The first Meteosat Third Generation Imager (MTG-I1) satellite lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana on 13 December at 21:30 CET.
From geostationary orbit, 36,000 km above the equator, this all-new weather satellite will provide state-of-the art observations of Earth’s atmosphere and realtime monitoring of lightning events, taking weather forecasting to the next level. The satellite carries two completely new instruments: Europe’s first Lightning Imager and a Flexible Combined Imager.
MTG-I1 is the first of six satellites that form the full MTG system, which will provide critical data for weather forecasting over the

Europe’s all-new weather satellite takes to the skies With success of Artemis I, when will NASA fly Artemis II?
Tuesday, 13 December 2022 17:10 Write a comment
With Orion safe back on Earth, the last and most important tests of the Artemis I mission have been completed, but there are still miles to travel and months of data sifting to go before NASA will target an Artemis II launch date.
While the latest announced timeline for that flight is no earlier than May 2024—only 18 months away—NASA officials after Sunday's successful landing kept referring a two-year turnaround between Artemis I and II, which would put its launch closer to the end of 2024.
"I think one thing we've always been concerned about is, what do we learn from [Artemis I] and are there changes we have to make? I think we've learned a lot," said Jim Free, NASA's associate administrator for the Exploration Systems Development Mission Directorate during a post-landing press conference Sunday.
"We obviously want to try to do it quicker," Free said, and pointed out the Orion team is "always looking to ways to do things quicker. We're trying to roll in lessons learned from the processing of the Artemis I vehicle at Kennedy. Are there things we can shorten there? Optimize? So that's all of our lessons learned path going forward.
US researchers announce historic nuclear fusion breakthrough

US researchers announced a historic nuclear fusion breakthrough on Tuesday, hailing a "landmark achievement" in the quest for a source of unlimited, clean power and an end to reliance on fossil fuels.
The Lawrence Livermore National Laboratory (LLNL) in California said an experiment it conducted this month "produced more energy from fusion than the laser energy used to drive it."
The US Sound of a dust devil on Mars recorded for first time

The sound of a dust devil on Mars was recorded for the first time as the eye of the whirlwind swept over the top of NASA's Perseverance rover, a new study said Tuesday.
"We hit the jackpot" when the rover's microphone picked up the noise made by the dust devil overhead, the study's lead author Naomi Murdoch told AFP.

NASA's Orion capsule, after traveling 1.4 million miles through space, including orbiting the moon and collecting data, returned to Earth on Sunday.
The 25 1/2-day Artemis I mission landed in the Pacific Ocean off Mexico's Baja California at 12:40 p.m., NASA reported.

Dark matter could be made up of ultralight dark photons that heated up our universe: this is a new scenario proposed in a study recently published in the scientific journal "Physical Review Letters". This hypothesis, the authors say, is in excellent agreement with observations made by the Cosmic Origin Spectrograph (COS) on board the Hubble Space Telescope, which takes measurements of the "cosmi FAST reveals unprecedented details of the Milky Way

Many bright stars gather in the night sky and form a Milky Way across the sky. It is our home galaxy in the vast universe, however, the structure and composition of the Milky Way are mysterious yet. The vast interstellar space between the billions of stars is not empty, but filled with tenuous interstellar medium.

The uncrewed Artemis I test flight saw Orion travel around the Moon and farther than any spacecraft designed to carry humans and return them to Earth. Artemis is the international lunar exploration programme that is taking humankind to the Moon. This first mission provided a first test of both NASA’s Space Launch System (SLS) and the Orion moonship that was propelled by the European Service Module’s 33 engines beyond the Moon and into deep space. Future European Service Modules will provide electricity, propulsion and cabin thermal control for astronauts on lunar missions as well as breathable atmosphere

With liftoff set for today at 21:30 CET, the Ariane 5 rocket carrying the first Meteosat Third Generation Imager, MTG-I1, satellite is poised patiently on the launch pad at Europe’s Spaceport in French Guiana while the final checks are being carried out. Once in geostationary orbit, 36,000 km above the equator, this new satellite is set to herald a new era for meteorology.
