Scheduled for launch in 2027, the Nancy Grace Roman Telescope is slowly being readied for operation. This week, NASA announced that they have started to joined the mission\u2019s telescope, instrument carrier and instruments onto the spacecraft. Having completed the construction, they will now move to the testing phase where the instrument will be subjected to more tests. These will include exposure to electromagnetic radiation expected during launch along with vibration and thermal changes too. If it passes these tests, the new space telescope will be on the home straight.\u00a0<\/p>\n
<\/p>\n The Nancy Grace Roman Space Telescope is often referred to as the Roman Space Telescope. It\u2019s been developed by NASA and was named after former chief astronomer Nance Grace Telescope. It has a mirror 2.4m in diameter so is similar in size to the Hubble Space Telescope but has a wider field of view. On board are instruments that enable it to explore exoplanets and the large scale structure of the universe. It will also investigate the nature of dark energy and try to understand more about the accelerated expansion of the universe through the study of gravitational lenses.\u00a0<\/p>\n It\u2019s fitting that the telescope has been named after Roman who was a leading American astronomer and astrophysicist. She was instrumental in the development of the Hubble Space Telescope so has often been called the \u2018Mother of Hubble.\u2019 She was born on 16 May 1925 and became one of the first female executives of NASA, including a role as Chief of Astronomy.\u00a0<\/p>\n In a recent press release, NASA confirmed that a team of technicians have successfully integrated the telescope with instrument carrier, known as the Instrument Payload Assembly. Two instruments have been installed, the Coronagraph Instrument which will be used to block starlight to reveal and study exoplanets, the Optical Telescope Assembly\u00a0 and the Wide Field Instrument. The Wide Field Instrument is made up of 18 detectors that will give the telescope images with a field 100 times larger than Hubble\u2019s but with the same resolution. I really can\u2019t wait to see the images it produces. The whole assemble is now safely connected to the spacecraft that will take the observatory into its orbit.\u00a0<\/p>\n Mark Clampin, acting Deputy Associate Administrator for NASA\u2019s Science Mission Directorate said \u201cWith this incredible milestone, Roman remains on track for launch and we\u2019re a big step closer to unveiling the comos as never before.\u201d<\/p>\n Launch is a little way off but before then, the instrumentation will under its next testing phase. There has been a significant amount of testing so far but this next test phase is designed to to ensure the individual components operate when integrated. By subjecting it to simulated launch conditions, the tests will check that the vibrations will not cause problems, that the communications equipment won\u2019t create electromagnetic interference and to check, across a range of conditions, that the optics and instrumentation can cope with the predicted thermal variations.\u00a0<\/p>\n On completion of these tests, which are expected to last a few months, the aperture cover will be added to the outer barrel assembly with the solar panels soon after. Once this has been completed, the structure will be added to the spacecraft during autumn. To date though, all is going well with the testing and all is on track for launch no later than May 2027.<\/p>\n Source : NASA Joins Telescope, Instruments to Roman Spacecraft<\/p>\n
