Age of Discovery: Missed Our Chance?

In summary, the conversation discusses the current state and future of space exploration, including the funding and priorities of different countries and organizations. The U.S. has plans for a lunar base and ongoing space missions, while other nations such as Europe and Japan are also increasing their involvement. The success of recent missions, such as the Mars exploration and the GRAIL mission, is highlighted, along with the rejected OSIRIS mission. The conversation also touches on the high cost of war and defense budgets, and how that money could have been used for scientific advancement. Finally, the conversation mentions an old article satirizing the amount of money spent on space missions.

It is all but gone, economies will not fund space probes any more, we have cocked up, missed our chance, instead of discovery we have wasted our money on other things, think i am wrong? we shall see, but i predict that any space mission will be a piddling effort in the future.

The U.S. has a long-term plan for a lunar base (announced by Mr. President himself, just a few months ago) and an active manless (robot) exploration program. I think Europe & Japan as well as some other nations will come to play an increasingly important role over time.

The latest Mars exploration with the two probes has been a phenomenal success and even surprised its designers. It would be a shame not to build on this experience.

Well - there are still missions planned and proposed.

AIAA Daily Launch said:
GRAIL mission will study lunar interior. New Scientist (12/14) reports, "A newly announced NASA mission" called the Gravity Recovery And Internal Laboratory (GRAIL) "will examine the Moon's interior with more than 100 times the sensitivity of previous missions." Set to be launched in 2011, GRAIL will consist of "two spacecraft flying in orbit around the Moon for several months" that will "make sensitive measurements of the Moon's gravity field." In particular, GRAIL will analyze the Moon's "far side, where [the gravity field] is relatively poorly known."

New Scientist notes, "Previous missions have revealed the gravity field is much lumpier than Earth's, which makes it harder for spacecraft to navigate there." Having accurate data in this regard "could be especially important starting in 2020, when NASA plans to return astronauts to the Moon." Although "Japan's Kaguya spacecraft has already deployed two daughter probes for the same purpose," the Kaguya's research "team has not promised to release the raw data from its gravity measurements." Also, "GRAIL's measurements will be more than 100 times as sensitive as Kaguya's."

Rejected OSIRIS mission would have returned asteroid soil samples. Arizona's Daily Star (12/14) reports that the Origins Spectral Interpretation, Resource Identification and Security mission (OSIRIS), a University of Arizona (UA)-backed proposal that was passed over in favor of the GRAIL mission, "would have launched a spacecraft to collect and return material from" near-Earth Asteroid RQ36, which is "rich in primitive carbon compounds." OSIRIS would have "investigated for nearly a year before returning five ounces of asteroid material to the Earth. The proposal was for a 2011 launch and 2017 return." While NASA's rejection of the project "was a bit of a shock," according to Michael Drake of the UA's Lunar and Planetary Laboratory, and the principal investigator for OSIRIS, "the lab will continue to seek funding for the asteroid-sample-return mission, modifying the proposal based on feedback from NASA officials." The Daily Star notes that "the ongoing Discovery program aims to launch a mission every 12 to 24 months."

NASA said:
NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.

Launch of the GLAST satellite is currently scheduled for no earlier than January 31, 2008 from Cape Canaveral Air Station, located on the eastern coast of Florida.

NASA's Gamma-ray Large Area Space Telescope (GLAST) is a powerful space observatory that will:
* Explore the Universe's ultimate frontier, where nature harnesses forces and energies far beyond anything possible on Earth.
* probe some of science's deepest questions, such as what our Universe is made of, and search for new laws of physics.
* explain how black holes accelerate jets of material to nearly light speed.
* help crack the mystery of stupendously powerful explosions known as gamma-ray bursts.
* answer long-standing questions across a broad range of topics, including solar flares, pulsars, and the origin of cosmic rays.

Of course, one is correct that the priorities seem to be elsewhere.

Yup. Notice how telecommunication and the like have improved over the past 20-30 years!

Electronics! Stuff and more stuff!

As for other priorities, I was thinking mostly about the various wars going on the $billions spent on those - ~ $200 billion/yr on the wars in Iraq and Afghanistan, not to mention the several $100 billions on the US defense budget.

And we could have discovered so much more with this money, but alas it has gone, the pot is nearly empty, de evolution will be the norm.

NASA Announces Plan To Launch $700 Million Into Space
May 3, 2006 | Issue 42•18

CAPE CANAVERAL, FL—Officials at the Kennedy Space Center announced Tuesday that they have set Aug. 6 as the date for launching $700 million from the Denarius IV spacecraft , the largest and most expensive mission to date in NASA's unmanned monetary-ejection program.

"This is an exciting opportunity to study the effect of a hard-vacuum, zero-gravity environment on $50 and $100 bills," said NASA Administrator Michael Griffin, who noted that prior Project Denarius missions only studied space's effect on fives and singles. "Whether the money is immediately incinerated because of hard radiation, or freezes in the near-absolute-zero temperature and shatters into infinitesimal pieces, or drifts aimlessly through the cosmos before being sucked through a black hole into another dimension, it will provide crucial information for our next series of launches, which will consist of even greater sums of money, in larger denominations."

