Space exploration is an important achievement for human beings which has resulted in a greater understanding of the universe. What is something that humans have done so far when exploring space? A. traveled to another planet B. observed life forms on Mars C. constructed a building on the Moon D. landed probes on several planets

What do you think makes space exploration so exciting? Why is space exploration important? Explain your ideas.

The lure of human space travel is undeniable. We’ve allgrown up on endless types of entertainment set in thefuture that portray adventures on distant planets. Imagineyourself as an astronaut, a part of the first manned mission toMars. Beyond that, there are generations of people who havebeen working to make space and space travel look cool, eveninevitable. But high aspirations and romance aside, we needto face the harsh realities. Our notions about the inevitabilityand wonder of human space travel need to be checked, andany plans need to be reconsidered. Some of the best reasons tocurtail space exploration come down to economics, human cost,and technology.1Should robots lead the journey to outer space?This writer says yes.Let Robots Take tothe StarsArgument by Eiren CaffallANALYZE ARGUMENTAnnotate: In paragraph 1, markthe author’s central claim andmark the reasons the author willuse to support the claim.Interpret: What will the author’sargument be?

To get humans to Mars,it would take $1 trillion over a 25-year period. Obviously, nosingle government would want to take on that kind of funding.A Mars mission would require international cooperation at asignificant cost to each partner nation. A Mars mission mightfoster international cooperation, but it would consume fundsthat could be used for other things.Some people suggest that the only way to get to Mars wouldbe with the help of private companies. Because of this, thespace exploration industry is made up not only of governmentagencies but also private companies headed by dreamersand people interested in profits over practicality. But theseorganizations are often badly managed. They don’t work for thegovernment, so accountability could be a problem. Even well-run companies are unlikely to have enough money to launcha Mars mission on their own. There are some experts who saythat it wouldn’t be possible to launch a mission to Mars withoutfunding from commercials that would run during coverage ofthe project. That would turn a scientific mission into a realitytelevision show. Would you want to trust a scientific mission tothe people who run reality TV?Space Travel Could Harm OurPolluted WorldThe risks of space exploration could be grave for a planetalready plagued by pollution. There is an extra result of spacetravel: black carbon from rocket exhaust that’s deposited inthe outer atmosphere. The launch of a suborbital tourist craftis said to produce less carbon emissions than a standard flightfrom New York to London. However, once the rocket is abovethe atmosphere, the black carbon it releases can be prettydamaging. Try to imagine the black smoke from a diesel trucksitting above the sky. With no weather to wash it into theoceans, black carbon can stay put for up to ten years.Many space boosters are suggesting that being able toleave our planet once it’s exhausted of resources is a priority.They seem to be proposing that we have some sort of Planet B.Somehow they think that a colony on Mars or the moon couldtake the pressure off our world. Many of these people planningto profit from two things at once are also fans of the dubioustechnology of geoengineering.

Explore the books / internet, and prepare a list of at least 30 scientific breakthroughs (10 discoveries /inventions in each branch of Science i.e. Physics, Chemistry and Biology) in the history of mankind. Out ofthe listed concepts, research and gather data on any three concepts.

Advancements in space technology have opened up new opportunities for exploration. Three planets, ______ Mars, Venus, and Jupiter, are now considered top priorities due to their potential for life and unique atmospheric conditions. These celestial bodies continue to captivate scientists and astronomers alike with their vast potential for discovery.25 Mark For ReviewWhich choice completes the text with the most logical transition?A) additionallyB) regardlessC) equallyD) namely
