space fever in astronauts could jeopardize landing on mars


astronauts in space suffer from persistently elevated body temperature, which can reach up to 104 degrees fahrenheit (40 degrees celsius) when they exercise, a new study has found.






astronaut blood may not act weird in space after all


astronauts' blood changes in space — but that may not stop them from getting to mars.  spacex founder elon musk often boasts about the imminent colonization of mars, despite major human health problems that stand between us and the red planet. fortunately for musk and other aspiring space travelers, nasa scientists may have crossed one item off that list of potential problems.  researchers who study space health have long thought astronauts lose red blood cells during extended deployments in space, leading to anemia. the ailment causes fatigue, lightheadedness, shortness of breath and other issues. but a new study shows that astronauts might not be anemic at all while in space — instead, it's a condition that develops when they land. the finding could mean more time safely spent in space,

despite trump's request, nasa not aiming for crewed mars mission by 2024


donald trump won't be president when nasa launches its first crewed mission to mars. during a call with nasa astronauts aboard the international space station (iss) last month, trump said he'd like the space agency to get people to the red planet "during my first term or, at worst, during my second term." such a request would seriously accelerate nasa's "journey to mars" initiative, which is currently working to get astronauts to the vicinity of the red planet in the 2030s. but it now appears that trump was just engaging in a playful back-and-forth with iss astronauts peggy whitson and jack fischer, not stating a serious policy objective.

how fit will astronauts be after years in space?


after spending months or years in space during future long-term missions, returning to earth can be challenging for astronauts — and one set of researchers is finding out just how challenging using a life-size spacecraft model.  using a mock-up of nasa's orion spacecraft, scientists monitored the health and fitness levels of "astronauts" as they performed emergency escape maneuvers, simulating what crews undergo during their return to earth. "maintaining astronaut health is critical to nasa missions, and we need to be able to keep astronauts safe in flight and during landing," carl ade, assistant professor of exercise physiology at kansas state university, said in a statement.

trump wants to send astronauts to the moon on the way to mars


the trump administration had previously signaled its intentions to send astronauts back to the moon, but now that renewed space exploration objective is official. on monday, the president signed space policy directive 1, a document detailing a shift in u.s. policy that would reprioritize a mission to put american boots on the moon for the first time in 45 years.while mars is widely considered to be the primary goal of much current space exploration, a moon mission would “establish a foundation for an eventual mission to mars,” president trump asserted during the signing.“the directive i am signing today will refocus america’s space program on human exploration and discovery. it marks a first step in returning american astronauts to the moon for the first time since 1972, for long-term expl

at mars conference, experts discuss threats to space travelers


space will never be a risk-free environment, but there are ways to reduce the risk for crew who travel on future deep-space missions, experts noted at the human to mars summit in washington, d.c., yesterday (may 9). for example, nasa could help to prepare crewmembers for the challenges they might face on longer missions by first doing missions closer to home, according to the experts on the panel, which was moderated by space.com columnist leonard david. indeed, nasa is already using the international space station (iss) as an environment for learning how to reduce the risks associated with a potential human mission to mars, john grunsfeld, associate administrator for nasa's science mission directorate and a former astronaut, said during the discussion. however, people outside the spacefli

'astronauts' complete simulated mission in hawaii


after spending eight months simulating life on mars on the slopes of the mauna loa volcano, six "astronauts" emerged from their hawaiian habitat on sunday (sept. 17) to return to civilization.  this concluded the fifth mock mars mission of the nasa-funded hi-seas program (hawaii space exploration analog and simulation). operated by the university of hawaii, this research project studies how groups of interplanetary travelers would work together on long-term missions while in cramped quarters.  during the mission, four men and two women lived in isolation from the rest of planet earth and could eat only shelf-stable foods and occasional lab-grown vegetables. when communicating with the outside world, they had to deal with the 20-minute delay that astronauts on mars would experience as well.

how vintage rocket tech could be nasa's ticket to mars and beyond


dangerous radiation. overstuffed pantries. cabin fever. nasa could sidestep many of the impediments to a mars mission if they could just get there faster. but sluggish chemical rockets aren't cutting it — and to find what comes next, one group of engineers is rebooting research into an engine last fired in 1972. the energy liberated by burning chemical fuel brought astronauts to the moon, but that rocket science makes for a long trip to mars. and although search for a fission-based shortcut dates back to the 1950s, such engines have never flown. in august, nasa boosted those efforts when the agency announced an $18.8-million-dollar contract with nuclear company bwxt to design fuel and a reactor suitable for nuclear thermal propulsion (ntp), a rocket technology that could jumpstart a new er

mars crater offers reminder of apollo moonwalk


two craters on two different worlds that were visited by two nasa missions have now been linked to mark the 45 years between the two explorations. nasa's mars rover opportunity, which has been driving on the red planet since 2004, passed by a young crater this past spring during the 45-year anniversary of the apollo 16 moon landing. the intersection inspired the rover's science team to informally name the martian feature after the lunar mission's lander. "orion crater" on mars honors the apollo 16 lunar module orion, which carried john young and charles duke to and from the surface of the moon in april 1972.

why a mars dirt sample probably wouldn't be sent to the space station

nasa lab gets space radiation upgrade for mars mission research


new upgrades to a nasa radiation laboratory will let researchers explore the deadly environment astronauts encounter beyond earth's magnetic field. radiation is the silent killer of space exploration. astronauts can't sense their exposure to it, and over time it can lead to problems such as cancer or heart disease. before humans can venture to mars — a mission that nasa hopes to start in the 2030s — scientists will need to figure out how to protect the travelers on their long journey. martian astronauts will be unprotected by earth's magnetic field, and therefore exposed to galactic cosmic radiation from charged particles (ions) emanating out of supernova explosions. they also will receive radiation doses from the sun — especially during coronal mass ejections that often happen with solar
