For the second time in history, a human-made object has reached the space between the stars. NASA's Voyager 2 probe now has exited the heliosphere - the protective bubble of particles and magnetic fields created by the Sun.

NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander, which touched down on Mars just 10 days ago, has provided the first ever "sounds" of Martian winds on the Red Planet. A media teleconference about these sounds will be held today at 12:30 p.m. EST (9:30 a.m. PST). InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast. The winds were consistent with the direction of dust devil streaks in the landing area, which were observed from orbit.

The first spacecraft to attempt a landing on the far side of the moon is due to blast off from a launch facility in China, a historic step in lunar exploration. The Chinese space agency’s Chang’e 4 mission aims to drop a robotic lander and rover into the moon’s vast and unexplored South Pole-Aitken basin, the largest and deepest impact crater in the solar system.

After a two-year chase, a Nasa probe has reached the ancient asteroid Bennu. The robotic explorer Osiris-Rex pulled within 12 miles (19km) of the diamond-shaped object on Monday and will go into orbit around it on 31 December. No spacecraft has ever orbited such a small body.

Mars has just received its newest robotic resident. NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet after an almost seven-month, 300-million-mile (458-million-kilometer) journey from Earth. InSight’s two-year mission will be to study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed.

After a seven-month, 300m-mile journey, Nasa’s Mars InSight probe has reached its destination and touched down near the red planet’s equator. The lander came to a rest on the dusty surface shortly before 8pm GMT on Monday after a nail-biting descent that started when the spacecraft slammed into the Martian atmosphere at 12,300mph and ended minutes later with the probe settled on the ground, its thrusters quiet.

NASA's InSight lander is scheduled to touch down on Mars at approximately 3 p.m. EST, Monday, Nov. 26. NASA TV live coverage of the InSight Mars landing will begin at 2 p.m. Eastern (7 p.m. UTC).

NASA has chosen Jezero Crater as the landing site for its upcoming Mars 2020 rover mission after a five year search, during which every available detail of more than 60 candidate locations on the Red Planet was scrutinized and debated by the mission team and the planetary science community. The rover mission is scheduled to launch in July 2020 as NASA’s next step in exploration of the Red Planet. It will not only seek signs of ancient habitable conditions – and past microbial life -- but the rover also will collect rock and soil samples and store them in a cache on the planet's surface. NASA and ESA (European Space Agency) are studying future mission concepts to retrieve the samples and return them to Earth, so this landing site sets the stage for the next decade of Mars exploration.

The Leonid meteor shower is about to light up the sky. The spectacular should be visible over the weekend, as small space rocks collide with the Earth's atmosphere and light up into shooting stars.

The cosmic weather forecast calls for strong dark matter winds in our region of the Galaxy. The prediction is based on a new study of a nearby collection of stars that are all moving in the same direction. This so-called S1 stream is believed to be the remnant of a dwarf galaxy that was swallowed by the Milky Way billions of years ago. The dark matter from this long-gone galaxy may be blowing past us at roughly 500 km/s, according to the study’s authors. Such a “dark matter hurricane” might leave a detectable imprint in data from dark matter searches.

A huge impact crater has been discovered under a half-mile-thick Greenland ice sheet. The enormous bowl-shaped dent appears to be the result of a mile-wide iron meteorite slamming into the island at a speed of 12 miles per second as recently as 12,000 years ago.

NASA's mission to perform the first reconnaissance of the Trojans, a population of primitive asteroids orbiting in tandem with Jupiter, passed a critical milestone today. NASA has given approval for the implementation and 2021 launch of the Lucy spacecraft.

Two vastly different NASA spacecraft are about to run out of fuel: The Kepler spacecraft, which spent nine years in deep space collecting data that detected thousands of planets orbiting stars outside our solar system, and the Dawn spacecraft, which spent 11 years orbiting and studying the main asteroid belt's two largest objects, Vesta and Ceres. However, the two record-setting missions have more in common than their coincidentally low fuel levels. Both missions gathered data that broke new scientific ground, searching for answers inside and outside our solar system.

For the past couple of months the European Space Agency's Mars Express orbiter has been keeping an eye on a visually striking feature down on the red planet. At first glance it could be easily mistaken for a volcanic plume coming from one of the giant Tharsis shield volcanoes.

“It went from normal to something was wrong pretty quick,” Hague said during his first interview about the event broadcast this morning on NASA’s Facebook page. “The first thing I noticed was being shaken fairly violently side to side. Then there was an alarm in the capsule and a light. I knew once I saw the light that we had an emergency with the boosters."

After briefly going into safe mode last week, NASA’s Chandra X-ray Observatory — which observes galaxies and nebulas from Earth’s orbit — should be getting back to normal operations soon. The cause of the disruption was a small glitch in one of the spacecraft’s instruments used for steering and pointing. But the space agency has since fixed the problem, and the telescope will be back to observing the Universe by the end of the week.

Australian researchers using a CSIRO radio telescope in Western Australia have nearly doubled the known number of 'fast radio bursts'— powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected. Their findings were reported today in the journal Nature.
