Behold, the hundreds of free e-books about space history contained on this webpage.

From old favorites like The Difficult Road to Mars: A Brief History of Mars Exploration in the Soviet Union and Wind Tunnels of NASA to experimental work like Aerospace Food Technology and Life in the Universe: Proceedings of a conference held at NASA Ames Research Center Moffet Field, California, June 19-20, 1979, this is one of the best collections of space arcana you’re likely to find.

Who could resist Exploring Space With a Camera? Or Rockets and People, the autobiography of rocket designer Boris Chertok and a key history of the Soviet space program?

These books were placed online over the last decade, so some of the formatting leaves something to be desired. Many of the works have been broken up into tiny pieces, forcing one to click through page after page. But this is a singular information repository, a storehouse for our fascination with flight.

What these works also show is how central the space program made and found itself during the 20th century. NASA could convene PIllsbury and the chefs on nuclear submarines to talk about food. Computing and solar energy were both pushed along by NASA’s interest. The Space Race was a proxy skirmish in the Cold War. And, of course, all sorts of ideas from the era leaked into the way NASA thought about things: freedom and America and gender and aesthetics and the future.

Oh, and don’t miss a personal favorite, We Freeze to Please: A History of NASA’s Icing Research Tunnel and the Quest for Safety. A page turner.

Looking in the mirror from 898,410,414 miles away…
NASA has just released a raw edition of Friday’s photo of Earth and the moon, as seen from the Cassini spacecraft currently orbiting Saturn.
From out there, we look like stars. 
Just a tip, NASA: We’re gonna have to give it a better name than “N00213959.jpg”. Maybe “Pale Blue Sparkle”?
(hi-res at NASA website, a more processed version is sure to come… stay tuned)

Earth: Our Green Home

Launched on October 28, 2011, satellite Suomi NPP was flung into a sun-synchronous orbit around earth by a Delta II rocket and has since gathered large amounts of highly detailed data about the amount of vegetation on Earth’s surface. NPP is a mission partnered by both NASA and the National Oceanic and Atmospheric Administration (NOAA) and has been gathering data on the amount of vegetation on Earth through images in visible and near-infrared light. The satellite was able to incorporate the data into the Normalized Difference Vegetational Index (NDVI) which is used to measure the photosynthetic potential of vegetation across the world, as well as plant growth, and biomass production. Some quarter of the Earth is covered in vegetation, while the rest is blue ocean.

Consider that you can see less than 1% of the electromagnetic spectrum and hear less than 1% of the acoustic spectrum. As you read this, you are traveling at 220 km/sec across the galaxy. 90% of the cells in your body carry their own microbial DNA and are not ‘you’. The atoms in your body are 99.9999999999999999% empty space and none of them are the ones you were born with, but they all originated in the belly of a star. Human beings have 46 chromosomes, 2 less than the common potato.

The existence of the rainbow depends on the conical photoreceptors in your eyes; to animals without cones, the rainbow does not exist. So you don’t just look at a rainbow, you create it. This is pretty amazing, especially considering that all the beautiful colors you see represent less than 1% of the electromagnetic spectrum.

You guys like Saturn, right? Here’s a whole gallery of Saturn GIFs, from rings to moons, captured by the Cassini spacecraft. They’re part modern art and part science.

Next to the Voyager twins, I think Cassini might be the best satellite NASA ever launched. Certainly takes the best pictures. Tumblr’s own staceythinx  has an iPad app called Cassini HD that features even more photos, plus color, plus science.

It’s Time to Get Serious About Going to Mars, NASA Says
If NASA is to land humans on Mars by the 2030s, as President Barack Obama has directed, there’s not much time to settle on a plan and develop the technologies required, agency officials said Monday (May 6).In the 1960s, America seized an opportunity to go to the moon, and succeeded. A second opportunity for a leap forward in space is upon us now, said NASA chief Charles Bolden at the Humans 2 Mars Summit here at George Washington University.“Interest in sending humans to Mars I think has never been higher,” Bolden said. “We now stand on the precipice of a second opportunity to press forward to what I think is man’s destiny — to step onto another planet.” [Buzz Aldrin’s Visions for Mars Missions & More (Video)]
Yet the road to Mars is long and challenging, and the difficulties are scientific, technological, political and economic, experts said.Of Launches and Landings Sending astronauts to the Red Planet will likely require at least three missions: one to launch the crew and the vehicle that will take them to Mars, one to launch the habitat humans will live on at the planet’s surface, and one to launch the vehicle that will lift off from Mars to take the crew home, said Doug Cooke, a former NASA associate administrator for the Exploration Systems Mission Directorate who now heads a space consulting firm.
Overall, about 200 to 400 metric tons of equipment will have to be launched from Earth’s surface for the project — a mass roughly equivalent to that of the International Space Station. And about 40 metric tons of that mass will have to be delivered to the surface of Mars at one time. So far, NASA has been able to land only 1 metric ton at a time — a feat recently accomplished in nail-biting fashion when the agency landed the Curiosity rover last summer.
While this phase, called Mars entry, descent and landing, will be one of the most challenging elements of the mission, at least as difficult is the return, when the astronauts will have to lift off from the surface of Mars and travel home. [Missions to Mars: Robotic Invasion of Red Planet (Infographic)]
“To me this is one of the biggest challenges,” said Mike Raftery, director of space station utilization and exploration at Boeing, the primary contractor for NASA’s heavy-lift rocket being developed to go to Mars. “We have to essentially land a launch pad on the surface that’s then ready to launch the crew back to Earth.”

Living Off The Land In addition to the launch system, Mars crews will have to bring their own life-support systems, medicine, food, communications systems and navigation equipment. Yet the space travelers won’t be able to pack everything they’ll need. Instead, they will have to take advantage of some of the resources on Mars, such as water and oxygen for breathing, drinking and other needs. However, the technologies needed to extract and use such resources don’t yet exist.
“We’re going to have to rely on being able to live off the land,” said James Reuther of NASA’s Office of the Chief Technologist. “Those will require significant technology investments in order to actually bring that about.”
Engineers must also develop a means of shielding astronauts from the dangerous radiation in space, both during the journey to the Red Planet and on the Martian surface, which lacks a strong enough atmosphere to protect from these damaging particles.
And to adequately plan for a human landing, additional precursor missions may also be necessary.
“It’s very likely that we’ll send some kind of lander or rover to the site we want to send people to first, to drill a couple meters down to tell us if we have fresh water,” said John Grunsfeld, associate administrator for NASA’s science mission directorate. Such a spacecraft could also serve as a beacon to guide the crewed lander down to the chosen spot on Mars.
Despite the complexity of all these challenges, NASA has a limited amount of time to plan its mission if it wants humans to arrive in the 2030s.
Ticking Clock By 2020, engineers must choose an architecture for the mission, including what type of propulsion to use to get to Mars, and how many launches are required, said Sam Scimemi, NASA’s International Space Station director. It must also establish partnerships with any other nations it hopes to team with for the journey. By 2025, the design for all the major vehicles and technologies must be completed and frozen.
“That’s pencils down,” Scimemi said. “We don’t have a lot of time. If we’re going to get there we have to have a realistic approach from a budget, political and cultural standpoint.”
Still, many NASA and industry experts expressed confidence it can be done.
“In the coming days we have the opportunity to write history, to determine the future of humankind,” said Artemis Westenberg, president of Explore Mars Inc., the nonprofit space advocacy group that organized the conference. “We of Explore Mars give you this platform of this three-day summit. Now all you have to do is tell each other and the world the how” of getting to Mars.
