ESA Announces Orbiter to Study Venus

European Space Agency (ESA) has announced about its probe called 'EnVision' to study Venus, after American Space agency NASA decided to send two missions to the planet.
EnVision will be the next orbiter to circle over Venus. It will provide a holistic view of planet from its inner core to upper atmosphere.
It will determine how and why Venus and Earth evolved so differently, even though they lie in habitable zone to the Sun as opposed to Nasa probes DAVINCI+ and VERITAS which will enter into atmosphere of Venus.
ESA will launch its probe by 2030.
Orbiter EnVision will be loaded with a sounder which will study underground layering, and spectrometer which will study atmosphere & surface. Spectrometers will monitor trace gases in atmosphere and analyse surface composition and look for any changes which could be linked to signs of active volcanism. A radio science experiment on orbiter will probe internal structure and gravity field of planet.

Verizon Brings Commercially Available Private 5G Network in US

Verizon Business launched its first commercially available private 5G network in the US to offer businesses and government departments' high-speed indoor or outdoor connectivity.
Private 5G networks remove the need for businesses to jostle for speed with others on a public network and help enable data-intensive applications that use computer vision, augmented reality and machine learning to increase productivity.
Verizon has been trialing private 5G with several customers and has partnered with the likes of Microsoft and Amazon.
The private 5G network, managed by Verizon, would keep all cellular traffic on the premises of the customer to increase security, while authorised remote users can still access applications.

Nigerian Government Joins Koo

Less than a week after banning American microblogging site Twitter indefinitely, the Nigerian government has joined its India-made rival Koo. Shortly after the ban, Koo had announced that it was available in Nigeria and was working to add local languages on its platform.
Nigeria's decision to suspend Twitter in the country reportedly came as a result of the US-based social networking platform deleting a tweet by President Muhammadu Buhari for violating rules. The Nigerian government had alleged that the microblogging site was being used to undermine Nigeria's corporate existence through the spreading of fake news that has violent consequences.

Scientists Create Exotic Outer Space Ice

Researchers from NASA's Jet Propulsion Laboratory and Oak Ridge National Laboratory successfully created amorphous ice, similar to ice in interstellar space and on icy worlds in our solar system. They documented that its disordered atomic behavior is unlike any ice on Earth.
The findings could help interpret data from future NASA missions such as Europa Clipper, which will assess the habitability of Jupiter's moon, Europa.
Using the Spallation Neutron Source's SNAP instrument, the scientists replicated the cold vacuum of space and added a few molecules at a time of heavy water to a plate cooled to 25 Kelvin to produce amorphous ice. They then used neutron scattering to observe the ice's structural changes at varying temperatures before it transitioned to crystalline ice.

SpaceX launches 22nd Resupply Services Mission to ISS

SpaceX has again launched its 22nd resupply services mission called SpaceX CRS 22, using cargo Dragon 2 capsule, to International Space station (ISS).
This is the second mission under new CRS contract of SpaceX with NASA and fifth capsule in last 12 months which SpaceX sent to ISS. The 22nd launch is also the first launch of 2021 on new Falcon 9 rocket booster. Falcon 9 Rocket launch vehicle is carried 7,300 pounds of research materials, supplies, hardware and new solar arrays. It is also carrying a number of research experiments which will be conducted on ISS. It carried a oral bacteria to test germ growth with Colgate toothpaste.
