Shrouded in clouds today in 1969, this image was taken by the crew of Apollo 10 as they began their lunar journey. From 36,000 nautical miles away, this full disk view of our home planet shows the crew’s vantage point from space.

The crew members on Apollo 10 were astronauts Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene E. Cernan, lunar module pilot. Astronaut Young remained in lunar orbit, in the Command and Service Module (CSM) “Charlie Brown”, while astronauts Stafford and Cernan descended to within nine miles of the lunar surface, in the Lunar Module (LM) “Snoopy”.

What’s up in the night sky this May? Jupiter climbs higher in the southeast sky earlier in the evening this month. This means that telescope viewers don’t need to wait until midnight to get good views of the planet. You can enjoy Jupiter through binoculars too! Saturn is now visible before midnight, rising around 11:30 p.m. early in the month and by 9:30 p.m. later in the month. The best time to see Saturn is when it’s highest in the sky, that’s after midnight this month and before midnight in June. Through a telescope, you may even see some of Saturn’s cloud bands!Check it out…

Heat Below the Icy Surface of Enceladus: A new study in the journal Nature Astronomy reports that the south polar region of Saturn’s icy moon Enceladus is warmer than expected just a few feet below its icy surface. This suggests that Enceladus’ ocean of liquid water might be only a couple of miles beneath this region — closer to the surface than previously thought.

The excess heat is especially pronounced over three fractures that are not unlike the “tiger stripes” — prominent, actively venting fractures that slice across the pole — except that they don’t appear to be active at the moment. Seemingly dormant fractures lying above the moon’s warm, underground sea point to the dynamic character of Enceladus’ geology, suggesting the moon might have experienced several episodes of activity, in different places on its surface. “What is the warm underground ocean really like and could life have evolved there? These questions remain to be answered by future missions to this ocean world,” said Cassini Project Scientist Linda Spilker at NASA’s Jet Propulsion Laboratory, Pasadena, California.

Space ravioli? No, it’s Saturn’s moon Pan. These raw, unprocessed images of Saturn’s tiny moon, Pan, were taken on March 7 by our Cassini spacecraft. The flyby had a close-approach distance of 24,572 kilometers (15,268 miles).
These images are the closest images ever taken of Pan and will help to characterize its shape and geology.

Engineers successfully tested the parachutes for our Orion spacecraft at the U.S. Army Yuma Proving Ground in Arizona Wednesday. This was the second test in a series of eight that will certify Orion’s parachutes for human spaceflight. The test, which dropped an Orion engineering model from a C-17 aircraft at 25,000 feet, simulated the descent astronauts might experience if they have to abort a mission after liftoff.
Orion, which will launch atop our new Space Launch System rocket, is built to take astronauts farther into the solar system than ever before. The spacecraft will carry crew to space, provide emergency abort capabilities, sustain the crew during their mission and provide safe re-entry through Earth’s atmosphere.

Video by @babaktafreshi, The World at Night photography. A weekend trip to the #moon can be an actual travel plan by the end of the century! If it was possible, it would take 16 days for a today airliner to reach the moon non-stop (better to be!) at top speed. And 5 months for a car at highway speed of 70 mi/h. For the #Apollo astronauts it took 3-4 days. Several space tourism companies are planning for tours to the moon by 2030s with a spacecraft that loops around the Moon on a circumlunar trajectory (no landing) and returns to Earth, at estimated cost of ~ $100 million per seat, includes months of ground-based training. From my collection. Follow @babaktafreshi for more of #astronomy #space & #nightsky stories. @natgeocreative @natgeo #solarsystem #spacetravel
