flag of Ukraine

Russia began a full-scale invasion of Ukraine on 24 February 2022, in an escalation of the Russo-Ukrainian War that began in 2014. The invasion is the largest conventional military attack on a sovereign state in Europe since World War II.

The invasion received widespread international condemnation. Many countries imposed new sanctions, triggering a financial crisis in Russia.

On 2 March, the UN General Assembly voted 141 to 5 to demand Russia stop the war and withdraw all of its military forces; 35 countries abstained, including Algeria, Bangladesh, China, India, Pakistan, and South Africa, while Belarus, Eritrea, North Korea, and Syria were Russia's sole supporters.

Text extracts from, 2022-03-08.

In 1996 it seemed like a good idea to name a software application for the calculation of satellite ephemeris, to name this "Sputnik" after the first ever satellite. The Russian word Sputnik means satellite or fellow traveller.

I have now removed this application from the web site. Some other items of software have been moved to a different section of this web site.
