Scientists Fear Mars Trip Could Be a
Suicide Mission (Source: Business Insider)
Going to Mars may be more dangerous than we thought. The major problem
is high-energy space radiation. Scientists know that cosmic rays can
damage DNA. They had just overlooked how bad it could get. A team
re-examined how damaged DNA can cause cancer. They then estimated
levels of radiation exposure in space and on Mars. Their results are
devastating. The risk of cancer on Mars is twice as high as previously
thought.
It comes down to how damaged DNA spreads throughout the body. A
detailed study in mice reveals a sinister side to radiation. Damaged
DNA doesn't just keep to itself. It sends signals to nearby healthy
cells, which triggers the healthy cells to mutate, which could cause
more cancer. Previous models hadn't accounted for this domino effect.
Even radiation shielding only moderately reduces the risk. Luckily on
Earth, we're protected from this danger. (6/20)
Slowdown in Satellite Orders Triggers
Layoffs at Space Systems Loral (Source: Space News)
Citing a long-term drought in satellite orders, Space Systems Loral has
laid off a number of employees at its California satellite
manufacturing facility. SSL President John Celli said an “extended
slowdown” in orders for geostationary orbit communications satellites
led the company to this round of layoffs. “With fewer satellites coming
into the factory we have to make reductions to remain competitive.”

Buzz Aldrin is obsessed with Mars. The second human to walk on the moon
is now developing a plan to send humans to live permanently on the red
planet. The Buzz Aldrin Space Institute at Florida Tech is hoping to
fine-tune that vision with research and workshops with experts. Buzz
Aldrin’s son, Andy Aldrin, is the Director of the Institute. He spoke
with 90.7’s space reporter Brendan Byrne about the sociological
challenges of living on Mars. Click here.
