Lockheed Martin beat out Raytheon for the new network of ground-based radars.

This radar system will be sited on the Kwajelein Atoll to improve the ability to identify and track objects in space.

Construction of the new Space Fence system on Kwajalein Atoll in the Marshall Islands is slated to begin in the fall of 2014 to meet the program’s 2018 initial operational capability goal.

The system’s design incorporates a scalable, solid-state S-band radar with a higher wavelength frequency capable of detecting much smaller objects than the Air Force’s current system. This improves accuracy, quickens response time and expands surveillance coverage.

Space clutter

Utilizing this powerful, new ground-based radar, Space Fence will enhance the way the U.S. detects, tracks, measures and catalogs orbiting objects and space debris with improved accuracy, better timeliness and increased surveillance coverage.

There is much to do given the on-going and growing orbital debris problem: Debris from space collisions, tossed away rocket stages, dead or dying spacecraft.

Fast-moving “space junk” orbiting the Earth can be lethal to spacecraft and satellites in their path.

Lockheed Martin will deliver up to two advanced S-band phased array radars for the Space Fence program. The Space Fence radar system will greatly improve Space Situational Awareness of the existing Space Surveillance Network.

Critical services threatened

Critical services are being threatened by space clutter that circles Earth, said Dale Bennett, executive vice president of Lockheed Martin’s Mission Systems and Training business.

“Space Fence will locate and track these objects with more precision than ever before to help the Air Force transform space situational awareness from being reactive to predictive,” Bennett said in a press statement.

Just how fragile is NASA’s human spaceflight program? Is it lost in space?

Get ready for the June 4^th release of a new report from the National Research Council (NRC): Pathways to Exploration – Rationales and Approaches for a U.S. Program of Human Space Exploration.

Members of the authoring committee will present the report’s findings and recommendations and respond to questions at a public briefing beginning at 11 a.m. Eastern Daylight Time, Wednesday, June 4.

NOTE: A live webcast of the June 4 event will be available for viewing at this site:

http://sites.nationalacademies.org/DEPS/ASEB/DEPS_069080

According to the NRC, “a national consensus on the long-term future of human spaceflight beyond the U.S. commitment to the International Space Station remains elusive.”

The NRC report, authored by a blue ribbon group, will describe the rationales for human spaceflight beyond low Earth orbit and develops recommendations that could guide the U.S. human spaceflight program “in a sustainable manner.”

For your viewing pleasure, Asif Siddiqi, a historian of science and technology, describes the major decisions that shaped U.S. human spaceflight in the 20th century.  Go to:

As NASA’s Curiosity rover wheels about the Red Planet, the robot is on the lookout for habitable environments – sites that could have supported microbial life in the past.

But new research led by a Brown University researcher suggests that slopes of a giant Martian volcano — once covered in glacial ice — may have been home to one of the most recent habitable environments yet found on Mars.

Arsia Mons is the third tallest volcano on Mars and one of the largest mountains in the solar system. A new analysis of the landforms surrounding Arsia Mons shows that eruptions along the volcano’s northwest flank happened at the same time that a glacier covered the region around 210 million years ago.

The heat from those eruptions would have melted massive amounts of ice to form englacial lakes — bodies of water that form within glaciers like liquid bubbles in a half-frozen ice cube.

Lakes colonized by microbial life?

Kathleen Scanlon, a graduate student at Brown University, led the new research work regarding Arsia Mons, published in the scientific journal, Icarus.

Back-of-the-envelope calculations suggest that the lakes could have persisted for hundreds or even a few thousand years, according to a press statement from Brown University.

That may have been long enough for the lakes to be colonized by microbial life forms, if in fact such creatures ever inhabited Mars.

The fact that the Arsia Mons site is relatively young makes it an interesting target for possible future exploration.

For example, the NASA Mars 2020 mission is a future rover designed to investigate key questions about the habitability of Mars, and assess natural resources and hazards in preparation for future human expeditions to the Red Planet.

The science instruments aboard the rover will enable scientists to identify and select a collection of rock and soil samples that will be stored for potential return to Earth in the future.

Scientists are now reviewing projected exploration sites for the Mars 2020 mission.

Buzz Aldrin and I had a wonderful day in Denver on Saturday, May 24^th.

In promoting our book — Mission to Mars: My Vision for Space Exploration – we visited both the Barnes and Noble bookstore in Glendale, Colorado as well as the magnificent Wings Over the Rockies Air & Space Museum gala event in Denver that night.

At both events we were welcomed by large and receptive audiences.

As for walking on the Moon, 45 years ago this July, “it’s slow and it’s dusty…but it makes for beautiful boot prints,” Buzz told the Barnes and Noble crowd. But Buzz also had strong words regarding the overall health of the U.S. space program.

2013-14 State of the Future by Jerome C. Glenn, Theodore J. Gordon, and Elizabeth Florescu; The Millennium Project, Washington, D.C.; $39.95 US + shipping (soft cover); 2014.   

“It’s tough to make predictions, especially about the future,” said baseball great, Yogi Berra. However, you can get a big assist in foretelling what’s ahead by reading an important book produced by The Millennium Project, an international participatory think tank established in 1996.

“Humanity is slowly but surely becoming aware of itself as an integrated system of cultures, economies, technologies, natural and built environments, and governance systems,” the book notes.

The Millennium Project has gathered the insights from creative and knowledgeable people around the world to identify and update prospects for 15 Global Challenges to provide a framework for understanding what is important to know about global change.

In terms of making use of space and aerospace technologies, this volume underscores what humankind faces when pondering our collective future. The book, in a sense, is a solid primer on how the space program may contribute to solutions. In fact, one of the books contributors, Theodore Gordon, was manager for the third stage of the Saturn V rocket.

In one general observation, what is needed is a U.S.-China 10-year “Apollo-like” environmental security goal with a “NASA-like program” that other nations can join once established. Indeed, the book also notes that a global collective intelligence system is needed, one that can not only track science and technology advances – but also understand the potential consequences of new and possible future scientific and technological advancements.

The book reviews the trends of 30 variables used to create a global State of the Future Index and provides a score card on humanity’s performance in addressing the most important challenges.

Again, this is not a book specific to space. Nonetheless, if one tenant of the U.S. space program is to bring space down to Earth, this is a wise read. Once you have read this volume, you’ll realize we’re clearly behind in appreciating what’s ahead.

Note: Check out a video that spotlights the report’s release and observations, held at the Woodrow Wilson Center. A panel discussion involves Dennis Bushnell, Chief Scientist at the NASA Langley Research Center, Jerome Glenn, CEO, The Millennium Project, and Paul Werbos, Program Director, National Science Foundation.
