Tianhe, the core module of China's space station, has completed its verification of key technologies and achieved its expected goal.
Yang Hong, chief designer of the space station system of the China Manned Space Program at the China Academy of Space Technology, made the remarks at a press conference in Beijing on Sunday.
Yang said the core module has been in orbit for almost one y Planet releases slew of datasets for planetary variables

SpaceX on Sunday successfully launched a U.S. spy satellite for the National Reconnaissance Office on its Falcon 9 rocket.
The company announced liftoff in the launch from the Vandenberg Space Force Base in California at 9:14 a.m.
The Falcon 9 carried the NROL-85 satellite that is used to collect and deliver "space-based intelligence, surveillance and reconnaissance," the office 100 km, the current Longest Distance of Quantum Secure Direct Communication

Confidentiality of communication is essential in modern societies. Traditional way of secure communication is to use encryption, which is based on the computational difficulty of certain mathematical problems such as factorizing large integers. In such schemes, the two parties first distribute a key using an asymmetric cryptographic algorithm such as RSA, which is based on the difficulty of inte NASA moon rocket headed back to Vehicle Assembly Building after testing delays

The launch of NASA's new moon rocket has been pushed back by nearly a month after the Space Launch System failed to complete necessary prelaunch testing, officials said Monday.
With the rocked estimated to lift off sometime between June 6 and June 16, NASA officials said that launching during that window now would be challenging after issues during the SLS's wet dress rehearsal prevente Perseverance at the Delta
Tuesday, 19 April 2022 08:42
Last week's blog talked about the rapid traverse of Perseverance to the Delta. This weeks blog entry will talk about the Delta itself, and why it is something worth rapidly traversing towards!
The prospect of the delta for me is that every day will be full of excitement and could bring anything. Let me explain that a bit further. On a space mission like M2020 you get used an exciting timel Navy conducts historic test of new laser weapon system

The ground-based laser system homed in on the red drone flying by, shooting a high-energy beam invisible to the naked eye. Suddenly, a fiery orange glow flared on the drone, smoke poured from its engine and a parachute opened as the craft tumbled downward, disabled by the laser beam.
The February demonstration marked the first time the U.S. Navy used an all-electric, high-energy laser weap Schedule effects of SLS rollback still uncertain

NASA managers said a rollback of the Space Launch System from its launch pad after three truncated countdown tests will allow them to address issues both at the pad and with the vehicle, but that it was too early to predict what it would do to the schedule for the vehicle’s first launch.

NASA is having a tough time testing the SLS
Monday, 18 April 2022 19:15
NASA's Space Launch System (SLS) has been having some problems getting tested since it rolled out onto launch pad 39B last month. These tests, called wet dress rehearsals, are used to find any problems with loading the propellant and verify that all of the rocket's systems are able to handle it being exposed to cryogenics.
After this most recent attempt on April 14th, it is clear that the SLS isn't ready for flight yet. The problems that the teams have been encountering have led them to make some procedural changes and slight adjustments in operations and software triggers. There are also the leak problems that have shown up that have to be addressed.
