NASA has certified SpaceX’s Falcon 9 to launch the space agency’s most valuable and critical scientific spacecraft, opening up the floor for SpaceX to routinely launch missions. As SpaceX nears the Falcon family’s 35th consecutive launch success, this certification serves as a pragmatic endorsement of the years of work the company has put into optimizing Falcon 9 for performance and reliability.
•
Although Falcon 9 is capable of extremely impressive performance beyond Earth orbit, that performance only becomes truly competitive with ULA’s Atlas V rocket when Falcon 9 is launched as a fully expendable vehicle. Regardless, both Falcon 9 and Falcon Heavy are all but guaranteed to cost far less than a comparably capable Atlas V, even assuming no recovery attempt is made. Given the rarity of such valuable NASA launches, typically no more than two annually at best, SpaceX would undoubtedly be more than happy to expend as much hardware as necessary to give NASA a competitive offer for the performance it needs.

After more than half a century of speculation, astronomers and physicists say they have finally confirmed the existence of two Earth-orbiting “moons” entirely made of dust.
•
The hazy clouds of dust (tens of thousands of miles across but too faint to be seen with the naked eye) were first detected almost 60 years ago astronomer Kazimierz Kordylewski. But the patches of light he found were too indistinct to convince scientists that the clouds were really there, and the existence of the "Kordylewski clouds" has long been a matter of controversy.
•
According to the new findings, each Kordylewski cloud is about 15 by 10 degrees wide, or equal to 30 by 20 lunar disks in the night sky. This translates to an area in space about 65,000 by 45,000 miles in actual size, nearly nine times wider than Earth!
•
The clouds themselves are enormous, but the individual particles that comprise them are estimated to measure just a micrometer across. Sunlight reflecting off these particles makes them glow ever so slightly. These satellite clouds, however, have remained hidden in the darkness of space simply because they are very faint.

Diseases that affect the back of the eye (or retina) are difficult to treat because it is challenging to deliver drugs through the dense, vitreous tissue of the eye. But now scientists have created the first nanobots that can easily “swim” through this tissue. The nanobots, which are magnetic and measure 500 nm across, are shaped like propellers and are coated with a liquid layer that prevents them from adhering to eye tissue while they travel through it. They may be loaded with drugs or other therapeutic agents and could be steered to the targeted area using applied magnetic fields.

NASA’s groundbreaking Kepler space observatory, which revolutionized our understanding of planets orbiting other stars, is at the end of its mission. On 11 October, the Deep Space Network turned its gaze to a spot 100 million miles behind Earth in our path around the Sun. There, Kepler turned toward Earth and transmitted the precious data it recently gathered while staring at a patch of sky in the constellation Aquarius.
•
Kepler then tried to resume work, but on 23 October, NASA learned that the spacecraft had entered hibernation mode, a side effect of nearly being out of fuel. NASA has scheduled a media telecon today to officially announce that the mission is over.

NASA’s Parker Solar Probe has made a new record for closest approach to the Sun by a man-made object! Parker surpassed the record of 26.6 million miles set by Helios-2 back in 1976. And it will keep getting closer to the sun until it flies through the corona, for the first time next week, passing within 15 million miles of the solar surface.
•
Launched in August, Parker is on track to set another record late Monday night. It will surpass Helios-2's speed record of 153,454 miles per hour, relative to the sun. Parker will make 24 close approaches to the sun over the next seven years, ultimately coming within just 3.8 million miles.

Currently, cloudy weather limits scientists’ ability to send data to satellites via lasers, because the clouds scatter the lasers’ light. But a powerful, fast-pulsing laser can zap a tiny, cloud-free channel, allowing a second laser to slip through the hole and transmit information.
•
When the first laser passes through a cloud, it rapidly heats the air, setting up a shock wave that shoves the cloud’s water droplets away from the beam. That action creates a channel about a millimeter wide in the cloud, allowing the second laser’s light to make it through the haze. This technique could assist scientists working to create worldwide quantum communications networks that rely on lasers to transmit particles of light, or photons.

