The blast has been named GRB 221009A is probably one of the brightest GRB ever detected according to Mirko Piersanti, lead author of the team publishing the results on the 14th of November. The nearest rival is ten times weaker. This GRB took place in a galaxy almost 2 billion light-years away, yet it still had enough energy to affect the Earth. ]]> https://spacewatch.global/2022/05/darpa-launch-ionosphere-insights-mission-to-improve-radio-transmissions/ Fri, 20 May 2022 07:00:25 +0000 https://spacewatch.global/?p=41075 The Defense Advanced Research Projects Agency (DARPA) is launching the Ouija program to provide new insights into high-frequency (HF) radio wave propagation in the ionosphere with the help of sensors on low-orbiting satellites.  HF radio transmissions are important to military systems across all domains including space, air, ground, and maritime.]]> https://spacewatch.global/2018/11/asia-pacific-space-cooperation-organisation-members-celebrate-tenth-anniversary/ Fri, 16 Nov 2018 06:00:18 +0000 https://spacewatch.global/?p=11362 As part of the 10th anniversary celebrations of the Asia-Pacific Space Cooperation Organisation (APSCO), China intends to promote satellite imagery sharing with other member states for applications such as urban planning, disaster monitoring and assessment, as well as resource management and surveying.]]>
