ESA’s Jupiter Icy Moons Explorer (Juice) Gets Wings – SciTechDaily

The images were taken by Juice monitoring camera 1 (JMC1), which is located on the front of the spacecraft and looks diagonally up into a field of view that will eventually see deployed antennas, and depending on their orientation, part of one of the solar arrays. Because of the acute viewing angle of the camera, only part of the array is seen, in this case part of the distinctive cross-shape pattern of one of the solar panels.
The first image was taken at 15:28 CEST during solar array panel deployment. The second image was taken at 15:32 CEST, and shows the panels having rotated into their 70 degree position, just a few seconds before the deployment sequence was confirmed to have completed.
The lighting conditions are challenging in this scene, with the side of the array causing a bright reflection.
Each of the two ‘wings’ comprise five 2.5 x 3.5 m panels with a total area of 85 square metres. In total they span 27 m tip-to-tip, and are crucial to provide the necessary power to run the spacecraft and operate the science instruments once exploring the Jupiter system, where sunlight is 25 times weaker than on Earth. Their deployment, completed at 15:33 CEST, was critical to the success of the mission.
JMC images provide 1024 x 1024 pixel snapshots. The images shown here are lightly processed with a preliminary colour adjustment.
How to watch the Axiom-2 mission depart from the ISS on Tuesday
This Tuesday, the crew of the second-ever all-private mission to the International Space Station will be returning to Earth. The Axiom 2 or Ax-2 mission launched last week and saw private astronauts Peggy Whitson, John Shoffner, Ali Alqarni, and Rayyanah Barnawi traveling to the ISS on a SpaceX Crew Dragon launched from the Kennedy Space Center in Florida.
Now, the crew of four will be traveling back to Earth in the same Crew Dragon, and NASA will be livestreaming the departure of the spacecraft from the station. A separate stream will also be available showing the Crew Dragon splashing down off the coast of Florida. We’ve got the details on how to watch both below.
How to watch the mission departure
Coverage of the departure of the Crew Dragon from the ISS will begin at 9 a.m. ET (6 a.m. PT) on Tuesday, May 30. NASA will show a short introduction before the closing of the hatch of the station’s Harmony module at 9:10 a.m. ET (6:10 a.m. PT). There will then be a short break in coverage, which will resume at 10:45 a.m. ET (7:45 a.m. PT) to show the undocking of the Dragon at 11:05 a.m. ET (8:05 a.m. PT), with coverage ending 30 minutes after undocking.
You can watch the livestream of the hatch closing and the undocking on NASA’s YouTube channel, or by using the video embedded near the top of this page.
The crew will then travel back to Earth throughout Tuesday and into Wednesday, May 31. When the Crew Dragon is approaching Earth for splashdown, you’ll be able to tune into a livestream from Axiom Space. That will be available on Axiom’s website, but the company has not yet confirmed the exact time that coverage is expected to begin on Wednesday. You can find the latest updates on Axiom Twitter.
What to expect from the mission departure
The Ax-2 crew will have spent 10 days in space before heading home, and they will be bringing around 300 pounds of cargo back with them. The mission is notable for including the first two astronauts from Saudi Arabia, Ali Alqarni and Rayyanah Barnawi, as well as famous American astronaut Peggy Whitson who has spent more days in space than any other American or any other woman.
Axiom Space launched its first private mission to the ISS in April last year, with a third mission planned for November this year and a fourth planned for 2024.
NASA's New Horizons Spacecraft Captures ''Heart-Shaped'' Glacier On Pluto's Surface – NDTV
Space agency NASA routinely captures stunning images of our universe, leaving space lovers mesmerized. On Sunday, NASA shared a stunning image on Instagram taken by its New Horizons spacecraft showing a heart-shaped glacier on Pluto’s surface. The heart-shaped region is known unofficially as Tombaugh Regio and is made of nitrogen and methane.
The image was captioned as ”Absence makes the heart grow fonder. Our New Horizons spacecraft captured this heart-shaped glacier. It lies on Pluto’s surface, which also features mountains, cliffs, valleys, craters, and plains, thought to be made of methane and nitrogen ice ”
See the image here:
It described the image as ”Pluto’s surface is marked with cracks and craters in shades of brown. The partially visible heart appears in the lower right of the small world, which is surrounded by black space.”
New Horizons launched in January 2006 and reached Pluto in July 2015, flying within 7,800 miles of its surface, and becoming the first probe to fly by Pluto and its moons. The far-traveling spacecraft also visited a distant Kuiper Belt object Ultima Thule (2014 MU69) in January 2019.
Instagram users loved the picture and shared a variety of comments. One user wrote, ”Wouahh what a great capture, thanks to New Horizon spacecraft.” Another commented, ”For me, Pluto will always be a planet.”
A third said, ”Why is Pluto, not a plane? it literally has a heart!” A fourth added, ”Being afar doesn’t mean you aren’t part of the family.”
Pluto was once considered the ninth planet in the solar system, however, it was demoted in 2006 and reclassified as a dwarf planet. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet.
Pluto is slightly over 1,400 miles (2250 km) wide or about half the breadth of the United States or two-thirds the width of the Moon. With its average temperature of -387F (-232C) – Pluto’s surface is coated in ice made of water, methane, and nitrogen and is believed to have a rocky core and possibly a deep ocean.
This Week @NASA: Private Astronaut Mission, Autonomous Snake-Like Robot Explorer, TROPICS Launch – SciTechDaily
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 …

Second Private Astronaut Mission to the Space Station
On May 21, a <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="
” data-gt-translate-attributes=”["attribute":"data-cmtooltip", "format":"html"]”>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.
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 <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="

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.
