Peru, 15 March, 2017: When humans finally land on Mars one of the first dishes made of locally grown vegetables may be the universally popular French fries.

Researchers from the International Potato Center and the University of Engineering and Technology in Lima, Peru, say potatoes could grow in Martian soil, if they are given certain nutrients and water.

NewsGram brings to you top news around the world today.

Researchers successfully grew potatoes in soil from the Pampas de La Joya desert in Peru, which they say is the closest chemically to the dry Martian soil.

 Helped by scientists from NASA Ames Research Center, they built a special chamber closely mimicking the Martian temperature, air pressure, and oxygen and carbon dioxide levels.

Another Space Telescope Shuts Down: NASA

Launched by space shuttles in the 1990s, Hubble and Chandra are part of NASA's Great Observatories series.

Second Space Telescope Shuts Down, NASA Says Pixabay

Another NASA space telescope has shut down and halted science observations.

Less than a week after the Hubble Space Telescope went offline, the Chandra X-ray Observatory did the same thing. NASA said Friday that Chandra automatically went into so-called safe mode Wednesday, possibly because of a gyroscope problem.

Hubble went into hibernation last Friday because of a gyroscope failure.

Both orbiting observatories are old and in well-extended missions: Hubble is 28, while Chandra is 19. Flight controllers are working to resume operations with both.

NASA said it’s coincidental both went “asleep” within a week of one another. An astronomer who works on Chandra, Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, tweeted Friday that “Chandra decided that if Hubble could have a little vacation, it wanted one, too.”

Launched by space shuttles in the 1990s, Hubble and Chandra are part of NASA’s Great Observatories series. The others are the Compton Gamma Ray Observatory, which was also launched in the 1990s but eventually failed and was destroyed, and the Spitzer Space Telescope, launched in 2003 and still working. Each was intended to observe the cosmos in different wavelengths. (VOA)
