Launch of Northrop Grumman’s 20th Cargo Mission to the Space Station (Official NASA Broadcast) - Cape Canaveral Space Force Station

It is the first time the Northrop Grumman Cargo Cygnus spacecraft has flown on a SpaceX Falcon 9 rocket.This Cygnus is named SS Patty Hilliard Robertson to commemorate the late NASA Astronaut Dr.Patty Hilliard Robertson,who perished in a plane crash in 2001.Among the experiments onboard Cygnus are a demonstration of robotic surgery in space,3D printing of small metal parts in space,and a test of heat shield materials.

About the Einstein Probe and Einstein's prediction of Gravitational waves

Einstein's General Theory of Relativity predicted the existence of Gravitational waves caused by massive events in the universe.These were not detected in Einstein's lifetime,however.The first indirect evidence of Gravitational waves was deduced in 1974 from the motion of a double neutron star system,leading to their maerger.The first direct observations of Gravitational waves took place on 14 September 2015 by the LIGO and Virgo collaboration.The signal was evidence of the inward spiral and merger of two black holes.A third possibility of detecting Gravitational waves would be the assyemetrical explosion of a supernova.So far,no such event has been detected,as supernovas are generally spherically symmetrical;only the mergers of black holes and neutron stars have been captured.

Einstein Probe launch

Einstein Probe explained - astrophysics

The Einstein Probe is a collaboration of the Chinese Academy of Sciences (CAS),ESA,and the Max Planck Institute for Extraterrestrial Physics (MPE),Germany.The EP has nextgen X-ray instruments of high sensitivity and a very wide field of view to detect X-ray blasts from sources such as neutron stars and black holes.

Justice and the Law:Ty Cobb says Trump poses ‘greatest threat to democracy that we’ve ever seen'

NASA Discusses Upcoming Artemis Crew Missions (Jan. 09, 2024) - starts at 5:17

New Timetable for Artemis Crewed Missions:Artemis II - September 2025;Artemis III Lunar landing:September 2026 Why:Analysis of Artemis I data brought certain potential flaws to NASA's attention.Specifically,1.A small amount of charring that they hadn't expected occurred on the Orion heat shield,and they need to work through that to be comfortable with crew safety.2.A circuit issue with the life support system needs to be worked through.3.An issue with the launch abort system was identified and needs to be resolved.4.SpaceX has had setbacks with its Starship spacecraft,which is to serve as the lunar lander for the Artemis III astronauts.They need more time to process the issues and will do an uncrewed test with Starship landing on the Moon and then returning to Earth.The first priority is astronaut safety.We're not going till we're ready,NASA Administrator Bill Nelson said.He doesn't think China will get astronauts to the Moon first.NASA and its industry partners are comfortable with the new schedule.

The first Vulcan rocket launch - 8 January 2024 - Cape Canaveral Space Force Station

The United Launch Alliance Vulcan Centaur rocket operated nominally on its inaugural flight.The Peregrine lunar lander experienced a serious propellant anomaly while in Earth orbit and is not expected to reach the Moon.Some of the experiments onboard Peregrine may be operable,however,and Astrobotic Technology will salvage what it can of the mission.It was the first of NASA's new Commercial Lunar Payload Services (CLPS) missions,a high risk effort to encourage commerical access to the Moon,paving the way for crewed lunar landings by the Artemis missions.
