The Philae lander (PHILAE) transmitted a lot of data collected by its instruments for about a minute and a half, through the mother spacecraft Rosetta

European Space Agency scientists have received a signal of life from the Philae lander, seven months since contact with it was lost, shortly after it completed the first ever landing on a comet. "Pillai" was equipped with batteries that were supposed to last 60 hours, and was then designed to generate energy from its solar panels. However, due to a malfunction in the landing, it eventually settled in the shadow of a large rock, and did not receive enough light to generate electricity after its batteries were exhausted.
European agency scientists expressed hope that the lander will return and be exposed to light as Comet Churyumov Gersimenko approaches the Sun. Today, as mentioned, contact was made with the lander for about a minute and a half, during which the lander sent a lot of data collected by its instruments, through the mother spacecraft "Rosetta", which continues to circle the comet. The scientists hope that the connection with the lander will stabilize as the comet gets closer to the sun in the coming weeks. "We hope to restart all the instruments in the coming days and apply again to collect data on the comet from the ground, alongside those collected from above by the mother spacecraft," says ESA scientist Mark McCochrane to the BBC:
"The interesting thing is that the comet is now much more active, due to its proximity to the Sun, and we hope that this activity will provide us with new information about comets."
In the coming days, the scientists and engineers will try to check if the lander's instruments are working properly, and were not damaged during the prolonged freezing period. Among other things, they hope to complete the main task that "Pilay" did not complete upon landing - to drill into the comet's soil, and analyze the composition of the samples.

Already GPS satellites must use both special and general relativity. Beyond that, an accurate calculation of the position of the star over a long distance and over a long period of time requires complex calculations.
In order to land such a lander on a planet, only Newton's laws are required, or is it necessary to enter a more complex field in science?
