The spousal unit just sent me my boarding pass. A cute way to travel with NASA on Mars 2020, but I’ll have to bring my own life support.
Happy Anniversary to Apollo, NASA, America, and the World.
Apollo 11 launched on July 16, human beings walked on the Moon on the 20th, and the astronauts splashed down safely back on Earth on July 24. That’s over a week of anniversaries.
Space Center Houston‘s becoming a bit of a theme park (which means some things cost money and the web-site has annoying pop-ups asking you to subscribe – sigh) so if you’re in the area, check out events here. There are also some neat photos, info, and other stuff on their site.
NASA has reopened Apollo mission control at the Johnson Space Center after a restoration that makes it look like it did in 1969. There’s functioning electronics, familiar furniture and other attentions to detail. The New York Times noted that there are even period-appropriate soft drink cans and cigarettes. engadget.com
So, pull on a short-sleeved, white shirt and narrow, black tie; slide a bunch of pens into your pocket protector; and relive the drama of Apollo team members left behind on Earth.
You can find hours of Apollo 11 video on You Tube – join the mission yourself. I still get goosebumps and hold my breath as Armstrong pilots the lander. We copy you down Eagle.
Hopefully atmosphere observations in the future — of thick steam atmospheres — can support or refute the new findings. Goldschmidt Conference
Many of these detected exoplanets are larger than Earth, but it sounds like a lot of that extra mass is water – up to 50% of the planet’s weight, while water on Earth is only 0.02%. Our watery blue world is a desert in comparison.
It makes me wonder… if our Sun had more heavy elements, would Earth be larger? Would it have captured more of the solar system’s water? Would you and I be fish?
We have earlier generations of stars to thank for any watery world including our own. Hydrogen is, of course, everywhere – the most abundant element starting from the Big Bang. But heavier elements owe their existance to fusion within stars and subsequent nova and supernova explosions. That includes oxygen. So water seems to be common in the galaxy.
Commemorate the Earth’s largest recorded asteroid impact today, International Asteroid Day.
In 1908, a powerful asteroid struck the Podkamennaya Tunguska River in a remote Siberian forest of Russia. The event leveled trees and destroyed forests across 770 square miles, which is equal to the size of three-quarters of the US state of Rhode Island. The impact threw people to the ground in a town 40 miles away.
About to leave for Mars.
No, it cannot fly through space.
It hitchhikes for the ride.
Once its rover host
And backs off quite a ways,
Will relay orders from the Earth,
To test it makes the grade.
Can solar cells keep it charged,
And keep it warm at night?
Can it rise three meters high
On a ninety second flight?
Then we’ll have a helicopter
On another world.
As any that I’ve heard.
It may seem like a small step, but Mars’ atmosphere is like flying 100,000 ft above Earth’s surface, about three times the height of commercial airplanes. Many outlets cover this element of the Mars 2020 mission, including Reuters
Cassini’s last transmission arrived on Earth at 1146 GMT on September 15 as it plunged to a fiery end in Saturn’s atmosphere. The spacecraft had run out of fuel, but only after orbiting the ringed planet for an incredible 13 years. NASA sent it to burn up in Saturn’s atmosphere rather than risk contaminating any of the moons – which may harbor life.
We know more about Saturn than ever before – its storms, hexagonal jet streams, rings, and a seemingly endless supply of moons. We also know that an American agency can cooperate with the European Space Agency, the Italian Space Agency, and astronomers around the world for two decades on a single mission (more if the design phase is included.)
Cassini’s mission lasted over twice as long as expected. The Huygen probe that piggybacked along made the first landing ever accomplished in the outer Solar System and the first landing on a moon other than our own.
Along the way, Cassini confirmed Einstein’s general theory of relativity, measured the length of Saturn’s day, studied its fantastic rings, and discovered the amazing variety of its moons – including water geysers from warm water oceans and lakes of liquid methane. It showed scientist and citizen alike that the Saturn system is beautiful – a beautiful pinpoint in a beautiful universe.
If you think the money could have been better spent – tell me, do you believe humanity’s problems come from a lack of money? More likely, they arise from a lack of heart – or maybe from a lack of soul. Cassini gives us wonder, joy, and beauty. It feeds our souls. If you don’t feel that, if you don’t look up in wonder, I’m sorry for you.
One of the greatest legacies of the mission is not just the scientific discoveries it makes, and what you learn about, but the fact that you make discoveries so compelling, you have to go back. space.com
I couldn’t resist sending a cult to colonise Saturn’s moon, Titan.
We’ve all heard about the technology spinoffs from NASA to our everyday lives. Things like memory foam, freeze-dried food, firefighting equipment, emergency “space blankets”, DustBusters, cochlear implants, various computer and medical technologies, turning trash into oil, and putting better bubbles in our beer. (Oddly enough – not some things you’ve often heard mentioned – not Tang, Velcro, or Teflon.)
In this age of budget cuts, NASA wants you to know these spinoffs contribute to America’s economy by generating billions of dollars in revenue and creating thousands of jobs.
Truthfully, this sounds more like hype than research. The designers will only spend three days playing colonists. If they really want a feel for living in cramped quarters with little privacy or comfort, I’d recommend at least a month. But maybe contemplating a few conveniences for future explorers will help today’s apartment dwellers.
Less trendy but more important spinoffs are coming too – exploring farming on Mars may help us get more nutritional bang for our energy buck in drought-stricken regions on Earth. In the meantime,
…if IKEA can design a clothing storage system that works well inside a Martian habitat, it can certainly design a clothing system that works well inside your horrible apartment in Brooklyn.
Watch for their new collection in 2019.
Until humans step foot on the Red Planet, science fiction is your only route to Mars. Try my on Mars series – the first colonist take a one-way trip in the near-future. Start with Glory on Mars – Emma wants to explore and make a home on Mars with the first dozen colonists, but something is terribly wrong on the Red Planet.