Within a billionth of a degree of absolute zero something bizarre can happen: atoms crowd into a single macroscopic quantum wave and form a bizarre state of matter called a Bose-Einstein condensate (BEC). Recently, physicists created a BEC in space!
•
Working in space had one major advantage over a terrestrial lab: an absence of gravity. To be probed, a BEC must be released from its trap of light and electromagnetic fields, and within a fraction of a second it falls to the floor of the vacuum chamber that houses the experiment. But in the weightlessness of space, a BEC released from its trap should just float there, allowing researchers to attempt experiments they can’t do on the ground, such as making bubbles of BEC to probe its quantum nature.
•
To create the BEC in space, researchers designed a special automated rig in which rubidium atoms were trapped on a chip. The rig flew on a small rocket (above) launched from northern Sweden, ascended to an altitude of 243 kilometers. During the 6 minutes of weightlessness the flight provided, researchers achieved a BEC and performed more than 100 measurements on it.

After 3 days of intense debate, a nonbinding vote by planetary scientists resulted in a virtual tie between several candidate landing sites for NASA’s next $2.5 billion Mars rover, due for launch in 2020.
•
All four sites were evaluated both for their suitability as the primary landing site and as an area for continued exploration following the rover’s first couple of years. In turn, each site was rated for the value of the science the rover could conduct itself, with its fleet of instruments, and the value of the samples that it will drill for return to Earth.
•
With 158 votes tallied, Jezero (shown in image) and Northeast Syrtis rated in a near tie for their value as a primary destination, with Midway close behind. Jezero and Midway, in turn, rated higher as destinations for an extended mission. What the vote means will be up to the Mars 2020 team and, ultimately, NASA’s science chief.

A powerful new computer-assisted microscope has for the first time let researchers observe how a mouse embryo develops primitive organs, following the fate of individual cells along the way.
•
The microscope shines a sheet of laser light through the embryo, allowing researchers to see the cells deep inside. Earlier versions of the microscope were able to analyze zebrafish and fruit fly embryos, but mouse embryos are much more difficult. They are not only harder to keep alive in the lab, they are also much larger making it much more difficult to see all the way through them.
•
The microscope uses a form of artificial intelligence in which computers learn from data to track the embryo and keep it in focus as it drifts in its culture medium and grows by an order of magnitude from day 6 to day 8 of development. It also uses advanced algorithms to sort through millions of images to track cells as they move and divide.
•
The new view will help scientists better understand the genes and other factors that shape organs during development. That, in turn, could help them improve their attempts to coax stem cells in the lab to do the same thing.
•
Note: In the image, the blue cells will become part of the heart and green cells will become the neural tube, which later forms the brain and spinal cord.

Solar cells made from perovskites with their record breaking power conversion efficiencies (PCEs) of more than 23% could be ideal for generating sustainable solar energy if they weren’t thermally unstable. A new technique to replace one of the least stable components in these cells could change this.
•
The most efficient perovskite solar cells contain bromide and MA, which unfortunately is thermally unstable. To overcome this problem, researchers replace MA with FA since it is not only more thermally stable than MA but it also has an optimal redshifted bandgap. Unfortunately, because of its large size, FA does distort the perovskite lattice and produces a photoinactive “yellow” phase at room temperature. The other photoactive “black phase” can only be seen at high temperatures.
•
Researchers led by Michael Saliba of the Adolphe Merkle Institute found a way to stabilize the black phase of FA at room temperature. The resulting cells have a PCE of 20.35%, which is one of the highest efficiencies yet for a non-MA perovskite solar cell!

