Russia launches new batch of UK telecom satellites into space
Monday, 26 April 2021 06:56A Soyuz rocket blasted off from the Vostochny cosmodrome in Russia's Far East on Monday carrying 36 UK telecommunications and internet satellites, the Roscosmos space agency said.
OneWeb, a London-headquartered company, is working to complete the construction of a constellation of low earth orbit satellites providing enhanced broadband and other services to countries around the world.
The company is competing against billionaires Elon Musk and Jeff Bezos in the race to provide fast internet via satellites for the world's remote areas.
Images released by Russia's space agency Roscosmos showed the Soyuz rocket taking off against hazy skies Monday morning at 7:14 am local time (2214 GMT).
"All satellites have been successfully placed in target orbits and have been taken under customer control," Roscosmos said in a statement.
"Mission success!" OneWeb wrote on Twitter.
The UK company plans for its global commercial internet service to be operational by next year, supported by some 650 satellites.
Monday's launch was the third batch of its satellites placed into orbit from Russia, with earlier launches from the Vostochny cosmodrome of 36 satellites each taking place last month and in December.
OneWeb's first six satellites were also launched by a Russian-made Soyuz rocket, taking off from the space centre in Kourou in French Guiana in February 2019.
ESA to live tweet asteroid impact exercise

For almost a decade, world asteroid experts have been meeting every two years at the Planetary Defense Conference and pretending an asteroid impact is imminent. Why? To prepare for the unlikely – but plausible – scenario in which this comes true.
OneWeb adds 36 satellites to broadband constellation as deployment accelerates
Sunday, 25 April 2021 21:32
TAMPA, Fla. — OneWeb’s growing low Earth orbit broadband constellation is set to reach 182 satellites, after Arianespace launched its latest batch of 36 spacecraft April 25.
Arianespace launched the satellites with a Soyuz-2.1b rocket that blasted off 6:14 p.m.
U.S. military’s appetite for information fueling demand for space technology
Sunday, 25 April 2021 20:13
WASHINGTON — The U.S. Army last week announced plans to explore new uses of satellites and other space technology in support of soldiers on the ground.
This is a clear sign that the demand for space-based capabilities is growing across the U.S.
NASA's Mars helicopter's third flight goes farther, faster than before
Sunday, 25 April 2021 18:24
NASA's mini helicopter Ingenuity on Sunday successfully completed its third flight on Mars, moving farther and faster than ever before, with a peak speed of 6.6 feet per second.
After two initial flights during which the craft hovered above the Red Planet's surface, the helicopter on this third flight covered 64 feet (50 meters) of distance, reaching the speed of 6.6 feet per second (two meters per second), or four miles per hour in this latest flight.
"Today's flight was what we planned for, and yet it was nothing short of amazing," said Dave Lavery, the Ingenuity project's program executive.

China has experienced an explosion of commercial space companies since 2014, driven by the government opening up the space sector to private capital.
According to Chinese publication Future Aerospace, there were 141 registered commercial aerospace companies in China by the end of 2018, in areas including launch, propulsion, satellite manufacturing, payloads and applications and ground stations.
SpaceX Crew-2 astronauts enter International Space Station
Sunday, 25 April 2021 08:07
The four astronauts aboard Crew-2 Dragon capsule Endeavour entered the International Space Station on Saturday morning, more than 26 hours after being launched from Florida.
The arrival boosted space station occupancy temporarily to 11, one of the highest numbers in history and the most since the space shuttle program ended in 2011. The record was set in 2009 with 13 people on board. Georgia Tech shares $15M from NASA to advance deep space exploration

Every few years, NASA creates Space Technology Research Institutes (STRI) in areas it believes are going to be strategic for future technology and space missions. Today, that area is electric propulsion - the use of electrical energy to accelerate propellant to create thrust. The technology yields extremely efficient thrusters to power space flight for gateway launches to the moon or even shuttl Stone skipping techniques can improve reentry of space vehicles
