OneWeb Launches 34 Satellites into Orbit

British-based firm OneWeb launched 34 satellites into orbit from a cosmodrome in Kazakhstan, expanding its in-orbit constellation to 322 satellites.
The satellites lifted off from Kazakhstan's Baikonur cosmodrome.
OneWeb plans to launch a total of 648 low earth orbit satellites to roll out a high-speed global internet connection including to the most remote corners of the world.

SpaceX Makes History, Sends First All-civilian Crew into Earth Orbit

SpaceX's first private flight blasted off with two contest winners, a health care worker and their rich sponsor, the most ambitious leap yet in space tourism.
It was the first time a rocket streaked toward orbit with an all-amateur crew, no professional astronauts. The Dragon capsule's two men and two women are looking to spend three days circling the world from an unusually high orbit, 100 miles (160 kilometers) higher than the International Space Station, before splashing down off the Florida coast this weekend.

ISRO's New Series of Heavy-lift Rockets

To attain total self-reliance in the launch of heavy satellites (weighing above 4 tons) and to meet future demands, the Indian Space Research Organization (ISRO) is working on a fleet of five new rockets. According to a senior official, the five Heavy-lift Launch Vehicles (HLV) are in their project report stage and in terms of design and appearance, these new fleet of rockets would be quite similar to the existing SSLV, PSLV and GSLV and GSLV Mk3 rockets, but they would be powered by even more capable, powerful and technologically advanced engines.
Presently, India pays and utilizes the services of Ariane-5, a foreign rocket, to launch satellites that weigh over 4 tons.

Hughes, OneWeb Ink Pact for Low Earth Orbit Satellite Service

Hughes Network Systems and OneWeb have announced agreements for Low Earth Orbit satellite service in the US and India.
Hughes Network Systems focuses on satellite and multi-transport technologies and networks, and OneWeb is a Low Earth Orbit (LEO) satellite communications company backed by Bharti.
In India, the parties have entered into an MOU (Memorandum of Understanding) for a strategic agreement to distribute services to large enterprises, small and medium businesses, government, telcos and ISPs (Internet Service Providers) in the rural and remote parts of the country," said OneWeb.
Services will be offered by Hughes Network Systems, LLC, and Hughes Communications India, respectively.
Hughes and OneWeb would work together to broaden distribution globally, with Hughes offering OneWeb's low-latency, high-speed connectivity for markets such as enterprise, government, commercial aviation and maritime, cellular backhaul, and community Wi-Fi hotspots.

Hubble Finds Slowly Cooling White Dwarfs

Using high-resolution observational of two very similar globular clusters, Messier 3 and Messier 13, astronomers have found an unexpected overabundance of bright white dwarfs in Messier 13. Theoretical models suggest that this overabundance is due to a slowing down of the cooling process in around 70% of the white dwarfs in Messier 13, caused by stable thermonuclear burning in their residual hydrogen-rich atmosphere.
White dwarfs are core remnants of low-mass stars that have concluded their thermonuclear activity.
All stars with masses below 8 solar masses, with a possible extension up to 11 solar masses, are expected to end their evolution as white dwarfs.

Chandrayaan-2 Completes 2 Years in Lunar Orbit

The Chairman of Indian Space Research Organisation K. Sivan inaugurated a Lunar Science Workshop 2021, to commemorate the completion of two years of operation of Chandrayaan-2 spacecraft around the lunar orbit.
Chandrayaan-2 data product and science documents were released by Sivan, also Secretary in the Department of Space (DoS), along with data from Chandrayaan-2 orbiter payloads.
The eight payloads onboard Chandrayaan-2 are conducting scientific observations of the moon by remote sensing and in-situ techniques.