A faint, fleeting supernova may be the key to understanding how neutron star duos are born. Astronomers have spotted what seems to be an ultrastripped supernova: a massive star in its death throes after its outer layers of gas have been siphoned off slowly by a compact companion such as a neutron star or black hole.
•
Most supernovas detonate when a star more than eight times as massive as the sun has burned through all its fuel and can no longer hold itself up against gravity. The star’s core collapses, leaving a dense neutron star behind. Meanwhile, a rebounding explosion ejects the remaining outer layers of gas outward as a bright flare that usually lasts for about 17 to 20 days.
•
But this supernova's light faded over just seven days. It also emitted unusually little energy for a supernova. That wimpy burst suggested that, although the star was about 10 times the sun’s mass to begin with, it ejected only one-fifth of the mass of the sun when it exploded. The best explanation for the puny mass is that the star had lost much of its material sometime before it died.
•
The result of this type of explosion would be a close pair of compact stellar corpses, whether two neutron stars or a neutron star and a black hole. In 2017, astronomers detected gravitational waves emitted from two neutron stars colliding, so researchers know that such duos exist. But it’s unclear how the stars get so close to each other in the first place. The discovery suggests that they were born close and only got closer.

Astronomers across the globe are peering in wonder at the first picture of a black hole’s shadow. The quest to create such an image has involved a massive level of scientific coordination, combining data from telescopes at observatories scattered from the South Pole to Hawaii to the Atacama Desert in Chile!
•
The Event Horizon Telescope, (or EHT) unifies far-flung radio telescopes through a technique called very long baseline interferometry, which involves combining the light waves spotted by each telescope to determine how the light adds up, through a process called interference.
•
Using this technique, EHT can achieve resolution equivalent to picking out a doughnut on the moon! That extreme capability is what’s needed to capture a picture of EHT’s main target: the gigantic black hole at the center of the Milky Way!

No one has ever directly observed a singularity, so scientists still debate the details of what they are like. A boundary known as an event horizon is thought to exist at the edge of each black hole. This border, beyond which nothing can escape is what EHT is attempting to image.

Scientists have created a new cooling paint that can coat nearly any surface, lowering its temperature by over 6°C!
•
The polymer starts as a solution in acetone, to which the researchers add a small amount of water. When painted on a surface, the acetone quickly evaporates, and the polymer separates from the water, creating a network of water droplets. When the water also evaporates, leaving a spongelike arrangement of interconnected voids that reflect up to 99.6% of light, including IR, visible, and UV!
•
The dried film also emits heat primarily in the desirable mid-IR range. Under the relentless midday sun of Phoenix Arizona, (which averages over 37°) painted surfaces remained over 6°C cooler than the surrounding air! Considering 17% of all residential electricity use in the United States is used for air conditioning, energy savings could be substantial.

Under the relentless midday sun of Phoenix Arizona, (which averages over 37°) painted surfaces remained over 6°C cooler than the surrounding air! Considering 17% of all residential electricity use in the United States is used for air conditioning, energy savings could be substantial. ➖🚀➖🛰➖☇➖🔭➖💻➖🔬➖🔧➖🌎➖📐➖💊➖ #celcius

Mosquito larvae eat pretty much anything they can find. They glide through the ponds and puddles, drawing tiny particles of food into their mouths... and miniscule plastic morsels as well. These microplastics stick around in the mosquitoes’ stomachs even after they emerge from the water as flying adults, putting their land predators in danger of ingesting the contaminants.
•
Researchers poured small fluorescent yellow and green plastic beads about the size of red blood cells into water-filled containers of mosquito larvae. When the larvae matured, the team spotted glowing beads inside their Malpighian tubules (structures equivalent to kidneys) confirming that microplastics can linger in an insect’s body even as it shifts from its larval to adult life stage.

These findings indicate that after adult mosquitoes abandon the water, they can introduce the bits of plastic they ate as larvae into their new habitats. That means when nonaquatic predators (including birds, bats, and dragonflies) snack on mosquitoes, they may be in for an unhealthy dose of microplastics from the polluted waters in which their prey were born. Scientists already know microplastics are toxic to many underwater animals. This newly discovered transport route may pose a threat to insect-eating species on land as well.
