SpaceX's Falcon 9 rocket with 10 satellites launches at Vandenberg Air Force Base, California on Saturday, January 14, 2017. The two-stage rocket lifted off to place 10 satellites into orbit for Iridium Communications Inc. About nine minutes later, the first stage returned to Earth and landed successfully on a barge in the Pacific Ocean south of Vandenberg.

NASA's Cassini spacecraft took these images of the planet's mysterious hexagon-shaped jetstream in early December 2016. The hexagon was discovered in images taken by the Voyager spacecraft in the early 1980s. It's estimated to have a diameter wider than two Earths. Scientists are still trying to figure out what causes it. Cassini was launched in 1997 and is beginning the end of its mission. The probe will dive into Saturn's atmosphere on September 15, 2017, sending back data until its signal is lost.

This artist's impression shows an imagined view from the surface one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO's La Silla Observatory. These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the Solar System. They are the first planets ever discovered around such a tiny and dim star. In this view one of the inner planets is seen in transit across the disc of its tiny and dim parent star.

The future of NASA's planet-hunting Kepler space observatory was in question Wednesday after a part that helps aim the spacecraft failed, the U.S. space agency said. Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, which is the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. Launched in 2009, Kepler has been detecting planets and planet candidates with a wide range of sizes and orbital distances to help scientists better understand our place in the galaxy.

An asteroid is coming! But don't panic. NASA says Asteroid 2012 DA14 will make a record-close pass by Earth on February 15, but it won't hit us. Most asteroids are made of rocks, but some are metal. They orbit mostly between Jupiter and Mars in the main asteroid belt. Scientists estimate there are tens of thousands of asteroids and when they get close to our planet, they are called Near-Earth Objects (NEOs).

Space probe finds 72 new objects near Earth

This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta.

The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Fresh craters often have steep, active slopes, so we are monitoring this crater for changes over time.

The bedrock lithology is also diverse. The crater is a little more than 1-kilometer wide.

Note: When we say "fresh," we mean on a geological scale. The crater is quite old on a human scale.

Just before the 15th anniversary of continuous human presence on the International Space Station on Nov. 2, 2015, U.S. astronaut and commander of the current Expedition 45 crew, Scott Kelly, is breaking spaceflight records. On Friday, Oct. 16, Kelly begins his 383rd day living in space, surpassing U.S. astronaut Mike FinckeÕs record of 382 cumulative days. Kelly will break another record Oct. 29 on his 216th consecutive day in space, when he will surpass astronaut Michael Lopez-AlegriaÕs record for the single-longest spaceflight by an American. Lopez-Alegria spent 215 days in space as commander of the Expedition 14 crew in 2006.

In this July 12 photograph, Kelly is seen inside the Cupola, a special module which provides a 360-degree viewing of the Earth and the space station. On each additional day he spends in orbit as part of his one-year mission, Kelly will add to his record and to our understanding of the effects of long-duration spaceflight.

Kelly is scheduled to return to Earth on March 3, 2016, by which time he will have compiled 522 total days living in space during four missions.

Scott Kelly: 'I feel like I've lived my whole life up here'

A meteor (L) from the Geminids meteor shower enters the Earth's atmosphere past the stars Castor and Pollux (two bright stars, R) on December 12, 2009 above Southold, New York. This meteor shower gets the name "Geminids" because it appears to radiate from the constellation Gemini. Geminids are pieces of debris from an asteroid called 3200 Phaethon. Earth runs into a stream of debris from the object every year in mid-December, causing the meteors. The peak of the shower is expected the night of December 13-14 at about 0500 GMT on December 14.

This image made in infrared light shows water ice is abundant on Pluto's surface. The image was created using two scans of Pluto made by the New Horizons spacecraft on July 14, 2015, when the probe was about 67,000 miles (108,000 kilometers) above Pluto.

Just before the 15th anniversary of continuous human presence on the International Space Station on Nov. 2, 2015, U.S. astronaut and commander of the current Expedition 45 crew, Scott Kelly, is breaking spaceflight records. On Friday, Oct. 16, Kelly begins his 383rd day living in space, surpassing U.S. astronaut Mike FinckeÕs record of 382 cumulative days. Kelly will break another record Oct. 29 on his 216th consecutive day in space, when he will surpass astronaut Michael Lopez-AlegriaÕs record for the single-longest spaceflight by an American. Lopez-Alegria spent 215 days in space as commander of the Expedition 14 crew in 2006.

In this July 12 photograph, Kelly is seen inside the Cupola, a special module which provides a 360-degree viewing of the Earth and the space station. On each additional day he spends in orbit as part of his one-year mission, Kelly will add to his record and to our understanding of the effects of long-duration spaceflight.

Kelly is scheduled to return to Earth on March 3, 2016, by which time he will have compiled 522 total days living in space during four missions.

Rare alignment of planets in morning sky

Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun. - See more at: http://www.caltech.edu/news/caltech-researchers-find-evidence-real-ninth-planet-49523#sthash.JaLsCJd5.dpuf

The Mountainous Shoreline of Sputnik Planum: In this highest-resolution image from NASA's New Horizons spacecraft, great blocks of Pluto's water-ice crust appear jammed together in the informally named al-Idrisi mountains. "The mountains bordering Sputnik Planum are absolutely stunning at this resolution," said New Horizons science team member John Spencer of the Southwest Research Institute. "The new details revealed here, particularly the crumpled ridges in the rubbly material surrounding several of the mountains, reinforce our earlier impression that the mountains are huge ice blocks that have been jostled and tumbled and somehow transported to their present locations."

Cameras outside the International Space Station captured spectacular views Aug. 30 from 257 miles above the Earth of three powerful tropical systems churning across the Pacific and Atlantic Oceans.
In order, Hurricane Lester is seen as it moves westward across the Pacific packing winds of 125 miles an hour. It is followed by video of Hurricane Madeline as it moved westerly across the Pacific as well, with winds in excess of 130 miles an hour. Both storms were on a track that could threaten the big island of Hawaii in the days ahead. Lastly, the station cameras captured a view of Hurricane Gaston as it churned across the open Atlantic with winds of 100 miles an hour.

This artist's impression shows an imagined view from the surface one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO's La Silla Observatory. These worlds have sizes and temperatures similar to those of Venus and Earth and are the best targets found so far for the search for life outside the Solar System. They are the first planets ever discovered around such a tiny and dim star. In this view one of the inner planets is seen in transit across the disc of its tiny and dim parent star.
