For the first time ever, a telecommunications satellite has used an iodine propellant to change its orbit around Earth.

The small but potentially disruptive innovation could help to clear the skies of space junk, by enabling tiny satellites to self-destruct cheaply and easily at the end of their missions, by steering themselves into the atmosphere where they would burn up.

For the first time, scientists have successfully used satellite cameras coupled with deep learning to count animals in complex geographical landscapes, taking conservationists an important step forward in monitoring populations of endangered species. For this research, the satellite Worldview 3 used high-resolution imagery to capture African elephants moving through forests and grasslands.

Aboard Yuanwang-5 (Xinhua) Jan 22, 2021
China's space tracking ship Yuanwang-5 completed its mission in the Pacific Ocean to monitor and ensure the launch of the Tiantong 1-03 satellite on Wednesday. China successfully launched the mobile telecommunication satellite at 12:25 a.m. (Beijing Time) on Wednesday. The satellite entered its planned orbit. As the only maritime monitoring site for the launch, Yuanwang-5 was respons

A group of international scientists, including an Australian astrophysicist, has used knowhow from gravitational wave astronomy (used to find black holes in space) to study ancient marine fossils as a predictor of climate change. The research, published in the journal Climate of the Past, is a unique collaboration between palaeontologists, astrophysicists and mathematicians - to improve th

This week the European Commission has awarded two contracts for 12 Satellites (6 satellites each) for a total of EUR euro 1.47 billion, to ThalesAleniaSpace (Italy) and Airbus Defence and Space (Germany) following an open competition. With this, the Commission is initiating the launch of the 2nd Generation of Galileo, the European satellite positioning system. The aim is to keep Galileo a

China's first solar probe, Advanced Space-based Solar Observatory (ASO-S), is scheduled to be launched into space in the first half of 2022, marking the country's first-ever mission to "touch" the sun. The satellite will operate in a sun-synchronous orbit 720 km above Earth to keep a close tab on the sun 24 hours a day. Measuring about 1,000 kg in total mass, the satellite is expected to o

Oxford UK (SPX) Jan 22, 2021
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System. Their findings will be published in Science (Friday 22 January 2021; under embar

This composite image shows a hot spot in Jupiter's atmosphere. In the image on the left, taken on Sept. 16, 2020 by the Gemini North Telescope, the hot spot appears bright in the infrared at a wavelength of 5 microns. The inset image on the right was taken by the JunoCam visible-light imager aboard NASA's Juno spacecraft, also on Sept. 16, during Juno's 29th close pass by Jupiter. Here, th
