This picture is from Mars. It's probably not what you think. | Space

It's some next-level skywatching: Scientists are using images captured by NASA's InSight lander to look for meteors on Mars .

From a glance at the resulting images, the search seems straightforward: Countless streaks fill the sky. But squint a little, and the story turns out to be more quixotic. The images show mostly ghosts, the invisible made visible and the visible drowned out amid the illusions.

* * *

 The images come from a device called the Instrument Context Camera, one of two perched on the InSight lander. The camera was included to help scientists understand the neighborhood in which the spacecraft deployed its two main instruments.

All about the laser (and microphone) atop Mars 2020, NASA's next rover

Scientists can also use the information from SuperCam to help decide whether to capture rock cores for the rover's sample caching system. Mars 2020 will collect these core samples in metal tubes, eventually depositing them at a predetermined location for a future mission to retrieve and bring back to Earth.

* * *

SuperCam is essentially a next-generation version of the Curiosity rover's ChemCam. Like its predecessor, SuperCam can use an infrared laser beam to heat the material it impacts to around 18,000 degrees Fahrenheit (10,000 degrees Celsius) - a method called laser induced breakdown spectroscopy, or LIBS - and vaporizes it. A special camera can then determine the chemical makeup of these rocks from the plasma that is created.

Nasa is preparing to launch its most ambitious Mars mission ever | WIRED UK

In July, Nasa will launch its latest ambitious mission to Mars, as it lays the groundwork for a manned mission in the near future. An Atlas V-541 rocket will carry a new rover to the Red Planet.

Each of the rover's six wheels is 52.5cm in diameter – slightly larger than the wheels fitted to previous rover, Curiosity, which landed on Mars in 2012. Each wheel has its own motor, and they're attached to the rover via titanium suspension with multiple pivots and struts that distribute its weight evenly.

Discovery of 'rifts' and 'layers' above Mars may aid radio communications on Earth | Space

A NASA probe at Mars made a finding that could help scientists better understand radio interference at Earth.

The Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft found structures in the ionosphere — an electrically charged zone of the upper atmosphere — at the Red Planet. Similar atmospheric structures on Earth are known to cause problems with radio communications.

MAVEN uncovered two types of structures in the Martian ionosphere : "layers" and "rifts." Both of these structures also occur in Earth's ionosphere, where they can interfere with local and long-distance transmissions.

We May Finally Have a Way to Detect Hawking Radiation Leaking From Black Holes

The epic collision between two neutron stars in 2017 really is the science gift that keeps on giving. As they merged, gravitational waves rippled out across the Universe; now reverberations from that event could confirm a decades-old hypothesis about black holes .

Astronomers poring over the gravitational wave data believe they have found evidence of echoes - something that would only occur in the presence of the 'quantum fuzz' produced by Hawking radiation.

A stripped helium star solves the massive black hole mystery -- ScienceDaily

The putative black hole was detected indirectly from the motion of a bright companion star, orbiting an invisible compact object over a period of about 80 days. From new observations, a Belgian team showed that the original measurements were misinterpreted and that the mass of the black hole is, in fact, very uncertain. The most important question, namely how the observed binary system was created, remains unanswered.

A team of astronomers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Potsdam had a closer look at the archival spectrum of LS V+22 25, taken by the Keck telescope at Mauna Kea, Hawaii. In particular, they were interested in studying the abundances of the chemical elements on the stellar surface.

This weekend’s snow moon is also a supermoon - The Washington Post

The second full moon of the decade — called the snow moon — will shine bold and bright in the sky Saturday. Some are even calling it a supermoon, the celestial body's orbit bringing it close enough to Earth that the natural night light will appear a bit brighter than normal. It's the perfect recipe to enjoy a quaint weekend evening gazing upward and enjoying the spectacle.

The full moon will rise at 4:58 p.m. Saturday in Washington, 5:33 p.m. in Oklahoma City and 5:03 p.m. in Los Angeles. It will remain visible all night long, finally retiring about sunrise Sunday.

'Bizarre' turtle managed to survive asteroid that wiped out dinosaurs | Fox News

Fossils of the turtle, known as Laurasichersis relicta , were recently discovered in northern France. The fossils date to around 56 million years ago, 10 million years after the asteroid hit Earth in the Yucatan Peninsula in Mexico. The asteroid may have also acidified Earth's oceans, according to a  study published in October 2019 .

At this point, it's unclear why or how L. relicta  survived the impact blast, according to the study's lead author, palaeontologist Adán Pérez García. "The reason why Laurasichersis survived the great extinction, while none of the other primitive North American, European or Asian land turtles managed to do so, remains a mystery," Pérez García said in a statement .

Could a habitable planet orbit a black hole? | Science | AAAS

In Interstellar , the situation is reversed: The "sun" is cold and space is hot. The black hole itself is an ideal heat sink, the researchers argue, and usable energy can come from the cosmic microwave background (CMB), weak radiation from the big bang that permeates space. At just a few degrees above absolute zero, the CMB is weak, but the extreme gravity of a supermassive black hole would scrunch the radiation into optical wavelengths and funnel it into a narrow beam.

