Topic: Triton
Voyager 2 is the only spacecraft ever to have flown past Neptune, and it left a lot of unanswered questions. The views were as stunning as they were puzzling, revealing massive, dark plumes of icy material spraying out from Triton‘s surface. But how? Images showed that the icy landscape was young and had been resurfaced over and over with fresh material. But what material, and from where? ![]() This global color mosaic of Neptune’s moon Triton was taken in 1989 by Voyager 2 during its flyby of the Neptune system.

NASA research shows Neptune Moons orbits connected to avoid each other
Orbital dynamics experts are calling it a “dance of avoidance” performed by the tiny moons Naiad and Thalassa. The two are true partners, orbiting only about 1,150 miles (1,850 kilometers) apart. But they never get that close to each other; Naiad’s orbit is tilted and perfectly timed. Every time it passes the slower-moving Thalassa, the two are about 2,200 miles (3,540 kilometers) apart. ![]() Neptune Moon Dance: This photo illustrates how the odd orbits of Neptune’s inner moons Naiad and Thalassa enable them to avoid each other as they race around the planet.

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 SOFIA Observatory to study atmosphere of Neptune’s moon TritonNASA Ames Research Center
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.

NASA’s Voyager Spacecrafts continue exploration after 40 YearsWritten by Elizabeth Landau / Jia-Rui Cook
Their story has not only impacted generations of current and future scientists and engineers, but also Earth’s culture, including film, art and music. Each spacecraft carries a Golden Record of Earth sounds, pictures and messages. Since the spacecraft could last billions of years, these circular time capsules could one day be the only traces of human civilization. ![]() An artist concept depicting one of the twin Voyager spacecraft. Humanity’s farthest and longest-lived spacecraft are celebrating 40 years in August and September 2017. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Kepler space telescope continues new discoveries after major malfunctionWritten by Whitney Clavin
It was late August 2013, and the group of about five employees at Ball Aerospace in Boulder, Colorado, was waiting for NASA’s Kepler space telescope to reveal whether it would live or die. A severe malfunction had robbed the planet-hunting Kepler of its ability to stay pointed at a target without drifting off course. ![]() In this artist’s conception, a tiny rocky object vaporizes as it orbits a white dwarf star. Astronomers have detected the first planetary object transiting a white dwarf using data from the K2 mission. Slowly the object will disintegrate, leaving a dusting of metals on the surface of the star. (CfA/Mark A. Garlick) «Read the rest of this article» Sections: Technology | No Comments

NASA’s New Horizons spacecraft passes Neptune’s Orbit on it’s way to PlutoWritten by Tony Phillips
The sophisticated piano-sized spacecraft, which launched in January 2006, reached Neptune’s orbit — nearly 2.75 billion miles from Earth — in a record eight years and eight months. New Horizons’ milestone matches precisely the 25th anniversary of the historic encounter of NASA’s Voyager 2 spacecraft with Neptune on August 25th, 1989. ![]() NASA’s Pluto-bound New Horizons spacecraft captured this view of the giant planet Neptune and its large moon Triton on July 10, 2014, from a distance of about 2.45 billion miles (3.96 billion kilometers) – more than 26 times the distance between the Earth and sun. The 967-millisecond exposure was taken with the New Horizons telescopic Long-Range Reconnaissance Imager (LORRI).

NASA’s Voyager 2 spacecraft’s restored footage gives Detailed Map of Nepture’s Moon TritonWritten by Elizabeth Landau/Preston Dyches
The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25th, 1989. ![]() The Voyager 2 spacecraft flew by Triton, a moon of Neptune, in the summer of 1989.

NASA’s Voyager 2 spacecraft launched 35 years ago still going strong as it hurtles towards Interstellar SpaceWritten by Jia-Rui Cook
Voyager 2 and its twin, Voyager 1, that launched 16 days later on September 5th, 1977, are still going strong, hurtling away from our sun. Mission managers are eagerly anticipating the day when they break on through to the other side – the space between stars. ![]() Voyager 2 was launched on August 20th, 1977, from the NASA Kennedy Space Center at Cape Canaveral in Florida, propelled into space on a Titan/Centaur rocket.
