When NASA’s InSight descends to the Red Planet on Nov. 26, 2018, it is guaranteed to be a white-knuckle event. Rob Manning, chief engineer at NASA’s Jet Propulsion Laboratory, explains the critical steps that must happen in perfect sequence to get the robotic lander safely to the surface.

Anxiety abounds at NASA as Mars landing day arrives

A NASA spacecraft's six-month journey to Mars neared its dramatic grand finale Monday in what scientists and engineers hoped would be a soft precision landing on flat red plains.

Emergence of three-dimensional order and structure in growing biofilms

Citation: doi:10.1038/s41567-018-0356-9

Single-cell tracking of up to 10,000 bacteria reveals the structure and dynamics of 3D biofilms—providing evidence to suggest that both local ordering and global biofilm architecture emerge from mechanical interactions.

PASADENA, Calif. — NASA's newest Mars robot has already captured a photo of its rusty, dusty home.



The Insight Lander touched down on the Red Planet yesterday (Nov. 26) just before 3 p.m. EST (2000 GMT) and beamed home its first image from the surface mere minutes later.

High-speed camera shows incoming particles cause damage by briefly melting surfaces as they strike

When tiny particles strike a metal surface at high speed—for example, as coatings being sprayed or as micrometeorites pummeling a space station—the moment of impact happens so fast that the details of process haven't been clearly understood, until now.

Probing quantum physics on a macroscopic scale

Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ago. Researchers at Delft University of Technology and the University of Vienna have now devised a macroscopic system that exhibits entanglement between mechanical phonons and optical photons. They tested the entanglement using a Bell test, one of the most convincing and important tests to show a system behaves non-classically.

The subtle success of a complex mindset

The growing influence in many disciplines of concepts rooted in the physics of complex systems is an achievement that warrants celebration.

Atoms stand in for electrons in system for probing high-temperature superconductors

High-temperature superconductors have the potential to transform everything from electricity transmission and power generation to transportation.

High-dimensional one-way quantum processing implemented on d-level cluster states

Citation: doi:10.1038/s41567-018-0347-x

The creation and manipulation of large quantum states is necessary for quantum information processing tasks. Three-level, four-partite cluster states have now been created in the time and frequency domain of two photons on-chip.

All the Light There is to See? 4 x 10⁸⁴ Photons.

The star cluster known as NGC 1866, on the edge of the Large Magellanic Cloud. The observable universe contains at least two trillion galaxies and a trillion trillion (yes, you read it correctly!) stars.

Astronomers have calculated all the light ever produced by all the stars in the cosmos. It’s a lot, but on the cosmic whole, not that much.

First NASA's Viking 1 lander made it down to the surface, followed a couple of weeks later by Viking 2 on August 7th. In the meantime the Viking 1 and 2 orbiters set up shop high above the planet.

Both landers were equipped with what were, at the time, pretty special cameras. These used a mirror to 'scan' a vertical slice of the terrain, digitizing the light with a photodetector. By rotating the mirror slightly and taking another vertical scan an image was slowly built up and transmitted back to Earth.

Analogue black-hole horizons

Citation : doi:10.1038/s41567-018-0367-6

Some gravitational phenomena are difficult or even impossible to observe in real spacetime. Laboratory analogues of black-hole horizons offer new perspectives on field theory effects that might help our understanding of gravitation.

There's something orbiting the sun, way, way beyond the distant realm of Pluto. 

A team of astronomers recently spotted the farthest-known object in the solar system using a telescope atop Hawaii's lofty Mauna Kea, and announced the discovery on Monday. The object, formally called "2018 VG18" but nicknamed "Farout," orbits some 120 Astronomical Units(120*93million miles!)from the sun.
