NASA explains how it’ll know when InSight touches down on Mars

NASA has detailed how its team will know when the InSight lander touches down on the Red Planet. The process was recently explained by scientists with the Jet Propulsion Laboratory, which has been tasked with managing the mission for the space agency's Science Mission Directorate. Assuming everything goes according to plan, InSight lander will make touch down on November 26.

Verily shelves diabetes-tracking contact lenses

Verily shelves diabetes-tracking contact lenses

An ambitious project to make contact lenses that could track glucose levels for people with diabetes has been shelved, with Alphabet's Verily admitting the technology just wasn't up to scratch yet. The health-centric lenses were one of the company's first public projects to break cover back in 2014, and a headline example of how it would work with the pharmaceutical industry.

Russian Progress 71 spacecraft successfully launches with ISS cargo

Russia's Progress 71 spacecraft has launched with three tons of supplies destined for the International Space Station. The launch took place from Kazakhstan's Baikonur Cosmodrome a little after 1PM EST today. Everything went as planned, according to NASA, which says the spacecraft successfully entered preliminary orbit, deployed its solar arrays, and deployed the antennas used for navigation.

Redefining the kilogram was incredibly difficult, but scientists have done it

Redefining the kilogram was incredibly difficult, but scientists have done it

As you stand in the produce aisle of the local grocery store weighing bananas, few have wondered exactly how we come by the pounds, kilograms, ounces, and grams that are used to measure the weight of something around the world. As it turns out, deciding on a standard way to know that a kilogram is a kilogram is very difficult. Today knowing that a kilogram is a kilogram is done with a set of international prototype kilogram weights made from very hard metals like platinum, but even that isn't entirely accurate.

NASA JPL says recent signal was not from Mars Opportunity rover

NASA JPL says recent signal was not from Mars Opportunity rover

Earlier today, an unofficial bot tracking NASA Deep Space Network activity published a tweet stating that data was being transmitted by the Opportunity rover, which fell silent during a global dust storm on Mars this past summer. The tweet briefly raised hope that the rover had recharged and made contact, but NASA has some bad news.

Supervolcano Campi Flegrei activity hints at future major eruption

Supervolcano Campi Flegrei activity hints at future major eruption

A large, active supervolcano near Naples, Italy, may be transitioning into a pre-eruption state, according to a new study. Called Campi Flegrei, this supervolcano has a colorful history, having produced a super-colossal eruption about 40,000 years ago. The location's most recent eruption was in 1538, though it was far less substantial in size. A new study has found that the supervolcano may be once again accumulating magma.

Russian nuclear rocket engine aims for the ultimate reusability

Russian nuclear rocket engine aims for the ultimate reusability

One of the keys to making space travel between planets more achievable is to make rockets more powerful and reusable. A rocket that can be reused makes space mission of all sorts cheaper. SpaceX has done a good job with this for its Falcon rockets and the Falcon Heavy that it plans to launch in 2020 with its first government payload aboard. While SpaceX and others are using current technology for their rocket engines, a Russian research group claims to have created a rocket engine that uses new tech.

Frozen Super-Earth discovered orbiting nearby Barnard’s star

Frozen Super-Earth discovered orbiting nearby Barnard’s star

Astronomers have announced the discovery of a frozen Super-Earth orbiting Barnard's star, a single star closest to the Sun. According to the study, which included a handful of researchers with the Carnegie Institution for Science, the Super-Earth has a mass that is at least 3.2 times greater than our own planet; the orbit around its star lasts only 233 days and its surface temperature is estimated to be a frigid -150 degrees Celsius.

Huge meteorite impact crater found hidden under Greenland ice

Huge meteorite impact crater found hidden under Greenland ice

NASA has announced the discovery of a massive meteorite impact crater hidden deep beneath the Greenland ice. The crater measures over 19 miles wide and 1,000ft deep, making it one of the top 25 largest impact craters on the planet. The discovery was made by a team of researchers led by the University of Copenhagen's Centre for GeoGenetics at the Natural History Museum of Denmark.

Gaia satellite spots dim, low-density galaxy hiding in the Milky Way’s shadow

Gaia satellite spots dim, low-density galaxy hiding in the Milky Way’s shadow

Massive amounts of data are generated by orbiting scientific platforms like the Hubble, and the ESA's Gaia satellite; so much data that it often takes years for researchers to pour through. An international team of astronomers were pouring through Gaia data recently and discovered a massive "ghost" galaxy hiding behind the shroud of the Milky Way's disc. The new galaxy has been named Antila 2 or Ant 2 and is said to be an extremely low-density galaxy.
