SpaceX Falcon 9 rocket and more: Understand the world in 11 images

NASA/JPL-Caltech

NASA’s Ingenuity helicopter reached new heights on Mars as the ISS saw a successful experiment and new crew members the week of April 22–28.

Here are the week’s biggest science stories, told in 11 astounding images.

HI-SEAS

11. Cute but deadly

Nunes et al. PLOS ONE (2021)

April 28

Researchers identified a new species of highly poisonous Brachycephalus ephippium, or pumpkin toadlet, in Brazil. Members of the Brachycephalus species can be hard to identify, due to the slight differences between them.

10. Aiming for the stars

HI-SEAS

April 28

Scientists from HI-SEAS presented research on Hawaii’s lava tube at the European Geosciences Union General Assembly 2021. At the HI-SEAS research station, astronauts in training explore lava tubes in spacesuits to prepare for missions on Mars and the Moon.

3. Falcon 9 from above

Thomas Pesquet

April 25

Astronaut Thomas Pesquet captured the second stage of a Falcon 9 rocket on camera from aboard a Crew Dragon. The second stage had just detached after bringing the Crew Dragon to orbit.
