SpaceX’s next mission for its Falcon Heavy high-capacity rocket is set for June 24, when it’ll take off from NASA’s Kennedy Space Center in Florida with 20 satellites on board that comprise the Department of Defense’s Space Test Program-2. That’s not all it’ll carry however: There also will be cargo pertaining to four NASA missions aboard the private launch vehicle, including materials that will support the Deep Space Atomic Clock, the Green Propellant Infusion Mission and two payloads that will serve scientific missions.

NASA detailed all of these missions in a press conference today, going into more detail about what each will involve and why NASA is even pursuing this research to begin with.

A mysterious large mass of material has been discovered beneath the largest crater in our solar system—the Moon’s South Pole-Aitken basin—and may contain metal from the asteroid that crashed into the Moon and formed the crater, according to a Baylor University study.

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much unexpected mass we detected,” said lead author Peter B. James.

Ph.D., assistant professor of planetary geophysics in Baylor’s College of Arts & Sciences. The crater itself is oval-shaped, as wide as 2,000 kilometers—roughly the distance between Waco, Texas, and Washington, D.C.—and several miles deep. Despite its size, it cannot be seen from Earth because it is on the far side of the Moon.

Combining laser-induced graphene with a range of other materials gives it all sorts of new tricks.

Future neutrino experiments may provide tomographic scans of Earth’s interior by viewing solar neutrinos that pass through our planet’s layers.

The Sun showers Earth with neutrinos, but this “glow” doesn’t dim when the Sun goes down. At night, solar neutrinos penetrate Earth, impinging detectors from below. Like x rays in a medical scanner, these planet-traversing neutrinos might offer information about the material they pass through. New theoretical calculations show that future experiments, such as the Deep Underground Neutrino Experiment (DUNE), could characterize the different layers inside Earth with neutrino-based tomography.

A plastic water bottle can survive the rigors of an active lifestyle, but over time it will collect odd smells and flavors that eventually can’t be scrubbed out. A glass bottle is a better option, naturally eschewing mold and odors, but one wrong move and suddenly it’s a pile of shards. These Squeezable Glass bottles claim to offer the best of both worlds—but have a bit of a misleading claim to fame.

The bottles aren’t actually made from some indestructible self-repairing glass material discovered in a secret lab a decade ago; they’re plastic, which is why they can be squeezed without shattering. However, the insides of the bottles are coated with an incredibly thin layer of silicon dioxide—which is what glass is made from—that’s just 20 nanometers thick. It acts as barrier preventing smells, flavors, mold, and other bad stuff from sticking to the plastic, but it remains completely flexible.

Proponents say this natural alternative to wildfire cleanup is potentially cheaper.

Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much. The finding means that vehicle designers will be able to develop lighter military vehicles without sacrificing safety, or can improve protection without making vehicles heavier.

CMF is a foam that consists of hollow, metallic spheres—made of materials such as stainless steel or titanium—embedded in a metallic matrix made of steel, titanium, aluminum or other metallic alloys. In this study, the researchers used steel-steel CMF, meaning that both the spheres and the matrix were made of steel.

Bone marrow is a soft spongy material that is located inside of the bones. Bone marrow is necessary for the transition that stem cells make to become one of the types of blood cells (red blood cells, platelets or white blood cells). Bone marrow disease occurs when there is some kind of abnormality or interference with the production of blood cells. Leukemia, aplastic anemia and myelodysplastic syndromes (MDS) are three types of bone marrow disorders that affect the production of blood cells and the bone marrow. Symptoms of each type of bone marrow disease will vary according to its severity, but tend to be similar in nature.

A team from NASA and MIT has created a new type of airplane wing — and it could make air travel far more efficient.

In a paper published in the journal Smart Materials and Structures on Monday, the researchers describe how they built an airplane wing from hundreds of identical, lightweight cube-like structures, all bolted together and then covered with a thin polymer material.

The design allows the wing to change shape automatically, adjusting itself to whatever configuration is optimal for the current phase of flight — with one configuration for take-off, for example, and another for landing.
