LORRI) took a series of 10-second exposures of the background star field near the location of its target Kuiper Belt object (KBO). (NASA/JHUAPL/SWRI)

NASA looks at the Super Bowl – 5 Things Football has in Common with Space

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As Super Bowl LI in Houston Texas approaches and players, coaches and a host of personnel behind the scenes prepare for the big game in Space City, NASA remains on the cutting edge of human space exploration, setting its sights on the journey to Mars.

A football player’s journey to the end zone, though, has a lot more in common to space exploration than one might think.

Here are five similarities.

NASA’s SOFIA telescope data reveals composition of dwarf planet Ceres

 

NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – New observations show that Ceres, the largest body in the asteroid belt, does not appear to have the carbon-rich surface composition that space- and ground-based telescopes previously indicated.

Using data primarily from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, a team of astronomers has detected the presence of substantial amounts of material on the surface of Ceres that appear to be fragments of other asteroids containing mostly rocky silicates.

The column of material at and just below the surface of dwarf planet Ceres (box) – the top layer contains anhydrous (dry) pyroxene dust accumulated from space mixed in with native hydrous (wet) dust, carbonates, and water ice. (Bottom) Cross section of Ceres showing the surface layers that are the subject of this study plus a watery mantle and a rocky-metallic core. (Pierre Vernazza, LAM–CNRS/AMU)

NASA movie shows what it would be like to land on Pluto

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – What would it be like to actually land on Pluto? This movie was made from more than 100 images taken by NASA’s New Horizons spacecraft over six weeks of approach and close flyby in the summer of 2015.

The video offers a trip down onto the surface of Pluto — starting with a distant view of Pluto and its largest moon, Charon — and leading up to an eventual ride in for a “landing” on the shoreline of Pluto’s informally named Sputnik Planitia.

NASA’s Discovery Program to send missions to Jupiter’s Trojan Asteroids and Metal Asteroid

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.

“Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids, while Psyche will study a unique metal asteroid that’s never been visited before,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “This is what Discovery Program missions are all about – boldly going to places we’ve never been to enable groundbreaking science.”
