Here are some recent stories of interest.

—NASA/JPL: “NASA to Provide Coverage for Launch of ESA ‘Dark Universe’ Mission“

The ESA (European Space Agency) and SpaceX are targeting no earlier than 11:11 a.m. EDT (8:11 a.m. PDT) Saturday, July 1, to launch the Euclid spacecraft. Euclid is an ESA mission with contributions from NASA that will shed light on the nature of dark matter and dark energy, two of the biggest modern mysteries about the universe.

—Sky&Telescope: “BepiColombo Mission Makes Third Mercury Flyby“

An intrepid space mission had another brief glimpse of its final destination this week, as the European Space Agency’s BepiColombo flew past Mercury for a third time. The team confirms that the spacecraft is in good health post flyby, and that all instruments performed as planned. “Everything went very smoothly with the flyby and the images from the monitoring cameras taken during the close-approach phase of the flyby have been transmitted to the ground,” said Ignacio Clerigo (ESA) in a recent press release. “While the next Mercury flyby isn’t until September 2024, there are still challenges to tackle in the intervening time.”

—Phys.org: “Discovery of a Brown Dwarf Hotter than the Sun“

An international team of astronomers has discovered a planet-like object that is hotter than the sun. Their report has been accepted for publication in the journal Nature Astronomy and is currently available on the arXiv pre-print server. Brown dwarfs are sometimes called failed stars and do not qualify for the category of either a planet or a star. In this new effort, the researchers have identified one that orbits a star so closely that its temperature is hotter than our sun.

Remember International Asteroid Day

Posted on June 26, 2023June 27, 2023 by onespaceman2000

This Friday, June 30th, is International Asteroid Day as adopted by the United Nations to “…observe each year at the international level the anniversary of the Tunguska impact over Siberia, Russian Federation, on 30 June 1908, and to raise public awareness about the asteroid impact hazard.”

NASA has set up page to celebrate the day, as has the European Space Agency. And the Asteroid Foundation is sponsoring a few days of activities leading up to the July 1 Asteroid Day Festival in Luxembourg.

Or you can simply watch your favorite asteroid disaster film on Friday evening.

However you mark the day, enjoy yourself, and look up!

$10 Billion for Some Martian Rocks?

A recent ARS Technica article, “NASA’s Mars Sample Return Has a New Price Tag—and it’s Colossal,” discusses the potential plans to retrieve rocks from the Martian surface at a total cost of $10 billion. This has the potential to crowd out other important NASA projects and may need to be reconsidered at a time of budget constraints.

NASA has been seeking innovative solutions from the private sector to lower the retrieval costs, but the mission may be on hold for some time. Getting rocks from the Moon and even an asteroid seems easy by comparison.

Maybe NASA needs to seen another private sector solution – a study of Martian rocks on the surface of Mars. It may be easier to land a laboratory and conduct long-term experiments in situ rather than attempting a journey back to Earth. It is something to consider for now and may give us quicker access to the rocks.

Of course, we can always wait until Elon Musk lands on the Red Planet and retrieves them.

Space Quote: NASA and Another Type of Tourism

“OceanGate is doing for deep sea exploration, discovery, and research what companies like SpaceX, Blue Origin, World View, and Virgin Galactic are doing for space exploration and discovery…I look forward to supporting OceanGate’s effort to document the Titanic and its role as a deep ocean artificial reef when I join the expedition as a crewmember this summer.“

-Statement by NASA planetary scientist Alan Stern in an OceanGate press release from March 2022. Dr. Stern is best known for his role as the principal investigator of the New Horizons mission to explore Pluto and the Kuiper Belt. The press release also discusses NASA’s assistance to OceanGate in the development of the Titan submersible that is still lost in the Atlantic after a mission to take tourists to see the late Titanic. While Dr. Stern mentions exploration and discovery, this was simply tourism gone wrong. Tourism is a lucrative aspect of the four space companies listed above, but it is not without its risks. Fortunately, Dr. Stern had a good trip last summer, and we can only hope the five individuals on the Titan will also return safely to the surface.

A Day in Astronomy: Sally Ride and Valentina Tereshkova

Posted on June 19, 2023 by onespaceman2000

On this day in 1983, astronaut Sally Ride became the first American woman in space, traveling aboard the shuttle Challenger. And 20 years earlier on the same date, Russian cosmonaut Valentina Tereshkova, the first Russian female in space, returned to Earth aboard Vostok 6, after orbiting the planet 48 times. She still remains the only woman to travel into space on a solo mission.
