Seeing the universe in the Mid-Infrared with James Webb’s MIRI instrument
The James Webb Space Telescope (JWST), presently tracking toward a launch no earlier than December 22 on an Ariane 5 rocket from the Guiana Space Centre in South America, will revolutionize in-space astronomy, particularly with its Mid-InfraRed Instrument, or MIRI. The instrument itself requires special cooling to drop its temperature to just 6 Kelvin —…

Unfolding the universe: the commissioning process of the James Webb Space Telescope
This December, an Ariane 5 rocket will launch from Kourou, French Guiana carrying the most complicated telescope ever developed — the joint NASA/ESA/CSA James Webb Space Telescope. However, when the telescope launches, it will not immediately be ready for scientific observations. In fact, the telescope won’t perform any observations until about six months after launch.…

Teams evaluate Hubble safe mode event, history of telescope leads to JWST
Thirty-one years after its launch, and 12 years after its most-recent servicing mission, the NASA/ European Space Agency (ESA) Hubble Space Telescope remains in safe mode on orbit as operators work to determine why the iconic observatory ceased science operations at 02:38 EDT on October 25. The latest safe mode event continues to publicly show…

Ariane 5 lofts two satellites in important lead-up to James Webb launch
Close to one year after its last flight, the Ariane 5 ECA has returned to service with its first launch of 2021, lifting off at 21:00 UTC on Friday, July 30. The sixth overall mission for Arianespace this year follows a rework of the payload fairing due to vibration issues that could have endangered payloads.…

James Webb passes critical mission review for 2021 launch, final testing nearing completion
The joint NASA/ESA/CSA James Webb Space Telescope (JWST) has passed its critical final mission analysis review — clearing the way for a late 2021 launch from the Guiana Space Centre in Kourou, French Guiana on an Arianespace Ariane 5 rocket. With this review completed, Arianespace and JWST teams can now begin final launch preparations. With…
