Space-grown lettuce could help astronauts avoid bone loss
NASA is preparing to send humans to Mars sometime in the 2030s. The 3-year mission will expose astronauts to a long period of microgravity, which will cause them to lose bone mass. But now, scientists report transgenic lettuce that produces a bone-stimulating hormone. Someday, astronauts could grow the lettuce in space and help guard against bone loss—simply by eating a big bowl of salad. In addition, the lettuce might help stave off osteoporosis in resource-limited areas here on Earth, the researchers say.
The researchers will present their results today at the spring meeting of the American Chemical Society (ACS).
Previous studies of astronauts on extended space missions have shown that they lose, on average, more than 1% of bone mass per month spent in space, a condition known as osteopenia.
Micro-geostationary satellite enters design phase
A small but powerful European telecommunications satellite – the first of a series – is to be developed under a contract signed between ESA and SWISSto12, an innovative company based in Renens, Switzerland.
Watch live: first space steps for Matthias

Cosmic milestone: NASA confirms 5,000 exoplanets
The count of confirmed exoplanets has just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes.
Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system.
Satellite operator OneWeb switches launches to SpaceX
Global satellite communications company OneWeb said Monday that it will switch launches to Elon Musk's SpaceX, after suspending activities with Russia's Baikonur Cosmodrome in Kazakhstan.
"OneWeb... announced today that the company and SpaceX entered into an agreement that will enable OneWeb to resume satellite launches," OneWeb said in a brief statement.
The terms of the agreement remai Samantha’s second space mission: Minerva

ESA astronaut Samantha Cristoforetti will return to the International Space Station in April 2022. Her second space mission is known as Minerva.
Inspired by Roman mythology, Samantha says the Minerva mission name and patch pay homage to the competence and sophisticated craftmanship of all those who make human spaceflight possible.
Samantha will travel to the Station alongside NASA astronauts Kjell Lindgren, Bob “Farmer” Hines and Jessica Watkins. Collectively known as Crew-4, the astronauts will be launched from NASA’s Kennedy Space Center in Florida, USA, on a SpaceX Crew Dragon spacecraft.
When Samantha arrives at the Station, her Minerva mission officially
Methane detected over Poland’s coal mines
Data from the Tropomi instrument onboard the Copernicus Sentinel-5P satellite has been used to detect methane plumes over some of Europe’s largest methane-emitting coal mines.
Surviving space: major conference focuses on materials in space environment
Materials make the space mission – but ensuring they survive in space is always a challenge. The very act of transporting them beyond Earth ensures their characteristics will alter as they interact with the space environment in complex ways.
SpaceX launches 53 Starlink satellites after weather delays
Elon Musk's SpaceX launched 53 Starlink satellites from Florida early Saturday morning after the launch was postponed Friday night because of stormy weather.
The launch, which came days after the company celebrated its 20th anniversary, was pushed back to 12:42 a.m. EDT when stormy weather near Complex 40 at Cape Canaveral Space Force Station had cleared.
