Here’s Why Webb Doesn’t Have Cameras on Board to Livestream its Deployment

As the James Webb Space Telescope unfolds and makes its way to its final destination in space, NASA and ESA have done a great job of sharing the experience with the public. With webcasts, livestreams and a very active social media presence, the JWST team has allowed people to watch over the shoulders of engineers and scientists, as well as ask questions about the process of commissioning the new telescope.

The most often asked question on social media and at several press conferences seems to be, why weren’t cameras put on JWST to provide actual live footage from the telescope? Wouldn’t seeing it firsthand be better than just receiving telemetry?

Every part of the James Webb Space Telescope’s (JWST’s) deployment is nerve-wracking, but some of the most nail-biting moments will happen on New Year’s Eve and New Year’s Day.

JWST’s Precise Launch and Near-Perfect Course Corrections Mean Fuel Savings. And That Means a Longer Mission

After a detailed analysis of where the James Webb Space Telescope is now (Dec. 29, 2021) and how it got there, NASA determined the observatory should have enough propellant to operate in space for significantly more than 10 years in space.

Webb’s mission lifetime was designed to be at least 5-1/2 years, and mission engineers and scientists were hoping for closer to 10 years.

JWST Is On Its Way!

It’s really happening. After all the years of delays, reschedulings, budget shortfalls, and even more delays, the James Webb Space Telescope (JWST) launched on December 25 and is now successfully on its way to is destination at the second LaGrange point (L2), about 1.5 million km (1 million miles) from Earth.

If you celebrate Christmas and are astronomically inclined, the launch feels like a true Christmas miracle.

The footage of JWST’s separation from the Ariane 5 rocket, as seen from a camera on the rocket’s second stage is just absolutely stunning.

After 10 Days of Dangerous, Careful Work, James Webb has Been Fully Fueled up

On Oct. 12^th, 2021, after years of waiting and cost overruns, the James Webb Space Telescope (JWST) finally arrived safely at Europe’s Spaceport in Kourou, French Guiana. The crews began unboxing the next-generation observatory and getting it ready for integration with the Ariane 5 rocket that will take it to space. Then, an “incident” occurred where a clamp band suddenly released, sending vibrations throughout the facility. Once again, the JWST’s launch date was pushed back while crews investigated the source of the problem.

But lo and behold, the due diligence is now done, and the James Webb is back on track! According to the latest news from the ESA, crews have finished fueling the JWST’s thrusters in preparation for its launch, which is scheduled for Dec. 22^nd. The Webb will use these thrusters to make course corrections after separating from the Ariane 5 rocket in orbit, maintaining its prescribed orbit, and repointing the observatory during operations.

Hubble is Fully Operational Once Again

The Hubble Space Telescope hovers at the boundary of Earth and space in this picture, taken after Hubble's second servicing mission in 1997.

In the history of space exploration, a handful of missions have set new records for ruggedness and longevity. On Mars, the undisputed champion is the Opportunity rover, which was slated to run for 90 days but remained in operation for 15 years instead! In orbit around Mars, that honor goes to the 2001 Mars Odyssey, which is still operational 20 years after it arrived around the Red Planet.

In deep space, the title for the longest-running mission goes to the Voyager 1 probe, which has spent the past 44 years exploring the Solar System and what lies beyond. But in Earth orbit, the longevity prize goes to the Hubble Space Telescope (HST), which is once again fully operational after experiencing technical issues. With this latest restoration of operations, Hubble is well on its way to completing 32 years of service.

“Incident” that Occurred During Loading Pushes the Webb Launch Date to Dec. 22nd

At Europe’s Spaceport near Kourou in French Guiana, technicians are busy getting the James Webb Space Telescope (JWST) ready for launch. The observatory arrived at the facility on Oct. 12^th and was placed inside the upper stage of the Ariane 5 rocket that will carry it to space on Nov. 11^th. The upper stage was then hoisted high above the core stage and boosters so that a team of engineers could integrate them.

Unfortunately, an “incident” occurred shortly after when the engineers attempted to attach the upper stage to the launch vehicle adapter (LVA) to the launch vehicle. According to a NASA Blogs post, the incident involved the sudden release of a clamp band (which secures the JWST to the LVA), which sent vibrations throughout the observatory. According to NASA, this incident could push the JWST’s launch date (slated for Dec. 18th) to Dec. 22nd.

Finally! Here’s the Video of Webb’s Unboxing

It’s been a long time coming. Finally, after years of delays and billions of dollars in budget overruns, the James Webb Space Telescope (JWST) is ready to fly. To celebrate the occasion, ESA released a video showing the “unboxing” of one of the most highly advanced technical achievements in human history. It is truly as impressive as it sounds.

Webb has Arrived Safely at the Launch Site

Whew! A major milestone was achieved today in the James Webb Space Telescope’s journey towards launch. After the telescope successfully arrived in French Guiana yesterday following a secretive 16-day ocean journey (with apparently no pirates in sight), today the telescope took a short road trip over land to the ESA’s spaceport in Kourou. JWST is now at the payload processing facility, where staff will start the process of getting the telescope into the Ariane 5 rocket fairing.

Launch is currently scheduled for December 18, 2021 … T-66 days and counting!
