NASA launches two small satellites to track hurricanes
Monday, 08 May 2023 05:22 Write a comment
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.

The Mystery of the Glass Substance in the Chang'e-5 Lunar Soil

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. Lunar glass can rema NASA: Up to 4 of Uranus' moons could have water

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

The assistant secretary of defense for space policy told senators yesterday that his office is "laser focused" on three priorities: space control, space cooperation and space classification.
"On space control, the department will protect and defend our national security interests from the growing scope and scale of space and counterspace threats, and we will protect and defend our service ESA releases image of Earth showing detailed weather patterns

The European Space Agency and Eumetsat on Thursday released a detailed image of the Earth and its weather patterns from the Meteostat Third Generation Imager-1 satellite.
The image, which was taken on March 18, shows cloud formations over large parts of Europe with details that were previously too small to capture in similar composite images.

In the last plan, we brushed the surface and did some further investigation of Ubajara's chemistry and structure (APXS, ChemCam and MAHLI).

"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."
