Access to space is getting easier and more accessible as more and more platforms are coming online that can significantly decrease the cost of getting into Earth's orbit or even beyond. Now, another company has taken a step forward in making inexpensive, reusable access to space a reality. Dawn Aerospace, which operates out of the U.S., New Zealand, and the Netherlands, has successfully tested a prototype spaceplane.
This isn't Dawn's first success, as the company already has satellite propulsion systems in orbit on 15 different satellites. It isn't even its first successful space plane test—they had previously completed some testing using jet engines. However, it is the first time the company has successfully tested a rocket-powered plane.
The series of three tests happened at the end of March at the Glentanner Aerodrome in New Zealand, where the plane successfully fired its rocket engine. Clocking it at over 170 knots and 6,000 ft of altitude may not seem like much, but it is a first step for the technology.
Wobbling star found in Gaia-Hipparcos data confirmed to host exoplanet
Thursday, 13 April 2023 18:12 Write a comment
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.

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.

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". 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.

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."

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.

Europe's JUICE mission to launch for Jupiter's icy moons
Thursday, 13 April 2023 07:16 Write a comment
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.

Weather delays launch of Europe's Jupiter mission by 24 hours (Update)

The launch of the European Space Agency's JUICE mission, which aims to discover whether Jupiter's icy moons are capable of hosting extraterrestrial life, was postponed on Thursday for 24 hours due to bad weather.
The launch was called off just minutes before the planned lift-off at 1215 GMT from Europe's spaceport in Kourou, French Guiana, because of the threat of lightning in the cloudy skies overhead.
The next attempt will take place at 1214 GMT on Friday, the European Space Agency said.
Stephane Israel, the CEO of French firm Arianespace which provided the Ariane 5 rocket, said that with just minutes to spare, "a large mass of clouds approached and we absolutely could not proceed with the launch due to the risk of lightning".
For lift-off to go ahead, three parameters must get the green light: the launcher, the probe and the weather—which was "the final suspense," he told AFP.
