CONFUSION OVER CAUSE OF FLASH IN SKY OVER KYIV AFTER NASA DENIES INVOLVEMENT - A flash in the sky over the Ukrainian capital prompted confusion and alarm as city authorities said it was caused by a Nasa satellite reentering the atmosphere, while the US space agency denied involvement. A “bright glow” was observed over Kyiv around 10pm local time, the head of Kyiv’s military administration Sergiy Popko wrote on Telegram. An air raid alert was activated, Popko said, but “air defence was not in operation”. More (Source: The Guardian - Apr 20)
RUSSIAN COSMONAUTS RELOCATE RADIATOR ON INTERNATIONAL SPACE STATION SPACEWALK - Two Russian cosmonauts helped relocate a large radiator outside of the space station overnight, completing a spacewalk that had been twice delayed. International Space Station Expedition 69 commander Sergey Prokopyev and flight engineer Dmitry Petelin, both of Russia's federal space corporation Roscosmos, conducted a 7 hour, 55 minute EVA (extravehicular activity) overnight on Tuesday and Wednesday (April 18 to April 19) to relocate the radiator from one Russian module to another.

CHINA'S NEW SPACE STATION, TIANGONG, WILL RUN HIGH-ENERGY BEAM EXPERIMENTS - China has completed the remarkable feat of building and deploying its third space station, Tiangong, in a mere two years. Translated, Tiangong means "Palace in the Sky," and this new space station aims to test various technologies that could eventually be used on a larger scale, with both civilian and military applications. In addition to its scientific applications, Tiangong will be used as a testbed for China's future manned spaceflight program. More (Source: Forbes - Apr 19)

DEAD NASA SATELLITE WILL CRASH TO EARTH THIS WEEK - A dead NASA spacecraft will come crashing back to Earth in the next few days, experts say. NASA's RHESSI satellite, which studied the sun from 2002 until its decommissioning in 2018, is expected to reenter Earth's atmosphere around 9:30 p.m. EDT on Wednesday (April 19; 0130 GMT on April 20), plus or minus 16 hours, according to the latest estimates by the U.S. military. RHESSI (short for "Reuven Ramaty High Energy Solar Spectroscopic Imager") isn't a huge satellite. It weighs just 600 pounds (270 kilograms), and the majority of that mass will be converted to ash and vapor during RHESSI's death dive, NASA officials said. More (Source: Space.com - Apr 18)
NEXT-GENERATION SATELLITE NETWORK COULD CONNECT EARTH WITH BASES ON MOON'S FAR SIDE - As NASA's cargo and crew programs for the International Space Station increasingly look to commercial providers for launch services, other sectors of the space agency are increasingly looking to private companies to add critical infrastructure to support NASA missions. To that end, Lockheed Martin has created Crescent Space Services LLC, a subsidiary aimed at operating a service-based network of communication and navigation satellites to support future missions to the moon, the company announced.
