If all the solar incident on Mars were to be captured with 100% efficiency, then Mars would warm to Earth-like temperatures in about 10 years. However, the efficiency of the greenhouse effect is plausibly about 10%, thus the time it would take to warm Mars would be ~100 years. This assumes, of course, adequate production of super greenhouse gases over that entire time. The super greenhouse gases desired for use on Mars would be per fluorinated compounds (PFCs) as these are not toxic, do not destroy ozone, will resist degradation by ultraviolet life, and are composed of elements (C, S, and F) that are present on Mars. Fluorine has been detected on Mars by Curiosity.

The Warming Phase of a terraforming project on Mars results in a planet with a thick CO2 atmosphere. The thickness is determined by the total releasable CO2 present on Mars.

The temperatures would become well above freezing and liquid water is common. An Earth-like hydrological cycle is maintained. Photosynthetic organisms can be introduced as conditions warm and organic biomass is thus produced. A rich flora and fauna are present. A natural result of this is the biological consumption of the nitrate and perchlorate in the.

Ravioli-shaped moon.


In a stunning set of close-ups, Pan, a diminutive moon of Saturn, looks like a floating ravioli lost in space, or a wrinkled flying saucer.

NASA’s Cassini spacecraft took the photographs Tuesday, passing within 15,268 miles of the moon, which has a diameter of about 20 miles, roughly the size of New York City.

Carolyn C. Porco, a visiting scholar at the University of California, Berkeley, who leads Cassini’s imaging team, was asleep when Cassini’s shots were transmitted to Earth. She first saw an image on Twitter.

NASA scientists have proposed a bold plan that could give Mars its atmosphere back and make the Red Planet habitable for future generations of human colonists.

By launching a giant magnetic shield into space to protect Mars from solar winds, the space agency says we could restore the Red Planet’s atmosphere, and terraform the Martian environment so that liquid water flows on the surface once again.

Mars may seem like a cold, arid wasteland these days, but the Red Planet is thought to have once had a thick atmosphere that could have maintained deep oceans filled with liquid water, and a warmer, potentially habitable climate.

This summer, an ice chest-sized box will fly to the International Space Station, where it will create the coolest spot in the universe.

Inside that box, lasers, a vacuum chamber and an electromagnetic “knife” will be used to cancel out the energy of gas particles, slowing them until they’re almost motionless. This suite of instruments is called the Cold Atom Laboratory (CAL), and was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California. CAL is in the final stages of assembly at JPL, ahead of a ride to space this August on SpaceX CRS-12.

Its instruments are designed to freeze to a mere billionth of a degree above absolute zero. That’s more than 100 million times colder than the depths of space.

President-elect Donald Trump often says that Americans no longer dream and must do so again. Nowhere can dreams be more inspiring and profitable than in space. But today, expanding space enterprise is not foremost on the minds of Americans or military strategists. As a recent CNN special showed, defense thinkers feel embattled in space, focused on protecting our existing investments rather than developing new ones that seize strategic advantage.

The U.S. is studying a possible manned mission around the moon as early as next year, marking the first such trip since the Apollo era ended in the early 1970s.

Following requests from the White House, the National Aeronautics and Space Administration has formed a team to examine accelerating earlier plans to launch a crew by 2021, William Gerstenmaier, associate administrator of the agency’s Human Exploration and Operations Mission Directorate, said Friday. Preliminary results of the review should be ready in about a month.

“We have a good, crisp list of all the things we would physically have to change” on the launch vehicle under development, Gerstenmaier said on a conference call with reporters. “We asked the team to take a look at potentially what additional tests would be needed to add crew, what the additional risk would be.”
