NASA spacecraft typically rely on human-controlled radio systems to communicate with Earth. As collection of space data increases, NASA looks to cognitive radio, the infusion of artificial intelligence into space communications networks, to meet demand and increase efficiency.
“Modern space communications systems use complex software to support science and exploration missions,” said Janette C. Briones, principal investigator in the cognitive communication project at NASA’s Glenn Research Center in Cleveland, Ohio. “By applying artificial intelligence and machine learning, satellites control these systems seamlessly, making real-time decisions without awaiting instruction.”

Launched aboard a Titan IVB/Centaur on 15 October 1997, Cassini had been active in space for nearly 20 years, with 13 years spent orbiting Saturn, studying the planet and its system since entering orbit on 1 July 2004. The voyage to Saturn included flybys of Venus (April 1998 and June 1999), Earth (August 1999), the asteroid 2685 Masursky, and Jupiter (December 2000). Its mission ended on 15 September 2017, when Cassini flew into Saturn's upper atmosphere and burned up at a very high temperature, in order to prevent any risk of contaminating Saturn's moons, some of which have active environments that could potentially bear life. (At that point Cassini lacked sufficient power to leave the Saturn system so it could only be left in orbit where it might collide with a moon or be destroyed). The mission is widely perceived to have been successful beyond expectation. Cassini-Huygens has been described by NASA's Planetary Science Division Director as a "mission of firsts", that has revolutionized human understanding of the Saturn system, including its moons and rings, and our understanding of where life might be found in the Solar System.
Cassini's original mission was planned to last for four years, from June 2004 to May 2008. The mission was extended for another two years until September 2010, branded the Cassini Equinox Mission. The mission was extended a second and final time with the Cassini Solstice Mission, lasting another seven years until 15 September 2017, on which date Cassini was de-orbited by being allowed to burn up in Saturn's upper atmosphere.
The Huygens module traveled with Cassini until its separation from the probe on 25 December 2004; it was successfully landed by parachute on Titan on January 14, 2005. It successfully returned data to Earth for around 90 minutes, using the orbiter as a relay. This was the first landing ever accomplished in the outer Solar System and the first landing on a moon other than our own. Cassini continued to study the Saturn system in the following years.
At the end of its mission, the Cassini spacecraft executed the "Grand Finale" of its mission: several risky passes through the gaps between Saturn and Saturn's inner rings. The purpose of this phase was to maximize Cassini's scientific outcome before the spacecraft was destroyed. The atmospheric entry of Cassini effectively ended the mission, although data analysis and production will continue afterwards.

Voyager 1 is a space probe launched by NASA on September 5, 1977. Part of the Voyager program to study the outer Solar System, Voyager 1 launched 16 days after its twin, Voyager 2. Having operated for 40 years and 10 days as of September 15, 2017, the spacecraft still communicates with the Deep Space Network to receive routine commands and return data. At a distance of 139 AU (2.08×1010 km) from the Sun as of July 1, 2017, it is the farthest spacecraft from Earth as well as the farthest man-made object. It is also the most distant object in the solar system whose location is known, even farther than Eris (96 AU) and V774104 (~103 AU).

On Monday, August 21, 2017, a total solar eclipse, frequently referred to as the “Great American Eclipse“, was visible within a band across the entire contiguous United States passing from the Pacific to the Atlantic coast. In other countries it was only visible as a partial eclipse

25143 Itokawa (/ˌiːtoʊˈkɑːwə/; Japanese: イトカワ [itokawa]) is an Apollo and Mars-crosser asteroid. It was the first asteroid to be the target of a sample return mission, the Japanese space probe Hayabusa, and the smallest asteroid photographed by a spacecraft.

Kepler is a space observatory launched by NASA to discover Earth-size planets orbiting other stars.Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, 2009, into an Earth-trailing heliocentric orbit.
Designed to survey a portion of our region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets, Kepler’s sole scientific instrument is a photometer that continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view. These data are transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star.
In physical cosmology, galaxy filaments (subtypes: supercluster complexes, galaxy walls, and galaxy sheets) are the largest known structures in the universe. They are massive, thread-like formations, with a typical length of 50 to 80 megaparsecs h−1 (163 to 261 million light-years) that form the boundaries between large voids in the universe. Filaments consist of gravitationally bound galaxies. Parts wherein many galaxies are very close to one another (in cosmic terms) are called superclusters.
NASA has reported a catastrophic event is taking place in space, but scientists are still investigating what exactly has happened or happening. Mysterious flashes of X-rays beamed towards Earth before vanishing just 24 hours later, leaving scientists to investigate the source. Initial findings suggest it came from a “completely new type of cataclysmic event”. The phenomenon was captured by NASA’s Chandra X-ray Observatory, stemmed from a galaxy 10.7 billion light years away. The X-ray source, is located in the sky known as Chandra Deep Field-South (CDF-S).

TRAPPIST-1, also designated as 2MASS J23062928-0502285, is an ultra-cool dwarf star that is slightly larger, but much more massive than the planet Jupiter, located 39.5 ly (12.1 pc) from the Sun in the constellation Aquarius. As of February 2017, the dwarf star has been shown to host seven temperate terrestrial planets, a larger number than detected in any other planetary system.
