NASA launched two small satellites designed to track tropical cyclones hour by hour from a base in New Zealand on Monday, in a project that could improve weather predictions on devastating storms.
The new storm trackers, sent into orbit on a rocket built by US company Rocket Lab, can fly over hurricanes (or typhoons in the Pacific) every hour, compared to every six hours with current satellites.
Researchers will be able to see storms evolve on an hourly basis, said NASA scientist Will McCarty at a press conference for the first launch of the TROPICS mission.
"We still need the large satellites," he added. "What we get from this is the ability to add more information to the flagship satellites that we already have."
A second Rocket Lab-built vessel is due to launch in about two weeks carrying two more satellites to complete a small constellation of four storm-tracking satellites.
The information gathered on rainfall, temperature and humidity could help scientists determine where a hurricane will make landfall and how intense it will be, helping people living in coastal areas be better prepared for possible evacuations.

Glass is typically associated with floor-to-ceiling windows, colorful crafts, and electronic screens. However, it is not only a crucial man-made material but also a naturally occurring substance found in nature. The moon's surface, despite being desolate and barren, contains abundant glassy substances formed by volcanic eruptions, geological movements, and meteorite impacts.

NASA scientists concluded that four of Uranus' largest moons likely contain an ocean layer of water between its core and icy crust.
The NASA study announced Thursday is the first to detail the evolution of the interior makeup and structure of all five large moons - Ariel, Umbriel, Titania, Oberon and Miranda.
It suggests four of the moons hold oceans that could be miles deep aft Control, Cooperation, Classification remain focus of DOD's Space Policy

Earth planning day - Friday, May 5th, 2023. We continue our triage of the "Ubajara" potential drill site in this plan. In the last plan, we brushed the surface and did some further investigation of Ubajara's chemistry and structure (APXS, ChemCam and MAHLI). Information that came down this morning indicated that the target appears to be representative of what we have been seeing recently, as we Exciton fission - one photon in, two electrons out

"When pentacene is excited by light, the electrons in the material rapidly react," explains Prof. Ralph Ernstorfer, a senior author of the study. "It was an open and very disputed question whether a photon excites two electrons directly or initially one electron, which subsequently shares its energy with another electron."

More than 50 million people in Vietnam, Cambodia, Thailand, Laos, and Myanmar draw water for drinking and agriculture from the Mekong River. With customized tools that use NASA observations and data, the people who manage that water supply have been improving their decision-making.
