The second all-private astronaut mission to the space station …
Completing the set of tiny severe weather trackers …
And a robotic explorer – with a twist …
A few of the stories to tell you about – This Week at NASA!
Second Private Astronaut Mission to the Space Station
On May 21, a SpaceX Dragon spacecraft launched from NASA’s Kennedy Space Center on Axiom Mission 2, the second all private astronaut mission to the International Space Station.
The four-person crew, commanded by former NASA astronaut Peggy Whitson, is scheduled to spend several days conducting research, outreach, and commercial activities on the space station.

Final Pair of Storm-Observing CubeSats Launched
The final two CubeSats for NASA’s TROPICS mission launched from Rocket Lab’s Launch Complex 1 in New Zealand on May 26. The small satellites will join two other identical spacecraft that launched to orbit earlier this month.
All four will fly, as a constellation, in a unique low Earth orbit that will allow them to observe tropical cyclones, including hurricanes and typhoons, more often than what is possible with
current weather satellites.

Designed to sense its environment, calculate risk, travel, and gather data without real-time human input, EELS could eventually explore destinations throughout the solar system.

Autonomous Snake-Like Robotic Explorer
A team at NASA’s Jet Propulsion Laboratory is creating and testing a snake-like robot called EELS, short for Exobiology Extant Life Surveyor. The self-propelled, autonomous robot is
being developed to go where other robots can’t go.
Although it was inspired by a desire to look for signs of life in the sub-surface ocean on Saturn’s icy moon, Enceladus, EELS is not currently part of any NASA mission.

NASA completed a crucial hot fire test of the RS-25 engine, part of a 12-test certification series for future Artemis missions. This achievement brings NASA one step closer to landing the first woman and person of color on the Moon, as well as establishing a long-term lunar presence. Credit: NASA / Stennis
Artemis Rocket Engine Test Series Continues
On May 23, NASA’s Stennis Space Center conducted a hot fire test of an RS-25 rocket engine. It was the eighth hot fire of the current 12-test series to certify production of new RS-25s.
Four of the engines will help power NASA’s Space Launch System rocket on future Artemis missions to the Moon.
That’s what’s up this week @NASA.
