Space Age Lettuce Could Counter Astronaut Bone Loss

It’s hard to imagine anyone being more excited about eating lettuce than the three astronauts aboard the International Space Station (ISS) were yesterday, when they tucked into the first leaves of space-grown lettuce they’ve been allowed to eat. Despite having to sanitise the leaves first, with citric-acid-based, food-safe, antibacterial wipes (yummy!), they broke out the oil and vinegar and tucked in with gusto. They even thanked Mission Control and the scientists for giving them the opportunity to take part in this payload mission, and saved some veggies for the Russian cosmonauts who were outside on a spacewalk at harvest time.

While we’re waiting for Tim Peake to blast off to the International Space Station (ISS) to begin his Principia mission, I thought it might be fun to have a look at the first Briton in space – Helen Sharman, who was also the first woman to visit the Mir space station, in 1991.

One of the nerdy things I enjoy doing in my spare time is researching the first seeds to have made it into space. This is what I have found so far:

From the moment humans started to reach for the skies, we have used other species from Earth to test what’s safe and what happens to life away from its natural habitat on the planet’s surface.

In this episode, Emma recaps important spacecraft Arrivals and Departures and learns about growing nutrients and medicines in space. There’s a new plant experiment running on the International Space Station, and exciting news from ESA.

Just over 3 weeks ago, I started the AeroGarden on its latest mission – rooting herb cuttings. Unsurprisingly, the mint was the first plant to take root, which it did in under a week.

I imagine the Apollo 11 astronauts had plenty to do while they were hurtling towards the Moon, but from a bystander’s perspective it was probably pretty dull stuff. Still, it’s Day 3 of the mission, so let’s have a look at what they’ve got stashed away in their space age picnic basket.

In this NASA image from January 2020, you can see Lashelle Spencer taking measurements on ‘Red Robin’ dwarf tomato plants. Lashelle is a plant scientist at NASA’s Kennedy Space Center in Florida, and this photo was taken inside the Plant Processing Area in the spaceport’s Space Station Processing Facility.

At the beginning of the year, I set up a new mission in the AeroGarden, growing two peppers (Popti and Redskin) and a tomato (Veranda Red). Ten days later, I had two tomato seedlings, which I had to thin to one. The peppers were a bit slower, but by 19th January they had germinated (and been thinned) too.

Back in 2014, I bought some seeds that had been into space. They are cinnamon basil (Ocimum basilicum Cinnamon), still sealed into their space packet.
