A second pair of SES' O3b mPower satellites launched on a SpaceX rocket
A SpaceX Falcon 9 launched two communication satellites, O3b mPower 3 and 4, and is now just one launch away from launching SES' next-generation broadband constellation in medium Earth orbit (MEO).
Falcon 9 lifted off Florida's Cape Canaveral Space Force Station, Space Launch Complex-40 (SLC-40), at 6:12 p.m. EDT (2212 GMT) on Friday.
O3b is an acronym that stands for "Other 3 Billio What is the Fluidic Telescope?
The Fluidic Telescope (FLUTE) project team, jointly led by NASA and Technion–Israel Institute of Technology, envisions a way to make huge circular self-healing mirrors in-orbit to further the field of astronomy.
UAE astronaut exits ISS for first Arab space walk
Emirati astronaut Sultan Alneyadi stepped out of the International Space Station (ISS) Friday for the first space walk by an Arab astronaut, a moment touted by the UAE as a "milestone".
Alneyadi, 41, dubbed the "Sultan of Space" by his alma mater, become the first Arab astronaut to embark on a six-month space mission when he blasted off for the ISS in early March aboard a SpaceX Falcon 9 rocket.
On Friday, he undertook "the first Arab spacewalk in history," wearing a space suit that bears the Emirati flag, said the United Arab Emirates' Mohammed bin Rashid Space Centre (MBRSC), calling it "a new historic milestone".
Footage live-streamed by NASA showed the UAE astronaut exiting an ISS hatch.
"Sultan Alneyadi has egressed the hatch, the first ever space walk by an Arab astronaut," NASA said.
The space walk will last for around six hours and thirty minutes, according to MBRSC and NASA.
Alongside NASA's Stephen Bowen, Alneyadi will "change the Radio Frequency Group unit and prepare for the installation of solar panels," the Emirati astronaut said in a Twitter post carried by the official WAM news agency.
Work continues to deploy Juice RIME antenna
Juice’s ice-penetrating RIME antenna has not yet been deployed as planned. During the first week of commissioning, an issue arose with the 16-metre-long Radar for Icy Moons Exploration (RIME) antenna, which is preventing it from being released from its mounting bracket.

Raytheon unveils next-gen intelligent electro-optical sensing capability
Raytheon Technologies (NYSE: RTX) has announced the launch of RAIVEN, a revolutionary electro-optical intelligent-sensing capability, which will enable pilots to have faster and more precise threat identification.
RAIVEN can identify objects optically and spectrally simultaneously in real-time - a single electro-optical/infrared, or EO/IR, system has never been able to do this before. China to promote space science progress on five themes
China is planning to promote its space science development on five major themes, including research on habitable planets, and biological and physical sciences in space, a senior Chinese space expert said Tuesday.
China is making a national plan suggesting the deployment of more scientific satellites in the country's space program to yield leading breakthroughs globally on themes such as th Space exploration for betterment of humankind
Monday marked China's eighth Space Day, a day to celebrate the country's achievements in space exploration and research, and ponder how to carry forward the spirit of space exploration for the benefit of humankind.
China designated April 24 as Space Day in 2016 to mark the launch of the country's first satellite, Dongfanghong 1 on the same day in 1970.
As the backbone of the air spac China to develop satellite constellation for deep space exploration
China will develop a satellite constellation named Queqiao, or Magpie Bridge, to provide communications, navigation and remote-sensing services for deep space exploration, according to a senior Chinese space expert.
Speaking at the First International Deep Space Exploration Conference held in Hefei, the capital of east China's Anhui Province, Wu Yanhua, chief designer of the major project Pentagon leaks suggest China developing ways to attack satellites
The recent leak of Pentagon documents included the suggestion that China is developing sophisticated cyber attacks for the purpose of disrupting military communication satellites. While this is unconfirmed, it is certainly possible, as many sovereign nations and private companies have considered how to protect from signal interference.
