PASADENA, Calif. (NASA PR) — Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.
Europa has long been a high priority for exploration because beneath its icy crust lies a salty, liquid water ocean. NASA’s Europa Clipper, targeted to launch in 2022, will be equipped with the instruments necessary to determine whether Europa possesses the ingredients necessary to support life as we know it.
Lori Glaze, acting director of NASA’s Planetary Science Division (PSD), and JoAnna Wendel, PSD communications lead, will host the chat. Guests include:
Xianzhe Jia, associate professor in the Department of Climate and Space Sciences and Engineering at the University of Michigan, Ann Arbor
Elizabeth Turtle, research scientist at Johns Hopkins Applied Physics Laboratory in Laurel, Maryland
Margaret Kivelson, professor emerita of Space Physics in the Department of Earth and Space Sciences at the University of California, Los Angeles
The public can send questions on social media by using #askNASA at any time during the event.
The Science Chat will occur as the scientific journal Nature Astronomy publishes a paper about how NASA’s Galileo spacecraft flew through a plumb of water from Europa a thousand kilometers (620 miles) thick. News of the paper had been embargoed by the journal, but Rep. John Culberson (R-Texas) revealed the finding during a subcommittee hearing last week.
SWINDON, UK (UKSA PR) — The UK Government has confirmed today it is developing options for a British Global Navigation Satellite System.
Led by the UK Space Agency, a task force of Government specialists and industry will work quickly to develop options that will provide both civilian and encrypted signals and be compatible with the GPS system.
The UK is already a world-leader in developing satellite technology, building 40 per cent of the world’s small satellites and one in four commercial telecommunications satellites.
UK companies have made a critical contribution to the EU Galileo programme, building the payloads for the satellites and developing security systems. The task force will draw on this experience and expertise as it develops plans for an innovative system that could deliver on the UK’s security needs and provide commercial services.
EVRY, France 9 (Arianespace PR) — The past year saw Arianespace carry out 11 successful launches; sign 19 additional launch contracts, including three for Vega C and two for Ariane 6; and enter a new governance structure alongside ArianeGroup.
Building on these achievements, Arianespace is targeting a record number of launches in 2018, while actively focusing on the next decade with its Ariane 6 and Vega C launchers. (more…)
KOUROU, French Guiana (Arianespace PR) — Arianespace has successfully launched satellites 19, 20, 21 and 22 in the Galileo constellation, using an Ariane 5 heavy launcher on behalf of the European Commission (DG GROW) and under a contract with the European Space Agency (ESA).
The launch took place on December 12, 2017 at 3:36 p.m. (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana. (more…)
We’ve got a busy launch week coming up with a new three-man crew headed for the International Space Station (ISS), SpaceX launching a Dragon resupply mission to the station, and Rocket Lab attempting the second flight test of its Electron small-satellite launcher. Europe and China are also launching satellites this week.

PARIS, 15 September 2017 (ESA PR) — Four of the latest set of Galileo navigation satellites will be launched on Ariane 6 rockets – ESA’s first contract to use Europe’s new vehicle.
The launches are scheduled between the end of 2020 and mid-2021, using two Ariane 62 rockets – the configuration of Europe’s next-generation launch vehicle that is best suited to haul the two 750 kg navigation satellites into their orbits at 23 222 km altitude.

PARIS (Arianespace PR) — Arianespace is targeting another busy year of activity in 2016 – continuing its launch services excellence by performing up to 11 missions utilizing Ariane 5, Soyuz and Vega, while reinforcing its international marketplace competitiveness with commercial offers that combine the company’s attributes of reliability, availability and price.
Russia continued its dominance of the global satellite launch industry in 2015, conducting 29 of 86 orbital launches over the past 12 months. It also maintained its lead in botched launches, suffering two failures and one partial failure.
Video Caption: 2015 began and ended with two pioneering missions: IXV, the Intermediate Experimental Vehicle, proving Europe’s ability to return autonomously from space, and LISA Pathfinder, which set out in December to test the technologies needed to detect gravitational waves and, with them, a new way to look at our Universe! But a lot has happened in between… More European astronauts have visited space and more satellites are beefing up Galileo and ESA’s Earth Observation programme!
PARIS (Arianespace PR) — With 12 successful launches over 12 months, Arianespace’s mission performance in 2015 was one for the record book – concluding with today’s Soyuz flight that further expanded the European Galileo global navigation satellite system.
That’s the Russian space program’s sad record since May 2009. The failure of a Proton rocket earlier today with the loss of a Mexican communications satellite was yet another sign of the prolonged crisis affecting Russia’s once powerful space program.
The crash came less than three weeks after a botched launch left a Progress supply freighter spinning end over end like an extra point before it burned up in Earth atmosphere. There was also news today that another Progress cargo ship attached to the International Space Station failed to fire its engine as planned to boost the station’s orbit.
The list of Russian launch accidents over the last six years includes:
13 complete failures resulting in the loss of all payloads;
3 partial failures that left spacecraft in the wrong orbits;
