SpaceX launches second U.S. reconnaissance satellite on Falcon 9 rocket
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
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.

A study outlining priorities in planetary science for the next decade backs continued efforts to return samples from Mars while recommending NASA pursue missions to the planet Uranus and an icy moon of Saturn.
India examining crashed space debris suspected to be parts of China’s Long March rocket
India’s space agency is examining a large metal ring and a cylinder-like object that fell into rural western India April 2, with a preliminary investigation suggesting they could be parts of a Chinese space rocket’s upper stage that reentered the atmosphere that day.

Protecting GPS satellites and signals is essential to U.S. national and economic security. While some have opined that the solution is more and better GPS, the most effective and least expensive solution is to make GPS a much less attractive target.
