SpaceX Dragon Endeavour With Crew-8 Aboard Docks to International Space Station

NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin arrived at the International Space Station, as the SpaceX Dragon, named Endeavour, docked to the complex at 2:28 a.m. EST on March 5 while the station was 260 statute miles over Newfoundland.

Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station conducted standard leak checks and pressurization between the spacecraft in preparation for hatch opening.

Warping Reality

The goal of science is to understand and master the Universe around us, but could our skill grow so great that we could learn to warp reality itself?

SpaceX Dragon with Crew-8 Aboard Docks to Station

NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin arrived at the International Space Station, as the SpaceX Dragon, named Endeavour, docked to the complex at 2:28 a.m. EST while the station was 260 statute miles over Newfoundland.

Following Dragon’s link up to the Harmony module, the astronauts aboard the Dragon and the space station will begin conducting standard leak checks and pressurization between the spacecraft in preparation for hatch opening scheduled for 4:13 a.m.

Crew-8 will join the space station’s Expedition 70 crew of NASA astronauts Jasmin Moghbeli and Loral O’Hara, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Furukawa Satoshi, and Roscosmos cosmonauts Konstantin Borisov, Oleg Kononenko, and Nikolai Chub. For a short time, the number of crew aboard the space station will increase to 11 people until Crew-7 members Moghbeli, Mogensen, Satoshi, and Borisov return to Earth.

Cold Chemistry is Different

Experiments demonstrate some of the unusual features of molecular reactions that occur in the deep cold of interstellar space.

Many common small molecules are formed in interstellar space, and their low temperatures are expected to have profound effects on their chemical reactions because of quantum-mechanical effects that are masked at higher temperatures. Researchers have now demonstrated some of these cold chemistry phenomena—such as the effects of molecular rotation and collision energy on reaction rates—in a reaction between a hydrogen ion and an ammonia molecule in the lab. The results, while intuitively surprising at first glance, can be explained by a careful theoretical analysis of the quantum chemistry.

Measuring reaction rates at low temperatures is useful for testing quantum-chemical theory because in those conditions molecules may occupy only a few well-defined quantum states. Such experiments could also offer insights into chemical processes in the cold clouds of gas in star-forming regions of interstellar space, where many of the simple molecules that make up solar systems are formed. But low-temperature experiments are difficult, especially for charged atoms and molecules (ions), because they are very sensitive to stray electric fields in the environment, which accelerate and heat up the ions.

Crystalline Quest: The International Pursuit of Lunar Ice Deposits

Chandrayaan-3’s landing on the Moon and subsequent sulfur detection has propelled lunar ice research forward, aiding NASA ’s plans for a sustainable lunar station. These developments highlight the growing collaboration in space exploration.

Building a space station on the Moon might seem like something out of a science fiction movie, but each new lunar mission is bringing that idea closer to reality. Scientists are homing in on potential lunar ice reservoirs in permanently shadowed regions, or PSRs. These are key to setting up any sort of sustainable lunar infrastructure.

In late August 2023, India’s Chandrayaan-3 lander touched down on the lunar surface in the south polar region, which scientists suspect may harbor ice. This landing marked a significant milestone not only for India but for the scientific community at large.

New laser experiment spins light like a merry-go-round

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light constantly nudges things and can even be used to push spacecraft. Light can also spin objects if it carries orbital angular momentum (OAM)—the property associated with a rotating object’s tendency to keep spinning.

Scientists have known that light can have OAM since the early 90s, and they’ve discovered that the OAM of light is associated with swirls or vortices in the light’s phase—the position of the peaks or troughs of the electromagnetic waves that make up the light. Initially, research on OAM focused on vortices that exist in the cross-section of a light beam—the phase turning like the propeller of a plane flying along the light’s path.

But in recent years, physicists at UMD, led by UMD Physics Professor Howard Milchberg, have discovered that light can carry its OAM in a vortex turned to the side—the phase spins like a wheel on a car, rolling along with the light. The researchers called these light structures spatio-temporal optical vortices (STOVs) and described the momentum they carry as transverse OAM.

NASA Revives The Retro ‘Worm’ Logo For Next Mission To The Moon

The Artemis II mission is scheduled to put people back into lunar orbit in 2025, while the Artemis III will see humans return to the lunar surface no earlier than 2026, per Space. America’s manned mission to the moon is the marquee news, but the real news here is that the logo we most associate with NASA is called the “worm.” Quick! Put on some Beastie Boys, y’all, because NASA is once again doing the worm.
