Webb has Arrived Safely at the Launch Site

Whew! A major milestone was achieved today in the James Webb Space Telescope’s journey towards launch. After the telescope successfully arrived in French Guiana yesterday following a secretive 16-day ocean journey (with apparently no pirates in sight), today the telescope took a short road trip over land to the ESA’s spaceport in Kourou. JWST is now at the payload processing facility, where staff will start the process of getting the telescope into the Ariane 5 rocket fairing.

Launch is currently scheduled for December 18, 2021 … T-66 days and counting!

‘Glowing’ Sand Dune Erosion on the Side of a Martian Crater

While Mars is known as the Red Planet, a variety of colors can be found on the planet’s surface. Just like on Earth, the array of colors we can see in images from Mars comes from the diverse minerals on or just under the surface.

In the case of this picture, subsurface minerals show up in gullies that have eroded down the side of a a giant sand dune.

James Webb’s 30 Days of Terror

It’s been a long and winding road getting the James Webb Space Telescope from concept to reality. And finally, after decades of planning, work, delays, and cost overruns, the next generation of space telescopes is finally ready to launch. But even now, as the telescope might be secretly traveling by cargo ship to the European Space Agency (ESA) launch site in French Guiana, everyone involved with the JWST project knows a successful launch isn’t the final victory.

In reality, post launch is when the real nail-biting begins. While the Mars rover teams undergo “Seven Minutes of Terror” to land their spacecraft on the Red Planet, the JWST teams will have more than 30 days of excruciating, slow-motion terror as the telescope embarks on its month-long-day, 1.5-million-kilometer (million-mile) journey out to the second Lagrange point (L2).

Russian Actor and Filmmaker are On the Space Station to Shoot Scenes for a Film

Earlier this week, a Soyuz spacecraft launched to the International Space Station with three people on board. But only one of them was a cosmonaut. The other two crew members were Russian actress Yulia Peresild and film producer Klim Shipenko. They will be on the ISS for 12 days to film scenes for an upcoming movie, called “Challenge.”

NASA says the film crew is there under a commercial agreement between Roscosmos and Moscow-based media entities, adding that “the launch will mark the expansion of commercial space opportunities to include feature filmmaking.”

NASA Spacecraft Takes a Picture of Jupiter … From the Moon

You know the feeling …. seeing Jupiter through your own telescope. If it gives you the chills — like it does for me — then you’ll know how the team for the Lunar Reconnaissance Orbiter felt when they turned their spacecraft around – yes, the orbiter that’s been faithfully circling and looking down at the Moon since 2008 – and saw the giant planet Jupiter with their camera. If you zoom in on the picture, you can even see Jupiter’s Galilean moons.

Here’s Perseverance, Seen From Space

The Mars Perseverance rover is on the move! The HiRISE camera on the Mars Reconnaissance Orbiter spotted the rover from above, the first view since shortly after the rover landed in February 2021. Perseverance appears as the white speck in the center of the image above, in the the “South Séítah” area of Mars’ Jezero Crater.

The HiRISE team said the rover is about 700 meters (2,300 feet) from its original landing site.

Earth has a new eye in orbit to monitor our changing planet.

Landsat 9 launched on September 27, 2021 continuing the Landsat family of satellite’s nearly 50-year tradition of making critical observations to help with energy and water management, forest monitoring, human and environmental health, urban planning, disaster recovery and agriculture.

No News Here, Just a Beautiful Globular Cluster Captured by Hubble. That is all.

Here’s some beauty for your timeline: a stunning and ancient globular cluster captured by the venerable Hubble Space Telescope. The telescope’s Wide Field Camera 3 and Advanced Camera for Surveys was used to take this picture of ESO 520-21 (also known as Palomar 6), which is located about 25,000 light years away from Earth. Scientists say this globular cluster is probably about 12.4 billion years old.

This is the Reactor That Could Make it Possible to Return From Mars

Remember when engineers proposed one-way trips to Mars, because round trips are just too expensive to bring people back to Earth again?

Getting people home from Mars can only happen in two ways. One is to lug all the return fuel with you when you launch from Earth, which is prohibitively difficult and expensive. The second way is to make the return fuel in-situ from Martian resources. But how?

A group of researchers from the University of Cincinnati propose using a type of reactor that was used from 2010-2017 aboard the International Space Station, which scrubbed the carbon dioxide from air the astronauts breathe and generated water to drink, with methane as a biproduct. On Mars, this reactor, called a Sabatier reactor, could take carbon dioxide from Mars’ atmosphere and create methane for fuel.

Chang’e-5 Returned an Exotic Collection of Moon Rocks

Scientists have begun studying the samples returned from the Moon by China’s Chang’e-5 mission in December 2020, and a group of researchers presented their first findings at the Europlanet Science Congress (EPSC) last week.

“The Chang’e-5 samples are very diverse, and includes both local and exotic materials, including some glutenates [sharp, jagged lunar particles], silicas, salts, volcanic glasses, and impact glasses, along with different minerals and different rock types,” said Yuqi Qian, a PhD student at the China University of Geosciences, during his presentation at the EPSC virtual meeting.
