The Micro Focus Universe 2021. The team plans to accelerate its software development with Micro Focus. AI and machine learning can enhance both team performance and the fan viewing experience. He discussed how: Formula E, and the technical landscape that Jaguar Racing navigates every day, is like playing chess at 200 kph. James Barclay, Jaguar Racing Team Director, was the keynote speaker for Micro Focus Universe 2021.

The NASA Goddard Space Flight Center is managing the development effort, and the Space Telescope Science Institute will operate Webb after launch. The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the Sun–Earth L 2 Lagrange point, and a large sunshield made of silicon- and aluminium-coated Kapton will keep its mirror and instruments below 50 K (−223 ☌ −370 ☏). Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, the JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 28.3 μm), which will allow it to observe high redshift objects that are too old and too distant for Hubble to observe. The JWST, which is scheduled to be launched on December 18, 2021, will provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.The primary mirror of the JWST, the Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 m (21 ft) diameter mirror—considerably larger than Hubble's 2.4 m (7 ft 10 in) mirror. It is planned to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission.

Development began in 1996 for a launch that was initially planned for 2007 and a $500 million budget, but the project has had numerous delays and cost overruns, and underwent a major redesign in 2005. In 2021, controversy resulted from NASA's decision to not rename the telescope in response to allegations lacking conclusive evidence that Webb had participated in the purging of LGBTQ individuals from federal jobs. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program.
Problems with the Ariane 5 launch vehicle subsequently pushed the launch date to 18 December 2021. Following work resumption, NASA announced that the launch date had been delayed to 31 October 2021. Work on integration and testing of the telescope was suspended in March 2020 due to the COVID-19 pandemic, adding further delays. Launch was delayed again in June 2018 following recommendations from an independent review board. In March 2018, NASA further delayed the launch after the telescope's sunshield ripped during a practice deployment.
Even where the atmosphere is transparent, many of the target chemical compounds, such as water, carbon dioxide, and methane, also exist in the Earth's atmosphere, vastly complicating analysis. this band is difficult to study from the ground or by existing space telescopes such as HubbleGround-based telescopes must look through Earth's atmosphere, which is opaque in many infrared bands (see figure of atmospheric absorption). cold objects such as debris disks and planets emit most strongly in the infrared high- redshift objects have their visible emissions shifted into the infrared The design emphasizes the near to mid-infrared for three main reasons: The JWST is oriented toward near-infrared astronomy, but can also see orange and red visible light, as well as the mid-infrared region, depending on the instrument.
This arrangement will keep the temperature of the spacecraft below 50 K (−223 ☌ −370 ☏), necessary for infrared observations. Objects near this Lagrange point can orbit the Sun in synchrony with the Earth, allowing the telescope to remain at a roughly constant distance and use a single sunshield to block heat and light from the Sun and Earth. This distance made post-launch repair or upgrade of the JWST hardware virtually impossible with the spaceships available during the telescope design and fabrication stage. By way of comparison, Hubble orbits 550 km (340 mi) above Earth's surface, and the Moon is roughly 400,000 km (250,000 mi) from Earth. The JWST will operate near the Earth–Sun L2 (Lagrange point), approximately 1,500,000 km (930,000 mi) beyond Earth's orbit.
The sunshield is designed to be folded twelve times so that it will fit within the Ariane 5 rocket's payload fairing, which is 4.57 m (15.0 ft) in diameter, and 16.19 m (53.1 ft) long. Accidental tears of the delicate film structure during testing in 2018 were among the factors delaying the project. The five-layer sunshield, each layer as thin as a human hair, is constructed from Kapton E, a commercially available polyimide film from DuPont, with membranes specially coated with aluminum on both sides and doped silicon on the Sun-facing side of the two hottest layers to reflect the Sun's heat back into space. The shielding maintains a stable temperature for the structures on the dark side, which is critical to maintaining precise alignment of the primary mirror segments. Its halo orbit around the L2 point avoids the shadow of the Earth and Moon, maintaining a constant environment for the sunshield and solar arrays. It therefore uses a large sunshield to block light and heat from the Sun, Earth, and Moon, and its position near the Earth–Sun L2 point keeps all three bodies on the same side of the spacecraft at all times.
In addition, there is a fast steering mirror which can adjust its position many times per second to provide image stabilization.Ball Aerospace & Technologies is the principal optical subcontractor for the JWST project, led by prime contractor Northrop Grumman Aerospace Systems, under a contract from the NASA Goddard Space Flight Center, in Greenbelt, Maryland. JWST's optical design is a three-mirror anastigmat, which makes use of curved secondary and tertiary mirrors to deliver images that are free of optical aberrations over a wide field. The Webb telescope will use 126 small motors to occasionally adjust the optics as there is a lack of environmental disturbances of a telescope in space. This is unlike terrestrial telescopes, for example the Keck telescopes, which continually adjust their mirror segments using active optics to overcome the effects of gravitational and wind loading.
It is made with bonded graphite-epoxy composite attached to the underside of Webb's telescope structure. Scientific instruments The Integrated Science Instrument Module (ISIM) is a framework that provides electrical power, computing resources, cooling capability as well as structural stability to the Webb telescope. The final segment of the primary mirror was installed on 3 February 2016, and the secondary mirror was installed on 3 March 2016.
