Eyes on Hera: Asteroid mission’s cameras ready
Thursday, 23 February 2023 12:15
ESA’s Hera asteroid mission for planetary defence is about to gain its sight. Two complete and fully tested Asteroid Framing Cameras have reached OHB in Germany for integration aboard Hera’s payload module. This instrument will provide the very first star-like view of Hera’s target for the mission to steer towards the Dimorphos asteroid, which last year had its orbit altered by an impact with NASA’s DART mission.
ESA’s forest satellite robust for launch
Thursday, 23 February 2023 12:00
Over the last few months, ESA’s Earth Explorer Biomass satellite has been going through a punishing series of tests to make sure that it will survive the unavoidable blasts of noise and shuddering during liftoff. Engineers have now also tested that it will unfold its solar wing in the correct sequence. Coming through all of this with flying colours, Biomass is a few steps closer to its mission in orbit: to deliver completely new information on our precious forests and the carbon they store.
The ozone layer: a hole new world

In the 1980s, scientists discovered a gaping hole in Earth's ozone layer, caused by humanmade chemicals. But thanks to the historical Montreal Protocol, the world came together to take bold action to save our planet. Decades later, we can see the steady recovery of the ozone hole. How did we do it? And what does space have to do with it? Join us as we explore the journey of the ozone hole, from its alarming discovery to the incredible strides made to fix it, and how satellites are helping us track its recovery.
NASA to launch Israel's first space telescope
Thursday, 23 February 2023 10:38
NASA will launch Israel's first space telescope mission, the Ultraviolet Transient Astronomy Satellite (ULTRASAT). ULTRASAT, an ultraviolet observatory with a large field of view, will investigate the secrets of short-duration events in the universe, such as supernova explosions and mergers of neutron stars.
Led by the Israel Space Agency and Weizmann Institute of Science, ULTRASAT is plan Luojia-3 01 satellite completes key technical tests
Thursday, 23 February 2023 10:38
The Luojia-3 01 satellite has completed several technical tests, and its multi-mode intelligent remote sensing service capability has reached the expected target, according to Wuhan University.
Luojia-3 01 is an internet-intelligent remote-sensing scientific experiment satellite, mainly developed by Wuhan University and launched by a Long March-2D rocket on Jan. 15.

Thursday, 23 February 2023 04:31
NASA and SpaceX announced that its manned Crew-6 flight scheduled to liftoff from the Kennedy Space Center on Sunday has been delayed 24 hours so engineers can work their way through what has been described as "minor issues."
SpaceX's capsule Endeavour was scheduled to launch on a Falcon 9 rocket Sunday evening. After a flight readiness review briefing on Tuesday afternoon, it was decid World's first 3D-printed rocket Terran 1 is ready for its maiden flight
Thursday, 23 February 2023 04:31
Relativity Space announced on Twitter that their expendable Terran 1 rocket has secured a launch license and is targeting liftoff on March 8 from Space Launch Complex 16 (SLC-16), Cape Canaveral Space Force Station (CCSFS), Florida. The launch window is between 1:00-4:00 p.m. ET (1800-2100 GMT).
The 110-foot (33-meter) Terran 1 will undergo a crucial launch test on the "Good Luck, Have Fun Meteorite crater discovered in French winery
Thursday, 23 February 2023 04:31
Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite.
Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long Water rich asteroids came from far outside the asteroid belt
Thursday, 23 February 2023 04:31
Where did the water that makes up Earth's oceans come from? This question has not yet been definitively answered. When Earth was formed, 4.5 billion years ago, it received a quantity of volatile substances from the primordial solar nebula, which were outgassed from the interior of the young planet during the solidification of an early magma ocean and through active volcanism.

Thursday, 23 February 2023 04:31
A team of astronomers led by Carnegie's Shubham Kanodia has discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings which are published in The Astronomical Journal, challenge long-held ideas about planet formation.
Smaller and cooler than our Sun, M dwarfs are the most common stars in our Milky Way galaxy. Due t CARMENES project boosts the number of known planets in the solar neighbourhood
Thursday, 23 February 2023 04:31
The CARMENES program, led by a consortium of Spanish and German research institutions, in which the Max Planck Institute for Astronomy (MPIA) is a partner, has released 20,000 observations of more than 300 stars. These measurements led to the discovery of 59 planets, with a dozen being potentially habitable. This spectroscopic data set was obtained at the Calar Alto Observatory in Spain and is n
