Recent studies have indicated you can either do human Mars missions in the 2030s with more money that NASA current receives, or wait until mid-century on NASA's current budget. Jeff Foust reports on a new study that finds, although with few details, that humans to Mars by the 2030s can fit within NASA's current budgets. Visit http://ift.tt/19Z0jDV to view the article. (4/6)
"Moon to Moon to Mons": Synergies for Moon and Mars Development (Source: Space Review)
The Moon, and the moons of Mars, have previously been proposed as key steps towards getting humans on Mars. Al Anzaldua and Dave Dunlop propose an approach that involves those bodies, as well as Martian volcanoes, as key steps in a sustainable long-term exploration strategy.

Yes, NASA is Reconsidering the Moon, and Here’s Why That’s Important (Source: Houston Chronicle)
William Gerstenmaier, the chief of human exploration for NASA, does not see the existing plan of a direct, 900-day mission to the red planet as achievable. Most significantly, Gerstenmaier believes large amounts of ice at the lunar poles may provide an important reservoir of oxygen and hydrogen fuel to propel rockets and spaceships across the 40 million miles of space to Mars. This may involve human activity on the moon’s surface.
Additionally, NASA officials have begun talking about an “Evolvable Mars Campaign,” which recognizes the technical and financial challenges of reaching Mars, and the likelihood that the United States would not support an all-out, Apollo-like plan. NASA has not laid out details of how it will actually get humans to Mars, and the lack of concrete plans has caused much consternation among the spaceflight community. Despite the lack of detail so far, it is clear that until relatively recently NASA wasn’t contemplating serious and prolonged activities on and near the moon.
Editor's Note: A driving question here is (or should be) whether we want a flag-planting Apollo-style trip to Mars, or a sustainable exploration/habitation program (which could include the Moon). Both are hugely expensive, but a sustainable program is more aligned with our long-term national interests. If we choose only to plant a flag on Mars, I believe it should be an international project, while a lunar program might involve the U.S. private sector working with NASA. (4/7)
Fly Me to the Moon! (Source: Huffington Post)
This is the song that NASA should be singing right now. Yes, I know the current push by NASA on social media is #JourneytoMars, but are we ready? Really ready? Nope, I don't think we're even close. Most agree that Mars is the ultimate destination. And so do I. Theorists laud its "in situ" capabilities, with NASA Ames Research Center claiming (circa 2007) that "... in-situ resource utilization will enable the affordable establishment of extraterrestrial exploration and operations by minimizing the materials carried from Earth."
All this is well and good. But how do we do it? How do we process these wonderful life-sustaining elements to make our reality begin to look like the solar-powered, potato-rich, inflatable habitat reality experienced by fictional Astronaut Mark Watney in Andy Weir's highly acclaimed novel The Martian? We need companies like Caterpillar, Inc., John Deere, Ditch Witch and The Culligan Man to lead the way. Partnerships relying on these stalwart corporations would truly be space commercialization at its finest. Click here. (4/6)

Aerojet Rocketdyne Wins NASA Contract for Deep-Space Propulsion (Source: Sacramento Business Journal)
Aerojet Rocketdyne has won a $18 million contract from NASA to develop a deep-space propulsion system. The company makes all kinds of in-space propulsion for satellites in orbit, but this contract from the Glenn Research Center will be for interplanetary propulsion. It opens a potential new line of business for Aerojet Rocketdyne, which is often a subcontractor for defense companies. In this case Aerojet is a direct contractor for NASA. (4/6)
NASA Hosts Student Rocket Fair, Helps Students Launch High-Power Rockets (Source: NASA)
More than 30 high school, college and university teams will launch student-built rockets during the 15th annual NASA Student Launch event April 10-11 in Huntsville, Alabama. Middle school and high school teams will launch their rockets to an altitude of one mile, deploy onboard science experiments and land safely using a system of recovery parachutes. University and college teams will participate in either the Mini-Mars Ascent Vehicle (Mini-MAV) or the Maxi-Mars Ascent Vehicle (Maxi-MAV) divisions.
Mini-MAV teams must use a robotic system to autonomously load a payload into their rocket, launch to half a mile and eject the payload during descent. Maxi-MAV teams, competing for a share of $50,000 in prize money, will attempt to meet more autonomy requirements before also launching to a half mile. (4/6)

It's opening day of baseball season, and Terry Virts has a nosebleed seat to beat them all: the observation cupola of the International Space Station. The astronaut, photographer and baseball fan is commemorating the start of the season by tweeting a series of pictures showing Major League Baseball's cities, all taken from space. But he only posts the photos — his followers will need to figure out which cities are shown. (4/6)
Spiderlike Robots Could Build Giant Space Structures (Source: Space.com)
Humanity could soon be building huge structures in space one piece at a time, the way spiders spin their webs here on Earth. A company called Tethers Unlimited is developing an in-space manufacturing system called "SpiderFab," which would use arachnidlike robots to put together large objects in orbit or beyond.
SpiderFab could help build big radio antennas, spacecraft booms and solar arrays in the next decade or so, said Rob Hoyt, CEO and chief scientist of Tethers Unlimited. But he has an even grander vision for the technology (and associated projects the company is working on) over the long haul. Click here. (4/6)

Space Pact on Modi's Paris Plate (Source: The Telegraph)
India and France are planning to ink a pact for joint interplanetary exploration when Narendra Modi visits Paris on Friday, marking New Delhi's second foray into a space hunt beyond the moon after the Mars Orbiter Mission. The agreement will be a key diplomatic outcome of the Prime Minister's France trip at a time space cooperation has become a foreign policy priority with him, two senior Indian officials independently told The Telegraph.
A French embassy spokesperson said he would not like to comment. Modi and French President Francois Hollande will also discuss defense and nuclear cooperation, the Indian officials confirmed, requesting anonymity. "Using space research and its benefits diplomatically - that's a priority for the Prime Minister," one of the officials said. (4/6)
Swap Could Land Sally Ride Statue in D.C. (Source: UT San Diego)
A statue of the late Sally Ride, the first American woman in space, could one day replace that of Rev. Junipero Serra inside the U. S. Capitol, under a proposal being considered by state lawmakers this week. Ride, a La Jolla resident who devoted much of her life to science education, died of pancreatic cancer in 2012 at the age of 61.
The proposal to swap out Serra’s statue isn’t without controversy. It comes the same year Serra is set to be canonized by Pope Francis, causing religious leaders to call out what they believe is poor timing by state Sen. Ricardo Lara, D-Bell Gardens, who proposed the exchange. Assembly Speaker Toni Atkins, D-San Diego, is a co-author of the resolution. (4/6)
More Evidence for Groundwater on Mars (Source: Space Daily)
Monica Pondrelli and colleagues investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability. On the plateau, ELDs consist of rare mounds, flat-lying deposits, and cross-bedded dune fields. Pondrelli and colleagues interpret the mounds as smaller spring deposits, the flat-lying deposits as playa, and the cross-bedded dune fields as aeolian. (4/7)
