This week’s image shows the Perseverance Mars rover looking back on its work – the depositing of 10 titanium sample tubes on the surface of the Red Planet should they be needed as backups (see image below marking the sample locations). The rover is carrying the official samples, but this depot was set up just in case something happens to the rover.

Here is a little more from NASA:

Eight of those tubes are filled with rock and regolith (broken rock and dust), while one is an atmospheric sample and one is a “witness” tube...

The depot represents a backup collection of samples that could be recovered in the future by the Mars Sample Return campaign, a joint effort between NASA and ESA (European Space Agency) that aims to bring Mars samples to Earth for closer study. The rover began building the depot on Dec. 21, 2022, precisely spacing the tubes in case they need to be retrieved at a future date.

The primary tubes reside in the belly of Perseverance, which would pass them, along with future samples taken during the mission to a Sample Retrieval Lander as part of the campaign. If anything were to happen to the rover to prevent it from delivering tubes directly to the lander, samples could be retrieved from the depot instead. (Learn more about all 18 samples taken so far.)

Space Stories: Possible Starship Launch, South Korean Rocket Test, and Massive Early Stars

Here are some recent stories of interest.

—Forbes: “Elon Musk Gets More Specific About Starship’s First Rocket Launch to Space“

We’ve been waiting for nearly two years to see Elon Musk’s big rocket blast off again, and now the SpaceX founder is starting to narrow the targeted time frame for Starship’s first orbital attempt. The controversial entrepreneur said on Twitter last week that the next generation vehicle destined to take astronauts to the moon and perhaps start a civilization on Mars “will be ready to launch… in a few weeks, then launch timing depends on FAA license approval.”

—Space News: “South Korea’s Innospace Succeeds in Test Launch“

South Korean rocket startup Innospace successfully launched a suborbital rocket from Brazil over the weekend, demonstrating a hybrid motor it plans to scale up into a small orbital launch vehicle. The launch of Innospace’s HANBIT-TLV suborbital rocket took place March 19 from the Alcântara Space Center, and the company called the flight a success, although it did not disclose the rocket’s peak altitude. 

—Space.com: “The Early Universe was Crammed with Stars 10,000 Times the Size of our Sun, New Study Suggests“

The first stars in the cosmos may have topped out at over 10,000 times the mass of the sun, roughly 1,000 times bigger than the biggest stars alive today, a new study has found. Nowadays, the biggest stars are 100 solar masses. But the early universe was a far more exotic place, filled with mega-giant stars that lived fast and died very, very young, the researchers found.

Blast from the Past: Adventures on Mars

Back in 2016, NASA put a few fun posters online advertising opportunities on Mars. The posters were originally originally commissioned by NASA to be part of an exhibit at the Kennedy Space Center Visitor’s Complex in 2009.

Visit the NASA poster site if you want the files for these images and others. They are great for framing, note cards, or post cards.

Here are some recent stories of interest.

—SpaceNews: “NASA Mars Orbiter Reveals China’s Zhurong Rover Has Not Moved for Months“

Images from NASA’s Mars Reconnaissance Orbiter reveal that China’s Zhurong rover remains stationary on the Red Planet as China remains silent on the status of its spacecraft. The High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO) captured images of the rover on March 11, 2022, a second on Sept. 8, 2022 and finally Feb. 7, 2023. The images were published Feb. 21 by the HiRISE Operations Center.

—Los Angeles Times: “Space Telescope Spots Massive Galaxies Near Cosmic Dawn and Blows Astronomers’ Minds“

Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the big bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters.” While the new James Webb Space Telescope has spotted even older galaxies, dating to within a mere 300 million years of the beginning of the universe, it’s the size and maturity of these six apparent mega-galaxies that stunned scientists. They reported their findings Wednesday in the journal Nature.

—Newsweek: “Russian Rocket Crashes Back Into Russia After 42 Years“

A decades-old Soviet era piece of space junk has crashed back to Earth after over 40 years in orbit, improbably crash landing back in its home country, Russia. The abandoned Soviet Vostok-2M Blok E rocket stage, weighing more than 3,000 pounds, “made an uncontrolled reentry over Novaya Zemlya at 1016 UTC Feb 20 after 42.7 years in orbit,” tweeted Jonathan McDowell, an astrophysicist and group leader at the Chandra X-ray Center Science Data Systems.

Martian Climate in New England

With all of the excitement last week regarding Chinese balloons, which is continuing into this week with two “unidentified object” incidents in Alaska and Canada, I forgot to mention the -108 F wind chill temperature at the top of Mount Washington in New Hampshire on February 3rd. The Washington Post reported that this may be the lowest temperature ever reported in U.S. history.

In fact, the Mount Washington temperature was lower than the temperature experienced that day by the Curiosity rover in Gale Crater on Mars. It is still autumn in the crater, so temperatures could still fall to -225 F during winter. Let’s not try that in New Hampshire.

Europe may be complaining about the unusually warm mountain temperatures this year, but you will not hear this talk from the Yankees up north. They are getting the full Martian treatment and staying close to their wood stoves.
