Hubble finds evidence of persistent water vapor in one hemisphere of Europa
This photograph of the Jovian moon Europa was taken in June 1997 at a range of 776,700 miles by NASA's Galileo spacecraft. Slightly smaller than Earth's moon, Europa has a very smooth surface and the solid ice crust has the appearance of a cracked eggshell. The interior has a global ocean with more water than found on Earth. It could possibly harbor life as we know it. Hubble Space Telescope observations of Europa have revealed the presence of persistent water vapor in its very tenuous atmosphere. Hubble observations, spanning 1999 to 2015, find that water vapor is constantly being replenished throughout one hemisphere of the moon. This is a different finding from Hubble's 2013 observations that found localized water vapor from geysers venting from its subsurface ocean. This water vapor comes from a different process entirely. Sunlight causes the surface ice to sublimate, transitioning directly into gas. This color composite Galileo view combines violet, green, and infrared images. The view of the moon is shown in natural color (left) and in enhanced color designed to bring out subtle color differences in the surface (right). The bright white and bluish part of Europa's surface is composed mostly of water ice, with very few non-ice materials.

A Russian Soyuz rocket on Thursday blasted into space carrying 36 new satellites from British operator OneWeb, which aims to provide broadband internet everywhere in the world.

The rocket, operated by Europe's Arianespace, took off at 0940 GMT from the Vostochny cosmodrome in Russia's Far East, broadcast live by the country's Roscosmos space agency.

"LIFTOFF!" Roscosmos tweeted after the launch—the seventh this year carrying OneWeb satellites.

OneWeb, a London-headquartered company, is working to complete the construction of a constellation of low earth orbit satellites providing enhanced broadband and other services to countries around the world.

The company is competing in the race to provide fast internet for the world's remote areas via satellites along with tech billionaire Elon Musk and fellow billionaire Jeff Bezos of Amazon.

The UK company plans for its global commercial internet service to be operational by next year, supported by some 650 satellites.

Arianespace, which has worked with Russia for close to two decades, is under contract to make 16 Soyuz launches between December 2020 and the end of 2022.

With this latest mission, a total of 358 satellites are now in orbit for the constellation, Roscosmos said.

How can a digital replica of Earth help us understand our planet’s past, present and future? As part of the fourth edition of Φ-week taking place this week, a group of European scientists have put forward their ideas on the practical implementation of Digital Twins and the potential application areas for a Digital Twin Earth in the real world.

Britain's Prince William visits a London school to promote the 'Generation Earthshot' educational initiative
Britain's Prince William visits a London school to promote the 'Generation Earthshot' educational initiative.

Britain's Prince William has launched an attack on space tourism, urging more attention on problems closer to home ahead of the COP26 climate summit.

The comments by Queen Elizabeth II's grandson were airing in a BBC interview later Thursday, a day after "Star Trek" star William Shatner became a real space traveller on Blue Origin's second crewed mission.

The mission replayed the company's maiden human flight in July, which included its founder Jeff Bezos of Amazon and was seen as a breakthrough for the emerging sector.

But Prince William said: "We need some of the world's greatest brains and minds fixed on trying to repair this planet, not trying to find the next place to go and live."

Virgin Galactic, which offers a similar experience of a few minutes' weightlessness and a view of the Earth's curvature from the cosmos, launched its founder Richard Branson in July, a few days before Bezos.

NASA turns to the cloud for help with next-generation Earth missions
The state-of-the-art Earth science satellites launching in the near future will be generating unprecedented quantities of data on our planet’s vital signs. Cloud computing will help researchers make the most of those troves of information. Credit: NASA Earth Observatory

As satellites collect larger and larger amounts of data, engineers and researchers are implementing solutions to manage these huge increases.

The cutting-edge Earth science satellites launching in the next couple of years will give more detailed views of our planet than ever before. We'll be able to track small-scale ocean features like coastal currents that move nutrients vital to marine food webs, monitor how much fresh water flows through lakes and rivers, and spot movement in Earth's surface of less than half an inch (a centimeter).
