On the possibility of space travel.
By David W
In 20 to 40 years, space enthusiasts will walk the stars when NASA decreases the costs from $10,000 per pound to 100s of dollars to 10s of dollars per pound of material into space.
It currently takes 143,000 gallons of fuel to go to space. But space travel is getting cheaper, because more people are advancing space technology and efficiency, and this causes a decrease in cost per flight, as efficiency trumps cost.
Reporter: “would you like to go to space?” Joy Weir, respondee, “Yes.” reporter: “what are the downsides of space travel?” Joy Weir: “very expensive, possibly more than I have to spend.” reporter: “what if I told you that cost will decline over the years. What if I told you the cost will only be $10 per pound into space?” Joy Weir: “I think it is great that the cost is less later on” reporter: “are there any other concerns you still have about this opportunity?” Joy Weir: “I am worried about trash in space. If it is cheap to travel to space, people will pollute space. But I would like to see a firsthand view of earth from space.” reporter: “thank you for your time, Joy Weir.”
The speeds of reentry are immense (mach 25, or 17,500 miles per hour.), and this causes a lot to be added to the cost of going to space because heat shields are very heavy. This is a very important piece of tech, and can be improved greatly, with time. This is a major part of overall cost reduction.
The speeds of getting into orbit is also very high, 7824 meters per second. This speed won’t change, but it can be reached very efficiently, unlike the way we do it now. This is also the biggest contributor to cost because fuel is expensive, and manufacturing containers is also heavy on cost. It takes 143,000 gallons of fuel.
But space tourism will cause a lot of space junk. This could cause the tourism to die out, because if a rocket hits a piece of space junk, it could rupture, causing death of all on board persons. This is even more of a problem because each rocket causes more space junk.
Who’s Better Samsung or Apple?
Does Apple have more pros than Samsung and does Samsung have to many cones? Samsung has a history of phones breaking, but at the same time gives good quality gadgets with low price. Apple, on the other hand, is more popular and makes more luxurious phones, but because it’s Apple and more luxurious, the price is high. What I mean by luxurious is stainless steel edges, glass back, and a beautiful box. Samsung pros: pro 1 less expensive, pro 2 cost less to repair screen, pro 3 Samsung buds and Gear watch are compatible with any device, pro 4 has a headphone jack. Samsung cones: con 1 very little amount of stores, con 2 images don’t look real when you take a photo, con 3 can’t message
Samsung people in a iPhone group, con 4 sim-tray is plastic and can break easily. Apple pros: pro 1 very beautiful phone, pro 2 a lot of stores, pro 3 the iphones have lots of different colors, pro 4 Apple ax6 is the fastest chip ever made. Apple cones: con 1 no headphone jack, con2 back glass is super easy to break this is what jerryrig everything said “the back glass is super easy to break and only one drop can cause it to break and to fix it it cost 349-599 dollars.” con 3 Apple phone is only compatible with apple watch and not gearwatch from Samsung or other watches, con 4 you cannot listen to music and charge, because there is no headphone jack. We heard about what Apple and Samsung offer, hopefully you found out what to buy from what company. Thank you for reading.
Scientists are researching Mars’ environment in hopes to find live able parts for Humans hopefully in the near future
By Jake Gordon
Nasa and other companies are studying on when or if humans will ever be able to live on mars. This means that we might be able to have people live at both planets so we can balance out different populations, and hopefully the environmental problems go down by a large portion.
Scientists are focusing on Mars out of all the planets because it is inside a zone called the “Goldilocks Zone” this is a zone that is within a certain distance of the sun so the temperatures are liveable. That is only partly what the scientists are looking for though. During 2013 a large spike of a gas called methane was detected by some satellites. Scientist began concentrating even more on Mars. The reason for this is because methane is a gas often made by organisms such as Martian Microbes which is what scientists are hoping, because that shows that life on Mars at least for the atmosphere might be liveable. The methane seems to spike randomly so it is hard to tell whether people can live there or not. One scientist named Dr.Giurunna said “The methane could be released episodically along faults that break through the Permafrost due to partial melting of ice.” Luckily this is only a theory and there could still be microbes living on Mars and if Microbes can surely we can sometime in the near or distant future, especially with all of the amazing scientists constantly studying the surface, minerals, pressure, and gasses in Mars’ environment. All hope for living on Mars is not lost and will most likely workout for humanity.
