Here are some recent stories of interest.

—NASA JPL: “NASA’s Curiosity Rover Clocks 4,000 Days on Mars“

Four thousand Martian days after setting its wheels in Gale Crater on Aug. 5, 2012, NASA’s Curiosity rover remains busy conducting exciting science. The rover recently drilled its 39th sample then dropped the pulverized rock into its belly for detailed analysis. To study whether ancient Mars had the conditions to support microbial life, the rover has been gradually ascending the base of 3-mile-tall (5-kilometer-tall) Mount Sharp, whose layers formed in different periods of Martian history and offer a record of how the planet’s climate changed over time.

—Cornell University: “‘Jurassic Worlds’ Might be Easier to Spot than Modern Earth“

Things may not have ended well for dinosaurs on Earth, but Cornell University astronomers say the “light fingerprint” of the conditions that enabled them to emerge here provide a crucial missing piece in our search for signs of life on planets orbiting alien stars. Their analysis of the most recent 540 million years of Earth’s evolution, known as the Phanerozoic Eon, finds that telescopes could better detect potential chemical signatures of life in the atmosphere of an Earth-like exoplanet more closely resembling the age the dinosaurs inhabited than the one we know today.

—UC Riverside: “Giant Planets Cast a Deadly Pall“

Jupiter, by far the biggest planet in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping create a stable environment for life. However, giant planets elsewhere in the universe do not necessarily protect life on their smaller, rocky planet neighbors. A new Astronomical Journal paper details how the pull of massive planets in a nearby star system are likely to toss their Earth-like neighbors out of the “habitable zone.” This zone is defined as the range of distances from a star that are warm enough for liquid water to exist on a planet’s surface, making life possible.

India Has Even Greater Space Ambitions

After recently sending a rover to the Moon and a spaceship to the Sun, India announced plans to build its own space station by 2035 and also send its own astronaut to the Moon by 2040. It also wants to start work on missions to Venus and Mars. How is that for ambitious?

In a press release this week, India’s Prime Minister Shri Narendra Modi stated the following:

Building on the success of the Indian space initiatives, including the recent Chandrayan-3  and Aditya L1 Missions, Prime Minister directed that India should now aim for new and ambitious goals, including setting up ‘Bharatiya Antariksha Station’ (Indian Space Station) by 2035 and sending first Indian to the Moon by 2040.

To realize this Vision, the Department of Space will develop a roadmap for Moon exploration. This will encompass a series of Chandrayaan missions, the development of a Next Generation Launch Vehicle (NGLV), construction of a new launch pad, setting up human-centric Laboratories and associated technologies.

Prime Minister also called upon Indian scientists to work towards interplanetary missions that would include a Venus Orbiter Mission and a Mars Lander.

The space race continues with India showing itself as a strong player in space, potentially replacing Russia as one of the key space-faring nations. It benefits everyone to have more nations studying our solar system. It is unfortunate that Russia has concerned itself with less dignified matters back here on Earth. Maybe it will look to the stars again one day soon.

Space Stories: Roving Students, Preparing for Roman Times, and a New Space Center

Here are some recent stories of interest.

—NASA: “Dozens of Student Teams Worldwide to Compete in NASA Rover Challenge“

NASA has selected 72 student teams to begin an engineering design challenge to build human-powered rovers that will compete next April at the U.S. Space & Rocket Center in Huntsville, Alabama, near the agency’s Marshall Space Flight Center. Celebrating its 30th anniversary in 2024, the Human Exploration Rover Challenge tasks high school, college, and university students to design, build, and test lightweight, human-powered rovers on an obstacle course simulating lunar and Martian terrain, all while completing mission-focused science tasks.

—Space.com: “NASA’s Roman Space Telescope will Launch in 2027. Here’s How Scientists are Getting Ready“

NASA is mobilizing the scientific community to ensure the agency’s next big space telescope will be ready to deliver a “big picture” view of the universe almost immediately after launching. The Nancy Grace Roman Telescope — also known as the Roman Space Telescope, or just Roman — is set to launch in 2027 and will view the cosmos with a staggeringly wide field of view. Its big-picture observations of distant and early galaxies could help scientists solve the mysteries of dark matter and dark energy. Collectively, this so-called dark universe accounts for 95% of the energy and matter in the cosmos, yet the true nature of dark matter and dark energy eludes scientists.

—SF YIMBY: “UC Berkeley Announces $2 Billion Space Center At NASA Ames Research Center“

New plans have been revealed for a $2 billion research center run by UC Berkeley at the NASA Ames Center in Mountain View, Santa Clara County. The Berkeley Space Center, as it will be called, will reshape 36 acres on the sprawling Ames Research Center, providing a hub for future companies to collaborate with the school and NASA scientists & engineers to improve technology for aviation, space exploration, and how people live and work in space.

Audit Results: More Concern About NASA’s Space Launch System

Posted on by onespaceman2000

First, the US Government Accountability Office reported that NASA’s Space Launch System (SLS) is unaffordable, and now NASA’s Office of Inspector General (OIG) doubles down on that earlier finding, reporting that the SLS, a key component of the Artemis program, has costs that are spinning out of control.

In its report, NASA’s Transition of the Space Launch System to a Commercial Services Contract, NASA OIG concludes:

Our analysis shows a single SLS Block 1B will cost at least $2.5 billion to produce—not including Systems Engineering and Integration costs—and NASA’s aspirational goal to achieve a cost savings of 50 percent is highly unrealistic. Specifically, our review determined that cost saving initiatives in several SLS production contracts such as reducing workforce within Boeing’s Stages contract and gaining manufacturing efficiencies with Aerojet Rocketdyne’s RS-25 Restart and Production Contract were not significant and, as a result, a single SLS will cost more than $2 billion through the first 10 SLS rockets produced under [the Exploration Production and Operations Contract].

NASA OIG concludes that maybe other contractors needs to be considered, stating:

Although Congress directed NASA in 2010 to build a heavy-lift rocket and crew capsule using existing contracts from the canceled Constellation effort to meet its space exploration goals, the Agency may soon have more affordable commercial options to carry humans to the Moon and beyond. In our judgment, the Agency should continue to monitor the commercial development of heavy-lift space flight systems and begin discussions of whether it makes financial and strategic sense to consider these options as part of the Agency’s longer-term plans to support its ambitious space exploration goals.

Where are these “more affordable commercial options”? Could it be SpaceX? Blue Origin? If so, let’s start the transition ASAP so that the Moon and Mars remain a realistic goal in the near future. We have plenty of talent in this country and a race to the top is what we need, not a space agency stuck with an Edsel rocket system.

Annual International Mars Society Convention

Posted on by onespaceman2000

If you missed the Annual International Mars Society Convention last weekend in Arizona, you will soon be able to catch up on all of the presentations.

First, you can find abstracts on all of the convention presentations here, which includes many topics, such as:

  • Investigating the Effects of Time-Delayed Communications on the Crew Mission Support;
  • Terraform Earth, then Mars;
  • Methods for Choosing Government Officials in the Mars Context;
  • Space and Ocean exploration as the Alternative to World War III;
  • Agriculture on Mars; and
  • Advancements in Sustainable Materials for Revolutionizing Mars Exploration.

Next, you can find the recordings of many of the presentations from past conventions on the Society’s YouTube page. I expect you will soon see recordings from the latest convention on this same Youtube page as well.

It’s a great service for interested parties who could not make it to the conventions. I recommend you check it out.
