Supply and Demand for Space Travel

Growing up seeing the NASA Apollo missions, it was easy for me to believe that I would see rockets  flying all over the solar system. Despite the triumphs of the Shuttle, ISS, and Mars rovers, the next 40 years did not quite live up to expectations. But the last 10 did. For forty years, the costs barely budged but they have fallen one hundredfold since 2010! See this cool info-graphic on truly revolutionary changes in costs.

When costs fall that much, we move way down on the demand curve. Once costly ventures such as colonies on the Moon, manned missions to Mars, and mining asteroids start to become feasible. Is this a one time drop in costs or will they continue to fall as more is learned?  My ten year-old self is giddy again.

  2. A few months ago, I felt so depressed, I got frustrated with bad credits, but then I contacted HACK VANISH by phone: +1 (747) 293-8514 and email: HACK VANISH (@) GMAIL. COM. I found out about hack vanish services through positive reviews read on some credit blogs, in a blink of an eye this great hacker restored my credit score from 509 to 784 in all 3 major credit bureaus, they got removed evictions and foreclosures, my LexisNexis and Chex system was repaired respectively, a few days later I received an email confirming the approval of my mortgage loan, it was quite surprising because I never thought it was possible. Today, I can confidently say that 2021 was a banner year for my husband and I as we now own a new house and a new SUV courtesy of HACK VANISH, I would definitely recommend him to anyone in need of a genuine Hacker.

  3. I lost my job few months back and there was no way to get income for my family, things was so tough and I couldn't get anything for my children, not until a met a recommendation on a page writing how Mr Bernie Wilfred helped a lady in getting a huge amount of profit every 6 working days on trading with his management on the cryptocurrency Market, to be honest I never believe it but I took the risk to take a loan of $1000. and I contacted him unbelievable and I was so happy I earn $12,500 in 6 working days, the most joy is that I can now take care of my family I don't know how to appreciate your good work Mr. Bernie Doran God will continue to bless you for being a life saver I have no way to appreciate you than to tell people about your good services.

  4. Hi viewers online, I'm here to share my testimony about how I was helped to get my husband back. I was a cheat and my husband caught me several times. I tried fixing myself and each time I ended up cheating over and over again. I guess I didn't realize what he meant to me until he had left me alone. I began to find a way to get him back but nothing seemed to work out perfectly until I came across an article about Lord Zulu who helped a lot of people globally to get their relationships back. I made contact with him and he assured me that my husband will come back to me within 48 hours with his powerful magic for the materials needed for the work. Surprisingly, my husband came back home after 2 days saying that he still loves me and I swore never to cheat on him anymore. All thanks to Lord Zulu. You can have a chat with him on his WhatsApp number or you can contact him on +1(909) 781-4612.