The scientists first published this idea in 2017 . Now, they have firmed up the numbers. In order to receive strong enough CMB light, a planet would need to orbit very close to the black hole's event horizon. Normally an object that close would soon get sucked in. If the black hole is spinning fast, however, close stable orbits are possible .

A Russian satellite is probably stalking a US spy satellite in orbit - MIT Technology Review

On January 20, something rather strange happened in orbit. A Russian satellite suddenly maneuvered itself so that it was closely shadowing a US spy satellite. The pair are now less than 186 miles (300 kilometers) apart—a short distance when it comes to space. While we don't know for sure what's going on, the Russian satellite's actions strongly suggest it is there to spy on the US one—and there is very little the US can do about it.

Russia's official story is that the satellite, called Kosmos 2542, is part of its program to test out satellite "inspection" technologies so that the country can closely observe its own orbital assets. A parent satellite is supposed to deploy a sub-satellite nearby, and then approach and image it.

Terminator Tape Can Help to Efficiently De-Orbit Satellites | Digital Trends

To tackle this problem, a company called Tethers Unlimited has demonstrated a cheap and lightweight solution for safely disposing of satellites once they are no longer required. The solution involves a 230-foot-long strip of conductive tape deployed from the satellite which pulls it into a lower orbit, called, delightfully enough, Terminator Tape.

To test out the system, Tethers Unlimited attached a Terminator Tape module to the Prox-1 CubeSat, launched last June. The module weighs just two pounds and is about the size of a notebook, and can be attached to the outside of the satellite. Once Prox-1 was no longer required, the module was activated by an electric signal which can be either pre-set to a certain time or triggered by the satellite itself.

In Search of Exoplanets With Binary Sunsets | Discover Magazine

Thirty years ago, the only planets we knew of were in our own solar system. Since then, we've discovered thousands orbiting alien suns, but most of these exoplanets are so far away that it's difficult to study them in detail. Though we've learned a lot, one major question remains: How common are planets in star systems with more than one star , like the binary suns that shone on Luke Skywalker's home world in Star Wars ?

Multi-star systems themselves are commonplace; roughly half of sun-sized stars have at least one stellar dance partner circling in orbit with them. But does having a stellar neighbor affect the likelihood of any planets forming around a star? Or would the motions of stars in a multi-star system instead fling a planet away , exiling it to the lonely depths of space?

A Russian satellite seems to be tailing a US spy satellite in Earth orbit - The Verge

A Russian satellite has positioned itself uncomfortably close to an American spy satellite in orbit around Earth, leading space trackers to speculate that the foreign vehicle is doing some spying of its own.

The Russian spacecraft is meant to inspect other satellites, and experts in the space community believe it may now be keeping a watchful eye on the secretive US vehicle. But the motivation behind this in-space stalking is still unknown.

All January, amateur satellite trackers have been keeping tabs on the weird behavior of this Russian probe, known as Kosmos 2542. Launched in November of last year, Kosmos 2542 has been orbiting in the same plane as a satellite operated by the National Reconnaissance Office called USA 245, which has been in space since 2013.

How Big Is the Solar System? – NASA Solar System Exploration

Our solar system is huge. There is a lot of empty space out there between the planets. Voyager 1 , the most distant human-made object, has been in space for more than 40 years and it still has not escaped the influence of our Sun. As of Feb. 1, 2020, Voyager 1 is about 13.8 billion miles (22.2 billion kilometers) from the Sun — nearly four times the average distance from the Sun to icy Pluto.


In an effort to bring these vast distances down to Earth, we've shrunk the solar system to the size of an American football field. If the Sun were the size of a dime on the goal line, Neptune would be 60 yards away.

Solar products shipped from China to the U.S. face Section 201 and 301 tariffs, plus anti-dumping and countervailing duties.

The Trump administration is currently undertaking a midterm review of the Section 201 tariffs and has wide latitude to determine whether and how tariffs will continue. The U.S. Trade Representative is also soliciting comments on the tariff exclusion for bifacial solar panels, with the potential for that exclusion to be removed — again .

Scientists Are Rapidly Finding Weird Materials Older Than the Solar System on Earth - VICE

Scientists have detected grains of stardust that are older than the Sun inside a gigantic meteorite that fell in Chihuahua, Mexico, in 1969, according to a study published on Monday in Nature Astronomy . The discovery comes within weeks of another study that identified the oldest material on Earth inside a separate meteorite that also landed on our planet in 1969, this time in Australia.

In addition to raising the question of why the universe was so generous with space rocks in 1969—the same year that humanity stepped foot on the Moon for the first time—the two studies show that scientists are rapidly finding new ways to identify and study these "presolar" materials.

RIP Spitzer, the Coolest Heat Telescope in the Solar System | WIRED

On Thursday afternoon, NASA operators will send a farewell missive to the Spitzer Space Telescope from the big antenna at the Goldstone Deep Space Communication Complex in Southern California. It will take the radio signal about 10 minutes to make the 165-million-mile journey across interplanetary space. When Spitzer receives the radio command, it will boot into safe mode and relay the command back to Goldstone.

"It's going to be a bittersweet moment," says Michael Werner, a NASA astronomer who has worked as Spitzer's project scientist since 1983, when the telescope was little more than an idea. "I'm sure it's going to be somewhat painful, but I take great pride in my role in making it happen."
