Inside NASA’s moon suit plan

By Tom Jones

November 1, 2019

The current International Space Station spacesuit, designed 40 years ago for extravehicular activities from space shuttle orbiters, would frustrate any moonwalker. Veteran spacewalker Tom Jones looks at how NASA will build a moon suit in time for the planned 2024 lunar return.

Artemis must learn from Apollo

By John M. Logsdon

October 1, 2019

The Apollo program proved to be unsustainable. If NASA and the Trump White House want to avoid the same fate for their Artemis lunar program, they should learn from Apollo’s history. Space historian John Logsdon shares some of the lessons he sees.

The necessity of returning to the moon

September 2, 2019

For 50 years, Americans have taken the moon for granted. Planetary scientist and former astronaut Tom Jones argues that returning there soon is an essential step toward other worlds, and continued leadership on this one.

Winning the moon race

By John M. Logsdon

July 1, 2019

The Apollo 11 moon landing still amazes, not just as a technological achievement but as a feat of political will by a democratic society. Space scholar John Logsdon has spent a good part of his career thinking about why and how this bold mission succeeded. Logsdon depicts how the U.S. made what is arguably humanity’s greatest achievement.

Gene therapy could one day make it possible to biologically enhance humans to live and work in deep space. Adam Hadhazy checks in on this nascent idea.

A safer spacesuit

By Amanda Miller

May 1, 2019

U.S. astronauts on the moon or Mars will need a spacesuit that won’t injure or exhaust them. One hurdle is that no one knows exactly what goes on in a physical sense when an astronaut inside one of today’s spacesuits moves his or her limbs. Amanda Miller visited with student researchers in Colorado who think they know how to find the sore spots in today’s suits, a breakthrough that could point the way to better designs, perhaps including one of their own.

A bridge to Mars

By Tom Jones

May 1, 2019

Beyond the moon, sending astronaut explorers to near Earth asteroids in the 2030s would open intriguing, resource-rich objects to in-depth inspection and exploitation, smoothing the daunting path to Mars. Former astronaut Tom Jones makes the case.

An easily overlooked, yet critical element of long-duration lunar or Martian missions will be dealing with all of the garbage we humans inevitably produce.

Space nuclear power — seriously

By Tom Jones

March 1, 2019

NASA is testing technologies to bring nuclear fission power to human spaceflight. Former astronaut Tom Jones explains why the move is long overdue.

Countdown to Commercial Crew

By Amanda Miller

January 31, 2019

Boeing and SpaceX are poised to make 2019 the breakthrough year in the nearly decadelong effort to get the U.S. back in the business of launching astronauts to the space station and bringing them home. Amanda Miller looks at the stakes and steps ahead for the Commercial Crew program.

Stepping stone

January 2, 2019

Assuring safety to the maximum extent possible for a human mission to Mars depends in large part on proving technologies and procedures through human exploration of the moon. Once those techniques and procedures are proven, there should be no need for a human precursor orbital mission to Mars. Mike Helton, a retired risk management expert who once worked on the Apollo missions, explains.

Returning to flight

By Tom Jones

January 2, 2019

In spaceflight, failures are inevitable. If a commercial launch vehicle fails while flying NASA astronauts, how would NASA and the service provider return their systems to flight and assure astronaut safety? Veteran astronaut Tom Jones examines how NASA might cope with catastrophe.

Safety requires the right culture

October 31, 2018

Russia’s botched launch last month of an astronaut and cosmonaut to the International Space Station was good news in that no one died, and in another sense too. NASA and Roscosmos received a non-fatal wake-up call about spaceflight safety. Those involved in this brush with tragedy should dig below the proximate technical causes of the failure of the Soyuz rocket to examine cultural factors. James Oberg, a Houston-based space expert, explains. 

The perilous road to Mars

By Adam Hadhazy

October 31, 2018

Mission planners are now fully coming to grips with the twin hazards posed to astronauts by long durations in weightlessness and exposure to cosmic radiation. Scientists and engineers are working on faster propulsion technologies to cut down on trip time, as well as a suite of countermeasures, aimed at bringing the red planet safely within human reach.

Once we went to the moon

By John M. Logsdon

September 27, 2018

The circumstances that led the U.S. to undertake the Apollo 11 lunar mission 50 years ago next July, and the five landings that followed, were unique, and they won’t be repeated. Even so, space historian John M. Logsdon sees reason to anticipate that U.S. astronauts will in the next decade return to the moon.

Quantum promises

By Amanda Miller

September 27, 2018

Precise navigation will be a necessity for safe human exploration of Mars and other celestial bodies in deep space. A pair of experiments about to get underway could change the way this navigation is done, and for the better.

Moon ship rising

NASA’s Orion spacecraft is intended to fly astronauts into lunar orbit on regular visits to a planned deep-space platform called the gateway. Veteran astronaut Tom Jones recently visited the Orion assembly line at Kennedy Space Center to assess the craft’s progress and path into translunar space.

Dreaming big

By Amanda Miller

July 1, 2018

If all goes as Sierra Nevada Corp. hopes, you’ll soon be hearing a lot more about Dream Chaser, the spacecraft with a history of ups and downs. Amanda Miller toured the new Colorado facility where the first spaceflight version of Dream Chaser will be built.

An astronaut remembers John Young

By Tom Jones

May 31, 2018

Astronaut John W. Young died at age 87 on Jan. 5. He was the ninth human to walk on the moon, flew six space missions, and served as an astronaut for over four decades. Veteran astronaut Tom Jones, who trained and flew (aircraft) with Young, remembers his personality and character.
