Another Delay for Webb, But This Time it’s Because of the Rocket, Not the Telescope

Officials from NASA and ESA this acknowledged the launch of the James Webb Space Telescope will very likely be delayed from the end of October to at least mid-November, 2021. As we reported last month, the usually reliable Ariane 5 has experienced problems on two previous launches where unexpected vehicle accelerations occurred when the fairing separated from the rocket. The fairing is the nose cone used to protect a spacecraft payload during launch and acceleration through Earth’s atmosphere.

“Indeed, there was an anomaly which has been mentioned recently in the media,” said Daniel de Chambure, acting head of Ariane 5 adaptations, during a media briefing on JWST. “The origin of the problem has been found; corrective actions have been taken.”

Nooo! Canadarm2 Hit by a Piece of Space Debris

The International Space Station’s robotic arm, Canadarm2, was struck by a piece of space debris. But luckily, it appears to be only a flesh wound, and the arm has been cleared for nominal operations while analysis on the strike continues.

This is Currently the World’s Largest Iceberg

A gigantic chunk of ice recently broke off from an ice shelf in Antarctica, and is currently the world’s largest iceberg. The iceberg, dubbed A-76, measures around 4,320 square km (1,670 square miles) in size. At 170 km (106 miles) in length and 25 km (15 miles) wide, the iceberg is slightly larger than the Spanish island of Majorca, and bigger than the state of Rhode Island in the US.

A-76 was captured in the above image by ESA’s Copernicus Sentinel-1 satellite. Below is an animation of the iceberg calving off the Ronne Ice Shelf.

Concerns About James Webb’s Ariane 5 Rocket Might Push the Launch Back

A new report from the US Government Accountability Office (GAO) says that the launch of the long-awaited, highly anticipated James Webb Space Telescope (JWST) will very likely be delayed due to an anomaly identified in the Ariane 5 launch vehicle. Launch for JWST is currently scheduled for October 31, 2021, but that date could slip by at least a couple of weeks.

Webb Fully Unfurls for the Last Time on Earth. The Next Time Will Be in Space

The primary mirror of the long-awaited James Webb Space Telescope (JWST) was opened for the last time on Earth before the launch of the observatory, currently scheduled for October 31, 2021.

During some of the final checkouts before the telescope heads to space, engineers commanded the 18 hexagonal mirrors to fully expand and lock into place, just like they will do once the Webb telescope reaches its destination in space.

Extrasolar Object Interceptor Would be Able to Chase Down the Next Oumuamua or Borisov and Actually Return a Sample

What if we had the ability to chase down interstellar objects passing through our Solar System, like Oumuamua or Comet Borisov? Such a spacecraft would need to be ready to go at a moment’s notice, with the capacity to increase speed and change direction quickly.

That’s the idea behind a new mission concept called the Extrasolar Object Interceptor and Sample Return spacecraft. It has received exploratory funding from NASA through its Innovative Advanced Concepts (NIAC) program.

“Bringing back samples from these objects could fundamentally change our view of the universe and our place in it,” says Christopher Morrison, an engineer from the Ultra Safe Nuclear Corporation-Tech (USNC-Tech) who submitted the proposal to NIAC.

Stare Straight Down Into a Giant Storm on Jupiter

A new batch of images recently arrived at Earth from JunoCam, the visible light camera on board the Juno spacecraft at Jupiter. The camera has provided stunning views of the gas giant world since the spacecraft’s arrival in 2016. Citizen scientists and imaging enthusiasts act as the camera’s virtual imaging team, participating in key steps of the process by making suggestions of areas on Jupiter to take pictures and doing the image editing work.

This lead image, edited by Kevin Gill, is another stunner: a look straight down into a giant storm.

And we like Kevin’s attitude about this whole process:

“Put LUCKY on My Tombstone.” Apollo 11 Astronaut Michael Collins Dies at 90

We bid a reluctant but truly fond farewell today to Michael Collins. The NASA astronaut passed away at the age of 90 on April 28, 2021. Collins flew on the historic Apollo 11 mission in 1969, and also on Gemini 10 in 1966.

As Command Module Pilot, Collins was the lone member of the Apollo 11 crew who remained in orbit while his fellow astronauts became the first to land and walk on the Moon. But his endearing nature means he will be most remembered for his wit and humor, his passion and humbleness, his unflappable demeanor, his thoughtful contemplations, and the inspiring words he left behind as a writer of several books.

New Horizons is Now 50 Astronomical Units Away From the Sun

As the New Horizons spacecraft hurtles out towards interstellar space, it has now reached an historical milestone. On April 17, 2021, New Horizons passed 50 astronomical units, or 50 times Earth’s distance from the Sun. It is just the 5^th spacecraft to reach that distance, joining the Voyagers 1 and 2 and the Pioneers 10 and 11.

“You Wouldn’t Believe What I Just Saw:” Ingenuity Helicopter Flies Successfully on Mars

NASA pulled off a Wright Brothers moment on Mars early today by successfully flying the tiny Ingenuity helicopter for approximately 40 seconds.

“We can now say that human beings have flown a rotorcraft on another planet,” said MiMi Aung, Ingenuity’s lead engineer, speaking to her colleagues gathered at the Jet Propulsion Laboratory (JPL) in California to execute and monitor the flight.
