This week’s image comes from NASA showing a Dragon cargo ship approaching the International Space Station (ISS) earlier this month with supplies for the Expedition 68 crew. In this photo, the Dragon is above the Indian Ocean near Madagascar.

It is an amazing image each and every time. What a workplace and what a view. Telework just isn’t the same.

Pic of the Week: Martian Sample Depot

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.)

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.

ChatGPT: Imagining a Future Press Release About CERES

I was playing with ChatGPT recently and asked it to create a NASA press release that would be issued if we ever found life on the dwarf planet Ceres. I wanted to see what it would create. Here it is:

NASA Press Release: NASA Discovers Possible Signs of Life on Ceres

NASA scientists studying data from the Dawn spacecraft have discovered evidence of possible life on Ceres, one of the largest objects in the asteroid belt between Mars and Jupiter. The discovery was made possible through the use of sophisticated instruments on the spacecraft, which has been orbiting Ceres since 2015.

The data collected by Dawn suggests the presence of complex organic molecules on the surface of Ceres, which are often associated with the presence of life. In addition, scientists have detected the presence of hydrothermal vents on the ocean floor of Ceres, providing further evidence of the potential for life on this small world.

“We are excited to announce that we have discovered evidence of possible life on Ceres,” said NASA Administrator Bill Nelson. “This discovery is a testament to the ingenuity and hard work of the scientists and engineers involved in the Dawn mission, and it opens up a whole new world of possibilities for astrobiology.”

The discovery of possible life on Ceres is significant because it suggests that life may be more common in the universe than previously thought. It also has important implications for future exploration of our solar system and beyond.

“We have always been fascinated by the possibility of finding life beyond Earth,” said Dr. Thomas Zurbuchen, Associate Administrator for the Science Mission Directorate at NASA Headquarters in Washington. “This discovery gives us new hope that we may not be alone in the universe, and it underscores the importance of continuing to explore our solar system and beyond.”

The Dawn spacecraft is currently in its final orbit around Ceres and will continue to collect data for as long as its instruments remain operational. NASA scientists are also planning future missions to Ceres to further study the potential for life on this small world.

It’s a fun fictional piece that builds on some real information, though it has its weak points. Here are some of my observations:

  • Spacecraft Information – Outdated: NASA lost contact with the Dawn spacecraft in November 2018, so a recent finding like this is unlikely unless it was buried in earlier data still being studied. The press release later states that the Dawn spacecraft is in its final orbit and still collecting data. While the spacecraft might remain in orbit for decades to some, its mission is over, as NASA noted when it stated: “Dawn spent every last drop of hydrazine making science observations of Ceres and radioing them back so we could learn more about the solar system we call home.”
  • Scientific Information – Good Speculation: Ceres does have hydrothermal vents that some have speculated could harbor life.
  • People – Actual Officials: The two NASA officials quoted are real officials – Administrator Bill Nelson and Dr. Thomas Zurbuchen, Associate Administrator for the Science Mission Directorate – saying the sorts of things you would expect people in their positions to say.

Overall, it is a good demonstration of what these chat bots can do – piece together a credible enough summary to keep you guessing. Just don’t post this anywhere without full context. I do not want to start any rumors.

Space Mission: ESA’s Juice Mission

On April 13th, the European Space Agency (ESA) will launch its Jupiter Icy Moons Explorer (Juice) mission from French Guiana. The purpose of the mission is to conduct a detailed study of Jupiter as well as three of its moons (and their oceans) – Ganymede, Callisto and Europa. The spacecraft will eventually go into orbit around Ganymede, which will be the first orbit of a moon in our solar system other than Earth’s Moon.

The key milestones for the mission are listed below and shown in greater detail within the graphic as well:

February 2023: Juice arrives in French Guiana

April 13, 2023: Launch on Ariane-5 rocket

July 2031: Arrival at Jupiter

-July 2031 – November 2034: 35 icy moon flybys

December 2034: Arrival at Ganymede

In addition to ESA/European scientific instruments and equipment, the spacecraft will also carry items from NASA, the Japan Aerospace Exploration Agency, and the Israel Space Agency.

The delayed arrival at Jupiter relates to the need for multiple flybys cover this great distance. In The Financial Times, Justin Byrne, head of science for lead contractor Airbus, stated, “Ariane-5 is a very powerful rocket but it can only give us about half the energy we need to get to Jupiter…We get the rest by doing planetary fly-bys, each one giving us a gravitational assist through a slingshot manoeuvre.”

The ESA put together a useful Launch Kit that answers any question you may have about the Juice mission, as well as related missions.
