Tech giant Amazon is adding a fifth rocket to launch its satellite internet constellation. In a surprise move on Friday afternoon, the company announced it purchased three flights aboard SpaceX’s Falcon 9 rockets to send batched of its Project Kuiper satellites to low Earth orbit.

On 1 December 2023, at 19:19 CET (18:18 GMT), Ireland's first satellite EIRSAT-1 launched from Vandenberg Space Force Base in California, USA.

Kicking off the month of December for SpaceX was a Falcon 9 ride share mission with a payload of 25 spacecraft on board. The launch from Vandenberg Space Force Base was headlined by the Korea 425 mission.

These moonless evenings open up the deep sky. For many of us the viewing is especially crisp through the low-humidity December air. The Big Dipper lies low, Cassiopeia stands high, and the Andromeda Galaxy crosses the zenith.

This month’s Sky Tour podcast introduces you to a “tower of brilliance” in the eastern evening sky, along with tips for finding four planets and watching mid-December’s impressive Geminid meteor shower.
Universe Today recently examined the potential for sending humans to the planet Venus despite its extremely harsh surface conditions. But while a human mission to the clouds of Venus could be feasible given the environmental conditions are much more Earth-like, a human mission to the second planet from the Sun could be (at minimum) decades away. With NASA sending humans back to the Moon in the next few years, and hopefully to Mars, what if we could send humans to another planetary body worth exploring, though it could have its own harsh environmental conditions, as well? What about Jupiter’s icy moon, Europa? It has a massive interior liquid ocean that could harbor life, and NASA is currently scheduled to launch its Europa Clipper spacecraft to this small moon in October 2024, arriving at Jupiter in April 2030. Therefore, given the exploration potential, should we send humans to Europa?
With NASA gearing up to send humans back to the Moon in the next few years with the Artemis missions with the goal of establishing a permanent outpost at the lunar south pole, nations are making efforts to contribute to Artemis and a permanent presence on our nearest celestial neighbor. Recently, the Italian Space Agency, formally known as Agenzia Spaziale Italiana (ASI), has taken steps to establish the first permanent outpost on the lunar surface, known simply as the Multi-Purpose Habitat (MPH). This endeavor was officially kicked by the ASI signing a contract with the French-based aerospace company, Thales Alenia Space, who specializes in space-based systems, including ground segments and satellites used for both Earth observation and space exploration.
The rich flow of scientific data—and stunning images—that comes from the Hubble Space Telescope is being interrupted by gyro problems. One of the telescope’s three remaining gyros gave faulty readings, and the Hubble automatically entered safe mode. In safe mode, science operations are suspended.
Pulsars are extreme objects. They’re what’s left over when a massive star collapses on itself and explodes as a supernova. This creates a neutron star. Neutron stars spin, and some of them emit radiation. When they emit radiation from their poles that we can see, we call them pulsars.
In June 2008, the Gamma-ray Large Area Space Telescope began surveying the cosmos to study some of the most energetic phenomena in the Universe. Shortly after that, NASA renamed the observatory in the Fermi Gamma-ray Space Telescope in honor of Professor Enrico Fermi (1901-1954), a pioneer in high-energy physics. During its mission, Fermi has addressed questions regarding some of the most mysterious and energetic phenomena in the Universe – like gamma-ray bursts (GRBs), cosmic rays, and extremely dense stellar remnants like pulsars.

Lengthy delays for the debut of Europe’s future flagship rocket may have an end in sight. During a briefing with press on Thursday, European Space Agency Director General Josef Aschbacher announced that Ariane 6 would have its first launch between mid-June and the end of July in 2024.
When the Vera C. Rubin Observatory comes online in 2025, it will be one of the most powerful tools available to astronomers, capturing huge portions of the sky every night with its 8.4-meter mirror and 3.2-gigapixel camera. Each image will be analyzed within 60 seconds, alerting astronomers to transient events like supernovae. An incredible five petabytes (5,000 terabytes) of new raw images will be recorded each year and made available for astronomers to study.
Astronomers have uncovered six sub-Neptune exoplanets dancing in lock-step around the same distant star, shedding light on their formation.

Almost 200 countries are gathering in Dubai to attend the biggest climate event of the year. COP28 – the 2023 United Nations climate change summit – isn’t just another conference though. For the first time, country representatives will assess the progress they’ve made towards cutting their greenhouse gas emissions through a process called the ‘global stocktake’.
Mary Cleave, who launched twice on the space shuttle before becoming the first woman to head NASA's science division, has died. Cleave was the 10th woman to fly in space and spent 11 days in orbit.
The Hubble Space Telescope has entered an automatic safe mode due to gyroscope difficulties, but scientists aren't worried about the observatory's health.
A 'Cannibal' plasma eruption from the sun will hit Earth on Dec. 1. Scientists predict strong geomagnetic storm conditions and impressive auroras.
