Russia’s attacks on Ukraine continue to take lives and destroy infrastructure as the country invades. This infrastructure damage has disrupted internet access in Ukraine, leading a government official to publicly request Starlink satellite internet access for the country from SpaceX CEO Elon Musk. Musk obliged, activating Starlink service in Ukraine and sending additional hardware. But with continued attacks on infrastructure, how will Ukraine stay connected?

Fedorov brings up an important point: Even though Starlink operates without the need for traditional internet infrastructure, the Earth-bound hardware still needs power. And, as Russian attacks bombard the country, Ukraine’s internet access will continue to be threatened.

Fedorov’s statement publicly reached out for help acquiring generators to keep Starlink online for Ukrainians. But Musk responded with an alternative suggestion.

“Solar panels + battery pack better than generator, as no heat signature or smoke & doesn’t run out of fuel,” Musk wrote in response on Twitter.

Elon Musk has some ideas.

SpaceX Starlink satellites twice approached the Chinese Space Station (CSS) in orbit, prompting China to warn of “close contacts” with Elon Musk’s space program.

Both the July 1 and October 21 incidents prompted the Chinese spacecraft to perform collision avoidance maneuvers. The Chinese team told the UN secretary-general in a diplomatic statement they provided earlier this month that on both occasions there were crew members on board, “which might represent a hazard to the lives or health of astronauts.”

Since its launch on April 29, the CSS “Tiangong” has maintained a nearly circular orbit at a height of around 390 kilometers with an orbital inclination of about 41.5 degrees.

HELSINKI — China’s Shijian-21 space debris mitigation satellite has docked with a defunct Chinese satellite to drastically alter its geostationary orbit, demonstrating capabilities only previously exhibited by the United States.

Data and tracking from space monitoring firms show that Shijian-21 has been conducting sophisticated rendezvous and proximity operations (RPO) with other objects in and around the geostationary orbit belt since its launch in October last year.

This activity culminated in Shijian-21 docking with the defunct Beidou-2 G2 navigation satellite and towing it above the crowded belt of geostationary orbit some 36,000 kilometers above the equator.

Starlink promises high speed and low latency internet access.

On Saturday, CEO Elon Musk posted on his Twitter page that Starlink service is active in Ukraine, with more terminals en route. Previously, Mykhailo Fedorov, vice prime minister of Ukraine, had tweeted to Musk on Saturday, February 26, calling for the tech billionaire to provide some assistance to Ukraine amidst the Russian attack on the country.

Starlink is designed to help people in areas without access to reliable, ground-based internet get online — so long as they have a view of the sky. Starlink promises high-speed and low latency service without relying on expensive ground-based fiber optic cables or local infrastructure. Just point a dish at the sky, and the supplied hardware will connect to the internet using the satellites orbiting above.

Once it’s in space, it’ll be known as GOES-18.

“A big part of the GOES-R [series] mission is actually doing solar observations,” said Pam Sullivan, NOAA’s GOES-R program director.

Before GOES-T can begin its weather-watching mission, it does have to reach space. To do that, it will need good weather.

Current forecasts predict a 60% chance of good weather at launch time on Tuesday, with conditions improving to 70% on Wednesday if NASA and NOAA have to delay for a day, said launch weather officer Jessica Williams of the 45th Weather Squadron at Space Launch Delta in the briefing.

Vice Prime Minister Fedorov reached out to Elon Musk for Starlink internet service in a last-ditch effort to restore internet access. As Russian forces approach Kyiv, Ukraine has been suffering internet problems.

Mykhailo Fedorov, Ukraine’s Vice Prime Minister and Minister of Digital Transformation contacted SpaceX CEO Elon Musk about the company’s Starlink satellite broadband service.

“While you are attempting to conquer Mars, Russia is attempting to invade Ukraine!” Fedorov said on Twitter. Russian missiles hit Ukrainian civilians as your rockets successfully land in orbit! We request that you send Starlink stations to Ukraine and direct all rational Russians to take a position.”

At the Vandenberg Space Force Base in California, SpaceX launched its second shipment of internet-bearing satellites on Friday. The satellites will deliver internet access to users all across the world.