Honestly Woolie, I think that we will wake up and things will be different when China gets their space program in high gear. We need to have another space race like in the '60's. We are not a forward thinking/planning society. We are completely reactionary. That is why we need someone like China to give us a swift kick in the butt to get us going again.

I think the west would loose any race with China, China constantly finishes mammoth tasks ahead of schedule an on budget, while we in the west throw money at projects , they throw in man hours.

I don't think that the future is as bleak as you make it out to be.

SpaceX is scheduled to launch their third Falcon I rocket in the first quarter of 2008, along with a Malaysian satellite on a separate flight in the first quarter. There are also scheduling flights of their larger rocket, the Falcon 9:

http://www.spacex.com/launch_manifest.php

Their whole business plan revolves around being able to launch everything at a quarter of the price of current launch systems.

In fact, Bigelow Aerospace is planning on launching a full scale inflatable space station in 2010, that you can actually buy timeslots on! They have already successfully launched two mock-up space stations that performed very well:

http://www.bigelowaerospace.com/genesis_II/ [Broken]

Not to mention the efforts by The Spaceship Company, which is a union between Virgin and Scaled Composites, where you can get a ticket on a suborbital flight.


Certainly, there is a lull in government space programs, especially since the Apollo and Voyager missions, but the private sector is looking to put space travel into a new arena
that was not foreseen and thought of as impossible to do only a few decades before.

It's not going to look the same, from here on out.

But this is just what, launching satellites, shutteling stuff to the space station and taking pictures? Maybe novel playtime for the rich?

I don't see private companies investing in deep space exploration for scientific purposes.

Yeah, I mean researching our solar system is great and all, but look at all the money that could be going towards things like cancer, aids, climate change and global warming research.

If i hear another word about GW, i will start feeding the cows baked beans.

Well, no, right now it's too expensive to do such things. But launching anything at 1/4 of the price that it currently takes is a great step towards space technology by any rubric.

The biggest thing still keeping space technology from being more affordable is the launch cost related to chemical rocket engines. That, and the transit time. Even the most advanced rocket technology for deep space is ion/plasma propulsion if I remember correctly, and such forms of propulsion have minuscule accelerations associated with them.

If enough people get over the fear of using nuclear technology in space, things will start looking even more different. There is simply no substitute for high-power, short trips on nuclear power. Instead of waiting years for the planets to align and then more years in transit time, we'd be able to send probes/people/material anywhere in much less than a year. This means that the costs would go down, the designs could be heavier and contain a larger variety of robust equipment, and we potentially would solve the microgravity bone loss problem by providing constant 1G acceleration.

Go and feed the cows baked beans wolram, the best thing I can hope for out of all this global warming hysteria is a warming to the idea of nuclear power as the main alternative. http://www.hyperionpowergeneration.com/ is one example.

Let's not forget the technologies (including electronics, communications, and materials) that were developed in the pursuit of "researching our solar system"... and there's no reason to think that more technologies won't arise from its continued research.

...assuming a cow's GI flora makes methane from baked beans. I think they make plenty o'methane all on their own.

Private companies do invest in basic scientific research with only a remote possibility of economic benefit. After all, they invest in ISS experiments. If they don't invest in deep space exploration, I assume it is because they can't even think of a remote possibility.

I think that interplanetary travel will be limited to robots for some time to come. The economics are overwhelming. The difference between the cost of life support for a robot holding a one-way ticket compared to a human going round-trip is astronomical. If we insist on getting souvenirs, we can get more of them by sending a robot on round-trip than we could with a human.
 

1. What is the "Age of Discovery" and why is it significant?

The Age of Discovery refers to a period of time, spanning from the 15th to the 18th century, in which European explorers and navigators set out to discover new lands, trade routes, and resources. It is significant because it led to major advancements in navigation, cartography, and global trade, as well as the colonization and exploitation of many parts of the world.

2. What were some of the major discoveries made during the Age of Discovery?

Some of the major discoveries made during the Age of Discovery include the New World (North and South America), the Cape of Good Hope in Africa, the sea route to India, and the Pacific Ocean. These discoveries greatly expanded the known world and opened up new opportunities for trade and colonization.

3. Why is it said that we "missed our chance" during the Age of Discovery?

It is argued that during the Age of Discovery, European nations missed the opportunity to establish a more equitable and sustainable relationship with the newly discovered lands and indigenous peoples. Instead, they focused on exploiting resources and establishing colonies for their own economic gain, often at the expense of the local populations and environments.

4. How did the Age of Discovery impact the world we live in today?

The Age of Discovery had a lasting impact on the world we live in today. It led to the spread of European languages, religions, and cultures to various parts of the world, as well as the exchange of goods, ideas, and technologies. It also had a significant impact on global trade and the formation of colonial empires, which have shaped the political and economic structures of many countries.

5. What lessons can we learn from the Age of Discovery?

One of the main lessons we can learn from the Age of Discovery is the importance of acknowledging and respecting the diverse cultures and perspectives of the world. The exploitation and colonization of indigenous peoples during this time highlight the consequences of viewing others as inferior and solely for the benefit of one's own society. Additionally, the Age of Discovery serves as a reminder of the need for ethical and sustainable practices in exploration and global interactions.
