Hera team congratulates NASA asteroid impactors

ESA’s Hera mission team congratulates their counterparts in NASA’s DART mission team for their historic impact with the Dimorphos asteroid. Moving at 6.1 km per second, the vending-machine-sized Double Asteroid Redirect Test spacecraft struck the 160-m diameter asteroid at 01:15 CEST (00:15 BST) in the early hours of Tuesday morning, in humankind’s first test of the ‘kinetic impactor’ method of planetary defence.

Hurricane Ian prompts NASA to move Artemis moon rocket back to its hangar

Faced with threatening weather from Hurricane Ian, NASA managers decided Monday to haul the $4.1 billion Artemis 1 rocket off its launch pad and back to the protection of the agency’s Vehicle Assembly Building, likely ending any chance of launching the unpiloted moonshot before November.

NASA said in a blog post the decision was made “after additional data gathered overnight did not show improving expected conditions for the Kennedy Space Center area. The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system.”

After two launch scrubs August 29 and September 3 due to hydrogen leaks and other issues, NASA carried out on-pad repairs and targeted a third attempt for Tuesday. But then-Tropical Storm Ian forced NASA to pass that up in favor of a backup opportunity October 2.

Over the weekend, NASA managers monitored the strengthening storm while engineers began rollback preparations, but a final decision was put off until Monday in hopes the forecast would improve enough to preserve the backup launch opportunity. Early Monday, those hopes were dashed, with forecasters predicting torrential rain, lightning and high winds in Brevard County later this week.

The decision was the latest in a series of setbacks for the 330-foot-tall rocket, the most powerful ever built for NASA and the linchpin in the agency’s Artemis moon program.

Jupiter at Opposition 2022, Closest in 59 Years

Be sure to observe Jupiter this week, during its finest apparition of a lifetime.

You’ve never seen Jove like this. Jupiter opposition season for 2022 is upon us tonight, as the King of the Planet shines rising in the east opposite to the setting Sun in the west. This is the very best time to catch Jupiter and its retinue of moons, as they dominate the sky throughout the night. And although Jupiter reaches opposition as seen from the Earth nearly every year, this one is special as it’s the closest to the Earth in our lifetimes, and the nearest for the 21st century.

In fact, at 591 million kilometers (367 million miles) this is the closest approach of Jupiter to the Earth in 59 years, just shy of the average ~600 million kilometers usually quoted for opposition. You have to go alllll the way back to October 8, 1963 to find one closer. In fact, tonight’s opposition won’t be topped until (mark your calendars) next century, on October 7th, 2129. Tonight and for the remainder of the 2022 opposition season, Jove shines at a bright magnitude -2.9 and presents a disk 49.9” across.

Jupiter currently sits in the constellation of Pisces the Fishes, next the northward equinoctial point. Jove also crosses the celestial equator northward today, just nine hours prior to opposition. This means that future oppositions will now begin to favor the northern hemisphere until late 2028.

The orbit of Jupiter versus Earth in 2022 both conspire to make this opposition a close one. We just passed aphelion for Earth in July, and Jupiter passes opposition today on September 26th, 2022 at ~19:00 UT/3:00 PM EDT… just four months prior to perihelion.
