Engineers at NASA’s Kennedy Space Center in Florida are preparing for the next step in assembling the Space Launch System rocket, which will promote the unmanned test flight of the Artemis I to the moon later this year. The
Temporary Cryogenic Propulsion Stage (ICPS), as shown, will hover on the top of the rocket below the Orion Crew Compartment and finally propel it over the moon before returning to land. In subsequent missions further into the solar system (to asteroids and Mars), the liquid oxygen/liquid hydrogen ICPS will be replaced by more powerful superiors.
This stage was built by Boeing and is based on the cryogenic second stage used in the Delta IV rocket. Tereza Pultarova
A large amount of Saharan dust crosses the Atlantic Ocean
In images taken by NASA’s Earth Observation Satellite, a large amount of Saharan dust can be seen crossing the Atlantic Ocean.
In early June, a large column of Saharan dust caused by strong West African winds was moving across the Atlantic Ocean toward Florida, as shown in this image taken by the NASANOAA Suomi NPP satellite. Dust storm
occurred a year after the Sahara’s largest dust cloud in 20 years hit the Caribbean Sea, darkening the skies of several states in the southeastern United States. At the time, sensors on NASA’s Earth-observing satellite measured record concentrations of dust in the atmosphere.
The transport of dust from the African desert to the Americas is done regularly. Every year, more than 180 million tons of Saharan dust cross the Atlantic Ocean. However, NASA said in a blog post that the size of the pen in the past two years has been very special.
Some researchers predict that as climate change progresses, sand and dust storms will intensify, because higher temperatures can produce more dust. However, others believe that rising ocean temperatures and changes in wind speed can cause more precipitation in desert areas, thereby reducing dust. Teresa Pultarova
