On they march as China records 401st flight of Long March rocket family
China launched a relay satellite from the Xichang Satellite Launch Center in southwestern China early on Tuesday morning, according to China Aerospace Science and Technology Corp, the nation's major space contractor.
A Long March 3B carrier rocket blasted off at 0:09 am and then deployed the Tianlian II-02 satellite into orbit, the State-owned company said in a statement. The mission marke Deadliest period in Earth's history was also the stinkiest
Tiny microbes belching toxic gas helped cause - and prolong - the biggest mass extinction in Earth's history, a new study suggests. Generally, scientists believe Siberian volcanos spitting greenhouse gases primarily drove the mass extinction event about 250 million years ago, at the end of the Permian period. The gases caused extreme warming, which in turn led 80% of all marine species, as well L3Harris Completes Delivery of Imagers for NOAA's Advanced Environmental Satellites
L3Harris Technologies has delivered its fourth imager to NASA, completing the series of advanced weather sensors for NOAA's newest Geostationary Operational Environmental Satellites (GOES) and lays the groundwork for future imager programs.
The fourth Advanced Baseline Imager (ABI) will be integrated into the GOES-U satellite, slated to launch in 2024, and will be operated by NOAA.
T DARPA Announces Forecasting Floats in Turbulence Challenge Winners
The mystery of knowing where the proverbial message in a bottle thrown overboard in the open sea will eventually wash ashore has not been solved. But DARPA's recent Forecasting Floats in Turbulence (FFT) challenge took an exploratory first step toward trying to understand the turbulent convergence of wind, waves, and currents on the surface of the ocean - and its effect on objects floating at se Crypto entrepreneur to go to space on New Shepard
A controversial Chinese cryptocurrency entrepreneur revealed he submitted the high bid for a seat on Blue Origin’s first crewed suborbital launch earlier this year and, after missing that flight, is buying a dedicated New Shepard flight in 2022.
Long March 7A launches classified Shiyan-12 satellites
China launched a new-generation Long March 7A rocket Thursday, successfully sending a pair of Shiyan-12 test satellites into geosynchronous transfer orbit.
JWST launch marks only the start of a risky deployment process
While the impending launch of the James Webb Space Telescope has astronomers both excited and nervous, the liftoff marks only the beginning of the riskiest part of the mission.

Kepler plots relay network to serve thousands of satellite terminals
Kepler Communications plans to use a Spire Global nanosatellite launching late next year to test a terminal it hopes to someday deploy by the thousands to create a mesh network of data-relay satellites.
Testing radar to peer into Jupiter's moons
A 1:18 scale model of Juice, ESA's spacecraft to explore the Jupiter system, is being employed to test its radar antenna.
The working version of the RIME instrument (Radar for Icy Moons Exploration), incorporating a 16-m long version of the straight 'dipole' boom seen here under the model spacecraft, will probe up to 9 km deep under the surfaces of the gas giant's main "Galilean' moons.
The testing took place in ESA's Hertz (Hybrid European RF and Antenna Test Zone) chamber based at ESA's ESTEC technical heart in the Netherlands.
Metal walls screen outside radio signals, while spiky foam interior cladding absorbs radio signals internally to create conditions simulating the infinite void of space.
This chamber's hybrid nature makes it unique: Hertz can assess radio signals from antennas either on a local 'near-field' basis or as if the signal has crossed thousands of kilometers of space, allowing it to serve all kinds of satellites and antenna systems.
A scaled model of the #JUICE Radar antenna is under characterization test @TestCentre.
