Wobbling star found in Gaia-Hipparcos data confirmed to host exoplanet
Data from ESA’s star-mapping Gaia spacecraft has allowed astronomers to image a gigantic exoplanet using Japan's Subaru Telescope. This world is the first confirmed exoplanet found by Gaia’s ability to sense the gravitational tug or ‘wobble’ a planet induces on its star. And the technique points the way to the future of direct exoplanet imaging.
Launch of Europe's JUICE spacecraft postponed to Friday (Update)
The European Space Agency's JUICE spacecraft is to blast off Thursday on an eight-year journey through the Solar System to discover whether Jupiter's icy moons are capable of hosting extraterrestrial life in their vast, hidden oceans.
The JUpiter ICy Moons Explorer (JUICE) has received the green light for its scheduled launch on an Ariane 5 rocket from Europe's spaceport in Kourou, French Guiana at 1215 GMT.
"The weather conditions are good," Guiana Space Center director Marie-Anne Clair said on Wednesday in the control room, where Belgium's King Philippe was among those in attendance.
The six-tonne spacecraft, which is roughly four square meters, will separate from the rocket at an altitude of 1,500 kilometers (930 miles) a little under half an hour after blast-off.

Waking up Juice

It takes a while for a new mission to wake up after the rigours of launch, but before it’s fully in flight configuration it’s still exposed to the harsh realities of space. During this critical period, known as the ‘Launch and Early Orbit Phase’ or ‘LEOP’, teams at ESA’s mission control in Darmstadt, Germany, have to work fast to establish contact with the fledgling mission, and ensure its solar arrays are correctly powering the mission.
Once ESA’s Jupiter Icy Moons Explorer, Juice, separates from its Ariane 5 rocket, there will be two key moments to look out for.
Taiwan seeks satellite solutions after undersea cables cut
Taiwanese hostel worker Wang Chuang-jen's business took a hammering when undersea telecoms lines serving tiny Matsu archipelago were cut in February.
"It was very inconvenient," said the 35-year-old from Matsu's Beigan island, where customers struggled to book or pay online due to slow connectivity. "We all heavily depend on the internet."
The cut-off not only caused headaches for busine Slip and Pivot: Sol 3797
As you can see in the above image, the terrain our rover drivers is navigating is challenging - slippery sand surrounding big, wheel-unfriendly rocks. These contrasting regimes contributed to us not-quite-arriving at our planned workspace with all six wheels confidently on known terrain.
Thus, we had to pivot from a combined contact and remote science day, to one with remote science and a China bans ships from area north of Taiwan Sunday due to 'falling rocket wreckage'
China will ban ships from entering an area north of Taiwan on Sunday due to "possible falling rocket wreckage", a provincial maritime authority said.
The area around 100 miles (160 kilometres) from Taipei will be closed from 9 am (0100 GMT) to 3 pm (0700 GMT), the maritime safety administration of China's eastern Fujian province said Thursday, adding that ships will be "forbidden to enter".

Juice – Jupiter Icy moons Explorer – is humankind’s next bold mission to the outer Solar System. This ambitious mission will characterise Ganymede, Callisto and Europa with a powerful suite of remote sensing, geophysical and in situ instruments to discover more about these compelling destinations as potential habitats for past or present life. Juice will monitor Jupiter’s complex magnetic, radiation and plasma environment in depth and its interplay with the moons, studying the Jupiter system as an archetype for gas giant systems across the Universe.
Following launch, Juice will
Chinese FY-3 satellites enrich global soil moisture dataset
Surface soil moisture (SSM) plays an important role in drought and flood monitoring, weather forecasting, among other natural resource activities, and is also critical in water and heat exchanges between land and atmosphere.
SSM can be measured by instruments in the field or by remote sensing techniques. Satellite observations from active and passive microwave sensors are best suited for t Rocket Lab to launch NASA's cyclone-tracking satellite constellation from New Zealand
Rocket Lab USA, Inc. (Nasdaq: RKLB) will launch NASA's TROPICS constellation across two dedicated Electron missions lifting off from Launch Complex 1 in New Zealand next month.
The TROPICS constellation (Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of Small Sats) will monitor the formation and evolution of tropical cyclones, including hurri
