‘Martian Plague’: Bringing Mars Samples to Earth May Cause a Devastating Pandemic, Scientists Warn

– April 30, 2021

While Perseverance rover is rolling over the Red Planet studying its geology and taking fancy selfies with the help of the Ingenuity helicopter, researchers back on Earth are looking forward to welcome and investigating the first Martian soil samples in the upcoming years.

Bringing rocks from the Marian surface to Earth does not seem very exciting to a small group of enthusiasts from The International Committee Against Mars Sample Return (ICAMSR), who warn about incredible risks these life-bearing samples may pose to our home planet, including an immense “Martian plague”.

The National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) are working together on The Mars Sample Return Campaign in an effort to bring precious rocks and soil to Earth for detailed tests. They plan to launch a lander in 2026 to pick up samples collected by the Perseverance rover which landed on the Red planet in February. So the Martian soils – including some micro-organisms which potentially inhabit them – may end up on our planet in the next decade.

According to NASA, “returning pristine samples of Mars to Earth has been a goal for generations of planetary scientists.”

Dr. Gilbert Levin is not very enthusiastic about this. The engineer, who was the one investigating NASA’s Viking programme, which ran from 1975 to 1983, told the Daily Star that there is a “real chance” the Red Planet is inhabited by life forms that would leak to Earth, potentially causing a new, devastating pandemic from which we have no defense.

“I fear that, even if a safe Mars Sample Return container could be made and brought to Earth, there is a good probability that some of the sample would escape from the ‘secure’ lab where the container would be opened,” Levin says.

Scientists from ICAMSR express a similar caution, citing legendary astronomer Carl Sagan, who warned about the consequences of the sample-bringing in his 1973 book:

“Precisely because Mars is an environment of great potential biological interest, it is possible that on Mars there are pathogens, organisms which, if transported to the terrestrial environment, might do enormous biological damage…a Martian plague.”

Solar cycle 25: the Sun wakes up

Space Daily – October 30, 2020

The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetized plasma emanating from its surface. This quiet period is known as the solar minimum, but things are starting to heat up again.

Experts on the Solar Cycle 25 Prediction Panel recently announced that the Sun has officially entered a new cycle, its 25th since we’ve had enough data to reliably recognize them. While we can expect space weather to get more exciting in the next few years, with peak sunspot activity expected in 2025, the panel came to the consensus that this next cycle will be very similar to the previous, both generally weaker than the average solar cycle.

“While small and medium-sized solar storms are more likely during peak solar activity,” explains Juha-Pekka Luntama, Head of ESA’s Space Weather Office, “it is important to remember that individual large solar events, huge flares and coronal mass ejections, can happen at any point, independent of where we are in the solar cycle or how strong the cycle becomes.”

If such solar storms impact Earth, they can create geomagnetic storms in our magnetosphere. While good news for aurora hunters, these storms can disrupt and even damage power grids on Earth and satellites in orbit, and the vital services they provide.
