Bunchek, who also works on NASA’s space agriculture projects including the Vegetable Production System Veggie that provides fresh greens to astronauts on the International Space Station, has grown a range of leafy greens, herbs and fruits at the EDEN ISS greenhouse including cucumbers, tomatoes, lettuce, basil and mint. The greenhouse, operated by the German Aerospace Centre DLR, tests advanced technologies that might be used in the future to grow food on the Moon and Mars.

Tereza Pultarova The Earth twin of ExoMars Rosalind Franklin heads for Mars yard Crew-2 shares the space station with members of the Soyuz MS-18 mission, Russian cosmonauts Oleg Novitsky and Pyotr Dubrov, and NASA astronaut Mark Vande Hei, who arrived on April 9. Together with his Crew-2 colleagues, NASA astronauts Shane Kimbrough and Megan McArthur, and Japan's Akihiko Hoshide, he will stay at the station until late October this year. Pesquet arrived at the orbital outpost on board of SpaceX Crew Dragon Endeavour on April 24. "This is a sight I’ll remember all my life." "Crazy to think that six hours after we closed the hatch on our friends, we saw them in that shooting star streaking through the night sky," Pesquet wrote on Twitter where he posted the image. The picture was taken by the European Space Agency (ESA) astronaut Thomas Pesquet from aboard the International Space Station on May 2, shortly before the capsule splashed down in the Gulf of Mexico. Monday, May 10, 2021: The Crew Dragon capsule Resilience leaves a fiery trail above Mexico as it hurtles through Earth's atmosphere, returning four astronauts, members of the Crew-1 mission, to Earth after more than five months in space.

The frequency and scale of wildfires increases due to the rising temperatures and frequent draughts. Wildfires are part of the vicious cycle of climate change. Those “zombie fires” have reawaken in the approaching spring despite freezing temperatures as low as minus 60 degrees Fahrenheit (minus 50 degrees Celsius). Many of the current fires probably started in 2020 and survived the winter smouldering in the peats.
Since the beginning of 2021, more than 400 forest fires have been reported with the regions of Tyumen, Omsk and Novosibirsk especially badly affected, according to the Russian Federal Forestry Agency. Siberia has been plagued with wildfires for several years. Wednesday, May 12, 2021: The European Sentinel 2 satellite captured a fire cloud generated by a blazing wildfire near the town of Oymyakon in north-eastern Siberia, close to the Arctic circle, on May 2. Tereza Pultarova Sun sets above Jezero Crater Juno originally observed the spot in June 2020, only two weeks after Foster’s discovery. Twice as wide and three times as long as the original spot, the evolved feature might persist for an extended period of time, the scientists believe. The images, captured by the JunoCam camera, reveal that the remnants of Clyde’s Spot had drifted away from the Great Red Spot and developed into a complex structure that scientists call a folded filamentary region. Juno flew over the area during its 33rd close pass on April 15 at a distance of about 16,800 miles (27,000 kilometers) from the top cloud layer. Named after its discoverer, retired engineer and avid sky-watcher Clyde Foster, the plume of cloud erupting above the gas giant’s atmosphere southeast of the famous Great Red Spot, has undergone substantial changes since its discovery in May last year. Thursday, May 20, 2021: NASA’s Juno mission captured images of Clyde’s Spot, a new feature in the atmosphere of Jupiter, first observed last year by an amateur astronomer in South Africa.
