A retired NASA satellite is expected to fall to Earth on Sunday after spending nearly 40 years in space, space officials said Friday.
The U.S. Defense Department has predicted that the 5,400-pound Earth Radiation Budget Satellite will reenter the atmosphere sometime within a 17-hour window of 6:40 p.m. EST on Sunday, NASA said in a statement.

Once in 50,000-year comet may be visible to the naked eye
Saturday, 07 January 2023 09:55
A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said.
The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year.
After traveling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.
It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon.
The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transient Facility, told AFP.

President Vladimir Putin on Wednesday presided over the launch of a warship armed with new hypersonic cruise missiles on a training mission to the Atlantic and Indian Oceans and the Mediterranean.
"I am sure that such powerful weapons will make it possible to reliably protect Russia from potential external threats and will help ensure the national interests of our country," Putin was quoted Raytheon Intelligence and Space awarded Missile Track Custody development contract

Raytheon Intelligence and Space has been awarded a prime contract to develop a prototype Missile Track Custody system for the U.S. Space Force. MTC is the service's first Medium Earth Orbit missile tracking system.
Under this contract, Raytheon Intelligence and Space will serve as the prime contractor, developing and delivering a space vehicle, hosting a state-of-the-art missile tracking m Australia buys Ukraine-tested US missile system
Friday, 06 January 2023 08:33
Australia said Thursday it has snapped up a US offer to obtain the same long-range, mobile rocket system Ukraine has deployed on the battlefield against invading Russian forces.
The government said the High Mobility Artillery Rocket System (HIMARS) would deter attacks on Australia but could also be transported by plane for deployment worldwide.

Friday, 06 January 2023 08:33
Russia has blamed the deaths of scores of its soldiers in a New Year missile strike on its troops using unsecured, traceable mobile phones on the battlefield.
But if Ukrainian forces did use geolocation of phones to target its strikes, it also reveals the Russian army's operational carelessness in the field, say analysts.

Friday, 06 January 2023 08:33
Black carbon aerosols are produced by the incomplete combustion of fossil fuels and biomass, and are characterized by strong light absorption. Black carbon deposition in snow/ice reduces the albedo of snow/ice surfaces, which may accelerate the melting of glaciers and snow cover, thus changing the hydrological process and water resources in the region.
